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 اول2D plasma sheet ion density and temperature profiles for northward and southward IMF
[1] We previously developed a method for inferring plasma sheet ion temperature and density from ionospheric observations. Using this method and DMSP observations for 1992, we present 2D profiles of the equatorial plasma sheet ion density and temperature for southward and northward IMF for b2i > 64 or Kp < 3. During periods of northward IMF, cold dense ions can be found plentifully along the pl...
متن کاملPolar, Cluster and SuperDARN evidence for high-latitude merging during southward IMF: temporal/spatial evolution
Magnetic merging on the dayside magnetopause often occurs at high latitudes. Polar measured fluxes of accelerated ions and wave Poynting vectors while skimming the subsolar magnetopause. The measurements indicate that their source was located to the north of the spacecraft, well removed from expected component merging sites. This represents the first use of wave Poynting flux as a merging discr...
متن کاملOn the origins and timescales of geoeffective IMF
Southward interplanetary magnetic field (IMF) in the geocentric solar magnetospheric (GSM) reference frame is the key element that controls the level of space weather disturbance in Earth’s magnetosphere, ionosphere, and thermosphere. We discuss the relation of this geoeffective IMF component to the IMF in the geocentric solar ecliptic (GSE) frame, and using the almost continuous interplanetary...
متن کاملGeomagnetic Activity Forecasting: the State of the Art
Short-term (days to weeks) geomagnetic forecasts are valuable for a variety of public and private sector endeavors. However, forecast skill, as measured by the success of predicting geomagnetic indices, is disappointing, especially for disturbed conditions. Possible reasons for this lack of proficiency include an incomplete understanding of the solar origins of interplanetary disturbances, insu...
