Research ArticleOpen accessIn the abstractAssessment of Genetic Diversity among Sugarcane Cultivars (Saccharum officinarum L.) using Simple Sequence Repeats MarkersAshutosh Pandey, Rupesh K. Mishra, Shashank Mishra et al.Problem statement: Increasing sugar productivity is the main concern of sugarcane (Saccharum officinarum L.) breeding programs. The complexity and size of the sugarcane genome is a major limitation in its genetic improvement. Characterization of sugarcane provides essential information of genetic diversity for breeders utilize for crop improvement. Approach and Results: The objective of this study was to evaluate the microsatellite … …OnLine Journal of Biological Sciences, Vol. 11, Issue 4 · 27 Jan 2012 · 7,567 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDigital 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 · 7,019 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGenetic Polymorphisms in the Fat Mass and Obesity-Associated Gene Confers Risk of Obesity in Iraqi PopulationShatha Ramadhanzaidan, Faris Abd Al Kareem, Lujain Anwar AlkhazrajyProblem statement: Obesity is strongly influenced by genetic factors, with an estimated heritability of 60% BMI. Genetic susceptibility to the common form of obesity appears to be polygenic. Although theoretical analyses emphasized the power of genetic association study in common polygenic diseases, the search for genes conferring the risk of obesity has thus far not been very successful. Approach: In … …American Journal of Infectious Diseases, Vol. 7, Issue 2 · 21 Sep 2011 · 7,624 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Genetic Algorithm for Scheduling n Jobs on a Single Machine with a Stochastic Controllable Processing, Tooling Cost and Earliness-Tardiness PenaltiesMohamed Ali Abdel-Fattah MansourProblem statement: In this research, we addressed the problem of minimizing the earliness-tardiness penalties and manufacturing costs of a single machine with a stochastic controllable processing and tooling cost. Approach: We developed a mathematical non-linear integer programming model and its linearised version to find the optimal solution. We introduced a new genome representation in single machine scheduling literature that evolved … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 7,591 accessesView PDF Cite
