The purpose of this research was to study the recognition, application and quantification of the risks associated in managing projects. In this research, the management of risks in an oil and gas project is studied and implemented within a case company in Oman. In this study, at first, the qualitative data related to risks in the project were identified through field visits and extensive interv...

In this paper we address a problem of semi-automated integration of distributed applications. We focus on integration of numerical simulation engineering components. We propose an integration approach that is based on annotation of software interfaces with formal logical specifications. Logical inference procedure is used to choose appropriate enterprise software component depending on client r...

this paper was aimed to report the 3d finite element analysis simulation of laser welding process of ti6al4v 1.7 mm sheets in butt joint in order to predict the temperature distribution, hardness, and weld geometry. the butt-joint welds were made using co2 laser with the maximum power of 2.2 kw in the continuous wave mode. a part of the experimental work was carried out to verify the weld geome...

In this study, the effects of heat treatment of aluminum alloy on the tube bending process were investigated in the rotary draw bending process. As two experimental and numerical simulation methods were used to determine the wall-thinning, ovality, and spring back for extruded, annealed, and aged AA6063 aluminum alloy tubes in different bending angles and bend radii. Numerical simulations were ...

The numerical simulation research of the Underwater Unmanned Vehicle (UUV) shell shape is carried out by applying the modern fluid dynamics numerical simulation technology. In the numerical simulation process, while focusing on the characteristics of the UUV shape, this treatise work properly with its computational model, computational domain, computational grid and boundary conditions. Based o...

proper management of saline soils needs adequate information about the amount and salt distribution in the root zone. irrigation is one of the factors that control the distribution of salt. this study investigated soil leaching simulation by using hydrus2d software based on the evaporation of soil surface of a land without plant located at shahid chamran university, ahwaz, iran. samples were ta...
