Abstract
This work addresses software quality issues introduced by Aspect-Oriented Programming (AOP). AOP aims at enhancing modularity and thus solving the problem of crosscutting concerns by capturing them into new units of modularity called aspects. With the increasing usage and acceptance of AOP, the task of assuring aspect-oriented systems' correctness has become a challenge, mainly due to its nature. Although several testing techniques have been applied and improved for object-oriented programs through the years, there is still the problem of selecting and verifying which ones can be effectively applied to AOP. This paper presents a perspective on how AOP can improve quality (when applied correctly), identifies a set of key testing issues that arise with AOP and presents weaknesses and strengths of the existing solutions to improve quality in AOP.

Abstract
This paper describes a procedural modeling methodology for urban environments, capable of reproducing real-world structures based on geographical information, operating on a spatial database engine, with applications in the field of digital gaming.

Abstract
Devices that offer positioning and route guidance depend on updated digital maps for correct functioning. Updating digital maps is a highly expensive and complex process so it became necessary to develop new ways to detect changes to the road network. Using GPS points gathered by users during their journeys, it is possible to compare the real road network with the digital map. This paper describes a methodology to detect incongruences of different road geometry, alteration of junction position, prohibited manoeuvres and traffic direction as well as a sample of the results obtained. ©2010 IEEE.

Abstract
The generation of three-dimensional models of urban environments using procedural modelling is presented as being a solution which allows financial and temporal gains, maintaining an acceptable visual fidelity level. Nevertheless, the modelling of anchor buildings (or monumental), identifying certain urban areas, needs a more careful modelling due to the high level of detail necessary, using, generally, manual modelling. We present an automation proposal of the building modelling process through the introduction of additional knowledge from textual descriptions in a procedural modelling system. The results show that the data model is flexible enough to build distinct models of churches. The data model can also provide an initial structure for high level modelling, providing the global shape for the building and the location of doors, windows or other structures. High detailed models can be built from this initial structure. The results. demonstrate also that it is possible to create a 3D model from a text and thus permitting that non-specialised users may increase effectiveness using a procedural modelling system.

Abstract
The generation of three-dimensional models of urban environments using procedural modelling is presented as being a solution that allows financial and temporal gains, maintaining an acceptable visual fidelity level. Nevertheless, the modelling of anchor buildings ( or monumental), identifying certain urban areas, needs a more careful modelling, due to the elevated level of detail necessary, using, generally, manual modelling. This paper proposes a data model to be used on an architecture for high level modelling of monumental buildings, through the introduction of additional knowledge from textual information. The firsts results shows that the data model is flexible enough to build distinct models of churches and other buildings. This data model also provides a high level three-dimensional model that can be used by other procedural modelling solutions to create detailed monumental buildings. The results also demonstrate that it is possible to use simple text to create a rudimentary 3D model, showing the way to further investigation, allowing non-specialized users to increase effectiveness using a procedural modelling system.

Abstract
The production of scientific publications is a cooperative activity that usually involves several authors. Current solutions of cooperative editors do not contemplate features such as references management and publications deposit. In this context, the authors have previously developed the PaperFlow platform that integrates the three main functionalities required to produce scientific publications: a cooperative text editor, a cooperative reference manager and a connector to scientific digital repositories. However, this approach did not included tools for a previous important stage: the conception of the scientific publications. This paper proposes an evolution of the original platform to accommodate the conception stage. For this purpose, the specification of PaperFlow/R includes new functionalities such as whiteboards, communication tools and versioning control that improve the cooperation abilities of the platform. © 2010 IEEE.
