 Abstract

In this project, Crops residues (CRs) are roughages that become available as livestock feeds after crops have been harvested. They are distinct from agricultural by-products (such as bran, oil cakes etc).Which are generated when crops are processed. Generally any plant materials that remain after food crops have been harvested are classified as a crop residue. Apart from being a source of animal feed, residues are used as building, roofing and fencing materials, as fuel or surface mulch in crop land. Farmers use crop residues mainly in two ways, e.g.: for fuel as firewood and minor constructions, especially maize and sorghum stovers; for roofing local houses, in the case of wheat, oath or barley straws; as building material for walls of local houses, especially teff straw. But the major use is for livestock feed particularly for draught oxen during dry season.

 Abstract

The textile industry is very concerned with quality, it is necessary to master good quality fabric rolls from the looms. The main objective of this work is to develop a system for the detection and classification of defects in a simple and efficient way using techniques of image processing. The most frequently detected defects are missing weft or warp threads, oil stains and holes. The system works according to four steps. It begin by capturing the image, then eliminate parasite information and increase the sharpness of the image by image analysis. After that, determine three parameters with characterize the mentioned defects (the rate of straight lines, the rate of dark areas and the rate of voids). Finally apply a neural network to recognize the category of defect present on the fabric.

 Abstract

The Geneva drive is a sort of rigging structure that plays out a sporadic rotational improvement. The moving drive wheel includes a stick that comes toward contact with a space of the chose wheel which moves it by one stage. By varying each slot length in the geneva wheel we control the timing at each stage of the conveyor movement by neglecting the usage of sensors.

 Abstract

This paper deals with improving the pump efficiency by modifying the impeller design parameters of existing designl. The most important design parameters are diameter, the inlet and exit angle of impeller, and width of impeller. In this paper the width of the impeller is changed by theoretical calculations for selecting the optimal discharge. 3D Modelling of impeller is done in the solid works software. The outlet characteristics like velocity, volume flow rate, pressures are determined by using the ansys CFX software. The materials considered are manganese bronze, cast steel, Nickel Aluminium.

 Abstract

A method of controlling a gear change of an automobile, said automobile comprising an internal combustion engine; an automatic transmission connected to an output rotation shaft of said engine so as to transmit the rotational output of said engine to drive wheels of said automobile through any selected one of a plurality of gear ratios; a load device selectively connectable to said output rotation shaft of said engine via selectively-connecting means; and means for generating a gear change control signal for selecting one of said gear ratios of said automatic transmission in accordance with one of operational conditions of said automobile and said engine said method comprising the steps of controlling said selectively-connecting means when said gear change signal-generating means generates the control signal for shifting up the gear.There are disclosed an automatic gear change control apparatus for an automobile and a method of controlling such apparatus. A rotational output of an internal combustion engine is connected to drive wheels of the automobile and a load device. When a gear shifting-up of an automatic transmission is to be effected, the load applied by the load device is increased, or the load is connected to an output rotation shaft of the engine via a selectively-connecting device, thereby reducing the rotational speed of the output rotation shaft of the engine to a required level. In our project, two electromagnetic coils are coupled to the gear rod of the two ends. The two buttons are used to activate the electro-magnetic coil so that the gear will be shifted.

 Abstract

: Aircraft wing structures are obligatory to be lightweight in today's designs. However, this lowers the overall stiffness of the wing structure and causes low frequency vibration problems. Active vibration control using piezoelectric patches is an auspicious technology to solve vibration problems of aerospace structures. Many studies were done on aircraft wing geometries, however studies on beam geometry which is used comprehensively as engineering structure, is relatively erratic. The main characteristics of this work were amplification of a finite element model for a plate stiffened by wing surface. Finite element model of the aircraft wing is generated. This study is a postponement of the wing reading with the toting of determining the harmonic analysis to optimal mode shapes of the wing structure. First eight mode shapes used to fine the maximum structure deformation with various frequencies by applying the piezoelectric patches in various locations. From the harmonic analysis we can identifies the exact location of placing the piezoelectric material in the wing structure.

: This paper boarder around the nose landing gear static structural analysis and calculating the fatigue life estimation by various loading condition. The nose landing gear is one of the most primary and important structural component of any aircraft. Landing gear is a crucial part and has been found with increasing failure due to fatigue loading conditions. The nose wheel landing gear is made up of structural steel material and has a good structural composition and physical properties. Therefore, this paper deals with the static structural and fatigue life analysis of nose wheel landing gear. Here the design is made using CATIA V5 software and the fatigue life analysis is carried using ANSYS 16.1 software. Finally, an effort has been made in this paper to investigate the induced stresses and calculated the fatigue lifetime of the nose wheel landing gear.
