(English) The topic of this thesis is the engineering of values for autonomous agents. This is realised through the formulation, design and implementation of new functionalities for autonomous agents that enable reasoning ...
In 1925, Lilienfeld patented the basic principle of field effect transistor (FET). Thirty-four years later, Kahng and Atalla invented the MOSFET. Since that time, it has become the most widely used type of transistor in ...
Planktonic cnidarians are those species or their stages in the phylum Cnidaria that spent their life in the water column and therefore, are tightly linked to oceanographic dynamics and water mass structures, such as fronts ...
During the last decades, human beings have experienced a significant enhancement in the quality of life thanks in large part to the fast evolution of Integrated Circuits (IC). This unprecedented technological race, along ...
This research aims to enumerate, classify and validate the variables defining a roundabout in terms of geometric, dynamic, road-safety and accident prevention. In the first instance an initial list of variables has been ...
La tesis resalta los valores de El Vedado de La Habana: particular retícula del siglo XIX para una singular ciudad jardín extensa, gradualmente transformada y progresivamente central. Las variaciones que enriquecen su ...
Term unification is a basic operation in several areas of computer science, specially in those related to logic. Generally speaking, it consists on solving equations over expressions called terms. Depending on the kind of ...
This thesis explores a very well understood area of physics: computational structural dynamics. The aim is to stretch its boundaries by merging it with another very well established discipline such as structural design and ...
This thesis is about the stabilization of the numerical solution of the Euler and Navier- Stokes equations of compressible flow. When simulating numerically the flow equations, if no stabilization is added, the solution ...
In this thesis the finite and spectral element methods (FEM and SEM, respectively) applied to problems in atmospheric simulations are explored through the common thread of Variational Multiscale Stabilization (VMS). This ...
Vegetable Fiber Reinforced Cement Composite Materials (VFRCC) have emerged as a potential construction material, providing adequate load-bearing capacity and ductility for non-structural applications. VFRCC have good ...
The box-girder is currently the solution for large prestressed concrete bridges, being most used today in steel and mixed structures. Their widespread use is due to the strength characteristics and versatility, using various ...
Tunable laser sources in different spectral regions are of interest for a variety of applications including spectroscopy, trace gas sensing, medical diagnostics, LIDAR and material processing. Existing lasers have limited ...
Quantum information is a fascinating field that studies situations in which information is encoded as quantum states. This encoding is affected by quantum physical effects (such as superposition or entanglement) and its ...
This thesis presents the study and analysis of the Vessel Traffic Services (VTS), from its origins to the present, with further evaluation of future trends. Examining the current trend in terms of technologies that are ...
La dependència actual dels combustibles fòssils en la majoria de sectors industrials i domèstics no és sostenible ni a curt ni a llarg termini. Això està obligant a plantejar alternatives a la majoria de sectors industrials ...
Many historical objects have coatings or varnish layers on the surface. In order to determine their conservation and historical contextualization is necessary to know its origin, why they were applied, the application ...
(English) Light is a powerful non invasive tool for probing matter down to its fundamental molecular properties. The past three decades saw advent of metallic nanoantennas engineered to concentrate light into sub diffraction ...
This dissertation deals with four topics. The first three are in the same environment, the transmission paths. The fourth refers to the synthesis of subsystems and more specifically to two subsystems linked by any number ...
Constantinos A. Doxiadis (1913-1975) was an important figure in the realm of postwar urbanism, and yet his contribution has been largely neglected. This study reviews his trajectory and analyzes key projects related to ...
