Research ArticleOpen accessIn the abstractPatient Data Integration: A Panacea for Effective HealthcareHenry Anayo Okemiri, Alo Uzoma Rita, Achi Ifeany Isaiah et al.A huge challenge in the healthcare domain has remained the spread and proliferation of fragmented information systems and multiplicity of data that accumulate from growing quantities of heterogeneous data of patient. This challenge must be addressed as the whole domain gradually transforms into models of delivery of healthcare that is electronic and patient-centered. The presence of inadequate data integration at … …Journal of Computer Science, Vol. 16, Issue 2 · 22 Feb 2020 · 7,732 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis of Optimal Incoherent Subcarrier Tracking of BOC(1,1) Navigation SignalsAlexandr Ivanovich PerovNavigation receivers of global positioning systems that are operated in complex electromagnetic environment must have an increased noise immunity characteristic. One way of such noise immunity rising is to use incoherent operating mode of navigation receiver. There are known processing algorithms for navigation signals with Binary Phase Shift Keying (BPSK) modulation. But in the near-term outlook Global Navigation Satellite Systems … …American Journal of Applied Sciences, Vol. 13, Issue 9 · 26 Sep 2016 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractOccupational Safety and Health in Tunnelling in Rocks Formations Potentially Containing Asbestos: Good Practices for Risk Assessment and ManagementDavide Labagnara, Mario Patrucco, Achille SorliniIn tunnelling operations, Occupational Safety and Health (OS&H) and Environmental Protection of the areas close to the tunnel portal become even more critical in case of rock formations potentially containing asbestos, quartz, radioactive elements, etc. In order to limit the workers’ exposure and the environmental impact becomes in these cases of paramount importance to preliminarily analyze and quantify the possible … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 26 May 2016 · 7,653 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Handover in WiMax with TCP and UDP as Underlying ProtocolKaram Dhafer Mayoof, Rosilah Hassan, Amjed Sid Ahmed, Ahmed MarwanThe rejection of an ongoing connection/session is serious problem and it degrades the QoS and efficiency of the network rather than rejecting a request for new connection. The impact on performance of handovers is a serious problem in cellular systems that must be addressed. During handover there may be delay in packets and connections may drop. Real time applications i.e., … …Journal of Computer Science, Vol. 11, Issue 9 · 12 Dec 2015 · 7,249 accessesView PDFCite
Research ArticleOpen accessIn the abstractCyclic Prefix Length Determination for Orthogonal Frequency Division Multiplexing System over Different Wireless Channel Models Based on the Maximum Excess Delay SpreadAmar Al-Jzari, Kostanic IvivaCyclic Prefix (CP) is one of the key OFDM parameters. It is used to completely eliminate both Inter-Symbol Interference (ISI) and Inter-Carrier Interference (ICI) as long as the CP length is greater than the channel delay spread. By eliminating the ISI and ICI, the CP compensates for the effect of the multi-path dispersion; but it consumes a considerable amount of … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 13 Apr 2015 · 8,570 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVING THE PERFORMANCE AND REDUCING BIT ERROR RATE ON WIRELESS DEEP FADING ENVIRONMENT RECEIVERSK. Jayanthi, V. P. Arunachalam, C. VasanthanayakiOne of the major challenges in wireless communication system is increasing complexity and reducing performance in detecting the received digital information in indoor and outdoor Environments. Consequently to overcome this problem we analyze the delay performance of a multiuser with perfect channel state information transmitting data on deep fading environment. In this proposed system, the Wireless Deep Fading Environment (WDFE) … …Journal of Computer Science, Vol. 10, Issue 3 · 29 Nov 2013 · 7,103 accessesView PDFCite
Research ArticleOpen accessIn the abstractVLSI Implementation of FIR Filter Using Computational Sharing Multiplier Based on High Speed Carry Select AdderS. Karunakaran, N. KasthuriRecent advances in mobile computing and multimedia applications demand high-performance and low-power VLSI Digital Signal Processing (DSP) systems. One of the most widely used operations in DSP is Finite-Impulse Response (FIR) filtering. In the existing method FIR filter is designed using array multiplier, which is having higher delay and power dissipation. The proposed method presents a programmable digital Finite Impulse … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 5 Jan 2013 · 7,187 accessesView PDFCite
Research ArticleOpen accessIn the abstractVideo Streaming in Peer-to-Peer Networks Using Network Coding Renders Efficient Video Cassette Recorder OperationsR. Arockia Xavier Annie, K. V. Pradeepthi, P. YogeshProblem statement: Major technological development in recent years has led to the usage of shared streaming solutions by Peer-to-Peer (P2P) Video-on-Demand (VoD) systems in the Internet. Video streaming in P2P network systems has ample amount of loss of video packets due to network disabilities such as congestion, intrusion, connectivity problems, excessive network collisions etc. Adding onto the video streaming problems, … …Journal of Computer Science, Vol. 8, Issue 10 · 24 Aug 2012 · 6,744 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime-Delay Estimation using the Characteristic Roots of Delay Differential EquationsSun Yi, Wonchang Choi, Taher Abu-LebdehProblem statement: For ordinary dynamic systems (i.e., non-delayed), various methods such as linear least-squares, gradient-weighted least-squares, Kalman filtering and other robust techniques have been widely used in signal processing, robotics, civil engineering. On the other hand, time-delay estimation of systems with unknown time-delay is still a challenging problem due to difficulty in formulation caused. Approach: The presented method makes use … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 7 Apr 2012 · 8,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of an Error Tolerant AdderA. N. Jayanthi, C. S. RavichandranProblem statement: In modern VLSI technology, the occurrence of all kinds of errors has become inevitable. By adopting an emerging concept in VLSI design and test, Error Tolerance (ET), a novel Error-Tolerant Adder (ETA) is proposed. The ETA is able to ease the strict restriction on accuracy and at the same time achieve tremendous improvements in both the power consumption … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 13 Mar 2012 · 7,256 accessesView PDFCite
