Abstract—Spatio-temporal interpolation to generate voxel-field data in a space-time domain from observational data is indispensable to many spatiotemporal reconstruction and visualization of dynamic spatial phenomena. However, only very primitive interpolation methods such as nearest neighbor interpolation based on a Voronoi diagram are proposed for nominal or “class variable” data such as land...

We present some techniques for planning in temporal domains specified with the recent standard languange PDDL2.1. These techniques are implemented in LPG, a fully-automated system that took part in the third International Planning Competition (Toulouse, 2002) showing excellent performance. The planner is based on a stochastic local search method and on a graph-based representation called “Tempo...

objective: soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. so, this research has been done for achieving this purpose. methods: this...

the present study was carried out in kharkeh research station, kurdestan province, western iran to investigate the effects of the change in land use on the degradation of mol-lisols, their organic carbon content, clay mineralogy and k+ status. the study area was partly under cultivation (for over 40 years) and partly preserved as rangelands. the re-sults revealed that mollisols are the dominant...

large scale land use/cover changes and habitat fragmentation is a major factor in the distribution and functioning of ecosystems. for analysis the relationship between land use changes and their impacts on biodiversity, land cover and land use information is needed at different scales. the main goal of this study was to quantify the land use/ cover changes in arasbaran biosphere reserve, northw...

land use change is driven by interaction in space and time between humans and the environment that can be captured by computer simulation models (veldkamp and verburg, 2004). in the last few decades, land use change models have played an important role in understanding the causes, mechanisms and consequences of land use dynamics. sleuth is an open source cellular automata based land use change ...

green belt is defined as a narrow green area surrounding an urban area. shiraz green belt has been developed through 9 projects with a variety of purposes since 2005. the development of green belt is being considered in a number of iranian cities, and therefore, investigation of shiraz green belt’s purposes and challenges could contribute to an appropriate planning by decision makers. the main ...
