Dynamically updated personalized recommendations for broadcast television

The large number of channels available on television can make the process of searching for the appropriate TV channel cumbersome and time consuming. This disclosure describes techniques to make real-time personalized recommendations for live TV programming, implemented with the user’s permission. The recommendations are based on the application of a trained machine learning model. Upon being turned on, the TV is automatically tuned to a channel showing the program that is identified as being most likely to be watched by the user, chosen from all programs available at that time. Further, the user is shown a dynamically updated personalized shortlist of other channels that are broadcasting programs of likely interest to the user. Further, a notification can be shown to alert the user when a channel other than the one currently being watched starts broadcasting a program the user is likely to find of greater interest that the one on the current channel

Additionally, the one or more machine-learned models can provide tailored exercises to a user based on one or more learning objectives associated with the user

Design Parameter Analysis of Point Absorber WEC via an Evolutionary-Algorithm-Based Dimensioning Tool

Wave energy conversion has an essential difference from other renewable energies since the dependence between the devices design and the energy resource is stronger. Dimensioning is therefore considered a key stage when a design project of Wave Energy Converters (WEC) is undertaken. Location, WEC concept, Power Take-Off (PTO) type, control strategy and hydrodynamic resonance considerations are some of the critical aspects to take into account to achieve a good performance. The paper proposes an automatic dimensioning methodology to be accomplished at the initial design project stages and the following elements are described to carry out the study: an optimization design algorithm, its objective functions and restrictions, a PTO model, as well as a procedure to evaluate the WEC energy production. After that, a parametric analysis is included considering different combinations of the key parameters previously introduced. A variety of study cases are analysed from the point of view of energy production for different design-parameters and all of them are compared with a reference case. Finally, a discussion is presented based on the results obtained, and some recommendations to face the WEC design stage are given

A macroscopic performance analysis of NASA’s northrop grumman RQ-4A

This work was partially funded by the Ministerio de Economia y Competitividad of Spain under Contract TRA2016-77012-R and by EUROCONTROL acting on behalf of the SESAR Joint Undertaking (the SJU) and the European Union as part of Work Package E in the SESAR ProgrammeThis paper presents the process of identification, from a macroscopic point of view, of the Northrop Grumman RQ-4A Global Hawk Remote-Piloted Aircraft System from real, but limited flight information. Performance parameters and operational schemes will be extracted by analyzing available data from two specific science flights flown by the Global Hawk back in 2010. Each phase of the flight, take-off, climb, cruise climb, descent and landing, is analyzed from various points of view: speed profile, altitude, climb/descent ratios and rate of turn. The key performance parameters derived from individual flights will be confirmed by performing a wider statistical validation with additional flight trajectories. Derived data are exploited to validate a simulated RQ-4A vehicle employed in extensive real-time air traffic management simulated integration exercises and to complement the development of a future RQ-4A trajectory predictor.Peer ReviewedPostprint (published version

Augmented graphic thinking in Geometry: developable architectural surfaces in experimental pavilions

We will analyze how the incorporation of digital manufacturing in our schools is motivating a deep reflection about the need to be familiar with both the foundations of geometry as well as with more advanced knowledge. The reinterpretation of our inherited graphic design discipline in light of current digital tools can open up new fields of study and work, such as is occurring in the field of developable surfaces, warped surfaces and many others. In addition, through non-linear graphic processes and digital tools of parametric design, we can arrive at an "expanded graphic thinking" that we can place at the service of production and morphological research. Thus, the old descriptive geometry - geometry based on graphics – comes to serve a cybernetically enlarged mind. We will present four experimental pavilions resulting from several workshops on geometry and digital manufacturing carried out in collaboration between the University of Seville and several Ibero-American Universities. Based on the deep geometric knowledge of developable helical surfaces and surfaces of equal slope, a guided exercise is proposed to approach the design, manufacturing and assembly phases of these architectural installations on a real scale

Real-time simulations to evaluate the RPAS integration in shared airspace

This paper presents the work done during the first year in the WP-E project ERAINT (Evaluation of the RPAS-ATM Interaction in Non-Segregated Airspace) that intends to evaluate by means of human-in-the-loop real-time simulations the interaction between a Remotely Piloted Aircraft System (RPAS) and the Air Traffic Management (ATM) when a Remotely Piloted Aircraft (RPA) is being operated in shared airspace. This interaction will be evaluated from three different perspectives. First, the separation management, its results are presented in this paper. Secondly, during the next year, the contingency management, also including loss of link situations and, lastly, the capacity impact of such operations in the overall ATM system. The used simulation infrastructure allows to simulate realistic exercises from both the RPAS Pilot-in-Command (PiC) and the Air Traffic Controller (ATCo) perspectives. Moreover, it permits to analyze the actual workload of the ATC and to evaluate several support tools and different RPAS levels of automation from the PiC and ATC sides. The simulation results and the usefulness of the support tools are presented for each selected concept of operations.Peer ReviewedPostprint (published version

Educational Project for the Teaching of Control of Electric Traction Drives

Electric vehicles constitute a multidisciplinary subject that involves disciplines such as automotive, mechanical, electrical and control engineering. Due to this multidisciplinary technical nature, practical teaching methodologies are of special relevance. Paradoxically, in the past, the training of engineers specializing in this area has lacked the practical component represented by field tests, due to the difficulty of accessing real systems. This paper presents an educational project specifically designed for the teaching and training of engineering students with different backgrounds and experience. The teaching methodology focuses on the topology of electric traction drives and their control. It includes two stages, a simulation computer model and a scaled laboratory workbench that comprises a traction electrical drive coupled to a vehicle emulator. With this equipment, the effectiveness of different traction control strategies can be analyzed from the point of view of energy efficiency, robustness, easiness of implementation and acoustic noise

El objetivo de este trabajo es realizar una comparación entre dos sistemas solares pasivos de ganancia indirecta, el muro de doble piel tipo Trombe y un muro de triple piel concentrando su importancia en la reducción de la demanda de calefacción en un contexto de crisis climática y energética mundial. En primer lugar, ambos muros se caracterizarán térmicamente y se someterán a un análisis de sensibilidad que muestre aquellos parámetros que más influyen en las capacidades de transmitir la energía a los espacios habitables como la de impedir que el calor se pierda al exterior. En segundo lugar, se cuantificará la reducción de la demanda de calefacción para edificios rehabilitados variando el clima, Con los resultados obtenidos, el trabajo permitirá aclarar que solución de sistema solar será más optimo sujeto a las condiciones de los edificios estudiados.The objective of this work is to make a comparison between two indirect gain passive solar systems, the double layer Wall (Trombe wall) and a triple layer wall, concentrating their importance in reducing the demand for heating in a context of global climate and energy crisis. First, both walls will be thermally characterized and will be subjected to a sensitivity analysis that shows those parameters that most influence the ability to transmit energy to living spaces, such as preventing heat from being lost to the outside. Second, the reduction in heating demand for rehabilitated buildings will be quantified by varying the climate. With the results obtained, the work will clarify which solar system solution will be more optimal subject to the conditions of the buildings studied.Universidad de Sevilla.

CARTOGRAFÍAS SUSPENDIDAS. EL ENTORNO COMO ELEMENTO CONFIGURADOR DE LA IDENTIDAD SOCIAL

[EN] The present End of Degree work is the result of theoretical-­‐practical research that deals with some concepts related to social identity and the territorial configuration that stems from them, using cartography as a formal and conceptual organizing element. It is an interdisciplinary artistic project in which artistic practice has been determined by photography as an expressive way to evolve towards an investigation of different languages, both graphic and sculptural, assimilating them and channeling this matter toward other artistic and conceptual aspects. It has been considered the relation of the subjects with their environment from the way they interact with it, building various ways of life that define the formal and visual characteristics of our artistic work. The result is a series of maps developed in different artistic languages that have been realized during this period of formation in the Fine Arts Degree program.[ES] El presente Trabajo de Fin de Grado es el resultado de una investigación teórico-­‐práctica en el que se han abordado conceptos relacionados con la identidad social y la consecuente configuración territorial a partir de ella, utilizando la cartografía como elemento estructurador formal y conceptual. Es un proyecto artístico interdisciplinar en el que la práctica artística desarrollada ha estado marcada, en un inicio, por la fotografía como medio de expresión para evolucionar hacia una investigación de distintos lenguajes gráficos y escultóricos asimilando éstos y encauzando la temática tratada hacia otras vertientes artísticas y conceptuales. Se plantea la relación del sujeto con su entorno a partir de cómo interactúa con éste, construyendo así diversos modos de vida, que definen las características formales y plásticas de nuestro trabajo artístico, dando como resultado una serie de mapas desarrollados en distintos lenguajes artísticos que hemos elaborado durante nuestro periodo de formación en el Grado de Bellas Artes.Pastor Hidalgo, M.

Una introducción a los métodos multigrid

A partir del análisis del suavizado de los métodos de Jacobi y Gauss‐Seidel cuando se aplican a la resolución numérica de un problema de Poisson, se introducirán los métodos multigrid. En concreto se introducirá el ciclo de dos mallas, con la corrección en la malla grosera. El objetivo del trabajo será mostrar cómo la combinación del suavizado y la corrección en malla grosera permite obtener métodos que integran muy eficientemente los sistemas lineales que aparecen al discretizar en espacio problemas elípticos.Departamento de Matemática AplicadaGrado en Matemática
