TriangleMesh Mesh Simplification Solid Indoor Space Indoor Data IndoorGML
2018/11/8
The 3D triangle mesh is widely used to represent indoor space. One of widely used methods of generating 3D triangle mesh data of indoor space is the construction from the point cloud collected using L...
MODIFIED TRIANGLE METHOD TO ESTIMATE SOIL MOISTURE STATUS WITH MODERATE RESOLUTION IMAGING SPECTRORADIOMETER (MODIS) PRODUCTS
Remote Sensing Agriculture Soil Moisture Estimation
2015/12/28
Soil moisture condition is one of the key parameters in environmental and agricultural modeling. In this paper, a modified triangle method (Ts/VI space) is suggested. Both NDVI and EVI are used in con...
COMPARATIVE PHYLOGEOGRAPHY OF THREE CODISTRIBUTED STOMATOPODS: ORIGINS AND TIMING OF REGIONAL LINEAGE DIVERSIFICATION IN THE CORAL TRIANGLE
Allopatric speciation biodiversity center of origin
2015/12/17
The Indonesian-Australian Archipelago is the center of the world's marine biodiversity. Although many
biogeographers have suggested that this region is a "center of origin," criticism of this theory...

generalized triangle inequalities symmetric spaces and buildings applications to algebra
2015/10/14
In this paper we apply our results on the geometry of polygons in infinitesimal symmetric spaces, symmetric spaces and buildings, [KLM1, KLM2], to four problems in algebraic group theory. Two of these...
Most quasi-Monte Carlo research focuses on sampling from the unit
cube. Many problems, especially in computer graphics, are de ned via
quadrature over the unit triangle. Quasi-Monte Carlo methods fo...
Risk Assessment and Ecotoxicology:Limitations and Recommendations for Ocean Disposal of Mine Waste in the Coral Triangle
Risk Assessment Ecotoxicology:Ocean Disposal Mine Waste Coral Triangle

ANALYSIS OF TWO TRIANGLE-BASED MULTI-SURFACE REGISTRATION ALGORITHMS OF IRREGULAR POINT CLOUDS
LiDAR Surface Registration Iterative Closest Patch (ICPatch) Iterative Closest Projected Point (ICPP)
2014/6/5
The registration of multiple surface point clouds into a common reference frame is a well addressed topic, and the Iterative Closest Point (ICP) is – perhaps – the most used method when registering la...
Biped Robot with Triangle Configuration
biped robot closed chain mechanism gait analysis triangle configuration
2011/8/5
A new biped robot with the triangle configuration is presented and it is a planar closed chain mechanism. The scalability of three sides of the triangle is realized by three actuated prismatic joints.
Abstract: We show that the triangle with angles Pi/12, Pi/3 and 7*Pi/12 has the lattice property and compute this triangle's Veech group.
