Research ArticleOpen accessIn the abstractOld and Modern Construction Materials In Yemen: The Effect In Building Construction In Sana’aISSA A.M. Al_Kahtani, Suhaib Y.K. Al-DarziSana’a city in Yemen is one of the oldest cities in the worlds, which has different forms of building built with different types of materials. In the present work, the old and new forms of building construction and the building materials used in Sana’a, the sources available for the new material, the effects of new material usage on building forms … …Journal of Social Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 9,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Swarm-based Distance Vector Routing to Support Multiple Quality of Service (QoS) Metrics in Mobile Adhoc NetworksR. Asokan, A. M. Natarajan, A. NivethaQuality of Service support for Mobile Ad-hoc Networks is a challenging task due to dynamic topology and limited resource. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. A fundamental problem in QoS routing is to find a path between a source and destination that satisfies two or more … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,671 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Spatial-Temporal Variability of Nitrates in a Section of the Cuneo Plain (North West Italy)Massimo Vincenzo Civita, Adriano Fiorucci, Bartolomeo VignaThe study of an aquifer system is very important, but also very complicated because of the high temporal and spatial variabilities of a system and because of the phenomena that are at play within the system. It is from these problems that the necessity arises of finding methods that are able to extend point knowledge to an entire area, while … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Reservoir Operation Using Combined Genetic Algorithm and Wavelet Transform MethodL. Ebrahimi, G.A. Barani, H. EbrahimiDams construction are high cost projects, and therefore, optimal using of reservoir storages behind dams is an important task in water resources management. In last decades, various optimization techniques have been used for reservoir operation. Among the new methods, Genetic Algorithm (GA) and wavelet transform (WT) have been widely used in recent years. In this study, GA as well as … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 3 · 30 Sep 2007 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractBreaking out: The Dynamics of Immigrant Owned BusinessesShahamak RezaeiAs far as integration policy in a Danish context is concerned a phenomenon have been observed during the last decade: Immigrant businesses are spreading rapidly in the country, dominating certain business lines in deprived inner city areas. According to registry and survey data, most immigrant businesses - and particularly those owned by immigrants from less developed countries in Asia, the … …Journal of Social Sciences, Vol. 3, Issue 2 · 30 Jun 2007 · 7,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy-GAs Model for Determining Varied Irrigation EfficiencyAnongrit Kangrang, Chavalit ChaleeraktrakoonIrrigation efficiency is necessary information in water resource management. We proposed fuzzy sets approach for estimating varied irrigation efficiency. Genetic algorithms technique was applied to calibrate membership function of fuzzy model. The fuzzy sets technique considered the uncertainty of the available water resource and required area as the input variables. The approach model was applied to determine the fluctuated irrigation … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 7,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Variation and Relationship Between Turkish Flint Maize Landraces by RAPD MarkersA. OkumusA comparative characterization of 17 flint maize landraces (Zea mays L.) was carried out using RAPD markers. Fourteen primers giving reliable and consistent polymorphic bands amplified 125 fragments (89%) with an average of 8.90 fragment per primer. Genetic variation in 17 maize landraces was characterized based on dissimilarity matrix by UPGMA dendogram which has no association into distinct grouping with … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 7,982 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneration of Five New Musa Hybrids With Resistance To Black Sigatoka and High YieldRicardo Hernández, Teresa Ramírez, Juan Carlos Noa-Carrazana et al.The ability to identify genetic variation is indispensable to effective management and use of genetic resources. This work is the first approach concerning to generation and genetic differentiation of new Musa hybrid lines obtained in INIVIT (Cuba), crossing Musa acuminata male diploid (AA) x female triploid (ABB), genotypes selected by their resistant character to pests and diseases. From the obtained … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 8,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Scheduling Algorithm Based on Petri Nets and Simulated AnnealingRachida Hadiby Ghoul, Abdelhamid Benjelloul, Sihem Kechida, Hicham TebbikhThis study aims at presenting a hybrid Flexible Manufacturing System "HFMS" short-term scheduling problem. Based on the art state of general scheduling algorithms, we present the meta-heuristic, we have decided to apply for a given example of HFMS. That was the study of Simulated Annealing Algorithm SA. The HFMS model based on hierarchical Petri nets, was used to represent static … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractTowards an Exclusion Mutual Tolerant Algorithm to FailuresM. Senouci, A. Liazid, D. BenhamamouchThe distributed algorithmic is widely used in various economic and industrial fields as finance, medical, industry, telecommunication. New technologies are increasing rapidly. From now on, applications must associate two conditions: auto-execution on heterogeneous grid computers, on the one hand and on the other hand, satisfaction of the temporal and safety constraints. Hence this paper deals with performing an algorithm based … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 6,730 accessesView PDFCite
