The motivation behind this work is to explore and pursue benefits of Cognitive Informative and Artificial Intelligence. Computer based Image Analysis and Machine Vision are based on Image Processing Algorithms. Choosing the best concept to comprehend a meaning in natural language generation is one of the tough tasks. A vision system while navigating in an environment should be able to recognize what...
The problems of predicting the Protein-Protein Interactions (PPIs) are characterized by probabilistic constraints using the artificial neural network techniques. In the literature, no specific rules are proposed for determining whether two proteins interact, but various approaches have been proposed to collect the information about the interaction between the proteins. The need and importance of PPIs,...
In this paper, a complete simulation model of a single phase grid-connected photovoltaic (PV) system with associated controllers is presented. The simulation model is developed in MATLAB/SIMULINK tool. The main component of the single phase grid-connected PV system are, a PV array, a dc-dc boost converter, a PWM based voltage source inverter and filter. For high efficiency of the PV system used maximum...
A highly efficient differential cross coupled voltage controlled oscillator (VCO) with transformer tuning is presented here for V band (60 GHz) application. Here Tuning is done by on chip octagonal transformer which is used as inductive element in LC tank. This transformer tuning scheme gives three bands of frequency to cover 7 GHz bandwidth of 60 GHz unlicensed band and gives low phase noise as compared...
This paper presents H-bridge converter which is bridgeless boost converter with sinusoidal pulse width modulation to improve the quality of utility mains ac supply. Due to nonlinear loads and common mode voltage harmonics are produced on the supply side which can be reduced using sinusoidal pulse width modulation technique for H-bridge converter. To reduce the common mode noise currents the grounds...
Frequent itemset mining is the first step of association rule mining. Association rule mining in online data mining is one of the most chalanging task due to data stream. A data stream is a huge, infinite, continuous, fast changing and rapid sequence of data elements. Traditional techniques for finding frequent itemset required many passes but stream data require only one scan over the data for finding...
Content-Based Image Retrieval (CBIR), a technique which uses visual contents to search images from large scale image databases according to users interests. In most of image retrieval systems, accurate and partial relevant matching is main issue. Partial duplicate image retrieval is most complicated task as region of interest may undergo occlusion, rotation, scaling and other transformations. Retrieval...
The QRS complex is the most striking waveform within the electrocardiogram (ECG). QRS provides the fundamentals for almost all automated ECG analysis algorithms. We proposed a novel method for classification of ECG beats using shared counters. We first developed a real-time QRS detection technique using two-phase hashing to extract precise QRS points. Then we proposed a classifier for profiling an...
Mobile ad hoc network is a network of wireless node connected using wireless media. Each node operates as a router for all other nodes in the network. Nodes in MANET are mobile and hence change their topology dynamically. From one source to destination node there may be multiple paths. Due to wireless link mobile ad hoc networks are susceptible to many attacks. One popular attack on mobile ad hoc...
This paper proposes an approach for early detection of transient instability of power system for initiating the emergency control in time. The synchrophasor measurements are used for real-time monitoring of the system. The Artificial Neural Network (ANN) is used as classifier for predicting the transient instability status of the system with rotor angles and speeds (frequency) of generator as inputs...
In VLSI, transistor scaling plays an important role in reducing the power dissipation and increasing speed from one technology node to another technology node. But transistors are scaled further in size then it will lead to number of limitations like short channel effect, sub-threshold condition, body effect, aging effects etc. Negative Bias Temperature Instability (NBTI) is increase in threshold...
In this paper a new design of band notch UWB antenna which is Coplanar Waveguide (CPW) fed printed octagonal aperture antenna with back patch is presented. A rejected frequency band of 5–6 GHz is obtained by etching H shaped slot from back patch of conventional UWB antenna [1]. The proposed antenna is successfully simulated, fabricated and measured. Both impedance and radiation characteristics obtained...
This paper presents a method for refining the speed control of Direct Torque Control (DTC) of induction motor drive using Genetic Algorithm (GA) tuned proportional plus integral plus derivative (PID) controller. The DTC is widely used for controlling of torque and flux of induction motor drive (IMD). In addition to, IMD has following drawbacks such as multi-variable, strong coupling, non-linear and...
Design and development work is ongoing to make 2.6 cell photocathode RF Gun with a mode separation of about 15 MHz. This paper provides information on the comparison of simulation results of the 2.6 cells using Superfish and HFSS code. The cavities designed are tuned to achieve π mode frequency of 2856 MHz with a field balance of 1. In the next stage we are making fabrication drawings and will initiate...
The conventional digital computational hardware blocks with different structures are destined to produce precise results. For almost any multimedia application the human eye is the receiver of information. Owing to the fact that human eye is capable of gathering intended information from slightly erroneous output also, this work deals with the design of low power inexact 4:2 compressor using approximation...
In this paper, the problem of spare core position when faults occur at core on Network on Chip (NoC) is proposed. More precisely, a fine grained spare core position is proposed, which goes for enhancing the entire system performance and communication energy consumption, while considering the occurrence of permanent, transient and intermittent faults in the system. This method finds the spare core...
