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 abstractAn Analysis of the Output and Employment Conversion Matrices of Australia's EconomyAbbas Valadkhani, Tim RobinsonBased on two snapshots taken from the Australian economy, this study quantifies the impacts of final demand aggregates on output and employment in various sectors using the 1989 and 1997 conversion matrices. The sectoral output and employment are linked with final demand deliveries in such a way that one can measure the impacts on changes in each component of aggregate … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Environmental Performance-HSEQ Management System, Regarding the International and Iranian Oil and Gas General ContractorsJ. Nouri, M. Abbasspour, E. Roayaei, H. NikoomaramThe ever-increasing significance of the health, safety, environment and quality Management system has led general contractors including those involved in the oil and gas industry to place the implementation of this integrated system on their agenda, in a way that the implementation and execution of this system is considered as one of their operation and development strategies. The purpose of … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Operational Features of Pumping Stations Equiped with Parallel-Connected Centrifugal Pumps for Land-ReclamationKhalid S. Al-RababaThe required water supply of a pump could be provided by means of different combinations of pressure piping and pumping units at different operational costs. The basic indices describing the operational modes for the individual and group pumping units, including the values of the efficiency, are computed. The adequacy of the calculational results that based on the developed mathematical models … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractLaser Interaction and Related Plasma PhenomenaFrederick Osman, Peter Evans, Peter Toups et al.Computations are to be performed using the laser driven inertial fusion energy option based on volume ignition with the natural adiabatic self-similarity compression and expansion hydrodynamics [1]. The numerical work includes the establishing of a multi-branch reaction code to be used for simultaneous fusion reactions of D-D, D-T D-He3 and mutual nuclear reaction products. This will permit the studies of … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,816 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 abstractDepth Estimation of 2-D Magnetic Anomalous Sources by Using Euler Deconvolution MethodM. G.E. Dawi, Liu Tianyou, Shi Hui, Luo DapengEuler deconvolution method is the method of depth estimation which is best suited for anomalies caused by isolating and multiple anomalous sources. In the present study, algorithmic programs based on generalizing linear inverse theory, uses a least square sense to solve for Euler’s equation is being written. The Euler technique that can estimate the location of a simple body from … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware Design of Wireless Physical Token Ring System for Mobile and Cell CommunicationNidal F. Shilbayeh, Mahmoud Z. IskandaraniA wireless network system based on an infrared and Laser scanning Physical Token Ring architecture (W-PTRS) was designed, built and tested successfully. The network provides a different way of utilizing the concept of a token ring network but with a higher efficiency related to the speed of data transfer and the ability to parallel process client-server requests leading to a … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Investigation of the Nature Properties of PlasmaPeter Evans, Frederick Osman, Heinrich HoraThis study presents the characteristics of the plasma and the effect of the laser beam to best suit the plasma model behavior. Special attention is paid to the “Genuine” Two Fluid Model and the ponder-motive and transient forces. These models are translated into a numerical study of the parameters, such as the electric field density and temperature distributions once electromagnetic … …American Journal of Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2004 · 6,566 accessesView PDFCite
