Modeling and simulation of cooling systems using PHOTOVOLTAIC SOURCE
Currently, sizing and evaluating photovoltaic installations are based on average consumption profiles rather than scientific criteria or load models. This practice leads to installations fulfilling their tasks, but far from energy and economic optimization conditions that could make the photovoltaic option competitive, reliable, and attractive for more and more applications. Besides, a static knowledge of a photovoltaic system, as obtained during a purely energetic dimensioning, does not allow a reliable approach to the analysis of the system, nor the guarantee of the desired performances. Our work proposes to fill this gap by developing new tools for the simulation, sizing and control of photovoltaic systems. This study is based on three important points: - the development of a dynamic model for each photovoltaic application (pumping, electrification, refrigeration), - the improvement of the DC/DC and DC/AC conversion devices and this by the generation of new control laws associated with the MPPT and PWM modes- The integration of these techniques and these models in software for the management and control of the photovoltaic plant.
Algorithms and Computational Methods
CORDIC, also known as the digit-by-digit method and Volder's algorithm. This is a special-purpose digital computer for real-time airborne computation. In this, a unique computing technique is employed which is especially suitable for solving the trigonometric relationships involved in plane coordinate rotation and conversion from rectangular to polar coordinates. With ongoing technology and limitations on power, operating frequency and energy consumption, if we are generating any trigonometry functions by using of multiplier, adder, divider those architectures consumes more hardware and computational time in- creases, for reduction of this problem CORDIC algorithm is converted into hardware form which is known as CORDIC processor. This processor reduces the problem of division and multiplication. In CORDIC processor we can compute the functions by using of shifter, adder and substractor. In present era CORDIC algorithm is used in many applications like Multimedia, Digital Signal Processing applications like Smooth Filters, DCT, and FFT etc. First CORDIC algorithm is converted into hardware so it was facing some problems like scale factor, time consuming etc.

All the examples can be freely downloaded and most will run on the Elements demonstration version. Once Elements is installed, you can start simulating your converter!Included in this book: ▪ A few pages of theory...▪ Buck Converter in Voltage-Mode Control▪ Buck Converter in Current-Mode Control▪ Forward Converter in Voltage-Mode Control▪ LLC Converters in Various Control Schemes▪ And many more examples with PFC and UC384x circuitsWith this book, you will no longer arbitrarily pick a crossover frequency or phase margin. You will learn how to boost the phase with a compensator using an operational amplifier, a TL431 or an OTA, but also understand how an optocoupler degrades phase margin. I detail options to extend its bandwidth along with many more tricks for making the reader an expert in loop compensation.This book is an ideal companion for graduate and seasoned engineers but also for field application engineers (FAEs) willing to understand the topic and rescue their customers in loop distress.

Algorithms for Efficient Segmentation of Non-ideal Iris Images
Among the biometric technologies available, the iris biometric technology is the most accurate modality, because iris complex random patterns are unique and stable, they do not change throughout a person's lifetime. The Iris recognition is based on the fact that the human iris contains unique features and even genetically identical individuals have entirely independent iris textures. Iris segmentation is an essential step because the actual discriminating information will be present within the iris patterns. Therefore, it is plausible that the initial step in implementing an iris recognition system is separating the iris from irrelevant parts of an eye image, which are of no importance. A pre- segmentation using Otsu's multilevel thresholding and variants of fuzzy c-means (FCM) based on IPSO (improved PSO) and IDSA (improved differential search algorithm) has not been investigated in the literature. The recognition accuracy is affected by noise artefacts that are included during the capturing of iris images. This encourages to effective implementation and accurate pre-segmentation in the recognition framework.
