The widespread integration of virtualization technologies in data centers has enabled in the last few years several benefits in terms of operating costs and flexibility. These benefits maybe boosted through join optimization of power management (PM) and dependability for virtualized systems. This indeed involves developing appropriate models to better understand their performability behavior wh...

This study aims to explore the critical driving and resisting forces that promote or inhibit the implementation and use of project management (PM) software in Qatari Government Organizations in an attempt to determine whether software-based PM methodologies are being effectively implemented in the public sector organizations or not. Research hypotheses were evaluated using ANOVA and MannWhitney...

In this paper a fast analytical algorithm for design a surface-mounted PM Brushless DC motor (SMPM-BLDC) for variable-speed application based on electromagnetic field analysis and RSM optimization algorithm is discussed. To achieve the desired performance, the physical dimensions of the proposed SMPM-BLDC motor subject to minimal ripple torque utilizing RSM optimization algorithm were optimized...

A large nurober of investigations have been undertaken to develop technical systems in order to enable a tactile substitution of speech for the deaf. These aids have been evaluated with various experimental procedures (identification and discrimination tests, learning experiments, tracking procedures and other overt behaviour methods). In order to find additional evidence for the processing and...

Nasal nitric oxide (nNO) has been suggested as a valuable marker of upper airway infl ammatory diseases, especially allergic rhinitis [1-3]. In order to interpret nNO values derived from single measurements, knowledge about a potential diurnal variation is mandatory. The existing data, however, do not yield a consistent picture [4-6]. The aim of this study was to assess the presence of diurnal ...

Prospective memory (PM) is the ability to remember to carry out intended actions in the future. Empirical evidence suggests that PM deficits exist in individuals with chronic schizophrenia. However, it is unclear whether PM deficits in first-episode schizophrenia exist independently from other neuropsychological deficits. Moreover, prior research using patients with first-episode has been limit...

The unquenchable demand for rock materials has attracted many companies within the building and construction sector to invest in stone quarrying. However, this brought about environmental impacts with health threats people. There is a paucity of information magnitude pollution on air water how it varies quarry sites. This study, therefore, investigated physical quarrying explored in-situ mitiga...

Aim: This work investigates the correlation between the cardiac electrical activity underlying spontaneous ventricular tachyarrhythmias and their modes of onset. Signals: We analyzed 81 episodes of spontaneous ventricular tachycardia (VT) and ventricular fibrillation (VF) lasting at least 5 seconds from 17 patients. The cardiologist classified VT/VF malignancy by considering fast VT as more mal...
