DorvloThe use of Web-based instruction (WBI) and with the availability of well-structured Course Management Tools there seems to be a prospectus of improving both the classroom and distance educations using e-Learning principle[1,2]. As the instructor community plays a central role in all education processes we are motivated to study the level of their cooperation with respect to applying WBI through … …Journal of Social Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,368 accessesView PDF Cite

Belle, Nacelle Collins, Andries JordaanWetlands are a form of natural capital which provide services that improve the welbeing of the local community. Unfortunately many wetlands have been degraded before their values and functions were realised. Using a system thing appraoach and a mixed research method, this article collected primary data from 176 respondents using questionnaires. Besides, 21 wetlands were observed using field observation data … …American Journal of Environmental Sciences, Vol. 13, Issue 5 · 12 Oct 2017 · 7,972 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSynthesis and Characterization of Au@TiO2 NWs and their Catalytic Activity by Water Splitting: A Comparative Study with Degussa P25Abniel Machín, María Cotto, José Ducongé et al.Different amount of gold nanoparticles (1, 3, 5, 10 wt%) were deposited on the surface of synthesized titanium oxide nanowires (TiO2 NWs) and Degussa P25 (TiO2-P25). The results evidenced the presence of small and dispersed gold particles on the surface of TiO2 NWs and TiO2-P25 and an increase in the specific surface area of all the composites. The photocatalytic activity … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 6 Jun 2017 · 8,427 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordContribution of Remote Sensing in the Estimation of the Populations Living in Areas with Risk of Gully Erosion in Kinshasa (D.R. Congo). Case of Selembao TownshipKayembe wa Kayembe Matthieu, Ngoy Ndombe Alain, Makanzu Imwangana Fils et al.This paper proposes a methodology combining very high spatial resolution satellite image, GIS and field surveys to estimate the number of people living in areas at (high) risk of landslides or gully erosion in Selembao (Kinshasa). It also gives their socio-economic characteristics. Results show that 185,000 out of the 314,699 inhabitants estimated in Selembao (58.3% of the population) live in … …Current Research in Geoscience, Vol. 6, Issue 1 · 6 Jun 2016 · 8,612 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSpline Estimator for Bi-Responses and Multi-Predictors Nonparametric Regression Model in Case of Longitudinal DataAdji Achmad Rinaldo Fernandes, I Nyoman Budiantara, Bambang Widjanarko Otok, SuhartonoNonparametric regression approach is used when the shape of the curve regression is unknown. The spline estimator approach for longitudinal data can accommodate the correlation between observations within the same subject, which is not found in the cross-section data, so that the autocorrelation assumption problem can be resolved. On the other hand, with bi-responses approach, it will accommodate any correlation … …Journal of Mathematics and Statistics, Vol. 11, Issue 2 · 8 Oct 2015 · 7,337 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordTHE RURAL TOURISM AS DEVELOPMENT OPPORTUNITY OR FARMS. THE CASE OF DIRECT SALES IN SICILYFilippo Sgroi, Anna Maria Di Trapani, Riccardo Testa, Salvatore TudiscaTourism has an important role modifying rural communities in their environmental, economic, social and cultural structures, processes and dynamics. In this context rural tourism plays a primary role because it is not the rural product that reaches the consumer in the purchase point, but it is the consumer (tourist) that has to move towards tourist destination to enjoy the product. … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 21 Jun 2014 · 8,164 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA CASE FOR HYBRID INSTRUCTION ENCODING FOR REDUCING CODE SIZE IN EMBEDDED SYSTEM-ON-CHIPS BASED ON RISC PROCESSOR CORESGovindarajalu Bakthavatsalam, K. M. MehataEmbedded computing differs from general purpose computing in several aspects. In most embedded systems, size, cost and power consumption are more important than performance. In embedded System-on-Chips (SoC), memory is a scarce resource and it poses constraints on chip space, cost and power consumption. Whereas fixed instruction length feature of RISC architecture simplifies instruction decoding and pipeline implementation, its undesirable … …Journal of Computer Science, Vol. 10, Issue 3 · 23 Nov 2013 · 6,825 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSTRATEGY PATTERNS PREDICTION MODELAram Baruch Gonzalez Perez, Jorge Adolfo Ramirez UrestiMulti-agent systems are broadly known for being able to simulate real-life situations which require the interaction and cooperation of individuals. Opponent modeling can be used along with multi-agent systems to model complex situations such as competitions like soccer games. In this study, a model for predicting opponent moves based on their target is presented. The model is composed by an … …Journal of Computer Science, Vol. 10, Issue 1 · 12 Nov 2013 · 6,854 accessesView PDF Cite

The reasons for the loss of fertility are various and related to irreversible damage caused to the cells during the freeze-thaw process. An alternative to conventional cryopreservation represents the use of chilled bull semen, preventing the damage associated with freezing, thereby guaranteeing greater sperm viability. … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 2 Feb 2013 · 8,681 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAssessing Convergence of the Markov Chain Monte Carlo Method in Multivariate CaseDenismar Alves Nogueira, Thelma Safadi, Daniel Furtado Ferreira, Eric Batista FerreiraThe formal convergence diagnosis of the Markov Chain Monte Carlo (MCMC) is made using univariate and multivariate criteria. In 1998, a multivariate extension of the univariate criterion of multiple sequences was proposed. However, due to some problems of that multivariate criterion, an alternative form of calculation was proposed in addition to the two new alternatives for multivariate convergence criteria.
