Improvements to Filter Debris Analysis in Aviation Propulsion Systems

The accurate analysis of metallic wear debris is fundamental to determining the health of aviation propulsion oil-wetted systems. The oil filter is an excellent source of wear debris, however methods for removing and assessing the debris have traditionally involved tedious visual examination of the filter pleats and manual counting of particles. This report describes two enhanced methods for ex...

Preliminary Experimental Analysis of Alcohol-Kerosene Blend for Commercial Aviation

Teh aim of dis work is to provide insight into alcohol-kerosene fuels and their promising use as an alternative in commercial aviation. A detailed chemical and physical experimental analysis is drawn, wif a focus on teh advantage of teh isopropanol-kerosene blend. Despite reported beneficial isopropanol effects on retarding fuel combustion, knocking prevention, and much lower emissions, few...

analysis 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...

Interference Analysis for Dedicated Indoor WCDMA Systems

In a previous paper we showed results for the coverage and capacity for passive and active WCDMA DAS indoor installations using a simplified model with the other-cell interference factor as an input parameter to the simulation [1]. In this paper we calculate the other-cell and own-cell interference for the radio downlink using a network simulator for the outdoor and indoor environment. Abstract...
