Research ArticleOpen accessIn the abstractImproving the Gas Instantaneous Water Heaters PerformancesNasir KloubThis study presents a study of a theoretical and practical investigation of the gas Instantaneous (Tankless) water Heaters performance. The results allow us to obtain realistic values of the control system in the various capacities gaseous flowing water heaters. The objective of this work is to study the operation of the plans in the field of controlling and checking low … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,511 accessesView PDFCite
Research ArticleOpen accessIn the abstractMorphing Mechanisms Part 2: Using Repetitive Control to Morph Cam Follower MotionNonglak Phetkong, Meng-Sang Chew, Richard W. LongmanThis research utilizes the repetitive control approach in morphing a high-speed cam mechanism so that its output displacement tracks the desired output trajectory. The main objective is to reduce the output tracking error, which is the difference between the actual and desired output displacements of the output mass. A 3-degree of freedom mathematical model is used to analyze and represent … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,369 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarthquake Airbags, New Devices to Save Lives in Earthquakes, Tornados and Similar Disasters Resulting from Building CrashesAmir Hashem Shahidi BonjarEarthquake Airbag (EA) is a new terminology being introduced for the earthquake literature of the world. According to literature surveys, this terminology has not been used previously. Based on many scientific reports, fatality rates are lower in vehicles equipped with airbags than unequipped ones. Accordingly, it was postulated that similar structures can be adopted in buildings to protect people and … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,528 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtension to Sufficient Optimality Conditions in Complex ProgrammingE. A. Youness, M. E. ElbrolosyIn this study we extend the sufficient optimality conditions of complex programming problems to a large class of functions that include the two parts (real and imaginary) of the objective function. The sufficient conditions were established under generalized forms of convexity assumptions. The previous results that considered the real part only can be deduced as special cases. …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,242 accessesView PDFCite
Research ArticleOpen accessIn the abstractSeek of an Optimal Way by Q-LearningY. Dahmani, A. BenyettouIn this article, we presented the Q-Learning training method which is a derivative of the reinforcement learning called sometimes training by penalty-reward. We illustrate this by an application to the mobility of a mobile in an enclosure closed on the basis of a starting point towards an unspecified arrival point. The objective is to find an optimal way optimal without … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,929 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation into the Use of the Least Significant Bit Substitution Technique in Digital WatermarkingKevin Curran, Xuelong Xi, Roisin ClarkeDigital imaging companies lose revenue each year to people who are illegally copying and using their images. One prevention mechanism is to digitally encode images making it difficult for others to copy. This could be done using digital fingerprinting or simply adding a visible watermark. The information is hidden in a way that should not attract attention, but make it … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,469 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Situation and Evaluation of Forest Harvesting Methods in TurkeyMurat Demir, Tolga OzturkThe present study summarize and evaluate major problems of timber harvesting in Turkey and the future principles and objectives have been defined. Timber harvesting in Turkey is still carried out by manual methods due to economical, social and environmental constraints. Almost 80% of harvesting activities are mechanized in many developed countries while this value is only 5% in Turkey. Overall … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of Wastewater Oxidation under Microgravity ConditionsBoyun Guo, Donald W. Holder, David S. SchechterVolatile removal assembly (VRA) is a module installed in the International Space Station for removing contaminants (volatile organics) in the wastewater produced by the crew. The VRA contains a slim pack bed reactor to perform catalyst oxidation of the wastewater at elevated pressure and temperature under microgravity conditions. Optimal design of the reactor requires a thorough understanding about how the … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Voltage Stability and Alleviation Through Knowledge Based SystemA. Arunagiri, B. VenkateshModern power systems are large sized and rapidly growing. They require constant attention to monitor their performance. Attention is also required to ensure that the voltage stability margin of the power system is above a desired level. In order to achieve the objective, this study proposes a knowledge-based system. It computes using simple Fast De-Coupled Load Flow (FDLF), the state … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 6,816 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Characterization of Banana (AA) Diploids with Contrasting Levels of Black and Yellow Sigatoka ResistanceClaudia Fortes Ferreira, Sebastiao Oliveira Silva, Nivia Paula Damasceno Sobrinho et al.Most banana cultivars are susceptible to many diseases, whereas Sigatoka leads to greatest yield losses. One of the strategies to overcome this disease is thorough banana genetic breeding which consists in the obtainment of improved (AA) diploids which are then crossed with triploids obtaining (AAAB) tetraploid disease resistant bananas also presenting other important agronomic characteristics. The prior knowledge of the … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,652 accessesView PDFCite
