M - band wavelet transform...
Multilevel inverters have gained interest in recent years in high-power medium-voltage industry. This paper considered the most popular structure among the transformer-less voltage source multilevel inverters, the diode-clamped inverter based on the neutral point converter. This paper use conventional switching sequence and optimum switching sequence of SVPWM technique. Simulation results presents...
This paper presents the comparison between improved asymmetric space vector modulation (ASVM) and sinusoidal pulse width modulation (SPWM) for voltage source converters (VSCs) when the switching frequency is as low as 9 times of line frequency. By adding two pulses in each line cycle when the fundamental voltage crosses zero, the total harmonic distortion (THD) of output current can be reduced significantly...
The objective of the paper is, a new normalized block LMS algorithm is developed for adaptive decision feedback equalizer (ADFE), which is suitable for high data rate wireless and mobile communication systems. Physical channels used in transmission of digital signals can be rarely represented by a nondistorting channel model with additive noise as the only impairment. In practice, the vast majority...
Image fusion refers to the process of combining the relevant information from two or more images into a single highly informative image. The resulting fused image contains more information than the input images. In this paper, an algorithm for fusing two different modality medical images based on the Multi-Wavelet Transform (MWT) and Curvelet transform using different fusion techniques was implemented...
High-performance variable speed drives require a better transient performance compared with the steady-state operation. Nowadays, vector control and direct torque control (DTC) are popular methods for high performance drives. This paper presents a new vector control method for voltage-source inverter fed induction motors using look-up tables. The proposed method uses a predetermined look-up table...
A Biometric system is essentially a pattern recognition system that makes use of biometric traits to recognize individuals. Authentication systems built on only one biometric modality may not fulfill the requirements of demanding applications in terms of properties such as performance, acceptability and distinctiveness. Most of the unimodal biometrics systems have problems such as noise in collected...
In this paper, a detailed study of the performance of rotor flux and reactive power based MRAS rotor resistance estimators for Vector Controlled Induction Motor drive is presented. The rotor resistance changes significantly during operation of the drive due to temperature rise and saturation. This variation has a major influence on the performance of the field oriented control of induction motor drive...
Solar integrated current-fed quasi-Z-source inverter (qZSI) have been proposed to overcome the limitations of current-source inverter (CSI) and current-fed Z (impedance) source inverter (ZSI). The problems with CSI are unidirectional power flow and can perform only voltage boost operation. On the other hand ZSI is bidirectional with an additional diode and have voltage buck-boost capability. The techniques...
Automated and early diagnosis of Diabetic Retinopathy is a crucial need. ‘Diabetic Retinopathy’ (DR) is the major cause of blindness among people. It is a progressive disease classified according to the presence of various clinical abnormalities. DR patients perceive no symptoms until the disease is at late stage. So early detection and proper treatment has to be ensured. To serve this purpose, various...
During the last few years, emission control has become a problem of global concern due to the constantly increasing pollution of earth's atmosphere. The generator company objectives are to maximize their profit. The traditional generation scheduling problem aims at minimizing the cost of operation subject to fulfillment of demand. Under new structure, generation companies (GENCOs) schedule their generators...
Static Synchronous Compensator (STATCOM) is one of the typical FACTS device which is used to improve the voltage profile and transient stability in power system by damping the low frequency oscillation in it.

This paper presents a multifocus image fusion based on sparse representation theory. In the method, first the source images are decomposed by an overcomplete dictionary that contains prototype signal atoms into their corresponding sparse coefficient. Secondly, the corresponding coefficients of the sources images are combined with the choose-max fusion rule. Finally, the fused image is reconstructed...
Ranking is an important property that needs to be fully supported by current relational query engines. Given a set of objects for all functions F over P, an interesting problem is to compute the top ranked objects for all functions. Ranking queries (or top-k queries) are dominant in many emerging applications, e.g., similarity queries in multimedia databases, searching Web databases, and data mining...
A high performance electrical drive requires suitable control method, even when the load and parameters of the motor are varying during the motion. This paper proposes Adaptive Neural Fuzzy Inference Systems (ANFIS) controller for minimum switching loss PWM algorithm based vector controlled induction motor drives. In the conventional space vector PWM (CSVPWM) algorithm, the zero voltage applying time...
In image restoration applications, Sparse representation which is a statistical image modelling technique has been widely used. The image restoration quality depends on sparse representation of the original image. Considering that the contents can vary across different images or different patches in a single image, so we have to study a number of sets of bases from a example image patches, one set...
The design for low power has become one of the greatest challenges in high-performance very large scale integration (VLSI) design. It has been found that the power consumed during test mode operation is often much higher than during normal mode operation. This is because most of the consumed power results from the switching activity in the nodes of the circuit under test (CUT), BIST technique uses...

A mobile ad-hoc network (MANET) is a collection of mobile nodes which communicate over radio. These kind of networks are very flexible, thus they do not require any existing infrastructure or central administration. Therefore, mobile ad-hoc networks are suitable for temporary communication links. As the nodes are mobile, it is very difficult to find the path between two end points. This paper presents...
