Research ArticleOpen accessEvery word in the titleA General Strategy to Enhance Upconversion luminescence in Rare-Earth-Ion-Doped Oxide NanocrystalsGuanying Chen, Lei XuWe report a general strategy to enhance upconversion luminescence from rare-earth-doped oxide nanocrystals through tailoring the local crystal filed around rare earth ions. We show that upconversion luminescence from oxide nanocrystals of various host lattice (Y2O3, Gd2O3 and ZnO) and of diverse rare-earth-ions (such as Er3+, Yb3+/Er3+, Yb3+/Ho3+ and Yb3+/Tm3+) was enhanced by orders of magnitude through an introduction of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Feb 2016 · 7,735 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlepH Mediated Control Synthesis of Lanthanide-Doped YPO4 Upconversion Nano/MicrocrystalsMeiling Tan, Shuwei Hao, Xiangbin Meng et al.A pH-mediated rational control over the phase transformation, morphology and size of lanthanide doped YPO4 nano/microcrystals has been accomplished using a hydrothermal route. The morphology of the resulting particles evolves from the spheres, to the nanoflakes and finally to the nanorods when increasing the pH value of the reaction solution from 1 to 9, while the induction of crystal phase … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 1 Jun 2015 · 7,933 accessesView PDFCite

Review ArticleOpen accessIn the keywordsArchitecture of an Ultra-Low-Power Fully Autonomous Universal Power Conditioner of Energy Harvester for Wireless Sensor Networks: A ReviewYeo Kim Heng, Md. Shabiul Islam, Susthitha Menon et al.A fully autonomous Universal Power Conditioner (UPC) that can accept energy from any micro-energy harvester (e.g., photovoltaic, thermoelectric, electromagnetic, piezoelectric etc.) is proposed. Generally, UPC removes the need of multiple optimized source specific converters. But, the proposed UPC architecture will be Ultra-Low-Power (ULP) with maximized efficiency to support the low energy levels generated by harvesting sources. This UPC uses a … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Criterion for Determining the Ultimate Pullout Capacity of Plate Anchors in Clay by Numerical AnalysisHaixiao Liu, Fangmei Su, Zhou LiThe Ultimate Pullout Capacity (UPC) is an important index in designing and analyzing plate anchors. However, there are still uncertainties in determining the UPC through the load-displacement curves calculated from numerical analysis. The review on the existing criteria for determining the UPC also demonstrates that there has not been a generally accepted criterion and most existing criteria are not only … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 19 Jan 2015 · 8,413 accessesView PDFCite

SubhashiniPrecision agriculture utilizes cutting-edge technologies to maximize the management of crops, enhance utilization of resources, and maximize yield forecasting. This study critically analyzes 53 peer-reviewed articles to evaluate advancements in image-based stress detection and yield prediction techniques for precision agriculture. The review enumerates main issues, such as image-based analysis methods, different crop stress aspects (biotic, environmental, and abiotic), and remote … …Journal of Computer Science, Vol. 21, Issue 11 · 28 Dec 2025 · 2,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOVID-19 in the Era of Artificial Intelligence: Existing Technologies and A Strategic Model for Mitigating Future PandemicsBandar Mzel AlshammariPandemics have existed since the existence of life and will continue as life continues. Throughout many of the previous pandemics, what played a major role in decreasing their severity is how we mitigated and controlled them. The main reason for this is the time it takes for treatments and vaccinations to be developed, which usually takes a long time. Therefore, … …Journal of Computer Science, Vol. 20, Issue 5 · 20 Feb 2024 · 5,368 accessesView PDFCite
Research ArticleOpen accessIn the abstractSlime Mould Reproduction: A New Optimization Algorithm for Constrained Engineering ProblemsRajalakshmi Sakthivel, Kanmani SelvaduraiIn recent explorations of biologically inspired optimization strategies, the Slime Mould Reproduction (SMR) algorithm emerges as an innovative meta-heuristic optimization technique. This algorithm is deeply rooted in the reproductive dynamics observed in slime molds, particularly the intricate balance these organisms strike between local and global spore dispersal. By replicating this balance, the SMR algorithm deftly navigates between exploration and exploitation … …Journal of Computer Science, Vol. 20, Issue 1 · 21 Dec 2023 · 5,943 accessesView PDFCite
