Research ArticleOpen accessIn the abstractDevelopment of New Didactic Materials for Teaching Science and Biology: The Importance of the New Education PracticesDanon Clemes Cardoso, Maykon Passos Cristiano, Camila Orlandi ArentProblem statement: The creativity of teachers in the planning process of their classes for teaching science and biology may be an instigator to promote and stimulate learning. The science should be something that awakens curiosity in students to make learning pleasurable and increase their interest. The aim this research was to develop didactic materials for to help the teaching-learning process … …OnLine Journal of Biological Sciences, Vol. 9, Issue 1 · 31 Mar 2009 · 8,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn New Bijective Convolution Operator Acting for Analytic FunctionsOqlah Al-Refai, Maslina DarusProblem statement: We introduced a new bijective convolution linear operator defined on the class of normalized analytic functions. This operator was motivated by many researchers namely Srivastava, Owa, Ruscheweyh and many others. The operator was essential to obtain new classes of analytic functions. Approach: Simple technique of Ruscheweyh was used in our preliminary approach to create new bijective convolution linear … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 8,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation Planning for Sustainable Use of Land Resources: Case study in DiamouDiallo Yacouba, Hu Guangdao, Abdurazak Hussien AbdulahiIn this study, we presented the simulation planning scheme to project land and land resources use changes at a local scale for Diamou (MALI). Problem statement: All the land cover types were under the influence of human and livestock population. Diamou has undergone changes in land-cover over the last decades. The shifting cultivation system practiced was probably the main reason … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractHepatitis B Diagnosis Using Logical Inference and Self-Organizing MapGhumbre Shashikant Uttreshwar, A.A. GhatolDespite all the standardization efforts made, medical diagnosis is still regarded as an art owing to the fact that that medical diagnosis requires an expertise in handling the uncertainty which is unavailable in today's computing machinery. Though artificial intelligence is not a new concept it has been widely recognized as a new technology in computer science. Numerous areas such as … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 6,878 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Complete Automation of Unit Testing for JavaScript ProgramsM. AlshraidehProblem statement: Program testing is expensive and labor intensive, often consuming more than half of the total development costs, and yet it is frequently not done well and the results are not always satisfactory. The objective of this paper is to present an automatic test data generation tool that aims to completely automate unit testing of JavaScript functions. The methodology: … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractTaxonomic Significance of ISTR to Discriminate Species in AgavaceaeMartha Isabel Torres-Morán, Norma Almaraz-Abarca, Ana Paulina Velasco-Ramírez et al.Family Agavaceae is endemic of American Continent. From the around 300 species recognized in this family, 217 occur in Mexico. Relevant ethnobotanic relationships among Agavaceae and the several native human cultures of the American Continent have been established since prehispanic times. Agave is one of the most important genus in that family due to its great diversity and abundance, mainly … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,195 accessesView PDFCite
Research ArticleOpen accessIn the abstractReed-Muller Codec Simulation PerformanceO. O. Khalifa, A. H. Abdullah, N. Suriyana et al.The approach to error correction coding taken by modern digital communication systems started in the late 1940's with the ground breaking work of Shannon, Hamming and Golay. Reed-Muller (RM) codes were an important step beyond the Hamming and Golay codes because they allowed more flexibility in the size of the code word and the number of correctable errors per code … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 7,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Sulfur Dioxide (SO2) Concentration Levels from the Mina Al-Fahal Refinery in Oman Using Artificial Neural NetworksSabah A. Abdul-Wahab, Saleh M. Al-AlawiIn this investigation, two Artificial Neural Network (ANN) models were applied for predicting ground-level sulfur dioxide (SO2) in the Sultanate of Oman in order to provide an early warning advisory for the protection of public health. The objective of the first model (Model I) was to use ANN to predict sulfur dioxide (SO2) levels at certain receptors from the Mina … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing the Spreadsheet to Understand Random Sampling Procedures in Relation to the Central Limit TheoremRamzi Naim NasserIn many statistics courses in colleges and universities, random sampling has not been presented to students through a hands-on and practical approach. This research described a real-life method to random sampling was used as an exercise in the statistics class. The method allowed students to recursively select 5, 10, 20, 30, 40, 50, 60 and 70 samples and list these … …Journal of Mathematics and Statistics, Vol. 4, Issue 3 · 30 Sep 2008 · 6,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeighting Spatial Information in GIS for Copper Mining ExplorationFarhad Hosseinali, Ali Asghar AlesheikhExploration of new mines is vitally important for human life. Geospatial Information Systems (GIS) can be effectively used in the gathering, weighting, analyzing and presenting spatial and attribute information to facilitate the mine exploration process. The success of mine exploration largely depends on: the identification of governing factors, the determination of their impacts and the selection of suitable models to … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 8,609 accessesView PDFCite
