To generate spatial-varying and multi-phase structures distributed in the interior of a design domain, the maximum local material volume constraints are imposed on each phase material in the neighborhood of each element in the design domain. A series of relaxations is introduced into the framework ...
This paper presented a method to simulate the spatial varying ground motion with time-frequency non-stationarity, which combined the knowledge of stochastic process and phase-difference spectrum. 本文在前人工作的基础上提出了一种直接生成具有时-频非平稳特性的空间变异地震动的方法,即随机过程理论与相位差...
Real estate policies in urban areas require the recognition of spatial heterogeneity in housing prices to account for local settings. In response to the growing number of spatially varying coefficient models in,housing applications, this study evaluated four models in terms of their spatial pa...
According to these analyses, this paper presents a set of integrated methods for nonstationary seismic ground motion simulation with greater capacity of processing multiple spatial points. In additional, Parallel Seismic Ground Motion Simulator, the parallel program for artificial generation of seismic ...

This study applied the geographically weighted poisson regression (GWPR) model to study the spatial variations in the effects of socioeconomic factors on COVID-19 Mortality in the African subregion. The performance of the GWPR model was compared to the conventional Poisson regression model. The ...
According to the working condition of high speed railway, a spatial time varying model of subgrade/track/vehicle coupling system is established for dynamic analysis of subgrade. In the spatial model, the railway structure and vehicle are dispersed into different elements, the dynamic equation of the...
We discuss how to include wind directional information in the covariance function of spatial models. Our models are based on a constructive convolution approach, wherein a spatial process is described as a convolution between a spatially varying smoothing kernel and a white noise process. We ...

Spatially varying coefficients As stated before, many studies have been done with the assumption that the relationship between the explanatory variable and the response variables in a regression model are constant across the study region [8–10]. This assumption is unrealistic for spatial processes as...
