Probably the most popular algorithm for unconstrained minimization for problems of moderate dimension is the Nelder-Mead algorithm published in 1965. Despite its age only limited convergence results exist. Several counterexamples can be found in the literature for which the algorithm performs badly or even fails. A convergent variant derived from the original Nelder-Mead algorithm is presented....

A set S of vertices in a graph G(V,E) is called a total dominating set if every vertex v ∈ V is adjacent to an element of S. A set S of vertices in a graph G(V,E) is called a total restrained dominating set if every vertex v ∈ V is adjacent to an element of S and every vertex of V − S is adjacent to a vertex in V − S. The total domination number of a graph G denoted by γt(G) is the minimum card...

Interdigitated finger (comb) structures are demonstrated to be effective for exciting electrostatically the resonance of polysilicon microstructures parallel to the plane of the substrate. Linear plates suspended by a folded-cantilever truss and torsional plates suspended by spiral and serpentine springs are fabricated from a 2/~m-thick phosphorus-doped low-pressure chemical-vapordeposited (LPC...

OBJECTIVE Relationships were studied between emotional, external and restrained eating behavior, and bulimia, and also between these types of eating behavior and body dissatisfaction and drive for thinness. METHOD The sample consisted of female adolescents. Eating behavior and body evaluation were measured with scales of the Dutch Eating Behaviour Questionnaire (DEBQ) and the Eating Disorders...

Associative color learning has been demonstrated to be very poor using restrained European honey bees unless the antennae are amputated. Consequently, our understanding of proximate mechanisms in visual information processing is handicapped. Here we test learning performance of Africanized honey bees under restrained conditions with visual and olfactory stimulation using the proboscis extension...

The present study was designed to monitor the responsiveness of 5-hydroxytryptamine (5-HT; serotonin)-2C receptors following the exposure to restraint stress in rats. Rats were restrained for 2 hours. 24-h after the termination of the restraint period, 1-(m-Chlorophenyl)piperazine (m-CPP; a 5-HT-2C agonist) at the doses of 1.5 mg/kg or 3.0 mg/kg and saline (1 ml/kg), was injected to unrestraine...
