El creixement experimentat tant per la web com per Internet en els últims anys ha potenciat l'introducció de servidors d'aplicacions dins de la majoria d'entorns d'execució distribuits. El servidors d'aplicacions web porten ...
Technology in the twenty-first century is rapidly developing and driving us into a new smart computing world, and emerging lots of new computing architectures. Fog-to-Cloud (F2C) is among one of them, which emerges to ...
Les últimes dècades el rendiment dels processadors i de les memòries ha millorat a diferent ritme, limitant el rendiment dels processadors i creant el conegut memory gap. Sol·lucionar aquesta diferència de rendiment és un ...
Uno de los mayores retos que debe ser afrontado por los diseñadores de micro-procesadores es el de mitigar la gran latencia de las instrucciones de carga de datos en registros. Esta tesis analiza una de las posibles ...
Network monitoring has always been a topic of foremost importance for both network operators and researchers for multiple reasons ranging from anomaly detection to tra c classi cation or capacity planning. Nowadays, as ...
Today, vast streams of structured and unstructured data have been incorporated in databases, and analytical processes are applied to discover patterns, correlations, trends and other useful relationships that help to take ...
(English) Despite groundbreaking technological innovations, the disparity between processor and memory speeds (known as Memory Wall) is still a major performance obstacle for modern systems. Hardware prefetching is a ...
Diversos motius expliquen l'estancament en el que es troba el desenvolupament del processador tradicional dissenyat per maximitzar el rendiment d'un únic fil d'execució. Per una banda, técniques agressives com la supersegmentacó ...
In this work, we evaluate aggressive undervolting, i.e., voltage underscaling below the nominal level to reduce the energy consumption of Field Programmable Gate Arrays (FPGAs). Usually, voltage guardbands are added by ...
La evolución de los procesadores siempre ha consistido en ir aumentando el rendimiento de estos, fijando como medida de este aumento de rendimiento la velocidad de proceso en la ejecución de las distintas aplicaciones. Sin ...
En esta tesis analizamos y presentamos algoritmos de ordenación secuencial y paralelo que explotan la jerarquía de memoria del computador usado y/o reducen la comunicación de los datos. Sin embargo, aunque los objetivos ...
During many years, people and governments have been warned about the increasing levels of pollution and greenhouse gases (GHG) emissions that are endangering our lives on this planet. The Information and Communication ...
It is within the capabilities of current technology to support the emerging learning paradigms. These paradigms suggest that today’s learning activities and environments are pervas ive and require a higher level of dynamism ...
The main motivation of this dissertation is the exploration of the field of online text-dependent writer recognition, in order to provide evidence of the usefulness of short sequences of text to perform identification and ...
Despite the numerous efforts of standardization, semantic issues remain in effect in many subfields of networking. The inability to exchange data unambiguously between information systems and human resources is an issue ...
The evolution of network services is closely related to the network technology trend. Originally network nodes forwarded packets from a source to a destination in the network by executing lightweight packet processing, or ...
The Internet of Things (IoT) promises a plethora of new services and applications supported by a wide range of devices that includes sensors and actuators. To reach its potential IoT must break down the silos that limit ...
