Adaptive tuning system and parameter estimation of a digitally controlled boost converter with STM32
2019
. This paper proposes a diagnostic system of a power electronic converter, based on a cheap STM32 Nucleo board, aiming to extract some relevant measurements which gives back important values of the converter's parameters behavior. Moreover the designed system is also exploited for implementing the converter's auto tuning in order to optimize its dynamic performance.
A Musical Pattern Discovery System Founded on a Modeling of Listening Strategies
2004
Music is a domain of expression that conveys a paramount degree of complexity. The musical surface, composed of a multitude of notes, results from the elaboration of numerous structures of different types and sizes. The composer constructs this structural complexity in a more or less explicit way. The listener, faced by such a complex phenomenon, is able to reconstruct only a limited part of it, mostly in a non-explicit way. One particular aim of music analysis is to objectify such complexity, thus offering to the listener a tool for enriching the appreciation of music (Lartillot and SaintJames, 2004). The trouble is, traditional musical analysis, although offering a valuable understanding …
Tempo Induction from Music Recordings Using Ensemble Empirical Mode Decomposition Analysis
2011
Tempo and beat are among the most important features of Western music. Owing to the perceptual nature of tempo, its automatic analysis and extraction remains a difficult task for a large variety of music genres. Western music notation represents musical events using a hierarchical metrical structure distinguishing different time scales. This hierarchy is often modeled using three levels: the tatum, the tactus, and the measure. The tatum represents the shortest durational value in music that is not just an accidental phenomenon (Bilmes 1993). The tactus period is the most perceptually prominent period, and is the period at which most humans would tap their feet in time with the music (Lerdah…
Semantic models of musical mood: Comparison between crowd-sourced and curated editorial tags
2013
Social media services such as Last.fm provide crowd-sourced mood tags which are a rich but often noisy source of information. In contrast, editorial annotations from production music libraries are meant to be incisive in nature. We compare the efficiency of these two data sources in capturing semantic information on mood expressed by music. First, a semantic computing technique devised for mood-related tags in large datasets is applied to Last.fm and I Like Music (ILM) corpora separately (250,000 tracks each). The resulting semantic estimates are then correlated with listener ratings of arousal, valence and tension. High correlations (Spearman's rho) are found between the track positions in…
Further Investigation of Harmonic Priming in Long Contexts Using Musical Timbre as Surface Marker to Control for Temporal Effects
2004
Harmonic priming studies have reported facilitated processing for chords that are harmonically related to the prime context. Responses to the target (the last chord of an 8-chord sequence) were faster and more accurate when the target was strongly related, i.e., a tonic chord, to the preceding prime context than when it was less related, i.e., a subdominant chord. Results have been interpreted in terms of musical expectations and processing speed: the prime allows listeners to develop expectations for future events which lead to facilitated processing of the most strongly expected event. The present experiment investigated an alternative hypothesis suggesting that the harmonic structure of…
Suono e corpo. Parametrizzazione dei processi performativi, articolazioni sonore e contagio esperienziale nella proposta musicale di Dario Buccino
2022
Il contributo prende in esame la singolare ricerca performativo-sonora del compositore Dario Buccino (Roma, 1968), la profonde implicazioni esistenziali della sua poetica, il sitema di notazione non convenzionale da lui messo a punto e le tappe fondamentali del suo itinerario creativo dagli anni Novanta a oggi.
Tradition and modernity: new sound proposals from the music schools of the federation of musical societies of the valencian community
2019
Background: The Federation of Musical Societies of the Valencian Community (FSMCV) is a democratic association created 50 years ago, which represents and supports the 550 associations that make it up, with the aim of promoting, disseminating and teaching music. It promotes associationism and provides society with a way of developing cultural articulation, mainly developing its activities within the Valencian Community, although its national and international activity is very remarkable. Methodology: This article based on a prospective study using a qualitative methodology analyzes one of the proposals made to commemorate the 50th anniversary of the FSMCV through the use and application of t…
Categories, Musical Instruments, and Drawings: A Unification Dream
2019
The mathematical formalism of category theory allows to investigate musical structures at both low and high levels, performance practice (with musical gestures) and music analysis. Mathematical formalism can also be used to connect music with other disciplines such as visual arts. In our analysis, we extend former studies on category theory applied to musical gestures, including musical instruments and playing techniques. Some basic concepts of categories may help navigate within the complexity of several branches of contemporary music research, giving it a unitarian character. Such a 'unification dream,' that we can call 'cARTegory theory,' also includes metaphorical references to topos th…
Política del ruido. En los límites de la comunicación musical
2016
Este artículo se basa en la idea de cómo la comunicación musical activa no solo elementos musicales sino culturales y sociales. Como práctica social, la música muestra tanto su poder comunicativo como los límites de la comunicación (entendida como un intercambio de mensajes y significados). En este sentido, el ruido se presenta como un factor de disrupción en el circuito semiótico y en las relaciones sociales. La cuestión del ruido se trata como un aspecto liminar del sonido y la música, como puede observarse en diversos ejemplos tomados de la vanguardia (ruidismo) hasta la música popular contemporánea (noise), pasando por géneros musicales particulares como el punk-rock o la música tecno.
