Geographic information systems (GISs) are one of the major applications of database systems. GISs are characterized by the huge amount of spatial data that has to be handled (in the order of thousands of terabytes, i.e. petabytes). This makes fast indexing techniques indispensable. The huge size of the databases causes indexing methods to be stored on slow secondary memory (i.e. disk), because ...
E cient allocation of communication channels is critical for the performance of wireless mobile computing systems. The centralized channel allocation algorithms proposed in literature are neither robust, nor scalable. Distributed channel allocation schemes proposed in the past are complicated and require active participation of the mobile nodes. These algorithms are unable to dynamically adjust...
the present paper aims to examine one of the technically-based approaches in the field of urban planning and urban management which started about two decades ago, and has been tested in iran over the past decade with some scientific and executive prudence. in this paper, the clue_s model, one of the models for land use changes process simulation, is used to examine its efficiency in urbanizatio...
Most estimates of the consequences of public programs rely on the cross-sectional association between region-specific programs and program outcomes. Such estimates assume that the spatial distribution of programs is random. This article reports estimates of the effects of public programs on basic human capital indicators and the biases in conventional cross-sectional estimates of program effect...
Forest fires constitute a natural disturbance factor and an agent of environmental change with local to global impacts on Earth’s processes and functions. Accurate knowledge of forest fuel extent and properties can be an effective component for assessing the impacts of possible future wildfires on ecosystem services. Our study aims to evaluate and compare the spectral and spatial information in...
The emergences of more Earth observation satellites have increased the use of satellite imagery in applications like Land cover detection, environment monitoring etc. The information is generally extracted from satellite images by classification techniques. A common Problem associated with classification process is frequent occurrence of mixed pixel. Mixed Pixels are major cause of uncertainty ...
Understanding the relationship between photosynthesis, net primary productivity and growth in forest ecosystems is key to understanding how these ecosystems will respond to global anthropogenic change, yet the linkages among these components are rarely explored in detail. We provide the first comprehensive description of the productivity, respiration and carbon allocation of contrasting lowland...
abstract disease mapping includes a set of statistical techniques that lead to provide clean maps based on estimation of the incidence, prevalence and mortality rates for the users to be able to estimate the distribution of disease reliably. the main aims of disease mapping are to: describe the spatial variation in disease incidence for the formulation of etiological hypotheses; identify area...
In this paper, we discuss two major tradeoffs, spatial and temporal tradeoffs, that appear when applying marketbased computing to multimedia network applications. The former appears between computation and communication cost, depending on how agents are distributed over network. The latter appears between reactiveness and correctness of result, depending on how the network environment dynamical...
There is mounting pressure on healthcare planners to manage and contain costs. In rural regions, there is a particular need to rationalize health service allocation to ensure the best possible coverage for a dispersed population. Rural health administrators need to be able to quantify the population affected by their allocation decisions and, therefore, need the capacity to incorporate spatial ...
