Research ArticleOpen accessEvery word in the titleSuccessive Image Interpolation Using Lifting Scheme ApproachRohini S. Asamwar, Kishor Bhurchandi, A. S. GandhiProblem statement: Fast and accurate interpolation and resizing of images and video frames is a much sought after research area in multimedia applications. The more accurate schemes are computationally expensive and require more time for execution. We proposed here Discrete Wavelet Transform (DWT) using lifting scheme as an accurate and computationally inexpensive interpolation technique for image resizing. Approach: In this … …Journal of Computer Science, Vol. 6, Issue 9 · 30 Sep 2010 · 7,573 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Policy-Based Admission Control Scheme for Voice over IP NetworksSami Alwakeel, Agung PrasetijoProblem statement: In Voice Over IP (VOIP) network, when more calls are admitted to the network, more voice packet traffic is created. Since bandwidth is always limited, this may result network congestion and/or may affect voice quality. Thus, we needed a mechanism for improving the Quality of Service (QoS) by controlling VOIP calls admission. Approach: Given a specified bandwidth and … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,609 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Digital Signature Scheme Based on Mandelbrot and Julia Fractal SetsMohammad Ahmad Alia, Azman Bin SamsudinThis paper describes a new cryptographic digital signature scheme based on Mandelbrot and Julia fractal sets. Having fractal based digital signature scheme is possible due to the strong connection between the Mandelbrot and Julia fractal sets. The link between the two fractal sets used for the conversion of the private key to the public key. Mandelbrot fractal function takes the … …American Journal of Applied Sciences, Vol. 4, Issue 11 · 30 Nov 2007 · 6,962 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Different Text Attack Algorithm in Integer Factoring Based SchemesMohammed A. AL-Fayoumi, Sattar J. Aboud, Musbah M. AqelText attack in integer factoring based schemes is generally calculated as an intrinsic characteristic of its symmetric attack. In this article, we illustrate that asymmetric integer factoring based schemes are also vulnerable to a text attack. Also, we show that a single message is required to increase a successful text attack versus the Lucas scheme. …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,654 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRedundancy Schemes for High Availability Computer ClustersChristian K. Bassek, Samuel Pierre, Alejandro QuinteroThe primary goal of computer clusters is to improve computing performances by taking advantage of the parallelism they intrinsically provide. Moreover, their use of redundant hardware components enables them to offer high availability services. In this paper, we present an analytical model for analyzing redundancy schemes and their impact on the cluster’s overall performance. Furthermore, several cluster redundancy techniques are … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 7,229 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDesign of New Load Shedding Special Protection Schemes for a Double Area Power SystemH. Seyedi, M. Sanaye-PasandIn this paper several Under Frequency Load Shedding (UFLS) schemes are designed as special protection schemes to preserve the integrity of islands, formed following the outage of tie lines connecting two areas in a double area power system. For the purpose of analysis, the Iranian interconnected grid is simulated in a suitable power system analysis software. The grid is connected … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,572 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Various Schemes of Feeding Calves with Whole Milk on their Growth Indicators and Physiological StateK. K. Akhazhanov, T. K. Bekseitov, J. J. Uakhitov et al.In dairy farming, special requirements are imposed on the feeding of replacement young animals. The period when young animals receive colostrum and milk is considered important for raising viable and productive animals. During this time, a large amount of whole milk is consumed by calves. In this connection, the purpose of our study was to compare the effect of various … …American Journal of Animal and Veterinary Sciences, Vol. 18, Issue 3 · 16 Aug 2023 · 5,361 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEstimation for Unknown Parameters of the Burr Type-XII Distribution Based on an Adaptive Progressive Type-II Censoring SchemeMontaser M. AmeinIn this study, the Maximum Likelihood Estimation (MLE) and Bayes estimation are exploited to make interval estimation based on adaptive progressive Type-II censoring for the Burr Type-XII distribution. Explicit form for the parameters of Bayes estimator doesn’t exist, so, Markov Chain Monte Carlo (MCMC) method is used as approximation to find posterior mean under squared error loss function. Real data … …Journal of Mathematics and Statistics, Vol. 12, Issue 2 · 29 Apr 2016 · 7,306 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBurden of Early Pregnancy and Reach of Cash Incentive Scheme for Promoting Institutional Delivery in IndiaAnjali Srivastava, Priyanka Ribhu, Purujit PraharajThe burdenof early pregnancy and high out-of-pocket costs necessitate the use ofinstitutional care, qualified medical staff, and financial incentives to boostthe quality of maternal health services. In response, the Indian governmentintroduced the Janani Suraksha Yojana (JSY) scheme in2005, which offers cashtransfers to underprivileged women using public health facilities for childdelivery. Using the data from the National Family Health Survey-5 and … …Journal of Social Sciences, Vol. 21, Issue 1 · 5 Jun 2025 · 6,906 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Nested Digital Watermarking Scheme Using GARN with DWTEdward Yellakour Baagyere, Peter Awonnatemi Agbedemnab, Mohammed Akolgo, Strato Angsoteng BayitaaCopyright infringement is undoubtedly one of the major challenges in the film and TV industries over the years but has become even more pervasive lately as a result of technological advancement. This has made it possible to decode hitherto, hard-encoded, or encrypted multimedia content resulting in a lot of losses to companies in such industries.
