Obstacle crossing challenges balance and increases the risk of falls in older people. Knowledge control strategies adopted by people will be helpful for study mechanisms during obstacle development fall-prevention approaches. A mechanical model body combined with measured gait data was used to 17 healthy young adults when obstacles different heights, terms best-compromise weighting sets objecti...

this paper represents a complete survey on generation companies’ (gencos’) optimal bidding strategy problem in restructured power markets. in this regard after an introduction to competitive electricity markets, concept of optimal bidding strategy is presented. considering large amount of works accomplished in this area a novel classification is implemented in order to categorize the existing d...

The paper provides a framework for addressing the question of when transactions should be carried out within the firm and when through the market. Following Grossman and Hart (1986), we identify a firm with the assets which its owners control: ownership confers the right to decide how the assets are to be used in events unspecified in an initial contract. We study how changes in ownership affec...

Abstract: The robust control problem for linear systems with parameter uncertainties and time-varying delays is examined. By using an appropriate uncertainty description, a linear state feedback control law is found ensuring the closed-loop system’s stability and a performance measure, in terms of the guaranteed cost. An LMI objective minimization approach allows to determine the ”optimal” choi...
