Research ArticleOpen accessIn the abstractDESIGN AND DEVELOPMENT OF A RECOMMENDER SYSTEM FOR E-LEARNING MODULESBaseera, SrinathExtensive literature review revealed that, different recommender systems for E-learning were developed. A preliminary version of the development was undertaken and evaluated in an experiment during an introduction psychology course in an open university. The activities were integrated in to a model which operates on a network. No curriculum structure was assigned and the users were allowed to undergo learning … …Journal of Computer Science, Vol. 10, Issue 5 · 26 Dec 2013 · 7,097 accessesView PDFCite
Research ArticleOpen accessIn the abstractDISTRIBUTIVE POWER MIGRATION AND MANAGEMENT ALGORITHM FOR CLOUD ENVIRONMENTP. Prakash, G. Kousalya, Shriram K. Vasudevan, Kawshik K. RangarajuIn cloud computing, the resources are provided as service over the internet on demand basis. The resources such as servers, networks, storage, applications are dynamically scaled and virtualized. The demand grows gradually for each virtual machine in a cloud computing environment over time. So, it is necessary to manage the resources under each cluster to match the demand in order … …Journal of Computer Science, Vol. 10, Issue 3 · 29 Nov 2013 · 6,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractENERGY EFFICIENT AND INTERFERENCE AWARE PROVISIONING IN VIRTUALIZED SERVER CLUSTER ENVIRONMENTMohan Raj Velayudhan Kumar, Shriram RaghunathanIT service providers, employ server virtualization as a main building block to improve system utilization, improve system manageability, reduce operational costs which includes energy consumption driving economies of scale with shared resources. Virtualization enables co-locating and efficient assignments of virtual servers within the bounds of limited number of heterogeneous physical servers, with Virtual Machines (VM) sharing the limited physical server … …Journal of Computer Science, Vol. 10, Issue 1 · 12 Nov 2013 · 6,692 accessesView PDFCite
Research ArticleOpen accessIn the abstractLabview Based Autonomous Agricultural Robot Using Fuzzy Logic ControllerPrema Kannan, Senthil Kumar Natarajan, Subhransu Sekar DashThis study proposes a LabVIEW based autonomous agricultural robot which can be used for ploughing. The control logic is designed using fuzzy logic controller to operate the robot in autonomous mode. The robot can also be controlled from a remote place using internet and its position is monitored using Global Positioning System (GPS), Data Socket protocol and Wi-Fi connection. Two … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 24 Sep 2013 · 7,048 accessesView PDFCite
Research ArticleOpen accessIn the abstractResource Selection in Grid Environment Based on Trust Evaluation Using Feedback and PerformancePrakash Mohan, Ravichandran ThangavelA grid computing is a collection of distributed computing resources owned by many organizations across boundaries and not dedicated for a single user available in the Virtual Organization. Grid computing environment provides more computational capabilities to increase the scalability and efficiency of the infra-structure. Resource selection in computational grid is the open issue for executing complex jobs. Trust is the … …American Journal of Applied Sciences, Vol. 10, Issue 8 · 24 Jul 2013 · 7,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractDESIGN OF FUZZY LOGIC CONTROLLER FOR ONLINE SPEED REGULATION OF DC MOTOR USING PWM TECHNIQUE BASED ON LABORATORY VIRTUAL INSTRUMENT ENGINEERING WORKBENCHPrema Kannan, Senthil Kumar Natarajan, Subhransu Sekar DashThis study details online speed regulation of DC motor using PWM technique based on LabVIEW. A fuzzy logic controller is designed to change the pulse width of switching signal applied to the converter and thereby the voltage fed to the armature of the separately excited DC motor to regulate the speed. The proposed system is connected to the server computer … …Journal of Computer Science, Vol. 9, Issue 8 · 4 Jul 2013 · 6,715 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware in the Loop Simulator for Multi Agent Unmanned Aerial Vehicles EnvironmentKamal S. Ali, Justin L. ShumakerThis study describes a Multi-Agent Hardware In the Loop Simulator (HILS) for Unmanned Aerial Vehicles’ (UAV) autopilots. This HILS system allows multiple autopilots to fly multiple virtual airframes in the same virtual environment allowing these agents to interact as a swarm. This system makes the exploration and evaluation of Multi Agent Systems (MAS) possible at minimal cost. …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 10 May 2013 · 7,529 accessesView PDFCite
Research ArticleOpen accessIn the abstractIs Color Perception of Packages Affected by Their In-aisle Position?Daniele Porcheddu, Maura Pugliatti, Antonio PinnaThe retail environment is characterized by numerous competing stimuli vying for the consumer’s attention. Products packages feature both verbal and nonverbal elements. Nonverbal stimuli, like package colors, seem to be particularly relevant for perception. Knowing whether there is preferential positioning of colored items on the shelves is fundamental for retailers. In addition, some colors may be better perceived than others. … …American Journal of Economics and Business Administration, Vol. 4, Issue 2 · 20 Apr 2012 · 8,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Rejection Ratio in Cost Optimized Virtual Private Networks Provisioning Algorithm (COVPA) Using Waxman and Barabasi Model in Cyber SpaceRamanathan Rajasekar, Ramaraj Ravi, Beulah ShekharProblem statement: Virtual private networks have provided customers with a secure and low-cost communication environment. Approach: The COVPA, the provisioning algorithm for a Virtual Private Network service, which built and managed VPNs on demand. Results: The COVPA allowed each VPN to have guaranteed resources and customized control and supported a highly dynamic VPN service where creation and modification operations took … …Journal of Computer Science, Vol. 8, Issue 2 · 28 Nov 2011 · 7,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractReal-Time Volume Shadow using Visible-Non Visible AlgorithmHoshang Kolivand, Mohd Shahrizal Sunar, Azam Amirshakarami, Zhila RanjbariProblem statement: Shadows are most important effect to make realistic games and visually appealing images, but they are poor in frame per second. Silhouette detection is most important phases to create real-time shadow. Approach: Present study describes a real-time shadow generated with volume shadow algorithm using Visible-Non Visible algorithm (VNV) in virtual environment illuminated by a movable light source to … …Journal of Computer Science, Vol. 7, Issue 7 · 28 Jun 2011 · 6,988 accessesView PDFCite
