Research ArticleOpen accessEvery word in the titleObserved Abrupt Changes in Minimum and Maximum Temperatures in Jordan in the 20th CenturyMahmoud M. SmadiThis study examines changes in annual and seasonal mean (minimum and maximum) temperatures variations in Jordan during the 20th century. The analyses focus on the time series records at the Amman Airport Meteorological (AAM) station. The occurrence of abrupt changes and trends were examined using cumulative sum charts (CUSUM) and bootstrapping and the Mann-Kendall rank test. Statistically significant abrupt changes … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 7,931 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEvaluation of Temperature Trend In Contaminated Tidal Flat In The Ariake Sea, JapanM. A. Moqsud, Shigenori Hayashi, y. j. Du, Daisuke suetsuguThermal environment of the tidal flat is one of the major parts of the contaminated geo-environment of the Ariake Sea. The activities of marine ecosystem in tidal flats depend strongly on the thermal environment. In order to get a clear idea about the thermal environment of the tidal flats of the Ariake Sea, two study areas, Iida and Higashiyoka tidal … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,750 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Study On An Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFT) Fabricated By Dry Pressing MethodA. Rifau, Z. Zainal, D. Mutharasu et al.An intermediate temperature solid oxide fuel cell (IT-SOFC) has been developed by using the dry pressing method. Widely studied materials were used for anode and cathode and SDC based electrolyte was used in this study. The cells were fabricated by dry-pressed at different pressures using a die without any binding material, a known amount of three electrode materials in powder … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 6,970 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTowards a Temporal Multilevel Secure Database (TMSDB)Ramzi A. Haraty, Natalie BekaiiStandard Relational Databases are used to store the state of reality at a single moment of time. Temporal Databases are used to store Time-Varying Data. Multilevel Secure Databases are used to securely store highly sensitive data. Each of these databases serves its purpose well, but if we were to model the temporal and sensitive aspect of the real world data, … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,714 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Comparison of Spatio-Temporal Bayesian Models for Reconstruction of Rainfall Fields in a Cloud Seeding ExperimentSujit k. sahu, Giovanna Jona Lasinio, Arianna orasi, Kanti V. MardiaIn response to the drought experienced in Southern Italy a rain seeding project has been setup and developed during the years 1989-1994. The initiative was taken with the purpose of applying existing methods of rain enhancement technology to regions of south Italy including Puglia. The aim of this study is to provide statistical support for the evaluation of the experimental … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,813 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePetri Net Based Spatio-temporal Relationships for Moving ObjectsYong-shan Liu, Zhong-xiao HaoThis study presents the spatio-temporal constraint relationships of moving objects by employing Petri Net technology. The spatial constraints of moving objects are first presented in this study based on the V4I[1] theory, then the temporal constraints for moving objects are presented by applying this theory to temporal aspect. With the proposing of Moving Object Petri Net (MOPN) and Spatial Constraint … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,239 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Look to Adaptive Temporal Radial Basis Function Applied in Speech RecognitionMesbahi Larbi, Benyettou AbdelkaderThis study presents new contribution towards the Adaptive Temporal Radial Basis Function (ATRBF) applied to Continuous speech recognition, in particular the recognition of phonemes like Timit Corpus. ATRBF combines features from Time Delay Neural Network (TDNN) and the advantages of Radial Basis Function (RBF). The capacity to detect the acoustic features and their independent temporal report of the temporal localisation … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Dec 2005 · 7,688 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOn the Effect of Counterface Materials on Interface Temperature and Friction Coefficient of GFRE Composite Under Dry Sliding ContactN. S.M. El-Tayeb, B. F. Yousif, P. V. BrevernNowadays, there is an increase interest in polymeric composite materials for high-performance in many industrial applications. In other words, the tribo-studies on polymeric materials are growing fast to enhance the polymeric products such as bearings, seals, ring and bushes. The current work presents an attempt to study the correlation between the type of counterface material and frictional heating at the … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,026 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFurther Improvements in Temperature Calculation During Cooling of Fish PackagesF. A. Ansari, K. A. Abbas, J. Bakar et al.In an earlier study, it was demonstrated that the empirical approach used to calculate the surface film conductance resulted into a higher value compared to those obtained from the other methods available in the literature. During further investigations, surface film conductance values were found to gradually decrease with a fall in temperature. When this non-linear variation was used to develop … …American Journal of Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2004 · 6,854 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance Study of Threshold Variations in Temporal Decision Systems for Routing in Vehicular Ad hoc NetworksB. S. Shylaja, V. Mary Anita Rajam, V. Uma Maheswari, Arul SiromoneyProblem statement: Route maintenance and re-discovery are expensive in signaling and computation for routing in Vehicular Ad hoc Networks (VANETs). Hence it was desirable to choose the optimal route during the route selection phase. Approach: In this study, the threshold-based routing protocol β-wt uses the notion of threshold from variable precision rough sets. This protocol was used to evaluate routing … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,893 accessesView PDFCite
