Abstract
Forests worldwide have been devastated by fires. Forest fires cause incalculable damage to fauna and flora. In addition, a forest fire can lead to the death of people and financial damage in general, among other problems. To avoid wildfire catastrophes is fundamental to detect fire ignitions in the early stages, which can be achieved by monitoring ignitions through sensors. This work presents an integer programming approach to decide where to locate such sensors to maximize the coverage provided by them, taking into account different types of sensors, fire hazards, and technological and budget constraints. We tested the proposed approach in a real-world forest with around 7500 locations to be covered and about 1500 potential locations for sensors, showing that it allows obtaining optimal solutions in less than 20 min. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

Abstract
One important role of Enterprise Architecture aims at modeling enterprise artifacts and their relationships, ranging from the high-level concepts to physical ones such as communication networks and enterprise premises. As it is well known, these artifacts evolve over time, as well as their relationships. The dynamic nature of such artifacts has been a difficulty not only in modeling but also in keeping enterprise blueprints updated. This paper presents our approach to handle blueprints of the Enterprise Architecture, based on several years and projects in large organizations, both in the financial and telecommunication industry. We started by considering "projects" as the changing elements of Enterprise artifacts and achieve a scenario where blueprints are automatically generated and updated, and a time bar allows traveling from the past (AS-WAS), to the present (AS-IS) and to the future scenarios (TO-BE). The paper also presents an overview of the underlying model, the applied methodology and the blueprints that we found to be a valuable instrument amongst elements of different communities: Project Management, IT Governance and IT Architecture. In spite that the cases studies are targeted to the IT domain, the lessons are valid for other architectural areas. © 2009 Springer Berlin Heidelberg.

Abstract
This paper describes a joint trajectory optimized controller for a humanoid robot simulator following the real robot characteristics. As simulation is a powerful tool for speeding up the control software development, the proposed accurate simulator allows to fulfill this goal. The simulator, based on the Open Dynamics Engine and GLScene graphics library, provides instant visual feedback. The proposed simulator, with realistic dynamics, allows to design and test behaviours and control strategies without access to the real hardware in order to carry out research on robot control without damaging the real robot in the early stages of the development. The joints controller techniques, such as acceleration, speed and energy consumption minimization are discussed and experimental results are presented in order to validate the proposed simulator.
