    Bringing social reality to multiagent and service architectures : practical reductions for monitoring of deontic-logic and constitutive norms 

    Álvarez Napagao, Sergio (Date of defense: 2016-02-08)

    As distributed systems grow in complexity, the interactions among individuals (agents, services) of such systems become increasingly more complex and therefore more difficult to constrain and monitor. We propose to view ...

    Muñoz Gama, Jorge (Date of defense: 2014-12-19)

    In the last decades, the capability of information systems to generate and record overwhelming amounts of event data has experimented an exponential growth in several domains, and in particular in industrial scenarios. ...

    Construction and technological development of immersive virtual reality for pain therapy 

    Álvarez de la Campa Crespo, Mercè (Date of defense: 2023-06-29)

    (English) Virtual reality (VR) allows not only to easily change the perceived scenario but also to control several factors associated with the sense of being in an embodied virtual avatar that would not be achievable in ...

    Contribution to geometric constraint solving in cooperative engineering 

    Vila Marta, Sebastià (Date of defense: 2003-12-01)

    DA&AI supporting tools for gas turbine’s efficiency improvement: maintenance, operation modes and performance enhancement 

    Castro Cros, Martí de (Date of defense: 2023-12-18)

    (English) Digitalization has revolutionized many industries, including the power generation sector. The availability of a vast amount of data from various systems has transformed decision-making processes in Industry. ...

    Data analysis through graph decomposition 

    Piceno, Marie Ely (Date of defense: 2020-07-27)

    This work is developed within the field of data mining and data visualization. Under the premise that many of the algorithms give as result huge amounts of data impossible to handle for the users, we work with the ...

    Deep learning architectures applied to wind time series multi-step forecasting 

    Manero Font, Jaume (Date of defense: 2020-07-14)

    Forecasting is a critical task for the integration of wind-generated energy into electricity grids. Numerical weather models applied to wind prediction, work with grid sizes too large to reproduce all the local features ...

    Definition and use of software requirement patterns in requirements engineering 

    Palomares Bonache, Cristina (Date of defense: 2016-10-04)

    The final quality of software products and services depends on the requirements stated in the Software Requirements Specifications (SRSs). However, some problems like ambiguity, incompleteness and inconsistency have been ...

    Direct tree decomposition of geometric constraint graphs 

    Tarrés Puertas, Marta Isabel (Date of defense: 2014-12-18)

    The evolution of constraint based geometric models is tightly tied to parametric and feature-based Computer-Aided Design (CAD) systems. Since the introduction of parametric design by Pro/Engineer in the 1980's, most major ...

    Document-level machine translation : ensuring translational consistency of non-local phenomena 

    Martínez Garcia, Eva (Date of defense: 2019-12-19)

    In this thesis, we study the automatic translation of documents by taking into account cross-sentence phenomena. This document-level information is typically ignored by most of the standard state-of-the-art Machine ...
