High Efficiency Road Status Monitoring System

Phillip Tomé, Telmo Cunha

This paper presents an application where an integrated GPS/IMU system is used for land survey (mounted on a van), providing a significant improvement on the efficiency of the road status monitoring process. Being initially developed for aircraft navigation ...

From AOP to UML - A Bottom-Up Approach

Jörg Kienzle, Mohamed Mancona Kandé

This position paper takes a bottom-up approach that analyzes the suitability of UML for modeling aspect-oriented software, and compares it with the UML support for modeling object-oriented software. We first introduce the basic concepts of AspectJ, a state ...

A New Definition for the Concept of Role, and Why it Makes Sense

Alain Wegmann

There is widespread agreement in the object community that the concept of role is important for object modelling, but little agreement about what is to be understood by a role. In this paper, we present a new definition for the concept of role in the conte ...

Spatio-Temporal Conceptual Models: Data Structures + Space + Time

Stefano Spaccapietra, Christine Parent

Nowadays, many applications need data modeling facilities for the description of complex objects with spatial and/or temporal facilities. Responses to such requirements may be found in Geographic Information Systems (GIS), in some DBMS, or in the research ...

Modeling Spatial Data in the MADS Conceptual Model

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Pier Donini

Despite the well-established benefits of conceptual modeling for application design, current spatio-temporal conceptual models do not cope satisfactorily with designers' requirements. In this paper we first identify the goals of a spatio-temporal conceptua ...

On Spatial Database Integration

Stefano Spaccapietra, Christine Parent

This paper investigates the problems that arise when application requirements command that autonomous spatial databases be integrated into a federated one. The paper focuses on the most critical issues raised by the integration of databases of different sc ...

Evaluating the Complexity of Databases for Person Identification and Verification

For the development and evaluation of methods for person identification, verification, and other tasks, databases play an important role. Despite this fact, there exists no measure whether a given database is sufficient to train and/or to test a given algo ...

Modeling Time from a Conceptual Perspective

Stefano Spaccapietra, Christine Parent

Although many temporal models have been proposed in the literature, there is still need for a conceptual model capturing the essential semantics of time-varying information that is free of implementation concerns. This paper first discusses important crite ...

Modelling global behaviour with scenarios in object-oriented analysis

The first object-oriented analysis methods focused on the specification of the classes of a system and on the static relationships between them. Dynamic relationships between classes and the functional view of the system as a whole were neglected, and no m ...

Conceptual Modeling for Federated Geographical Information Systems over the Web

Stefano Spaccapietra, Christine Parent

A conceptual model provides the best support for federating heterogeneous datastores into a unified framework and elaborating a global consistent description of all available data. It therefore plays a central role for exchange of information within the co ...
