The evolution of some epidemics, such as influenza, demonstrates common patterns both in different regions and from year to year. On the contrary, epidemics novel COVID-19 show quite heterogeneous dynamics are extremely susceptible measures taken mitigate their spread. In this paper, we propose empirical dynamic modeling predict influenza Spain’s regions. It is a non-parametric method that look...

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...

Ecological influences on health outcomes are associated with the spatial stratification of health. However, the majority of studies that seek to understand these ecological influences utilise aspatial methods. Geographically weighted regression (GWR) is a spatial statistics tool that expands standard regression by allowing for spatial variance in parameters. This study contributes to the urban ...

The development of many complex simulation applications requires collaborative effort from researchers with different domain knowledge and expertise, possibly at different locations. These simulation systems often require huge computing resources and data sets, which can be geographically distributed. In order to support collaborative model development and to cater for the increasing complexity...

Distributed Software Development (DSD) is a recent approach where the teams are geographically distributed. Some characteristics of these environments have significant impact in activities that require constant communication, shared vision and stakeholder’s cooperation, as we have in Requirements

This report experimentally assesses the effect of the underlying network in a cluster-based computing environment. The assessment is quantified by application-level benchmarking, process-level communication, and network file input/output. Two testbeds were considered-one small cluster of Sun workstations and another larger cluster composed of 32 high-end IBM RS/6000 platforms. The clusters had ...

A geographically distributed web server (GDWS) system consists of multiple server nodes interconnected by a metropolitan area network (MAN) or a wide area network (WAN). It can achieve better eÆciency in handling ever-increasing web requests than centralized web servers because its throughput will not be limited by available bandwidth connecting to a central server. The key research issue in th...

Understanding trends in ground water contaminant concentrations is complicated by the fact that ground water quality presents complex three-dimensional trends over multiple spatial scales. To address this issue we have developed a method to jointly display three-dimensional ground water quality and topographic data. This approach allows the user to: 1) identify local areas of elevated contamina...
