In this paper the operation of multiple reservoirs by the utilization of analysis method of the system dynamics is considering and this analysis method is based on the feedback and object oriented events. The goal of this research is presentation of a new method by utilization of system dynamicity technique for simulation of the reservoir. This software is a product of Ventana Company and the e...

A simple method for the synthesis of octahydroquinazolinone derivatives in the presence of BF3.SiO2 and Insecticide activity of these compounds against spodoptera litura was investigated to be comparable to commercial pyrethroid insecticides, Cypermethrin and Cyhalothrin. The structure of the isolated compounds was characterized by 1HNMR and FT-IR spectroscopy.The proposed method had some ad...

this paper deals with optimal operation of a three-product dividing-wall column (dwc). the main idea is to design a control structure, through a systematic procedure for plantwide control, with an objective to achieve desired product purities with the minimum use of energy. exact local method is used to find the best controlled variables as single measurement or combination of measurements base...

In automotive industry fixtures have a direct effect on product manufacturing quality, productivity and cost, as a result fixtures, particularly welding fixture, play a crucial role in the auto industry. The fixture is a special tool for holding a work piece in proper position during manufacturing operation, so in the phase of the fixture design process positioning pins and surfaces are used to...

Computer-aided process planning (CAPP) is an essential component in linking computer-aided design (CAD) and computer-aided manufacturing (CAM). Operation sequencing in CAPP is an essential activity. Each sequence of production operations which is produced in a process plan cannot be the best possible sequence every time in a changing production environment. As the complexity of the product incr...

Beyond Budgeting has been proposed as an influential idea that will reinvigorate management accounting contribution in business operation and performance. It is claimed that the traditional system has lost relevance with the modern business environment and is no longer satisfying the needs of managers. Budgets have been ingrained in the culture of business since their inception in the 1920s and...
