Research ArticleOpen accessIn the keywordsAbsolute Measures of Interindividual Variation: A Simulation StudyJosé Moral-de la RubiaFour absolute measures and one relative measure of interindividual variability have been defined, together with their point and interval estimation (bootstrap and asymptotic), and an R script has been developed for their computation. However, further simulation studies are required to strengthen their methodological evaluation. This study focused on the three absolute measures with potentially better regularity conditions, Mean Interindividual Differences … …Journal of Mathematics and Statistics, Vol. 22, Issue 1 · 4 Aug 2026 · 957 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTree Volume Prediction Model of Cupressus lusitanica Species: in North-Western Highlands of EthiopiaYishak Adgo Kassie, Abebaw Alene YallewA significant basis of raw materials for the forest products industry is provided by Cupressus lusitanica, one of the commercial timber tree species found in the forest. Accurate tree and stand volume development models are necessary for intensive forest management to yield timber. The goal of this study was to develop and validate volume equations for Cupressus lusitanica tree species … …American Journal of Environmental Sciences, Vol. 21, Issue 1 · 26 Aug 2025 · 5,936 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSecure Symmetric Block Cipher Design for Encrypting the Bitcoin Wallets in Cryptocurrencies ApplicationsOmar A. Dawood, Othman I. Hammadi, Falath M. MohammedThis paper proposes a new symmetric secret-key cipher for construction of block cipher model. This new approach is considered as a smart step that can be applied to the long process research of modern designing methods used in developing earlier symmetric algorithms. The present cipher can encrypt block lengths of 128-bit by employing Substitution-Permutation Network (SPN) structure. The present cipher … …Journal of Computer Science, Vol. 15, Issue 5 · 1 Jun 2019 · 8,412 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImplementation Wireless Adapter Interface Module with Gateway Device for Connection to 4-20 mA TransmittersWaleed Ishaq Hameed, K. Ivica, Amar Al-jzari, Yasir I. AbdulraheemWireless communication is emerging technology from the office world to the industrial world. It is important that this technique are applied by the users in industrial environments because the industrial communication underlies stricter conditions than office communication. In this paper, It has been designed and implemented wireless adapter interface module with gateway connected to 4-20 mA devices and the Differential … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 1 Jul 2017 · 8,027 accessesView PDFCite

Research ArticleOpen accessIn the keywordsA New Algorithm for Fractal Coding Using Self Organizing MapS. Bhavani, k. ThanushkodiProblem statement: In medical imaging, lossy compression schemes are generally not used due to possible loss of useful clinical information and also degradations may result in lossy compression owing to operations like enhancement. As the medical images are huge in size a good lossy compression technology is required to store them in medical archives in an economical manner. There is … …Journal of Computer Science, Vol. 8, Issue 6 · 15 Mar 2012 · 7,583 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpulse Volt-Time Characteristics of Oil and OIP InsulationS. Venkatesan, S. UsaEstimation of insulation strength of transformer oil and Oil Impregnated Paper (OIP) insulation, which constitutes major portion of insulation in power transformer, is an important task. Also, it is often necessary to evaluate the breakdown strength of oil and OIP under non-standard impulse voltages, since the oil and OIP insulation is subjected to non-standard waveshapes between inter-disc and inter-turn insulation. … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,241 accessesView PDFCite
