Research ArticleOpen accessIn the abstractDesign of a Distributed Control System Using a Personal Computer and Micro Control Units for Humanoid RobotsMitsuhiro Yamano, Akihiro Ochiai, Yuichi Suzukawa et al.Problem statement: Humanoid robots have many motors and sensors and many control methods are used to carry out complicated tasks of the robots. Therefore, efficient control systems are required for the robots. Approach: This study presented a distributed control system using a Personal Computer (PC) and Micro Control Units (MCUs) for humanoid robots. Distributed control systems have the advantages that … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Causal Protocol with Forward Error Correction for Mobile Distributed SystemsEduardo Lopez Dominguez, Saul E. Pomares Hernandez, Gustavo Rodriguez Gomez et al.Problem statement: Causal ordering is used in Mobile Distributed Systems (MDS) to reduce the non-determinism induced by four main aspects: host mobility, asynchronous execution, unpredictable communication delays and unreliable communication channels. Some causal protocols have been proposed for MDS. All of these protocols in order to ensure the causal order in unreliable channels use the method of Automatic Repeat Request … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 8,239 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow-Cost Encoding Device for Optical Code Division Multiple Access SystemMohammad Syuhaimi Ab-Rahman, Boonchuan Ng, Norshilawati Mohamad Ibrahim, Sahbudin ShaariProblem statement: Instead of using Fiber Bragg Grating (FBG) to develop the coded spectrums, which consist of expensive elements, the grating also are highly sensitive to environmental changes and this will contribute to the increment of capital and operational expenditures (CAPEX and OPEX). Approach: This study presented the development of low-cost 16-ports encoding device for Optical Code Division Multiple Access … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,638 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Secure Time-Stamp Based Concurrency Control Protocol For Distributed DatabasesShashi Bhushan, R. B. Patel, Mayank DaveIn distributed database systems the global database is partitioned into a collection of local databases stored at different sites. In this era of growing technology and fast communication media, security has an important role to play. In this paper we presented a secure concurrency control protocol (SCCP) based on the timestamp ordering, which provides concurrency control and maintains security. We … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,885 accessesView PDFCite
Research ArticleOpen accessIn the abstractCodesign Methodology of Real-time Embedded Controllers for Electromechanical SystemsSlim Ben Saoud, Andreas Gerstlauer, Daniel D. GajskiUnder increasing time-to-market pressures in the electric drives industries, the development time of new algorithms and new control systems including their debugging time must be minimized. This requirement can be satisfied only by using a well-defined system-level design methodology and by reducing the migration time between the algorithm development language and the hardware specification language. In this study, we propose … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impacts of Total System Design Factors on Human Performance in Power PlantsA. Azadeh, J. Nouri, I. Mohammad FamThe objective of this study is to evaluate the impact of total system design factors (TSD) on human performance in a power plant. The TSD factors are defined as design factors, which have an impact on the overall performance of the power plants in the context of total human engineering or macroergonomy. The systems being studied are the control rooms … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,674 accessesView PDFCite
Research ArticleOpen accessIn the abstractSMART TRAVELLING WITH RADIO FREQUENCY IDENTIFICATIONZainab Rasheed Fahad Mirza, Muhammad Nawaz BrohiRadio Frequency Identification (RFID) technology is being widely used now-a-days and is becoming more popular with every passing day. There are varied applications of this technology in various fields such as industry, communication, travel and transportation. Roads, rail ways, air traffic and container vessel shipping all share underlying abstractions of transportation nets with hubs. This study is concerned with applications … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 7,157 accessesView PDFCite

Research ArticleOpen accessIn the abstractQoS Based IPTV over LTE-WLAN Heterogeneous NetworksMohamed Matoui, Noureddine Moumkine, Abdellah AdibHeterogeneous networks required IP Multimedia Subsystem (IMS) technologies to perform their control signaling and improve their communication services. However, the highest IPTV-QoS cannot be performed using IMS only as it cannot differentiate between IPTV video components. In this paper, we implement our IPTV-flow label technique in LTE-WLAN heterogeneous systems that used to improve QoS by providing IPTV sub traffic priority … …Journal of Computer Science, Vol. 15, Issue 4 · 19 Apr 2019 · 7,628 accessesView PDFCite
