Abstract: The performance of a mechanical or structural system can be improved through a proper selection of its design parameters such as the geometric dimensions, external actions (loads), and material characteristics. The computation ...

Abstract: Several methods are presented for the modeling and analysis of uncertain beams and other structural elements/systems. By representing each uncertain parameter as an interval number, the vibration problem associated with ...

Abstract: A new finite element method is presented for the analysis of uncertain heat transfer problems using universal gray number theory. The universal gray number representation involves normalization of the uncertain parameters ...

Abstract: A threedimensional, singlephase, multicomponent mathematical model is used for the analysis of a liquidfed direct methanol fuel cell. Liquid phase is considered on the anode side, and gas phase is considered on the cathode ...

Abstract: The multiobjective optimum design of stationary compound parabolic concentrator (CPC) solar collectors is considered. The clear day solar beam radiation and diffuse radiation at the location of the solar collector are ...
