Low power, high resolution and high-speed ADCs are becoming increasingly important with advancements in portable electronics, from mobile phones and pagers to CD players and MP3 players. This is certainly not feasible on a handheld device which is why new ADC techniques must be developed. They are becoming increasingly attractive to major data converter manufacturers and their designers because pipeline ADCs provide an optimal balance of scale, speed, resolution, power dissipation and analogue design effort. Because of latency and errors in comparators & gain stages in pipelined ADCs, the need arises for digital error correction mechanism. The digital error correction logic will be implemented for 8-bit ADC using 1.5 bits per stage. While designing we are considering important parameters of CMOS like propagation delay performance and power dissipation. The VLSI realization of digital arithmetic is implemented using TANNER EDA software tool using 0.18µm CMOS process.
Nowadays, digital watermark protects intellectual property in the digital world. In this article, a new singular value decomposition (SVD) based robust unsighted video watermarking technique is used for protection of copyright or owns individual work. The Singular Value Decomposition is used in this method to embed the information in a video file. In the embedded process the information generally referred to as watermark, which is of the form either audio, text, video, or any binary image or digital image. The embedded information can be identified in this process without considering the mechanisms of the original video, or any other knowledge about the encoded video ‘s main singular values. Singular value decomposition is used in embedding the information as well as retrieving the information from the embedded watermarked video. SVD based robust unsighted video technique shows that it bears required robustness on various attacks like MPEG-2 compressed video, median filtered, small rescaled, and rotational videos. In the experimental result, it is noticed that the unsighted video watermarking technique has visible quality and robustness for various attacks. In which watermark is installed in uniquely chose particular estimations of the video, and the first request can be kept up to recovering the data in our method and it has been indicated roust to different attacks.
Security has become an immense issue wherever all through the world. Concerning human security, the proposed structure can be applied to make it powerfully astute, reasonably secure, and mechanized. Utilizing two sensors bend and pyroelectric infrared the structure was made both really and therefore began. Considering the sensor, the structure turns ON and detects the difficulty area. By at that point, the district is sent to some picked numbers correspondingly as spared in the server. This work joins information assortment by utilizing sensors. To transmit to proliferate together server and move to the site Raspberry and GSM are utilized. Using this structure, individuals of any age can be profited. The structure can be revived and enhanced by further increases of highlights. Unequivocally when a human will reshape his stable finger following to conflicting with any sort of hazard, the resister estimation of twist will be changed and the structure will be on. By at that point, not just SMS including locale will be sent to the predetermined numbers yet likewise, it will be moved and spared as still pictures to the site.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
