Research ArticleOpen accessIn the abstractInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring Strategies for Parallel Computing of RS Data Assimilation with SWAP-GAShamim Akhter, Kiyoshi Honda, Yann Chemin, Putchong UthayopasAn agro-hydrological simulation model is useful for agriculture monitoring. One issue in running such model is parameter identification, especially when the target area is large such as provincial or country level. Remote Sensing (RS) provides us with useful information over large area. RS cannot observe input parameters of agro-hydrological models directly. However, a method to estimate input parameters of such … …Journal of Computer Science, Vol. 3, Issue 1 · 31 Jan 2007 · 7,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Total Dissolved Solids on Aquatic Organisms: A Review of Literature and Recommendation for Salmonid SpeciesPhyllis K. Weber-Scannell, Lawrence K. DuffyTotal dissolves solids (TDS) are naturally present in water or are the result of mining or some industrial treatment of water. TDS contain minerals and organic molecules that provide benefits such as nutrients or contaminants such as toxic metals and organic pollutants. Current regulations require the periodic monitoring of TDS, which is a measurement of inorganic salts, organic matter and … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Jan 2007 · 23,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplications of Real-time Reverse Transcription Polymerase Chain Reaction in Clinical Virology Laboratories for the Diagnosis of Human DiseasesR. Manojkumar, V. MrudulaEarly diagnosis that prevents further expansion of the causative agent and thereby aids control and eradication of infectious agents is critical for countries trying to obtain a particular disease free status. In these diagnostics speed is paramount, including the assay’s applicability, sensitivity, specificity, cost effectiveness and patentability. Real-time Reverse Transcription PCR (rRT-PCR) has revolutionized the field of molecular biology and … …American Journal of Infectious Diseases, Vol. 2, Issue 4 · 31 Dec 2006 · 6,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Environmental and Hydraulic Performance of Bio-Composite Revetment BlocksThamer A. Mohamed, Nor A. Alias, Abdul H. Ghazali, Mohd. S. JaafarIt is necessary to develop a concrete revetment block which can cater for environment and at the same time it will be effective in protecting river banks (stabilize the slope of banks) from scouring during flood. In the present study, the environmental and hydraulic performance of the proposed revetment block was evaluated through laboratory and field tests. The tested revetment … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Application of Agent Technology on the Power Flow of Iraqi Supper Grid NetworkShant K. Avakian, Afaneen Anwar, Ahmed N. AbdallaA study was conducted to improve the Iraqi National Control center by adapting the facilities of the agent technology and to obtain an automated control system for controlling and monitoring the electrical network. This study presents simulation results of practical agent in power flow control scenario applied to the Iraqi super grid network (400 kV). …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 6,723 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Harmonic Components on Transformer Losses of Sinusoidal Source Supplying Non-Linear LoadsI. Daut, H. S. Syafruddin, Rosnazri Ali et al.An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Transformers are major components in power systems. The increased losses due to harmonic distortion can cause excessive losses and hence abnormal temperature rise. The measurement of iron losses and copper losses of single-phase transformers is important in particular for transformers feeding nonlinear … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 8,398 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Detection and Classification Algorithm for Power Quality Disturbances using WaveletsC. Sharmeela, M. R. Mohan, G. Uma, J. BaskaranThis study presents a novel method to detect and classify power quality disturbances using wavelets. The proposed algorithm uses different wavelets each for a particular class of disturbance. The method uses wavelet filter banks in an effective way and does multiple filtering to detect the disturbances. A qualitative comparison of results shows the advantages and drawbacks of each wavelet when … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 6,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of Mirex Concentrations along the Southern Shorelines of the Great Lakes, USADennis A. Apeti, Gunnar G. lauensteinMirex is a persistent and toxic polychlorinated pesticide that has compromised environmental quality in the Great Lakes region since the 1960s. As a bioaccumulative and carcinogenic compound, mirex at its current levels in Lake Ontario is a concern because of the potential for trophic level transfer and biomagnification in top predators. As a part of the NOAA’s National Status and … …American Journal of Environmental Sciences, Vol. 2, Issue 3 · 30 Sep 2006 · 6,934 accessesView PDFCite
Research ArticleOpen accessIn the abstractVAR-models for Predicting BiodiversityTonio D. Bettista, S. A. Gattone, Mariagrzia GranturcoThe aim of this work is to introduce a methodology for monitoring diversity of a biological population by using the tool of diversity profiles. In particular, we develop a theory for studying the diversity profile along the temporal axis. We propose forecasting techniques for diversity profile by using the VAR model on multivariate time series of abundance vector and ARMA … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,175 accessesView PDFCite
