Smart grid technology enhances our comprehension and reliability of the power grid, leveraging Phasor Measurement Unit (PMU) data-time-synchronized, high-frequency measurements gathered across the US power grid. This paper employs machine learning techniques to effectively analyze the vast PMU data in Wide Area Monitoring Systems (WAMS) for power grid event detection and classification. Analyzing several months of real-world PMU data, the paper focuses on machine learning for fast, precise event detection and classification, corroborated by utility event logs. Practical challenges like feature extraction, dimensionality reduction, and model selection are addressed. A novel feature yielding improved results is discovered, and a supplementary algorithm for detecting small power grid faults is developed. The final algorithm is validated using a month-long real PMU data set, demonstrating its capability in accurately identifying power grid events in near real-time.

Indonesia is a country with a vast archipelago and rich biodiversity, particularly in the province of Aceh. However, challenges are often encountered when exploring biodiversity due to limited information access. Providing a comprehensive source of information in this context is therefore important. This study is aimed to design and develop the Aceh Biodiversity Application, which was designed for Android-based mobile devices. In our implementation, the waterfall model is used as development method to build the application which are consisted of two core elements including the back-end REST API and the front-end Android application. The application also uses three different roles to differentiate the access, those are contributors, testers, and administrators. Finally, the functionalities testing were applied using black-box testing after the development phase. In addition, the usability testing was performed using the Post Study Usability Questionnaire (PSSUQ) method. The PSSUQ results showed the efficiency of the application, with an average usability score of 5.85, signifying a high level of usability.
We introduce a data-driven approach to learn a generalized kinetic collision operator directly from molecular dynamics. Unlike the conventional (e.g., Landau) models, the present operator takes an anisotropic form tha...
