Multidisciplinary Thermal Analysis of Hot Aerospace Structures
Hypersonic flight introduces extreme heat loads into the leading edges of a vehicle. Determining these loads is challenging. It requires accounting for the aerothermodynamic features of both the flow and thermal state of the surface. These features can be influenced by pressure and viscous effects, real-gas and low density effects, inonization, radiative heating, surface-radiation cooling, and ...
متن کاملanalysis of ruin probability for insurance companies using markov chain
در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولModitication Factor for Sizing Equation of Electrical Machines-Single and Three Phase Induction Motors(RESEARCH NOTE)
Comparison between the results from the design procedure based upon the value of D2L (volume of iron) and IEC standard used by manufacturers indicates that the basic design equation of electrical machines must be modified by a proper modification factor. This modification factor is evaluated for single- and three-phase induction motors and its variation with motor rating and poles number is obt...
متن کاملControl of Electrical Machines for Drives
Electric drive systems are one of the most important components of our life; billions of them are used in industry, traffic applications and private environment. In the recent past an accelerated development of controlled drive systems could be experienced. The scientific and technical background of today’s most important drive systems, the converter controlled DC-drives and the vector controll...
متن کاملAn Approximation Algorithm for the FaultTolerant
We consider a fault tolerant version of the metric facility location problem in which every city, j, is required to be connected to rj facilities. We give the rst non-trivial approximation algorithm for this problem, having an approximation guarantee of 3 Hk, where k is the maximum requirement and Hk is the k-th harmonic number. Our algorithm is along the lines of 2] for the generalized Steiner...
