Virtual restoration of the sound of the Hispanic Rite

The virtual acoustic reality techniques are powerful tools for the recovery of acoustical heritage of historic buildings. Through the acoustic modeling and auralization techniques it´s possible to reconstruct the sound of disappeared buildings or the ones with significant modifications over the years, knowing the original geometry and the acoustic characteristics of their surfaces. This paper shows the results of a research project whose goal is the virtual recovery of the sound of the Hispanic Rite, the rite celebrated by Christians of the Iberian Peninsula before the imposition of the Roman Rite in the mid-eleventh century. For this purpose, acoustic models of a series of Pre-Romanesque churches were made. These acoustic models represent the churches in their original state, following the reconstruction hypothesis proposed by leading researchers in medieval liturgical archeology. Multichannel anechoic recordings of several pieces of the music of the Hispanic Rite have been carried out using a spherical array composed of 31 microphones. Finally, static and dynamic auralizations have been developed, involving the different liturgical configurations which were usual in this rite.

Virtual reconstruction of the 400 toneladas nao from Diego García de Palacio’s Instrucción náutica (1587)

The period between 1570-1620 has left a remarkable amount of documents related to shipbuilding in the Iberian Peninsula. Among them, the Instrucción nautica written by Diego García de Palacio in 1587 is widely recognized as the first published book that includes an extensive discussion of ship design and construction. García de Palacio centres his discussion on a 400 toneladas nao, a series of woodcuts that illustrate the shape and dimensions of the ship accompany the explanation. In the late XVI century ship hulls were designed following procedures based upon an old shipwrightry tradition born in the Mediterranean. By simple rules the master shipwright plots the central frame and tail frames and complete the hull body using wooden ribbands. Computer software for 3D modelling using NURBs surfaces helps to recreate ships hulls. In this work the 400 toneladas nao is reconstructed and her hydrostatic parameters are compared with other ships.

Building lean thinking in a telecom software development organization: strengths and challenges.

The potential shown by Lean in different domains has aroused interest in the software industry. However, it remains unclear how Lean can be effectively applied in a domain such as software development that is fundamentally different from manufacturing. This study explores how Lean principles are implemented in software development companies and the challenges that arise when applying Lean Software Development. For that, a case study was conducted at Ericsson R&D Finland, which successfully adopted Scrum in 2009 and subsequently started a comprehensible transition to Lean in 2010. Focus groups were conducted with company representatives to help devise a questionnaire supporting the creation of a Lean mindset in the company (Team Amplifier). Afterwards, the questionnaire was used in 16 teams based in Finland, Hungary and China to evaluate the status of the transformation. By using Lean thinking, Ericsson R&D Finland has made important improvements to the quality of its products, customer satisfaction and transparency within the organization. Moreover, build times have been reduced over ten times and the number of commits per day has increased roughly five times.The study makes two main contributions to research. First, the main factors that have enabled Ericsson R&D?s achievements are analysed. Elements such as ?network of product owners?, ?continuous integration?, ?work in progress limits? and ?communities of practice? have been identified as being of fundamental importance. Second, three categories of challenges in using Lean Software Development were identified: ?achieving flow?, ?transparency? and ?creating a learning culture?

Migration to an a on-line laboatory in mechanical engineering. The case of a cam-follower design practice.

The European Higher Education Area (EHEA) has leaded to a change in the way the subjects are taught. One of the more important aspects of the EHEA is to support the autonomous study of the students. Taking into account this new approach, the virtual laboratory of the subject Mechanisms of the Aeronautical studies at the Technical University of Madrid is being migrated to an on-line scheme. This virtual laboratory consist on two practices: the design of cam-follower mechanisms and the design of trains of gears. Both practices are software applications that, in the current situation, need to be installed on each computer and the students carry out the practice at the computer classroom of the school under the supervision of a teacher. During this year the design of cam-follower mechanisms practice has been moved to a web application using Java and the Google Development Toolkit. In this practice the students has to design and study the running of a cam to perform a specific displacement diagram with a selected follower taking into account that the mechanism must be able to work properly at high speed regime. The practice has maintained its objectives in the new platform but to take advantage of the new methodology and try to avoid the inconveniences that the previous version had shown. Once the new practice has been ready, a pilot study has been carried out to compare both approaches: on-line and in-lab. This paper shows the adaptation of the cam and follower practice to an on-line methodology. Both practices are described and the changes that has been done to the initial one are shown. They are compared and the weak and strong points of each one are analyzed. Finally we explain the pilot study carried out, the students impression and the results obtained.

Blogs: On the Cutting Edge of the Next-generation Web

This article analyses a number of social and cultural aspects of the blog phenomenon with the methodological aid of a complexity model, the New Techno-social Environment (hereinafter also referred to by its Spanish acronym, NET, or Nuevo Entorno Tecnosocial) together with the socio-technical approach of the two blogologist authors. Both authors are researchers interested in the new reality of the Digital Universal Network (DUN). After a review of some basic definitions, the article moves on to highlight some key characteristics of an emerging blog culture and relates them to the properties of the NET. Then, after a brief practical parenthesis for people entering the blogosphere for the first time, we present some reflections on blogs as an evolution of virtual communities and on the changes experienced by the inhabitants of the infocity emerging from within the NET. The article concludes with a somewhat disturbing question; whether among these changes there might not be a gradual transformation of the structure and form of human intelligence.

Visualization of a student predictive model for 3D virtual environments driven to procedural training

This document presents theimplementation ofa Student Behavior Predictor Viewer(SBPV)for a student predictive model. The student predictive model is part of an intelligent tutoring system, and is built from logs of students’ behaviors in the “Virtual Laboratory of Agroforestry Biotechnology”implemented in a previous work.The SBPVis a tool for visualizing a 2D graphical representationof the extended automaton associated with any of the clusters ofthe student predictive model. Apart from visualizing the extended automaton, the SBPV supports the navigation across the automaton by means of desktop devices. More precisely, the SBPV allows user to move through the automaton, to zoom in/out the graphic or to locate a given state. In addition, the SBPV also allows user to modify the default layout of the automaton on the screen by changing the position of the states by means of the mouse. To developthe SBPV, a web applicationwas designedand implementedrelying on HTML5, JavaScript and C#.

Especificación del comportamiento de un avatar en un mundo virtual mediante una ontología

El presente trabajo describe la construcción de una aplicación que controla a un Non Player Character (NPC), en un mundo virtual. La aplicación desarrollada, que tiene como nombre BotManager, realiza dos tareas fundamentales: 1) conectarse al repositorio de conocimiento, que en esta implementación es una ontología expresada en OWL, para obtener las acciones que debe realizar el NPC dentro del mundo virtual; y 2) ordenar al NPC que realice estas acciones en un mundo virtual creado con la plataforma OpenSimulator. BotManager puede tener variadas aplicaciones, por lo tanto puede ser usada como complemento en mundos virtuales aplicados a la educación, simulación, ocio, etc. Ahora bien, la principal razón que motivó el desarrollo del BotManager fue la de crear un sistema de demostración automática de tareas en un mundo virtual destinado a la educación/ entrenamiento. De esta forma, un Sistema Inteligente de Tutoría integrado con un mundo virtual podría demostrar paso a paso a un estudiante cómo realizar una tarea en el mundo virtual. La ontología que lee el BotManager extiende la ontología propuesta en la tesis “Una propuesta de modelado del estudiante basada en ontologías y diagnóstico pedagógico-cognitivo no monótono” de Julia Parraga en el 2011 (Ontología de Julia). La construcción y las pruebas del BotManager se llevaron a cabo en tres etapas: 1) creación de la Ontología de Acciones del NPC que extiende la Ontología de Julia; 2) diseño e implementación de la aplicación en C# que lee la ontología que contiene el plan de acción del NPC, y ordena al NPC realizar las acciones en el mundo virtual; y 3) pruebas de la aplicación con la práctica “preparación de una taza de cafe”, que es parte de un Laboratorio Virtual de Biotecnología. El BotManager se ha diseñado como una aplicación cliente que se conecta a un servidor de Open- Simulator. Por lo tanto, puede ejecutarse en una máquina distinta a la del servidor. Asimismo, en la implementación del BotManager se ha utilizado una librería gratuita denominada LibOpenMetaverse que permite controlar un NPC de forma remota.---ABSTRACT---This paper describes the construction of an application that controls a Non Player Character (NPC), in a virtual world. The application developed, called BotManager, performs two main tasks: 1) the connection to the repository of knowledge, which in this implementation is an ontology expressed in OWL, and retrieving the actions to be performed by the NPC within the virtual world; and 2) commanding the NPC to perform these actions in a virtual world created with the OpenSimulator platform. BotManager can have diverse applications, therefore it can be used as a complement in virtual worlds applied to education, simulation, entertainment, etc. However, the main reason behind the development of BotManager was to create an automatic demonstration of tasks in a virtual world for education / training. Thus, a virtual world integrated with an Intelligent Tutoring Systems could demonstrate step by step to a student how to perform a task in the virtual world. The ontology used by the BotManager extends ontology proposed in the thesis “A proposal for modeling ontologies based student and not monotonous teaching-cognitive diagnosis” by Julia Parraga in 2011 (Julia’s Ontology). Construction and testing of BotManager were conducted in three stages: 1) creation of the NPC Actions Ontology by extending the Julia’s Ontology; 2) design and implementation of the application in C# that reads the ontology containing the plan of action of the NPC, and commands the NPC to perform the read plan in the virtual world; and 3) testing of the application with the practice “preparing a cup of coffee”, which is part of a Virtual Laboratory of Biotechnology. The BotManager has been designed as a client application that connects to an OpenSimulator server. Therefore, it can run on a different machine to the server. To implement the BotManager we have used a free library called libopenmetaverse that allows us to control a NPC remotely.
