Research ArticleOpen accessIn the abstractOptimal Control of a Malaria Transmission Model with Saturated IncidencePerpetual Appiah, Henry Amankwah, Francis BenyahWe present a vector-host deterministic model for the transmission and control of malaria, using prevention and treatment as controls. A novel addition to our model is a new prevention function that highlights the role of prevention in reducing vector populations; an essential arsenal in the fight against malaria. Another innovation is the use of a novel treatment function, which reflects … …Journal of Mathematics and Statistics, Vol. 20, Issue 1 · 29 Feb 2024 · 5,894 accessesView PDFCite
Research ArticleOpen accessIn the abstractA GPU-Based Genetic Algorithm for the Multiple Allocation P-Hub Median ProblemAchraf Berrajaa, Ayyoub El Outmani, Abdelhamid BenainiAs the sizes of realistic hub location problems increase as time goes on (reaching thousands of nodes currently) this makes such problems difficult to solve in a reasonable time using conventional computers. This study aims to show that such problems may be solved in a short computing time and with high-quality solutions using the computational power of the GPU (actually … …Journal of Computer Science, Vol. 19, Issue 5 · 28 Apr 2023 · 6,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment and Implementation of Effective Schemes for the Use of Mineral Fertilizers in the Forest-Steppe Zone of the North Kazakhstan RegionZh. A. Nokusheva, E. Ye. Kantarbayeva, M. B. Ormanbetov et al.Nitrogen fertilizers in liquid form have become the most common ones in recent years. Since North Kazakhstan is located in a zone of risky farming, liquid fertilizers are a very productive solution. The purpose of the study was to develop and evaluate the implementation of effective schemes for the use of mineral fertilizers in the forest-steppe zone of the North … …OnLine Journal of Biological Sciences, Vol. 23, Issue 3 · 5 Jun 2023 · 5,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractUniversal Singular Optimal Control: Affine SystemsAndres Gabriel Garcia, Juan Andrés Roteta LannesIn this study, the problem of finding an optimal controller for nonlinear systems with one input and a reference tracking signal is approached. With the problem's formulation, any desired signal can be tracked instantly with a closed-loop controller without the need for integral terms. Presentation lies at the heart of optimal control. This study, however, does not consider the integral … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 14 Dec 2022 · 5,452 accessesView PDFCite
Research ArticleOpen accessIn the abstractIoT Intrusion Detection using Auto-Encoder and Machine Learning TechniquesAhmed Ridha Khudhu, Khairulmizam SamsudinIoTnetwork refers to the capability of connecting smart and various devices to asingle network for the sake of performing a particular task. Similar toconventional networks, IoT networks are vulnerable to several attacks.Therefore, IoT Intrusion Detection has caught much research attention. Severalstudies have examined the task of intrusion detection for IoT networks. Withinsuch studies, the focus was set to accommodate a … …Journal of Computer Science, Vol. 18, Issue 10 · 27 Sep 2022 · 6,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of the Degree of Soil Salinity and the Bio preparation on Productivity of Maize in the Shaulder Irrigated MassifMaksat Nurbaiuly Poshanov, Shakhislam Uzakbaevich Laiskhanov, Zhassulan Maratovich Smanov et al.During the study on the Shaulder irrigated massif, the soil salinity maps with different degrees of salinity were compiled at the large-scale 1:10000 in the GIS environment. It was found that the area of saline soils increases with depth. In the upper 0-20 cm layer, 29% is salted and in the 50-100 cm layer, up to 44% is salted. The … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 11 Feb 2022 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Utilization of Red Cabbage Extract (Brassica oleracea) in the Production of Avocado (Persea americana Mill) Freshness Indicator as Smart Packaging ElementAndi Dirpan, Muspirah Djalal, Riskawanti Rahman, Jalil GenisaThis research aimed to study and produce smart packaging indicator by utilizing red cabbage extract which could be applied to avocados. The research was conducted in a laboratory with the following stages; making red cabbage extract, preparing color indicator and applying it to smart packaging. The results showed that the soaking time and pH of the red cabbage extract solution … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 30 Sep 2021 · 7,341 accessesView PDFCite
Research ArticleOpen accessIn the abstractCuticular Chitin of the Wild Silkworm Saturnia Pyri: A Renewable Source for Applications Across Industrial SectorsZarintaj Shukurova, Yusif Shukurlu, Zarbali Khalilov, Madina SharifovaIn the context of a developing sustainable bioeconomy, the search for renewable sources of biopolymers as alternatives to traditional ones is of crucial importance. In this regard, insect cuticular waste represents a promising yet insufficiently explored raw material for obtaining chitin and chitosan. This study aimed to perform a comparative assessment of the extraction efficiency and quality of chitin and … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 7 Aug 2026 · 947 accessesView PDFCite
Research ArticleOpen accessIn the abstractAI-Integrated Probabilistic Optimization for Inventory Control Under Stochastic DemandJanardan BeheraThe identification and operationalization of increasingly nonstationary and volatile demand patterns challenge the conduct of inventory management in contemporary supply chains. The classical models, especially EOQ and static policies, rest on the stability of demand assumptions, either deterministically or distributionally, and are hence less apt under real-world uncertainty. In view of these limitations, the present study puts forward an integrated … …Journal of Mathematics and Statistics, Vol. 22, Issue 1 · 6 May 2026 · 2,217 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing Boar Epididymal Sperm Preservation: Comparative Analysis of Slicing Float-Up vs. Flushing and BTS vs. Andromed® Extenders on Sperm Motility and Morphometry TraitsMamonene Angelinah Thema, Ntuthuko Raphael Mkhize, Gerhard van der Horst et al.Epididymal sperm collection represents a valuable strategy for preserving genetics from deceased or castrated boars of superior breeding value. The two primary collection methods-slicing float-up (high sperm yield) and flushing (low blood contamination risk)-differ in sperm recovery efficiency, while semen extenders provide cryoprotective nutrients that protect against cold shock during preservation. This study compared the effects of slicing float-up versus … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 14 Mar 2026 · 1,794 accessesView PDFCite
