Research in stereoscopic 3D coding, transmission and subjective assessment methodology depends largely on the availability of source content that can be used in cross-lab evaluations. While several studies have already been presented using proprietary content, comparisons between the studies are difficult since discrepant contents are used. Therefore in this paper, a freely available dataset of high quality Full-HD stereoscopic sequences shot with a semiprofessional 3D camera is introduced in detail. The content was designed to be suited for usage in a wide variety of applications, including high quality studies. A set of depth maps was calculated from the stereoscopic pair. As an application example, a subjective assessment has been performed using coding and spatial degradations. The Absolute Category Rating with Hidden Reference method was used. The observers were instructed to vote on video quality only. Results of this experiment are also freely available and will be presented in this paper as a first step towards objective video quality measurement for 3DTV.

La Comunidad de Madrid ha tenido un pasado minero importante que ha dejado su vestigio en el territorio. Actualmente la explotación de minerales no metálicos y de rocas industriales y ornamentales continúa, pero no así la de la minería metálica que en el pasado fue abundante. Hoy en día todas estas minas están abandonadas, dando lugar a zonas degradadas con un elevado riesgo para la seguridad de las personas y de los animales terrestres que habitan por sus inmediaciones, y necesitan ser intervenidas atendiendo, además, a su integración o recuperación ecológica y paisajística en el territorio. El principal propósito de esta tesis es conocer la situación actual que presentan las minas abandonadas de metales y proponer unos modelos de actuación para la rehabilitación e integración de los espacios mineros abandonados de la Comunidad de Madrid, cuya ventaja también estriba en su posible extrapolación a otras aéreas de gestión con una problemática similar. Partiendo de una selección de cincuenta y siete minas de interior metálicas abandonadas, se ha hecho un diagnostico en función de su seguridad (riesgo), interés cultural, arqueológico e histórico y por su afección a espacios protegidos, resultando que en todas, excepto en tres de ellas, es preciso llevar a cabo medidas protectoras y de restauración e integración en el medio ambiente. El conjunto de minas catalogadas de alto riesgo para la seguridad son veintitrés, y sobre ellas se ha realizado un Análisis Clúster, en el que además de los criterios de gestión formulados: seguridad, protección del patrimonio minero-industrial e integración ecológico-paisajística, se han incorporado otros modificadores como distancia a poblaciones, caminos, pistas y vías pecuarias, y accesibilidad. Con los resultados de este análisis se obtienen una clasificación por grupos de las minas en relación con las características intrínsecas de las explotaciones preseleccionadas y la tipología de problemas que presentan, y a partir de ella se plantean soluciones viables que se concretan en la redacción de una serie de anteproyectos tipo. Una de las principales aportaciones es que se trata de un modelo de inventariocaracterización- actuación extrapolable a otros entornos similares con problemáticas parecidas. Las propuestas de actuación que figuran en los anteproyectos tipo se proponen como medidas aplicables en situaciones similares. La tesis además también incorpora una base de datos georreferenciada que permite la localización de las explotaciones mineras abandonadas, el acceso rápido a sus características y a la propuesta de restauración correspondiente. ABSTRACT The Community of Madrid had an important mining past that left its traces in the territory. Currently the explotation of non-metallic minerals and industrial and ornamental rocks continues, but not so much with the metal deposits that were abundant in the past. Today these mines are abandoned, resulting in degraded areas with a high risk to the safety of nearby people and animals that inhabit its vicinity, and they need to be intervened, by tending to their environment integration or ecological and landscape recovery. The main objective of this thesis is to know the current situation of abandoned metal mines and propose an action model for the rehabilitation and integration of abandoned mining areas of the Community of Madrid, whose advantage also is its possible extrapolation to other management areas with similar problems. From a selection of fifty-seven abandoned metal mines, a diagnosis has been made, based on safety (risk), cultural, archaeological and historical interests and how it can be related to protected areas, resulting that all but three of them need measures of protection, restoration and integration to the environment. The set of mines that are classified as a high security risk are twenty-three, and it has been made on them an Cluster Analysis, as in addition to the management formulated criteria, such as safety, protection of mining and industrial heritage and eco-landscape integration, it has been incorporated other modifying variables, such as distance to populations, roads, tracks and livestock paths, and accessibility. With the results of this analysis, a classification of similar groups of mines in relation with the intrinsic characteristics of the preselected mines and typology problems, and from it a set of viable solutions will be specified, being then drafted on a series of proposals. One of the main contributions of this research is that it consists of an inventorycharacterization- action model, which can be extrapolated to other similar environments with similar problems. The action measures that are contained in the proposals are defined as applicable to similar situations. The thesis also incorporates a geo-referenced database that allows finding the location of abandoned mines, thus giving quick access to its features and its corresponding restoration proposal.

En el presente trabajo de tesis se desarrolla, en primer lugar, un estudio de peligrosidad sísmica en Ecuador continental, siguiendo una metodología probabilista zonificada. El estudio se plantea a escala regional y presenta como principales aportaciones: 1) la elaboración de un Estado del Arte sobre Tectónica y Geología de Ecuador, concluyendo con la identificación de las principales fuentes sísmicas; 2) La confección de un Catálogo Sísmico de proyecto, recopilando información de distintas agencias, que ha sido homogeneizado a magnitud momento, Mw, depurado de réplicas y premonitores y corregido por la falta de completitud para la estimación de tasas en diferentes rangos de magnitud; 3) la propuesta de un nueva zonificación sísmica, definiendo las zonas sismogenéticas en tres regímenes tectónicos: cortical, subducción interfase y subducción in-slab; 4) la caracterización sísmica de cada zona estimando los parámetros de recurrencia y Magnitud Máxima (Mmax), considerando para este último parámetro una distribución de valores posibles en función de la sismicidad y tectónica, tras un exhaustivo análisis de los datos existentes; 5) la generación de mapas de peligrosidad sísmica de Ecuador continental en términos de aceleración pico (PGA) y espectral SA (T= 1s) , en ambos casos para periodos de retorno (PR) de 475, 975 y 2475 años; 6) La estimación de espectros de peligrosidad uniforme (UHS) y sismos de control mediante desagregación de la peligrosidad, para PR de 475 y 2475 años en 4 capitales de provincia: Quito, Esmeraldas, Guayaquil y Loja. Una segunda parte del trabajo se destina al cálculo del riesgo sísmico en el Barrio Mariscal Sucre de Quito, lo que supone incidir ya a una escala municipal. Como principales contribuciones de este trabajo se destacan: 1) definición del escenario sísmico que más contribuye a la peligrosidad en Quito, que actuará como input de cálculo del riesgo; 2) caracterización de la acción sísmica asociada a ese escenario, incluyendo resultados de microzonación y efecto local en la zona de estudio; 3) Elaboración de una Base de Datos partiendo de información catastral e identificación de las tipologías dominantes; 4) Asignación de clases de vulnerabilidad y obtención de porcentajes de daño esperado en cada clase ante la acción sísmica definida previamente, con la consiguiente representación de mapas de vulnerabilidad y daño; 5) mapas de indicadores globales del riesgo sísmico; 6) Base de datos georreferenciada con toda la información generada en el estudio. Cabe destacar que el trabajo, aunque no formula nuevos métodos, si plantea una metodología integral de cálculo del riesgo sísmico, incorporando avances en cada fase abordada, desde la estimación de la peligrosidad o la definición de escenarios sísmicos con carácter hibrido (probabilista-determinista), hasta la asignación de vulnerabilidades y estimación de escenarios de daño. Esta tesis trata de presentar contribuciones hacia el mejor conocimiento de la peligrosidad sísmica en Ecuador y el riesgo sísmico en Quito, siendo uno de los primeros estudios de tesis que se desarrolla sobre estos temas en el país. El trabajo puede servir de ejemplo y punto de partida para estudios futuros; además de ser replicable en otras ciudades y municipios de Ecuador. -------------------- ABSTRACT: ------------------ This thesis first develops a study of seismic hazard in mainland Ecuador, following a zoned, probabilistic methodology. The study considers a regional scale and presents as main contributions: 1) The development of a State of Art on the Tectonics and Geology of Ecuador, concluding with the identification of the main seismic sources; 2) The creation of a Seismic Catalog project, collecting information from different agencies, which has been homogenized to Moment magnitude, Mw, purged from aftershocks and premonitories and corrected for the lack of completeness to estimate rates in different maggnitude ranges; 3) The proposal of a new seismic zoning, defining the seismogenic zones in three tectonic regimes: cortical, subduction interface and subduction in-slab; 4) The seismic characterization of each zone, estimating the parameters of recurrence and Maximum Magnitude (Mmax), considering the latter as a distribution of possible values, depending on the seismicity and tectonics, and after a thorough analysis of the existing data; 5) Seismic hazard maps of continental Ecuador in terms of peak ground acceleration (PGA) and spectral SA(T=1), and return periods (PR) of 475, 975 and 2475 years; 6) Uniform hazard spectra (UHS) and control earthquakes obtained by hazard disaggregation, for PR 475 and 2475 years in four provincial capitals: Quito, Esmeraldas, Guayaquil and Loja. The second section focuses on the calculation of seismic risk in the Quito Mariscal Sucre parish, which is already supposed to be influencing at a municipal level. The main contributions here are the: 1) Definition of the seismic scenario that contributes most to the hazard in Quito, which acts as an input in the risk calculation; 2) Characterization of the seismic action associated with that scenario, including results of micro-zoning and local effect in the study area; 3) Development of a database, based on cadastral data and identification of key typologies; 4) Allocation of vulnerability classes and obtaining percentages of damage expected in each class faced with the seismic action previously defined, with the consequent representation of maps of vulnerability and damage; 5) Global maps of seismic risk indicators; 6) Geo-referenced database with all the information generated in the study. It should be noted that although new methods are not prescribed, this study does set a comprehensive methodology for the calculation of seismic risk, incorporating advances in each phase approached, from the hazard estimation, or definition of seismic scenarios applying a hybrid (deterministic-probabilistic) method, to the allocation of vulnerabilities and estimation of damage scenarios. This thesis aims to present contributions leading to a better understanding of seismic hazard in Ecuador and seismic risk in Quito, and is one of the first studies in the country to develop such themes. This study can serve as an example and starting point for future studies, which could replicate this methodology in other cities and municipalities.

ACTIVITY is a database on DNA/RNA site sequences with known activity magnitudes, measurement systems, sequence-activity relationships under fixed experimental conditions and procedures to adapt these relationships from one measurement system to another. This database deposits information on DNA/RNA affinities to proteins and cell nuclear extracts, cutting efficiencies, gene transcription activity, mRNA translation efficiencies, mutability and other biological activities of natural sites occurring within promoters, mRNA leaders, and other regulatory regions in pro- and eukaryotic genomes, their mutant forms and synthetic analogues. Since activity magnitudes are heavily system-dependent, the current version of ACTIVITY is supplemented by three novel sub-databases: (i) SYSTEM, measurement systems; (ii) KNOWLEDGE, sequence-activity relationships under fixed experimental conditions; and (iii) CROSS_TEST, procedures adapting a relationship from one measurement system to another. These databases are useful in molecular biology, pharmacogenetics, metabolic engineering, drug design and biotechnology. The databases can be queried using SRS and are available through the Web, http://wwwmgs.bionet.nsc.ru/systems/Activity/.

Geo-referenced catch and fishing effort data of the bigeye tuna fisheries in the Indian Ocean over 1952-2014 were analysed and standardized to facilitate population dynamics modelling studies. During this sixty-two years historical period of exploitation, many changes occurred both in the fishing techniques and the monitoring of activity. This study includes a series of processing steps used for standardization of spatial resolution, conversion and standardization of catch and effort units, raising of geo-referenced catch into nominal catch level, screening and correction of outliers, and detection of major catchability changes over long time series of fishing data, i.e., the Japanese longline fleet operating in the tropical Indian Ocean. A total of thirty fisheries were finally determined from longline, purse seine and other-gears data sets, from which 10 longline and four purse seine fisheries represented 96% of the whole historical catch. The geo-referenced records consists of catch, fishing effort and associated length frequency samples of all fisheries.

One way to do a bibliometric study is to examine each of the records that make up a database, each record and extract key areas that may disclose relevant information about the use of the database and documents in the collection . This article shows how a reference database allows to obtain important data that can reach conclusions that in some cases surprising. For this study we used the following fields of Database Control Documentary Indigenous Nationalities of Costa Rica 1979-2003: author, place of publication, publisher, year, language and support. The database analyzed has two thousand records and was developed in the Winisis. Moreover, analysis of documents was made after processing of the data, which was to export records to Excel software Winisis. After this information extracted from their chosen fields and are held by their respective separate chart or graph to present the results obtained. Furthermore, we show the application of different methods to learn more about the scientific aspects as: the Price Index, the Index of Collaboration This contribution will, first, for (as) students in the course of the race Metric Studies of Library and Information Science, National University, demonstrate and practice what you learned in this area. They may also benefit the (as) professionals from different areas, such as anthropologists (as), sociologists (as), linguists and librarians (as), among others (as).

A Amazônia vem sofrendo severas mudanças provocadas por atividades antrópicas, dentre as quais se destaca a transformação de áreas de floresta em áreas de uso agropecuário, resultando na intensificação dos processos erosivos. A erosão, com destaque ao arraste de partículas pelo escoamento superficial, causa redução da fertilidade do solo, prejudicando a produtividade agrícola, além de impactar a qualidade e quantidade dos recursos hídricos superficiais, fato agravado pelo forte regime pluviométrico e solos naturalmente pobres da região. Nesse contexto, o conhecimento dos processos erosivos, através da utilização de modelos matemáticos para predição da perda de solo, auxilia na determinação de práticas de manejo para o uso sustentável dos recursos naturais. A presente pesquisa buscou avaliar a aplicabilidade do modelo empírico RUSLE (Revised Universal Soil Loss Equation) na região, o qual considera a interação entre a energia da chuva, as características de solo e relevo, assim como os usos e manejos praticados. A pesquisa aplicou a RUSLE no trecho superior da bacia do igarapé da Prata, com uma área aproximada de 37 km², que fica localizada no município de Capitão Poço/PA, aproximadamente 160 km da capital Belém, na Meso Região Nordeste Paraense. A metodologia empregada constou da construção de uma base de dados georreferenciada, formada a partir de fontes públicas, que passaram por adequações para inserção no ambiente SIG, que quando combinados permitiram a geração de um mapa de perda de solo da área de estudo. A pequena bacia do igarapé da Prata apresentou valores da perda de solo que variaram entre 0,004 e 72,48 t/ha.ano, com uma média de 5,12 e desvio padrão de 6,97, onde aproximadamente 12% de sua área total apresentam riscos ambientais devido aos processos erosivos. E o percentual restante, para não sofrer riscos, depende de boas práticas conservacionistas.
