Epidemicity indices and reproduction numbers from infectious disease data in connected human populations

Andrea Rinaldo, Cristiano Trevisin, Lorenzo Mari, Marino Gatto

We focus on distinctive data-driven measures of the fate of ongoing epidemics. The relevance of our pursuit is suggested by recent results proving that the short-term temporal evolution of infection spread is described by an epidemicity index related to th ...

Geographic clusters of objectively measured physical activity and the characteristics of their built environment in a Swiss urban area

Stéphane Joost, Idris Guessous, Marco André Vieira Ruas, Cédric Gubelmann

Introduction Evidence suggests that the built environment can influence the intensity of physical activity. However, despite the importance of the geographic context, most of the studies do not consider the spatial framework of this association. We aimed t ...

GPU Rasterization for Real-Time Spatial Aggregation over Arbitrary Polygons

Anastasia Ailamaki, Eleni Tzirita Zacharatou

Visual exploration of spatial data relies heavily on spatial aggregation queries that slice and summarize the data over different regions. These queries comprise computationally-intensive point-in-polygon tests that associate data points to polygonal regio ...

On the predictive ability of mechanistic models for the Haitian cholera epidemic

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Flavio Finger, Marino Gatto

Predictive models of epidemic cholera need to resolve at suitable aggregation levels spatial data pertaining to local communities, epidemiological records, hydrologic drivers, waterways, patterns of human mobility and proxies of exposure rates. We address ...

Mixed Finite Elements for spatial regression with PDE penalization

Fabio Nobile

We study a class of models at the interface between statistics and numerical analysis. Specifically, we consider nonparametric regression models for the estimation of spatial fields from pointwise and noisy observations, which account for problem-specific ...

The role of GIScience in landscape and conservation genetics

Stéphane Joost

In its natural framework, genetic information is embedded within a geographic context. Plants and animals are directly influenced by the specific characteristics of their surrounding environment. Therefore, spatial information is a potentially important el ...

Vers une nouvelle socio-géographie de la mobilité quotidienne. Etude des mobilités quotidiennes des habitants de la région urbaine de Grenoble

A link to a wide range of spatio-temporal practices, mobility is nowadays an important factor of social relations. If the spatio-temporal practices and mobility forms are not homogenous, how can we, however, describe them, qualify and make them more compre ...

Towards Design Strategies to Deal with Spatial Uncertainty in Location-Aware Systems

Nicolas Nova

Building ubiquitous applications that exploit location requires both low-level underlying infrastructure for linking sensors and managing spatial information and also high-level representation of the measured space to produce a pleasant user experience. Ho ...

Amphibian conservation in human shaped environments

Flavio Zanini

Global biodiversity is experiencing a worrying decline. Habitats destruction, associated to their degradation and fragmentation are among the greatest causes. Amphibians are particularly interesting because they are more threatened and decline more rapidly ...
