Research ArticleOpen accessIn the abstractA Block Cipher Algorithm for Multimedia Content Protection with Random Substitution using Binary Tree TraversalP. Vidhya Saraswathi, M. VenkatesuluMany people consume multimedia content (images, music, movie) on portable devices like DVD player, MP3 player, Portable Multimedia Player and also through Internet. Problem statement: The conventional algorithms such as DES and AES cannot be used directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes and require real-time operations, such as displaying, cutting, copying, bit-rate conversion … …Journal of Computer Science, Vol. 8, Issue 9 · 15 Aug 2012 · 7,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnnual Concentration Report and Emission Sources Analysis of the Air Pollutants Measured by the Air Quality Monitoring StationP Khaenamkaew, S. Raksawong, K. Wongsorntam et al.Problem statement: Air Quality Monitoring (AQM) station at Kasetsart University, Si Racha Campus, Thailand, was routinely monitor the annual concentrations and analysis the emission sources of the air pollutants in the area since 2007. The level of concentration CO, SO2, NOx and O3 were measured. PM10 concentration was measured by mean of TOEM method. The PM10 and TSP (manifold) filters … …American Journal of Environmental Sciences, Vol. 7, Issue 5 · 1 Oct 2011 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval and Recovery of Lead from Aqueous Solution by Low Cost MediaLucia Pappalardo, Fawwaz Jumean, Naser AbdoProblem statement: To remove Pb(II) from wastewater using local UAE sand and then to recover the removed Pb(II). Approach: Removal efficiency of Pb(II) from wastewater was investigated using white, yellow and red United Arab Emirates sand with pore sizes < 300 μm. Two methods were employed: batch equilibrium and column filtration. In the batch equilibrium study, the effect of sand … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 6,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecurity Challenges in Multicast Communication for Mobile Ad Hoc NetworkS. Gunasekaran, K. DuraiswamyProblem statement: Multicasting communication network accepted a single message from an application and delivered copies of the message to multiple recipients at different locations. Recently, there has been an explosion of research literature on multicast communication environment. The objective of this study were to contribute the complexity of supporting current multicast applications, (i) the lack of reliable multicast transport mechanisms … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Cadmium, Copper, Lead and Nickel from Aqueous Solution by White, Yellow and Red United Arab Emirates SandL. Pappalardo, F. Jumean, N. AbdoProblem statement: To remove toxic heavy metal ions from wastewater using local sand as a low cost adsorbent. Approach: Removal efficiency of Cd(II), Cu(II), Pb(II) and Ni(II) from aqueous solution by white, yellow and red UAE sand was investigated at 25.0°C using the methods of batch equilibrium adsorption and column filtration. In each case, a mixture containing 20 ppm of … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Type of Network Security Protocol Using Hybrid Encryption in Virtual Private NetworkingE. Ramaraj, S. KarthikeyanToday wireless communications is acting as a major role in networks. Through year-end 2006, the employee's ability to install unmanaged access points will result is more than 50% of enterprises exposing sensitive information through the wireless virtual private networks (VPN). It enables you to send the data between two computers across a shared or public network in a manner that … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractKey Exchange Protocol in Elliptic Curve Cryptography with No Public PointK. Kaabneh, H. Al-BdourIn recent years some cryptographic algorithms have gained popularity due to properties that make them suitable for use in constrained environment like mobile information appliances, where computing resources and power availability are limited. One of these cryptosystems is Elliptic curve which requires less computational power, memory and communication bandwidth compared to other cryptosystem. This makes the elliptic curve cryptography to … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 7,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrometric Methods Used to Determine Heavy Metals and Total Cyanides in Accidental Polluted SoilsA. Mihaly-Cozmuta, L. Mihal Cozmuta, V. Viman et al.The study presents the level of soil pollution in the area adjacent to three sedimentation ponds as a result of an environmental accident. Soil samples from various sites have been collected and analyzed to determine the concentration of heavy metals (Cu, Pb, Zn) and total cyanides. The analysis methods used were ICP-AES for heavy metals and the colorimetric for total … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractAI-Driven Visual Communication Strategies for Enhancing Engagement in Smart Hospitality PlatformsYudhiet Fajar Dewantara, Yana Erlyana, Lim Jing YiThe rapid evolution of Smart Hospitality has reshaped how tourists interact with service providers. Visual communication plays a pivotal role in influencing engagement, yet most digital content remains generic, limiting brand resonance. This study investigates AI-driven visual communication strategies to enhance engagement by bridging computer science and design communication. A mixed-method approach was employed, starting with the analysis of 120 … …Journal of Computer Science, Vol. 22, Issue 9 · 7 Sep 2026 · 677 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiocontrol of Winter Wheat Root Rot by Rhizosphere Microorganisms in KazakhstanNurlan Kuldybayev, Amankeldy Sadanov, Aigerim Qairatova et al.Root rot remains one of the most significant diseases of winter wheat (Triticum aestivum L.) in Kazakhstan, resulting in substantial yield losses. This study aimed to isolate and identify rhizosphere microorganisms associated with winter wheat and evaluate their antagonistic activity against root rot pathogens in the Almaty region of Kazakhstan.
