Effective Depth of Soil Column for Site Response Analysis of Deep Soil Sites

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...

Sensitivity of a model projection of near-surface permafrost degradation to soil column depth and representation of soil organic matter

[1] The sensitivity of a global land-surface model projection of near-surface permafrost degradation is assessed with respect to explicit accounting of the thermal and hydrologic properties of soil organic matter and to a deepening of the soil column from 3.5 to 50 or more m. Together these modifications result in substantial improvements in the simulation of near-surface soil temperature in th...

Predicting the amount of sequestrated carbon in rangeland soil under the effect of soil sampling depth and height using the response surface methodology (RSM)

Background and objectives: Organic carbon is one of the important parameters to determine soil fertility, and production ability and is a mind index for showing soil quality, especially in dry and semi-dry lands. The rangelands are composed of about 50 % of the world's lands and have more than 33 % of carbon reservoirs on earth. Considering the ranges as the most important terrestrial ecosystem...

Response of Hanford Site Soil Arthrobacter Isolates to Uranium Contamination

Uranium is one of the most prevalent radiological groundwater and soil contaminants at Hanford, the U.S. Department of Energy (DOE) site, Washington State, USA. Bioremediation strategies, such as injections of a soluble sodium tripolyphosphate amendment into the contaminated groundwater in order to sequester uranium through the formation of insoluble uranyl phosphate minerals, may have resulted...
