Research ArticleOpen accessIn the abstractMathematical Analysis of M/M/C Vacation Queueing Model with a Waiting Server and Impatient CustomersGanesh Sapkota, R. P. GhimireIn this study, the transient analysis of the M/M/C queueing system has been made under the provision of servers' single vacation and loss of impatient customers. Customers arrive in the system in the Poisson process and are served by multiple servers in an exponential distribution process. Customers are served in the chronological order of their arrival. The main purpose of … …Journal of Mathematics and Statistics, Vol. 18, Issue 1 · 19 Apr 2022 · 7,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhonocardiogram Classification Based on Machine Learning with Multiple Sound FeaturesKhalid M.O. Nahar, Obaida M. Al-Hazaimeh, Ashraf Abu-Ein, Nasr GharaibehIn this study the heartbeat sound signals were tackled by classifying them into heart disease categories such as normal, artifact, murmur and extrahals in an attempt for early detection of heart defects. Phonocardiogram (i.e., PCG) is used to obtain the digital recording dataset of the heart sounds using an electronic stethoscope or mobile device. Multiple features are extracted from the … …Journal of Computer Science, Vol. 16, Issue 11 · 26 Nov 2020 · 8,259 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Control Strategy for Parallel Fan-Powered VAV SystemsNabil Nassif, Iffat Ridwana, Mostafa Tahmasebi, Pejman EbrahimiASHRAE Guideline 36 recommends resetting the Supply Air Temperature (SAT) for Variable Air Volume (VAV) systems to balance fan power, heating and cooling loads and zone reheat requirements. This is achieved by employing a trim and response algorithm in conjunction with using the outside air temperature and readings from zone cooling loops. However, resetting the SAT for the VAV systems … …Energy Research Journal, Vol. 13, Issue 1 · 6 Jun 2022 · 10,353 accessesView PDFCite
Research ArticleOpen accessIn the abstractBacterial Diversity Change after Soil Fumigation and its Effect on the Population of Root-Knot NematodeMin Shan, Lihong Liu, Jing Chen et al.In order to explore the effects of soil fumigation on its bacterial diversity and root-knot nematode populations, the greenhouse tomato soil with root-knot nematode disease was fumigated during the summer idle period. This experiment used the high-efficiency organic sulfur soil fumigation treatment "Wofengkang"300 kg/hm2 to fumigate on the greenhouse tomato soil with a root-knot nematode incidence rate of 64.37% and … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 1 · 2 Mar 2022 · 5,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractUncertainty-Aware Ensemble Models for Improved Defect Detection in Noisy DataMadhavi Perla, Gadi Lava Raju, A Radha Krishna et al.Software defect prediction plays a crucial role in ensuring software quality and reliability, especially as modern systems become more complex and data rich. This study introduces an uncertainty-aware ensemble learning framework aimed at improving defect classification performance in noisy and imbalanced datasets, particularly those from the PROMISE and NASA KC1 repositories. The proposed model integrates multiple classifiers in a multi-learner … …Journal of Computer Science, Vol. 22, Issue 4 · 27 Apr 2026 · 1,542 accessesView PDFCite
Review ArticleOpen accessIn the abstractVisualization of Data Mining Techniques for the Prediction of Breast Cancer with High Accuracy RatesVasudev Sharma, Raj Kumar Rajasekaran, Shreya BadhrinarayananBreast cancer is one of the leading causes of death in women worldwide. Around one in 30 women are affected by breast cancer. Mammography has helped in detecting breast cancer in the early stages which have reduced mortality. The diagnosis of breast cancer is dependent on a variety of parameters. In this paper, we aim to create the best model … …Journal of Computer Science, Vol. 15, Issue 1 · 21 Jan 2019 · 8,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Trichoderma viride Cellulase Enzyme Concentration on Saccharification of Waste Paper MaterialsKhomotso M. P. Mokatse, M. Alfred Mogale, J. Pieter H. Van WykEnzymatic hydrolysis of lignocellulosic materials is one of the major steps in the commercialization process of converting cellulosic substrates into bio-products. The saccharification of lignocellulosic materials is usually achieved by a synergistic action of an enzyme mixture consisting of multiple cellulase enzymes such as endo-and exo-glucanase, cellobiohydrolase and β-glucosidase with different mode of actions. During the enzymatic hydrolysis of the … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 28 Oct 2021 · 6,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiodegradation of Low-Density Polyethylene Film by UV Irradiated and Non-Irradiated Pseudomonas Aeruginosa D5Olusola Adeoye Oluwole, Temitayo Omotunde Olowomofe, Ikeoluwa Gloria OlaniyanLow-density polyethylene (LDPE) constitutes 60% of total plastic production, and non-degradable polyethylene carry bags are the most common type of solid waste found. Their recalcitrance in the environment is thus a major concern for environmentalists. This study investigated the potential of Ultraviolet (UV) induced mutation in enhancing biodegradation of LDPE films by two diesel degrading bacteria, Alcaligenes faecalis D4 and … …Current Research in Microbiology, Vol. 8, Issue 1 · 8 Oct 2025 · 3,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Optimization to Trust Enhanced Secure Routing Optimization with IABC and CGWAA for MANETYuvaraja Panneer Selvam, Suganthi PerumalRouting in Mobile Ad Hoc Networks (MANET) presents significant challenges due to the dynamic nature of network topology. Optimal route selection and efficient route discovery are matched by effective routing in MANET. This study proposes a Hybrid Optimization to Trust-Enhanced Secure Routing Optimization (HO-TESRO) designed to address these challenges in IoT environments by integrating metrics such as link stability, bandwidth, … …Journal of Computer Science, Vol. 21, Issue 4 · 19 Mar 2025 · 4,983 accessesView PDFCite
Research ArticleOpen accessIn the abstractHigh-Dose Vitamin D3 Intake Is Associated with Decreased Symptoms of Multiple SclerosisMichelle L. Steinwart, David M. DuriancikMultiple sclerosis (MS) is one of the most widespread disabling autoimmune neurological conditions of adults between the ages of 20 and 40 globally.
