Abstract: A combination of the first and second laws of thermodynamics has been utilized in analyzing the performance of a double pipe heat exchanger with a porous medium attached over the inner pipe. ...

Abstract: We consider the problem of designing robust tracking controllers for uncertain fully-actuated mechanical systems. We propose controllers which are robust r − α tracking controllers in the following ...

Abstract: Due to construction, operation, and maintenance difficulties, usually installing very wide sluice gates in open channels is not recommended. Instead, multiple parallel gates have been used in such circumstances, which ...

Abstract: This paper presents an experimental study of solar hydrogen production via electrolysis of water (conversion of solar energy into chemical energy), and thus, a direct link between the electrolyser (Hoffman voltammeter) and ...

Abstract: This paper aims to investigate the effects of using palm leaves ash, when it partially replaces the concrete cement content, to treat the effects of using seawater as a mixing water and curing water on concrete. The paper ...

Abstract: AbstractThis research study investigated the axial load and fiber alignment effects in the shear behavior of Ultrahigh-Performance Concrete (UHPC) panels incorporating reinforcing bars. Three UHPC panels were tested on the ...

Abstract: The objective of this work is to develop a multiscale modeling tool of copolymers with long chains. We propose an enhanced coarse-graining method of thermoplastic polyurethane (TPU) with three beads. The proposed coarse-graining ...

Abstract: The shortest route from home to work may not be the best alternative, and a longer route may be fastest or safest. Hence, the best route reflective of one factor may not be the ultimate best alternative. This paper discusses ...
