A Spatio-Temporal Theory of Physical Objects

We intend to introduce and characterize by means of logical axioms the basic ontological distinctions needed to reason about physical objects. The main distinction we make is between objects and their substrates matter, the regions of space they occupy and free space. Thereafter, taking space-time as a primitive, we present a spatiotemporal theory of physical objects. keywords : Spatio-Temporal...

A temporal RFID data model for querying physical objects

RFID holds the promise of real-time identifying, locating, tracking and monitoring physical objects without line of sight, and can be used for a wide range of pervasive computing applications. To achieve these goals, RFID data have to be collected, transformed and expressively modeled as their virtual counterparts in the virtual world. RFID data, however, have their own unique characteristics –...

Context-aware Modeling for Spatio-temporal Data Transmitted from a Wireless Body Sensor Network

Context-aware systems must be interoperable and work across different platforms at any time and in any place. Context data collected from wireless body area networks (WBAN) may be heterogeneous and imperfect, which makes their design and implementation difficult. In this research, we introduce a model which takes the dynamic nature of a context-aware system into consideration. This model is con...

Spatio-Temporal Queries for moving objects Data warehousing

In the last decade, Moving Object Databases (MODs) have attracted a lot of attention from researchers. Several research works were conducted to extend traditional database techniques to accommodate the new requirements imposed by the continuous change in location information of moving objects. Managing, querying, storing, and mining moving objects were the key research directions. This extensiv...

Spatio-Temporal Sensor Graphs (STSG): A data model for the discovery of spatio-temporal patterns

Developing a model that facilitates the representation and knowledge discovery on sensor data presents many challenges. With sensors reporting data at a very high frequency, resulting in large volumes of data, there is a need for a model that is memory efficient. Since sensor data is spatiotemporal in nature, the model must also support the time dependence of the data. Balancing the conflicting...
