Reduction of VR Using Pi and FLC in a Buck-Boost Converter by Combining SR Buck – KY Boost Converter

In this paper, an analyze and describe step by step process of designing, feedback control and MATLAB simulation of a voltage bucking-boosting converter by combining KY and Synchronous Buck converter for power battery applications. Unlike the traditional buck-boost converter [1, 2, 10, 11], this converter has only the positive output voltage, different from the negative output voltage of the traditional inverting buck-boost converter. This converter operates only in continuous conduction mode. The output current is the non-pulsating waveform thereby not only the current stress on the output capacitor is reduced but also reducing the output voltage ripples. By Combining the KY converter with the synchronous buck converter, a positive buck-boost converter is obtained and uses the same power switches with no right-half-plane zero. So that the circuit is made to be compact and the corresponding cost to below.

A Hybrid Approach to Detect and Recognise Faces in Complex Background

Face recognition from image or video is a popular topic in biometrics research. In this research work a new hybrid approach to detect and recognize faces is proposed and implemented. The proposed algorithm uses Viola Jones method to detect face area from a complex background and then uses the same image to create a database of images. In the recognition part, it again detects the face area and computes the Euclidean Distance of the current face with that of the face images in the training database. The minimum Euclidean distance parameter is used to recognize the correct face, if it is available in the database. The algorithm shows good results in terms of recognition rate as compared to some previous research work in similar field.

Res Judicata

My research is all about the topic Res Judicata which comes under section 11 of civil procedure code 1908. The main purpose of my study is to give a brief summary on the topics for easy reference. I mainly concentrated on the impact, doctine, scope nature, application and non applications of res judicata.

Persuade of Development Parameters on Diffusion Coupled Joints of Dissimilar Materials – An Analysis

Diffusion bonding method is an alternate technique to join like and unlike materials with minimum dimensional tolerance. It is the solid-state process in which two metallic surfaces are made to contact at the elevated temperature and pressure. Diffusion bonding process provides high eminence joints without post-weld machining. The main process parameters of diffusion bonding embrace temperature, pressure and holding time. It is significant that the metallic surfaces should be spotless and free from oxides and nonmetallic films. In diffusion bonding technique microstructural changes were formed in the base metal which determines the mechanical properties of the bond at the interface. Diffusion bonding method can be used to weld the dissimilar materials with different chemical and mechanical properties. The present work reviews the influence of process parameters on diffusion bonded joints of dissimilar materials in the midst of and with no interlayer. Examination on the microhardness, lap shear and microstructure were made for various dissimilar diffusion bonded joints and finally some general conclusions are summarized.
