Suitability of Various Low Power Strategies for SRAM Design: A Survey
Abstract: In very high performance system on chip, static power dissipation plays a dominant role compared to dynamic component and it increases with technology scaling. Scaling of bulk MOSFET faces more and more challenges at 45 nm technology or below by producing short channel effect (SCE) which leads to increase in leakage current. An obstacle with bulk MOSFET at 45 nm or below gate length includes SCE, subthreshold leakage and gate …

Nanostructured Cr-WS2 Solid Lubricant Coating for Space Applications
Abstract: Abstract Tungsten disulphide (WS2) is one of the widely used intrinsic low friction materials, which is commonly used in the form of coating. WS2 offers very low coefficient of friction only in non humid conditions. Presence of humidity destroys this property and restricts its utility. Modifying the structure of WS2 by adding certain metals helps in overcoming this limitation and in addition improves the mechanical properties. Further, deposition technique and …

Enhancing Resolution of Artifact Image using AR-CNN and SRGAN
Abstract: Abstract The super-resolution strategy recreates a higher-resolution image or arrangement from the observed low resolutions (LR) images. As super-resolution has been created for over three decades, both multi-casing and single-outline super-resolution has critical applications in our everyday life. Existing super-resolution strategies have a few constraints. The artifact is additionally an issue in compression of an image. With artifacts, the high-resolution image is most noticeably terrible to see. In this paper, …
