    This paper describes the design of an ultra-low-power analog front-end circuitry for a UHF passive RFID transponder. The design includes a voltage multiplier, a voltage regulator, a demodulator, a power-on-reset, a ring oscillator, a matching network and a backscatter modulator. We present a novel charge-pump circuit for improved voltage gain and power efficiency of RFID tags. The charge pump is f... View full abstract»

    Design of leading-one detector (LOD) and leading-one position detector (LOPD) are important as they are used for the normalization process in floating-point multiplication, floating-point addition/subtraction and in logarithmic converters. In this paper, the authors propose various gate-level architectures for LOD and LOPD. The LOD and LOPD circuits are evolved using the evolutionary algorithm (EA... View full abstract»

    (4; 2) compressors seem to be the most popular bit-compressing cells with principal application in multi-operand addition and multiplication hardware. Therefore, performance of (4; 2) compressors is particularly influential in the efficiency of multiplication intensive computations. Realization of these cells is mainly based on XOR/XNOR gates, which are functionally equivalent to three simpler one... View full abstract»

  • A new detection operator for narrow band character extraction in low contrast scenes

    Publication Year: 2013 , Page(s): 117 - 121

    Character detection plays an important role in character recognition systems. In this paper, we propose a new detection operator to extract the characters with approximately equivalent width from a low contrast simple natural scene. Initially, the Canny detector is applied to get the edge map. Afterwards, the distance transformation is performed on the edge map to get the regional maximum pixels (... View full abstract»

    Service discovery is a significant area of research in mobile ad hoc networks, where mobile nodes are allowed to exchange services and utilize each other's services. Furthermore, in ad hoc environments, the service discovery process is enhanced by making use of semantic descriptions of services. Semantic-based user requests are used to carry out discovery process to satisfy the requester's service... View full abstract»

    Video traffic nowadays forms the majority of traffic over the Internet, and is predicted to be the most prevailing traffic type in the coming few years. TCP-Friendly Rate Control (TFRC) is one of the most promising end-to-end congestion control protocols that is intended for unicast playback of Internet streaming applications. This paper presents a new TCP-Friendly congestion control protocol, cal... View full abstract»
