Abstract: In recent years, aluminium alloy based metal matrix composites (MMC) are gaining importance in several aerospace and automobile applications. Aluminium has been used as matrix material owing to its excellent mechanical properties coupled with good formability. Addition of Si-C as reinforcement in aluminium system improves mechanical properties of the composite. In this paper, AlSi-C composite was prepared by powder metallurgy route. Powder metallurgy homogeneously distributes the reinforcement in the matrix with no interfacial chemical reaction and high localized residual porosity. Si-C particles containing different weight fractions (10 and 15 wt. %) and mesh size (300 and 400) is used as reinforcement. Though AlSi-C possess superior mechanical properties, the high abrasiveness of the Si-C particles hinders its machining process and thus by limiting its effective use in wide areas. Rapid tool wear with poor performance even with advanced expensive tools categories, it is a difficult-to-.............

Abstract: Box girder is widely used in bridge engineering because of its economy, aesthetic appearance. Now a day it is easy to get safe design due to recent advances in design field but safety with economy is the basic need of present generation, hence it is necessary to go for optimum design. In large span bridges pre stressed concrete is adopted. And thus in present study PSC box girder of span 40m is used for the study. And the loadings are taken as per Indian Road Congress loadings (IRC:6-2014) pre-stressed concrete code (IS:1343-2012) and IRC: 18-2000 specifications. The box girder is designed by limit state method. A computer programme is written in MATLAB-CSI API software for optimization process using genetic algorithm method, and analysis results are retrieved from CSI bridge software to carry out optimization process.

Abstract: The cooling system of internal combustion engine plays a major role in a vehicle performance. In the present work, a proposed electronic controller for the cooling system is introduced and modelled mathematically to control the engine coolant temperature using a controllable electric water pump and radiator fan. Proportional Integral Derivative (PID) and Linear Quadratic Regulation (LQR) control techniques are considered to design the cooling system controller both the coolant flow rate and radiator fan speed are used to control the engine coolant temperature. The Worldwide Harmonized Light Vehicles Test Cycle (WLTC) is used to test the proposed controller based on mathematical simulation using MATLAB/SIMULINK software. The generated numerical results are presented inthetime domain and compared withtheconventional cooling system. The results showed that the proposed controller enhanced the engine coolant temperature either during warm-up or steady-state operation over that oftheconventional cooling system..

Abstract: This study carries out the comparative study of Seismic Performance of residential buildings after partial dismantling for road widening works in Kathmandu city. Two types of buildings were taken for the study i.e. 4 storey building and 6 storey building. The Buildings were assessed for bare frames. The detail level of the seismic evaluation was carried out by preparing 3-D modeling of the buildings in SAP2000 software by nonlinear static pushover analysis. The capacity of the buildings has been found significantly decreased after the partial dismantling of the building due to the road widening works. The behavior of buildings has been found like a strong beam and weak column mechanism.
