Research ArticleOpen accessEvery word in the titleCONSTRUCTION OF GENERAL SUBSUMPTIVE SOLUTIONS OF BOOLEAN EQUATIONS VIA COMPLETE-SUM DERIVATIONAli Muhammad Ali Rushdi, Hussain Mobarak AlbarakatiBoolean-equation solving permeates many diverse areas of modern science. To solve a system of Boolean equations, one usually combines them into an equivalent single Boolean equation {f(X) = 0} whose set of solutions is exactly the same as that of the original system of equations. One of the general classes of solutions for Boolean equations is the subsumptive general solution, … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 13 Mar 2014 · 7,112 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOR-Bridging Fault Identification and Diagnosis for Exclusive-OR Sum of Products Reed-Muller Canonical CircuitsV. Geetha, N. Devarajan, P. N. NeelakantanProblem statement: The faults in digital circuit can be classified broadly as single stuck-atfaults, multiple stuck-ay-faults, stuck-open faults, stuck-on faults, path delay faults, transient faults. Extensive research had been carried out in the field of testing of digital circuits to limit the number of input vectors. The cardinality of the test vectors proposed by many authors was quite high for … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,156 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRandom Sum of Mixtures of Sum of Bivariate Exponential DistributionsAbd El-Moneim A.M. Teamah, Ahmed M.T. Abd El-BarProblem statement: The distributions of R = X+Y and W = X/(X+Y), where X and Y follow Lawrance and Lewis`s bivariate exponential distribution, is generalized. Approach: In this research we found mixtures of sum of bivariate exponential random variables. Results: Also we calculated the probability density function (pdf) of the random sum of mixtures of sum of bivariate exponential random … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,321 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSingle Stuck-At Fault Diagnosing Circuit of Reed-Muller Canonical Exclusive-Or Sum of Product Boolean ExpressionsP. N. Neelakantan, A. E. JeyakumarA testable design with a universal test set for single stuck-at zero and stuck-at one faults of Reed-Muller canonical form of Exclusive-OR sum of product logic expressions is proposed. The test circuit detects almost all the single stuck-at faults and needs only simple modifications for variations in the circuit under test. The number of test vectors is also quite small … …Journal of Computer Science, Vol. 2, Issue 7 · 31 Jul 2006 · 6,593 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Approach for Developing Uncertain Multi-perspective Expert System Using the Algebraic Sum MethodMusbah J. AqelA multi-perspective expert system approach based on algebraic sum method was developed to deal with uncertain knowledge and provides different perspectives for different experts while dealing with single knowledge base according to experts' interests. However, assertion value for each perspective is calculated and by using the algebraic summation method a conclusion can be determined. …American Journal of Applied Sciences, Vol. 3, Issue 2 · 28 Feb 2006 · 6,739 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCHARACTERIZATION OF MARKOV-BERNOULLI GEOMETRIC DISTRIBUTION RELATED TO RANDOM SUMSMohamed Gharib, Mahmoud M. Ramadan, Khaled A.H. Al-AjmiThe Markov-Bernoulli geometric distribution is obtained when a generalization, as a Markov process, of the independent Bernoulli sequence of random variables is introduced by considering the success probability changes with respect to the Markov chain. The resulting model is called the Markov- Bernoulli model and it has a wide variety of application fields. In this study, some characterizations are given … …Journal of Mathematics and Statistics, Vol. 10, Issue 2 · 31 Mar 2014 · 6,711 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAbstractive Summarization of Long Educational Transcripts in the Era of GenAIDeepa Fernandes, Rupali Sunil WaghThe surge in online video data presents the imperative requirement of summarizing it for information compression, efficient understanding, and to support decision-making. Recent research studies have predominantly utilized structured input data for summarization. This paper explores the current state-of-the-art models in summarizing unstructured, conversational, and long transcript data. We further apply a transfer learning approach using a fine-tuned BART model, … …Journal of Computer Science, Vol. 22, Issue 8 · 7 Sep 2026 · 413 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiodiversity and Spatial Distribution of Hornbills in Pondok Buluh Educational Forest, North Sumatra, IndonesiaBudi Utomo, Nabillah Saraswita, Cindy Siahaan et al.Hornbills are large birds, several species of which are protected under national and international conservation legislation and face significant extinction risk. This study was conducted in the Specific Purposes Pondok Buluh Forest Area, North Sumatra, Indonesia, with the aim of identifying hornbill species present, estimating their population density, and characterizing their habitat. Hornbill surveys were carried out using the point … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 28 Mar 2026 · 1,408 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBioactivity of Sumac (Rhus Coriaria) Extract as a Green Alternative for Plant Pathogen InhibitionMohammed H. Al-Mamoori, Meisam Zargar, Elena N. Pakina, Fatih DadaşoğluEnvironmental stress caused by pathogenic fungi leads to considerable losses in global crop productivity. Plant-derived extracts are eco-friendly and sustainable alternatives that can inhibit biotic stresses. Sumac (Rhus coriaria) is widely used in industrial and medicinal applications due to its extract rich in secondary metabolites, similar to those found in chemical pesticides and pharmaceuticals. This study aimed to characterize the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 25 Nov 2025 · 2,211 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleScreening of Blast Resistance Genes from South Tapanuli Rice Cultivars, North Sumatra, IndonesiaSaleha Hannum, Hesti Wahyuningsih, Riyanto Sinaga et al.Rice blast disease caused by a phytopathogenic fungus, Magnaporthe oryzae, has been considered as a major threat to global rice productivity, including Indonesia. South Tapanuli is a regency in North Sumatra, known for its intensive and significant rice production activities.
