Research ArticleOpen accessIn the keywordsA New Approach for Sub-Channels Assignment in Downlink Fourth Generation Mobile SystemsFakhreddine Khelifa, Abdelaziz SametProblem statement: We proposed a new heuristic method for subchannels allocation problem in the context. Approach: In this system, OFDM transmission method has been used, in order to reduce the effect of multipath fading, OFDMA to achieve multiple access schemes and flexibility in resource allocation. Results: An adaptive method for subchannels allocation is necessary in order to exploit the multiuser … …Journal of Computer Science, Vol. 7, Issue 9 · 23 Jul 2011 · 6,588 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUnequally Error Protected Wireless Data Transmission Using Channel State Information and Adaptive EncodersYaseen H. Tahir, Chee Kyun Ng, N. K. Noordin et al.Problem statement: Higher data transmission rate with Quality of Services (QoS) guarantee is an important objective for wireless broadband communication systems. Unlike other communication system, real-time transmission requires high data rate and good error performance to ensure good quality of service. This study describes the design problem of real-time wireless data transmission which provides higher achievable data rate with Unequal … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,250 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInsulin Pump Therapy in Type 1 Diabetes-Merging Technology with Diabetes CareH. ThabitThe use of insulin pump therapy has been increasing over the past number of years in many countries. The Diabetes Control and Complications Trial (DCCT) have proven that better glycaemic control with fewer hypoglycemic events is achievable with insulin pump therapy. The delivery of subcutaneous insulin through an insulin pump mimics physiological insulin delivery better than Multiple Daily Injection of … …Current Research in Medicine, Vol. 3, Issue 2 · 22 May 2012 · 7,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of Novel Gated Integrator for the Heavy ion Beam Monitors SystemDjamet Yimga Arnaud, Wembe Tafo Evariste, Essimbi Zobo BernardIn this study, the objective is to realize a Gated Integrator (GI) circuit for silicon strip, Si(Li), CdZnTe and CsI detectors etc. With the development of radioactive ion beam physics, heavy-charged particles like carbon ions have been applied to the treatment of deep-seated inoperable tumors in the therapy terminal of the Heavy ion Research Facility in Lanzhou (HIRFL) located at … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 27 Feb 2017 · 7,174 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cross Layer Frame Work for Enhanced Quality of Service Provisioning in Worldwide Interoperability for Microwave Access NetworksS.J.K. Jagadeesh Kumar, T. PurusothamanProblem statement: The demand for multimedia applications in WiMAX networks is growing at a rapid pace. A method for guaranteeing Quality of Service (QoS) for different classes of traffic is therefore gaining importance. Hence designing and analyzing multimedia traffic and QoS parameters has become central to this problem. In this study, we propose a cross layer frame work in which … …Journal of Computer Science, Vol. 8, Issue 3 · 21 Jan 2012 · 7,052 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduced Order Models of a Current Source Inverter Induction Motor DriveIbrahim K. Al-AbbasProblem Statement: The current source inverter induction motor (CSI-IM) drive was widely used in various industries. The main disadvantage of this drive was nonlinearity and complexity. This work was done to develop a simple drive systems models. Approach: The MATLAB/SIMULINK software was used for system modeling. Three reduced models were developed by choosing specific frame, neglecting stator transients and ignoring … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 7,865 accessesView PDFCite
