Developing a Hybrid Technology Evaluation Model for Minimization of the Cost of the Dynamic Effects of Changes and Resource Consumption on Ecosystem Sustainability
, Ph.D. Dissertation Sharif University of Technology ; Saboohi, Yadollah (Supervisor)
Abstract
Rapid population growth and increasing and rapid consumption of natural resources in the ecosystem leads to the destruction of resources and thus increases the entropy in the earth, and this increase in entropy in the ecosystem changes the environment and has adverse effects on it. As all components in nature interact with each other by action and reaction, therefore, any change in the environment must be adjusted by other sectors and approached a reversible process to enable sustainable ecosystem changes. On the other hand, there is evidence that the world's physical capacity is inadequate to meet the requirements of sustainable development. The reason for this fact is that the ecological...

Abstract
Conventional models of cardiovascular system (CV) frequently lack required detail. Once utilized to study the heart function, these models focus primarily on the overall relationship between pressure, flow and volume. This study proposes a localized and regional model of the CV system. It utilizes non-invasive blood flow and pressure seed data and temporal cardiac muscle regional activation to predict the operation of the heart. Proposed localized analysis considers specific regions of the heart, namely base, mid and apex sections of the left ventricle. This modular system is based on a hydraulic electric analogy model, estimating desired parameters, namely resistance (R), compliance (C),...
