Given the dependence of today's business systems on a network of computers and servers, the need for security is paramount. Furthermore, with the ever evolving nature of business, and the associated technology for supporting it, requirements for security are also evolving. Computers cannot protect information automatically. To guard information residing on the computers, security services and related...
DNA computing utilizes the properties of DNA for performing the computations. The computations include arithmetic and logical operations. In this paper, we describe a procedure for multiplication of a pair of two binary numbers. The procedure mainly consist of bit-shift and addition operations that depends on the bit position of 1's in the multiplier and finally addition operations which take place...
The use of Power System Stabilizers (PSS) to improve the dynamic stability of power system is not a new idea. Present day complexity in power system demands PSS must be robust enough to ensure adequate system performance over a wide range of system operating conditions to come out from the problem of oscillatory instability. H2 and H∞ Norm based robust control techniques have now been developed and...
HIV infection is one of the major health problems in today's world, especially in a developing country like India. The impact of HIV on the pediatric population is no less dreadful. Pediatric HIV is a subset of HIV which requires special attention. Efficient information management is one of the key issues in pediatric HIV treatment. Electronic health record (EHR) plays an important role in patient...
MILSA (Mobility and Multihoming supporting Identifier Locator Split Architecture) is a new architecture to address the naming, addressing, and routing challenges in the current Internet. It separates the identifier (ID) from locator, separates control from data delivery, and provides comprehensive benefits in routing scalability, mobility and multihoming, traffic engineering, renumbering, and policy...
Passive RFID application is often used in back scatter mode where a weak reflected signal is relied upon by reader systems. This limits the application of the technology as the reader and tag distance is constrained. This paper presents a passive design where planar capacitors are used to locally store charges to power a tag based on newer CMOS technology. In this paper BSIM4 transistor model based...
Image authentication has achieved a sharp attention now a day due to broad availability of Internet services. Maldistribution and illegal copying of image, volatiles the authenticity of image-ownership. In this regard we have already proposed different fragile color image watermarking frameworks for embedding a color watermark within a color host image. In current communication we are proposing technique...
Acquiring and reconstructing images from a positron emission tomograph (PET) system usually involves several independent processing tasks. These tasks range from the actual acquisition of the analog detector signals to the final image reconstruction which may also consider additional information from other imaging modalities. To compensate the inevitable variations arising from the analog detector...
The COMPASS experiment (COmpact Muon Proton Apparatus for Structure and Spectroscopy) is a fixed target experiment located at the CERN Super Proton Synchrotron. The physics program is focused on the study of hadron structure and hadron spectroscopy with high intensity muon and hadron beams, up to 160 GeV/c for muons and 190 GeV/c for hadrons respectively. To allow the tracking of charged particles...
The PANDA experiment at the new FAIR facility in Darmstadt, Germany, will be investigating unresolved questions of non-perturbative QCD. The experiment is designed to make use of internal targets in the p storage ring HESR (design luminosity: 2 . 1032 cm-2 s-1, pp-annihilation rate: 2 . 107 s-1), requiring continuous operation of all detectors. One option for its central tracking unit is a Time Projection...
The PANDA data acquisition system will operate in trigger-less mode and collect about 100 GBytes of data per second from more than a thousand front-end modules. The information from all detectors is combined into data blocks, every block corresponds to 500 microseconds of beam. The SODA (Synchronization Of Data Acquisition) project aims to develop a versatile optical network system which is, first...
Emerging nanoscale devices hold tremendous potential in terms of integration density, low power operation and switching speed. Unlike CMOS devices, however, majority of these devices are not suitable for implementing cascaded, irregular logic structure. On the other hand, dense and periodic structures of most emerging nanodevices as well as their bi-stable nature make them amenable to large high-density...
MILSA (Mobility and Multihoming supporting Identifier Locator Split Architecture) has been proposed to address the naming and addressing challenges for NGI (next generation Internet), we present several design enhancements for MILSA which include a hybrid architectural design that combines "core-edge separation approach" and "split approach", a security-enabled and logically oriented...
Summary form only given. It is known that in the human immunodeficiency virus (HIV) genome regions responsible for interactions with the host's immune system, namely, cytotoxic T-lymphocyte (CTL) epitopes, tend to be clustered together, sometimes found in more conserved parts of genome. On the other hand, more variable regions tend to have lower density of CTL epitopes. Furthermore, high recombination...
In order to meet the increasing demands of content dissemination in Internet, we propose a novel architecture for the future Internet called cache-and-forward (CNF), which transports content as "packages" in a hop-by-hop manner towards the destination, instead of transporting a stream of fragmented packets along an established TCP/IP connection. In this paper, we discuss how the CNF network...
The effect of post deposition hydrogen plasma treatment on microstructural, optical and transport properties of hydrogenated nanocrystalline silicon (nc-Si:H) have been investigated. Nc-Si:H thin film were deposited on glass substrate with 33% hydrogen dilution at 200??C using reactive RF sputtering. Thin films of nc-Si:H were treated with hydrogen plasma with various plasma power densities (0.1 -...
Easy availability of internet, together with relatively inexpensive digital recording and storage peripherals has created an era where duplication, unauthorized use and maldistribution of digital content has become easier. To prevent unauthorized use, misappropriation, misrepresentation; authentication of multimedia contents achieved a broad attention in recent days. In this regard we've already introduced...
Power consumption in VLSI circuits is currently a major issue in the semiconductor industry. Power is a first order design constraint in many applications. However, a growing class of applications need extreme low power but do not need high speed. Sub-threshold circuit design can be used for these applications. Unfortunately, sub-threshold circuits exhibit an exponential sensitivity to process, voltage...
In this paper an automatic person identification algorithm is proposed based on retina pattern recognition. Our proposed method follows the steps firstly reference point detection to compensate the translational and rotational displacements, secondly blood vessel segmentation to identify blood vessel intersection points properly and finally matching the intersection points. The maximum principal curvature...
Electromagnetic fields due to an earthquake have been studied in this presentation through some model calculations. The expressions of the variation of electron concentration and electron temperature as the ionospheric precursors of an earthquake have been deduced in this presentation through quasihydrodynamic formulations. The outcome of the analyses of electromagnetic emissions recorded by VLF receivers...
