Research ArticleOpen accessIn the abstractTracking Algorithm for Estimating the Orientation Angles of the Object Based on the Signals of Satellite Radio Navigation SystemAlexandr PerovIn the article, the theory of optimal filtering of information processes is used to synthesize optimal one-stage estimation algorithm for the object orientation angles using the signals of the satellite navigation system. The article also provides equations of optimal filtering, as well as their representation in the form of the tracking system comprising of an orientation angles discriminator and a … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 7 Dec 2015 · 6,474 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel Prefix Tri-Literal Word Analyser: Rule-Based ApproachMohammed M. Abu Shquier, Khaled M. AlhawitiArabic stemming is a technique to find the stem or lexical root for Arabic words through the process of eliminating affixes (preffixes, infixes and suffixes) attached to their roots. Several approaches have been implemented to generate the stem of Arabic words according to a certain level of analysis, i.e., root-based approach, stem-based approach and statistical approach. Arabic language is a … …Journal of Computer Science, Vol. 11, Issue 4 · 27 Jun 2015 · 6,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractARABIC PART OF SPEECH TAGGING USING K-NEAREST NEIGHBOUR AND NAIVE BAYES CLASSIFIERS COMBINATIONRund Mahafdah, Nazlia Omar, Omaia Al-OmariPart Of Speech (POS) tagging forms the important preprocessing step in many of the natural language processing applications such as text summarization, question answering and information retrieval system. It is the process of classifying every word in a given context to its appropriate part of speech. Different POS tagging techniques in the literature have been developed and experimented. Currently, it … …Journal of Computer Science, Vol. 10, Issue 9 · 2 May 2014 · 7,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractHYBRID FEATURE SELECTION ALGORITHM FOR INTRUSION DETECTION SYSTEMSeyed Reza Hasani, Zulaiha Ali Othman, Seyed Mostafa Mousavi KahakiNetwork security is a serious global concern. Usefulness Intrusion Detection Systems (IDS) are increasing incredibly in Information Security research using Soft computing techniques. In the previous researches having irrelevant and redundant features are recognized causes of increasing the processing speed of evaluating the known intrusive patterns. In addition, an efficient feature selection method eliminates dimension of data and reduce redundancy … …Journal of Computer Science, Vol. 10, Issue 6 · 31 Jan 2014 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractPesticide use in South and South-East Asia: Environmental Public Health and Legal ConcernsAbhik GuptaProblem statement: The South and South East Asian countries are characterized by their rich biodiversity as well as cultural diversity. Agricultural expansion for livelihood security is leading to an increase in pesticide application in this region. It has been observed that because of the hot and humid conditions prevalent in this region, most farmers and pesticide applicators do not use … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 12 Mar 2012 · 8,551 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Method for Contrast Enhancement in Still Images using Histogram Modification FrameworkC. G. Ravichandran, V. MagudeeswaranProblem statement: Image enhancement improves an image appearance by increasing dominance of some features or by decreasing ambiguity between different regions of the image. Histogram based image enhancement technique is mainly based on equalizing the histogram of the image and increasing the dynamic range corresponding to the image. Approach: Histogram Equalization is widely used in different ways to perform contrast … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 8,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Novel Artificial Neural Network Based Stock Market Forecasting System on Field-Programmable Gate ArraysMd. Syedul Amin, Md. Mamun, Fazida Hanim Hashim et al.Problem statement: Multiagent system is very proficient and has rules well-suited for financial forecast with its neural network. In financial forecasting, the approach for rules extractions is less pertinent and involves algorithms which are complex. The unsupervised network method lacks in comprehensibility and leads to ambiguity. Approach: The application of neural network technology to real-time processing of financial market analysis … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 12 Sep 2011 · 7,627 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultilevel Classifier in Recognition of Handwritten Arabic CharactersRawan Ismail Zaghloul, Enas Faisal AlRawashdeh, Dojanah Mohammad Kadri BaderProblem statement: Arabic offline handwriting recognition is considered one of the most challenging topics. This is probably caused by the fact that Arabic recognition system faced many problems during the development stage. It faces the usual problems of character recognition in general, in addition to the problems that are specific to Arabic language only.
