Research ArticleOpen accessIn the abstractEnergy and Carbon Flux Coupling: Multi-ecosystem Comparisons Using Artificial Neural NetworkAssefa M. Melesse, Rodney S. HanleyA multi-ecosystems carbon flux simulation from energy fluxes is presented. A new statistical learning technique based on Artificial Neural Network (ANN) back propagation algorithm and multi-layer perceptron architecture was used in the CO2 simulation. Four input layers (net radiation, soil heat flux, sensible and latent heat flux) were used for training (calibration) and testing (verification) of model outputs. The 15-days … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractConsidering Environmental Externalities in Technology Selection: the Case of Urban Buses for AthensDimitrios A. GeorgakellosThe present study proposes a procedure for considering the environmental externalities in technology selection decision-making, based on the outcome of Life Cycle Assessments. Currently, even if there are several methods available for technology selection and purchasing, almost all of them seem to ignore the external cost associated with the candidates. The main features of the proposed model are its simplicity … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of a New Device, Automated Shower head on Water Conservation in Bath ShowersM. Shamsi, G. H.S. BonjarIn cosmopolitan areas and big cities of the world, shortage of drinking water during the peaks of consumption hours is a noticeable problem. Many people may not have piped water during these critical hours especially in summer times. To minimize this problem, an electronic control valve was designed and developed which saved about 70% of water in each showering session … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,201 accessesView PDFCite
Research ArticleOpen accessIn the abstractCivil Liberties and Computer MonitoringKevin Curran, Steven McIntyre, Hugo Meenan et al.Civil Liberties-the term used for the fundamental liberties and rights of a country's citizen is the right of free speech, thought and action. This is the fundamental building block of a democratic society. This research essay outlines the current measures western governments are taking to ensure our safety and the associated costs of civil and human rights. …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Computable General Equilibrium Model of Southern Region in Taiwan: The Impact of the Tainan Science-Based Industrial ParkChun-Chu Liu, Chia-Yon ChenThe primary modeling tools used to analyze regional economic issues include econometric forecasting models, fixed price Input-Output (I-O) multi-sector models, Social Accounting Matrix (SAM) and Computable General Equilibrium (CGE) models. CGE models combine the advantages of econometric, I-O models and SAM strengthening the theoretical basis of the modeling effort and thus enabling more precise policy analysis. The current CGE literature … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,210 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrom a Vicious Circle of Anxiety to a Virtuous Circle of Learning: Experience of Teaching Statistics to a Heterogeneous ClienteleMohammad Alauddin, James E. ButlerA considerable body of literature suggests that significant psychological barrier and anxiety characterize the teaching and learning process in statistics. This study investigates the incidence of statistics anxiety, the extent to which it can be overcome and the factors that contribute to the process of overcoming it. Self-study and overall teaching quality, amongst others, significantly contributed to this outcome. This … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,109 accessesView PDFCite
