Research ArticleOpen accessEvery word in the titleHandover Outage Time Optimization in Heterogeneous NetworksS. LouvrosHandover is a very critical parameter in Cellular Networks. The outage handover time is a drawback for Quality of Service in wireless voice applications and heterogeneous cellular wireless networks. Apart from existing handover technique, a novel approach has been developed known as Network Assisted Handover improving the outage handover time and the fluctuations of data throughput. …Journal of Computer Science, Vol. 3, Issue 11 · 30 Nov 2007 · 6,551 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudies on the Influence of Various Blade Outlet Angles in a Centrifugal Pump when Handling Viscous FluidsM.H.S. Fard, F.A. BoyaghchiIn this study the centrifugal pump performances with different blade outlet angles are tested when handling water and viscous oils as Newtonian fluids. Also, this study shows a numerical simulation of the three-dimensional fluid flows inside the centrifugal pump with different blade outlet angles. For these numerical simulations the SIMPLEC algorithm is used for solving governing equations of incompressible viscous/turbulent … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 7,706 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCustom Design of an Analogue Input Digital Output Interface Card for Small Size PLCsMohammad A.K. AliaThis paper describes the design and implementation of an interface card (IC) with analogue input and digital output, designed for use with small size PLCs, which do not support interface features. The absence of generic I/O interface modules due to the differences in PLCs design and software, validates the importance of such work. The IC costs about one third of … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,442 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of Output Codes for Fast Covering Learning using Basic Decomposition TechniquesAruna Tiwari, Narendra S. ChaudhariWe propose the design of output codes for solving the classification problem in Fast Covering Learning Algorithm (FCLA). For a complex multi-class problem normally the classifiers are constructed by combining the outputs of several binary ones. In this paper, we use the basic methods of decomposition; one per class (OPC) and Error Correcting Output Code (ECOC) with FCLA, binary to … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,302 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAntecedents and Outcomes of Organisational Commitment among Malaysian EngineersRajendran Muthuveloo, Raduan Che RoseThis study explores the major factors contributing to organizational commitment among engineers in Malaysia. It identifies the effects of certain antecedents on organizational commitment and evaluates the impact of organizational commitment to organizational outcomes. From the literature review, a theoretical foundation for the study was compiled and two hypotheses were established. Firstly, positive employee perception leads to higher organizational commitment. … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,488 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImproved Performance of Traffic Dependent Outage Rate Cellular SystemHussein M.A. Basi, M. B.R. MurthyThe designers of a mobile cellular system must evaluate the possible configurations of the system components and their characteristics in order to develop a system with greater efficiency. The useful parameters to estimate performances of the system are voice quality, frequency spectrum efficiency and grade of service (GOS). In this study, a scheme proposed to reduce the lost calls and … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,812 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Analysis of the Output and Employment Conversion Matrices of Australia's EconomyAbbas Valadkhani, Tim RobinsonBased on two snapshots taken from the Australian economy, this study quantifies the impacts of final demand aggregates on output and employment in various sectors using the 1989 and 1997 conversion matrices. The sectoral output and employment are linked with final demand deliveries in such a way that one can measure the impacts on changes in each component of aggregate … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,750 accessesView PDFCite
