Different applications or users need different model (differ requirement on level of details; geometry and information), less focuses in topological element. Improper manage geometry, attribute and to...
GENERATION OF A SPATIAL INFORMATION SYSTEM FOR ARCHITECTURE WITH LASERSCANNING DATA
Cultural Heritage Terrestrial Laser Scanning Modelling Geo-Database
2016/2/29
In architectural and cultural heritage documentation, laser scanning technology today offers several opportunities to approach the
object to study and to extract manifold information levels from it....
ON TWO-STEP ESTIMATION OF A SPATIAL AUTOREGRESSIVE MODEL WITH AUTOREGRESSIVE DISTURBANCES AND ENDOGENOUS REGRESSORS
Cliff–Ord spatial model Generalized method of moments estimation Limited information estimation
2015/9/24
In this paper, we consider a spatial-autoregressive model with autoregressive disturbances,
where we allow for endogenous regressors in addition to a spatial lag of the dependent variable.
We sugges...
NON-SPATIAL AND GEOSPATIAL SEMANTIC QUERY OF HEALTH INFORMATION

With the growing amount of health information and frequent outbreaks of diseases, the retrieval of health information is given more concern. Machine understanding of spatial information can improve th...
A CACHE DESIGN METHOD FOR SPATIAL INFORMATION VISUALIZATION IN 3D REAL-TIME RENDERING ENGINE
Memory cache Disk cache 3D Rendering Engine Multi-thread, Replacement policy
2014/4/25
A well-designed cache system has positive impacts on the 3D real-time rendering engine. As the amount of visualization data getting larger, the effects become more obvious. They are the base of the 3D...

2012/7/9
A power constrained sensor network that consists of multiple sensor nodes and a fusion center (FC) is considered, where the goal is to estimate a random parameter of interest. In contrast to the distr...
Threshold Improvement of Low-Density Lattice Codes via Spatial Coupling
Low-Density Lattice Codes Spatial Coupling Information Theory
2011/9/20
Abstract: Spatially-coupled low-density lattice codes (LDLC) are constructed using protographs. Using Monte Carlo density evolution using single-Gaussian messages, we observe that the threshold of the...
In recent years, population growth models with spatial diffusion have been extensively studied by many authors (for example, see [1-5]). In this paper, a population growth model is considered with a d...
