Adaptive optics and MCAO for the 4-m European Solar Telescope EST
No full textA consortium of more than 20 European solar physics institution from 15 different countries is conducting a design study for a 4 m class solar telescope which shall be situated at the Canary Islands. In this paper we introduce the AO and MCAO design concept for EST. A ground layer deformable mirror is combined with an arrangement of four deformable layer mirrors. A combination of Shack-Hartmann wave front sensors with wide and narrow fields of view is used to control the system and to achieve a corrected field of view of one arcmin.</p
La necrópolis de Los Collados de Almedinilla (Córdoba). Historiografía de un cementerio complejo
No full textAbelleira et al.[ES] Las excavaciones en la necrópolis de Los Collados realizadas por Luis Maraver y Alfaro en la segunda mitad del siglo XIX, y posteriormente las de Pierre Paris y Arthur Engels a principios del siglo XX, sirvieron para definir arqueológicamente la que sería conocida como Cultura Ibérica. Desde entonces, al margen de algunas revisiones de materiales, este yacimiento ha sido olvidado hasta el punto de que su ubicación exacta era desconocida para los investigadores. Es por ello que durante mayo y julio de 2019 se realizó una campaña de prospección y excavación que permitió localizar la necrópolis y recuperar varias tumbas y depósitos rituales. En este trabajo presentamos los resultados preliminares de ambas intervenciones.[EN] The excavations in the Necropolis of Los Collados, carried out by Luis Maraver y Alfaro in the second half of the 19th century, and afterwards, those done by Pierre Paris and Arthur Engels at the beginning of the 20th century, serve to define archeologically that which would be considered Iberian culture. Since then, apart from a few reviews of materials, this site has been forgotten to the point that its exact location was unknown to researchers. It was because of this that prospecting work and excavation were carried out in May and July 2019 that allowed archeologists to locate the necropolis and recover various tombs and ritual deposits. In this work we present the preliminary results of both interventions.Peer reviewe

Análisis constructivo y propuesta de intervención del edificio situado en la calle Barrio Nuevo, 23, El Castellar (Teruel)
No full text[ES] En este Trabajo de Fin de Grado se desarrolla el análisis constructivo y la restauración de un edificio que fue construido en 1613, se encuentra ubicado en la calle del Barrio Nuevo Nº 23, El Castellar (Teruel). Para ello se realizará el estudio del municipio al que pertenece el edificio y de su ordenación urbanística; además de estudiar el edificio constructivamente. Finalmente, se propondrá una intervención de dicho edificio para su restauración.[CA] En aquest Treball de Fi de Grau es desenvolupa l’anàlisi constructiva i la restauració d’un edifici que va ser construït l’any 1613, i que es troba ubicat al carrer del Barri Nou Nº 23, El Castellar (Teruel). Per tal d’aconseguir-ho, es realitzarà l’estudi del municipi al qual pertany l’edifici i de la seua ordenació urbanística; a més d’estudiar l’edifici constructivament. Finalment, es proposarà una intervenció d’aquest edifici per a la seua restauració.[EN] In this Final Degree Project is developed the constructional analysis and the restoration of a building that was built in 1613. It is located in the street Barrio Nuevo Nº 23, El Castellar (Teruel). This will be done by studying the municipality to which the building belongs and its urban planning. In addition to studying the building constructively. Finally, an intervention of the building for its restoration will be proposed.Guillen Collados, M. (2020).

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
A full-Stokes polarimeter for the GREGOR Fabry-Perot interferometer
No full textOne of the first post-focus instruments of the new solar telescope GREGOR will be a Fabry-Perot spectrometer, which is an upgrade of the G¨ottingen Fabry-Perot interferometer at the Vacuum Tower Telescope (VTT) on Tenerife. This spectrometer is equipped with a full-Stokes polarimeter. The modulation is performed with two ferroelectric liquid crystals, one acting nominally as quarter-wave plate, and the other as half-wave plate. A modified Savart plate serves as polarimetric beam splitter. With the present liquid crystals, the optimum wavelength range of this polarimeter is between 580 and 660 nm. The spectro-polarimeter will benefit from the capabilities of the new telescope GREGOR which will provide a spatial resolution of about 0 . 1 (75 km on the solar surface). Thus we will be able to investigate small magnetic features, and we will study their development with high cadence
