Research ArticleOpen accessPhrase in the titleTask Scheduling in Real Time Systems with Energy Harvesting and Energy MinimizationArvind Kumar, Bashir AlamEnergy is a major concern in battery operated real time devices (e.g. sensor nodes situated in remote areas) as battery life is solely responsible for the functioning of such devices. For such systems to work continuously and successively a regular source of energy is required. The lifetime of such systems can be increased by reducing the energy consumption and increasing … …Journal of Computer Science, Vol. 14, Issue 8 · 15 Aug 2018 · 8,287 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVolatility-Aware Hybrid Memory Architecture for Real-Time and Persistent Big Data SystemsMohammed Elhabib Maicha, Mohammed Redha BouzidiAs data volumes and real-time analytics demands grow, DRAM only memory systems struggle to scale cost-efficiently and sustainably. We present VA-HMA, a volatility-aware hybrid memory architecture that combines DRAM and Non-Volatile Memory (NVM) with a lightweight, machine-learned placement layer and endurance-aware fault tolerance. VA-HMA continuously monitors access patterns and applies a Random Forest–based predictor to guide batched page migrations and … …Journal of Computer Science, Vol. 22, Issue 6 · 27 Jun 2026 · 1,214 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Vision-Based Approach to Real-Time Trust Evaluation within Multiagent SystemsAlan Kruger, Sun YiAs robotic autonomy increases, single-agent systems are evolving into more complex multiagent systems that require more factors for successful implementation. In exchange for this complexity, applications such as autonomous delivery services and reconnaissance swarms become possible when they are infeasible with only one agent. By incorporating Trust into the multiagent system, the complexity of the agent-to-agent relationships can be managed … …Journal of Mechatronics and Robotics, Vol. 9, Issue 1 · 21 Mar 2025 · 7,937 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn Optimistic Concurrency Control for Real-Time Database SystemsAmer A. AliThe performance of database transaction processing system can be profoundly affected by the concurrency control method employed since it is necessary to preserve database integrity in a multi-user environment. In addition to satisfying the consistency requirement as in traditional database system, real-time database systems must also satisfy timing constraints. In this study we present a virtual run policy for the … …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 6,901 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEfficiency Assessment of Software-Defined Networking for Real-Time Network SystemsNeelam Gupta, Sarvesh Tanwar, Sumit BadotraSoftware Networking (SDN) is growing in popularity due to its benefits, which include portability, mobility, analytics, and ease of creation. But it needs to be adequately shielded from security risks. One of the main vulnerabilities to the SDN network is the Distributed Denial-of-Service (DDoS) attack. To fulfill the demands of the complex and demanding security concerns of today, a new … …Journal of Computer Science, Vol. 20, Issue 6 · 8 Apr 2024 · 4,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCodesign 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 keywordsAn Experimental Study on the Embedded Software Development Approach Using TI-RTOSAloysio Augusto Rabello de Carvalho, Luiz Eduardo Galvão MartinsEmbedded systems have experienced significant growth in recent years. These systems, which power a wide range of devices from smart appliances to industrial machinery, have become integral to our daily lives and industries. However, this rapid expansion introduces new challenges for developers. A critical decision involves whether to employ a Real-Time Operating System (RTOS) or to forgo it, depending on … …Journal of Computer Science, Vol. 21, Issue 6 · 17 Jul 2025 · 3,068 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFeasibility Analysis of Non-Preemptive Periodic Systems from Infeasibility PerspectiveNasro Min-AllahDue to simple implementation, non-preemptive scheduling has the advantage over preemptive counterpart when it comes to deployment of real-time systems. Accordingly, many feasibility techniques have been established to answer schedulability of the task set for non-preemptive case. The time complexity of exact condition for non-preemptive under dynamic priority assignment is of pseud-polynomial nature. Recently, efforts are made to decrease the … …Journal of Computer Science, Vol. 15, Issue 9 · 9 Sep 2019 · 7,617 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntegrating Lowest Priority Approach with Largest Point Scheme for Faster Feasibility AnalysisNasro Min-AllahRecently many solutions have been proposed to lower the computational cost of feasibility analysis for real-time systems. The computational cost of feasibility tests can be lowered by strategies such as lowering the number of scheduling points needed during analysis, starting feasibility analysis from lowest priority, or starting schedulability tests for a task with larger scheduling point. All these techniques significantly … …Journal of Computer Science, Vol. 15, Issue 4 · 26 Apr 2019 · 7,247 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExtending UML-RT for Control System ModelingQimin Gao, L. J. Brown, L. F. CapretzThere is a growing interest in adopting object technologies for the development of real-time control systems. Several commercial tools, currently available, provide object-oriented modeling and design support for real-time control systems.
