Research ArticleOpen accessIn the keywordsA Sensitivity Study of the Validation of Three Regulatory Dispersion ModelsKeith D. Harsham, Michael BennettLidar measurements were made of the dispersion of the plume from a coastal industrial plant over three weeks between September 1996 and May 1998, 67 experimental runs were obtained, mostly of 30 min duration, and these were analysed to provide plume parameters (i.e. height, vertical and lateral spreads). These measurements were supplemented by local meteorological measurements at two portable meteorological … …American Journal of Environmental Sciences, Vol. 4, Issue 1 · 29 Feb 2008 · 6,719 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Prediction Model for Predictive Maintenance Based on K-Nearest Neighbor Method for Air Navigation Equipment FacilitiesRachmat Hidayat, Ditdit Nugeraha UtamaThe aging of air navigation facilities leads to a decline in equipment performance and reliability, posing significant challenges for aviation organizations in the large-scale replacement of outdated systems, as well as in managing budgets and resources. To address these issues, a performance prediction model for equipment was developed using the K-Nearest Neighbor (KNN) method, aimed at enhancing maintenance planning and … …Journal of Computer Science, Vol. 21, Issue 4 · 4 Mar 2025 · 5,661 accessesView PDFCite
Research ArticleOpen accessIn the abstractFermentation Quality and Aerobic Stability of Silages from Forage Crops Mixed with Bamboo Silage in Southern Kyushu, JapanMitsuhiro Niimi, Mizuho Kurata, Genki Ishigaki, Yasuyuki IshiiUnderutilization of bamboo contributes to the degradation of woody environments in southern Kyushu, Japan. A novel approach to using bamboo involves processing it to finely ground silage, although this product has shown inferior digestibility and palatability compared to traditional forage crops. This study evaluated the chemical composition, fermentation quality, and aerobic stability of silages produced from Italian ryegrass, maize, and … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 22 Nov 2024 · 4,362 accessesView PDFCite
Research ArticleOpen accessIn the abstractPM2.5 Prediction Using Homogenous and Heterogenous Ensemble Learning: A Comprehensive EvaluationShrabani Medhi, Minakshi GogoiAir pollution is a global issue. PM2.5 is considered to be the most dangerous pollutant. Prediction of PM2.5 concentration is important so that effective measures can be taken beforehand. A multitude of machine learning methodologies have been employed in forecasting PM2.5 levels, utilizing diverse combinations of ensemble classifiers and regressors. However, there are three important issues that need to be … …Journal of Computer Science, Vol. 20, Issue 9 · 20 Jun 2024 · 5,186 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevention of Heat Stress in Lactating CowsVladimir Zaitsev, Vasily Korotkiy, Nadezhda Bogolyubova et al.In summer, when the air temperature rises, dairy cattle are very susceptible to heat stress, which results in a significant decline in productivity. The goal of the study is to assess how a Coniferous Energy Supplement (CES) made from raw materials derived from forestry waste affects lactating cows' ruminal digestion, milk production, and quality in extreme temperatures. Two sets of … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 19 Dec 2023 · 5,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurement of Cooling Load-Based Occupant Behavior in Under-Actuated Zones: A Time-Variance ApproachYaddarabullah, Yusuf Maulana Akbar, Aedah Binti Abd Rahman, Amna SaadThis research is dedicated to the enhancement of Heating, Ventilation, and Air-Conditioning (HVAC) systems through an innovative investigation of occupant behavior within under-actuated zones. These zones are strategically positioned to elevate indoor air quality and comfort through the intelligent utilization of HVAC systems. However, accurately measuring the cooling loads within these zones, which are inherently influenced by the presence of … …American Journal of Applied Sciences, Vol. 20, Issue 1 · 11 Dec 2023 · 6,162 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Protein Feed Additives on Skin and Fur Quality of American MinkPavel Nikolayevich Abramov, Olga Fedorovna Chernova, Nikolai Aleksandrovich Balakirev et al.The purpose of the research is to study the effect of hydrolysates on the skin and fur quality. To assess morphological parameters of skin, as well as the commercial characteristics of the raw materials obtained, we formed three groups (one control and two experimental) of 3-month-old males (25 animals in each group) and females (50 animals in each group). Control … …American Journal of Animal and Veterinary Sciences, Vol. 17, Issue 1 · 5 Feb 2022 · 6,513 accessesView PDFCite
Review ArticleOpen accessIn the abstractSurvey on Applications of Electronic NoseS. Keerthana, B. SanthiFood plays a vital role in our daily life. Providing good quality food to consumers is essential. Food quality can be accessed using the Electronic nose. Electronic nose (E-nose) is an instrument for odor analysis. E-nose mimics the human olfaction system. It is widely used in predicting the quality of foodstuffs and detecting the contamination in foods. E-nose can also … …Journal of Computer Science, Vol. 16, Issue 3 · 15 Mar 2020 · 8,179 accessesView PDFCite
