هدف از این تحقیق، ارزیابی و بهبود متریک های موجود جهت تایید صحت نقشه های قدیمی سه بعدی برداری با استفاده از ابر نقطه حاصل از لیزر اسکن جدید شهر اصفهان می باشد . بنابراین ابر نقطه حاصل از لیزر اسکنر با چگالی حدودا سه نقطه در هر متر مربع جهت شناسایی عوارض تغییر کرده در نقشه های قدیمی سه بعدی استفاده شده است. تمرکز ما در این تحقیق بر روی ساختمان به عنوان یکی از اصلی ترین عارضه های شهری می باشد. من...
Optimal Control Pressure for Leakage Minimization in Water Distribution Systems Using Imperialist Competitive Algorithm
One of the key factors affecting leakage in water distribution systems is network pressure management by putting Pressure Reduce Valves (PRV) in the flow path and optimal regulation of these vales in water networks. This study aimed at investigating optimal pressure management problems so as to minimize leakage in water distribution networks. To do so, an approach was proposed for both optimal ...
متن کاملTackling uncertainty in safety risk analysis in process systems: The case of gas pressure reduction stations
Industrial plants are subjected to very dangerous events. Therefore, it is very essential to carry out an efficient risk and safety analysis. In classical applications, risk analysis treats event probabilities as certain data, while there is much penurious knowledge and uncertainty in generic failure data that will lead to biased and inconsistent alternative estimates. Then, in order to achieve...
متن کاملPressure Signatures of Damaged Valves
Selection of shaft geometry is critical to the overall performance of a rotary compressor. Consideration is given to the development of rotary compressor shaft geometries to optimize efficiency and reliability. The cylinder to piston dynamic clearance is of prime importance with respect to leakage losses. An analysis of bearing film thicknesses and shaft deflection was conducted to fully evalua...
متن کاملControlling the Water Pressure in the Pressure Control Networks Using a New Automatic Pressure-Reducing Valve
Increase in urban water networks, network management is one of most important problem in which the parameters of the network pressure and leakage at night in search of networks and connections will be worn. Given that the urban water networks with more than 30 years old have been worn and is part of the network and still have not replaced the night of exhaustion and pressure leakage is due to i...
