Approximately 40% of males with the fragile X premutation develop fragile X-associated tremor/ataxia syndrome after age 50. Although the thalamus and basal ganglia play a crucial role in movement disorders, their involvement in fragile X premutation carriers has not been systematically investigated. The current study characterized structural abnormalities associated with fragile X premutation c...

This paper considers the problems of robust non-fragile control for uncertain discrete-delay large-scale systems under state feedback gain variations. Two classes of controller gain variations are considered. Based on the Lyapunov method, the state feedback control design for robust stability is given in terms of solutions to a linear matrix inequality (LMI). The solutions of the LMI can be eas...

Non-fragile fault-tolerant controller is designed for a class of linear uncertain time-delayed systems. Two cases of controller perturbation are investigated in view of different application conditions. One case is the controller gain attenuation, the other is random uncertainty caused by noise possibly existing in an industrial field. The controller to be designed can guarantee systems to have...

The problem of robust and non-fragile control by static state feedback gains assuring both the H∞ guaranteed cost and regional pole location of the closed loop eigenvalues is proposed in this paper, for uncertain discrete-time system with multiple delays in the states. The regional pole location, or the D-stabilization, concerns with the problem of locating the closed-loop system eigenvalues in...

Absbrrcf-TIIe paper proposes a new fragile image watermarking scheme b a d on time-frequency analysis S p e d i d y , the watermark is ehps an arbitrary non-stationary signal with a particular signature in the time-frequency plane. The proposed technique retains a hi& quality watermarked image since only a few pixels of the original image are used in the watermarking process. Experimental resul...

Due to both internal and external factors, Western Asia has long been suffering from security problems and political instability. The institution of various military and militia groups in the region in the absence of powerful central governments is the focal point of the crises, where the internal and external factors meet. The development of such security and military interactions outside the ...
