The main goal of the present paper is to solve structural engineering design optimization problems with nonlinear resource constraints. Real world problems in engineering domain are generally large scale or nonlinear or constrained optimization problems. Since heuristic methods are powerful than the traditional numerical methods, as they don’t requires the(More)
A new implementation for decimal floating-point (DFP) division is introduced. The algorithm is based on high-radix SRT division1 with the recurrence in a new decimal signed-digit format. Quotient digits are selected using comparison multiples, where the magnitude of the quotient digit is calculated by comparing the truncated partial remainder with limited(More)
The design and implementation of a double precision floating-point IEEE-754 standard adder is described which uses “flagged prefix addition” to merge rounding with the significand addition. The floating-point adder is implemented in 0:5 m CMOS, measures 1:8mm2, has a 3-cycle latency and implements all rounding modes. A modified version of this(More)
In this paper, we present a hand and face segmentation algorithm using motion and color cues. The algorithm is proposed for the content based representation of sign language image sequences, where the hands and face constitute a video object. Our hand and face segmentation algorithm consists of three stages, namely color segmentation, temporal segmentation,(More)
This paper is concerned with the quantized control design problem for a class of semi-Markovian jump systems with repeated scalar nonlinearities. A semiMarkovian system of this kind has been transformed into an associated Markovian system via a supplementary variable technique and a plant transformation. A sufficient condition for associated Markovian jump(More)
