Abstract: Through the use of active controllers, a structure can modify its behavior during dynamic loadings such as impact, wind, or earthquake loadings. Such structures with self-modification capabilities are called smart structures. ...

Abstract: Robust and efficient parallel-vector algorithms are presented for the solution of the Riccati equations encountered in optimal control problems on shared-memory multiprocessor machines. The algorithms have been implemented ...

Abstract: In a recent article, the authors presented the formulation and outline of parallel algorithms for the integrated structural/control optimization problem. The solutions of the Riccati equation, open-loop system of equations, ...

Abstract: Various multitasking approaches are investigated for optimization of large space structures. Judicious combination of microtasking, macrotasking, and autotasking is explored with the goal of achieving a vectorized and ...

Abstract: Optimization of combined structural and control systems is a complex problem requiring an inordinate amount of computer‐processing time, especially the solution of the eigenvalue problem of a general unsymmetric square ...

Abstract: The focus of this paper is to present a control methodology for the regulation of loading and processing of parts in a manufacturing cell in the presence of minor disturbances. The control ...

Abstract: In this work central bursting in drawing and extrusion of metals is investigated. The analysis is based on a modified stress distribution within the die zone due to Shield (, 1955, J. Mech. ...

Abstract: In the current study, dustfall during 2019 was collected at 10 sites in Cairo, Egypt, to analyze the metal contents and assess the rate of metal deposition as well as the risks of exposure to metals by analyzing the results ...

Abstract: Heavy metals in deposited dust at five urban districts in Cairo, Egypt, during 2015 were studied. Risk assessment modeling was applied to evaluate health risks of these metals for adults and children. The results show that ...

Abstract: This study evaluates the behavior of fiber-reinforced asphalt mixtures using advanced material characterization and performance prediction models. The polymeric nature of the proprietary blend of polyolefin and aramid ...
