Sound absorption characterisation of woven materials. Case study: auditorium restoration
No full textExperimental characterisation of woven materials as an absorbing multilayer system for pavements
No full textThe project of the acoustic restoration of an historical conference hall, approved by the Ministry of Italian Cultural Heritage, authorised only the application of woven materials, easy to be removed and not modifying the architectonical characteristics of the hall. This case study allowed the opportunity of investigating the acoustical property of woven materials for pavement and walls. In this paper 12 different samples of carpet have been experimentally investigated by means of the impedance tube method. The effect of the thickness and composition has been analysed and the best absorption sample has been identified. In addition, since textile materials present a good sound absorption, mainly at high frequencies, but not sufficient at low frequency, a multilayer system has been proposed. With the double aim of protecting the existing marble floor and of improving acoustical properties at low frequencies a two - layers system, composed of carpet and felt, has been considered. Two different thicknesses of felt have been tested and the optimal two - layers configuration has been outlined

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
