ABSTRACT: Underwater captured images often suffer from the extant literature may be broadly classified into two groups based on the use of the underwater picture generation model: underwater image enhancement and restoration. Objective evaluations have demonstrated that these existing methods may perform well, but they fall short in accounting for multiple degradation and the loss of crucial data the conditions in which they can be used. Restoration algorithms are heavily reliant on accurate previous assumptions and need more prior knowledge about the imaging circumstances. But unlike in the atmosphere, most scenarios in the complex and dynamic undersea world are hard to generalize based on a priori assumptions. So, it could lead to low resilience and subpar outcomes.....

ABSTRACT: Skin diseases rate has been increasing for past few decades. Psoriasis is chronic inflammatory skin disease which affects more thgan 3% of population. One of the risk factor in skin cancer is unprotected exposer to UV radiation, which causes various skin diseases. For early diagnosis of skin cancer, psoriasis and dermatophytosis and increases chance for cure significantly. Therefore proposed system used for early prevention and detection named a Image analysis system to detects skin diseases. The image analysis technique where user will able to take skin images of different mole type or rashes type. System will process and analyse the images, which provide notification to user you need medical help. This system provides automatic skin diseases prevention and detection.

ABSTRACT: In this paper, we propose a new paradigm for clock distribution that uses current, rather than voltage, to distribute a global clock signal with reduced power consumption. The Current-mode (CM) signaling can be used for one-to-many clock distribution network. To accomplish this, we create a new high-performance current-mode pulsed flip-flop with enable (CMPFFE) using Tanner tool in 180nm CMOS technology. When the CMPFFE is combined with a CM transmitter, the first CM clock distribution network exhibits 32% lower average power compared to traditional.....
