IET Collaborative Intelligent Manufacturing, Volume 6, Issue 4, December 2024.(1) An intelligent monitoring and maintenance digital twin multimodal expert reasoning system, fine‐tuned on visual language‐based large models, is proposed. (2) This system not only achieves real‐time monitoring of the transformer's operational status but also generates maintenance strategies intelligently based on operational conditions.

Orographic gravity‐wave drag over multiple bell‐shaped mountains
Quarterly Journal of the Royal Meteorological Society, Volume 150, Issue 761, Page 2397-2417, April 2024 Part B.Mountains exert a drag on the atmospheric flow through breaking gravity waves, known as orographic gravity‐wave drag (OGWD). We derive OGWD analytically for multiple three‐dimensional bell‐shaped mountains, while previous studies have derived OGWD for a single mountain. We take into account the geometric overlap between the mountains, vertical shear of

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 6, 28 March 2024.Abstract We analyze the performance of the European Centre for Medium‐Range Weather Forecasts (ECMWF) and UK Met Office (UKMO) meteorological models in predicting offshore blowing wind in coastal areas. Our attention is mainly on the Mediterranean coast, up to 200 km distance from the shore. We compare forecast neutral winds with Advanced Scatterometer

Energy Science &Engineering, Volume 12, Issue 1, Page 168-180, January 2024.Description: This work studied and proposed a mechanism for the formation of capacity and electricity prices based on the proportion of allowed income and fixed costs at different voltage levels. The genetic algorithm (GA) has been proposed to calculate the electricity capacity price and electricity quantity's electricity price at all levels of load ...
