Any high frequency Induction heating system while undergoing through very high frequency switching operations, produces Electromagnetic Interference (EMI) noises or very high frequency harmonics within the system. These high frequency EMI noises conductively propagate towards the input AC source and distort the sinusoidal input AC current and make it non-sinusoidal. The desired performance from the induction heating cannot be anticipated. As such, it is inevitable to eliminate such EMI noises from the input AC source current to get the desired performance. Here, a specially designed ring type LC low pass passive filter is proposed which can accomplish to suppress these high frequency EMI noises up to satisfactory level and can restore the sinusoidal shape in the input AC source current waveform and thus improves the power quality of the AC supply for the induction heating system. The impact of the induction heating system without and with incorporating the proposed filter will be compared in this study.

The epidemic COVID-19 has forcibly transformed the manner of teaching and learning in India's higher education from face-to-face to online, resulting in new experiences and practices for many professors and students. In this context, this research examines the benefits, problems, and tactics of online and offline education in India's higher education during and after COVID-19. The study found that online education is beneficial in terms of time management skills, as well as more freedom for professors and students. However, obtaining reliable internet access at work is one of the most difficult tasks. According to the findings, practitioners who want to participate in online education must be technologically proficient and computer literate. In the context of India, only online teaching and learning cannot be effective, hence blended learning is a preferable alternative in terms of technical education. According to the conclusions of the study, online education can be a viable alternative to traditional education. Thus, in environments such as India, a hybrid approach would make the educational process more effective and successful.

Forest is a major part of the global, ecological, environmental, and recreational system. It has a huge impact on amount of greenhouse gases, atmospheric carbon absorption, and reduction of soil erosion. It directly modulates the temperature and regulate amount and nature of rainwater. To a large extent, forest fire is one of the most dangerous natural hazards that occur in practically in all countries worldwide affecting physical, biological, and environmental consequences. An advanced technology, Wireless Sensor Network (WSN), is nowadays getting more importance and has started application in forest fire detection. The Wireless nodes integrate on the same PCB, the sensors, the data processing, the wireless transceiver, and they all run by the same source- batteries. Unlike cell phones, WSN do not require recharging periodically. The sensors used here, are device for sensing their environment and computing data. The sensors sense physical parameters such as the temperature, pressure, and humidity, as well as chemical parameters such as Carbon Monoxide (CO), Carbon Dioxide (CO2) and Nitrogen Dioxide (NO2). The sensors operate in a self-healing and self-organising wireless networking environment.

To solve the problem of unreasonable task allocation in WSAN, which leads to uneven energy consumption of actuators and too long task execution time, a task allocation algorithm based on auction is proposed. Task decomposition model, task efficiency model and task allocation model were established. The auction actuator node decomposes the task into a plurality of task elements according to the task decomposition model; The actuator node inputs the task element into the task efficiency model, and calculates the efficiency of the completed task element; The auction actuator node comprehensively selects the best task allocation scheme according to the task allocation model. Simulation results show that compared with other algorithms, this algorithm reduces the task completion time, balances the energy consumption of actuators and prolongs the network life.

Structures founded on soft ground are likely to be exposed to disastrous consequences due to possible undrained failure or excessive settlement unless proper ground improvement is undertaken. Soft soil improvement by granular reinforcement has numerous benefits in terms of strength and stiffness as well as accelerated consolidation. Foundation soil supporting transport infrastructure are in addition subjected to cyclic loading initiated by traffic movement. This paper presents the load-transfer and consolidation characteristics relevant to stone column reinforced soft ground supporting transport infrastructure.

An extraordinary methodology is needed to satisfy the need of financially suitable solar cell technology. By utilizing ongoing advances in semiconductor nanocrystal research, we have now invented a one-coat solar paint for planning quantum dot solar cell. The conversion behavior of this semiconductor film electrode was assessed in a photo electrochemical cell comprising of graphene–Cu2S counter electrode and sulfide/polysulfide redox couple. The efficiency of Power conversion exceeding 1% has been observed for solar cells developed utilizing the straightforward traditional paint brush approach under ambient conditions. Though further upgrades are important to develop procedures for huge region, all solid state devices, this primary effort to make solar paint offers the benefits of simple design and financially suitable for next generation solar cells. The solar paint has shown the extensive possibility because of its flexibility, tunable size characteristics, and economically profitable nature in manufacturing. However, there is as yet a requirement for the improvement in the power transformation efficiencies of these paints, which elaborates further research to make the optimum materials for the paint. The point of this study is to discover the materials for the paint, which would have high electrical, thermal conductivities and higher efficiencies.

Risk management in the construction industry is regarded as an important issue for the healthy development of society. In terms of the risk management process, over detailed process would be remarkably time consuming which also can be a burden of the project. the balance between the prescriptiveness and the flexibility of risk process can be considered as the vital factor for a effective risk management framework. However, flexibility is not well valued in the risk management process of many construction projects. An ideal risk management process should include both the clear prescriptiveness and the flexibility in order to minimize the negative influence of risks in construction project as well as to shorten period of process planning.
