Discovery of repeated vocal patterns in polyphonic audio: A case study on flamenco music

This paper presents a method for the discovery of repeated vocal patterns directly from music recordings. At a first stage, a voice detection algorithm provides a rough segmentation of the recording to vocal parts, based on which an estimate of the average pattern duration is computed. Then, a pattern detector which employs a sequence alignment algorithm is used to yield a ranking of pairs of matches of the detected voiced segments. At a last stage, a clustering algorithm produces the final repeated patterns. Our method was evaluated in the context of flamenco music for which symbolic metadata are very hard to produce, yielding very promising results.

ANALISIS DE LA MOVILIDAD EN CAMPUS UNIVERSITARIOS INTEGRADOS EN ZONAS URBANAS

Urban transport studies have been characterized by focusing on the analysis of mobility problems between different areas, mainly minimizing travel time. In recent years, negative effects (externalities) of urban mobility are become very important such as environmental aspects. Mobility to campus universities involves up to 10% of journeys made within the city. In this study, the mobility patterns of students, workers and residents in an urban campus are described. It concludes with an assessment of energy consumption and pollutant emissions emitted into the atmosphere, caused by these movements, and thus have a higher level of awareness of the environment damage. The main conclusions of this work are that for environmental pollution reduction, the use of public bicycle service is one of the most effective ways to reduce the private vehicle routes. Likewise parking management must be other measures to be applied, since having a larger number of parking spaces available produces a call effect for private vehicle. Finally, we must promote public transport, by reducing cost and incorporating some incentives for people related to the Campus.
