Abstract: The success of machine learning algorithms depends on the representation of the data used. Specific domain knowledge can be used to design good representations. However, these representations are limited to a specific problem or task, and to the amount of available labeled data. Another approach is to automatically learn generic priors that can be used in different tasks and context. In the field of natural language processing, recent work has been done in obtaining such priors by learning useful vector representation of words from unlabeled data. The representations can then be used to improve existing natural language processing systems. These word vectors are obtained using special neural network architectures trained on billions of tokens. However, most of these models are learned and evaluated on English language corpora. In this work, Word2vec, a recent neural network based toolkit for learning word representations is used on German language data. The goal is to evaluate the learned representations of words in different language processing and information retrieval tasks. In particular, a semantic-syntactic evaluation set is constructed for the German language. In addition to that, the learned word vector representations are used as features for a classifier of German language business documents. The learned features outperformed existing handcrafted features and performed similar to other state-of-the-art approaches. Resumen: El éxito de los algoritmos de aprendizaje automático depende de la representación de los datos utilizados. conocimiento de dominio específico se puede utilizar para diseñar buenas representaciones. SIN EMBARGO, representaciones de síntesis se limitan a un problema o tarea específica, y que la cantidad de datos disponibles etiquetados. Otro enfoque es aprender automáticamente priores genéricos hizo kann utilizado en diferentes tareas y el contexto. En el campo del procesamiento del lenguaje natural, los trabajos recientes se ha hecho en la obtención de distribuciones previas examinados por el aprendizaje de la representación vector útil de las palabras de datos no etiquetados. Las representaciones a continuación, se pueden utilizar para mejorar el sistema de procesamiento de lenguaje natural existente. Estos vectores de palabras se obtienen utilizando arquitecturas de redes neuronales especiales entrenados en miles de millones de fichas. Sin embargo la mayoría de los modelos de síntesis se aprenden y se evalúa el corpus idioma Inglés. En este trabajo, Word2vec, un conjunto de herramientas basadas red neuronal reciente para el aprendizaje de representación de palabra se utiliza en los datos de idioma alemán. El objetivo es evaluar las representaciones aprendido de palabras en diferentes tareas de procesamiento del lenguaje y la recuperación de información. En particular, una evaluación semántico-sintáctica conjunto se construye para el idioma alemán. Además de eso, las representaciones vectoriales de palabras aprendidas se utilizan como características para un clasificador de documentos comerciales idioma alemán. Las características aprendidas superaron características artesanales existentes y funcionando de modo similar a otros enfoques del estado de la técnica.

The excavation for the 53-story reinforced concrete One Museum Park West building (OMPW) in Chicago was constructed using combined support systems. The building was supported by caissons and a perimeter wall formed by secant piles which transitioned to tangent piles below the bottom of the cut. After installing the perimeter wall and deep foundations for the building, the excavation for the reinforced concrete central core was supported by a circular cofferdam made of sheet piles and steel ring beams. This excavation was made using conventional bottom-up excavation techniques. The excavation for the rest of the building was made using a top-down method and was laterally braced with reinforced concrete floor slabs structurally connected to the secant pile walls and the reinforced concrete core. Field performance data during construction of the OMPW basements were collected with settlement points, inclinometers and strain gages installed in the concrete basement slabs. Significant settlements were observed adjacent to the excavation during wall and deep foundation installation, central core construction and top-down excavation. The influence of concrete material time-dependence of the floor slabs on the performance during top-down excavation is evaluated and a method for the separation of temperature-related strains from the excavation-induced strains in the concrete is described. The construction of the basements is simulated with a 3D numerical structural model to study the influence of the concrete material time-dependence of the floor slabs in the excavation-induced movements resulting from top-down construction. Computed strains in the floor slabs are compared with the observed performance data collected from the strain gages. For use in numerical simulation of the entire excavation process, hypoplasticity constitutive parameters for clays (HC model) at the element test level were calibrated with tests conducted on high quality block samples obtained from the excavation of Block 37 project in Chicago. They included oedometer tests, bender element measurements, and triaxial tests following different stress probes, and were further refined with seismic cone penetration results.  The entire OMPW excavation is simulated with the calibrated parameters with a fully coupled-flow deformation, three-dimensional finite element model. Influence of the construction of secant pile walls, concrete material time-dependence, and nonlinear concrete behavior of the perimeter pile walls on the performance of the OMPW excavation is determined. Conclusions about top-down construction are drawn in light of the measured and simulated performance of the OMPW excavation.

Concessional agreements have been to many developing countries the keystone to reach development. Since the middle twentieth century up to now roads, water - wastewater systems, electricity’s generation and distribution have been operated under arrangements that foster the private sector participation. Concessional agreements seem to be an advantageous feature of project finance for a country as a whole and perhaps that is why governments have mostly opted for this option. The foregoing sum up to developing world problems, as lack of own recourses to build, operate or maintain infrastructure and inexperience of public sector in these affairs, have arisen the utilization of concessional agreements. Developing countries use to follow the models pre-established by developed countries embracing either slightly or substantial changes in the schemes. Concessions have not been the exception. The questions then, rise from two sides. From the developed countries view it is appropriate to inquire: Did concessional agreements contributed to third world countries development? Are they still been utilized? If so, what made them work? What failed? On the other hand we should ask ourselves: Have developing countries followed carefully the third world concessional schemes? Have they settled new schemes? What were developing countries’ purposes when establishing concessional agreement schemes as public policies? Have those schemes worked or not? What is the landscape in a developed country such as Germmany and in a developing country such as Colombia? A concessional agreement as a project finance´s feature depends heavily on its preparation. Structuring phase plays a major role to reach success. Project finance is a matter of risk. Implementation of concessional agreements is as well a matter of risk. Parties assume their own project responsibility and therefore they relay in the project risks allocation. Risks allocation is the first mitigation measure. A proper structuration supposes an accurate allocation of risks and a better performance of each party. This research as of an appraisal between the role of infrastructure concessions in developed and developing countries, and has as a purpose to make a comparison between both schemes regarding the management of infrastructure concessions in their structuring phase paying special attention in the risks allocation and mitigation. The foregoing study would focus in Germany and Colombia´s scenarios principally, but using as reference other cases in specific issues, if necessary.

If lncolbest deliveries the order of its clients on the same day that they requested, it would be possible to fulfill the client's requirement to receive their products in the shortest time, improving the availability of the products to clients could sale it. However, lncolbest has an order cycle time from reception of the order until! delivery takes up to 24 hours. On the other hand, this situation makes that the company will be less competitive compared with the general market of importers which have order cycles of less than 12 hours. If it will be possible to reduce the processing and dispatch time of the order through the improvement of internal processes, the time could be reduced between 12 and 18 hours, which will benefit the company since it would increase the level of customer satisfaction and It is estimated that this action would generate an increase in sales of the 2%

The focus of this study is to build, from the “bottom-up”, a market with artificially intelligent adaptative agents based on the institutional arrangement –monetary policy, regulations, trading conventions– of the Colombian Foreign Exchange Market prevailing between December 1994 and September 1999 in order to determine simple agents´ design, rules and interactions that are sufficient to create interesting behaviours at the macroscopic level – emerging patterns that replicate the properties of the time series from the case study.

Objective: Provide an instrument in Spanish for measuring and studying physicians’ career satisfaction in Andalusia, Spain. Method: It followed two general stages: An instrument adaptation and descriptive cross-sectional study. Factor analysis was performed with 16-item scale. Construct validity was verified through a correlation between the summed 16-items scale and the global item, and internal consistency reliability was estimated with a Cronbach’s alpha. Finally, physicians’ career satisfaction was measured and characteristics related to a higher level of satisfaction were explored through a multivariate logistic regression. Results: An instrument adaption into Spanish was developed. Cronbach’s alpha of the instrument was 0.92. The rate response was 40%. Mean career satisfaction was 4.36(SD=0.76) out of a possible score of 6. Multivariate logistic regression showed that physicians who reported having received non-economic incentives during last year have a level of career satisfaction 3.11(IC=1.19–8.13) times higher than those that have not received, and also that foreign physicians have a level of career satisfaction 7.81(IC=1.40–43.48) times higher than Spanish ones, controlling by personal, professional, work, and incentives factors. Conclusions: This study performed the adaptation and validation of an instrument which measures physicians’ career satisfaction in Andalusia, Spain. The methodology to translate and adapt the instrument was successful, making the method replicable in other languages and countries. The instrument demonstrated acceptable levels of internal consistency reliability and construct validity. It was found that foreign physicians have eight times higher career satisfaction, and physicians that referred having received non-economic incentives during the last year have three times higher career satisfaction.

Tale of Talesis a visual poem. The non- conventional narrative and the inherent poetry in it, reaches an emotional depth that made me wonder about the close relationship between poetry and animation - and how this union affects the reader and the audience. This dissertation is about Yuri Norstein and his point of view of poetry and animation, understanding his opinions through an interview that I did with him. During this interview I learned more about his perspective of poetry in his animation, Tale of Tales.
