Research ArticleOpen accessEvery word in the titleGrid Voltage Stability Enhancement Using Photovoltaic Based Static Synchronous CompensatorSubhransu Sekhar Dash, Arun Bhaskar Mayilvaganan, Venkatesh VenkataramananToday, we are mostly dependent on non renewable energy that have been and will continue to be a major cause of pollution and other environmental degradation. Because of these problems and our dwindling supply of petroleum, finding sustainable alternatives is becoming increasingly urgent. Perhaps, the greatest challenge is in devising a sustainable future, which relies on integration and control of … …Journal of Computer Science, Vol. 9, Issue 3 · 17 Apr 2013 · 6,861 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancement of Biogas Production Potential for Anaerobic Co-digestion of Wastewater using Decanter CakeThaniya Kaosol, Narumol SohgrathokThe wastewater from agro-industry treated with the biological treatment cannot produce the biogas because of its low COD level and its low organic content. In this research, the co-digestion with decanter cake will improve the biogas yield and biogas production of wastewater. The effect of three parameters (i.e., type of wastewater, mixing and mesophilic temperature) will be evaluated in batch … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 15 Mar 2013 · 7,717 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancement of Quality of Service Parameters in Wimax Mobile NetworksChandra, HelenPrabhaNext generation mobile networks are expected to provide seamless personal mobile communication and QoS. Since the demands for high speed Internet access as well as multimedia service had increased for last mile broadband access, the Scheduling is one of the most important components of BWA systems that affect system QoS provided to users. Priority queuing gives better throughput than the … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 7 Nov 2012 · 6,833 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Application of Interpersonal Relationship Poll to the Enhancement of Management EfficacyKuo-Wei Lin, Wen-Chi KuProblem statement: Every employee needs to directly face their different superiors and subordinates that he must have ability to get along with other people or teams. It is the ability that he could communicate, coordinate, convince, negotiate and inspire his working partners smoothly and the organization, leadership and control could be implemented in accordance with the established plans. So the … …Journal of Social Sciences, Vol. 8, Issue 3 · 16 Jul 2012 · 7,636 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnhancement of Voltage Stability by Optimal Location of Static Var Compensator Using Genetic Algorithm and Particle Swarm OptimizationR. Kalaivani, V. KamarajProblem statement: Voltage instability and voltage collapse have been considered as a major threat to present power system networks due to their stressed operation. It is very important to do the power system analysis with respect to voltage stability. Approach: Flexible AC Transmission System (FACTS) is an alternating current transmission system incorporating power electronic-based and other static controllers to enhance … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 11 May 2012 · 9,443 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDigital Simulation, Design, Comparitive Analysis of Intelligent Controllers in Adjustable Speed Drives for PQ EnhancementA. Srikrishnan, B. Justus RabiProblem statement: This study deals with the analysis, design and comparison between fuzzy and genetic based adjustable speed drives with respect to the parameters which determines the quality of power. Approach: ASD system using fuzzy controllers provide ride-through capability during voltage sags, reduces harmonics, improves power factor and is highly reliable, whereas by using genetic algorithm optimized ASD systems, the … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 21 Nov 2011 · 7,012 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Enhancement Technique of the Hill Cipher for Effective Cryptographic PurposesA. F.A. Abidin, O. Y. Chuan, M. R.K. AriffinProblem statement: The Hill cipher is the first polygraph cipher which has a few advantages in data encryption. However, it is vulnerable to known plaintext attack. Besides, an invertible key matrix is needed for decryption. It may become problematic since an invertible key matrix does not always exist. Approach: In this study, a robust Hill algorithm (Hill++) has been proposed. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 8,545 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Enhancement of Bayesian Inference Network for Ligand-Based Virtual Screening using Features SelectionAli Ahmed, Ammar Abdo, Naomie SalimProblem statement: Similarity based Virtual Screening (VS) deals with a large amount of data containing irrelevant and/or redundant fragments or features. Recent use of Bayesian network as an alternative for existing tools for similarity based VS has received noticeable attention of the researchers in the field of chemoinformatics. Approach: To this end, different models of Bayesian network have been developed. … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,721 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBasic and Reactive Dyes Sorption Enhancement of Rice Hull through Chemical ModificationSiew-Teng Ong, Pei-Sin Keng, Chnoong-Kheng LeeProblem statement: Many studies have been conducted on the removal of either anionic or cationic dyes. However, as a mixture of dyes does commonly exist together in wastewater, therefore it is of great interest to have a material that can remove both types of dyes. Approach: To prepare an inexpensive and efficient sorbent by chemically modifying rice hull for the … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,787 accessesView PDFCite
