EditorialOpen accessIn the abstractData Mining in Time Series: Current Study and Future TrendTan Yan, Liudmila Ulanova, Ye Ouyang, Fengyuan XuTime series represent sequences of data points where usually their order is defined by the time when they were recorded. Thus, virtually any sequential recordings can be stored as time series: Stock prices, weather conditions, physical system parameters change, product quality monitoring, etc. This leads to ubiquity of time series in all scientific and practical fields (Esling and Agon, 2012); … …Journal of Computer Science, Vol. 10, Issue 12 · 26 Jan 2015 · 8,762 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrating Software Architecture Concepts into the MDA Platform with UML ProfileAdel Alti, Tahar Khammaci, Adel SmedaArchitecture Description Languages (ADLs) provide an abstract representation of software systems. Achieving a concrete mapping of such representation into the implementation is one of the principal aspects of MDA (Model Driven Architecture). Integration of ADLs within MDA confers to the MDA platform a higher level of abstraction and a degree of reuse of ADLs. Indeed they have significantly different platform … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparative Study of Mobility Models for Wireless Sensor NetworksAnas Abu TalebWireless sensor networks consist of hundreds or thousands of small, lightweight and low-powered sensor nodes that are deployed in the area of interest to collect information in an unattended manner. Since sensor nodes have limited battery, many research papers proposed techniques to enhance the performance and lifetime of wireless sensor networks. Using energy rich mobile sink to collect data from … …Journal of Computer Science, Vol. 14, Issue 10 · 10 Oct 2018 · 8,068 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Question Answering System based on a Hybrid TechniqueAyatallah Gamal Abass, Sameh Abd El-Ghany, Ahmed Abo ElfetohQuestion Answering (QA) is a specialized form of information retrieval characterized by information needs that are expressed as natural language statements or questions. Query expansion is an approach which is used to extend question key words with new related words that are not included in question. In this study, anew association rule based question processing model is introduced. This model … …Journal of Computer Science, Vol. 14, Issue 9 · 15 Aug 2018 · 7,983 accessesView PDFCite

Research ArticleOpen accessIn the abstractModeling 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 · 6,979 accessesView PDFCite
