ON THE SUSTAINABILITY OF NOISE MITIGATION MEASURES
No full textIn recent years, the issue of sustainability has assumed great importance in every field, including noise mitigation measures, and interested stakeholders have found themselves struggling with still evolving and uncertain techniques to evaluate the related social, economic, and environmental aspects. Indeed, the sustainability assessment can be accomplished with many different methods and countless indicators. To clarify the problem and identify suitable methodologies to assess the sustainability of noise mitigation solutions for roads, the Italian PIARC committee TC 3.4.2 has undertaken an in-depth study on the most ascertained techniques, from Life Cycle Sustainability Assessment to the more recent Envision protocol. This study has involved a broad and focused effort to define the meaning of sustainability, from the perspective of infrastructure managers, users, and the general population. Criteria and indicators to describe the performance of noise mitigation solutions have been identified and a general procedure for assessing the sustainability of noise mitigation measures has been defined. The selected method and indicators have then been applied to a case study, located in a suburban environment, to test their applicability and reliability. In this paper, the main outcomes of this study are reported

The LIFE SILENT Project's approach to sustainable noise mitigation
No full textThe main objective of the LIFE SILENT project is the development of sustainable and eco-friendly solutions to mitigate noise in complex urban environments, where multiple and diverse noise sources, mainly roads and railways, coexist across densely populated areas. Mitigating noise in such environments generally excludes the use of solutions that might interfere with the urban context, such as high noise barriers. This is mainly due to the proximity of receivers to the noise source, which reduces the visibility of the surroundings and air circulation, leading to microclimatic modifications and social opposition. This is why noise mitigation measures acting directly on the source are recommended, such as low-noise pavements for roads, and dampers, rail grinding, and silent brakes for railways. However, these solutions suffer from either durability issues or high implementation costs. Thus, an improvement is necessary. In the LIFE SILENT project, innovative and sustainable low-noise and long-lasting pavements, as well as low-height noise barriers, will be developed and demonstrated in a real test environment. Additionally, procedures will be established to facilitate their synergistic implementation, providing transport infrastructure owners and managers with solid information to support their widespread adoption. In this paper, a general overview of the LIFE SILENT project is given
Variations on the Author
No full text“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

Rilievo 3D per la prototipazione virtuale e fisica di reperti per la conservazione del cibo: due casi di studio
No full textIn questo lavoro viene descritto, attraverso l’impiego di tecnologie innovative, il processo di rilievo 3D di due interessanti casi di studio, attualmente non integri, insieme alle successive fasi di prototipazione virtuale e fisica di alcune ipotesi di restauro per restituirne la forma originaria “ideale”. Il lavoro è stato condotto, a titolo esemplificativo, dal Laboratorio di ArcheoIngegneria CAILab della II Facoltà di Ingegneria dell’Università di Bologna in occasione della Mostra “Conservare il cibo da Columella ad Artusi. I luoghi della conservazione” (Castello di Cusercoli – Civitella di Romagna (FC) dal 3 ottobre 2009 al 6 gennaio 2010
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
