Knowing of precipitation values in different regions is always of main and strategic issues of human which has important role in short- term and long-term decisions. In order to determine of precipitation model and forecasting it, there are different models, but given that the precipitation data have a spatial autocorrelation, the spatial statistic is a powerful tool to recognition of spatial b...
OBJECTIVES To identify factors associated with human papillomavirus (HPV) vaccination and to determine the geographic distribution of vaccine uptake while accounting for spatial autocorrelation. DESIGN This study is cross-sectional in design using data collected via the Internet from the Survey of Minnesotans About Screening and HPV study. SETTING AND PARTICIPANTS The sample consists of 760...
We propose that neglect includes a disorder of representational updating. Representational updating refers to our ability to build mental models and adapt those models to changing experience. This updating ability depends on the processes of priming, working memory, and statistical learning. These processes in turn interact with our capabilities for sustained attention and precise temporal proc...
This study analyzed the dengue fever epidemic in 2002 and the socio-demographic context of the State of Rio de Janeiro, Brazil, using spatial analysis and statistical modeling. The incidence rate was calculated for resident dengue cases in the State in 2002. The study analyzed associations between incidence and socio-demographic variables and spatial autocorrelation using the Moran Global Index...
In recent years a number of empirical results indicate that humans tend to use mental models during the reasoning process. This theory claims that humans represent and reason about spatial information by constructing, inspecting, and generating alternative models to check for a putative conclusion. New results about preferred models and local transformations made it necessary to refine the clas...
LISFLOOD-FP belongs to a new generation of hydrodynamic models of flood simulation, which is implemented by a digital elevation map for the river and the waterways, route information and flow rates The LISFLOOD-FP features are two-dimensional hydraulic models: 1. based on raster 2. large scale 3. ease of formulation and high computational efficiency 4. simplicity of use 5. spatial adjustmen...
Applications of machine-learning-based approaches in the geosciences have witnessed a substantial increase over past few years. Here we present an approach that accounts for spatial autocorrelation by introducing features to models. In particular, explore two types features, namely lag and eigenvector filtering (ESF). These are used within widely random forest (RF) method, their effect is illus...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Environmental factors have both direct and indirect impacts on crime behavior decision making. This study aimed to examine what degree the occurrences of violent crimes can be affected by social built environment over space. Although a few studies attempted model rate using spatial regression models, there is lack comparison models. Particularly, eigenvector filtering type models has reportedly...
درک الگوی توزیع مکانی ماکروفون خاک بدلیل اثرات آن روی فرآیندهای اکوسیستم بسیار مهم است. لیکن اطلاعات کمی در این خصوص وجود دارد. درمورد تنوع زیستی ارگانیسم ها وجانداران خاکزی که ازاجزای مهم وکلیدی درهرسیستم اکولوژیکی هستند و در بهبود حاصلخیزی خاک و تولیدات زمین وپایداری اکوسیستم ها(ازطریق فرآیندهای بیولوژیک)نقش عمده دارند تحقیقات کمی انجام شده است. این تحقیق جهت بررسی الگوی مکانی پارامترهای تنوع...
