Cardona Nadal, Jordi (Date of defense: 2023-04-03)
(English) In the last decade performance needs in Critical Real-Time Embedded Systems (CRTES) domains like automotive, avionics, railway or space have been steadily on the rise due to the unprecedented computational power ...
Vilardell Moreno, Sergi (Date of defense: 2023-03-13)
(English) Critical Real-Time Embedded Systems (CRTES) are used in domains like transportation (e.g. avionics, automotive, space, and railway), healthcare, and industrial machinery. This subset of embedded systems requires ...
Iqbal, Masab (Date of defense: 2023-03-24)
(English) Optical communication systems are widely adopted and responsible for transporting data traffic from access to metro to core networks supporting society’s information and communication functions. As the traffic ...
Badia Sala, Rosa Maria (Date of defense: 1994-07-20)
(Català) A mesura que augmenta el nombre de transistors integrables en un xip, problemes com el desfasament del senyal de rellotge esdevenen cada cop més crítics. Altres avantatges com un consum més baix, una velocitat ...
Gutiérrez Torre, Alberto (Date of defense: 2022-11-22)
(English) In recent years IoT and Smart Cities have become a popular paradigm of computing that is based on network-enabled devices connected providing different functionalities, from sensor measures to domotic actions. ...
Aguilar Mena, Jimmy (Date of defense: 2022-11-23)
(English) The dominant programming approach for scientific and industrial computing on clusters is MPI+X. While there are a variety of approaches within the node, denoted by the ``X'', Message Passing interface (MPI) is ...
Call Barreiro, Aaron (Date of defense: 2022-11-07)
(English) Traditional data centers consist of computing nodes that possess all the resources physically attached. When there was the need to deal with more significant demands, the solution has been to either add more nodes ...
Sequeira, Diogo Gonçalo (Date of defense: 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 ...
Mahdavi, Kaveh (Date of defense: 2022-07-28)
Clustering analysis is widely used to stratify data in the same cluster when they are similar according to the specific metrics. We can use the cluster analysis to group the CPU burst of a parallel application, and the ...
Calderón Torres, Alejandro Josué (Date of defense: 2022-07-21)
The real-time control systems industry is moving towards the consolidation of multiple computing systems into fewer and more powerful ones, aiming for a reduction in size, weight, and power. The increasing demand for higher ...
Keller, Kai Rasmus (Date of defense: 2022-07-01)
With the increasing power of supercomputers, ever more detailed models of physical systems can be simulated, and ever larger problem sizes can be considered for any kind of numerical system. During the last twenty years ...
Becerra Sánchez, Enriqueta Patricia (Date of defense: 2021-09-20)
Driving a vehicle is a complex activity exposed to continuous changes such as speed limits and vehicular traffic. Drivers require a high degree of concentration when performing this activity, increasing the amount of mental ...
Tabatabaeimehr, Fatemehsadat (Date of defense: 2022-06-02)
Network automation has been long time envisioned. In fact, the Telecommunications Management Network (TMN), defined by the International Telecommunication Union (ITU), is a hierarchy of management layers (network element, ...
Peredo Andrade, Oscar Francisco (Date of defense: 2022-06-09)
Classical geostatistical methods are based on the hypothesis of stationarity, which allows to apply repetitive sampling in different locations of the spatial domain, in order to obtain enough information to infer cumulative ...
Barzegar, Sima (Date of defense: 2022-06-03)
This Ph.D. thesis focuses on the reliable autonomous operation of multilayer optical networks. The first objective focuses on the reliability of the optical network and proposes methods for health analysis related to ...
Gómez Crespo, Constantino (Date of defense: 2022-05-23)
The landscape of High Performance Computing (HPC) system architectures keeps expanding with new technologies and increased complexity. To improve the efficiency of next-generation compute devices, architects are looking ...
Sánchez Barrera, Isaac (Date of defense: 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, ...
Ramírez Lazo, Cristóbal (Date of defense: 2022-04-04)
Today there are two main vector processors design trends. On the one hand, we have vector processors designed for long vectors lengths such as the SX-Aurora TSUBASA which implements vector lengths of 256 elements (16384-bits). ...
Benedicte Illescas, Pedro (Date of defense: 2022-04-07)
Future Critical Real-Time Embedded Systems (CRTES), like those is planes, cars or trains, require more and more guaranteed performance in order to satisfy the increasing performance demands of advanced complex software ...
