Research ArticleOpen accessIn the abstractArtificial Neural Networks Based Modeling and Control of Continuous Stirred Tank ReactorR. Suja Mani Malar, T. ThyagarajanContinuous Stirred Tank Reactor (CSTR) is one of the common reactors in chemical plant. Problem statement: Developing a model incorporating the nonlinear dynamics of the system warrants lot of computation. An efficient control of the product concentration can be achieved only through accurate model. Approach: In this study, attempts were made to alleviate the above mentioned problem using &#34Artificial Intelligence&#34 … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractReduction of Ammonia Loss by Mixing Urea with Liquid Humic and Fulvic Acids Isolated from Tropical Peat SoilSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid et al.Problem statement: Fertilizer N use efficiency is reduced by ammonia volatilization. Under low soil CEC and high pH, N from soil solution is released to the atmosphere. Ammonia loss due to low worldwide N use efficiency (33%) has been implicated in global warming. Thus, the objectives of this laboratory study were to evaluate the effectiveness of liquid humic and fulvic … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimate Change in Jordan: A Comprehensive Examination ApproachMoshrik R. Hamdi, Mahmoud Abu-Allaban, Ammar Al-Shayeb et al.Problem statement: Jordan is experiencing harsh water shortage in different parts of the country due to high fluctuations in annual precipitation; the only source of water. In addition, heat waves are becoming more frequent in the region. Precipitation decrement and summer heat waves are being blamed on global warming. This study aimed to detect trends in weather parameters in Jordan. … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 9,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Speech Recognition Using Fusion Techniques and Adaptive FilteringS. A.R. Al-Haddad, S. A. Samad, A. Hussain et al.The study proposes an algorithm for noise cancellation by using recursive least square (RLS) and pattern recognition by using fusion method of Dynamic Time Warping (DTW) and Hidden Markov Model (HMM). Speech signals are often corrupted with background noise and the changes in signal characteristics could be fast. These issues are especially important for robust speech recognition. Robustness is a … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,993 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Thermal Infrared Imagery (TIR) for Illustrating the Submarine Groundwater Discharge into the Eastern Shoreline of the Dead Sea-JordanEmad Akawwi, Abdallah Al-Zouabi, Maher Kakish et al.Many of thermal anomalies that are indicator of discharge zones of warmer water were observed along the Dead Sea shoreline at the areas of Zarka Ma’in, Zara and Al-Mujeb. The groundwater discharge locations were mapped along eastern shores of the Dead Sea by using aerial thermal infrared imagery (λ = 8-13 µm). A digital thermal infrared camera was used for … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Views of Carbon Tax in KoreaHeon-Goo KimTo comply with the UNFCCC agreement, many countries are expected to make efforts to reduce the greenhouse gas emission level down to 1990 by the year of 2012. The agreement is intended to reduce the consumption of fossil fuel that causes the greenhouse effect. The global warming has been accelerated by the greenhouse effect resulted from the CO2 emission and … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,891 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Green House Gases (GHG) Emissions from Oil Production Facilities at Northern Kuwait Oilfields: Simulated ResultsKhaireyah Kh. AL-Hamad, V. Nassehi, A.R. KhanAir pollution and its effects on the ecosystem has been a source of concern for many environmental pollution organizations in the world. In particular climatologists who are not directly involved in petroleum industry sometimes express concerns about the environmental impacts of gaseous emissions from flaring at various despised points. For environmental and resource conservation reasons, flaring should always be minimized … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Sulfur Dioxide (SO2) Concentration Levels from the Mina Al-Fahal Refinery in Oman Using Artificial Neural NetworksSabah A. Abdul-Wahab, Saleh M. Al-AlawiIn this investigation, two Artificial Neural Network (ANN) models were applied for predicting ground-level sulfur dioxide (SO2) in the Sultanate of Oman in order to provide an early warning advisory for the protection of public health. The objective of the first model (Model I) was to use ANN to predict sulfur dioxide (SO2) levels at certain receptors from the Mina … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 7,385 accessesView PDFCite

Research ArticleOpen accessIn the abstractFatal Pulmonary Hemorrhage Through Fiberoptic Broncoscopy in a Well Controlled Diabetic Female With MucormycosisP. Di Carlo, D. Cabibi, A. Mazzola et al.A rare case of invasive pulmonary mucormycosis complicated by fatal massive haemoptysis through bronchoscopy in a patient with a well controlled diabetes is reported. Histological features of infection are reported and the characteristic aspects of the staining are discussed. Fiberoptic bronchoscopy revealed bilateral obstruction of the segmental bronchi and fatal massive bleeding occurring because of biopsy sampling. Caution is warranted … …American Journal of Infectious Diseases, Vol. 4, Issue 3 · 30 Sep 2008 · 7,184 accessesView PDFCite
