Searching and Classifying Affinities in a Web Music Collection
No full textOnline music libraries available on the Web contain a large amount of audio content that is usually the result of digitization of analogue recordings or the direct acquisition of digital sources. The acquisition process is carried out by several persons and may last a number of years, thus it is likely that the same or similar audio content is present in different versions. This paper describes a number of possible similarities, which are called affinities, and presents a methodology to detect the kind of affinity from the automatic analysis and matching of the audio content
Searching and Exploring Data in a Software Architecture for Film-Induced Tourism
No full textFilm induced tourism is a recent phenomenon, rising increasing interest in tourism management and promotion. A research project on this topic has been recently investigated at the Department of Cultural Heritage of the University of Padua, resulting in the development of a software architecture for the promotion of film-induced tourism, capable of storing and providing rich information about the movies produced in a selected geographic area. This paper presents the design and implementation of the solutions developed to search and explore the data stored in the software architecture
Evaluation of Input Devices for Musical Expression: Borrowing Tools from HCI
No full textThis article addresses the evaluation of input devices for musical expression. The comparison and evaluation of input devices is a well-developed topic in Human-Computer Interaction (HCI) research area, a multidisciplinary field that presents several similarities (and many differences) to computer music. We here introduce an overview of various developments from HCI and discuss possible applications of this knowledge to the musical context. Results from previous experiments are commented and a set of musical tasks is suggested and discussed as a first step toward the evaluation of input devices for musical expression
El proyecto de Luis Tolosa para Nueva Cerámica de Orio, una construcción racionalista
No full textThe intervention project for Nueva Cerámica de Orio (New Ceramic of Orio) designed by Luis Tolosa in 1940 is one of the most recognised rationalist works in the industrial architecture in Gipuzkoa. Its iconic surrounding has made it into an undeniable reference site with a modernity image that industrialists in Gipuzkoa were looking for their factories during the post-war era. Nevertheless, the main achievement of this solution lies in how the project defines a unique answer which comprehends all the productive elements that already existed in the factory. The purpose of this analysis is to study the way Luis Tolosa integrates every pre-existing structure in the new factory, in a single modern building, thanks to the new technique of the reinforced concrete. A structural technology which in his project for the Nueva Cerámica in Orio achieves the required prominence of a real rationalist architecture.El proyecto de intervención para la Nueva Cerámica de Orio, redactado por Luis Tolosa en 1940, es una de las obras racionalistas más reconocidas de la arquitectura industrial guipuzcoana. Su icónica envolvente la ha convertido en referencia indiscutible del tipo de imagen de modernidad que los industriales guipuzcoanos buscaban para sus fábricas durante la posguerra. Sin embargo, el mérito principal de esta solución radica en cómo el proyecto define una respuesta única que engloba todos los elementos productivos preexistentes de la fábrica. El objetivo de este análisis es el de estudiar como Luis Tolosa integra cada una de estas construcciones preexistentes con las de nueva planta, en un edificio unitario moderno, gracias a la nueva técnica del hormigón armado. Una tecnología constructiva que, en su proyecto para la Nueva Cerámica de Orio, adquiere el protagonismo que requiere una verdadera arquitectura racionalista
Optical spectroscopy of novae in M 31
No full textWe report results of a spectrophotometric survey of novae in M 31. The observations were carried out using the TNG at La Palma and the 1.82 m telescope of the INAF/OAPD at Asiago observatory . Low resolution spectra of the novae, obtained mainly in the early decline phase, allow us to classify the objects following the Tololo scheme \citep{1992AJ....104..725W
Alignment of Performances with Scores Aimed at Content-Based Music Access and Retrieval
No full textMusic digital libraries pose interesting and challenging research problems, in particular for the development of methodologies and tools for the retrieval of music documents. One difficult aspect of content-based retrieval of musical works is that only scores can be represented by a symbolic notation, while performances, which are of interest for the majority of users, allow for access based on bibliographic values only. The research work reported in this paper proposes to index and retrieve music performances through an automatic alignment of acoustic recordings with the music scores. Alignment my allow for: automatic recognition of performances, aimed at cataloging large collections of recordings; automatic tagging of performances, aimed at an easy access to long recordings. The methodology is based on the use of hidden Markov models, a powerful tool that has been successfully used in many research areas, like speech recognition and molecular biology. The approach has been tested on a collection of acoustic and synthetic performances, showing good results in the recognition and in the tagging of performances. The proposed approach can be used to increase the functionalities of a music digital library, allowing for content-based access to scores and recordings
