We present recent results on elastic and inelastic low/medium energy electron interaction with tetrahydrofuran, C4H8O, tetrahydrofurfuryl alcohol, C5H10O2 and 3hydroxytetrahydrofuran, C4H8O2 molecules in gaseous phase. A comparative study of both absolute differential cross sections for elastic electron scattering and electron energy loss spectra, in a wide incident electron energy range from 5...

This paper presents a general framework for optimal task reallocation in heterogeneous distributed computing systems (DCSs). The framework relies on a rigorous analytical model for the stochastic execution time of a workload. The model takes into account the heterogeneity and randomness of both service times and communication delays, an arbitrary task-reallocation policy as well as the stochast...

Abstract We calibrate the distorted wave Born approximation (DWBA) for electron impact excitation processes empirically. Differential cross sections (DCSs) for the excitation of the 2p53s, 2p53p, 2p54s and 2p54p configurations of Ne and the 3p54s and 3p54p configurations of Ar by electron impact are calculated using DWBA for incident energies between 20 and 100 eV. The calculated results are co...

The operational complexity of modern ships requires the use of advanced applications, called damage control systems (DCSs), able to assist crew members in the effective handling of dangerous events and accidents. In this article we describe the development of a knowledge-based decision support system (KDSS) integrated within a DCS designed for a national navy. The KDSS uses a hybrid design and ...

OBJECTIVE To determine ethical implications for nursing practice at the point of decision making by nursing professors in practice area. METHODOLOGY A qualitative method was adopted, with use of semistructured interviews with sixteen nursing professors who delivered care at a teaching hospital in Salvador, Bahia, from May to June 2011. The methodological reference used was the discourse of th...

The purpose of any distributed computing system (DCS) is to offer a flexible, reliable and powerful computing platform. With the advances in mobile computing, wireless communications and sensor networks, DCSs have emerged in new applications such as wireless sensor networks (WSNs), military battlefield awareness, surveillance and threat detection, to name a few. These new application areas intr...

District cooling systems (DCSs) belonging to multi-energy can be managed by model predictive controls (MPCs) designed reduce the amount of electrical energy collected from grid for backup when there is a temporal mismatch between demand and availability. In this paper, DCS recovering cold thermal liquid-to-compressed natural gas fuel station used in an 8-user residential neighborhood provide sp...
