1 Internet of Things, Cryptography, Blockchain and Data security: New Trends and Challenges , Muzafer Saracevic
Security is a very important aspect of a smart system as one of the core smart city components. That is why the concept of smart cities must pay special attention to the security of the individual Internet of Things (IoT) components that make up smart cities. For an IoT system to operate smoothly, all participants in the communication must permit the system to collect information about them - e.g., on the street by various sensors, at home by various devices, such as mobile devices, etc. Such a large set of data collected about the citizens in a smart city is a major security issue [1].
2 Acceleration Analysis of a Rotating Object , Ryspek Usubamatov
Any rotating object with variable velocity about a fixed point generates centrifugal and tangential accelerations that are the components of the inertial forces. The known textbooks of engineering mechanics contain chapters for the acceleration of a ro- tating object that is presented by not accurate mathematical processing. Such a mathematical model for the acceleration of the rotating object yields the incorrect result that leads an unjustified increase in the size of the mechanical component of machines. In engineering, rotating components of machines is a subject of exact computing of inertial forces which non-observance reflects on the reliability of their work. This work considers an analysis of the acceleration of a rotating object at a fixed point and pres- ents the precise mathematical model for its acceleration. Keywords: Radial and Tangential Acceleration; Rotating Object; Fixed Point
3 The Recurrence Inversion of the rotating objects at the Space Stations is the Gyroscopic Effect. , Ryspek Usubamatov, Marek Bergander
The space flights of the astronauts discovered a new physical phenomenon that is recurrence inversions of the rotating objects at the condition of weightlessness. This physical effect is an object of stare studying by scientific researchers of the entire world. They published only a dozen manuscripts with approximated and numerical models and assumptions because of complex prob- lems. The analytical approaches of the new gyroscope theory enabled the description of the physics of the phenomenon of the rotating object in the weightless conditions of space flights. On the rotating object, at the free flight, are acting the inertial forces generated by its circular motions around the earth and its rotating mass. Keywords: Inertial toque; Gyroscope theory; Mathematical model; Inversion

5 DeepGen Network based Voice Conversion , Sheena Christabel Pravin, M Palanivelan, S Saravanan
A DeepGen network is proposed for voice conversion, which is the process of modification of a speech utterance by a source or- ator to that of a target orator, preserving the linguistic contents. Automatic dubbing is an application of speech processing which facilitates the modelling of the large variability of pitch. The proposed DeepGen network automizes voice conversion by taking blocks of consecutive frame-wise linguistic and fundamental frequency features. This block-wise approach models temporal dependencies within the features of the input block. Voice conversion, which is also called as voice cloning has always required significant amount of recorded speech but the proposed DeepGen network intends to convert one voice to another using a rela- tively smaller set of speech samples by bootstrapping samples from a larger speech dataset. The proposed generative model is a variant of the convolutional generative model with encoder and decoder blocks that bring into line the hidden structures of the feature spaces from the source and target voices on a two-stage training process. An attractive and efficient voice conversion is thus obtained in the real-world scenario using the proposed DeepGen network. The novelty of the work lies in the induction of a deep learning generative network for cloning voice in Tamil language. Keywords: DeepGen network; Voice Conversion; Generative Network; Convolutional generative model; Feature spaces

9 Influence of Blasting Activities on Slope Stability: A Case Study , Mohamed Fredj, Riadh Boukarm and Abderrazak Saadoun
In the phosphate mine, the Kef-Essnoun deposit extended to (N75° E), soft and brittle tectonics resulted in an abrupt change in the dip of the phosphate layer flush or the dip angle is subvertical or steeply inclined towards the Southeast and sometimes the Northwest. The overall edge angle of the pit evaluated at 55° for a depth of 75 m. Several incidents of slope failure occurred in the mine, and a considerable disruption to production and monetary losses occurred. It is expected that slope failures may be triggered due to blasting in a steeply sloped laminate. In order to study the causes of slope failures, on the one hand, a back analysis was applied in order to assess the most probable physical and mechanical characteristics of the layer generating the movement, and on the other hand, the slope was analyzed by the limit equilibrium methods (LEM). The calculation of the safety factor (SF) value was carried out under static loads and dynamic loads were taken into account, which led to the conclusion that the dynamic load affects the safety factor. Keywords: Slope stability; Blasting; Safety factor; LEM; Open-pit Mine
10 New Image Encryption Scheme Based on Dynamic Substitution and Hill Cipher , Younes Qobbi, Abdeltif Jarjar, Mohammed Essaid and Abdelhamid Benazzi
In this work, we propose a new color image encryption technique. After transiting of the original image into a vector and de- composing it into blocks of three pixels, along with modifying of a seed block by an initialization vector computed from the plain image, a preliminary confusion will be handled by a substitution matrix developed under the control of the two chaotic maps used in the system. The achieved block will be injected in affine transformation provided by an invertible matrix accompanied by a dynamic translation vector to surmount the problem of null or uniform blocks. The encrypted block will be linked to the original block to setup diffusion and avalanche effect to protect the system from differential attacks. Simulations ap-plied to on a large number of color images prove the robustness of the pro-posed approach against known attacks. Keywords: Chaotic maps; Affine transformation; Substitution
11 Internet of Everything (IoE): Intelligence, Cognition, Catenate , Ganesh Khekare
Internet of Things (IoT) focuses on physical entities whereas Internet of Everything (IoE) focuses on everything viz., People, Pro- cess, Things, Data. IoE intelligently tries to collect and process the data not only from IoT but also from various technologies and even treat people as a node. The IoE is transpiring technology. In the last decade demand for IoE has been increased due to various things like the use of smart devices; increased demand for voice-based services; the concept of smart cities has been evolved; more requirements of processed data in fields of artificial intelligence and machine learning; fog computing, edge computing, deep learn- ing, data analytics, etc. IoE is expected to reach the milestone of 30 billion IoE units at the end of the year 2022. IoE has emerged as a key technology that enables everything to be connected through the internet. As technology is advancing day by day, automa- tion is playing an important role. In every field, IoE is generating a vast amount of data like health systems, traffic systems, smart city monitoring systems, education systems, social networking sites, government organizations, etc. To handle a huge amount of data, a system is required through which it becomes easier to track, analyse, handle, and apply that data in a better way [1].
12 Security of Internet of Things , Smita Sanjay Ambarkar
Internet of Things (IoT) escalates the technology to new heights thereby tremendously increasing the ranges of the connected appli- cations [1]. The applications of IoT mainly include healthcare, agriculture, smart homes, vehicles, mart cities, smart grids etc. The IoT creates revolution in all the applications using the interconnection of embedded devices like sensors, actuators, gateways. The services provided by these IoT based applications are resultantly excellent. However this ubiquitous computing generates the huge data and therefore the protection i.e. providing privacy and security to this data is a prime concern. If the security and privacy of this data is not taken care of then it highly impedes the future development. Many IoT devices uses the open source software which further enhances the insecurity in these devices [2]

15 Material Selection for Manufacturing Disc Brake Rotor for a Racing Go Kart Having Single Hydraulic Disc Brake System , Aman Dharmendra Chheda and Ravikant Hattale
In a racing go kart with single hydraulic disk brake system, disc or rotor is a device for slowing or stopping the motion of a wheel while it runs at a certain speed which converts kinetic energy into heat energy. The widely used brake rotor material is Grey Cast Iron (CGI) which consumes much fuel due to its high specific gravity. Also, it is heavy due to high density which in return affects the performance of the race go kart. The aim of this paper is to develop the material selection method and select the optimum material for the application of brake disc system emphasizing on the substitution of this cast iron by any other lightweight material. Material performance requirements were analysed and alternative solutions were evaluated among cast iron, aluminium 7075 T6, titanium grade 5 alloy, and stainless steel 420. Mechanical properties, thermal properties, FEA (finite element analysis), were used as the key parameters in the material selection stages. The analysis led to Titanium Grade 5 mate- rial as the most appropriate material for brake disc system for a 150-cc racing go kart having single hydraulic disc brake system with the top speed of 110 Kmph. Keywords: Racing Go-Kart; Disc brake rotor; Grey cast iron; Aluminium; Titanium; Stainless steel; Material Selection; Mechan- ical; Thermal; FEA
16 New Heuristic to Optimize the Travelling Salesman Problem , Souhail Dhouib
One of the fundamental combinatorial problems is the Travelling Salesman Problem (TSP) where a salesman is invited to visit all cities with the cheapest cycle. To solve this problem, we designed in [1] a new column row heuristic entitled Dhouib-Matrix-TSP1 (DM- TSP1). DM-TSP1 is characterized by its rapidity to generate an initial basic feasible solution after just n simple iterations where n is the number of cities. Also, DM-TSP1 is branded by its flexibility to use different statistical metrics such as Sum, Min, Range, Standard De- viation, Q1, Q3 etc. Furthermore, inspired from DM-TSP1 we designed in [2, 3] a new stochastic heuristic named Dhouib-Matrix-TSP2, a new iterated metaheuristic in [4] and a new multi-start metaheuristic in [5]

18 Data Science: The Science to understand Oil of 21st Century , Geetika Vashisht and Vishesh Goyal
21st century is all about automation. Human race is obsessed with automation. Taking Amazon’s shopping website as an instance, it uses customers’ shopping data to figure out the shopping patterns and tries to predict your next order and to restock its warehouses nearest to you with what you are most likely to order so they can get products to you as soon as possible. This is called “prime now” under which they deliver 90 percent of things you need within 3 hours. Amazon even has patent called anticipatory shipping under which they will try to deliver things before you even order them based on your data. So, amazon is trying to become a little wishing machine you just open it and you get what you wish for. Also, apps like YouTube and instagram can keep you engaged for hours with- out even needing your input, they have this auto play feature under which you can passively enjoy for hours. So, what is driving all of these advancements? It’s the data -the oil of 21st century and Data science is an ensemble of techniques to extract petrol from this oil which is in a sense useless in its raw form. Now, the question arises that where this data does comes from? It’s from us, everything we do online all of our searches, likes, credit card swipes, Facebook posts everything is being collected into a trillion-dollar data industry. The reason why Facebook, Google, Amazon are the most powerful companies on planet is because last year data surpassed oil in value. These companies have mastered how to use the data they collect efficiently and reap huge number of profits from it. But let’s take a step back and ask ourselves first!
19 Conventional Photogrammetry versus UAV-Photogrammetry , Irineu da Silva
The term photogrammetry has various meanings for different application areas and over time, it has changed its definitions de- pending on the technological stage of its development. Currently, the most adequate definition is to consider it as the methodology for modelling 3D space from 2D images generated by digital sensors. In the beginning, it was just photogrammetry which became Analog Photogrammetry, Analytical Photogrammetry and finally, Digital Photogrammetry, which is being replaced by two competing terms which are conventional photogrammetry and UAV-photogrammetry. The question here is whether they are sufficiently different to deserve two distinct denominations

21 Contribution of Creative Mathematicians in the Development of Machine Learning , Muzafer Saracevic and Dzenis Pepic
Machine Learning and Deep Learning are two areas in Computer Science that are expanding and are increasingly finding applica- tions in solving the real problems of the industry. They are related to developing the ability to “learn” computers without prior explicit programming, but rather a conceptually inverse process is already taking place, in which the machine uses a huge amount of data and recognizes laws due to which certain processes occur. Machine learning relies on so-called models, which represent a wide range of mathematical functions that originally belong to different mathematical disciplines, such as algebra, mathematical analysis, probabili- ty, and statistics, or discrete mathematics. And all this is simplified through various computer software and tools.

24 UVC Based Sanitizing Chamber , Dr. Syed Sumera Ali, Suryawanshi Ajit Rohidas, Karpe Dipika Aniruddha and Agrawal Shashank Radheshyam
In this pandemic situation of COVID-19, sanitizing is one of the most important and crucial activity which needs to be done timely. As per the report issued by medical experts COVID-19 can leave on the surfaces that the patient or a person suffering from Covid-19 may touch timely. The molecules of virus can land on surfaces or devices of daily use and thus infecting the it and making it more prone to be infectious. The contagious mode of the virus makes it more deadly and results in extreme precautions to be taken in order to prevent an individual from getting infected by the virus. In order to overcome this problem sanitizing chamber can be used to sterilize the equipment and make them ready to use again for the users. In a country with less developed medical facilities and services sterilization proves to be a useful step. The medical equipment like masks, mobiles, wallet, small clothes, etc. can also cause viruses. Our project provides support to healthcare organization’s looking for alternative methods to preserve and reuse such equipment. In the context of COVID-19, everyone has to protect themselves and for that, everyone is doing what they need to do to pro- tect themselves, but we are making this project to sanitize the things that can be infected due to certain things. People are using sanitizer to protect themselves from getting infected but if they can’t use sanitizer on some things then they can be bad because there are different types of sanitizers available in the market but they are in liquid form and you can use liquid sanitizer on your mobile, electronics, and money. Can’t use and to avoid the risk that a person can be infected from this thing, we have started this project in which you can sanitize your mobile, electronics, money, etc., and its use will not spoil those things, because it is not in liquid form, but in light form. Destroys germs. Keywords: UVC; COVID-19

27 Engineering and the Environment , Mainak Ghosal
We all know that our environment is a complex of physical, chemical, and biotic factors that act upon all living beings or communi- ties. In Dictionary environment simply means ‘surroundings’ (environ) and it is the aggregate of that which includes social & cultural conditions or influences. The environment provides us food (Roti), clothing (Kapda), shelter (Makan), and fulfills all our desires and needs whether big or small. Moreover, the entire life support or ecological cycles of humans depends wholly on the environment. In ad- dition, it also helps in supporting and maintaining various other thousands of ecological cycles sustaining on earth. The environment we live in is made up of natural or geographical and built or man-made. We Indians have a tradition of worshipping our environment as Vaastu-Shastra breaks down it into five (5) parts namely-fire, air, water, earth & space. Even before India’s independence in 1947, several environmental legislations existed but only after the UN Conference on the Human Environment (Stockholm, 1972)did the National Council for Environmental Policy and Planning within the Department of Science and Technology was setup in 1972. This Council late revolved into a full-fledged Ministry of Environment and Forests (MoEF) in 1985 which today is the apex administrative body in the country for regulating and ensuring environmental protection. India is the 1st country to effect such legislation where con- stitutional sanction was given to environmental concerns through the 42 nd Amendment, which incorporated them into the Directive Principles of State Policy and Fundamental Rights and Duties. Last but not the least, it may not be exaggerated to mention that animals (e.g., Crayfish-quality of freshwater; Corals- seawater rise and sea temperature fluctuation, which in turn are signals of climate change; Peregrine falcons-an indicator of pesticides like DDT; Frogs/toads-pollution, etc.) often act as an indicator which offers key clues to environmental change and pollution and by monitoring changes in the behavior, physiology, or the number of an indicator species, scientists can monitor the health of its whole environment.
28 Physics of Gyroscopic Effects , Ryspek Usubamatov
The history of sciences contains unusual examples of the achievements in physics and mathematics, which methods did not use for problems in applied science during the centuries. One such example is the intricate motions and acting forces of the ordinary revolving disc, which theory was worked out in our time. The top toys were invented in ancient times, which intricate motions aston- ished the people of different civilizations. The unusual motions and acting forces of the top toys today are called gyro effects [1].
29 Vibration Attenuation and Joint Navigation through Robust Control System Hardware for Multi-Degrees-of-Freedom Flexible Robots , Pratik Chothe, Shreyash Gajlekar, Aniket Bhelsaikar, Viinod Atpadkar, Nilesh Uke and Debanik Roy
The inherent vibration occurring due to compliance of Flexible Robotic System (FRS) provides numerous challenges to achieve accuracy at the end-effector of the FRS. This paper focuses on the study of influence of electronic control system hardware over electromechanical output of the FRS. The paper provides an insight to the relationship between drive current and motor torque with vibrations in the system. Design details of the novel indigenously-developed control electronics and, finally the controller of the prototype FRS will be reported in this paper, backed up by the glimpses of mechanical hardware. The performance and robustness of the prototype FRS will be finally discussed based on some representative analysis and results thereof. We will dis- cuss about implementing various trajectory functions in the control program of the prototype FRS. The paper will further lead to modified linear trajectory where parabolic blends are introduced to reduce the infinite acceleration, which would eventually reduce the vibration in the links of the FRS.

30 Ontologies in Various Domains: A New Perspective of Ideas , Tanaya Das
The term ontology came from two Greek words i.e., “Onto” and “logos”. It denotes “study or knowledge about everything that ac- tually exists”. Philosophers defined the word “Ontology” in their own way. It is discipline of philosophy [1] that deals with structures of things, events, processes, and relations in every aspect of reality. In recent years, research in multidisciplinary fields has exploded in various sectors or domain. “Ontology” term from philosophy was adapted and repurposed to fit the needs of sectors or domain. Thecore goal of ontologies is to provide a vision of a domain. Ontologies consist of all relevant domain-specific terminologies and con- nections that help to identify core concepts and accumulate critical information related to the domain. Nowadays, ontology is deployed in various fields to capture the domain knowledge.

A small oil field has been unknown in the past 30 years, why in the last 10 years it created an amazing miracle in China and even in the global oil industry? To answer this question scientifically, you have to have a scientific theory. In terms of depth and breadth of this problem, undoubtedly the most scientific theory is systems engineering theory; and from the perspective of oil- field production growth referred to on this issue, the most appropriate theory is man-machine-environment system engineering (MMESE) theory. Changqing oilfield applied MMESE to develop low-permeability reservoirs with extraordinary results, proving the value of MMESE. Keywords: Application; MMESE; Changqing oilfield
33 Revisiting Global University Rankings , R Natarajan, P N Razdan and Madhu B K
Interest in and popularity of global university rankings have been on the rise worldwide. They have been utilized by the several stakeholders for different types of decision making. There is also general recognition that no ranking system is perfect and there are specific criticisms of each ranking system. One of the most controversial parameters is Perception which THE and QS claim to be the centerpiece of their systems and allot about half of the overall score to it. This aspect is examined here with respect to THE and QS global ranking systems and the national NIRF rankings, by comparing the scores with and without inclusion of the perception scores. It is argued that Perception is entirely subjective and comes in the way of providing a level playing field for all institutions.

35 Circular Economy and Sustainability , Sharad Gupta
Circular economy offers an alternative to linear economy model and can provide up to $4.5 trillion in economic benefits to 2030. It would give these benefits by promoting the removal of waste and the persistent safe use of natural resources. This transition to circular economy would requires unique collaboration considering that only 8.6% of the world is circular today (Gawel, A, 2021) [2]. For this long journey, research must look at sustainability from the perspective of consumers also who consider sustainability in different buying situations (Gupta & Sinha, 2015) [7] more so during this time of COVID19 pandemic (BCG, 2021) [1]. Production and consumption represent two sides of the same coin. Therefore, research must look at both production as well as consumption for increasing circularity in pursuit of sustainability. We now examine circular economy and sustainability from production perspective and then from consumption perspective.

39 Scheduling with Maintenance Technique in Dynamic Job Shop System including Machine Breakdowns, Kaouther Ben Ali, AchrafJabeur Telmodi and Said Gattoufi
Machine scheduling is concerned with the problem of optimally scheduling available machines. However, scheduling literature review has been focused on common assumptions that machines are available at all times. The availability constraint is may not frequency occurred because a machine may become unavailable during a certain periods of time. This paper is addressed to study the problem of job shop in dynamic environment with the risk of random machine breakdown. It is considered a NP Hard optimization problem. Predictive maintenance is an answer to prevent the system from risk of machine breakdown. The objective function is to minimize the completion time of the last job being executed. Hence, we propose a met heuristic approach based on GA approach to solve the issue. Experimentation results assume that the used approach based on maintenance function is required to produce, for each machine, the adequate scheduling plan.

40 Financial Management of Micro, Small and Medium Enterprises during COVID Times–Analytical Review with reference to Indian MSMEs, Abhijit Kelkar
COVID-19 outburst has harmed not only the Indian economy’s economic and social activities, but also the global economy as a whole. Cushioning levels of shocks especially for financial downs remain to be restricted for MSMEs. The main reason is due to limited potential for raising and management of funds. This generates a significant impact on MSMEs. This paper seeks to evalu- ate MSMEs’ contribution towards the Indian economy along with analyzing the barriers and challenges that existed prior to and during the COVID period. Challenges were indeed in presence before COVID 19 also but during and post COVID 19, their intensity, severity and scope have changed a lot. In addition, a few more are also emerged newly. To analyze the overall effect and impact of these challenges, a range of descriptive statistics along with correlation and co-integration is used. Cointegration is used to analyze the relation among variables such the amount of MSMEs, investment amount, employment, etc. output. This pandemic has crashed into MSMEs like a tons of bricks. COVID 19 remains to be a huge uncertainty and with the understood scope of this uncertainty so far, government must establish a continuous monitoring mechanism and announce early corrective actions to restore confidence in the MSMEs sector. MSMEs should be encouraged to connect to the internet market and fiscal incentives for this sector should also be strengthened. The Indian government should take a variety of initiatives to improve SMEs in India and achieve the goal of making India self-sufficient.
41 Vibration Signature Based Monitoring on FSW Process and Verification by FEA, Akshay Todakar, Nakandhrakumar R S, M Ramakrishnan and V Meenakshisundaram
Experimental study conducted during joining butt weld in FSW process on Al 6061 alloy of size 50 mm width X 100 mm length X 8 mm thickness of two plates wherein the effect of the interaction between the plates, tool and the vibration that occurs during the process are investigated, are reported. In this study, joining sides of the workpiece samples are artificially induced with air gaps of drilled holes in 2mm, 3mm, 5 mm diameter holes and 3mm width X 4 mm depth of slots in random distances. The vibra- tion behaviour of the tool and workpiece joining system are characterized by a frequencies arrived in modal analysis using Finite Element Analysis (FEA), each mode corresponds to tool and workpiece system. Variations in the amplitudes of vibration signals in the particular range of frequencies from 6.0 to 7.0 kHz are proportional to workpiece and significant changes in linear pattern indicate the defective and steady joining area of workpiece. So, this method is effective in monitoring of workpiece joining in FSW process. The Fast Fourier Transform (FFT) analysis of vibration signal shows the changes in individual frequencies and is used for identifying the frequency range of monitoring workpiece with gap and without gap conditions. The steady joining portions cause the vibration which corresponds to 4thregion frequencies of workpiece.
42 The Universality, Major Harm and Deep Causes of Irrational Construction Periods, Sun Jiajun
Rome was not built in a day, the Long March was not completed in one step, and the project period has its own objective laws. Respecting the objective law of the project duration, consciously using this law to serve the project, and acknowledging that the project duration is incompressible under the premise of various constraints are the theoretical qualities that every project manager should have. It is an extremely wrong concept to regard the project duration as a “sponge that is still empty at will be squeezed”, and the irrational construction period under the guidance of this concept is a universal problem in project manage- ment.

It’s high time we focus on the value of the following potential opportunities oth- erwise we may again miss the bus.
44 Analysis and Application of Pavement Interlayer Properties, Chaohua Zhao and Kang Su
The load varies with the thickness of the pavement, so there are different layers in pavement structures, between which inter- layer interfaces contacting with each other inevitably in different modes. In this paper, based on investigation and analysis, the interlayer contact modes of pavement structures are classified as “interlayer coupling” and “interlayer connection”, which are defined according to their mechanical properties. Based on the existing ordinary cement concrete pavement, this paper analyzes the formation, development and evolution of interlayer coupling, and finds that the failure of interlayer coupling is the cause of early pavement damage. Cement pavement structure with isolating course is proposed as a method and countermeasure to elim- inate these hazards, the feasibility of which is verified theoretically. Conditions and approaches achieving interlayer connection in pavement structures are proposed as well. Application of interlayer connection is introduced using a novel type of polymer skeleton porous concrete pavement structure as an example.

45 Main Evaluation Factors of Fractured Formation Leakage in Bohai Bay Basin, Jiang Shao-long, Zhang Guo-qiang, MU Gui-peng, Yuan Ren-guo and Xin Zhao-ling
In the central area of the Bohai Oilfield including Bozhong block, the geological structure is complex, faults and fractures are extensively developed and the formation is broken. As consequence, there is leakage to some extent in most exploratory wells in Bozhong Block, significantly affecting the drilling efficiency and increasing drilling risks. The problem of well leakage in this block needs to be addressed urgently. For this purpose, the research group firstly researches into the wellbore leakage mecha- nism, and then establishes a regional leakage pressure prediction model by depiction of the main controlling factors of leakage and preliminarily obtains the following findings: (1) the leakage in Bozhong Block mainly occurs at the depth of 2700-3400m, with Member 2 and Member 3 of Shahejie Formation as the main leakage zones and the fractures and faults as the main leakage passages; (2) the fracture index that can most clearly reflect the well leakage characteristics in Bozhong Block is the fracture evaluation index obtained using the resistivity ratio method, and may be considered as a main controlling factor for evaluation of fractured leakage; (3) according to the statistics on leakage of 22 wells in Bozhong Block, there are nine wells with leakage, totaling 13 leakage points. Based on the statistics and modeling, a leakage pressure prediction model for this block is obtained preliminarily. The research on the leakage mechanism and leakage pressure prediction of fractured formation in Bozhong Block is helpful for reasonable optimization of borehole trajectory, improvement of leakage control of fractured reservoirs, reduction of drilling cost and raising of operation efficiency.

46 Deep Learning based Object Detection Methods: A Review, Divya Mishra
Recently, object detection has become one of the effective and popular trends in computer vision to deal with numerous appli- cations such as in medical image processing of breast cancer, skin cancer, brain injuries, blood cells, and more. Also, it is used in video surveillance stations for real-time monitoring of crowd and anomaly detection. The application is widely used in satellite images and astronomy, fraud detection, and in the field of remote sensing to detect disaster-prone areas from satellite images so that important measures can be taken at the correct time to overcome or reduce the loss of life and property. For example, in medical applications earlier diagnosis procedures usually tend to figure out early diabetes, cancer and a few more diseases. Despite many existing object detection methods in state-of-the-art literature, it is getting harder to identify the best fit model for the specific application or dataset. Therefore, it is highly important and much needed to bring all the existing techniques to a single platform and mention their advantages and limitations. In this paper, a thorough literature review and comparison of vari- ous existing deep learning-based object detection methods are presented using three different parameters named mean average precision, frames per second, and data set used. Such information is useful for researchers and practitioners to identify the better approaches among the others easily according to the dataset in hand.

47 Application of Java Relationship Graphs to Academics for Detection of Plagiarism in Java Projects, Divya Tyagi, Ritu Arora and Yashvardhan Sharma
In today’s online learning environment, plagiarism detection tools are increasingly used by teachers and instructors to restrain students from plagiarism. Moreover, need for plagiarism detection tools to detect plagiarism in programming assignments has also increased manifolds. In this paper, we present the application of Neo4j Graph Databases to detect similarity between Java program submissions by students, in academics. This is done by converting a Java program into a specialized dependency graph and then implementing various comparison techniques on this graph. The two graph comparison techniques proposed and implemented in this paper are based on structural comparison of graphs by node-type count comparison and elemental compar- ison of method nodes in graphs by body-element-count comparison. The results of these two techniques are combined with the call graph-based technique, proposed in an earlier work, to calculate overall similarity index between program codes. This study captures a large category of changes that may be introduced to the code for plagiarism.

48 Namúli Mount, the Identity and the Landscape of Gurué, Rute Sousa Matos
This reflection arises from a look at the African landscape, the mountains and their ecosystems, the agriculture, the heri- tage, communities and identity. This is about the landscape, which integrates man and territory, and its multifunctionality that includes the production system (agriculture), protection (ecosystems, flows and ecological processes) and the cultural system (communities and the way they build space). This set constitutes a complex and relational system resulting in the identity of a region and the communities that inhabit it. The excessive exploitation of natural resources and the tendency towards the growth of an economy based on tourism, causes the transformation of the landscape to occur in the sense of losing its character, its culture and, consequently, its identity. The objective of this work is to identify invariants of this landscape, which can be considered in future proposals for planning and management plans for this area, in order to preserve the Gurué landscape and its identity. Through an analysis of the existing cartography and bibliography, the natural systems, their flows and processes and the cultural and heritage elements of this area were first identified and characterized. Based on this diagnostic phase, invariant el- ements (either natural or cultural) that determine the culture and identity of this landscape and must therefore be safeguarded and maintained, were identified. The guidelines appear later, in this sense - the preservation of fundamental values in the culture and identity of Namúli Mount and the landscape of Gurué, where it is inserted.

49 Natural Farmed Intelligence (NFI): Possibility against Advanced Artificial Intelligence, Md Sadique Shaikh
Today’s near future and far future all technologies centrally based on “ARTIFICIAL INTELLIGENCE” (Man Made) and becoming more and more precise and accurate everyday as compare to human “NATURAL INTELLIGENCE” (God Made) though human invented, engineered and implement A.I as its pioneer. In every field A.I (Man Made) beat to N.I (God Made) as we realized and surrounded with minor to minor and major to major A.I based Computing, Communication, Mobiles, Internet, Internet of Everything with smart A.I Processed and controlled devices having RFIDs in Ubiquitous communication network, space science, medical robotics, industrial robotics, electronic automation, smart appliances and Humanoid robotics. One day might be condition would be A.I programme itself according its need of execution and ruled on N.I that means on Human Civilization also called “Robotics Violence”. More and more min- iaturized A.I chip perform thousand times greater operations/tasks/processes from it’s previous due to the Nanotechnology and ad- vanced Electronics. Hence A.I is good but equally bad for mankind and even till date we are on just trial basis to implement human-like “Robotics Emotions” in A.I, Bionic Brain and Humanoid. Therefore today I am diverting my readers from A.I to towards “Synthetic Biology”, “Human Biology” and “Neuroscience”. We much familiar with Biology and Neuroscience but let me explain in brief about syn- thetic biology or SynBio is “a multidisciplinary domains of research integrated/cascade with atoms/cells manipulation to form/farm/ fabricate new biological devices, systems and parts or to reengineer and make more effective systems, parts those are already available in nature using biotechnology, genetic engineering, molecular biology, system biology, biophysics, membrane science, molecular en- gineering, chemical, biological, mechanical, computer and nanotechnology engineering’s”. Now what is my intention to discuss above here as likewise using material physics and electronics we mimic and engineer A.I from N.I with the help of neuroscience equally true and possible using Biology, Synthetic Biology and Neuroscience we mimic and engineer N.I itself to form External N.I that is similar like our human brain with N.I inside our skull can we able to farm same biological brain outside the human body using “Brain Cells” and the answer is Big “Yes”. Even researchers in “Petri Dish” also known as Petri Plate/Cell-culture Dish widely used in all walks of biological experiments to store, manipulate, engineer and performance check of cells , hence Brain cells manipulated and engineered in Petri Dish to form Human Brain like Natural Intelligence (N.I). This farmed neural schema in Petri Dish is N.I which is the great contribution to mankind and reported this little brain cells in Petri dish programmed and learn to them few games and results astonish its play the game 10 times faster than Artificial Intelligence. Hence today humankind just engineered and stored single “Neural Schema” network of brain cells and learn them to play chess which beat to A.I as one small unit in Petri Dish will be tomorrow hopes to farm complete human brain (N.I) outside using synthetic biology and I named the technology “Natural Farmed Intelligence (NFI)”. The amazing fact about NFI is its exactly same like human brain but several time faster and accurate to it in comparison, because it in unprogram from families, relation, responsibilities, stressors as affect on Human Brain Inside and work ultra high speed. Another good thing since NFI mimic and engineer from Brain and made up of “Brain Cells” as Building Block hence to implement exact same human brain-like emo- tions in it very easily which work in favor of mankind and against of “Robotics or A.I Violence” in future.

Let me first recall you again “Natural Farmed Intelligence (NFI)” than after approach how to Bumanoid possible using NFI. As using material physics and electronics we mimic and engineer A.I from N.I with the help of neuroscience equally true and possible using Biology, Synthetic Biology and Neuroscience we mimic and engineer N.I itself to form External N.I that is similar like our human brain with N.I inside our skull can we able to farm same biological brain outside the human body using “Brain Cells” and the answer is Big “Yes”. Even researchers in “Petri Dish” also known as Petri Plate/Cell-culture Dish widely used in all walks of biological exper- iments to store, manipulate, engineer and performance check of cells, hence Brain cells manipulated and engineered in Petri Dish to form Human Brain like Natural Intelligence (N.I).

55 An overview on 5G mobile network antennas: Trends and Challenges, Moutaouakil Abdelhakim
To deploy the 5G mobile network, operators must install tens of thousands of new antennas. They are one of the major technological developments of 5G. For 5G, as for all other generations of mobile networks, antennas are an essential support. They are the ones that relay and transmit the signal. Without antennas, there are no waves, and therefore no 5G network. In order for the new 5G mobile net- work to work, operators must deploy tens of thousands of new antennas. Indeed, 5G antennas are totally different from 4G antennas. And, they contain some of the major technological innovations of 5G, which give the new mobile network its uniqueness. They are called Massive Mimo, beamforming, Small cells [1].
56 Basic Evaluation for Dynamic Behavior of Waterdrop on Line-patterned Silicone Surface using Equation of Motion, Kenji Yanagisawa and Chinatsu Saito
Inspired by the water-repellent and self-cleaning properties of the lotus leaf in the natural world, artificial superhydrophobic surfaces have generated extensive attention in academia and industry. Hydrophobicity and the sliding behavior of waterdrops is a very important phenomenon in our daily life as well as in many industrial processes. However, the difference between these two phenomena is not well understood. This study was performed to predict movement of waterdrop on surfaces of silicone sheet and was focused on interface resistive forces between waterdrop and surfaces. Various hydrophobic sheets having dif- ferent the waterdrop contact ratio (the ratio of the contact area between the waterdrop and the sheet) were prepared. And the relationships between the sliding angles, the sliding velocities and the surface structure were investigated. Equation of motion is used to calculate the interface resistive forces from the sliding angle and the sliding velocities. As the result of calculation, interface resistive forces between waterdrop and the surfaces are equivalent to force of the gravity. The interface resistive forces decrease with decreasing the waterdrop contact ratio. Sliding velocities seems to affect interface resistive forces. This research clarifies that sliding velocity and interface resistive forces are related to positive correlation by the waterdrop contact ratio. The relationship may help prediction of movement of drops on surfaces.

57 Power Quality Improvement Using Modified ANFIS in Hybrid Miniature Solar Power Generation Units through Reduction of Total Harmonic Distortion, J Samuel Manoharan
Research in solar ponds have been on an increasing trend in recent times as an alternative for fast depleting non-renewable source of energy. Solar ponds are artificial saline water holding structures which are capable of retaining heat in the saline mol- ecules. A suitable thermo electric generator is capable of extracting power from these ponds. A miniature solar pond has been taken up for experimentation and output power quality improvement has been achieved by reducing the total harmonic distor- tion using an adaptive neuro fuzzy inference system. Experimental results justify power quality improvement using the proposed learning based approach.

58 Gamified Interaction’s Impact on Consumers’ Purchasing Decisions: A Health and Fitness apps Perspective, Abhishek Yadav
The ultimate goal of any brand is to get positive responses from customers both emotionally and behaviorally for its market- ing activities. This study examined how gamified interactions on health and fitness applications impacted consumers’ purchase intentions and assessed the role of positive emotions and brand engagement in developing this relationship. Data were collected from users of health and fitness apps through a self-administered questionnaire and analyzed using the partial least square structural equation modelling technique. The findings suggest a strong indirect relationship between gamification and purchase intention. The study also found positive emotions and brand engagement to be significant sequential mediators of the gamifica- tion-purchase intention relationship. Keywords: Health and fitness application; gamification; purchase intention; positive emotion; brand engagement
59 A Complete Assessment of Tribo-corrosive Behaviour of CI Engine Using Emulsified Dual Fuel Bio-Diesel Blend, Sajan Chourasia, NimeshGajjar, Harshal Oza and Nirav Joshi
Biodiesel is relatively higher corrosive compare to Diesel. Biodiesel is self-oxidation in nature. The current investigations are to determine the tribological and corrosive behavior of biodiesel and their dual biodiesel emulsified fuel blend on CI engine vital parts (i.e., Piston, Valves, Cylinder liner, Cylinder head, Fuel pump, Bearings). The emulsified fuel was made from dual biodiesel (i.e., Neem and Palm) with Diesel and water. The tribological and corrosive effects were performed on metal surfaces of Copper, Aluminum, and Iron. These metals were selected based on the base composition of engine vita parts. A static immersion test was conducted for corrosion for 150 days at room temperature and for tribology, a pin-on-disc apparatus test was performed. These test also includes scanning electron microscopic, weight, dimension and physical visualization analysis of corroded and worn- out metal surfaces. To identify the cause of the corrosion, wear on the metal surface, the Gas chromatography-mass spectrometry test has been conducted. This test will also help to determine the chemical composition of the test fuels. It has been observed that biodiesels have good anti-wear properties in comparison to Diesel and emulsified fuel. On the other hand, Diesel and emulsified fuel show good corrosive properties compare to biodiesels.

60 The “Ivermectin” to South Africa’s Educational Landscape, Pariksha Singh, Ciska Snyman and Jayshree Harangee
Globalisation is making the threats we face more intertwined. In addition to the COVID-19 outbreak crossing international borders, South Africa is experiencing devastating floods. Despite its diversity, it has affected everyone, regardless of nationality, education level, income level, and gender. Despite this, the repercussions have disproportionately impacted the most disadvantaged. Education is no different. With the help of parents coupled with the desire to learn, students from wealthy homes may be able to make their way past restricted higher education institutes to other learning prospects. When institutions shifted fully online, those from low-income fam- ilies were disadvantaged. These disasters have brought several shortcomings and inequities in our educational institutions, ranging from a scarcity of access to the internet, connectivity issues, and computers required for online learning to the absence of supportive surroundings needed to engage with learning to a mismatch of resources and necessities.

67 Human Intelligence and Machines, Tilottama Goswami
Current trends in engineering and technology have made a great impact in automation on a day-to-day basis in almost every field. The advantages of automation are manifold -reducing human interventions, increase in productivity, reducing human errors, and to enhance their capability to work; especially in hazardous and danger zone areas. Human labor-intensive tasks/repetitive tasks where human fatigue and error is a usual phenomenon are usually good candidates for automation. Can automation succeed in tasks which need human expertise and intelligence? Its limitations does not allow it to automate every task. Automation is a straightforward algorithm which takes input data and produces output according to the algorithm. When intelligence and cognitive capabilities have to be embedded in a machine to mimic the way human would execute the task, automation becomes conceptually closer to Artificial Intelligence (AI).
68 Predicting Global Average Land Temperatures Using Microsoft Azure Machine Learning Studio, Sagar Tewari, Sarthak Agarwal and Madhulika Bhatia
To accurately calculate the global average temperature has proven to be an arduous task since the 19th century, the major rea- sons are maintaining accurate records of the same locations over a lengthy period which has strained the meteorologists, espe- cially in places located remotely, like mountains or deserts. This is the reason meteorologists use global averages which generally span over 3 decades to give perspective and context to information. We decided to use the Linear Regression Model to achieve this task at hand. Linear regression is an algorithm which is used for determining the relationship between an dependent variable and some independent variables which are also known as sca- lar response explanatory variables respectively. The relationship between dependent and independent variables are calculated using predictor functions which are linear in nature whose parameters which are not known are found out through the means of the data provided. Hence, it is paramount that we give our model a clean and digestible data so that it learns well and predicts accurately. It’s equally important that we maintain the dimensions of the data and be careful that it is not too high or not too low, it should be just right. We also employed the Pearson’s Correlation method for Feature Selection. After which we also tuned the hyperparameters among other things to gain the most suitable parameters for the model. Finally, we compared our results from normal model generation to hyperparameter tuned model. Keywords: AZURE; Machine Learning; Linear Regression; Pearson’s Correlation Coefficient
69 Additive Manufacturing Technologies: A Pathway to Organ Printing, Prajwal Agrawal
With the advent of additive manufacturing, various processes have been developed over the years. A prominent example is bioprint- ing. The technology involves the use of biocompatible materials and living cells to construct functional structures and constructs that mimic the properties of human body tissues [1]. It is estimated that 20 people die every day due to a lack of organ transplantation in the United States alone [2]. With the development of new diseases and an increasing population, this number is expected to increase over time. It is possible for bioprinting to provide a solution for this issue, but it will need many modifications and development to result in a living organ with multiple cell types and materials [3].
70 Experimental Study of the Consolidation Characteristics of Saturated and Unsaturated Municipal Solid Waste (MSW) Using Large Scale Consolidometer, Gajrawala Tirth Nikhilbhai, Dr. M. V. Shah and Prof. Shalini. R. Singh
Municipal Solid Waste is a heterogeneous mixture of various materials such as food, glass, soil, ash, plastic, etc. Since there are no generally accepted sampling and testing procedures for waste materials, principles of soil mechanics. A good understanding of the properties of unsaturated Municipal solid waste is required for the design of the underground pipelines. Settlement pre- diction is an important issue to guarantee any post-closure structures on landfills. The present study is an attempt to determine the consolidation characteristics of saturated and unsaturated MSW from the Pirana landfill site, Ahmedabad (India) using a large size Consolidometer having an aspect ratio of 1:0.635. At present five tests were conducted on saturated municipal solid waste for 100% saturation and five on unsaturated MSW keeping a degree of saturation=50% at different water contents. The tests were carried out at the pressure of 20kpa, 40kpa, 80kpa, 160kpa, and 320kpa respectively. The consolidation settlement resulted in both types of waste being compared. It was concluded that the saturated MSW compacted on the dry side of the opti- mum has less settlement compared to the MSW compacted on the wet side of the optimum while the time taken for the unsatu- rated MSW was slightly higher as compared to that of the saturated MSW.

71 Evaluation of Green Total Factor Productivity in the Yellow River Basin of China, Jingcheng Li, Guangwei Rui and Xinyi Mei
The Yellow River Basin is an important energy production base, heavy industry base, and grain production area in China. Meanwhile, the ecological environment in this area is also very fragile. The success of carbon emission control in this region is re- lated to whether China can complete its vision of carbon peak and carbon neutralization on time. Taking carbon emissions as the non-ideal output of the economy into the nonparametric DEA Malmquist index model, this paper measures the green Malmquist index of 9 provinces in the Yellow River Basin from 2014 to 2020 and analyzes the impact of the green Malmquist index, green technology efficiency and green technology progress rate on the regional economic growth gap and its time evolution trend. The results show that the green total factor productivity of the region shows a fluctuating upward trend from 2014 to 2020, but the direction of efficiency progress is negative. Therefore, the Yellow River Basin needs to reform the management system of high energy-consuming industries and strengthen environmental supervision in the future. In addition, the changes in green total factor productivity in various provinces show high heterogeneity, which poses new challenges to the formulation of emission reduction policies.

73 Social Issues/Challenges Faced By Engineers in India, Mainak Ghosal
India has the largest number of engineering graduates passing out every year when compared to the USA. But does our Engineering profession get recognized in the eyes of law? The answer is NO when compared to our Medical Professionals or Chartered Accountants or Architects. There is the Medical Council of India [1956] to regulate Doctors, the Institute of Chartered Accountants of India [1949] to regulate Chartered Accountants, and the Council of Architecture [1972] to regulate Architects, and all of these professional bodies are protected by statutes or by an act of parliament. In most countries, e.g., Australia, Japan, Canada, Malaysia, New Zealand, Pakistan, Sri Lanka, South Africa, Singapore, Tanzania, USA, UK, etc., professions such as Engineers are invariably governed by an act or law of the Government.

78 ReSmart-15: A Soft Information Gain Based Questionnaire for Early Dementia Detection, Hyeseong Park, Myung Won Raymond Jung, Ji-Hye Kim and Uran Oh
As the number of people affected by dementia increases, there is a need for diagnosing potential symptoms of early dementia, and questionnaires such as the mini-mental state examination (MMSE) are widely used for early dementia detection. To build a more effective questionnaire, we propose ReSmart-15, a dementia detection questionnaire that includes daily behavior-based questions in five categories (i.e., attention, spatial ability, spatiotemporal ability, memory, and thinking ability). To evaluate the effectiveness of each question in detecting early dementia, information gain can be used to rank their contributions. However, the current information gain-based method requires hard classification results such as whether the patient had been diagnosed with early dementia or not. In this paper, we propose a “soft information gain” based ranking system where each patient is diagnosed with an early dementia probability (from 0 to 1), not with a hard decision of early dementia (0 or 1). We conducted an experiment to test the effectiveness of ReSmart-15 compared to MMSE and found that the top 2 questions were from ReSmart-15, and 60 percent of the ReSmart-15 questions were in the top 10. Keywords: Early demantia; Questionnaire; Soft information gain

80 A Naive Bayes Multi-class Weighted Classifier of Internet Packet flows over a MPLS Network, Roland Déguénonvo, Audace AV Dossou-Olory and Max Fréjus O Sanya
Our simulation is based first, on a qualitative approach for the classification of flows and traffic, and next on an experimental approach for the management of data volume on the other hand. The adopted approaches allowed us to get an idea on a NBWM (Naive Bayes Weighted Multi-class) classifier capable to output differentiated service classes in MPLS (Multiple Protocol Label Switching) networks. The classifiers we compared to our benchmark model were thoroughly processed. The accuracy rate of the proposed NBWM (Naïve Bayes Weighted Multiclass) classifier is about 68.75%, which puts it ahead of the other models encoun- tered.

81 Re-examining Design Games from the Perspective of Design Anthropology, Yan Wang
This paper discusses how design games play a role in design anthropology research and serve the operation method of image behavior. By defining the design game in design anthropology, we can solve the following two problems: firstly, pay attention to how to promote group cooperation and help design researchers understand the relationship between image, space and be- havior; secondly, this study helps researchers understand the vague role and cultural cognition of stakeholders in participatory design. In addition, this study designs a set of design game cards, through the extraction, collage, and reorganization of film im- ages, and further changes the observation perspective, once again expanding the game to the field of the art design and design anthropology. The ultimate goal of the research is to explore the research methods in the design process and the training of reconstruction logical thinking. In future work, the design education can use game cards as the carrier to reconstruct the cultural cognitive language.

82 Epistemiology of the South - “Navigating and Traversing the Proverbial Avalanche post PhD in the 21st Century - A Narrative Reflection”, Mfanelo Patrick Ntsobi
Knowledge can be transmitted, facilitated, developed, and produced in a variety of ways through education. As a matter of fact, universities in particular, are defined in terms of knowledge generation. We should not be surprised, then, that discussions about decolonizing (Western) education have expanded to encompass provincializing (Western) epistemology, given the close ties between education and educational institutions and epistemology. This presents a danger as epistemological pathways in- form thinking partners and behavioural dynamics of societies. Deconstructive debate that seeks to discuss educational decolo- niality from the Global South cannot articulate that with the exclusion of southern epistemological position towards reality with through the lens of its inhabitants. This is what confronts the post-doctoral scholar of the Global Centre for Academic Research and South Valley University, as independent entities within the Global South. This narrative reflection provides a baseline for a cogent discourse in favour of deconstruction of southern epistemological trajectory in education and social perspectives. Keywords: Doctoral education; Decoloniality; Social Discourse; Southern Epistemology
83 Students’ experiences in relation to the use of online learning and collaborative technologies during COVID-19 outbreak in South African Universities, Mfanelo Patrick Ntsobi, Paul Singh and Blondel Nyamkure
Student’s experiences on the use of online collaborative technology continues to attract attention of researchers in education and social sciences. Of particular interest is the reliance on technological and digital platforms, using web-based strategies during the outbreak of COVID-19 in institutions of learning. This study used an unlinked, anonymous survey to explicate experiences of students on the use of online technologies during the COVID-19 pandemic in South Africa. Consenting participants constituted a study population that was made up of first year accounting students in a public university in South Africa, drawing a sample of 190 from a population of 371. Using a theory of connectivism, the study found that students were eager and confident that collaborative technology could lead them to pass their examinations even if face-to-face intervention was missing. Collaborative technology consisting of tools such as WhatsApp, Blackboard and Zoom made it easy for them to relate with instructors and fac- ulty who were making efforts to deliver content in a simplified manner. The study further concluded that efforts have to be made to study the benefits of collaborative technology both to learners and faculty at institutions of higher learning.

84 Drones / Unmanned Aerial Vehicles, R Hema
Unmanned aerial vehicles (UAVs), sometimes known as drones, have the highest potential for usage in a variety of applications in the near future. As drone technology advances, these devices will also get more affordable, sophisticated, and useful. An aircraft without a human pilot, flight crew, or passengers is called an Unmanned Aerial Vehicle (UAV), also referred to as a drone. UAVs were initially cre- ated in the 20th century for use in military operations. As control technologies became more affordable and effective, their employment in several non-military applications increased. Devices like transmitters, receivers, and sensors make it possible to control things. It is capable of carrying a lot of weight and flying at vast altitudes. A drone can be used for a variety of tasks, including aerial photography, surveillance, spraying water and pesticides on crops, inspecting fields for water connection leaks, and more.
85 Post Digitization Challenges and Solutions for India Palm Leaf Manuscripts, Nagendra Panini Challa
India is a country with a very deep and significant history and a grand heritage. Its culture and traditions are very unique, varied and celebrated the world over. Each and every district in the country has its own set of heritage structures, traditions and cultural practices. One of the important facets of our heritage is the palm-leaf manuscripts. Our country is home to more than five million palm- leaf manuscripts – the largest collection in the world. The manuscripts cover a variety of subjects - from music, to yoga, languages, art, architecture etc. Their fragile nature makes palm-leaf manuscripts susceptible to damage. It is the duty of our society to safeguard its culture and heritage and pass it on to the next generation. Information and Communication Technologies (ICT) provides us with an array of solutions for data collection, processing and presentation. The use of ICT in the preservation and dissemination of our Culture and Heritage is an area with high potential, and is to be explored in depth, in a domain-specific manner.

89 Promote the Development of New Energy Vehicles and Carbon Neutrality in Beijing, Xinyi Mei, Yuexue Miao, XiaojunJia and Xiguang Zhang
For the further implementation of Jinping Xi’s speech spirit, on the Fifth Plenary Session of the 19th CPC Central Committee. China will accurately grasp the characteristics of the Times in the new stage of development while facing “The overall strategy of the great rejuvenation of the Chinese nation and the great changes unseen in the world in a century”. China will unswervingly implement the new development concept of “innovation, coordination, green, open and sharing”. China will also speed up the construction of domestic and international dual cycle to promote the new development pattern of each other. In particular, we investigated and implemented the target goals and tasks of carbon peak and carbon neutrality set out in the 14th Five-Year Plan. According to the survey, with a population of 1.4 billion and a middle class of 560 million, in 2020,China had 280 million cars and 4.92 million new energy vehicles. In 2021, China had 302 million cars and 7.84 million new energy vehicles. China’s oil industry is 65 percent dependent on foreign investment, and gas-powered vehicles account for one-third of its oil con- sumption. Among them, Beijing has a permanent population of 21.886 million. In 2021, there were 6.143 million civil vehicles, an increase of 140,000, and 507,000 new energy vehicles, an increase of 107,000. According to the 2021 China Urban Transport Report, Beijing’s rush-hour commuter congestion index was 2.04. Beijing’s urban traffic congestion has been normalized. The environmental protection pressure of energy conservation and emission reduction is rather huge for Beijing. Energy consumption, pollution, traffic efficiency, travel safety and other problems are forcing the whole auto industry of Beijing to upgrade. Aiming at these problems, this paper puts forward four suggestions. Keywords: Electric vehicles; Industrial chain; Supply chain security; Carbon neutrality
90 Hysteresis Loop Measurement for Steel Sheet under PWM Excitation Condition, Xinyang Gao, Nana Duan and Shuhong Wang
This article adopts a method of measuring the hysteresis loop of oriented silicon steel sheet under the excitation of pulse width modulation (PWM) signal.

91 Pore Structure and Acoustic Characteristics of Shaximiao Formation in Sichuan Basin Citation: Zhao, Zhao Dan, Zhang Qingxiu, Guo Jingshu, Li Gang and Zeng Shuti
With the deepening of exploration and development, the natural gas development in Sichuan Basin has entered the stage of tight gas exploitation. There are significant differences between tight gas and conventional natural gas resources, which are embodied in more complex pore structure and lithology. These differences make it difficult to predict the “dessert” development area of tight rocks. Therefore, it is necessary to study the pore structure characteristics, petrophysical characteristics and forma- tion fluid of tight sandstones. In this paper, through CT scanning and thin section identification, the characteristics of rock micro pore structure in Qiulin area are found, and the petrophysical characteristics of tight rock reservoirs are found through P-S wave experiments. The research shows that the pores of Shaximiao Formation in Qiulin area are large, with pore diameter distribution of 0.05~0.5mm and the pores are relatively developed, with an average porosity of more than 10%. The study of rock physical properties shows that dense rock Poisson is higher than conventional carbonate rock and shale, and has the characteristics of low acoustic wave velocity and low Young’s modulus.

92 Historic Moments Speak of History - Sort out the Historical Status and Great Significance of the Founding Merits of Qingsanjing in Changqing Oilfield, Sun Jiajun
Why did this voice come so late for the sound of Kei Mitsui?’ There are some objective reasons for this. On the one hand, the 1858 drilling team that undertook the drilling of the Qingsan well and most of its parties were almost 40 years old from the Changqing Oilfield by the reorganization Years, so the people who know the glorious history of Keimitsui are only a very small minority within the scope of the Changqing Oilfield; On the other hand, the important person who came to Qingsanjing to witness the great achievements of Qingsanjing belonged to the old Red Army veteran revolutionary Wang Xing, who left the oil system after serving as the director of the Military Control Commission of the Ministry of Petroleum for a short time, although this per- son was a great hero with legendary experience and major contributions, when he was no longer in an important position in the petroleum system, who cared about the fact that he had made a trip from Beijing to the small place of Zhaogoumen in Huachi County, Gansu Province, for an oil well! Of course, Lao Geming quietly came and left quietly, unwilling to add a simple style of reception affairs to the local government, so that his trip to Huachi failed to leave a historical record in the local area, which was also a reason why Qingsanjing’s meritorious name did not jump up at that time. Then, in 1989, the publication of the Changqing Oilfield Chronicle, The Well was mistakenly identified as a well of discovery, and the superposition effect of the historical phe- nomenon made the name of The Famous Well covered in layer after layer of smoke and dust. Without the eternal perseverance of sitting on the bench for ten years cold and not writing half a sentence in an article, it is very difficult to sort out a relatively clear and clear context for the historical status and significance of the merits of The Founding Father of Kei Mitsui. Penetrating the time and space distance of half a century, it is a major issue to sort out the historical status and significance of Kei Mitsui’s meritorious service. It is necessary to comb through the memories of the parties concerned, to sort them out in reliable historical documents, and to comb through the small place of Zhaogou Gate in Huachi County, the birthplace of Qingsanjing. Who would have thought that this sorting process would take a full twelve years of precious time. What can be comforted is that this mission has finally been completed now.

93 A Collection of Revolutionary Technologies for Low Permeability Cocoon Breaking in Changqing Oilfield, Sun Jiajun
What we want to summarize here is a low permeability oil and gas field. After 50years of polishing, those revolutionary tech- nologies branded with low permeability marks. In terms of its contribution, it is such a technical sequence from one row to six: first, oil and gas exploration technology that infinitely approximates the migration and accumulation law of Ordos hydrocarbon sources; The second is the brand-name, customized and service-oriented drilling fluid completion hydraulic fracturing technolo- gy; Third, natural fractures are not developed, and artificially created fracturing technology for low permeability oil and gas res- ervoirs; Fourth, the advanced water injection and pressure boosting development technology of ultra-low permeability oil fields, which is deficient in nature and then compensated by nature; Fifth, the large-scale cluster well technology that low-permeability oil and gas fields must be developed at low cost; The sixth is the horizontal well technology that allows the longest possible well section to lie flat in the oil and gas reservoir. It is these technologies that have exerted their effects on the low-permeability oil and gas reservoirs, resulting in many changes in the low-permeability oil and gas reservoirs in line with people’s wishes. It is these gratifying changes that converge into a continuous flow of oil and gas in Changqing Oilfield.

94 Experimental Study on Moisture Loss Mechanism in Apples Tissue, Georges El Achkar Bin Liu and Rachid Bennacer
In this paper, the moisture loss mechanism in biological tissue of apples was experimentally investigated in order to under- stand this mechanism and hence to extend their shelf life. An image conversion procedure, based on the use of image processing and AlgoLab Photo Vector softwares, was developed in order to characterise physically the internal porous structure of apples from the core to the skin. Several geometrical and physical parameters of the restructured porous media (porosity, fractal dimen- sion, tortuosity, capillary pressure, permeability) were determined, and a comparison between their trends was carried out and analysed. Besides, a moisture loss model was established and discussed. Keywords: bioproduct; apple; biological tissue; porous media; dehydration; experimentation
95 Numerical Study on Thermohydraulic Characteristics of Reciprocating Room Temperature Active Magnetic Regenerator, Georges El Achkar, B Liu and R Bennacer
In this paper, a thermohydraulic characterisation of a reciprocating room temperature active magnetic regenerator, with gadolinium particles used as a magnetocaloric material and water used as a heat transfer fluid, was numerically carried out. A two-dimensional transient flow model was developed using COMSOL Multiphysics software in order to determine the water flow distribution in two active magnetic regenerators of cross and parallel gadolinium particles distributions for different water inlet velocities of 0.06, 0.08, 0.1 and 0.12 m.s−1. The gadolinium particles have a radius of 1.5 mm and a distance from one another of 0.9 mm. Based on the simulations results of this model, a second two-dimensional transient coupled flow and heat transfer model was then developed using the same software in order to characterise the convective heat transfer in the active magnetic regenerator of cross gadolinium particles distribution for the same water inlet velocities.
