Research ArticleOpen accessIn the abstractMemory Storage Issues of Temporal Database Applications on Relational Database Management SystemsSami M. Halawani, Nashwan A. Al-RomemaProblem statement: Many existing database applications manage time-varying data. These database applications are referred to as temporal databases or time-oriented database applications that are considered as repositories of time-dependent data. Many proposals have been introduced for developing time-oriented database applications, some of which suggest building support for Temporal Database Management Systems (TDBMS) on top of existing non-temporal DBMSs, while others … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Predictability of Risk Box Approach by Genetic Programming Method for Bankruptcy PredictionAlireza Bahiraie, Noor Akma bt Ibrahim, A. K.M. AzharProblem statement: Theoretical based data representation is an important tool for model selection and interpretations in bankruptcy analysis since the numerical representation are much less transparent. Some methodological problems concerning financial ratios such as non-proportionality, non-asymetricity, non-scalicity are solved in this study and we presented a complementary technique for empirical analysis of financial ratios and bankruptcy risk. Approach: This study … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Event-Based Methodology to Generate Class Diagrams and its Empirical EvaluationSandeep K. Singh, Sangeeta Sabharwal, J. P. GuptaProblem statement: Event-based systems have importance in many application domains ranging from real time monitoring systems in production, logistics, medical devices and networking to complex event processing in finance and security. The increasing popularity of Event-based systems has opened new challenging issues for them. One such issue is to carry out requirements analysis of event-based systems and build conceptual models. … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,626 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Resources Management in Various Scenarios Using Numerical ModelS. Askari Marnani, M. Chitsazan, Y. Mirzaei, B. JahandidehProblem statement: Iran is an arid country and only small percent of its water demand is met by rainfall. At present, about 55% of Iran's water being supplied by aquifers and 45% from surface water. Population growth, joint with economic development and rapid growth in industry and farming, has caused a vast increase in demand for water in Iran. But … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 13,769 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Learning Styles on Education and the Teaching ProcessIbrahim Yasar KazuProblem statement: It is of great importance that individuals actively participate in the learning process; that, starting from the early ages, their awareness be raised about the efficiency of the learning styles in developing their academic success and self-confidence; and that the learning styles they have be determined. For this reason, this study aimed to reveal the learning styles having … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 17,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Kinetic Correction Coefficient of Fluid Flow Using a Generic Multiple Orifice Physical Scale Model StructureEmmanuel M. AdigioProblem statement: Diesel particulate filters are fast becoming integral parts of diesel engines, light and heavy duty, due to their potential in the reduction of particulate matter from exhaust gases and their noise muffling property. Consequently, several researchers are developing mathematical models for the study of fluid flow through the filter substrate and in the aiding of filter systems design. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultistage Development of Müller-Achenbach model for Shape Memory AlloySimin Ataollahi Oshkovr, Nik Abdullah Nik Mohamed, Che Husna Azhari et al.This research focused on the conceptual development of constitutive Müller-Achenbach model and proceeds to construct a model based on phase transition under changing temperature and load for variants of martensite in shape memory alloy CuAlNi (Copper-aluminum-nickel). Problem statement: Motivation of this research is rare information of a variant of martensite phase (M++) and prediction of the shape recovery of shape … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,534 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling the Semantics of States and State MachinesSabah Al-FedaghiA system’s behavior is typically specified through models such as state diagrams that describe how the system should behave. According to researchers, it is not clear what a state actually represents regarding the system to be modeled. Standards do not provide adequate definitions of or sufficient guidance on the use of states. Studies show these inconsistencies can lead to poor … …Journal of Computer Science, Vol. 16, Issue 7 · 14 Jul 2020 · 6,974 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEnhancing Quality in Agile Requirement Elicitation ProcessNavneet Kaur, Moshiur Bhuiyan, P.W.C. Prasad et al.Eliciting requirements is one of the key aspects of the software development life cycle. Incorrect determination of the requirements can lead to the failure of the projects. Traditional waterfall method does not accommodate changing requirements easily while agile methodology welcomes the changing requirements even at the later phases of the development life cycle. The aim of the research is to … …American Journal of Applied Sciences, Vol. 16, Issue 1 · 27 Feb 2019 · 8,610 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOntological Framework for Object-Oriented Analysis and DesignPrabodha Tilakaratna, Jayantha RajapakseRegardless of the large number of Object-Oriented (OO) modeling languages currently being used in the Information Systems (IS) modeling process, unavailability of an OO modeling language that can be used in both the analysis and design phases disintegrates the two phases. The problem is, such disintegration can lead to a high level of missing information in the real world system … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 3 · 14 Sep 2012 · 8,082 accessesView PDFCite
