Peer-to-peer applications enable a group of users to create a communications framework from scratch without the need of a central service provider. This is achievable via the aggregation of resources each one of them ...
Nowadays, by increasing the number of connected devices to Internet rapidly, cloud computing cannot handle the real-time processing. Therefore, fog computing was emerged for providing data processing, filtering, aggregating, ...
P2PSIP (Peer-to-Peer Session Initiation Protocol) is a protocol developed by the IETF (Internet Engineering Task Force) for the establishment, completion and modi¿cation of communication sessions that emerges as a complement ...
Nowadays, the great diffusion of advanced devices, such as smart-phones, has shown that there is a growing trend to rely on new technologies to generate and/or support progress; the society is clearly ready to trust on ...
There are new mechanisms to sequence and process the genomic code, discovering thus diagnostic tools and treatments. The file for a sequenced genome can reach hundreds of gigabytes. Thus, for further studies, we need new ...
Wave storms and river inputs have been found to be the dominant forcing mechanism of sediment transport in continental shelves dominated by medium to large rivers around the world (e.g. Drake and Cacchione, 1985; Sherwood ...
The discharge of acid mine drainage into a water reservoir may seriously affect the water quality. In this setting, sediment is commonly thought to act as a sink for pollutants. However, redox oscillations in the bottom ...
(English) Turbidity currents in reservoirs are of strong scientific interest because they can be responsible for the contribution of large amounts of fine sediments that can cause early sediment filling. The case study ...
The main objective of this thesis is to contribute to the prevention and control of the cardiovascular risk, hydration state and nutritional state in dialysis patients using non-invasive electrical impedance measurements. ...
En los últimos años se han estado utilizando medios electrónicos para automatizar y hacer más eficientes los diferentes procesos de una elección. Aún cuando esta automatización se ha presentado de manera gradual, el propósito ...
El estudio de arquitecturas de seguridad para redes de transmisión de datos adquiere cada día mayor importancia.<br/><br/>Por otra parte, es un hecho constatado que el mundo de las telecomunicaciones camina decididamente ...
Technology progress in both user devices and networks allows communications anytime and anywhere. New communication environments offer a wide range of possibilities to users, but also generate new threats. For this reason, ...
La presente tesis de enmarca dentro del área de la Seguridad de Comunicaciones. Concretamente, se estudian aquí mecanismos de seguridad adecuados a los entornos de Red de Área Local, proponiéndose y evaluándose un conjunto ...
The design rules on Reduced Beam Sections (RBS) are covered in the Eurocodes in EN1998-3 as a possible solution to improve rotation capacity of beams for the retrofit of existing structures. The design rules are very similar ...
(English) Recent decades have witnessed varying degrees of damage in underground structures, including instances of structural collapse, reported during post-earthquake hazard investigations. Therefore, the research on ...
As one of the main historical construction materials, masonry is abundant among the architectural heritage of earthquake-prone areas of the Mediterranean countries. Earthquake mitigation approaches are now focusing on ...
Este trabajo presenta un estudio de riesgo sísmico para los edificios de Mérida, Venezuela. Consiste en una evaluación de la amenaza y de la vulnerabilidad sísmicas para toda la ciudad y en un estudio más detallado de la ...
A number of mid-height steel buildings have been erected recently in Bogotá. Their seismic risk might be high, given the new microzonation of Bogotá and the lack of comprehensive previous studies; noticeably, the response ...
The seismic vulnerability of urban assets exposed to earthquake hazard represents a growing concern in the engineering field due to the potential risk of collapse for the buildings, and the associated devastating consequences ...
Un dels límits fonamentals que afecta l'eficiència de conversió en cèl·lules fotovoltaiques és la distribució espectral de la radiació solar. D'una banda, només els fotons amb energia superior al gap del semiconductor poden ...
