Online handwriting recognition is gaining more and more interest as there is increase of pen computing applications and new pen input devices. The main reason behind this is the easy availability of pen computing devices due to the advances in the technology. The recognition of Devnagari characters is different from western handwriting recognition and poses a special challenge. The objective of this...
An attempt has been made in the paper to find globally optimal cluster centers for remote-sensed images with the proposed Rapid Genetic k-Means algorithm. The idea is to avoid the expensive crossover or fitness to produce valid clusters in pure GA and to improve the convergence time. The drawback of using pure GA in the problem is the usage of an expensive crossover or fitness to produce valid clusters...
Bitrate adaptation and higher compression ratio are the major issues in world of Video compression. H.264 is the latest standard for video compression with high flexibility in compression ratio, quality of video and rate adaptation. This paper explores the possibility of bitrate reduction and proposes an algorithm to calculate the cost of each 8x8 subMacroblocks. Based on the threshold and the cost...
This paper describes the problem of inferring the complex causal relationships among genes from microarray experimental data based on a fuzzy Petri net (FPN). The method derives information on the gene interactions in a highly interpretable form (fuzzy rules) and takes into account dynamical aspects of genes regulation. The approach of the fuzzification of the Petri net is proposed. A token in the...
Modelling and simulation of closed loop controlled class D current source resonant inverter (CSRI) for ferromagnetic load is presented in this paper. The converter can operate effectively even for fluctuating source and it operates in zero-current switching mode. The switching devices are connected through a common ground and need only a single DC power supply for the gate driver circuitry. The aim...
A new iris recognition system based on Wavelet Packet Analysis is described. The most unique phenotypic feature visible in a person's face is the detailed texture of each eye's iris. The visible texture of a person's iris is encoded into a compact sequence of 2-D wavelet packet coefficients, which generate an "iris code". Two different iris codes are compared using exclusively OR comparisons...
One of the important issues in the design of fuzzy classifier is the formation of fuzzy if-then rules and the membership functions. This paper presents a Niched Pareto Genetic Algorithm (NPGA) approach to obtain the optimal rule-set and the membership function. To develop the fuzzy system the rule set and the membership functions are encoded into the chromosome and evolved simultaneously using NPGA...
This paper provides on effective Shuffled Embedded Technique (SET) to eliminate the drawback of substitution technique. Using the genetic algorithm, message bits are embedded into multiple, vague (blurred) and higher LSB layer in order to increase robustness, which is achieved by embedding secret messages in digital audio stream. Additional careful considerations are taken against the premeditated...
Computational Grid is a distributed computing paradigm that provides huge computational power for the large scale distributed application. One of the challenging issues in Grid Scheduling is dynamically choosing the best resource, by exploiting the topology and load information present at the time of scheduling. Here topology represents the delay or elapse time to reach the resource. In the proposed...
Multiprotocol Label Switching (MPLS) is an Internet Engineering Task Force (IETF) specified framework that provides for the efficient designation, routing, forwarding and switching of traffic flows through the network. MPLS is a versatile solution to address the problems faced by present-day networks like speed, scalability, quality-of-service (QoS) management, and traffic engineering. MPLS carries...
This paper presents an ultra-wideband (UWB) bandpass filter for UWB applications and notch filter for the purpose of reducing interference from the WLAN (802.11a) when it coexist with UWB radio system. The bandpass filter consists of a hexagonal shaped multiple mode resonator (MMR) with interdigital coupling at both sides. The notch filter consists of four identical open ended stubs nearby the MMR...
Fractal Analysis is the well developed theory in the Non-linear Analysis of Biomedical Signals such as Electroencephalogram (EEG). EEG signal is essentially multi scale fractal, i.e. Multifractal. Therefore Multifractal measures such as Generalized Fractal Dimensions (GFD), could be a useful tool to compute the degree of disorders, complexity, irregularity and chaotic nature of the Biomedical Signals...
The biconical dipole antenna is frequency independent antenna. A dipole antenna is a narrowband and frequency dependent. In this paper a linear array of five biconical antennas with cone angle 30 is modeled in WIPL-D software and analyzed. Radiation pattern, gain, impedance and Sparameter plots of the array are analyzed and presented for 1-5 GHz frequency range. Mathematical equations for the parameters...

The effect of optimum numbers of inner iterations and numbers of hidden nodes on learning time and recognition rate has been shown. The Principal Component Analysis and Multilayer Feed Forward Neural Network are applied in face recognition...
"Process Automation in Strategic Command Decision Support System" (PASC DSS) is a program being executed by Center for Artificial Intelligence and Robotics (CAIR) to provide Indian Defence with a system built on leading edge technology. PASC DSS helps in collecting, collating, filtering, processing, synthesizing and displaying the information gathered from various sources and provide support...
Neutralizing pH value of sugar cane juice is the important craft in the control process in the clarifying process of sugar cane juice, which is the important factor to influence output and the quality of white sugar. On the one hand, it is an important content to control the neutralized pH value within a required range, which has the vital significance for acquiring high quality purified juice, reducing...
Acoustic communication has been widely used in wireless sensor networks. Vehicle acoustic signals have long been considered as unwanted traffic noise. In this research acoustic signals generated by each vehicle will be used to detect its presence and classify the type. The goal of multiscale PCA (MSPCA) is to reconstruct a simplified multivariate signal, starting from a multivariate signal and using...
This paper presents the use of fuzzy logic control (FLC) of a variable speed induction machine wind generation system. The generation system uses three fuzzy logic controllers (FLC's), first fuzzy logic controller tracks the generator speed with wind velocity to extract maximum power. Second fuzzy logic controller programs the machine flux for light load efficiency improvement. Third fuzzy logic controller...
This paper aims to estimate the error in the control of a robot arm model by analyzing dynamics of the robot arm. The dynamics of robot arm has represented in the form of second order differential equation. A meticulous attempt has been made to estimate the error by comparing the solutions obtained using Single Term Walsh Series (STWS) and Single-Term Haar Wavelet Series (STHWS) method. The exact...
Bombs are detected by different machines and mediums but all works only under the presences of experts. They will analyze the presence and type of bombs. But this way of analyzing takes long time.
