The Neo-colonial style in the Mexican architecture of the 20th century is a subject that has not been explored in depth, even though it has had a very singular development built through 3 phases: the post-revolutionary ...
This thesis analyzes the complexity of the urban system, being described with multiple variables that represent the environmental, economic, and social characters of the city. The portrayal of the urban diversity and its ...
El problema de las emisiones y su efecto directo, el cambio Climático que sufre el planeta, es de ámbito mundial, global, y en él interviene de manera directa el ser humano, como individuo y como sociedad. Esta Tesis, ...
The position analysis problem is a fundamental issue that underlies many problems in Robotics such as the inverse kinematics of serial robots, the forward kinematics of parallel robots, the coordinated manipulation of ...
(English) Lithium-Ion Batteries (LIBs) are being used in more and more areas of application. At the same time, their chemical composition and their designs are constantly evolving. Major developments are also taking place ...
In the recent years, a wide interest has been focused on research and development for the operational use of satellite remote sensing tools for Earth observation. Among different types of sensors, Synthetic Aperture Radars ...
The cosmology presented in the first half of the twentieth century by Jesuit priest and career palaeontologist, Pierre Teilhard de Chardin (Sarcenat, France, 1881 - New York; 1955), is structured around the hypothesis of ...
The human M3 muscarinic acetylcholine receptor (M3R) regulates many important physiological roles in the central and peripheral nervous systems, and it is involved in the pathophysiology of several neurodegenerative and ...
Como lo hicieron el PC e Internet en materia de información y comunicación, la Fabricación Aditiva (FA) está revolucionando los procesos de diseño y fabricación, abriendo un nuevo paradigma de producción que genera cambios ...
This study aims to analyze whether the increased use of wood for housing construction can mitigate carbon dioxide emissions and reduce embodied energy in the civil construction sector in Brazil. The emphasis is on environmental ...
Most of the algorithms that solved the resource allocation problem, used to apply greedy algorithms to select the physical nodes and shortest paths to select the physical edges, without sufficient coordination between ...
(English) In the grid-forming control of microgrids, the droop control is a widely used for the parallel operation of power inverters, but has some peculiarities as slow dynamic and inaccuracy in the power sharing. In the ...
PEMFCs are the most popular type of Fuel Cells (FCs) and traditionally use hydrogen as the fuel. One FC problem is its relative slow dynamics caused by the time constant of the hydrogen and oxygen supply systems that can ...
(English) Nowadays, the environmental concerns for conventional fossil fuel-based power generation are transforming the energy landscape into a more sustainable system. To this end, distributed generation (DG) units have ...
This thesis discusses the control of different power converters that will have a key role in future offshore wind power systems, enabling the integration of the power generated by the wind turbines into the mainland ...
L'energia eòlica ha incrementat la seva presència a molts països i s'espera que tingui encara un pes més gran en la generació elèctrica amb la implantació de la tecnologia eòlica marina. En aquest context el desenvolupament ...
The scaling of silicon technology has been ongoing for over forty years. We are on the way to commercializing devices having a minimum feature size of one-tenth of a micron. The push for miniaturization comes from the ...
As the transistor budgets outpace the power envelope (the power-wall issue), new architectural and microarchitectural techniques are needed to improve, or at least maintain, the power efficiency of next-generation processors. ...
(English) In the last decade performance needs in Critical Real-Time Embedded Systems (CRTES) domains like automotive, avionics, railway or space have been steadily on the rise due to the unprecedented computational power ...
Architecture has discussed questions about reality, honesty versus fiction and more recently about contingency, change, open project, or the participation of the inhabitants. All these concerns are collected in documentary ...
