NLO QCD fits using the DGLAP formalism have been made to the high precision ZEUS ep reduced cross-section data and to fixed target structure function data, in order to determine parton distribution functions and the value of αs(M 2 Z), taking full account of correlated systematic errors. The new high precision ZEUS data on the neutral current e+p reduced cross section [1] are fit to the predict...

În cadrul acestei lucrări sunt explorate soluţii de aplicare a specificaţiilor IEC 61499 în modelarea şi implementarea controlului de nivel înalt al holonilor. Conceptele IEC 61499 au fost utilizate ca o tehnologie suport pentru încapsularea controlului inteligent al holonilor, modelarea comunicaţiei interholonice şi configurarea dinamică a holonilor. Modelele şi teoriile propuse au fost valida...

One of the goals of introducing computers to the classroom is to support students who are more reluctant to the use of technology or who do not have a computer at home in acquiring computer literacy. Studies have shown that these students are often girls. The goal of the present study is to find out if the difference between boys and girls in computer literacy can be leveled out in a laptop pro...

A sensor for rapid (10 msec response time) measurement of vapors from the hydrocarbon-based fuels JP-8, DF-2, and gasoline is described. The sensor is based upon a previously reported laser mixing technique that uses two tunable diode lasers emitting in the near-infrared spectral region [1] to measure concentrations of gases having unstructured absorption spectra. The fiber-mixed Published in A...

IONS OF HAMILTONIAN CONTROL SYSTEMS PAULO TABUADA AND GEORGE J. PAPPAS Abstra t. Given a ontrol system and a desired property, an abstra ted system is a redu ed system that preserves the property of interest while ignoring modeling detail. In previous work, we onsidered abstra tions of linear and analyti ontrol systems while preserving rea hability properties. In this paper we onsider the abstr...

La Teoría de Diseño de Sistemas de Información, es una metodología propuesta por Walls y Widmeyer (1992) que consiste en un conjunto de teorías descriptivas, que ofrecen principios y guías que permiten dar soluciones a los desarrolladores y diseñadores de sistemas, buscando lograr el diseño de herramientas de software que sean incluyentes, flexibles y que estén estrechamente integradas con las ...
