A categorical approach to Weyl modules [PDF]

, 2009
Global and local Weyl Modules were introduced via generators and relations in the context of affine Lie algebras in a work by the first author and Pressley and were motivated by representations of quantum affine algebras.

Aplikasi Metode Object Based Image Analysis (OBIA) Untuk Identifikasi Atap Bangunan

Buletin Poltanesa, 2021
Salah satu permasalahan dalam proses pembuatan peta skala besar adalah belum terdapat metode ekstraksi objek secara otomatis, sehingga dijitasi secara manual masih dilakukan. Metode ekstraksi objek secara otomatis diharapkan dapat mempercepat pemetaan skala besar.

Multispectral Data and LiDAR for Enhanced Georeferencing of Gdanska Glowa's 17th‐Century Fortifications

Archaeometry, Volume 68, Issue 1, Page 94-106, February 2026.
ABSTRACT This study presents a novel remote sensing method to detect 17th‐century environmental elements associated with the historical fortifications of Gdanska Glowa in Poland. By integrating 10‐band multispectral imaging, high‐resolution (1 m) digital elevation models, vegetation metrics and random forest classification within Google Earth Engine ...

Satellite Screening of Tailings Dams With Deep Learning Model

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Tailings dam management is increasingly critical as mining operations extend to greater depths and generate more complex waste streams. To support scalable monitoring, this study establishes a harmonized benchmark of YOLOv5, YOLOv6, YOLOv8, and YOLOv10 for automated detection of tailings dams using high‐resolution satellite imagery.

Pixel-based vs object-based remote sensing for linking land use change and land value zone

Results in Earth Sciences
Land Value Zone (LVZ) is essential for spatial planning, taxation, and land management in Indonesia. However, identifying these zones still faces significant challenges, especially in linking land use change with land value.

Yield and yield components responses to plant density in cowpea grown in two savannah agro‐ecologies in Nigeria

Agrosystems, Geosciences &Environment, Volume 8, Issue 4, December 2025.
Abstract Gap‐filling is used to mitigate yield losses in different legumes. There is scanty information on this mechanism of yield compensation in the cowpea [Vigna unguiculata (L.) Walp]. This study investigated responses of yield and yield components to plant density in some accessions of cowpea at Minjibir and Shika locations.
