Accurately quantifying soil organic carbon (SOC) stocks in soils is considered necessary and important for studying the soil quality and productivity, modeling the global carbon cycle, and assessing the global climate change. The objectives of this chapter are (1) to evaluate the effects of sampling density and interpolation methods on spatial distribution of SOC density (SOCD) and (2) to estim...

We present TARGIT’s Xbone memory-based analytics server and define the concept of an Inverted Data Warehouse (IDW). We demonstrate the high-performance analytics properties of this particular design, as well as its resistance to failures. Additionally, we present a large scale solution in which TARGIT Xbone and IDW are implemented incorporating Google search data. The solution is used for so-ca...

Abstract This article was conducted to perform a temporal and spatial analysis in order identify suitable climatic regions for tourism. We investigated tourism climate conditions Fars province from 2006 2016 using index (TCI). Also, modified inverse distance weighting (IDW) interpolation is applied generate the optimal pattern of TCI distribution. The relationship between accuracy critical IDW ...

This paper focuses on evaluating the impact of different data layouts on the computational efficiency of GPU-accelerated Inverse Distance Weighting (IDW) interpolation algorithm. First we redesign and improve our previous GPU implementation that was performed by exploiting the feature of CUDA dynamic parallelism (CDP). Then we implement three versions of GPU implementations, i.e., the naive ver...

The study is conducted to assess the level of noise pollution from traffic activities in urban areas (in case Thuan An city, Binh Duong province) with specific goal applying geographic information systems. (GIS) building distribution maps area. research team collected data at peak hours and normal on weekdays weekends using meters 61 survey points. Noise measurement was then interpolated IDW (I...

In this work, the inverse distance weighting (IDW) interpolation is introduced into implicit velocity correction-based immersed boundary method (IBM) for simulation of incompressible flows. original IBM, solid body must be in a uniform mesh region due to use smooth Dirac delta function, which utilized associate Lagrangian points with their surrounding Eulerian and only works meshes. The IDW has...

Precipitation is important factor affecting vegetation and controlling key ecological processes. In order to quantify spatial patterns of precipitation in Chongqing tobacco planting region, China, under ArcGIS platform, three multivariate geostatistical methods including cokriging, small grid and regression kriging, coupled with auxiliary topographic factors extracted from a 1:100000 DEM were a...

We propose to use wireless sensor networks to assess the accuracy and application of Digital Surface Models (DSM) for the study of shadowing and solar radiation over the built environment. Using the ability of sensor network data to provide information about solar radiation and predicting the exact time of the day that the Sun starts radiating a sensor, a comparative study and statistical analy...
