ABSTRACT: Cotton wool spots are retinal lesions which appear as yellowish or whitish patches with not so well defined edges. Cotton wool spots are closely associated with Hypertensive Retinopathy. Hypertensive Retinopathy is a disturbance in the retina of the eye caused by high blood pressure. Common symptoms of hypertensive retinopathy are arteriolar narrowing, retinal hemorrhages and cotton wool spots. Early diagnosis of hypertensive retinopathy is possible for prevention and accurate treatment. This paper presents an exhaustive review of the various latest trends to detect Hypertensive Retinopathy condition based on computer aided diagnosis screening systems to automated.........

ABSTRACT: Semiconductor memories are a vital component of essentially any state of the art digital circuits. One among them is the Static Random Access Memory (SRAM). The dynamic power consumption contributes to about 80% of the total power consumption. In this paper a novel 4T asymmetric SRAM Cell is proposed which has reduced the dynamic power consumption by 98.58% and area occupied by 30.86% when compared to one of the existing 4T SRAM Cells. This cell is designed using 45nm technology.
Keywords: 45nm technology, 4T SRAM cell, Reduced area occupancy, Dynamic power consumption, Semiconductor memories
