Research ArticleOpen accessIn the abstractA Unique Novel Approach for Design and Analysis of A Robust Decentralized Self-Tuning Fuzzy PI Controller for a Multi Input Multi Output ProcessP. Sujatha Therese, N. Kesavan NairProblem statement: In the real world most of the controlled processes in industries are Multi-Input Multi-Output (MIMO) in nature.They have more than a single controlled variable that should be manipulated in order to achieve the desired control performance. Approach: Control of non linear Multi Input Multi Output processes, it is a difficult task because of the non stationary behaviour, substantial … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 17 Jan 2012 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating Agility in Extended Enterprise Systems: A Transportation Network caseMo Mansouri, Anirban Ganguly, Ali MostashariProblem statement: Agility of an enterprise system is considered as its ability to adapt successfully and efficiently to unexpected changes of the environment. Agility is key in effectiveness of enterprise systems and also it is crucial in gaining competitive advantage in global market. Approach: This is particularly true in the case of an Extended Enterprise System (EES), which represents a … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 15 Mar 2011 · 8,751 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Scalable and Reliable Cost Effective Key Agreement Protocol for Secure Group CommunicationS. Jabeen Begum, Dr. T. PurusothamanProblem statement: In a heterogeneous environment, for a secure multicast communication, the group members have to share a secret key which is used to encrypt/decrypt the secret messages among the members. The Secure Group Communication of large scale multicast group in a dynamic environment is more complex than securing one-to-one communication due to the inherent scalability issue of group key … …Journal of Computer Science, Vol. 7, Issue 3 · 7 Mar 2011 · 6,960 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Auditory Based Interaction Framework for Driver Assistance SystemDalbir SinghProblem statement: The rapid development of Driver Assistance System (DAS) provides drivers with radically enhanced information and functionality. The nature of the current DAS requires a complex human-machine interaction which is distracting and may increase the risk of road accidents. The interaction between the driver and DAS should aid the driving process without interfering with safety and ease of vehicle … …Journal of Computer Science, Vol. 6, Issue 12 · 22 Nov 2010 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsymptotic Behavior of an Artificial Neural Network Defined on Multipartite Directed GraphN. C. Majee, A. B. RoyProblem statement: Artificial Neural Network (ANN) are simple models to mimic some essential features of the complex central nervous system. ANN models are realistic due to their inherent stochastic nature of neural computation and strong synchronicity. Different ANN models are associated with directed and signed graphs. The present study proceeded by relaxing certain simplifying assumptions in the ANN model. Approach: … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 7,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegration of Electrical and Electromagnetic Investigation for Contaminated SiteAlberto Godio, Mario NaldiProblem statement: The environmental assessment of industrial areas is required to minimize the risk of soil and groundwater contamination. The survey of wide areas (e.g., some hectares) provides a high economical and complex logistical impact when random strategies of soil sampling are adopted. Recently, geophysical methods had been successfully adopted to drive the process of the spatial sampling of the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn assessment of Urban Quality of Life by Using Analytic Hierarchy Process Approach (Case study: Comparative Study of Quality of Life in the North of Iran)Sedigheh Lotfi, Karim SolaimaniProblem Statement: Researches of quality of life are concentrated mainly on the urban nature in the recent years and the urban quality of life gained many attentions in empirical studies. The concept of urban quality of life is a multi-dimensional and complex issue. So, needless to say that this concept can be used in planning when there is an appropriate … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 8,637 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Case for Interdisciplinary Environmental Education and ResearchWill Focht, Charles I. AbramsonProblem statement: Interdisciplinary environmental education and research at American colleges and universities have been criticized for ambiguous focus, insufficient integration and lack of rigor. Part of the reason for a clearly articulated conceptualization of the field is the failure to reach a consensus among those in the environmental profession and academic community on an overarching paradigm of environmental education and … …American Journal of Environmental Sciences, Vol. 5, Issue 2 · 30 Apr 2009 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractClosed form Solution for Scheduling Arbitrarily Divisible Load Model in Data Grid Applications: Multiple SourcesMonir Abdullah, Mohamed Othman, Hamidah Ibrahim, Shamala SubramaniamScheduling an application in data grid was significantly complex and very challenging because of its heterogeneous in nature of the grid system. When the Divisible Load Theory (DLT) model had emerged as a powerful model for modeling data-intensive grid problem, Task Data Present (TDP) model was proposed based on it. This study presented a new Adaptive TDP (ATDP) for scheduling … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,433 accessesView PDFCite
Research ArticleOpen accessIn the abstractHost Plant Mediated Population Variations of Cotton Whitefly Bemisia tabaci Gennadius (Aleyrodidae: Homoptera) Characterized with Random DNA MarkersYasodha Perumal, Murugan Marimuthu, Abida Puthenpeedikal Salim, Balasubramanian PonnusamyProblem statement: Whitefly, Bemisia tabaci is an important sucking pest of field, horticultural and ornamental plants causing feeding injuries besides spreading disease by acting as a vector of Gemini viruses. The polyphagous nature of the pest makes it as a highly complex species. Approach: The influence of host plants utilized by the species on the population differences at molecular level … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,211 accessesView PDFCite
