Abstract: A hydrophilic expanded poly(tetrafluoroethylene) (ePTFE) based composite membrane was prepared and tested for proton exchange fuel cell applications. The composite membrane was prepared by impregnating ...

Abstract: Hygroscopic and thermal expansion behavior of advanced polymers is investigated when subjected to combined high temperature and moisture conditions. An enhanced experimental–numerical hybrid procedure is proposed to ...

Abstract: Stick-slip is a complex phenomenon which has been studied by researchers from many points of view. A variety of engineering factors, such as surface roughness, may contribute to this behavior. ...

Abstract: The paper presents a numerical solution to the problem of a hot rigid indenter sliding over a thermoelastic Winkler foundation with a thermal contact resistance at constant speed. It is shown ...

Abstract: In this paper, a compensation method of nonlinear friction using online input estimation (IE) method is developed. To illustrate the validity and performance of the proposed algorithm applied to positioning system, comparisons ...

Abstract: The perturbation of the middle cell of the general circulation in a baroclinic atmosphere is investigated under the assumption of horizontal, divergence-free, isothermal motion. With the introduction of the horizontal ...

Abstract: Rheological behavior in concentrated contacts has been studied extensively. In certain conditions such as a rough concentrated contact or sliding of nominally flat surfaces, films may be of ...

Abstract: The purpose of this paper is to determine the natural frequencies and mode shapes of beams carrying any number of two-degree of freedom (DOF) spring-mass systems by means of two finite element methods FEM1 and FEM2. For ...

Abstract: Simple or complex travel patterns, performed as activities, are linked, and various travel modes are used. Individuals try to link several trips as a type of chain to save transportation resources, such as travel distance ...

Abstract: Count data models are established to overcome the shortcoming of linear regression model used for trip generation in conventional four step travel demand forecasting. It should be checked if there are overdispersion and ...
