Research ArticleOpen accessIn the abstractArabic Text Steganography Using Unicode of Non-Joined to Right Side LettersAtef A. ObeidatSteganography is a technique for hiding data in media in a way that makes its existence hard to detect. Text files are a preferable format for use in steganography due to the small storage size of such files. This paper presents an Arabic text steganographic algorithm based on Unicode. The algorithm imposes a minimal change on connected letters without any … …Journal of Computer Science, Vol. 13, Issue 6 · 24 Jun 2017 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Breeding Qualities of Kazakh White-Headed Bulls by Testing Their ProductivityAruzhan Nugmanova, Aliya Akhmetaliyeva, Yedige Nassambayev et al.The purpose of the study was to quantify the breeding qualities of Kazakh White-Headed bulls by assessing their productivity metrics. The primary objectives were to analyze live weight dynamics, daily growth rates, feed conversion efficiency, and morphological meat quality and to employ "A" complex indices for evaluating the breeding potential. The study observed bulls aged 8-15 months at the Khafiza … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 26 Jul 2024 · 5,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Seaweed Extracts on Rice Growth and Tolerance to Salinity, Drought and Blast (Magnaporthe oryzae)Mir Sayeada Alam, Jannatun Nayeema, S. M. Rafiquzzaman, Motaher HossainRice, a primary staple, confronts a multitude of biotic and abiotic stresses. Drought and salinity, exacerbated by climate change and blast disease caused by Magnaporthe oryzae, significantly contribute to yield losses. To tackle the problems, two types of seaweeds-one known as Hypnea musciformis and another unknown-were collected from Saint Martin, Cox's Bazar, Bangladesh and then examined for the potential of … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 31 May 2024 · 6,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing Regression Analysis to Predict the Demand Function of Electricity: A Case StudyHasan Karimian Khozani, Esmaeil Esmaeili, Mohammad Najjartabar Bisheh et al.Due to the growing electricity consumption in Iran, investigating the changes of the electricity demand is one of the fundamental challenges facing many professionals and planners. The planners always invest efforts to address this issue by accurately predicting the electricity demand over the years and increasing the extra capacity respectively. One of the main tools for predicting the electricity demand … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 20 Dec 2020 · 6,462 accessesView PDFCite
Research ArticleOpen accessIn the abstractREDUCING TRANSMITTED POWER OF MOVING RELAY NODE IN LONG-TERM EVOLUTION-ADVANCED CELLULAR NETWORKSJaafar A. Aldhaibani, A. Yahya, R. B. Ahmad et al.Wireless multi-hop relay networks have become very significant technologies in mobile communications. These networks ensure data rate transfer and coverage extension with a low cost. In this study two types of relay are studied; Fixed Relay Node (FRN) and Moving Relay Node (MRN). Where system analyses for uplink and downlink transmission are derived in this study. Moreover the optimal relay … …Journal of Computer Science, Vol. 10, Issue 6 · 3 Feb 2014 · 6,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractPeak-to-Average Power Ratio Reduction Using Active Constellation Extension-Projection Onto Convex Sets Combined with Particle Swarm Optimization Added to Space Time Bloc Coding in Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing SystemAhmed Ouqour, Abdelhamid Louliej, Younes Jabrane et al.When generated Orthogonal Frequency Division Multiplexing (OFDM) signal is transmitted through a number of antennas in order to achieve diversity or cap any gain (higher transmission rate) then it is known as Multiple Input Multiple Output (MIMO)-OFDM. The full form of MIMO is multi input and multi output where signals are transmitted via multiple antennas instead of only one antenna … …Journal of Computer Science, Vol. 8, Issue 12 · 12 Dec 2012 · 6,995 accessesView PDFCite

Research ArticleOpen accessIn the abstractRe-quantization Codebook Using FingerprintZ. F. Muhsen, M. A. Dababna, A. A. NsourRe-quantization is a key technology for reducing the bit rate of compressed data. The reduction of the bit rate and in certain cases may result in signal quality degradation. Techniques need to be deployed to enhance the signal quality based on optimization techniques. The proposed scheme constructed an optimal re-quantization codebook in an iterative manner for a given original quantization … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractSupercritical Fluid Extraction of Palm CarotenoidsPuah C. Wei, Choo Y. May, Ma A. Ngan, Chuah C. HockThe extraction of carotenoids from crude palm oil was carried out in a dynamic (flow- through) supercritical fluid extraction system. The carotenoids obtained were quantified using off-line UV-visible spectrophotometry. The effects of operating pressure and temperature, flow rate of the supercritical carbon dioxide (SC-CO2), sample size of feed used on the solubility of palm carotenoids were investigated. The results showed … …American Journal of Environmental Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,768 accessesView PDFCite
