Abstract: The combination of wrought aluminum-magnesium-silicon alloy confirming to aluminum AA6061 alloy widely accepted because of light weight fabrication structures, high strength to weight ratio and good corrosion resistance. Friction Stir Welding(FSW) process is an emerging solid state joining process in which the material that is being welded does not melt and recast when compared to fusion welding process that are routinely used for joining structural aluminum alloys. In this FSW process a non consumable tool is used to generate frictional heat in the abutting surfaces. Experiments for surface roughness, Rockwell hardness and tensile tests are carried out and reported in this paper. The base material used for friction stir welding is aluminum AA 6061 alloy..

Abstract: The main gearbox is an important driving force for a pump. It needs to carry out regular monitoring. In this paper, it measures the vibration acceleration signal of a pumping unit's main gearbox, names them 1# and 2#. After comparing the time course curve and spectral of the two main gearbox, it has found the 2# gearbox's maximum amplitude is about 2.5 times than the 1#, and the frequency which corresponds to the spectral value is close to the meshing frequency. The narrowband signals are filtered by Hilbert transform to obtain the envelope of the narrow band signal.

Abstract: The numerical studies are performed to examine the mass transfer flow with thermal diffusion and diffusion thermo effect past an infinite, inclined vertical plate in a porous medium in the presence of chemical reaction. First of all, the governing equations are transformed to a system of dimensionless coupled partial equations. Explicit finite difference method has been used to solve these dimensionless equations for momentum, concentration and energy equations. During the course of discussion, it is found that various parameters related to the problem influence the calculated result. Finally, the profiles of velocity, concentration and temperature
are analyzed and illustrated with graphs.

Abstract: A turbine jet engine has four main parts, They are compressor, combustion chamber, turbine and exhaust nozzle. Turbine jet engine operates at an open cycle called a jet propulsion cycle. A small-scale turbine jet engine comprises of the same element as the gas-turbine engine but in a small scale. Turbine jet engines are constructed mainly for air transportation while the turbine jet engines are developed for a wider purpose, ranging for research activity to hobbyist enthusiastic. Hence, this paper encompasses the design, fabrication, and testing a turbine jet engine. The engine is derived from an automobile turbocharger, which provided the turbine and compressor component.

Abstract: Mini bikes are normally preferred by for their light weight. Hence attention needs to be focused on weight while configuring each and every key element like brake, gear box,engine, clutchs etc. Design optimization of brake for one such mini brake has been taken up in this work. To start with, mathematical model of the brake has been established so as to bring out the relation between key parameters of the design and the same has been used in the later stage so as to formulate the optimization strategy. Configuring the brake by choosing restraining value of width of brake lining in place of choosing restraining value of size of brake drum yielded to reduction of volume and hence weight.

Abstract: The Straddle Carrier (SC) is a very popular piece of equipment. These carriers can undertake a variety of handling operations such as loading, unloading, stacking and transport of containers between the landside and waterside. Its popularity is due to its space efficiency and flexibility. Traffic incidents are a serious problem at marine terminals, where heavy equipment is used to load and unload ships and move freight from place to place in the terminal. The work is fast-paced, conducted at any time of the day or year, and often performed in inclement weather. Vehicular traffic endangers any worker walking in a marine terminal.

Abstract: The aim of this study was the determination of the chemical composition of vegetable water derived from olive oil elaboration and evaluation of the main features modified through chemical-physical interactions (connection, inter effects) physical, chemical and biological between soil and effluent. The experiment was carried out in a field located near factory of olive oil production in Lunder Tirane during the years 2012-2014. The indicators that are analyzed are: pH, CE, L.O, Na, K, N, P. Based on the results, we found that the analyzed parameters have resulted in limits: pH 7.86-8.51, CE 22.4-290, L.O 9269.8-40216.09, rich in potassium (K) 4575.1-6627.5. High content of potassium and organic matter has a positive effect on the improvement of soil characteristics, because most of the olives plantations are planted in poor areas with organic matter and on the other hand olives needs land rich in potassium. Modification of characteristics of effluent on land during the 10, 100, 190 and 280 days could give us more accurate data on fertilisations of soils with a lower cost. Keywords: Olive mill wastewater, agricultural land, soil properties, environmental pollution.

Abstract: The present paper demonstrates an analytical model that simulates a single story brick masonry in-filled frame strengthened by carbon–fiber reinforcement polymer (CFRP) to resist lateral loads. This paper is a part of a comprehensive research related to characterize the behavior of CFRP in retrofitting In-filled Frames. The pervious phase was an experimental program carried out on half scale specimens to study the effectiveness of different strengthening techniques for in-filled frame. The experimental results showed that the used strengthening methods were effective, with high increase in strength and ductility. In the current phase, an analytical analysis was presented and solved. Based on this model, two design equations to determine the required amount of FRP needed to resist lateral loads were proposed. The first formula represents the accurate solution while the second one is a simplified empirical design equation. They showed good agreement with the experimental result of the first research phase.
