Volunteer-contributed geographic data (VGI) is an important source of geospatial big that support research and applications. A major concern on VGI quality the underlying observation processes are inherently biased. Detecting hot-spots thus helps better understand bias. Enabled by parallel kernel density estimation (KDE) computational tool can run multiple GPUs (graphics processing units), this...

Kernel density estimation (KDE) is a commonly used method for spatial point pattern analysis, but it computationally demanding when analyzing large datasets. GPU-based parallel computing has been adopted to address such computational challenges. The existing GPU-parallel KDE method, however, utilizes only one GPU computing. Additionally, assumes that the input data can be held in memory all at ...

Nonparametric estimation for a probability density function that describes multivariate data has typically been addressed by kernel (KDE). A novel estimator recently developed Farmer and Jacobs offers an alternative high-throughput automated approach to univariate nonparametric based on maximum entropy order statistics, improving accuracy over KDE. This article presents extension of the single ...

The 1933 Pharmacy and Poisons Act gave the Society increased control over a wider membership; and established control by the Home Secretary of the scheduling of poisons. Holloway's coverage of the post-war period is less detailed, but, none the less, includes significant recent developments such as the Society's establishment of the College of Pharmacy Practice in 1981 and its continuing commit...
