Research ArticleOpen accessIn the abstractQuery Based Client Indexing in Client/Server Information SystemsHagen HöpfnerOne issue in client/server information systems is the storage of the relationships between clients and data used by these clients. In particular in scenarios that allow the caching of data on the client site, this information can be used in order to keep the global database consistent. Thus, if the data on the server are updated, it is possible to … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,895 accessesView PDFCite
Research ArticleOpen accessIn the abstractDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,183 accessesView PDFCite
Research ArticleOpen accessIn the abstractMaximally Distant Codes Allocation Using Chemical Reaction Optimization and Ant Colony Optimization AlgorithmsTaisir Eldos, Waleed Nazih, Aws KananError correcting codes, also known as error controlling codes, are set of codes with redundancy that allows detecting errors. This is quite useful in transmitting data over a noisy channel or when retrieving data from a storage with possible physical defects. The idea is to use a set of code words that are maximally distant from each other, hence reducing … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluating Nursing and Midwifery Metrics: Providing Evidence to Support Change and Renewal in Healthcare Services in IrelandRandal Parlour, Paul Slater, Elizabeth BreslinThis study was commissioned by senior nursing and midwifery management to evaluate the impact of 'medication management metrics' (Medication Storage and Custody and Medication Administration) upon the delivery of nursing and midwifery care in the Health Service Executive (HSE) North West Area. The study employed a mixed-methodology using both quantitative and qualitative approaches to data collection and analysis. Methodological and … …International Journal of Research in Nursing, Vol. 6, Issue 1 · 10 Jul 2015 · 7,130 accessesView PDFCite

Research ArticleOpen accessIn the abstractHybrid Broadcast Group Management Protocol for Secure, Scalable and Efficient Group CommunicationM. Sayee Kumar, T. PurusothamanIn hasty growth of communication, security plays a central role in maintaining confidentiality of data in group communication. Keeping the data intended for the group in confidential manner is the most important security feature need to be sustained for the group communication. An efficient group key management mechanism named as Hybrid Broadcast Group Management Protocol (HBGMP) is devised based on … …Journal of Computer Science, Vol. 11, Issue 2 · 17 Sep 2014 · 7,060 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Star Topology based Multicast Key Management AlgorithmK. Saravanan, T. PurusothamanProblem statement: Secure group communication is very important for many applications such as internet pay sites. It provides efficient delivery of identical data to only the customers in the group. In large and dynamic multicast groups, the group keys of members have to be changed frequently whenever the member leaves or joins. A common method is to apply a symmetric … …Journal of Computer Science, Vol. 8, Issue 6 · 22 Mar 2012 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractMedical Image Compression with Lossless Region of Interest Using Adaptive Active ContourR. Loganathan, Y. S. KumaraswamyProblem statement: With increasing bandwidth, digital medical image storage and transmission is a boon to patients and health professionals alike. Medical images are available instantly and avoid the need to carry the data physically. Popular imaging techniques extensively used in medicine include X-Ray, Magnetic Resonance Imaging (MRI), Ultrasound and Computed Tomography (CT). The images produced from the above techniques can … …Journal of Computer Science, Vol. 8, Issue 5 · 1 Mar 2012 · 7,727 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Signal Detection of Sensor Array Units Using 5-3-1 Rule Based Matched Filter Algorithm with Intelligent IdentifiersMahmoud Z. IskandaraniA novel approach to signal detection and identification was developed and tested. The new algorithm was based on provision of tagging a Matched Filter (MF) with identifiers to recognize the source signal with and without noise, so that classification can be carried out. The algorithm was applied successfully to chemical Sensor Array Units (SAU). Problem statement: Signals obtained from chemical … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,846 accessesView PDFCite
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
