Research ArticleOpen accessIn the keywordsOptimal Control Algorithms for Second Order SystemsDanilo Pelusi, Raffaele MascellaProportional Integral Derivative (PID) controllers are widely used in industrial processes for their simplicity and robustness. The main application problems are the tuning of PID parameters to obtain good settling time, rise time and overshoot. The challenge is to improve the timing parameters to achieve optimal control performances. Remarkable findings are obtained through the use of Artificial Intelligence techniques as … …Journal of Computer Science, Vol. 9, Issue 2 · 2 Apr 2013 · 7,029 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSuppression of Salicylic Acid-Mediated Plant Defense Responses During Initial Infection of Dyer's Woad by Puccinia thlaspeosBradley R. Kropp, Elizabeth ThomasProblem statement: Puccinia thlaspeos is a microcyclic rust pathogen that is being investigated as a potential biocontrol agent of the noxious weed, dyer’s woad (Isatis tinctoria). Although, the initial events in the colonization of dyer’s woad by the rust pathogen has been elucidated using scanning electron microscopy and PCR, little is known regarding the susceptibility response of this plant to … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 8,033 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBiocontrol of Soil Fungi in Tomato with Microencapsulates Containing Bacillus subtilisMarcela Hernàndez-Suàrez, Francisco Daniel Hernàndez-Castillo, Gabriel Gallegos-Morales et al.Problem Statement: An option to reduce pollution by synthetic agro-chemical in root plant disease management is the use of antagonist rhizobacteria belonging to Bacillus genus, because their inhibitory properties, stimulation of plant growth and crop yield increase. Approach: This study was carried out in order to evaluate if Bacillus subtilis strains could play an antagonists role of plant pathogens and … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,925 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Drought Stress and Methanol on Yield and Yield Components of Soybean Max (L 17)Mojtaba Mirakhori, Farzad Paknejad, Foad Moradi et al.Problem statement: In order to evaluate drought stress and methanol on yield and yield components of soybean in field experiments with factorial experiment inform of a randomized complete block design with three replication in field faculty of agricultural of Islamic Azad University Karaj, at 2008. First factor were sprayed aqueous solutions 0 (control), 7, 14.21, 28 and 35% (v/v) methanol … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 7,881 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhysiological Response of Soybean (Glycine max) to Foliar Application of Methanol Under Different Soil MoisturesFarzad Paknejad, Mojtaba Mirakhori, Majid Jami Al-Ahmadi et al.Problem statement: Many cultivated area are situated in arid zone, where crop photosynthesis and productivity has limited by drought. Thus any treatment, such as methanol, that improve plant water relation and reduce stress impacts, could be benefit. Approach: In order to investigate effects of methanol application on some physiological properties of soybean under low water stress, a factorial experiment was … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,150 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison of Stochastic and Deterministic Methods for Mapping Environmental Noise from Opencast QuarriesDario Lippiello, Guido Alfaro Degan, Mario PinzariAn accurate mapping of the acoustic spatial variability generated by quarrying plants constitutes an important step in the assessment of the environmental compatibility of the extraction site with the surrounding area. This paper refers to the results of a study comparing performances obtained by stochastic and deterministic methods to determine the acoustic climate of the areas surrounding opencast quarries. To … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 28 Mar 2016 · 7,394 accessesView PDF Cite
