In this paper, slewing maneuver of a flexible spacecraft with large angle of rotation is considered and assuming structural frequency uncertainties a robust minimum-time optimal control law is developed. Considering typical bang-bang control commands with multiple symmetrical switches, a parameter optimization procedure is introduced to find the control forces/torques. The constrained minimizat...

this article aims to analyze the importance of labeling, structural, rational choice and control theories to predict part and partially the re-prison rate. the method is survey and respondents involved the prisoners of at least two record of accusation. sample size amounts 340 prisoners including 98 female and 242 male who were selected by using stratified, systematic and random strategies from...

performance measure approach (pma) is a method for evaluating the probabilistic constraints in reliability-based design optimization of structures. the advanced mean-value (amv) method is suitable for pma, simply and efficiently. the iterative amv scheme could be yielded to unstable solutions such as periodic-oscillation and chaos for highly nonlinear performance functions. in the present paper...

t years, considerable attention has been paid to research lopment of structural control devices, with particular emn alleviation of wind and seismic response of buildings ges. In both areas, serious efforts have been undertaken in wo decades to develop the structural control concept into ble technology. Full-scale implementation of active conms have been accomplished in several structures, main...

The structure–function relationships of a series of bistable [2]rotaxane and [2]pseudorotaxanebased devices have been evaluated across different length scales. The switching characteristics of bistable [2]rotaxanes and self-assembled [2]pseudorotaxanes, which can be controlled chemically, electrochemically, or photochemically, enable them to function as prototypes of molecular machines. The swi...

For smooth and efficient motor control, the brain needs to make fast corrections during the movement to resist possible perturbations. It also needs to adapt subsequent movements to improve future performance. It is important that both feedback corrections and feedforward adaptation need to be made based on noisy and often ambiguous sensory data. Therefore, the initial response of the motor sys...
