While scalable coherence has been extensively studied in the context of general purpose
chip multiprocessors (CMPs), GPU architectures present a new set of challenges …

This paper focuses on the identification of temporal trends involving different granularities in
clinical databases, where data are temporal in nature: for example, while follow-up visit data …

Location-based services have attracted the attention of important research in the field of
mobile computing. Specifically, different mechanisms have been proposed to process …

Among different spatial data models, the topological model for spatial regions explicitly
represents common boundaries. This model pursues the efficiency of topology-related …

Location-based services have become an increasingly interesting research area in the last
two decades. However, in many scenarios, dealing with the most precise location …

The notion of granularity is used in several areas of computing. In temporal databases,
granularity relates to the fact that the time frame associated to an event of interest (eg, an …

Spatio-temporal data are collected at high levels of detail (LoDs). Both spatial and temporal
characteristics of data can be expressed at different LoDs. Depending on the phenomenon …

Spatiotemporal data are often expressed in terms of granularities to indicate the
measurement units of the data. A granularity system usually consists of a set of granularities …

Data involving spatial and/or temporal attributes are often represented at different levels of
granularity in different source schemata. In this work, a model of such multigranular data is …

Location-based services have motivated intensive research in the field of mobile computing,
and particularly on location-dependent queries. Existing approaches usually assume that …
