Performance analysis of antennas for hand-held transceivers using FDTD

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...

FDTD Analysis of Top-Hat Monopole Antennas Loaded with Radially Layered Dielectric

Top-hat monopole antennas loaded with radially layered dielectric are analyzed using the finite-difference time-domain (FDTD) method. Unlike the mode-matching method (MMM) (which was previously used for analyzing these antennas) the FDTD method enables us to study such structures accurately and easily. Using this method, results can be obtained in a wide frequency band by performing only one ti...

Simulated Performance of Conical Antennas Using Matlab-Based Finite-Difference Time Domain (FDTD) Code

The need of ultrawideband (UWB) antennas with omni-directional coverage is increasing for both military and commercial applications (Wiesbeck et. al., 2009; Minin, 2010). The UWB radio technology promises high resolution radar applications, sensor networks with a large number of sensors for industrial or home surveillance as well as high data-rate communication over short range for personal are...

Using Mobile Hand-Held Computers in Disasters

This paper discusses the design and prototypical implementation of a mobile user-interface to assist paramedics in disaster operations based on the mSTaRT triage algorithm. Due to the increasing use of algorithms in the disaster management the introduction of mobile hand-held computers stands to reason. The triage algorithm has been implemented on hand-held computers and tested in a disaster co...
