Research ArticleOpen accessIn the keywordsImage Steganography by Mapping Pixels to LettersMohammed A.F. Al-HusainyProblem statement: Steganography hides the very existence of a message so that if successful it generally attracts no suspicion at all. Using steganography, information can be hidden in carriers such as images, audio files, text files, videos and data transmissions. In this study, we proposed a new framework of an image steganography system to hide a digital text of a … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 8,328 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGeochemistry of Sediment in the Major Estuarine Mangrove Forest of Terengganu Region, MalaysiaB.Y. Kamaruzzaman, M.C. Ong, M.S.Noor Azhar et al.Surface sediments collected from seven estuarine mangrove forests of Terengganu region (100 sampling points) were anaylzed for Pb, Cu and Zn using the sensitive Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The average concentration of Pb, Cu and Zn were 10.5±7.12 µg g-1 dry weights, 31.1±16.5 µg g-1 dry weights and 20.8±13.3 µg g-1 dry weights, respectively. The statistical analysis of … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,323 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPerformance Optimization of Discrete Wavelets Transform Based Image Watermarking Using Genetic AlgorithmsA. Al-Haj, A. Abu-ErrubThe excellent spatial localization, frequency spread and multi-resolution characteristics of the Discrete Wavelets Transform (DWT), which were similar to the theoretical models of the human visual system, facilitated the development of many imperceptible and robust DWT-based watermarking algorithms. There had been extremely few proposed algorithms on optimized DWT-based image watermarking that can simultaneously provide perceptual transparency and robustness since these … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,326 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAccess Weight Replica Consistency Protocol For Large Scale Data GridMohammed Radi, Ali Mamat, M. M. Deris et al.Replication is a well known technique to improve reliability and performance for a Data Grid. Keeping consistent content at all distributed replica is an important subject in Data Grid. Replica consistency protocol using classical propagation method called the radial method suffers from high overhead at the master replica site, while line method suffers from high delay time. In Data Grid … …Journal of Computer Science, Vol. 4, Issue 2 · 28 Feb 2008 · 7,301 accessesView PDFCite
Research ArticleOpen accessIn the keywordsIntellectual Property Rights Legislation and Computer Software Piracy in JordanSaleh A. SharariThis paper presents a serious worldwide problem, namely, computer software piracy and its impact on global economy, in general, and Jordanian economy, in particular. The paper also presents a detailed analysis of the Jordanian IPR legislation and Jordan's commitment to international and bilateral agreements with regards to this issue. Finally, the research proposes a number of recommendations on how Jordan … …Journal of Social Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,296 accessesView PDFCite
Research ArticleOpen accessIn the author namesGeomagnetic Anomalies: LineamentsGiovanni Pietro Gregori, Bruce Allen Leybourne, Ugo Coppa, Giuseppe LuongoGeomagnetic anomaly maps can be interpreted according to either (i) To the electromagnetic (e.m.) Induction by the solar wind that generates telluric currents aimed to oppose the geomagnetic field originated by the deep geomagnetic dynamo, or (ii) By stray currents that outflow from the deep Earth’s circuitry. The results correlate with other morphological, geodynamic, and tectonic features, which represent a … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 2 Jan 2025 · 4,824 accessesView PDFCite
Review ArticleOpen accessIn the abstractTEC-Driven Mini Refrigerators: Recent Applications With Performance CharacteristicsTamer Guclu, Pinar Mert Cuce et al.Thermoelectric Cooling (TEC) technology has become a remarkable alternative in mini refrigerator applications in recent years, thanks to its lack of moving parts, silent operation, compact structure and environmentally friendly features. This study aims to examine the current usage areas, performance characteristics, and engineering challenges of TEC systems in mini refrigerator applications with a holistic approach. Experimental and theoretical studies … …Energy Research Journal, Vol. 14, Issue 1 · 23 Dec 2025 · 3,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganic Fertilizers: An Agroecological and Commercial Bet On Smallholders in the Sumapaz RegionElizabeth Ann Escobar Cazal, Taha Ahmadi, Diego Fabián Bejarano Morales et al.The feasibility of an agroecological project is supported, among other factors, by the cost-benefit relationship, which tends to shift profitability paradigms on organic fertilizers within the context of long-term finances. For this purpose, the objective of this paper is to carry out a financial study to market organic fertilizers (compost and vermicompost) in the Sumapaz region. An initial analysis of … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 29 Jul 2020 · 6,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Exhaust Gas Temperature on the Performance of Automobile Adsorption Air-ConditionerAbdul Hadi N. Khalifa, Ali H. Jabbar, Jamal A. MuhsinAn adsorption air conditioning unit of two beds was designed and built. Each bed was constructed from two concentric copper pipes sets, the length of the pipes in each set was 1500 mm pipe. The inner pipe was 50 mm in diameter while the outer pipe was of 100 mm diameter. The inside surface of the outer pipe and the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 13 Oct 2015 · 8,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATIONS ON THE PERFORMANCE OF VAPOUR COMPRESSION SYSTEM RETROFITTED WITH ZEOTROPIC REFRIGERANT R404AA. Lovelin Jerald, D. SenthilKumaranThe environmental impacts like global warming and ozone depletion has become a challenge to the refrigeration and air conditioning industry. Chloro Fluoro Carbons (CFCs) and Hydro Flouro Carbons (HCFCs) are referred to as an Ozone Depleting Substances (ODS) because once these gases are released into the environment and reach the stratosphere, depletes the ozone layer. This research paper aims to … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 11 Feb 2014 · 7,630 accessesView PDFCite
