Research ArticleOpen accessAll words, across the recordMining Sports Articles using Cuckoo Search and Tabu Search with SMOTE Preprocessing TechniqueWaheeda AlmayyanSentiment analysis is one of the most popular domains for natural language text classification, crucial for improving information extraction. However, massive data availability is one of the biggest problems for opinion mining due to accuracy considerations. Selecting high discriminative features from an opinion mining database is still an ongoing research topic. This study presents a two-stage heuristic feature selection method … …Journal of Computer Science, Vol. 17, Issue 3 · 12 Mar 2021 · 6,538 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEvaluation of Fire Effects on Reinforced Concrete Columns Using Finite Element MethodSajjad Sayyar Roudsari, Taher M. Abu-LebdehIn this paper, four different Reinforced Concrete (RC) columns are analyzed with Finite Element (FE) ABAQUS software and validated experimentally. One of the RC columns, the control specimen, is subjected to only compressive force applied at both ends of the column, while the other three models were loaded under both compressive force and fire load. The temperature is applied to … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 20 Jun 2019 · 7,601 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSparse Sliced Inverse Quantile RegressionAli Alkenani, Tahir R. DikheelThe current paper proposes the sliced inverse quantile regression method (SIQR). In addition to the latter this study proposes both the sparse sliced inverse quantile regression method with Lasso (LSIQR) and Adaptive Lasso (ALSIQR) penalties. This article introduces a comprehensive study of SIQR and sparse SIQR. The simulation and real data analysis have been employed to check the performance of … …Journal of Mathematics and Statistics, Vol. 12, Issue 3 · 10 Sep 2016 · 7,133 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesigning of PID Controller for Discrete Time Linear System Using Balanced Approach Reduced Order ModelC.S. Ravichandran, S. Subha Rani, T. ManikandanModeling physical systems usually results in complex high-order dynamic models. It is often desirable to approximate these models by simpler models with reduced order. This study deals with the design of discrete time linear system using a balanced approach reduced order model. The reduced order model retains the desired state variable which contains a significant contribution. A PID controller is … …American Journal of Applied Sciences, Vol. 4, Issue 3 · 31 Mar 2007 · 7,132 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSolutions to Managing Drought and Reducing DemandsSaeid Eslamian, Saleh Tarkesh Esfahani, Kaveh Ostad-Ali-AskariConserving and saving water during droughts need a special attitude and great attention. Because according to a variety of studies conducted, nowadays our demand and need for water far exceed the amount of water resources available in different areas. As a result, in order to cope with this crisis, it is necessary to use water-recycling systems, reduce demands, employ optimal … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 29 Jul 2020 · 6,977 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordA Survey of Data Anonymization Techniques for Privacy-Preserving Mining in BigdataHelen Wilfred Raj, Santhi BalachandranBigdata era is seeing the data burst occurring in a multitude of angles that are better expressed in terms of the 4Vs (Volume, Velocity, Velocity, Veracity). While trying to infer information from data, care should be exercised as not to reveal the identity of the data owner, which breaches the privacy rights. Leakage of information can happen right from the … …Journal of Computer Science, Vol. 16, Issue 2 · 31 Dec 2019 · 8,066 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTRACKING THE POSITION OF MULTIPLE HUMAN GESTURES USING CONTOUR MAPPING ALGORITHMT. S. Arulananth, T. Jayasingh, S. RaviThis study relates to a method for determining the position variation (for example a moving object, facial gesture tracking) using markers. The movement is determined based on the periodic frames captured using a camera. The experimental results show that this algorithm can accurately segment human movements from complex background and can greatly reduce the computational workload with less storage memory, … …Journal of Computer Science, Vol. 10, Issue 10 · 22 May 2014 · 6,506 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordANALYSIS OF REDUCTION IN COMPLEXITY OF MULTIPLE INPUT- MULTIPLE OUTPUT-ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMS WITH CARRIER FREQUENCY OFFSET ESTIMATION AND CORRECTIONSabitha Gauni, Kumar RamamoorthyOrthogonal Frequency Division Multiplexing (OFDM) is a promising research area in Wireless Communication for high data rates. The Multiple Input-Multiple Output (MIMO) technology when incorporated with the OFDM system promise a significant boost in the performance. But, the MIMO-OFDM systems are very sensitive to Carrier Frequency Offset (CFO) as it deteriorates the system performance with the rise of Inter-Carrier-Interference (ICI). … …Journal of Computer Science, Vol. 10, Issue 2 · 13 Nov 2013 · 6,791 accessesView PDFCite
