Research ArticleOpen accessAll words, across the recordA Hybridized BERT-Based Approach for Crime News Collection and Classification from Online NewspapersAshour Ali, Shahrul Azman Mohd Noah, Lailatul Qadri Zakaria, Saeed Amer Al AmeriCrime news analysis is crucial for understanding criminal activity, enhancing public safety, and informing policy decisions. The exponential growth and unstructured nature of online news articles, however, present significant challenges for efficient and accurate information extraction. This study aims to enhance the efficiency and accuracy of crime news data collection and classification through advanced Natural Language Processing (NLP) techniques and … …Journal of Computer Science, Vol. 21, Issue 9 · 16 Oct 2025 · 2,288 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Block-Based Multi-Scale Background Extraction AlgorithmSeyed Hashem Davarpanah, Fatimah Khalid, Maryam GolchinProblem statement: To extract the moving objects, vision-based surveillance systems subtract the current image from a predefined background image. The efficiency of these systems mainly depends on accuracy of the extracted background image. It should be able to adapt to the changes continuously. In addition, especially in real-time applications the time complexity of this adaptation is a critical matter. Approach: … …Journal of Computer Science, Vol. 6, Issue 12 · 6 Nov 2010 · 7,213 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHeterogeneous Modeling, Identification and Simulation of Activated Sludge ProcessesIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem statement: The activated sludge system is a complex dynamic process and must account for a large number of reactions between large numbers of components. There is necessity for simulation models which describe the dynamic behavior of the activated sludge process. The application of the models in most treatment plants is limited due to lack of appropriate data acquisition and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,592 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordModeling of Particle Separation in Bends of Rectangular Cross-sectionBingtao ZhaoA new theoretical model for predicting particle separation efficiency in bends is developed based on the investigation of flow pattern, the critical particle size separation theory and the boundary layer separation theory. The radial particle concentration gradient, instead of the usually assumed uniform radial particle concentration within the bends, is considered in this mathematical model. The local particle concentration and … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,852 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordStudy of Au/n-Ti2S/p-Si/Al Schottky-Type Thin Film Heterojunction Solar Cells: Computer Simulation ModelingAli IbrahimThe Au/n-Ti2S/p-Si/Al heterojunction with intrinsic thin-layer solar cells were analyzed by AFORS-HET software program. Thickness of the emitter intrinsic layer and the interface state density of such cells were studied. In which, the intrinsic layer inserted between the Ti2S and crystalline p-type silicon substrate, reduce the interface state density. The thinner intrinsic layer is better than thicker one, when the … …American Journal of Applied Sciences, Vol. 12, Issue 4 · 3 Jun 2015 · 6,282 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordCost-Effective Energy Refurbishment of Health Care Facilities in Heating Dominated Climates of Italian Backcountry. The Case Study of the Hospital Veneziale of IserniaRosa Francesca De Masi, Fabrizio Ascione, Gennaro Sosto, Giuseppe Peter VanoliMaximizing energy efficiency within hospitals and healthcare facilities is a major challenge for sustainable development and energy saving objectives. In this study, the case study of the public hospital of Isernia (Italian backcountry city) is proposed, being typical of the hospital building stock developed in reinforced concrete all around Italy in the last 40 years. Starting from deep on-site investigations, … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 25 Sep 2017 · 8,352 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordKINETIC MODELLING OF CONTINUOUS-MIX ANAEROBIC REACTORS OPERATING UNDER DIURNALLY CYCLIC TEMPERATURE ENVIRONMENTE. A. Echiegu, A. E. GhalyA two-culture dynamic model which incorporated the effects of diurnally cyclic temperature was developed and used to predict the dynamic response of anaerobic reactors operated on dairy manure under two diurnally cyclic temperature ranges of 20-40°C and 15-25°C which represent the summer and winter in Nigeria. The digesters were operated at various hydraulic retention times and solid concentrations and some … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 2 · 29 Aug 2014 · 7,290 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA NEW AIR CONDITIONING SYSTEM FAN MODEL BASED ON NUMERICAL ANALYSISNabil Nassif, Raymond Tesiero, Nihal AlRaeesA large portion of energy use in buildings is attributed to air movement devices. Accurate estimation of fan performance is a key element in maximizing fan efficiency. This study proposes a new fan model that can be used in several applications such as optimization and fault detection and can also be incorporated into any commercial building models. The model uses … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 1 · 14 Mar 2014 · 8,183 accessesView PDFCite
