چکیده
Abstract This paper presents a model concerning interaction of hemodynamics and gas exchange, which involves two physiological systems respiratory and circulatory systems. It consists of five components: a model of gas transport, exchange and storage in the human, a multi-element nonlinear mathematical model of human circulatory system, an alveolar ventilation controller, a cardiac output controller, and a controller of frequency of breathing. Model simulations provided results of both dynamic and steady-state responses under low oxygen (Hypoxia), which can reflect the interaction of hemodynamics and gas exchange. By using this model, the changes of pulmonary arterial pressure and right ventricular pressure in high altitude, which may cause mountain sickness, are discussed. Therefore, this model may be used to study reaction of hypoxia and the assist technologies.

Prediction of Major Pollutants Emission in Direct-Injection Dual-Fuel Diesel And Natural-Gas Engines
The dual-fuel diesel engine (D.F.D.E) is a conventional diesel engine in which much of the energy released, hence power, comes from the combustion of gaseous fuel such as natural gas. The exhaust emission characteristics of the D.F.D.E needs further refinements, particularly in terms of reduction of Unburnt Hydrocarbons (U7HC) and Carbon Monoxide (CO) emission, because the concentration of thes...

Unobtrusive in-home computer monitoring could one day be used to deliver cost-effective diagnostic information about the cognitive abilities of the elderly. This could allow for early detection of cognitive impairment and would additionally be coupled with the cost advantages that are associated with a semi-automated system. Before using the computer usage data to draw conclusions about the par...
متن کاملMultiple modeling in the study of interaction of hemodynamics and gas exchange
Circulation plays an important rule in gas exchange. Therefore, there is an interaction between circulation and gas exchange. To understand the dynamic effect of these two physiological systems, a computer simulation model of hemodynamics and gas exchange is established in this work. This model includes two physiological systems, namely the respiratory and circulatory systems. It consists of fi...

In this paper an artificial society is being assumed as a multi agents system. A sugarscape model consisting of a cellular landscape of resources is used to form an interaction among the agents of the population. In the model, agents find the resources to survive. They are supposed to move and search and because of this movement, an evolutionary social behavior will develope. From model analys...
