Research ArticleOpen accessAll words, across the recordAn Analysis of Urban Land Development Using Multi-Criteria Decision Model and Geographical Information System (A Case Study of Babolsar City)Sedigheh Lotfi, Kiomarth Habibi, Mohammad Javad KoohsariProblem Statement: The unplanned physical expansion of cities has been one of the most important problems of urban management in developing countries. Iran, like other developing world has experienced a high level of urbanization growth which transformed the physical fabric of urban areas. North of Iran is one of most rapid growing region of the country where the moderate climate … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 8,708 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBeta-2-Microglobulin in Autism Spectrum DisordersPaula Goines, Joseph Schauer, Luke Heuer et al.Autism spectrum disorders (ASD) are heterogeneous neurodevelopmental diseases of unknown etiology. There are no biological markers for ASD and current diagnosis is based on behavioral criteria. Recent data has shown that MHC I, a compound involved in adaptive immune function, is also involved in neurodevelopment, synaptic plasticity and behavior. It has been suggested that altered MHC I expression could play … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,560 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAdaptive Control of Robotic Manipulators with Improvement of the Transient Behavior Through an Intelligent Supervision of the Free-Design Parameters and the Sampling PeriodM. De La Sen, A. Almansa, J.C. SotoAn adaptive control scheme for mechanical manipulators proposed. The control loop consists of a network for learning the robot's inverse dynamics and on-line generating the control signal. Some simulation results were provided to evaluate the design. A supervisor was used to improve the performances of the system during the adaptation transients. The supervisor exerts two supervisory actions. The first one … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,881 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Hybrid Model for Load Aware Trust Management in GridK. Selvi, R. S.D. Wahida BanuProblem statement: Trust management in a distributed dynamic environment like grid has been very vital since the allocation of appropriate resources to meet user request influences the success of the system. While considering a set of resources which are loaded invariably, balancing the load also contributes for the efficient resource utilization. Approach: This study proposes a trust calculation model, which … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 6,531 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEvolutionary Algorithm DefinitionNada M.A. AL-SalamiProblem statement: Most resent evolutionary algorithms work under weak theoretical basis and thus, they are computationally expensive. Approach: This study discussed the use of new evolutionary algorithm for automatic programming, based on theoretical definitions of program behaviors. Evolutionary process adapted fixed and self-organized input-output specification of the problem, to evolve good finite state machine that efficiently satisfies these specifications. Results: … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 10 Dec 2009 · 7,751 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEnvironmental Factors and Limbic Vulnerability in Childhood AutismRichard LatheThe rise in prevalence of autism spectrum disorders (ASD) is suggestive of a new etiology. Diagnostic substitution alone is unlikely to account for the increase, while genetic association with detoxification gene alleles points to an environmental contribution. Subtle structural anomalies in the ASD brain are widespread but limbic damage seems important for the development of behaviors diagnostic of ASD. The … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 2 · 30 Jun 2008 · 7,678 accessesView PDF Cite
