Research ArticleOpen accessIn the abstractModel Refinement in the Model Driven Architecture ContextInali Wisniewski Soares, Luciane Telinski Wiedermann Agner, Paulo Cezar Stadzisz, Jean Marcelo SimaoProblem statement: Model Driven Architecture (MDA) is a software development approach based on the design and the transformation of models. In MDA, models are systematically translated to other models and to a source code. Model transformation plays a key role in MDA. Several model transformation languages have been launched lately, aiming to facilitate the translation of input models to output … …Journal of Computer Science, Vol. 8, Issue 8 · 10 Jul 2012 · 7,195 accessesView PDFCite

Research ArticleOpen accessIn the abstractApplication of CART Algorithm in Blood Donors ClassificationT. Santhanam, Shyam SundaramProblem statement: This study used data mining modeling techniques to examine the blood donor classification. The availability of blood in blood banks is a critical and important aspect in a healthcare system. Blood banks (in the developing countries context) are typically based on a healthy person voluntarily donating blood and is used for transfusions or made into medications. The ability … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 8,624 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Methylene Blue from Aqueous Solution onto a Low-Cost Natural Jordanian TripoliAtef S. ALzaydienProblem statement: It is well documented that lead is one of contaminants of industrial wastewaters and its pollution exists in the wastewater of many industries.

Al-Shami, M.N. Siti Azizah, Che Salmah Md Rawi, Abu Hassan AhmadProblem statement: Chironomidae have been recorded in rice fields throughout the world including in many countries such as India, Australia and the USA. Although some studies provide the key to genera level and note the difficulty of identifying the larvae to species level. Chironomid researches have been hindered because of difficulties in specimen preparation, identification, morphology and literature. Systematics, phylogenetics … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,520 accessesView PDFCite
