Research ArticleOpen accessIn the abstractDetection of Commercial Fraud in Processed Meat Products Using Rapid TechniquesAli M. Ahmed, Takwa H. Ismail, Reham R. Abouelmaatti et al.Meat adulteration with different species has become a considerable problem worldwide. It means that meat products contain undeclared meat species; so, the meat ingredients are not consistent with the label. It has direct impact on public health, religious faith, fair-trades and food safety standers. This study focused on species adulteration detection in meat products by applying accurate, slandered and fast … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 2 · 4 Jun 2020 · 7,821 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUtility-based Scheduling Frameworks for Efficient Quality-of-Service Differentiation in a Mixture of Real-time and Non-real-time TrafficsOlalekan Bello, Hushairi Zen, AL-Khalid Othman, Khairuddin Abdul HamidThis paper proposes a utility-based scheduling framework for efficient differentiation of users’ Quality-of-Service (QoS) in a broadband wireless access system involving heterogeneous mixed traffic flows. The utility-based scheduling framework, called Maximum QoS Satisfaction (MQS), is based on three novel Radio Resource Allocation (RRA) techniques; delay-based scheduling policy for Real-Time (RT), minimum-rate-based scheduling policy for Non-Real-Time (NRT) and a throughput-based scheduling … …Journal of Computer Science, Vol. 11, Issue 7 · 19 Oct 2015 · 7,143 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparative Study of Scheduling Al-gorithms in Cloud Computing EnvironmentIsam Azawi MohialdeenAn essential requirement in cloud computing environment is scheduling the current jobs to be executed with the given constraints. The scheduler should order the jobs in a way where balance between improving the quality of services and at the same time maintaining the efficiency and fairness among the jobs. Thus, evaluating the performance of scheduling algorithms is crucial towards realizing … …Journal of Computer Science, Vol. 9, Issue 2 · 11 Apr 2013 · 7,212 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Fuzzy Logic Based Power Control for Wideband Code Division Multiple Access Wireless NetworksN. Mohan, T. RavichandranProblem statement: Resource management is one of the most important engineering issues in 3G systems where multiple traffic classes are supported each being characterized by its required Quality of Service (QoS) parameters. Call Admission Control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning. Efficient CAC is necessary for the QoS provisioning in … …Journal of Computer Science, Vol. 8, Issue 8 · 4 Aug 2012 · 6,760 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUnequally 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 · 7,255 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMPLS Based Architecture for Mobility and End-to-End QoS Support in Fourth Generation Mobile NetworksAlejandro Quintero, Eduardo Del FrutosProblem statement: Next-generation mobile networks are evolving towards network architectures relying entirely on IP. Approach: These networks had to be scalable in order to support future IP traffic, namely new multimedia services and real time applications, while providing an effective mobility management mechanism to cope with increasingly mobile users. In addition to global connectivity, next-generation mobile networks will have to … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,691 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign of a High-Performance IP Switching ArchitectureHattab Guesmi, Belgacem Bouallegue, Ridha Djemal, Rached TourkiIn this study we present the architecture for use in high-performance switching networks with support quality of service (QoS) guarantees. Quality of services guarantees in terms of delay, through-put and loss rate can be provided by using mechanism's support like scheduling and buffer management at switching architecture in packet switching networks. Our architecture is based on a new data structure … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,812 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPerformance Evaluation of Interference Mitigation Techniques in 4G Networks in Mobile EnvironmentsEmna Hajlaoui, Abdelhakim Khlifi, Samia Dardouri et al.Intercell Interference (ICI) is one of the major factors that limit the performance and Quality of Service (QoS) of 4G wireless networks (Long Term Evolution/LTE-Advanced). For this reason, heterogeneous networks present an attractive solution for the improvement of mobile network’s services to provide better data rates and coverage. So, a key scheme in 4G traffic processing is the interference mitigation … …Journal of Computer Science, Vol. 15, Issue 12 · 25 Dec 2019 · 7,332 accessesView PDF Cite

Case ReportOpen accessIn the abstractChromomycosis: Case Reports of Exuberant Forms Including Carcinomatous DegenerationCarla Andréa Avelar Pires, Aline de Lima Dias, Adriana Kamilly Leitão Pitman Machado et al.Chromomycosis, or chromomycosis, is a chronic, progressive cutaneous and subcutaneous mycosis caused by several species of pheoid or dermaticeous (darkly pigmented) fungi. It mainly affects male patients, in the age group between 30 and 60 years and is more common on rural areas, being associated to traumatic events, which may explain the high frequency of involvement of the lower limbs … …American Journal of Infectious Diseases, Vol. 15, Issue 1 · 6 Feb 2019 · 7,765 accessesView PDF Cite

Research ArticleOpen accessIn the abstractHorizontal Cooperation Practices in Internet-based Higher Education, Computational Logistics and TelecommunicationsJesica de Arma, Thanasis Daradoumis, Anastasios A. Economides, Angel A. JuanGlobalization and advances in information and communication technologies have boosted the use of Horizontal Cooperation (HC) practices in many industry sectors. In the current international market, these ‘alliances’ become especially relevant for small and medium organizations, which are forced to compete with large-scale corporations. This paper analyzes benefits and challenges of HC practices in three service sectors that are critical … …Journal of Computer Science, Vol. 15, Issue 1 · 31 Jan 2019 · 7,428 accessesView PDF Cite
