This paper investigates the observer-based non-fragile output feedback tracking control problem for nonlinear networked systems with randomly occurring gain variations. The considered are represented by a Takagi–Sugeno (T–S) fuzzy model. dynamical quantization methodology is employed to achieve reasonable and efficacious utilization of limited communication resources. objective design controlle...

This chapter will consider two discrete time mixed LQR/ H∞ control problems. One is the discrete time state feedback mixed LQR/ H∞ control problem, another is the non-fragile discrete time state feedback mixed LQR/ H∞ control problem. Motivation for mixed LQR/ H∞ control problem is to combine the LQR and suboptimal H∞ controller design theories, and achieve simultaneously the performance of the...

A hybrid watermark that consists of a robust part and a fragile part can be used to serve multiple purposes. The robust part can protect copyright information, the fragile part can detect tampering, and their combination enables identification of attacks encountered. This paper analyses an overlap and a non-overlap implementation of the robust and fragile parts in a hybrid system. The differenc...

Twelve males with fragile-X syndrome between the ages of three and 28 years underwent assessment of thyroid function. All 12 subjects demonstrated normal baseline values for thyroid stimulating hormone (TSH), thyroxine, thyroid binding globulin (TBG), and estimated free thyroxine (EFT). Relative to a control group reported in the literature, however, the fragile-X subjects exhibited a blunted T...

Averaged across crop, year and season , residue cover reduction was significantly less for coulter-type applicators than for disk-type applica-tors (P<0.001), disk-type applicators reduced residue cover significantly less than chisel and sweep injectors (P<0.001), and chisel and sweep injec-tors reduced residue cover similar to a tandem disk (P=0.398). Ranges of values to estimate the percentag...

The fragile X mutation can now be recognised by a variety of molecular techniques. We report a pilot screening survey of a population of children with mental impairment in which we used Southern blotting methods to detect the fragile X mutation, augmented by cytogenetic studies on children whose phenotype suggested a possible chromosome abnormality. There were 873 children with special educatio...

BACKGROUND Fragile X syndrome is associated with low ovarian reserve and poor ovarian response. The aim of this study was to investigate whether CGG repeats on the fragile X mental retardation 1 (FMR1) gene have predictive value for ovarian response to stimulation with gonadotrophins and for clinical outcome in our oocyte donation program. METHODS Oocyte donor candidates were selected accordi...
