Abstract Sea‐level rise (SLR) will cause coastal groundwater to in many urban environments. Inundation of contaminated soils by (GWR) alter the physical, biological, and geochemical conditions that influence fate transport existing contaminants. These transformed products can be more toxic and/or mobile under future driven SLR GWR. We reviewed vulnerability sites GWR a US national database case...
One of the methods used to estimate land prices is Geographically Weighted Regression (GWR). The GWR method built based on dependent and independent variables (land prices) (the spatial proximity between object other facilities). However, this study will develop variable by adding a planning zone provide complexity price estimation. This proposes an implementation mechanism setting each type as...
The traumatic traces of suicide in a society and the emotional devastation due to these losses make it very important determine causes suicide. In this study, number suicides data was used for Turkey’s 81 provinces 2019.The effects factors affecting spatial differences on were analyzed predicted with geographically weighted regression models (GWR). GWR applied different kernel functions, best m...
شاخص توپولوژیک عددی حقیقی است که به یک گراف نسبت داده می شود و تحت یک ریختی گراف ثابت می ماند. شاخص های توپولوژیک برای بررسی خواص فیزیکی-شیمیایی ترکیبات شیمیایی به کار می روند. شاخص pi در مقاله ای در سال 2009 در تلاش جهت یافتن رابطه ای دقیق برای محاسبه ی شاخص pi رأسی حاصل ضرب دکارتی گراف ها معرفی شد. بعدها کاربردهای فراوانی از این شاخص در علوم نانو و شیمی به دست آمد. مطالعه ی ریاضی ای...
Objectives. Despite the increasing evidence of the associations between alcohol availability and violence, there are still inconsistent findings on the effects of on- and off-sale alcohol outlets on violent crime. The aim of this study was to examine spatial associations between on-sale alcohol availability, neighborhood characteristics, and violent crime in a geographically isolated city in Te...
In order to better understand the effects of climate change on ecosystems, the relationship between Normalized Difference Vegetation Index (NDVI) and atmospheric constituents have been explored widely by scientists using the global technique of Ordinary Least Squared (OLS) regression analysis. However, recent studies exploring such relationships at different spatial scales have revealed that lo...
The epidemic of lung cancer in Xuanwei City, China, remains serious despite the reduction of the risk of indoor air pollution through citywide stove improvement. The main objective of this study was to characterize the influences of topography on the spatiotemporal variations of lung cancer mortality in Xuanwei during 1990-2013. Using the spatially empirical Bayes method, the smoothed mortality...
African Americans in the U.S. often live in poverty and segregated urban neighborhoods, many of which have dense industrial facilities resulting in high exposure to harmful air toxics. This study aims to explore the relationship between racial composition and cancer risks from air toxics exposure in Memphis/Shelby County, Tennessee, U.S.A. Air toxics data were obtained from 2005 National Air To...
