Review ArticleOpen accessIn the author namesReview on Main Active Substances and Functions in Jasminum Sambac (L.) AitonJiaqi Jian, Keying Han, Qiwei Guo et al.This article reviewed the relevant literature on the main active substances and functions of jasmine (Jasminum sambac (L.) Aiton). The results showed that: 1. The main active substances in jasmine are volatile oil, polysaccharides, and flavonoids. Volatile oil is a mixture of large molecules; Polysaccharide is a type of heteropolysaccharide or sugar complex; Flavonoids mostly exist in the form of … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 18 Sep 2023 · 7,159 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIntelligent Digital Signal Modulation Recognition using Machine LearningMudhafar Haji Mala Abd, Sadegh AminifarInrecent years, modulation type recognition has received a lot of attentionacross the board. There are several methods to detect modulation types, butthere are only a few effective methods to handle signals with a higher level ofnoise. This study introduces an approach to verify the ability of differentmachine learning algorithms to automatically manage noise in detecting digitalmodulations. This research examines two … …Journal of Computer Science, Vol. 18, Issue 10 · 26 Sep 2022 · 6,098 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRecognition of Hand Printed Characters Based on Simple Geometric FeaturesSami M. Halawani, Ibrahim A. AlbidewiProblem statement: The use of computers in information processing technology nowadays is one of the main trends of office automation. For more than four decades, information from the outside world is transferred into computers in a traditional way by keying in these raw data with the help of keyboard. Most of these data are in hand printed form and very … …Journal of Computer Science, Vol. 6, Issue 12 · 30 Nov 2010 · 7,133 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGroup Re-keying Protocol Based on Modular Polynomial Arithmetic Over Galois Field GF(2n)Sundaram Sudha, Azman Samsudin, Mohammad Ahmad AliaProblem statement: In this study we propose a group re-keying protocol based on modular polynomial arithmetic over Galois Field GF(2n). Common secure group communications requires encryption/decryption for group re-keying process, especially when a group member is leaving the group. Approach: This study proposes secret keys multiplication protocol based on modular polynomial arithmetic (SKMP), which eliminates the need for the encryption/decryption … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,171 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImplementation of a Novel Concatenated FEC by RS and Irregular Turbo Codes on OFDM SystemsA. Shanmugam, A. R. Abdul Rajak, S. Vishwanath, R. UpendraCode Division Multiple Access (CDMA) performs well in a multi-cellular environment where a single frequency is used in all cells. Code Division Multiple Access (CDMA) has severe problems associated with multipath and Channel news. One possible problem is that the receiver may require a very large dynamic range in order to handle the large signal strength variation among users. Due … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,042 accessesView PDF Cite
