Catalogador de música MP3 y reproductor de música vía Web con búsquedas de música basadas en la definición de unas observaciones y emociones personales

El principal objetivo del proyecto es romper las fronteras de las búsquedas de canciones en las discotecas de los usuarios domésticos guardadas en los discos duros de sus PC's. Se pretende buscar canciones en base a unas observaciones personales (amigos, lugares, comentarios...) que habrán sido definidas previamente por el usuario, y el segundo tipo buscará canciones en base a las "emociones personales" que también serán definidas por el usuario. Como objetivos secundarios se plantea organizar automáticamente los archivos de audio MP3 almacenados en los ordenadores personales, reproducir los archivos de audio MP3 mediante streaming, un servicio que buscará enlaces web que contengan información/noticias de artistas álbumes, etc., y una agenda musical en la cual los usuarios podrán programar el aviso de observaciones personales

Designing context-aware adaptive units of learning based on IMS-LD standard

Learning contents adaptation has been a subject of interest in the research area of the adaptive hypermedia systems. Defining which variables and which standards can be considered to model adaptive content delivery processes is one of the main challenges in pedagogical design over e-learning environments. In this paper some specifications, architectures and technologies that can be used in contents adaptation processes considering characteristics of the context are described and a proposal to integrate some of these characteristics in the design of units of learning using adaptation conditions in a structure of IMS-Learning Design (IMS-LD) is presented. The key contribution of this work is the generation of instructional designs considering the context, which can be used in Learning Management Systems (LMSs) and diverse mobile devices

A new optimised De Bruijn coding strategy for structured light patterns

Coded structured light is an optical technique based on active stereovision that obtains the shape of objects. One shot techniques are based on projecting a unique light pattern with an LCD projector so that grabbing an image with a camera, a large number of correspondences can be obtained. Then, a 3D reconstruction of the illuminated object can be recovered by means of triangulation. The most used strategy to encode one-shot patterns is based on De Bruijn sequences. In This work a new way to design patterns using this type of sequences is presented. The new coding strategy minimises the number of required colours and maximises both the resolution and the accuracy

El Secuenciador de audio-midi: la "navaja suiza" de la didáctica de la música

El uso de la tecnología musical en el aula es fruto de múltiples investigaciones alrededor del mundo. El objetivo de este taller es mostrar las inmensas posibilidades didácticas de un tipo de software que no está inicialmente diseñado para la educación musical: el Secuenciador de Audio-MIDI. Un Secuenciador2 de Audio-MIDI es un tipo de software musical que puede grabar y gestionar información musical en, generalmente, dos soportes: el MIDI y el audio digital. El uso combinado de estas dos posibilidades más un interface gráfico altamente moldeable, hacen del Secuenciador una potente herramienta musical

OpenSearch-geo: the simple standard for geographic web search engines

When publishing information on the web, one expects it to reach all the people that could be interested in. This is mainly achieved with general purpose indexing and search engines like Google which is the most used today. In the particular case of geographic information (GI) domain, exposing content to mainstream search engines is a complex task that needs specific actions. In many occasions it is convenient to provide a web site with a specially tailored search engine. Such is the case for on-line dictionaries (wikipedia, wordreference), stores (amazon, ebay), and generally all those holding thematic databases. Due to proliferation of these engines, A9.com proposed a standard interface called OpenSearch, used by modern web browsers to manage custom search engines. Geographic information can also benefit from the use of specific search engines. We can distinguish between two main approaches in GI retrieval information efforts: Classical OGC standardization on one hand (CSW, WFS filters), which are very complex for the mainstream user, and on the other hand the neogeographer’s approach, usually in the form of specific APIs lacking a common query interface and standard geographic formats. A draft ‘geo’ extension for OpenSearch has been proposed. It adds geographic filtering for queries and recommends a set of simple standard response geographic formats, such as KML, Atom and GeoRSS. This proposal enables standardization while keeping simplicity, thus covering a wide range of use cases, in both OGC and the neogeography paradigms. In this article we will analyze the OpenSearch geo extension in detail and its use cases, demonstrating its applicability to both the SDI and the geoweb. Open source implementations will be presented as well
