Research ArticleOpen accessIn the abstractEnhanced Ensemble Prediction Algorithms for Detecting Faulty Modules in Object Oriented Systems Using Quality MetricsM. Punithavalli, C. NeelamegamThe high usage of software system poses high quality demand from users, which results in increased software complexity. To address these complexities, software quality engineering methods should be updated accordingly and enhance their quality assuring methods. Fault prediction, a sub-task of SQE, is designed to solve this issue and provide a strategy to identify faulty parts of a program, so … …Journal of Computer Science, Vol. 8, Issue 12 · 20 Dec 2012 · 6,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractTesting Randomness: Poker Test with Hands of Three NumbersWael Mohamed Fawaz Abdel-Rehim, Ismail Amr Ismail, Ehab MorsyProblem statement: The problem of testing randomness is motivated by the need to evaluate of the quality of different random number generators used by many practical applications including computer simulations, cryptography and communications industry. In particular, the quality of the randomness of the generated numbers affects the quality of such applications. In this study we focus on one of the … …Journal of Computer Science, Vol. 8, Issue 8 · 30 Jul 2012 · 9,760 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeech Compression of Thai Dialects with Low-Bit-Rate Speech CodersSuphattharachai ChomphanProblem statement: In modern speech communication at low bit rate, speech coding deteriorates the characteristics of the coded speech significantly. Considering the dialects in Thai, the coding quality of four main dialects spoken by Thai people residing in four core region including central, north, northeast and south regions has not been studied. Approach: This study presents a comparative study of … …American Journal of Applied Sciences, Vol. 9, Issue 8 · 14 Jul 2012 · 6,868 accessesView PDFCite
Research ArticleOpen accessIn the abstractThreat of the Health Quality of Garden Produces Linked to Pollution by Toxic Metals on Some Gardening Sites of BeninKoumolou Luc, Edorh A. Patrick, Agbandji Lucien et al.Problem statement: Water and soil are vital resources used in agriculture. Current data establish a link between the pollution of soil, water and public health. For this reason, this study attempted to establish a link between the level of pollution of garden sites in lead (Pb), Cadmium (Cd) and Arsenic (As) and the health quality of vegetables grown there, through … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 23 Apr 2012 · 7,668 accessesView PDFCite
Research ArticleOpen accessIn the abstractSatisfaction with Knowledge and Competencies: A Multi-Country Study of Employers and Business GraduatesAna Azevedo, Doris Gomezelj Omerzel, Jane Andrews et al.Problem statement: This study critically discusses findings from a research project involving four European countries. The project had two main aims. The first was to develop a systematic procedure for assessing the balance between knowledge and competencies acquired in higher, further and vocational education and the specific needs of the labor market. The second aim was to develop and test … …American Journal of Economics and Business Administration, Vol. 4, Issue 1 · 14 Jan 2012 · 15,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeech Compression for Noise-Corrupted Thai DialectsSuphattharachai ChomphanProblem statement: Dialects of Thai are quite different in the speaking styles. Environmental noises play an important role in corrupting the communication speech quality. Two factors affect the coded speech in the present speech communication. It is necessary to investigate how the two factors influence on the speech compression. Approach: In this study, the Multi-Pulse based Code Excited Linear Predictive … …American Journal of Applied Sciences, Vol. 9, Issue 3 · 9 Jan 2012 · 7,241 accessesView PDFCite
