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 اولHigh-precision spectroscopy of antiprotonic helium atomcules
The study of pHe atomcules carried out by the PS205 collaboration at CERN-LEAR revealed many facets of this unusual 3-body system. Its structure was rst examined using a laser spectroscopy technique where it could be shown that the antiprotons occupy highly excited metastable states with principal quantum number n = q (m=M) and orbital angular momentum quantum number l = n 1 as predicted by the...
متن کاملHigh Precision Rovibrational Spectroscopy of Oh+
The molecular ion OH has long been known to be an important component of the interstellar medium. Its relative abundance can be used to indirectly measure cosmic ray ionization rates of hydrogen, and it is the first intermediate in the interstellar formation of water. To date, only a limited number of pure rotational transitions have been observed in the laboratory making it necessary to indire...
متن کاملHigh-precision spectroscopy with counterpropagating femtosecond pulses.
An experimental realization of high-precision direct frequency comb spectroscopy using counterpropagating femtosecond pulses on two-photon atomic transitions is presented. The Doppler broadened background signal, hampering precision spectroscopy with ultrashort pulses, is effectively eliminated with a simple pulse shaping method. As a result, all four 5S-7S two-photon transitions in a rubidium ...
متن کاملHigh-precision and high-accuracy rovibrational spectroscopy of molecular ions.
We present a versatile new instrument capable of measuring rovibrational transition frequencies of molecular ions with sub-MHz accuracy and precision. A liquid-nitrogen cooled positive column discharge cell, which can produce large column densities of a wide variety of molecular ions, is probed with sub-Doppler spectroscopy enabled by a high-power optical parametric oscillator locked to a moder...
