Hostelry establishments face the challenge of devising a table and chair allocation for accommodating their customers on a daily basis. This problem scales significantly with the introduction of constraints, such as scenario obstacles or the requirement of a minimum distance separation. The TLP (Table Location Problem) and the CLP (Chair Location P...
Article
Localization Wireless Sensor Networks (WSN) represent a research topic with increasing interest due to their numerous applications. However, the viability of these systems is compromised by the attained localization uncertainties once implemented, since the network performance is highly dependent on the sensors location. The Node Location Problem (...

La educación superior necesita adaptarse constantemente a un entorno cambiante y dinámico que demanda una constante evolución en la forma de entender el proceso de enseñanza-aprendizaje, y es en este contexto que surge la innovación docente como un elemento clave para asegurar la calidad y el progreso de la educación superior y, por lo tanto, el éx...
Article
The advent of smart manufacturing (SM) has led to the creation of collaborative environments with cyber-physical systems (CPS) that generate added value. However, the performance of combined industrial operations between mobile CPS such as autonomous mobile robots (AMRs) and collaborative robots (cobots) is hampered by the high uncertainty between...
Conference Paper
The digitization of processes in the context of Smart Manufacturing enables the control and monitoring of production processes. Visual inspection of parts is a process where the surface finish of machined parts is evaluated. For this purpose, manual inspection units have been traditionally used to evaluate the validity of the parts. This manual ins...
Chapter
Autonomous Ground Vehicles (AGVs) are supposing a revolution to automate the internal transportation of modern factories following the paradigms of Industry 4.0 and Smart Manufacturing. However, the optimal integration of these mobile robots into high-precision industrial tasks requires the definition of a stable and robust localization system atta...
Chapter
Information and Communication Technologies (ICT) have great potential to transform education and university training. One of these technologies is Virtual Reality (VR), which allows students to experience and explore virtual environments that are similar to their physical world. However, the transfer of skills that students can achieve with these t...

Industrial maintenance is undergoing a process of digitalization and automation through the use of Industry 4.0 technologies. An example is the employment of digital twins which allow virtualizing assets such as a fleet of Autonomous Mobile Robots (AMR) . In this paper, we analyze two local navigation algorithms for AMRs navigation in a digitized e...
Article
Industry 4.0 technologies enable the generation of added value throughout the production process. Among them, Digital Twins (DT) allow the modelization of cyber–physical systems in the virtual world and Virtual Reality (VR) allows an immersive perspective of the behavior of industrial equipment in a digitized environment. The combination of DT and...
Article
Full-text available
Smart Manufacturing is characterized by the digitization and massive communication of Cyber-Physical Systems under the Industrial Internet of Things paradigm. However, the heterogeneity of communication protocols hinders connectivity among assets due to lack of interoperability. Moreover, the decomposition of the classical production hierarchy towa...
Chapter
The digitization of industrial assets enables automation, generating added value to manufacturing processes. Digitalization is exemplified by the use of Wireless Sensor Networks (WSN) to monitor mobile robots and personnel in the industrial plant. Based on this infrastructure, the authors propose a novel access control system without the need to in...
Chapter
Unmanned-Aerial-Vehicles (UAV) widespread use has grown significantly in recent years. Their insertion in the civil sector allows their implementation in the agricultural and industrial sectors, as well as their use for surveillance or delivery applications. However, the efficient development of these applications depends on the drone’s ability to...
Chapter
Local Positioning Systems (LPS) present higher performance and more accurate target localization than traditional GNSS systems in harsh environments. However, the Node Location Problem (NLP) stands as one of the most important problems when designing LPS since the achievement of optimized sensor distributions in space requires addressing this NP-Ha...
Chapter
The coronavirus disease (COVID-19) pandemic has challenged multiple aspects of our lives. Social distancing among other preventive measures for reducing the contagion probability have supposed a significant challenge for many establishments. Restaurants, schools, conferences are establishments founded by the congregation of participants, distribute...
Article
The efficient design of the aerodynamic surfaces in the aircraft allows the optimal performance of the vehicle and the reduction of the fuel consumption. Among these surfaces, the wing is the main contributor to the force which lifts the aircraft enabling the flight. However, the application of this force out of the center of gravity generates a mo...
Chapter
Local Positioning Systems are attracting the research interest for addressing the limitations of the Global Navigation Satellite Systems over the last few years. These ad-hoc deployments of sensors depend on the optimal disposition of the nodes for reducing the localization uncertainties. This requires the addressing of the Node Location Problem wh...
