The Levi-Civita connections of Lorentzian manifolds with prescribed optical geometries
CuboWe explicitly derive the Christoffel symbols in terms of adapted frame fields for the Levi-Civita connection of a Lorentzian \(n\)-manifold \((M, g)\), equipped with a prescribed optical geometry of Kähler-Sasaki type.

Monte Carlo-Based Spatial Optimization of Simulation Plots for Forest Growth Modeling
ISPRS International Journal of Geo-InformationAccurate placement and geometry of simulation plots are essential for spatially explicit modeling of forest ecosystems. This study introduces a Monte Carlo-based approach for optimizing the spatial alignment of simulation plots with their source polygons,

Per-Field Irrigated Crop Classification in Arid Central Asia Using SPOT and ASTER Data
Remote Sensing, 2010 The overarching goal of this research was to explore accurate methods of mapping irrigated crops, where digital cadastre information is unavailable: (a) Boundary separation by object-oriented image segmentation using very high spatial resolution (2.5–5 m)
