(English) This Ph.D. thesis focuses on the application of intelligent models to Discrete-Variable Quantum Key Distribution (DV-QKD) protocol. The first objective focuses on providing a method for AI-based polarization ...
With the recent switch in the design of general purpose processors from frequency scaling of a single processor core towards increasing the number of processor cores, parallel programming became important not only for ...
Over the last decade, advances in technology together with the increasing use of the Internet for everyday tasks, are causing profound changes in end-users, as well as in businesses and technology providers. The widespread ...
In the last years, hardware specialization has received renewed attention as chips approach a utilization wall. Specialized accelerators can take advantage of underutilized transistors implementing custom hardware that ...
Massively Parallel Processor systems provide the required computational power to solve most large scale High Performance Computing applications. Machines with physically distributed memory allow a cost-effective way to ...
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 ...
Dos de las limitaciones de rendimiento más importantes en los procesadores de hoy en día provienen de las operaciones de memoria y de las dependencias de control. Para resolver estos problemas, las memorias cache y los ...
Complex hardware systems become more and more ubiquitous in mission critical applications such as military, satellite, and medical to name but a few. In such applications, reliability remains a primary concern because a ...
Heterogeneous platforms had become popular to increase the computational power of the systems within a constrained power budget. They are present in several systems, from embedded platforms and mobile devices to high-end ...
Operator’s transport networks are becoming increasingly more complex due to the large number of network layers needed to support the ever increasing number of new services (e.g., video-on-demand, social media, on-line ...
Recent years have seen the emergence and ubiquitous adoption of Chip Multiprocessors (CMPs), which rely on the coordinated operation of multiple execution units or cores. Successive CMP generations integrate a larger number ...
Cloud Computing markets arise as an efficient way to allocate resources for the execution of tasks and services within a set of geographically dispersed providers from different organisations. Client applications and service ...
Increasing demand for implementing highly-miniaturized battery-powered ultra-low-cost systems (e.g., below 1 USD) in emerging applications such as body, urban life and environment monitoring, etc., has introduced many ...
The major problem in the future technology scaling is the variations in process parameters that are interpreted as imperfections in the development process. Moreover, devices are more sensitive to the environmental changes ...
Technology improvements and power constrains have taken multicore architectures to dominate microprocessor designs over uniprocessors. At the same time, accelerator based architectures have shown that heterogeneous ...
The increasing demand for large and low cost wireless coverage, ranging from campus to city wide areas, has motivated a high interest in multi-hop communications with Wireless Mesh Networks (WMN) based on IEEE 802.11s as ...
L'augment de volum de tràfic IP provocat per l'increment de serveis multimèdia com HDTV o vídeo conferència planteja nous reptes als operadors de xarxa per tal de proveir transmissió de dades eficient. Tot i que les xarxes ...
Computing technology has witnessed an inimitable progress in the last decades which is the result of CMOS technology scaling commensurate with Moore's law. Transistor feature sizes have shrunk to half at each generation, ...
Dynamically typed languages are ubiquitous in today's applications. These languages ease the task of programmers but introduce significant runtime overheads since variables are neither declared nor bound to a particular ...
This thesis takes a HW/SW collaborative approach to tackle the problem of computational inefficiency in a holistic manner. The hardware is redesigned by restraining the datapath to merely 16-bit datawidth (integer datapath ...
