Abstract: Main building blocks of a SAR-ADC are: sample & hold circuit, comparator, timing and logic control which is mainly SAR logic, DAC (Digital to Analog Converter) in the feedback loop of ADC. For low-power applications designer needs to come up with a compromise among speed and resolution. In this...     Read More

Abstract: Fast transportation systems and rapid transit systems are nerves of economic development for any nation. All developed nations have well developed transportation system with efficient traffic control on road, rail, and air. The monitoring and control of city traffic is one of the key issues esp...     Read More

Abstract: Distributed Denial of Service (DDOS) attacks are one of the most widely spread problems faced by most of the Internet Service Providers (ISP’s) today. Mitigation of these attacks has gained utmost importance in the present scenario. A number of mitigation techniques have been proposed by vario...     Read More

Abstract: This paper presents a Genetic Algorithm (GA) based approach for selecting small number of representative features from a large dataset thereby leaving irrelevant features. Fitness function is used to decide the fitness of each individual using k- NN classifier and genetic algorithm. Real dataset...     Read More

Abstract: IN this paper, a new approach to face recognition is presented in which not only a classifier but also a feature space is learned incrementally to adapt to a chunk of training samples. Human face recognition plays a significant role in security applications for access control and real time vid...     Read More

Abstract: The large usage of digital photography, the high performance commodity hardware and low cost efficient image editing software have posed a challenge to check the authenticity of image if produced as a official document. In this paper various image forgery detection methods are mentioned and elab...     Read More

Abstract: In this letter, a fully integrated down-conversion mixer is presented for multiband applications. The receiver front-end consists of a multiband low-noise amplifier (LNA) and a down-conversion mixer. The down-conversion mixer is major responsible for the limited dynamic range in the RF front-en...     Read More

Abstract: This paper addresses solution to the problem of reaching an agreement (consensus) in a distributed system. The aim is to maximise fault tolerance as well as reduce the message exchange overhead. The proposed algorithm uses as few as two rounds of message exchange. This better efficiency is achieved ...     Read More

Abstract: As companies increasingly use virtualized data centers and cloud services, new weaknesses have opened up in enterprise infrastructure. At the same time, denial-of-service attacks (DoS) are moving from brute-force floods of data to more skillful attacks on application infrastructure. The combina...     Read More

Abstract: We are aware that the power limitation is a critical issue for the sensor nodes, so different scheme or algorithm was proposed to implement the routing protocols to expand the minimum power utilize the maximum work [1,2].But it is unfortunate that most of them are not security concerned. As we...     Read More
