global results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Vulnerability and Environmental Risk Assessment
Over the past half century, environmental risk assessment (ERA) has become increasingly important in political decisions. It forms an important basis within the World Trade Organization’s Sanitary and Phytosanitary Agreement (SPS) and is an important touch point within the Convention on Biological Diversity. The scope of ERA is expanding rapidly both in the issues that it covers and in its role...
متن کاملEnvironmental Risk Assessment
This paper presents a current overview of the basic elements of environmental risk assessment within the basic four-step process of hazard identification, exposure assessment, toxicity assessment, and risk characterization. These general steps have been applied to assess both human and ecological risks from environmental exposures. Approaches used to identify hazards and exposures are being ref...
متن کاملThree Environmental Probabilistic Risk Problems
Risk analysis may be defined as the problem of estimating the probabilities of rare events and the magnitudes of associated damages. The topic unifies the environmental sciences. This paper considers risk analyses for earthquakes, wildfires and floods. The computation of insurance premiums is used to motivate and unite the work.
متن کاملEnvironmental risk assessment of a dam during construction phase
The present study was conducted to assess the possible risks induced by construction of Gavi Dam in Ilam Province; western part of Iran, using MIKE-11 model and technique for order of preference by similarity to ideal solution. For this purpose, vulnerable zone of the dam site against the flooding risk of Gavi River was calculated for different return periods. The flooding zones were stimulated...
