(English) Climate change is pushing to decarbonize worldwide economies and forcing fossil fuel-based power systems to evolve into power systems based mainly on renewable energies sources (RES). Thus, increasing the energy ...
In matrix completion, the objective is to recover an unknown matrix from a small subset of observed entries. Most successful methods for recovering the unknown entries are based on the assumption that the unknown full ...
The main objects of study in this thesis are matroids. In particular we are interested in three particular classes matroids: regular matroids, arithmetic matroids, and internally perfect matroids. Of these families, regular ...
Construction industry is known to cause major social, economic and environmental impacts on the society so that promoting sustainable construction practice affects positively and allows generating a balance among these ...
The main aim of this thesis is investigating energy sustainability in developing countries using useful indicators. As it is known, serious issues such as global warming and inefficient consumption of energy will lead to ...
The aim of this work is the study of laboratory effects on the measurement of wave impact induced loads on rigid maritime structures. A high number of experiments (more then 4000 using regular wave attacks) have been carried ...
Editorial peer review is the gateway to scientific publication. It was established to ensure that research papers were vetted by independent experts before they are published. Despite the importance of this process, its ...
La rodopsina (Rho) és el receptor visual responsable de la visió a baixa intensitat lumínica. Aquest receptor, que es troba en les cèl·lules bastó de la retina, està constituït per 7 hèlices transmembrana i és el prototip ...
This thesis presents the dynamic study of conjugate cam mechanisms with rollers follower and translational movement, to design them with the aim of retard the surface fatigue failure in the rollers. The premature failure ...
Hard coating 's thermal stability is essential due to the high temperature environment of high-speed cutting applications, while the induced phase and microstructure evolution affects the mechanical properties. In this ...
On account of environmental and safety related requirements, the majority of the most popular automotive manufacturers convey to introduce Ultra High Strength Steels (UHSS) and Press Hardened Steels (PHS) in the vehicle ...
(English) Masonry structures are among the most abundant construction typologies in the world, having been commonly built until the second half of the 20th century. The determination of the mechanical properties of these ...
Soil reinforced retaining wall structures are materiallymore efficientthan competing construction solutions such as gravity and cantilever walls. Nevertheless, the behaviour and interactions between the com ponent materials ...
Tetragonal polycrystalline zirconia, commonly stabilised with 3 mol% yttria (3Y-TZP), became one of the most interesting ceramics for biomedical applications due to its biocompatibility and high mechanical properties. Among ...
(English) Epithelial sheets form specialized 3D structures suited to their physiological roles, such as branched alveoli in the lungs, tubes in the kidney, and villi in the intestine. To generate and maintain these structures, ...
Solute transport in heterogeneous porous media in general exhibits anomalous behaviors, in the sense that it is characterized by features that cannot be explained in terms of traditional models based on the advection-dispersion ...
Living tissues are crowded and dynamic environments, in which signalling molecules and physical forces constantly act on single cells. To ensure correct tissue development and homeostasis, cells function like small processors: ...
Albeit several IoT applications have been recently deployed in several fields, including environment and industry monitoring, Smart Home, Smart Hospital and Smart Agriculture, current deployments are mostly host-oriented, ...
Les xarxes IP tradicionals utilitzen el model de transmissió "best-effort" per transportar tràfic entre clients de la xarxa. Aquest model de transmissió de tràfic no és el més adequat per les aplicacions en temps real com ...
(English) Metal clusters and single atoms have been considered as effective cocatalysts for the enhancement of photocatalytic hydrogen production dueto their singular geometric structures, electronic properties and unique ...
