Research ArticleOpen accessIn the abstractLab-on-Chip Methodology in the Energy Industry: Wettability Patterns and Their Impact on Fluid Displacement in Oil Reservoir ModelsMarc H. Schneider, Patrick TabelingProblem statement: We present an experimental study of multiphase transport in porous media with controlled wettability patterns based on lab-on-chip methodology. Approach: Fractional, or patterned, wettability is known to have an enormous impact in the petroleum industry on oil recovery and continuous efforts are being made to assess the role of such conditions. Results: Thus far, due to the absence … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 7,885 accessesView PDFCite
Research ArticleOpen accessIn the abstractPredictor Factors of Telecentres Outcome from the Users Perspectives in Rural CommunitiesMohammad Badsar, Bahaman Abu Samah, Musa Abu Hassan et al.Problem statement: Information and Communication Technologies (ICTs) in developing countries is considered as a fundamental strategy of community development. In this regard, the government of Malaysia and developing agencies considered telecentres as a tool for providing the potential and benefits of ICTs for rural and remote community in order to make value and offer equal ICT access to all Malaysians … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 7,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Buddha Images and Conservation and Adherence to Cultural Values in NortheastAthikan Suksri, Souneth Phothisane, Sastra Laoakka et al.Problem statement: This study is caused by the problem of conservation of the Buddha images to exist in the original condition and by the problem of transference and adherence to indigenous knowledge of local craftsmen. At present there have not yet been systematic and wide conservation and adherence to the Buddha images. Other causes are such as incorrect techniques of … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Parallel Subunit for Synthesis Mathematical ModelsIssa M. ShehabatProblem statement: Mathematical modeling of different natural and technical objects and processes is one of the most important directions that needs high performance computing with huge memory. To reduce the computational time and expenses we need to carry out the calculations on specialized subunits. Approach: We described a self-organizing approximation method and introduced a new methodology of structural synthesis of … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractCarbon Dioxide Transfer with Chemical Equilibrium Reactions: An Alternative Mathematical ApproachA. ShanablehProblem statement: Despite intensive research efforts on CO2 transfer, mathematical models that describe the dependence of the CO2 transfer rate on the pH and the degree of rate enhancement due to CO2 chemical reactions remain unavailable. Approach: Such models are essential for assessing and accurately describing the progress of the CO2 transfer process. Results: In this study, an alternative view … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,046 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Use of Rolling Element Bearings' Models in Precision MaintenanceIoannis S. Zotos, Theodore N. CostopoulosProblem statement: Rolling element bearings form a very important part of machinery. The increasing demands on their continuous reliable operation under diverse environments make maintenance a very important step towards the efficient use of them. To this end, precision maintenance is a very useful practice, since it deals not only with finding a possible fault of a machine, but also … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of the Fracture Toughness of the Concrete Mortars Exposed to Elevated TemperaturesS. Djaknoun, A. Ahmed Benyahia, E. OuedraogoThe main objective of this research was the characterisation of the fracture toughness of concrete mortars exposed to high temperatures by using notched specimens in three point bending tests. The specimens have different lengths and were heated at different temperatures ranging from room temperature up to 900°C. The experimental test results obtained are closed with those reported by the literature, … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 6,527 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordShots Temporal Prediction Rules for High-Dimensional Data of Semantic Video RetrievalShaimaa Toriah Mohamed Toriah, Atef Zaki Ghalwash, Aliaa A.A. YoussifTemporal consistency stands as a vital property in semantic video retrieval. Few research studies can exploit this useful property. Most of the used methods in those studies depend on rules defined by experts and use ground-truth annotation. The Ground-truth annotation is time-consuming, labor intensive and domain specific. Additionally, it involves a limited number of annotated concepts and a limited number … …American Journal of Applied Sciences, Vol. 15, Issue 1 · 30 Jan 2018 · 8,120 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Some Fermentation Parameters on Ethanol Production from Beet Molasses by Saccharomyces cerevisiae CAIM13Awatif Abid Al-JudaibiProblem Statement: Some component of fermentation medium showed to reduce the Saccharomyces cerivisae production of ethanol. Approach: This study was designed to evaluate the role of some fermentation parameters in affecting ethanol productivity from beet molasses BM by Saccharomyces cerevisiae CAIM13. Results: Increase in cell concentration (inoculums size) of the yeast above 3.6×105 cells/100 mL decreased the ethanol yield. The … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 25 Jun 2011 · 8,924 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDNA Sequence Optimization Based on Continuous Particle Swarm Optimization for Reliable DNA Computing and DNA NanotechnologyN. K. Khalid, Z. Ibrahim, T. B. Kurniawan et al.Problem statement: In DNA based computation and DNA nanotechnology, the design of good DNA sequences has turned out to be an essential problem and one of the most practical and important research topics. Basically, the DNA sequence design problem is a multi-objective problem and it can be evaluated using four objective functions, namely, Hmeasure, similarity, continuity and hairpin.
