Availability analysis of GMPLS connections based on physical network topology
This paper presents a study of connection availability in GMPLS over optical transport networks (OTN) taking into account different network topologies. Two basic path protection schemes are considered and compared with the ...
Minimum interference routing with fast protection
One of the most effective techniques offering QoS routing is minimum interference routing. However, it is complex in terms of computation time and is not oriented toward improving the network protection level. In order to ...
Electrical design of a smart control and monitoring system for small horizontal-axis wind turbines
Ponència presentada al 20th International Conference on Renewable Energies and Power Quality (ICREPQ’22): Vigo (Spain), 27th to 29th July 2022
UdiGital.edu: experimenta, juga i aprèn a través de les TIC
Aquest projecte està inspirat en el construccionisme i combina temes d’innovació educativa, TIC a l’educació i TIC per al desenvolupament. Té un fort component de divulgació cientificotecnològica i de foment del talent i ...
A technological infrastructure to create, publish and recommend accessible open educational resources
Open Educational Resources (OERs) should provide equal access for all people, independent of their particular needs or preferences. If an OER that does not comply with web accessibility guidelines, it will hardly address ...
Realidad aumentada, videojuegos y cambio climático
In this paper, Augmented Reality (AR) and Videogames are presented as two technologies suitable to be applied (independently and mixed) to Climate Change issues. The article is centered on teaching-learning, sensitization ...
Hints for a fast precessing relativistic radio jet in LS I + 61° 303
Here we discuss two consecutive MERLIN observations of the X-ray binary LS I +61° 303 . The first observation shows a double-sided jet extending up to about 200 AU on both sides of a central source. The jet shows a bent ...
Underwater 3D Scanner Model Using a Biaxial MEMS Mirror
Underwater 3D laser scanners are an essential type of sensor used by unmanned underwater vehicles (UUVs) for operations such as navigation, inspection and object recognition and manipulation. These sensors need to be able ...
Active SLAM for Autonomous Underwater Exploration
Exploration of a complex underwater environment without an a priori map is beyond the state of the art for autonomous underwater vehicles (AUVs). Despite several efforts regarding simultaneous localization and mapping ...
Optimal Traffic Grooming in WDM using Lighttours
Recent developments in optical communications have allowed simpler optical devices to improve network resource utilization. As such, we propose adding a lambda-monitoring device to a wavelength-routing switch (WRS) allowing ...
Social Presence Approach Within the Question and Answering eLearning Model: An Experiment with a Multi-Agent System
The model of Questions Answering (Q&A) for eLearning is based on collaborative learning through questions that are posed by students and their answers to that questions which are given by peers, in contrast with the classical ...
Large-Area Photo-Mosaics Using Global Alignment and Navigation Data
Seafloor imagery is a rich source of data for the study of biological and geological processes. Among several applications, still images of the ocean floor can be used to build image composites referred to as photo-mosaics. ...
Testing PID and MPC Performance for Mobile Robot Local Path-Following
This paper outlines the online performance of a control law based on PID (proportional-integral-derivative) controllers and MPC (model predictive control) for mobile robot local path-following. Both techniques share the ...
Semi-online neural-Q_leaming for real-time robot learning
Reinforcement learning (RL) is a very suitable technique for robot learning, as it can learn in unknown environments and in real-time computation. The main difficulties in adapting classic RL algorithms to robotic systems ...
Evaluating the Effect of Intensity Standardisation on Longitudinal Whole Brain Atrophy Quantification in Brain Magnetic Resonance Imaging
Atrophy quantification is fundamental for understanding brain development and diagnosing and monitoring brain diseases. FSL-SIENA is a well-known fully automated method that has been widely used in brain magnetic resonance ...
Robustness Comparison of 15 Real Telecommunication Networks: Structural and Centrality Measurements
Multiple failures can have catastrophic consequences on the normal operation of telecommunication networks. In this sense, guaranteeing network robustness to avoid users and services being disconnected is essential. A wide ...
A fairness load balancing algorithm in HWN using a multihoming strategy
Due to the growth of the number of intelligent devices and the broadband requirements, between others technical requirements, of the new applications, suppose a new challenge in planning, maintenance and resource allocation ...
Automatic Visual Bag-of-Words for Online Robot Navigation and Mapping
Detecting already-visited regions based on their visual appearance helps reduce drift and position uncertainties in robot navigation and mapping. Inspired from content-based image retrieval, an efficient approach is the ...
Hybrid coordination of reinforcement learning-based behaviors for AUV control
This paper proposes a hybrid coordination method for behavior-based control architectures. The hybrid method takes advantages of the robustness and modularity in competitive approaches as well as optimized trajectories in ...
Adaptive integral assessment package for the A2UN@ project
This paper presents a first approach of Evaluation Engine Architecture (EEA) as proposal to support adaptive integral assessment, in the context of a virtual learning environment. The goal of our research is design an ...
