Hexagones sans centre, centres sans hexagone
Cybergeo, 2012 The triangulo-hexagonal system of Walter Christaller (Die zentralen Orte, 1933) was the subject of sharp debates among German speaking geographers from 1933 until our days.

Journal of High Energy Physics, 2022 Abstract We reduce the computation of three point function of three spinning operators with arbitrary polarizations in 𝒩 = 4 SYM to a statistical mechanics problem via the hexagon formalism. The central building block of these correlation functions is the hexagon partition function.

Superpixel Segmentation for PolSAR Images Based on Geodesic Distance
Leida xuebao, 2021 Considering the lack of similarity capabilities of the distance metric used in the traditional Polarimetric Synthetic Aperture Radar (PolSAR) image superpixel segmentation algorithm, a novel PolSAR image superpixel segmentation algorithm based on ...

Hexagonal projected symmetries [PDF]
Acta Crystallographica Section A Foundations and Advances, 2015 In the study of pattern formation in symmetric physical systems, a three-dimensional structure in thin domains is often modelled as a two-dimensional one. This paper is concerned with functions in {\bb R}^{3} that are invariant under the action of a crystallographic group and the symmetries of their projections into a function defined on a plane.

ICESat‐2/ATLAS Onboard Flight Science Receiver Algorithms: Purpose, Process, and Performance
Earth and Space Science, 2021 The Advanced Topographic Laser Altimetry System (ATLAS) is the sole instrument on the Ice, Cloud, and land Elevation Satellite 2 (ICESat‐2). Without some method of reducing the transmitted data, the volume of ATLAS telemetry would far exceed the normal X‐

Construction of rhombic triacontahedron discrete global grid systems
International Journal of Digital Earth, 2022 Discrete Global Grid System (DGGS) is a new multi-resolution geospatial data modeling and processing scheme for the digital earth. The icosahedron is commonly regarded as an ideal polyhedron for constructing DGGSs with small distortions; however, the ...

HYBRID AERIAL SENSOR DATA AS BASIS FOR A GEOSPATIAL DIGITAL TWIN [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 More and more cities declare themselves to be a smart city or plan to be the same. Smart cities require a solid data source as basis for all further actions and the urban digital twin is the basis on which all information is collected and analysed.

Tiling Generating Functions of Halved Hexagons and Quartered Hexagons [PDF]
Annals of Combinatorics, 2021 We prove exact product formulas for the tiling generating functions of various halved hexagons and quartered hexagons with defects on boundary. Our results generalize the previous work of the first author and the work of Ciucu.
