To simulate dynamic soft geo-objects and reflect geoscientific laws, the authors discuss the characteristics, mathematical expression, parameter representation and rendering of GIS Flow Element (FE) and GIS Soft Voxel (SV). The simulation and rendering algorithms of GIS FE and GIS SV are based on particle system and metaball technology in computer graphics. The main differences are that GIS FE ...
The aim of this paper is to understand the social use and the consequences of PGIS in local communities, more specifically in Sierra Nevada, Mexico. In order to investigate the use of ICT by communities, we applied a multilevel and structurationist framework that articulates three dimensions: context, process and content. The results of our study draw attention to the implications of using PGIS...
As GIS implementations mature and GIS use expands beyond the current core GIS community the need to discover and disseminate GIS capabilities grows. The Internet and the age of distributed computing provide the technical framework on which distributed GIS is built. As key application of distributed GIS, geoportals provide a gateway to discover and access geographic Web services. Four key geopor...
Recent researches on Three-dimensional Geographic Information System (3D GIS) modeling technology were reviewed. The concept of 3D GIS modeling and its application in various fields were introduced. Essential techniques to realize 3D visualization were studied. A typical 3D GIS modeling usually contains the description and the transmission of GIS spatial data structure. GIS spatial data models ...
This paper studies the development of GIS from a new point of view, which both from the accumulation of GIS scientific articles and the evolution process of GIS using co-citation analysis. After 10 years’ slow development from 1977, the number of GIS scientific literature began to increase rapidly since the early 1990s. By using the newly developed information visualization technology, the auth...
Learning by imitation, among the most promising techniques for reinforcement learning in complex domains, critically depends on the human designer ability to provide sufficiently many demonstrations of satisfactory quality. The approach presented in this paper, referred to as DIVA (Direct Value Learning for Reinforcement Learning), aims at addressing both above limitations by exploiting simple ...
Rapid, simple, and accurate antemortem tests for tuberculosis (TB) in cattle need to be developed in order to augment the existing screening methods. In particular, as cattle vaccines are developed, such tests would allow the continuation of test-and-slaughter policies alongside vaccination. Therefore, the development of an assay that distinguishes infected from vaccinated animals (a DIVA test)...
BACKGROUND Currently, Asian lineage highly pathogenic avian influenza (HPAI) H5N1 has become widespread across continents. These viruses are persistently circulating among poultry populations in endemic regions, causing huge economic losses, and raising concerns about an H5N1 pandemic. To control HPAI H5N1, effective vaccines for poultry are urgently needed. OBJECTIVE In this study, we develo...
