In this paper, the finite-horizon H∞ fault estimation problem is investigated for a class of uncertain nonlinear time-varying systems subject to multiple stochastic delays. The randomly occurring uncertainties (ROUs) enter into the system due to the random fluctuations of network conditions. The measured output is quantized by a logarithmic quantizer before being transmitted to the fault estima...

Aims. The clustering properties of a large sample of U-dropouts are investigated and compared to very precise results for B-dropouts from other studies to identify a possible evolution from z ∼ 4 to z ∼ 3. Methods. A population of ∼ 8800 candidates for star-forming galaxies at z = 3 is selected via the well-known Lyman-break technique from a large optical multicolour survey (the ESO Deep Public...

Mortality disparities between high school dropouts and high school graduates may be widening over time. These changes could simply reflect demographic changes among dropouts over time or could represent changes to the cognitive or social benefits of education itself. We used a unique dataset that contains 32 years of survey data, 38 years of mortality follow-up data, and a wide array of psychol...

PURPOSE To test a socialization model of polydrug use among Mexican-American and white non-Hispanic school dropouts. METHODS A sample of 910 Mexican-American and white non-Hispanic school dropouts were surveyed regarding their use of alcohol, marijuana, and other drugs, and socialization characteristics that have previously been shown to be predictive of adolescent substance use. A structural...

To examine why court mandated offenders dropout of drug treatment and to compare their characteristics, treatment experiences, perceptions, and outcomes with treatment completers, we analyzed self-reported and administrative data on 542 dropouts (59%) and 384 completers (41%) assessed for Proposition 36 treatment by thirty sites in five California counties during 2004. At intake, dropouts had l...

BACKGROUND Efforts to select the appropriate number of implants in adolescent idiopathic scoliosis (AIS) instrumentation are hampered by a lack of biomechanical studies. The objective was to biomechanically evaluate screw density at different regions in the curve for AIS correction to test the hypothesis that alternative screw patterns do not compromise anticipated correction in AIS when using ...

This article under unreliable communication links considers the problem of dynamic compensation output-feedback control for non-linear discrete-time networked systems (NCSs) with packet dropouts in light Takagi-Sugeno (T-S) fuzzy method. Specifically, are modeled by Bernoulli random binary distribution both controller-to-actuator (C/A) and sensor-to-controller (S/C). In addition, to estimate mi...

During the study period of three months, out of 425 patients attending the psychiatric clinic of a general hospital, for the first time, 165 (38.8%) did not complete the treatment as prescribed by the doctors and were considered as dropouts. They were contacted at their homes to find out the reasons of the dropping out, were compared with patients, who completed the treatment fully on socio-dem...
