Research ArticleOpen accessIn the keywordsStochastic Model for Pricing Normal Bonds when Maturity Periods Cross Over to Pandemic PeriodSulaiman Sani, Siphelele LushabaIn this study, Ito form for normal bonds trading where maturity periods cross over to COVID-19 pandemic period is presented. It is shown that normal bonds in this period experience path reversals respective to their canonical paths. The criterion used in arriving at this striking result is also presented. As a key recommendation, it is necessary that bondholders enact flexible … …Journal of Mathematics and Statistics, Vol. 19, Issue 1 · 6 May 2023 · 6,100 accessesView PDFCite
Research ArticleOpen accessIn the keywordsOn the Relationship between Classes P and NPAnatoly D. PlotnikovProblem statement: In this study we discuss the relationship between the known classes P and NP. We show that the difficulties in solving problem “P versus NP” have methodological in nature. An algorithm for solving any problem is sensitive to even small changes in its formulation. Conclusion/Recommendations: As we will show in the study, these difficulties are exactly in the … …Journal of Computer Science, Vol. 8, Issue 7 · 16 May 2012 · 10,601 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReliability Equivalence Factors of a System with 2 Non-identical Mixed Lifetimes and Delayed TimeAbdelfattah Mustafa, Adel A. El-FaheemProblem statement: In reliability theory and operations research, there are many methods and techniques to improve the performance of a system. The aim of this study is to generalize reliability equivalence technique to apply it to a mixed failure lifetimes system f1 (t), f2 (t) with delayed time. Approach: We shall improve the system by using some reliability techniques: (i) … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 29 Jul 2011 · 7,550 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReliability Equivalence Factors of a System with m Non-Identical Mixed of LifetimesAbdelfattah Mustafa, Adel A. El-FaheemProblem statement: The aim of this study is to generalize reliability equivalence technique to apply it to a system consists of m independent and non-identical lifetimes distributions, with mixed failure lifetimes f1(t),f2(t),…,fm(t). Approach: We shall improve the system by using some reliability techniques: (i) reducing the failure for some lifetimes; (ii) add hot duplication component; (iii) add cold duplication component; … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,306 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAn Improved TCP Connection Protocol over Wireless Mobile Networks with Mobile Nodes HandoffMaen M. Al AssafProblem Statement: This study proposes a TCP layer protocol (Div-TCP) that aims to give a solution for communication over wireless mobile networks that have the occurrence of handoff at anytime. It describes a topology of wireless mobile network and the handoff process as an ordinary process in that type of networks which may cause segments losses. Approach: Wireless mobile networks … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,678 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFault Detection of Computer Communication Networks Using an Expert SystemIbrahiem M.M. El Emary, Adanan I. Al RabiaThe main objective of this study was to build an expert system for assisting the network administrator in his work of management and administration of the computer communication network. Theory of operation of the proposed expert system depends on using a time series model capable of forecasting the various performance parameters as: delay, utilization and collision frequency. When the expert … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,129 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Bibliometric and Scientometric Analysis of the Marine Biotechnology Research Using CiteSpace: A Web of Science Based Study (1980-2023)Jasnizat Saidin, Idham Sumarto Pratama, Mohamad Nor Azra et al.A growing interest in marine biotechnology has spurred the exploitation of oceanic resources for novel products. However, a comprehensive, data-driven mapping of this evolving landscape remains limited. This study presents a systematic scientometric analysis using CiteSpace to map global research trends and structural knowledge domains in marine biotechnology. Utilizing metadata extracted from the Web of Science Core Collection (WoSCC) database, … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 28 Sep 2026 · 519 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrioritized Experience Replay-Based Deep Deterministic Policy Gradient for Reliable Path Selection in SDN-IoT NetworksGaurav Kumar, G. S. Girisha, N. ShamanthRouting optimization is becoming prominent in Software-Defined Networks (SDN) due to the exponential growth of network traffic demands and the requirement for Quality of Service (QoS). However, reliable routing that satisfies the QoS requirements, such as end-to-end delay, packet loss, and bandwidth, remains a difficult task in SDN. To overcome this limitation, a Deep Reinforcement Learning (DRL)-based Prioritized Experience Replay-based … …Journal of Computer Science, Vol. 22, Issue 8 · 4 Aug 2026 · 1,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractSmart and Secure Anomaly Detection in IoT Using Quantum Inspired Kernel Ensemble LearningAbrar M. AlajlanThe exponential growth of the Internet of Things networks has greatly increased the attack surface for cyber threats, necessitating the use of strong and perceptive anomaly detection systems. Traditional intrusion detection systems often struggle with high false alarm rates, limited generalization, and inefficiency in processing high-dimensional heterogeneous IoT data. To address this issue, a novel Hybrid Quantum-Enhanced Kernel Ensemble Learning … …Journal of Computer Science, Vol. 22, Issue 3 · 12 Mar 2026 · 1,769 accessesView PDFCite
Research ArticleOpen accessIn the abstractWhite Light Generation in Dy3+-Doped Sodium Lead Alumino Borosilicate Glasses for W-LED ApplicationsK. Vijaya Babu, A. Subba Rao, V. Madhuri, K. SureshExcitation and emission spectra of sodium lead alumino borosilicate glass doped with different concentrations of Dy3+ have been reported. The concentration of Dy3+ were varied from 0.5 to 1.5 mol%. As a result of 385 nm excitation wavelength, the luminescence spectra showed three characteristic bands at 482 nm and 575 nm and 665 nm. These absorption bands were attributed to … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 3 Jun 2020 · 6,861 accessesView PDFCite
