Research ArticleOpen accessIn the abstractSugarcane Response to Water-Deficit Stress during Early Growth on Organic and Sand SoilsDuli Zhao, Barry Glaz, Jack C. ComstockProblem statement: Approximately 20% of sugarcane (Saccharum spp.) is grown on sand soils in south Florida, USA. Sugarcane yields in the region linearly increased in last 33 years on organic (muck) soils, but not on sand soils. Water deficit during the formative growth phase on sand soils probably limits sugarcane yields. Approach: A greenhouse study was conducted in 2009 and … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 10,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractControl of a Step Walking Combined to Arms Swinging for a Three Dimensional Humanoid PrototypeAmira Aloulou, Olfa BoubakerProblem statement: Present researches focus to make humanoid robots more and more autonomous so they can assist human in daily works like taking care of children, aged or disabled persons. In such social activities, the contemporary humanoid robots are expected to have human like morphology and gait. Studies on bipedal locomotion for humanoid robots are then part of the hottest … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,423 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Neural Network Based Model for Forecasting Sugar Cane ProductionO. O. Obe, D. K. ShangodoyinProblem statement: The global need for alternative energy source has necessitated the exploration of vast organic agricultural products with a view of processing them for the production of ethanol in commercial quantity. To ascertain a sustainable production of ethanol from processed sugar cane, a predictive model based on non-linearity nature of its production is imperative. This is due to unavailability … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 7,272 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn-Cylinder Heat Transfer Characteristics of Hydrogen Fueled Engine: A Steady State ApproachM. M. Rahman, Khalaf I. Hamada, M. M. Noor et al.This study presents in-cylinder heat transfer characteristics of a single cylinder port injection Hydrogen fueled Internal Combustion Engine (H2ICE) using a steady state approach. Problem statement: The differences in characteristics between hydrogen and hydrocarbon fuels are led to the difference in the behavior of physical processes during engine cycle. One of these processes is the in-cylinder heat transfer. Approach: One … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacteristics of Compound Multiplicity in 24Mg with Emulsion at 4.5 A GeV/cA. Abd El-DaiemProblem statement: The interactions of 24Mg at 4.5A GeV/c with an emulsion can reveal some compound multiplicity characteristics. Approach: Furthermore, the number of grey and shower particles taken together a termed the compound multiplicity. Results: The results revealed that the compound multiplicity distributions become wider with increasing the size of the struck nucleus and the value of the <nc> increases … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 7,510 accessesView PDFCite
Research ArticleOpen accessIn the abstractPiecewise Sliding Mode Decoupling Fault Tolerant Control SystemRafi Youssef, Hui PengProblem statement: Proposed method in the present study could deal with fault tolerant control system by using the so called decentralized control theory with decoupling fashion sliding mode control, dealing with subsystems instead of whole system and to the knowledge of the author there is no known computational algorithm for decentralized case, Approach: In this study we present a decoupling … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractOmega Network Hash ConstructionChai Wen Chuah, Azman SamsudinProblem statement: Cryptographic hash functions are important cryptographic primitives. They are commonly used for data integrity checking and data authentication. Most of the cryptographic hash functions are based on the Merkle-Damgård construction. The basic Merkle-Damgård construction runs over the input sequentially, which can lead to problems when the input size is large since the computation time increases linearly. Approach: Therefore, … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,127 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dual-Slope Integration Based Analog-to-Digital ConvertorHasan KradProblem statement: With the advent of the advanced technology and the need for more advanced equipment, the current progress and development of electronic instruments stimulate more interest and efforts for more innovative ideas and better designs. Many real world physical values, such as sounds, temperature, pressure and humidity, can be measured as analog or continuous signals. However, to process these … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling of the Three Phase Induction Motor Couple to DC Motor in Hybrid Electric VehicleZulkarnain Lubis, A. N. Abdalla, Mortaza, Ruzlaini GhonProblem statement: With emphasis on a cleaner environment and efficient operation, vehicles today rely more and more heavily on electrical power generation for success. Approach: Mathematical modeling the components of the HEV as the three phase induction motor couple to DC motor in hybrid electric vehicle was introduced.

Research ArticleOpen accessIn the abstractA New Engineering Method for Fuzzy Reliability Analysis of Surge Control in Centrifugal CompressorAhmed Hafaifa, Ferhat Laaouad, Moulod GuemanaProblem statement: The surge phenomenon in the centrifugal compressor, the non-linearities and uncertainties of the compression system make it impossible to use a conventional controller over a wide range of operation. Approach: A new dual fuzzy controller for nonlinear model of compression system was proposed in this study. This fuzzy controller was designed that consisted of active surge control and … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 8,229 accessesView PDFCite
