Research ArticleOpen accessEvery word in the titleApplication Specific Integrated Circuits Design and Implementation of Rademacher and Walsh FunctionsA. Abbasi, A. R.M. Alamoud, S. A. AbbasiThe orthogonal functions, specially the Rademacher and Walsh functions are being increasingly used in Digital Signal Processing (DSP). Today’s DSP applications require fast processing time in order to meet the challenges of the real time systems. State-of-the-art implementation technologies are therefore being used. This study describes the design and implementation of Rademacher and Walsh functions targeted to the state-of-the-art Cell … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 4 · 7 Jan 2014 · 7,340 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCan Grammar Define Similarity of Human Natural Languages?Vladimir Nikolaevich Polyakov, Ivan Sergeevich Anisimov, Elena Andreevna MakarovaThe aim of the present study is to show that similarity of human natural languages can be conveyed not only by phonetic data, but also by grammar. The paper regards the largest typological database WALS and its possibilities in the sphere of genealogic relationship of languages. Using the method of two-objective optimization and data mining, which is new for linguistic … …American Journal of Applied Sciences, Vol. 13, Issue 10 · 5 Oct 2016 · 7,286 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGeneralization of Boolean Functions Properties to Functions Defined over GF(p)Saad Elmansori, B. E. EsamProblem statement: Traditionally, cryptographic applications designed on hardware have always tried to take advantage of the simplicity of implementation functions over GF(p), p = 2, to reduce costs and improve performance. On the contrast, functions defined over GF(p); p > 2, possess far better cryptographic properties than GF(2) functions. Approach: We generalize some of the previous results on cryptographic Boolean … …Journal of Computer Science, Vol. 8, Issue 6 · 13 Mar 2012 · 7,436 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVHDL Modeling, Simulation and Prototyping of a Novel Arbitrary Signal Generation SystemS. A. Abbasi, A. R.M. Alamoud, J.M. Al ShahraniProblem statement: Arbitrary signal generators play an important role in many applications. Several different techniques utilizing both analog and digital approaches are being used for the generation of periodic signals. However, all of them suffer from many drawbacks. In this study, we present modeling, simulation and prototyping of a novel periodic arbitrary signal generation system using FPGAs. The proposed system … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 7,755 accessesView PDFCite
Research ArticleOpen accessIn the author namesProduction of Xylitol from Agricultural Waste by Enzymatic MethodsMarie K. Walsh, Hussein Fadhil Khliaf, Khalida A. ShakirEnzyme catalyzed production of xylose from autoclaved and non-autoclaved wheat straw was conducted followed by bioconversion of xylose to xylitol using a Crude preparation of Xylose Reductase (CXR) from Candida guillermondii. Ground wheat straw (autoclaved and non autoclaved) was treated at 40 and 50°C for up to 9 h at pH 4.5 with various concentrations of xylanase (12.4 to 37.2 … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 26 Mar 2018 · 9,655 accessesView PDFCite
Research ArticleOpen accessIn the author namesReview Article; Duodeno-Gastro-Esophageal Reflux Combined and IsolatedAyman Osman Nasr, William Robb, Thomas Neil WalshBarrett’s esophagus is the chief risk factor for esophageal adenocarcinoma. Reflux of gastric acid has long been related to the development of esophagitis and Barrett’s esophagus, but the role of duodenal contents is controversial. We review the literature on the role of duodenal contents in the development of esophagitis, Barrett’s esophagus and adenocarcinoma in addition to the role of acid … …Current Research in Medicine, Vol. 4, Issue 1 · 8 May 2013 · 7,825 accessesView PDFCite
