In two recent contributions, minimization of number of adders in realization of digital finite impulse response (FIR) filter has been discussed. The proposed method extends the concept of these techniques to further reduce the requirement of adders in FIR filter for different applications. This paper is based on merging of concepts involved in vertical and horizontal common sub-expression elimination...
This paper proposes an accurate and efficient strategy for identification of Hammerstein model based nonlinear systems using Craziness based Particle Swarm Optimization (CRPSO) algorithm. The closeness of estimation of the proposed CRPSO based identification scheme has been justified with the optimal value of MSE and the corresponding comparative study with the other techniques reported in earlier...
With increasing complexity of electronic circuits, the design and optimization of electronic circuit needs to be automated with high degree of reliability and accuracy. In order to optimize hardware requirement of digital combinational circuits, evolutionary and innovative techniques need to be enforced at various levels such as gate level and device level. This paper presents the use of one of the...
In this paper, a meta-heuristic algorithm known as artificial bee colony (ABC) algorithm is employed for the design of digital infinite impulse response (IIR) filter based on nonlinear minimization of mean square error (MSE) between the ideal and desired responses of the filter. In this method, stability of IIR filter during design is assured by using lattice structure as it makes easy to maintain...
An Electrocardiogram (ECG) signal compression technique is proposed using compressed sensing/sampling technique based on Block sparse Bayesian learning (BSBL) algorithm.

A simple efficient iterative technique for the design of non-uniform filter banks (NUFB) proposed by Soni et al is examined and improved by designing the prototype filters using constrained equiripple finite impulse response (FIR) technique. In this method, instead of optimizing the cut-off frequency, the passband edge frequency (ωP) is varied iteratively in order to adjust the filter coefficients...
3D IC technology has demonstrated significant performance and power gains over 2D. However, for technology to be viable yield should be increased. Testing a complete 3D IC after stacking leads to an exponential decay in yield. Pre-bond tests are required to insure correct functionality of the die. In this work we propose a hypergraph based biased netlist partitioning scheme scheme for pre-bond testing...
In this paper, we present a novel Expectation Maximization (EM) algorithm for automatic color image inpainting using a new discrete multi scale directional sparse representation called the Discrete Shearlet Transform (DST). It is now acknowledged that the traditional wavelets are not very effective when dealing the multi dimensional signals having distributed discontinuities such as edges. To achieve...

We tested the efficacy of results in RGB, YCbCr, HSV and NTSC using the Rand's Index. The work is useful in telepathology applications and...
Digital Signal Processing (DSP) system involves a wide spectrum of DSP algorithms for its realization and is often accelerated by use of novel VLSI design techniques.

Mutation Testing is used as fault-based testing to overcome limitations of other testing approaches but it is recognized as expensive process. In mutation testing, a good test case is one that kills one or more mutants, by producing different mutant output from the original program. Evolutionary algorithms have been proved its suitability for reducing the cost of data generation in different testing...
Cluster analysis, a set of tools for building groups from multivariate data objects is extensively applied in many fields. One of the most widely used classical approaches of clustering is K-means algorithm. Kohonen's Self Organizing map is a neural network clustering methodology that maps an n-dimensional input data to a lower dimensional output map. In this study, we have compared K-means algorithm...
We propose partial and full link reversal algorithms to bypass voids during geographic routing over duty-cycled wireless sensor networks. We propose a distributed approach that is oblivious to one-hop neighbor information. Upon termination of the algorithm, the resulting network is guaranteed to be destination-oriented. Further, to reduce the delays incurred under reactive link reversal, we propose...

The proposed algorithm is based on the optimum value of passband edge frequency (??p) that is found by approximately satisfying the magnitude response condition of the prototype filter at frequency (??=0.5??). In this algorithm, passband edge frequency is optimized. Performances...

Kinematic measurements using active markers are well known methods. This paper aims at the development of an image analysis algorithm and LabVIEW based software tool for active marker based gait analysis. Active markers in the form of light-emitting diodes (LEDs) were positioned at anatomical landmarks to measure the coordinated kinematics of human joints.
In macrocell based SoC design, a routing plan to decongest top channel is an important step during floor planning. While previous approaches attempt at reducing congestion of chip as a whole, there is no attempt to specifically decongest top channel. We present an algorithmic approach to decongest top channel by using very few feedthroughs. Results show that compared to conventional methods, we can...

The performance of this algorithm is evaluated in terms of computational...
