Research ArticleOpen accessEvery word in the titleEstimation of Adaptability and Stability of Nellore Sires, based on the Productive Progeny Performance Raised in Brazilian SavannaJúlio César De Souza, Fabio Fábio Rafael Leão Fialho, Carolina Fregonesi De Souza et al.The study investigates the performance and adaptability of Nellore sires across different regions, focusing on weight traits at 205 days (W205) and 550 days (W550). Analysis reveals significant variations in progeny weight means among evaluated sires, highlighting the importance of sire selection for herd improvement. Notably, certain sires consistently exhibit superior weight traits across diverse environmental conditions, indicating their potential … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 2 Jul 2024 · 5,529 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDesign and Analysis of a Helium-Assisted Hybrid Drone for Flight Time EnhancementGeronimo Macias, Kooktae LeeIn this study, a new design of a helium-assisted hybrid drone is proposed for flight time enhancement. As is widely known, most of the drones with a Vertical Take-Off and Landing (VTOL) feature have a short operation time, limiting their capability to carry out sustainable operations for the given missions. Thus, with the clear goal of enhancing flight time, this … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 23 Dec 2022 · 6,373 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGenerator Dynamic Performance Affected by Parameter’s UncertaintyAkbar Beik Khormizi, Mohammad Reza Aghamohammadi, Mina RezaeeThis study investigates the effect of generator parameters inaccuracy on the transient stability performance of generator and power system. Normally, generator parameters are identified either by calculation based on design specification or by measurements. In both approaches the parameters are obtained with some degree of inaccuracy. Inaccuracy and uncertainty in the obtained parameters can affect the dynamic performance and transient … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,630 accessesView PDFCite
Review ArticleOpen accessIn the abstractTEC-Driven Mini Refrigerators: Recent Applications With Performance CharacteristicsTamer Guclu, Pinar Mert Cuce et al.Thermoelectric Cooling (TEC) technology has become a remarkable alternative in mini refrigerator applications in recent years, thanks to its lack of moving parts, silent operation, compact structure and environmentally friendly features. This study aims to examine the current usage areas, performance characteristics, and engineering challenges of TEC systems in mini refrigerator applications with a holistic approach. Experimental and theoretical studies … …Energy Research Journal, Vol. 14, Issue 1 · 23 Dec 2025 · 3,306 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of NaCl on the Stability of Ab3 Lipase from Sphingobacterium sp. that Co-Expressed with LEA K Using In silico ApproachIbrahim Muhammad et al.This study explores how sodium chloride (NaCl) influences the binding affinity and stability of the Ab3 lipase-LEA K complex when interacting with olive oil, using molecular docking techniques. The docking simulations, conducted with AutoDock Vina, reveal that the presence of NaCl significantly enhances the binding affinity of the enzyme-substrate complex, increasing it from-6.55 kcal/mol in the absence of salt to-7.81 … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 9 Mar 2025 · 5,599 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvanced Hierarchical Deep Learning Approach for Intrusion Detection: Hyperparameter Tuning and Performance Evaluation on the CICIDS DatasetAjeet Singh, Azath M, Shahazad Niwazi Qurashi et al.Intrusion Detection Systems (IDS) are essential in the communication security and integrity of contemporary network architectures. This study introduces a novel advanced hierarchical deep learning model for network intrusion detection using the CICIDS dataset-2019. To improve the detection accuracy, the proposed model architecture builds several deep learning layers embedded with hyperparameters' optimization. Additional preprocessing steps, including over-sampling and min-max scaling, … …Journal of Computer Science, Vol. 21, Issue 11 · 26 Dec 2025 · 2,148 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing Quality of Service of Video Streaming Applications Over Vehicular Ad-Hoc NetworksPooja Sharma, Ajay KaulVehicular ad-hoc networks play quite an important role in communication as it is challenging to have communication across VANET nodes because of high mobility. Video streaming applications over ad-hoc networks are quite difficult because of more mobility of VANET nodes. There are various existing techniques to optimize or improve the video dissemination over ad-hoc networks. Video streaming applications need a … …Journal of Computer Science, Vol. 21, Issue 7 · 30 Jun 2025 · 3,387 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Palm Kernel Cake Based Biosupplement Biscuits on Nutrient Utilization, Growth Performance, and Metabolic Responses in Male Ettawah GoatsTintin Rostini, Suharlina, Achmad Jaelani et al.Palm Kernel Cake (PKC), a major by-product of the palm oil industry, has considerable potential as an alternative feed ingredient for ruminants because of its wide availability, moderate protein content, and economic value. However, its utilization is often constrained by high fiber and lignocellulosic components that may limit nutrient digestibility. This study evaluated the effects of PKC-based biosupplement biscuits as … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 22 Oct 2026 · 312 accessesView PDFCite
