The problem of disturbance rejection in the control of nonlinear systems with additive disturbance generated by some unforced nonlinear systems, was formulated and solved by {itshape Mukhopadhyay} and {itshape Narendra}, they applied the idea of increasing the order of the system, using neural networks the model of multilayer perceptron on several systems of varying complexity, so the objective...

in this paper, we introduce environmental systems engineering (ese) and describe some of its applications combined with process systems engineering (pse) to problems related to environmental systems. these systems—the water cycle and ecosystem cycles—are complex and highly dynamic, with an uncertainty level comparable to that of chemical systems. to illustrate the challenges of applying pse to...

Laricobius nigrinus Fender (Coleoptera: Derodontidae) is a specialist predator of the hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), native to the Pacific Northwest. It has been introduced into the eastern United States for biological control of exotic hemlock woolly adelgid populations that threaten native hemlock. The possible role of olfactory cues in host finding by t...

We studied the adult ambulatory response of the predator, Laricobius nigrinus Fender (Coleoptera: Derodontidae), to odors from its prey, Adelges tsugae Annand, the hemlock woolly adelgid, and foliage of hemlock woolly adelgid, host hemlocks (Tsuga spp.), and other conifers. Both the predator and hemlock woolly adelgid are apparently native to western North America, but the predator is being re...

IT is generally accepted that fractures into joints must, if possible, be afforded perfect reduction, and that when accurate reduction has not been achieved, some considerable stiffness and degenerative arthritis may confidently be expected. This was once commonly illustrated by the malunited fracture-dislocation of the ankle, and incongruities of the scaphoid, olecranon and acetabulum provoke ...

I partially review our current knowledge on microquasars, making special emphasis on radio interferometric observations, and I comment on emerging trends in this field of astrophysics. 1. X-ray binaries, radio emission and microquasars An X-ray binary is a binary system containing a compact object, either a neutron star or a stellar-mass black hole accreting matter from the companion star. The ...

The black hole candidate (BHC) X-ray transient 4U 1630–47 continuously produced strong X-ray emission for over 2 years during its 2002–2004 outburst, which is one of the brightest and longest outbursts ever seen from this source. We use over 300 observations made with the Rossi X-ray Timing Explorer (RXTE) to study the source throughout the outburst along with hard X-ray images from the INTErna...

introduction: implementation of hospital information system (his) depends on the complete organizational change in which most effective factors need to be considered. since the most important factor is human resources, training, survey, information and acceptance of the staff toward the his are also essential issues. we investigated the implementation of his in imam khomeini hospital. methods: ...
