La casa romana. Nella storia della città dalle origini all'Ottocento.
No full textIl testo ripercorre la stoeria della città di Roma attraverso lo studio sistematico dell'assetto urbano, dei tessuti edilizi e delle case che, dall'antichità all'Ottocento, i romani hanno prodotto vivendo in questo luogo. Attraverso i numerosi doumenti d'archivio si è ricostruita la fisionomia e la costruzione fisica della città
Experimental evaluation of noise propagation through rectangular ducts in HVAC system
No full textSound propagation through a rectangular duct of an HVAC system has been investigated in an experimental set-up, in order to evaluate the sound attenuation through different components and the self-noise generated by the airflow. Acoustic and vibration measurements inside the duct were carried out in order to correlate different aspects of noise reduction. The attenuation effects of rectangular straight ducts and of bend ducts with different flow velocities have been evaluated and compared with theoretical formulations
The European qualification system for road traffic noise reducing devices
No full textThe European qualification system for traffic noise reducing devices (NRD's) is based on an advanced framework work of ten standards. This framework is based on a "product standard" (EN 14388) which specifies the performance requirements in terms of measurable characteristics and associated test methods. Each characteristic is rated according to as system of "classes"; for this purpose, a normalised road traffic noise spectrum has been defined (EN 1793-3). Sound absorption and airborne sound insulation must be tested in laboratory using methods which can be regarded as tuned versions of the ISO 354 and ISO 140-3 ones (EN 1793-1 and 2). The same properties can also be measured in situ on installed NRD's, following a new voluntary standard (ENV 1793-5), based on an impulsive technique with the use of a MLS test signal. A similar technique can also be applied to characterise sound diffraction of "added devices" placed on the top of NRD's (ENV 1793-4). Two standards are devoted to non-acoustic performances, such as mechanical stability, fire resistance, etc. (EN 1794-1 and 2). Finally, specific standards deal with long term durability of acoustic and non acoustic characteristics (EN 14389-1 and 2)

Going Beyond Counting First Authors in Author Co-citation Analysis
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
