3 artículosThis paper introduces a new 3D optical data storage medium using transparent glass ceramic embedded with photostimulated LiGa5O8:Mn2+ nanocrystals. This material allows for bit-by-bit optical data writing and readout, enabling 3D volumetric storage with intensity/wavelength multiplexing for increased capacity and security.
The meta-analysis compared Random Forest (RF) and Support Vector Machines (SVM) for remote sensing image classification across 251 studies. While both methods are widely used and achieve high accuracies, RF showed a recent surge in popularity, possibly due to its robustness and ease of use, and often outperformed SVM in applications like land cover mapping with larger datasets and higher resolution imagery.
Engineering students and faculty at a large, diverse university faced logistical, technical, and learning/teaching challenges during the abrupt shift to online instruction due to the COVID-19 pandemic. Key challenges for students included difficulty maintaining focus, Zoom fatigue, social disconnection, and lack of clear guidance, while faculty struggled with access to technology, online assessment methods, and providing hands-on training. Practical recommendations for improvement, including better utilization of learning management systems, alternative assessment strategies, and enhanced communication, were proposed.
