Numerous techniques abound in the domain of wireless power transfer technology. The current paper carries out a brief review of the most salient concepts, with a special focus on far-field techniques.

Therefore, it would be of great advantage to have a checking and reporting system to detect problems in the early stages so that they can be fixed and both damage and cost can be reduced. The current paper proposes a system to enable condition monitoring of transformer oil using IOT, with an option to generate conditional alert. Wireless Sensor Networks and a Raspberry Pi board is used to monitor the oil using the RF data encountered and alert notifications are sent via push messages.

The present paper deals with a simple machine learning based approach, using regression, for accurate prediction of energy consumption using the fossil fuel and energy consumption data of India as a representative country.

The two-step impedance matching technique has been compared to its six-step variant, by comparing the impedance variation from input to output section in both cases, to enable optimization of power transfer and reduction of standing-wave formation due to significant variation in impedance between two successive sections, which is significant in case of two-step impedance matching by two quarter-wave sections.

For improvement of parameters such as reduction of waiting time in queue and turnaround time, a version of FCFS is developed with a dynamic time slice allocation technique based on job length. The same dynamic time slice allocation technique is used to improve the standard preemptive round-robin priority-based job scheduling technique. Finally, this paper endeavours to attempt a comparative study between the FCFS job scheduling technique with dynamic time slice allocation, and the pre-emptive priority-based job scheduling technique with dynamic time slice allocation, both of which offer better performances than their standard static time slice allocation-based variants.
