ABSTRACT. Machine learning and artificial intelligence will become defacto in many systems ranging from small microcontroller based devices to large complex server based systems released over the next few years. With these new trends, it is important to embrace the change needed from an engineering development perspective because developers need to consider adding machine learning components into the development flow. Similar to the need for DevOps for scale, engineers now need to consider MLOps into their development flow. On top of machine learning, connectivity to cloud services is becoming the norm of many edge devices to take advantage of many available cloud services. Engineers need to consider the different services offered by cloud service providers to make the concept of cloud to edge as seamless as possible and achieve scale. This keynote will provide an overview of the key development methodologies that different companies need to consider when building devices with machine learning capabilities and cloud service providers.

ABSTRACT. One of the most important requirements to be consider when designing a converter to convert the supply from an Alternating Current to Direct Current for DC loads to improve the power quality enhancement at the input side. In this paper, input side, the applied voltage is boosted from 230rms volts value is given to obtain the desired output value as 400v with the help of a Boost Converter. Since it effectively overcomes the effects of parasitic elements and significantly increases the output voltage. To achieve this, the voltage-lift technique is a common method that is commonly used in electronic circuit designs. As a result, dc/dc converters can convert a lower input voltage to a higher output voltage while maintaining high power efficiency and density. However, maintaining power factor at input side closer to unity is a big problem. Owing to these, power quality is improved by improving the power factor with hysteresis current control strategy and also, incorporating outer voltage control technique. As this model is operating on universal supply is converted into dc voltage with DBR (Diode Bridge Rectifier) conversion is up lifted to the desired voltage of a three – phase dc motor value used for industrial applications such as hydraulic pump operations to pump the water at constant speed drive and chemical injection pump applications.

ABSTRACT. Today, multilevel converters are considered the most advanced power conversion devices for high-quality applications. Because of the redundancy and modular structure, cascaded h-bridge multilevel inverters have been used in various industrial applications. Depending on the application and the multilevel inverter, many different modulation algorithms have been created or changed. Each one has its own pros and cons. In this paper, the modulation techniques Nearest Vector Control (NVC) and Nearest Level Control (NLC) have been implemented for three phase five level cascade h-bridge multilevel inverter in simulation with the help of MATLAB/Simulink. The NVC and NLC are compared with their total harmonic distortion factor in the output voltage. Using the WAVECT controller in an experimental setup, the results of the simulations are tested. NLC provides a better total harmonic distortion factor as compared with NVC.

ABSTRACT. Communication over power lines do not need any additional infrastructure. However, this technology is still in its naïve stage despite inventing it a century ago. In this paper, an attempt is made to understand the prospects of PLC and the role it can play in conjunction with future technologies. For this, it is important to understand the merits, limitations and applications of PLC. The penetration of PLC is better than wireless communication in rural areas and concrete structures. In this paper, the applicability of PLC in identifying the cable faults is studied. The cable faults are monitored using channel modelling technique and experimental analysis

ABSTRACT. An expeditious growth in population, urbanization and industrialization demands for non-polluted air for better life standards in smart cities, metro cities and urban areas. A move towards better life standards is to encourage green transportation for the needs of future generations. One such solution is to use electric vehicles (EVs), but still 3/4th of today’s transportation had relying on petrol and their by-products-based engines due to lack of awareness, fire accidents, storage limitation, charging times and lack of charging infrastructure. So, to address one of the said limitations proposed a compact, efficient, and simple novel DC-DC boost converter for medium gain applications. It is first of its kind uses one controlled switch and two uncontrolled switches along with coupled inductor which also made the proposed converter to be the potential converter stage in the onboard charger, electrical drive system and fast charging infrastructure. A mathematical analysis carried out to find values inductance, capacitance, and duty cycle to get the required gain. The CI based converter is simulated in MATLAB Simulink environment under open loop and closed loop.

ABSTRACT. A microgrid is an independent energy system comprising loads, distribution generators, and renewable sources of energy like a solar cell or wind turbine. Power generation becomes a tedious task due to the dynamic nature of the load as optimal scheduling is required to keep the generators within operational limits. Further, cost minimization is the primary objective in power generation that adds the value of optimal scheduling. Due to the recent upsurge in industries and advancement in transportation, environmental emission has increased in a drastic way. Therefore, a compromised solution is required. This paper uses a Class Topper Optimization (CTO) algorithm to solve the economic load dispatch (ELD), economic emission dispatch (ECD), and price penalty factor (PPF) based on the combined economic and emission dispatch (CEED) problem for microgrid system.

ABSTRACT. Twenty first century is characterized by the expansion of wisdom and knowledge. The Responsibility of growth and success of any educational institutes lies on the shoulders of the committed, proficient and enthusiastic faculty working in the education institutes. Organizational commitment involves the loyalty of the individuals toward their organization, employee’s inclination to make an attempt on behalf of the organization. The purpose of the study is to understand the impact of O.C. components on the teachers of higher education. To analyze the impact of demographic factors on three components of O.C. on teachers of higher education, secondary data was referred from high index (SCOPUS, W.O.S. etc.) journals. Primary data was collected using goggle form. A modified structured questionnaire was used (Bateman, Organ 1983). Three components viz. Affective, Continuance and Normative were considered.

ABSTRACT. William Spady proposed Outcome Based Education (OBE) during 90's to bring more focus in the formal education. Moving from teacher centric approach to learner centric approach, aligning curriculum, teaching learning activities, outcome-based assessment methods, aiding the learner to exhibit higher order thinking skills are the list of few best practices implemented through OBE. OBE in helps learners to understand Knowledge, skills and behavioral attributes that they can demonstrate at the end of the programs and provide over all guidelines to the teachers on the list of courses, concepts, teaching pedagogy and assessment methods to follow to achieve the desired outcomes. Measuring the success of Implementing outcome-based education helps to improve the overall quality of teaching learning process. OBE is measured by measuring program education objectives, program outcomes and course outcomes which can be quantified through assessment methods. Mapping the course outcomes with program outcomes and program educational objectives is one of the major steps in measuring the OBE. As the program outcomes statements are written at very generic level, in general it would be difficulty to map the course outcomes with the program outcomes. To simplify this process and as recommended by AICTE Exam reform policy, the researchers in this article has introduced the concept of competency and attempted to link the course outcomes with the program outcome through competency and performance indicators. A frame work and guideline to measure the attainment of course outcome through competency and performance indicators is discussed by illustrating a Practical-based course.

ABSTRACT. Web application security is the most important area when it comes to developing a web application. Many web applications having vulnerabilities due to poor implementation of security measures. These web applications will be deployed without fixing the vulnerabilities thus becomes vulnerable to many cyber-attacks. Simple attacks like brute-force and NoSQL injection could give unauthorized access to the user accounts. This leads to user privacy issues which could create huge loss to the organizations. These vulnerabilities can be fixed by implementing the necessary security measures while developing the web application. OWASP (Open Web Application Security Project) is a non-profit organization which gives the severity, impact and prevention methods about Top 10 vulnerabilities in web applications. This research deals with the implementation of best security practices for Node.js web applications in detail. This research paper proposes the security mechanisms for attacks related to front-end, middleware and backend web development using OWASP suggestions. The main focus of this research paper is on prevention of Denial-of-service attack, Brute force attack, NoSQL injection attack and Unrestricted file upload vulnerability. The proposed prevention methods are implemented in a web application to test the defensive mechanisms against the mentioned vulnerabilities.

ABSTRACT. The increased use of the internet has presented the most significant challenge to the digital world's security. Malicious URLs are the most common way for people to engage in phishing schemes and spread viruses like trojans and worms. Various dangerous URLs attempt to obtain user information by distributing different harmful malware. End-users can be susceptible if a genuine user is unable to recognize and remove fraudulent URLs. Attackers can potentially acquire unauthorized access to user data by using malicious URLs. As a result, identifying countermeasures to halt such operations using new and advanced technology is a critical step One of its most effective methods has been thought to be based on ML approaches for correctly identifying a URL as malicious or benign. The project's main goal is to deploy the system in a way that is both efficient and accuracy.

ABSTRACT. To manufacture a precise mechanical device, design plays a crucial part with the materials employed. Because any mechanical system's output is determined by how well its mechanical components are built or designed for large-scale production. In this paper, a mechanical model is carried out for optimal designing of the Plate-fin heat exchangers (PFHE) to minimise three objective functions i.e. total area of heat transferred, total pressure loss or drop, and total annual cost, in order to solve design challenges in mechanical devices and improve production. In this case, the heat exchanger pressure loss, annual cost, and efficacy are estimated using the $\varepsilon$ -NTU approach. Seven design variables are considered as decision variables: flow length of both cold and hot stream, height of fin, no-flow length, fin-pitch, and offset length of fin. This paper offers the Kho-Kho Optimizer(KKO), a meta-heuristic, inspired by Khoko's game strategy to resolve the issues for better performance. The findings obtained utilising the KKO approach are compared to those obtained using other optimization procedures with original preliminary design variables in this study. Finally, when it comes to addressing a mechanical problem, the KKO algorithm surpasses several existing meta-heuristic optimization algorithms.

ABSTRACT. Topology optimization (TO) and 3D printing are the precocious methodologies which are integrated to produce light-weight structures with supercilious performance within design constraints of the structures. This research article discusses, the TO approach is used to determine the aircraft landing door bracket's optimum shape & size under various loads. The complicated optimised shape, which is challenging to build through convectional manufacturing process, is then created using 3D printing technique. Since from many years TO & 3D printing have been performed separately, hence integrating these two techniques brings symbiosis results of obtaining light weight and complex geometric components. This article focuses on topology optimized approach by considering overhang constraint to fabricate a light weight aircraft landing door bracket through metal 3D printing technique using Selective laser melting (SLM )process. Altair solid-thinking inspire and optisturct solver are used for this work. This article mainly focuses on shape optimization, mass reduction and to produce light weight bracket by 3D printing where the mass is reduced by about 52.27% without compromising structural and functional performance of the bracket. The obtained results indicate that, when 3D printing is taken into account, topology optimization is a viable way of minimizing product weight while retaining design standards.
