Estudio de validez del WAsP frente al WindSim en colinas Gaussinas

Este proyecto se basa en la comparación de un modelo de flujo lineal frente a un modelo de ecuaciones completas. Con esta motivación se empleará un programa de cada tipo. Los elegidos son el WAsP y el WindSim respectivamente. Tras una breve descripción de cada programa, estudiaremos los distintos elementos que los componen y su estructura. Entre todas las posibilidades que presentan ambos programas, el proyecto se centrará en la estimación del recurso eólico. En teoría, el programa que emplea un modelo lineal no será apto en terrenos complejos, por ello se tratará de estimar el error cometido por el modelo lineal tomando como referencia el modelo de ecuaciones completas. Con el objetivo de comparar ambos programas y poder distinguir sus diferencias, se plantea un caso común, en el cual se evaluarán distintas condiciones meteorológicas para colinas de forma gaussiana y distinta pendiente. Con ello se pretende medir la evolución de la precisión del WAsP conforme el terreno se va haciendo más complejo. Otras variables a tener en cuenta serán la variación de la velocidad del viento y la altura del punto de cálculo. Finalmente se analizan y explican los resultados obtenidos acompañados de elementos visuales proporcionados por los programas. 2. Abstract The main objective of this project is the comparison of two models, one based on the lineal flux and the other based on the complete equations. Thanks to two different computer programmes, WAsP and WindSim, the first one using a linear model and the second one using a complete equation model, we will be able to highlight the main differences between both models. Furthermore, a description of the structure and elements of each program will be outlined. This project will focus on the estimation of the wind resource. In theory, the program which uses a linear model will not be useful in complex terrains. Therefore, we will try to estimate the fault of the lineal model comparing it to the complete equation model. In order to be able to distinguish the differences between both programmes, the same exercise will be proposed to be solved by both of them. Here a range of meteorological conditions will be evaluated over a Gaussian hill with a slope that varies. Thereby, we will be able to measure the evolution of the precision of WAsP according to the increase of the slope. Finally, the results are analysed and explained with help of some visual characters.

Governance Structure Choices in Supply Chain Management Evidence from Spanish and Chinese Pork Chain Cases

The author participated in the 6 th EU Framework Project ―Q-pork Chains (FP6-036245-2)‖ from 2007 to 2009. With understanding of work reports from China and other countries, it is found that compared with other countries, China has great problems in pork quality and safety. By comparing the pork chain management between China and Spain, It is found that the difference in governance structure is one of the main differences in pork chain management between Spain and China. In China, spot-market relationship still dominates governance structure of pork chain, especially between the numerous house-hold pig holders and the great number of small slaughters. While in Spain, chain agents commonly apply cooperatives or integrations to cooperate. It also has been proven by recent studies, that in quality management at the chain level that supply chain integration has a direct effect on quality management practices (Han, 2010). Therefore, the author started to investigate the governance structure choices in supply chain management. And it has been set as the first research objective, which is to explain the governance structure choices process and the influencing factors in supply chain management, analyzing the pork chains cases in Spain and in China. During the further investigation, the author noticed the international trade of pork between Spain and China is not smooth since the signature of bi-lateral agreement on pork trade in 2007. Thus, another objective of the research is to find and solve the problems exist in the international pork chain between Spain and China. For the first objective, to explain the governance structure choices in supply chain management, the thesis conducts research in three main sections. 10 First of all, the thesis gives a literature overview in chapter two on Supply Chain Management (SCM), agri-food chain management and pork chain management. It concludes that SCM is a systems approach to view the supply chains as a whole, and to manage the total flow of goods inventory from the supplier to the ultimate customer. It includes the bi-directional flow of products (materials and services) and information, and the associated managerial and operational activities. And it also is a customer focus to create unique and individual source of customer value with an appropriate use of resources, leading to customer satisfaction and building competitive chain advantages. Agri-food chain management and pork chain management are applications of SCM in agri-food sector and pork sector respectively. Then, the research gives a comparative study in chapter three in the pork chain and pork chain management between Spain and China. Many differences are found, while the main difference is governance structure in pork chain management. Furthermore, the author gives an empirical study on governance structure choice in chapter five. It is concluded that governance structure of supply chain consists of a collection of rules/institutions/constraints structuring the transactions between the various stakeholders. Based on the overview on literatures closely related with governance structure, such as transaction cost economics, transaction value analysis and resource-based view theories, seven hypotheses are proposed, which are: Hypothesis 1: Transaction cost has positive relationship with governance structure choice Hypothesis 2: Uncertainty has positive relationship with transaction cost; higher uncertainty exerts high transaction cost Hypothesis 3: The relationship between asset specificity and transaction cost is positive Hypothesis 4: Collaboration advantages and governance structure choice have positive relationship11 Hypothesis 5: Willingness to collaborate has positive relationship with collaboration advantages Hypothesis 6: Capability to collaborate has positive relationship with collaboration advantages Hypothesis 7: Uncertainty has negative effect on collaboration advantages It is noted that as transaction cost value is negative, the transaction cost mentioned in the hypotheses is its absolute value. To test the seven hypotheses, Structural Equation Model (SEM) is applied and data collected from 350 pork slaughtering and processing companies in Jiangsu, Shandong and Henan Provinces in China is used. Based on the empirical SEM model and its results, the seven hypotheses are proved. The author generates several conclusions accordingly. It is found that the governance structure choice of the chain not only depends on transaction cost, it also depends on collaboration advantages. Exchange partners establish more stable and more intense relationship to reduce transaction cost and to maximize collaboration advantages. ―Collaboration advantages‖ in this thesis is defined as the joint value achieved through transaction (mutual activities) of agents in supply chains. This value forms as improvements, mainly in mutual logistics systems, cash response, information exchange, technological improvements and innovative improvements and quality management improvements, etc. Governance structure choice is jointly decided by transaction cost and collaboration advantages. Chain agents take different governance structures to coordinate in order to decrease their transaction cost and to increase their collaboration advantages. In China´s pork chain case, spot market relationship dominates the governance structure among the numerous backyard pig farmer and small family slaughterhouse 12 as they are connected by acquaintance relationship and the transaction cost in turn is low. Their relationship is reliable as they know each other in the neighborhood; as a result, spot market relationship is suitable for their exchange. However, the transaction between large-scale slaughtering and processing industries and small-scale pig producers is becoming difficult. The information hold back behavior and hold-up behavior of small-scale pig producers increase transaction cost between them and large-scale slaughtering and processing industries. Thus, through the more intense and stable relationship between processing industries and pig producers, processing industries reduce the transaction cost and improve the collaboration advantages with their chain partners, in which quality and safety collaboration advantages be increased, meaning that processing industries are able to provide consumers products with better quality and higher safety. It is also drawn that transaction cost is influenced mainly by uncertainty and asset specificity, which is in line with new institutional economics theories developed by Williamson O. E. In China´s pork chain case, behavioral uncertainty is created by the hold-up behaviors of great numbers of small pig producers, while big slaughtering and processing industries having strong asset specificity. On the other hand, ―collaboration advantages‖ is influenced by chain agents´ willingness to collaborate and chain agents´ capabilities to cooperate. With the fast growth of big scale slaughtering and processing industries, they are more willing to know and make effort to cooperate with their chain members, and they are more capable to create joint value together with other chain agents. Therefore, they are now the main chain agents who drive more intense and stable governance structure in China‘s pork chain. For the other objective, to find and solve the problems in the international pork chain between Spain and China, the research gives an analysis in chapter four on the 13 international pork chain. This study gives explanations why the international trade of pork between Spain and China is not sufficient from the chain perspective. It is found that the first obstacle is the high quality and safety requirement set by Chinese government. It makes the Spanish companies difficult to get authorities to export. Other aspects, such as Spanish pork is not competitive in price compared with other countries such as Denmark, United States, Canada, etc., Chinese consumers do not have sufficient information on Spanish pork products, are also important reasons that Spain does not export great quantity of pork products to China. It is concluded that China´s government has too much concern on the quality and safety requirements to Spanish pork products, which makes trade difficult to complete. The two countries need to establish a more stable and intense trade relationship. They also should make the information exchange sufficient and efficient and try to break trade barriers. Spanish companies should consider proper price strategies to win the Chinese pork market

Bases territoriales y metodológicas de la planificación para el desarrollo del turismo sustentable en la región de Coquimbo

El proceso de planificación de una u otra forma ha estado implicado en el desarrollo del turismo, aunque su aplicación no ha sido del todo exitosa. Asimismo la revalorización que está teniendo la planificación en distintos ámbitos, público y privado, tampoco es ajena en el turismo, pero, aún requiere modificaciones en los métodos y técnicas para ser aplicada a un turismo sustentable. Las modificaciones en los métodos para la planificación del turismo sustentable en la Región de Coquimbo, constituyen el objeto de esta investigación. La investigación establece como hipótesis: “La integración de las metodologías de planificación con los principios del turismo sustentable permitiría generar un modelo de planificación turística sustentable, que incorpora los valores del territorio, las necesidades de los visitantes, la participación de la comunidad receptora y es aplicable a la Región de Coquimbo a través de un marco territorial-metodológico”. A partir de esta hipótesis, se define el objetivo general: Elaborar una propuesta de un marco territorial-metodológico para la planificación turística sustentable en la Región de Coquimbo. De este objetivo general se deducen los objetivos específicos relacionados con el análisis de los conceptos y enfoques teóricos de la planificación aplicada al turismo; el estudio de los instrumentos de planificación del desarrollo turístico de la Región de Coquimbo; la determinación de categorías y elementos estructurantes y la elaboración de un marco territorial-metodológico de la planificación para el desarrollo del turismo sustentable en la Región de Coquimbo. La metodología de la investigación es de carácter cualitativo, está relacionada principalmente con la teoría fundamentada o grounded theory y con las teorías procedimentales de la planificación. Ambas metodologías fueron utilizadas en la construcción del modelo genérico y en la elaboración del marco procedimental-territorial. La construcción del modelo genérico se asimiló con la de la teoría en la grounded theory y de esta forma, se generaron conceptos a partir del marco conceptual teórico (conceptualización o abstracción); se construyeron categorías de análisis procedimental, territorial y de turismo sustentable (codificación abierta), se elaboraron categorías síntesis procedimental-territoriales y de turismo sustentable (codificación axial); se analizó la dinámica relacional de las categorías procedimental-territoriales (codificación selectiva) y se estableció el modelo genérico de planificación del turismo sustentable (teoría), que cuenta con dos submodelos: el submodelo de Condiciones Generales y el submodelo de Etapas de la planificación. A partir del modelo genérico se jerarquizaron las categorías definidas y relacionadas en forma dinámica, de acuerdo a las características de la Región de Coquimbo. Conjuntamente se incluyeron los requisitos del turismo sustentable recomendados por el Servicio Nacional de Turismo (SERNATUR) a nivel nacional, regional y comunal y se incorporaron las etapas ausentes en los planes de desarrollo turístico formulados en la Región, para dar origen al marco procedimental-territorial aplicado en la Región de Coquimbo. La investigación entrega como resultado una metodología de planificación para el turismo sustentable (modelo genérico), que al aplicarse a un sistema territorial particular, como es la Región de Coquimbo, genera una nueva metodología específica de planificación para el turismo sustentable de esta región (marco procedimental-territorial). El modelo genérico podrá ser aplicable a cualquier territorio dentro o fuera de la Región de Coquimbo, relevando sus propios valores, las necesidades de los visitantes y la participación de la comunidad y generando sus propios marcos procedimentales—territoriales (considerando los rasgos propios de los territorios, los requisitos del turismo sustentable y corrigiendo las falencias de las planificaciones previas existentes en ese territorio particular). ABSTRACT One way or another the process of planning has been implied in the development of tourism, although its application has not been absolutely successful. Also the revaluation that the planning is having in different scopes, public and private, and tourism is not free from it either, but still it requires modifications in the methods and techniques to be applied to a sustainable tourism. The modifications in the methods for the planning of the sustainable tourism in the Region of Coquimbo constitute the object of this investigation. The research establishes as hypothesis: “The integration of planning methodologies with the principles of the sustainable tourism would allow to generate a model of sustainable tourist planning, that incorporates the values of the territory, the needs of the visitors, the participation of the receiving community and is applicable to the Region of Coquimbo through a territorial-methodologic frame”. From this hypothesis, the general objective is defined: To make a proposal of a territorial-methodologic frame for the sustainable tourist planning in the Region of Coquimbo. From this general objective the specific objectives related to the analysis of the concepts and theoretical approaches of the planning applied to the tourism are deduced; the study of the planning tools of the tourist development of the Region of Coquimbo; the determination of categories and structural elements and the elaboration of a territorial-methodologic frame of the planning for the development of the sustainable tourism in the Region of Coquimbo. The methodology of the investigation is of qualitative character, is related mainly to the based theory or grounded theory and to the procedural theories of the planning. Both methodologies were used in the construction of the generic model and in the elaboration of the procedural-territorial frame. The construction of the generic model assimilated with the one of the theory in grounded theory and thus, concepts from the theoretical conceptual frame were generated (conceptualization or abstraction); categories of procedural, territorial analysis were constructed and of sustainable tourism (open codification), procedural-territorial syntheses categories were elaborated and of sustainable tourism (axial codification); the relational dynamics of the procedural-territorial categories was analyzed (selective codification) and the generic model of sustainable tourism planning was established (theory), that counts with two submodels: the General Conditions submodel and the Stages of planning submodel. From the generic model the categories defined and related in dynamic way were hierarchized, according to the characteristics of the Region of Coquimbo. Together with the recommended requirements of sustainable tourism done by The National Service of Tourism (SERNATUR) were included at national, regional level and communal and the absent stages in the formulated plans of tourist development in the Region were included, to give rise to the applied procedural-territorial frame in the Region of Coquimbo. The research gives as a result a planning methodology for sustainable tourism (generic model), that when being applied to a given territorial system, as it is the Region of Coquimbo, it generates a new specific planning methodology for the sustainable tourism of this region (procedural-territorial frame). The generic model could be applicable to any territory inside or outside the Region of Coquimbo, standing out its own values, the needs of the visitors and the participation of the community generating its own procedural-territorial frames (considering the own features of the territories, the requirements of the sustainable tourism and correcting the mistakes of the previous existing planning in that particular territory).

Numerical CFD modelling of non-neutral atmospheric boundary layers for offshore wind resource assessment based on Monin-Obukhov theory

The presented works aim at proposing a methodology for the simulation of offshore wind conditions using CFD. The main objective is the development of a numerical model for the characterization of atmospheric boundary layers of different stability levels, as the most important issue in offshore wind resource assessment. Based on Monin-Obukhov theory, the steady k-ε Standard turbulence model is modified to take into account thermal stratification in the surface layer. The validity of Monin-Obukhov theory in offshore conditions is discussed with an analysis of a three day episode at FINO-1 platform.

Interval-based resource usage verification: Formalization and prototype

In an increasing number of applications (e.g., in embedded, real-time, or mobile systems) it is important or even essential to ensure conformance with respect to a specification expressing resource usages, such as execution time, memory, energy, or user-defined resources. In previous work we have presented a novel framework for data size-aware, static resource usage verification. Specifications can include both lower and upper bound resource usage functions. In order to statically check such specifications, both upper- and lower-bound resource usage functions (on input data sizes) approximating the actual resource usage of the program which are automatically inferred and compared against the specification. The outcome of the static checking of assertions can express intervals for the input data sizes such that a given specification can be proved for some intervals but disproved for others. After an overview of the approach in this paper we provide a number of novel contributions: we present a full formalization, and we report on and provide results from an implementation within the Ciao/CiaoPP framework (which provides a general, unified platform for static and run-time verification, as well as unit testing). We also generalize the checking of assertions to allow preconditions expressing intervals within which the input data size of a program is supposed to lie (i.e., intervals for which each assertion is applicable), and we extend the class of resource usage functions that can be checked.

An approach to automatic learning assessment based on the computational theory of perceptions

E-learning systems output a huge quantity of data on a learning process. However, it takes a lot of specialist human resources to manually process these data and generate an assessment report. Additionally, for formative assessment, the report should state the attainment level of the learning goals defined by the instructor. This paper describes the use of the granular linguistic model of a phenomenon (GLMP) to model the assessment of the learning process and implement the automated generation of an assessment report. GLMP is based on fuzzy logic and the computational theory of perceptions. This technique is useful for implementing complex assessment criteria using inference systems based on linguistic rules. Apart from the grade, the model also generates a detailed natural language progress report on the achieved proficiency level, based exclusively on the objective data gathered from correct and incorrect responses. This is illustrated by applying the model to the assessment of Dijkstra’s algorithm learning using a visual simulation-based graph algorithm learning environment, called GRAPHs

Model-Driven Methodology for Rapid Deployment of Smart Spaces based on Resource-Oriented Architectures

Advances in electronics nowadays facilitate the design of smart spaces based on physical mash-ups of sensor and actuator devices. At the same time, software paradigms such as Internet of Things (IoT) and Web of Things (WoT) are motivating the creation of technology to support the development and deployment of web-enabled embedded sensor and actuator devices with two major objectives: (i) to integrate sensing and actuating functionalities into everyday objects, and (ii) to easily allow a diversity of devices to plug into the Internet. Currently, developers who are applying this Internet-oriented approach need to have solid understanding about specific platforms and web technologies. In order to alleviate this development process, this research proposes a Resource-Oriented and Ontology-Driven Development (ROOD) methodology based on the Model Driven Architecture (MDA). This methodology aims at enabling the development of smart spaces through a set of modeling tools and semantic technologies that support the definition of the smart space and the automatic generation of code at hardware level. ROOD feasibility is demonstrated by building an adaptive health monitoring service for a Smart Gym.

Adaptive control system based on lineal control theory for the path-following problem of a car-like mobile robot

The objective of this paper is to design a path following control system for a car-like mobile robot using classical linear control techniques, so that it adapts on-line to varying conditions during the trajectory following task. The main advantages of the proposed control structure is that well known linear control theory can be applied in calculating the PID controllers to full control requirements, while at the same time it is exible to be applied in non-linear changing conditions of the path following task. For this purpose the Frenet frame kinematic model of the robot is linearised at a varying working point that is calculated as a function of the actual velocity, the path curvature and kinematic parameters of the robot, yielding a transfer function that varies during the trajectory. The proposed controller is formed by a combination of an adaptive PID and a feed-forward controller, which varies accordingly with the working conditions and compensates the non-linearity of the system. The good features and exibility of the proposed control structure have been demonstrated through realistic simulations that include both kinematics and dynamics of the car-like robot.

Data Fusion based on Game Theory for Speaker Diarization

A novel algorithm based on bimatrix game theory has been developed to improve the accuracy and reliability of a speaker diarization system. This algorithm fuses the output data of two open-source speaker diarization programs, LIUM and SHoUT, taking advantage of the best properties of each one. The performance of this new system has been tested by means of audio streams from several movies. From preliminary results on fragments of five movies, improvements of 63% in false alarms and missed speech mistakes have been achieved with respect to LIUM and SHoUT systems working alone. Moreover, we also improve in a 20% the number of recognized speakers, getting close to the real number of speakers in the audio stream

Low-resource language recognition using a fusion of phoneme posteriorgram counts, acoustic and glottal-based i-vectors

This paper presents a description of our system for the Albayzin 2012 LRE competition. One of the main characteristics of this evaluation was the reduced number of available files for training the system, especially for the empty condition where no training data set was provided but only a development set. In addition, the whole database was created from online videos and around one third of the training data was labeled as noisy files. Our primary system was the fusion of three different i-vector based systems: one acoustic system based on MFCCs, a phonotactic system using trigrams of phone-posteriorgram counts, and another acoustic system based on RPLPs that improved robustness against noise. A contrastive system that included new features based on the glottal source was also presented. Official and postevaluation results for all the conditions using the proposed metrics for the evaluation and the Cavg metric are presented in the paper.

The TRANSPLANTA collection of Arabidopsis lines: a resource for functional analysis of transcription factors based on their conditional overexpression.

Los factores de transcripción (FTs) son reguladores clave de la expresión génica en todos los organismos. En eucariotas los FTs con frecuencia están representados por miembros funcionalmente redundantes de familias génicas de gran tamaño. La sobreexpresión de FTs puede representar una herramienta para revelar las funciones biológicas de FTs redundantes en plantas; sin embargo, la sobreexpresión constitutiva de FTs con frecuencia conlleva diversos defectos en el desarrollo, impidiendo su caracterización funcional. Sin embargo, aproximaciones de sobreexpresión condicional podrían ayudar a solventar este problema. En el consorcio TRANSPLANTA, en el que participan varios laboratorios del CBGP, hemos generado una colección de líneas transgénicas de Arabidopsis, cada una de las cuales expresa un FT bajo el control de un promotor inducible por ?estradiol. Hasta el momento se han generado 1636 líneas homocigotas independientes que corresponden a 634 FTs diferentes, lo que representa una media de 2,6 líneas por cada FT. Como confirmación de la utilidad de esta herramienta, el tratamiento con ?estradiol de líneas que expresaban condicionalmente FTs provoca alteraciones fenotípicas tales como proliferación de pelos radiculares, senescencia inducida por oscuridad, acumulación de antocianinas y enanismo, y que corroboran fenotipos previamente descritos debidos a la sobreexpresión de dichos FTs. Rastreos realizados posteriormente con otras líneas TRANSPLANTA han permitido la identificación de FTs implicados en diferentes procesos biológicos de plantas, confirmando que la colección es una herramienta valiosa para la caracterización funcional de FTs. Las semillas de las líneas TRANSPLANTA han sido depositadas en el Nottingham Arabidopsis Stock Centre para su distribución posterior.

Design and analysis of ripple-based controls based on the discrete modeling and Floquet theory

Ripple-based controls can strongly reduce the required output capacitance in PowerSoC converter thanks to a very fast dynamic response. Unfortunately, these controls are prone to sub-harmonic oscillations and several parameters affect the stability of these systems. This paper derives and validates a simulation-based modeling and stability analysis of a closed-loop V 2Ic control applied to a 5 MHz Buck converter using discrete modeling and Floquet theory to predict stability. This allows the derivation of sensitivity analysis to design robust systems. The work is extended to different V 2 architectures using the same methodology.

Application of the agency theory for the analysis of performance-based mechanisms in road management

El WCTR es un congreso de reconocido prestigio internacional en el ámbito de la investigación del transporte, y aunque las actas publicadas están en formato digital y sin ISSN ni ISBN, lo consideramos lo suficientemente importante como para que se considere en los indicadores. This paper develops a model based on agency theory to analyze road management systems (under the different contract forms available today) that employ a mechanism of performance indicators to establish the payment of the agent. The base assumption is that of asymmetric information between the principal (Public Authorities) and the agent (contractor) and the risk aversion of this latter. It is assumed that the principal may only measure the agent?s performance indirectly and by means of certain performance indicators that may be verified by the authorities. In this model there is presumed to be a relation between the efforts made by the agent and the performance level measured by the corresponding indicators, though it is also considered that there may be dispersion between both variables that gives rise to a certain degree of randomness in the contract. An analysis of the optimal contract has been made on the basis of this model and in accordance with a series of parameters that characterize the economic environment and the particular conditions of road infrastructure. As a result of the analysis made, it is considered that an optimal contract should generally combine a fixed component and a payment in accordance with the performance level obtained. The higher the risk aversion of the agent and the greater the marginal cost of public funds, the lower the impact of this performance-based payment. By way of conclusion, the system of performance indicators should be as broad as possible but should not overweight those indicators that encompass greater randomness in their results.

Regret theory-based scenario building using an interacttive process

This paper is an introduction of the regret theory-based scenario building approach combining with a modified Delphi method that uses an interactive process to design and assess four different TDM measures (i.e., cordon toll, parking charge, increased bus frequency and decreased bus fare). The case study of Madrid is used to present the analysis and provide policy recommendations. The new scenario building approach incorporates expert judgement and transport models in an interactive process. It consists of a two-round modified Delphi survey, which was answeared by a group of Spanish transport experts who were the participants of the Transport Engineering Congress (CIT 2012), and an integrated land-use and transport model (LUTI) for Madrid that is called MARS (Metropolitan Activity Relocation Simulator).
