A HR (High Resolution) video frame may be created from a set of LR (Low Resolution) video frames using a process called Video Super Resolution (VSR). Deep Learning (DL) techniques have surpassed conventional techniques in terms of efficiency. To achieve video super-resolution, the inter-frame information must be extracted. The numerous categories for possible deep learning techniques include methods

Predictive analysis of Low power DC loads in Residential Buildings IOP Conf. Ser. Mater. Sci. Eng. Pub Date : 2023-12-01 BA Satish, P Usha
There has been a constant rise in use of loads powered from direct current (DC) among the residential loads. In the traditional Alternating Current (AC) grid voltage undergoes conversion multiple times before it reaches the loads requiring DC, which leads to substantial power loss in the converters. Implementation of a DC grid in the residential buildings can reduce the losses caused due to the conversions

Maximum Torque per Ampere Technique for Switched Reluctance Motor Drive IOP Conf. Ser. Mater. Sci. Eng. Pub Date : 2023-12-01 Muhammed A Ibrahim, Ahmed Nasser B. Alsammak
Numerous researchers have investigated switched reluctance motors (SRMs) as a competitor to other electrical motors for usage in electric and hybrid vehicle appliances. SRMs are fault-tolerant and have a broad operating speed range. However, they have numerous drawbacks, such as high nonlinearity in machine models, complex control, and torque ripple. This study aims to improve the SRM drive system
