Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 2 (February 2017)

Abstract

India is a country with huge population and variety of geographical locations. It has many places where high altitude mountains are present and have potential to generate the electricity through Hydro power plants. For high head power projects Pelton turbine is the first choice for the alternators. As he Efficiency is better in the above turbine as the research and the previous study has shown. The material by which the turbine is constructed matters a lot in achieving speed as well as efficiency of the entire system.......

Abstract

This paper is concern with theoretical design of the 100 kg solid rocket motor with predefined values of the burning rate is 100 mm/ sec, specific impulse is 240 sec and chamber pressure is 1000 psi. confined with selection of the material and basic concept of the rocket motor and its aspect during static test. Rocket motor is a highly complex aerospace component that consists of a metal casting, ablative liner and propellant grain. Also to determine the design pressure and burst pressure of a solid rocket motor casing .Preliminary design provided key propulsion outputs that would later be refined and assessed in the final design.

Transient Thermal Analysis of AlSiCp Composite Disc Brake

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 2 (February 2017)

Abstract

Disc brakes are devices which will slow down or stop the heading vehicle. During the process of braking the brakes get heated up. Repeated braking will cause the excessive heating of the disc and braking action becomes less effective when the disc is over heated. So it is very much necessary that the heat generated is dissipated faster or the disc material gets less heated. In this paper we have considered a metal Matrix Composite AlSiCp which will satisfy these criteria. An analysis of composite and CI disc brakes over a repeated braking is done and the results are analyzed.......

Abstract

The X-ray diffractogram of raw ginger (Zingiber officinale), turmeric (Curcuma longa) and eri (Samia cynthia ricini) fibers are taken at different temperatures ( 313, 353, 393, 433 and 473 K) in an X-ray powder diffractometer (Phillips X'Pert Pro) with high temperature attachment (Anton Paar, HTK-16). It is found that the percentage of degree of crystalinity first increases from its value at 313K to the value at 353K, and then decreases at higher temperature for all the experimented raw fibers. The degree of crystallinity finds to be maximum at temperature 353K. The degree of crystallinity of chemically treated ginger fibers also finds to decrease with the rise of temperature with maximum at 353K. The degree of crystallinity of ginger fiber finds to increase due to degumming at a certain temperature.

Keywords: Zingiber officinale, Curcuma longa, Samia cynthia ricini, Degree of crystallinity, x-ray diffractogram.

Study of the Class and Structural Changes Caused By Incorporating the Target Class Guided Feature Subsetting in High Dimensional Data

Paper Indexed : : 03.3005/xxxxxxx
International Journal of Computational Engineering Resaerch, Volume 07 ~ Issue 2 (February 2017)

Abstract

High dimensional data when processed by using various machine learning and pattern recognition techniques, it undergoes several changes. Dimensionality reduction is one such successfully used pre-processing technique to analyze and represent the high dimensional data that causes several structural changes to occur in the data through the process. The high-dimensional data when used to extract just the target class from among several classes that are spatially scattered then the philosophy of the dimensionality reduction is to find an optimal subset of features either from the original space or from the transformed space using the control set of the target class and then project the input space onto this optimal feature subspace...........

Keywords: Class of Interest-CoI, target class, feature subsetting, Agglomerative Clustering, Minimum Spanning Tree, K-NN, density, structural property-false acceptance Index, structural property index.

Abstract

Refractive index(n), Electronic Polarizability (αp), Optical Energy Gap(Eg) and optical electronegativity(Δχ*), of I-III-VI2 and II-IV-V2 groups of ternary semiconductors have been calculated using Plasmon energy data on the basis best fit data, new relations have been proposed for the calculation of refractive index , electronic polarizability, optical energy gap and optical electronegativity. The calculated values of n, αp, Eg and (Δχ*) from the new relations have been compared with the values reported by different researcher. An excellent agreement with calculated values and experimental values has been obtained.
