Monitoring biodiversity calls for efficient monitoring techniques. Soundscape analysis is a landscape-level approach to acoustic whereby indices are calculated as proxies based on all sounds occurring in landscape, i.e. soundscape. However, it not fully understood what the influence of environmental, anthropogenic and temporal heterogeneity soundscapes mean terms species diversity. Here, we use...

In spatially distributed systems such as smart buildings and intelligent transportation systems, control of spatio-temporal patterns is an important issue. this paper, we consider a finite-horizon optimal pattern problem where the specified by signal logic formula over finite traces, which will be called SSTLf formula. We give syntax Boolean semantics SSTLf. Then, show linear encodings temporal...

In this paper, we present an extension of Oracle, named STOC (SpatioTemporal Object Cartridge), to support spatio-temporal data management in a practical way. The extension is developed as a PL/SQL package and can be integrated into Oracle to offer spatio-temporal data types as well as spatio-temporal operations for various applications. Users are allowed to use standard SQL to access spatio-te...

The spatio-temporal data is our cognition to external matter and the spatio-temporal data model is the fundamental basic to manage the spatio-temporal data. The spatio-temporal object is always changing so we need a spatio-temporal data model which can reflect the change information and change reason and roundly and exactly describe the spatio-temporal world. At the same time more and more dema...

The rapid increase in spatio-temporal applications calls for new auxiliary indexing structures. A typical spatio-temporal application is one that tracks the behavior of moving objects through location-aware devices (e.g., GPS). Through the last decade, many spatio-temporal access methods are developed. Spatio-temporal access methods focus on two orthogonal directions: (1) Indexing the past, (2)...

1) Abstract In this article we test and evaluate the implementation of a dimension of spatio-temporal topological operators within a hypercube, a multidimensional database (MDDB) structure formed by the conjunction of several dimensions. Our goal is to permit adequate Spatio-Temporal Exploration and Analysis (STEA) in the context of Automatic Position Reporting System (APRS), the amateur radio ...

In this paper I define spatio-temporal regions as pairs consisting of a spatial and a temporal component and I define topological relations between them. Using the notion of rough sets I define approximations of spatio-temporal regions and relations between those approximations. Based on relations between approximated spatio-temporal regions configurations of spatio-temporal objects can be char...
