Artiaga Amouroux, Ernest (Date of defense: 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 (Date of defense: 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 (Date of defense: 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 ...
López Berga, Ester (Date of defense: 2017-07-10)
Wireless community networks (WCN) are specially vulnerable to routing forwarding failures because of their intrinsic characteristics: use of inexpensive hardware that can be easily accessed; managed in a decentralized way, ...
Cugnasco, Cesare (Date of defense: 2019-03-22)
Spatial Big Data is considered an essential trend in future scientific and business applications. Indeed, research instruments, medical devices, and social networks generate hundreds of peta bytes of spatial data per year. ...
Mendoça Pedroso, Pedro Miguel (Date of defense: 2011-12-16)
The popularization of Internet has turned the telecom world upside down over the last two decades. Network operators, vendors and service providers are being challenged to adapt themselves to Internet requirements in a way ...
Sirvent Pardell, Raül (Date of defense: 2009-02-03)
Durant els darrers anys el Grid ha sorgit com una nova plataforma per la computació distribuïda. La tecnologia Gris permet unir diferents recursos de diferents dominis administratius i formar un superordinador virtual amb ...
Yazdanpanah, Fahimeh (Date of defense: 2014-06-26)
Exploiting concurrency to achieve greater performance is a difficult and important challenge for current high performance systems. Although the theory is plain, the complexity of traditional parallel programming models in ...
Tan, Xubin (Date of defense: 2018-11-26)
Task-based programming models allow programmers to express applications as a collection of tasks with dependences. They are simple to use and greatly improve programmability by using software runtimes to exploit task ...
Markovic, Nikola (Date of defense: 2015-12-22)
Through the past several decades, based on the Moore's law, the semiconductor industry was doubling the number of transistors on the single chip roughly every eighteen months. For a long time this continuous increase in ...
Cadenelli, Luca (Date of defense: 2019-12-19)
Since the last decade, the main components of computer systems have been evolving, diversifying, to overcome their physical limits and to minimize their energy footprint. Hardware specialization and heterogeneity have ...
Alcaide Portet, Sergi (Date of defense: 2023-07-19)
(English) Future Safety-Critical Systems require a boost in guaranteed performance in order to satisfy the increasing performance demands of the state-of-the-art complex software features. Ar1 approach to achieve these ...
Eguzkitza Bazar, Ane Beatriz (Date of defense: 2014-06-17)
With this thesis we present the HERMESH method which has been classified by us as a a composition domain method. This term comes from the idea that HERMESH obtains a global solution of the problem from two independent ...
Acosta Ojeda, Carmelo Alexis (Date of defense: 2009-07-07)
During the last decades, Computer Architecture has experienced a great series of revolutionary changes. The increasing transistor count on a single chip has led to some of the main milestones in the field, from the release ...
