Fernández Díaz, Gabriel Alejandro (Fecha de defensa: 2018-11-15)
Artificial system interaction with the real environment is in general based on the deployment of properly coordinated sensors and actuators, establishing between them a “dynamic control-loop”. The time to close this ...
Meseguer Pallarès, Roc (Fecha de defensa: 2012-03-02)
In collaborative learning scenarios, the use of computers and communication networks to facilitate collaboration is becoming popular, the Computer-Supported Collaborative Learning (CSCL). In face-to-face CSCL scenarios, ...
Otero Calviño, Beatriz (Fecha de defensa: 2007-04-13)
En este trabajo estamos interesados en realizar simulaciones numéricas basadas en elementos finitos con integración explícita en el tiempo utilizando la tecnología Grid.<br/>Actualmente, las simulaciones explícitas de ...

It is questionable whether DRAM will continue to scale and will meet the needs of next-generation systems. Therefore, significant effort is invested in research and development of novel memory technologies. One of the ...
Chronaki, Kallia (Fecha de defensa: 2018-11-21)
Asymmetric multi-cores (AMCs) are a successful architectural solution for both mobile devices and supercomputers. These architectures combine different types of processing cores designed at different performance and power ...
Sánchez Barrera, Isaac (Fecha de defensa: 2022-04-06)
The end of Dennard scaling has caused a stagnation of the clock frequency in computers.To overcome this issue, in the last two decades vendors have been integrating larger numbers of processing elements in the systems, ...
Anglada Sánchez, Martí (Fecha de defensa: 2020-06-09)
The computation capabilities of mobile GPUs have greatly evolved in the last generations, allowing real-time rendering of realistic scenes. However, the desire for processing complex environments clashes with the ...
Sequeira, Diogo Gonçalo (Fecha de defensa: 2022-10-31)
(English) Optical communications have been extensively investigated and enhanced in the last decades. Nowadays, they are responsible to transport all the data traffic generated around the world, from access to the core ...
Jaulmes, Luc (Fecha de defensa: 2019-06-21)
Hardware errors become more common as silicon technologies shrink and become more vulnerable, especially in memory cells, which are the most exposed to errors. Permanent and intermittent faults are caused by manufacturing ...
Figueiredo Boneti, Carlos Santieri de (Fecha de defensa: 2009-09-04)
Multithreaded processors are now common in the industry as they offer high performance at a low cost. Traditionally, in such processors, the assignation of hardware resources between the multiple threads is done implicitly, ...
Capdevila Pujol, Joan (Fecha de defensa: 2019-09-26)
Recent technological advances have radically changed the way we communicate. Today’s communication has become ubiquitous and it has fostered the need for information that is easier to create, spread and consume. As a ...
Nowack, Vesna (Fecha de defensa: 2016-01-12)
With the increased number of cores on a single processor chip, an application can achieve good performance if it splits the execution into multiple threads that run on multiple cores at the same time. To synchronize threads, ...
Mutlu, Burcu O. (Fecha de defensa: 2019-11-12)
Soft errors caused by transient bit flips have the potential to significantly impactan applicalion's behavior. This has motivated the design of an array of techniques to detect, isolate, and correct soft errors using ...
Artiaga Amouroux, Ernest (Fecha de defensa: 2014-01-17)
The advance of computing systems has brought new ways to use and access the stored data that push the architecture of traditional file systems to its limits, making them inadequate to handle the new needs. Current challenges ...
Rasol, Kurdman Abdulrahman (Fecha de defensa: 2022-01-28)
Software-Defined Networking (SDN) separates the control plane from the data plane. The initial SDN approach involves a single centralized controller, which may not scale properly as a network grows in size. Distributed ...
Santamaría Barnadas, Eduard (Fecha de defensa: 2010-06-15)
Unmanned Aircraft Systems (UAS) are rapidly gaining attention due to the increasing potential of their applications in the civil domain. UAS can provide great value performing environmental applications, during emergency ...
