In this paper, a novel idea to prepare indoor fresh air by an environmentally friendly way is proposed. In this design we are inspired by traditional windcatchers which have been being used for centuries in torrid region of Iran. Theirs unique feature of in-dependency to costly energy sources have made them suitable choices specially for not fully developed areas. We devised an intelligent windcatcher which can adapts itself according to outside weather conditions to maximize the performance of indoor air conditioning. Design procedure in addition to simulation results are presented and the advantages of the proposed design are discussed.
This paper details the infinite dimensional dynamics of a prototype microfluidic thermal process that is used for genetic analysis purposes. Highly effective infinite dimensional dynamics, in addition to collocated sensor and actuator architecture, require the development of a precise control framework to meet the very tight performance requirements of this system, which are not fully attainable through conventional lumped modeling and controller design approaches. The general partial differential equations describing the dynamics of the system are separated into steady-state and transient parts which are derived for a carefully chosen three-dimensional axisymmetric model. These equations are solved analytically, and the results are verified using an experimentally verified precise finite element method (FEM) model. The final combined result is a framework for designing a precise tracking controller applicable to the selected lab-on-a-chip device.
