Research ArticleOpen accessAll words, across the recordDeveloping the Environment of Information Technology Education using Cloud Computing InfrastructureChen-Feng Wu, Liang-Pang HuangThe education of Information Technology (IT) in Taiwan has been promoted since 1997. However, there were still problems with the current environment of IT education. Problem statement: The major problem was that students were unable to practice after school with the same environment and there was no appropriate space to save their files for students, so it was not convenient … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 1 Aug 2011 · 7,656 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Accuracy of MultiplesStauropoulos Antonios, Samaras Ioannis, Arsenos PanagiotisProblem statement: Equity valuation with the use of multiples is widely used by academics and practitioners concerning its functionality. This study aims to explore the sensitivity of three multiples in terms of accuracy. Approach: Price-to-Sales (P/S) multiple, the price-to-book value of equity (P/B) multiple and the Price-to-Earnings (P/E) multiple are three multiples under consideration, using both current and one-year-ahead earnings … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 19 Jul 2011 · 6,838 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordModeling of Signal Generation Function and Electron Penetration Effects on the EBIC Signal of Schottky diodes of GeBeggah Yamina, Lahreche AbderezzekThe present study shows that simple forms for the generation functions, if connected to appropriate electronic path (electron range), can be successfully used to describe the collection efficiency in EBIC devices. Both uniform and point-like source generation functions are considered here and for which two phenomenological electronic paths, depending on the incident beam energy, are obtained. Complexities that might arise … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 6,584 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDuration Modeling in Undergraduate Econometrics Curriculum via ExcelIsmail H. GencThe main goal of an Econometrics course is to prepare students for more advanced levels of study and make them able to cope with the empirical problems they are likely to face. In recent years, there has been a tendency to purge merely theoretical topics from the econometric textbooks by including only time honored methods. Survival analysis, however, has so … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,055 accessesView PDF Cite
