Climate models for the assessment of office buildings energy performance
No full textIn the last few years many advanced computer packages, characterised by a considerable integration between thermal and visual aspects, were developed to support designers and to study building energy performance, innovative materials and daylight control strategies and systems. These packages, as a function oftheir complexity and 3nal use, require di5erent types ofoutdoor data, ranging from monthly (MTD) or seasonal typical days (STD) to more complex typical meteorological years (TMY).
Both the deterministic and the stochastic components ofoutdoor data are present in TMYs, while MTDs and STDs take into account
only the deterministic component. The use ofMTDs or STDs produces a sensible reduction ofthe calculation time, above all appreciable in the 3rst phase ofthe building design process, although it introduces an element ofuncertainty in simulation results due to the absence ofthe stochastic component ofoutdoor data. This uncertainty is not easily predictable, as reported by many authors.
The aim ofthe present work is to investigate the in9uence ofthe stochastic component ofmeteorological data in evaluating o"ce
building energy performance in Mediterranean climate. The study is performed by an advanced numerical computer package, Integrated ENergy Use Simulation (IENUS), which can process di5erent types ofclimatic data. Di5erent typologies, systems and space managements are investigated
Lighting distribution affects pedestrians' sense of security
No full textThe greatest obstacle to a pedestrian's Sense of Security (SoS) is lack of lighting. This research analyzes lighting characteristics which affect a pedestrian's SoS, including how lighting distribution changes perception, to design lighting for night-time walking that maximizes the SoS without increasing energy consumption
Smart city roadway lighting system evaluation from driver's field of view
No full textThe latest Smart City roadway lighting technologies and their implementation in cities are being promoted as positive impacts on the quality of life within urban areas along with a sense of safety and security for drivers and pedestrians. Autonomous vehicles are a new addition to this complexity of infrastructure. This paper introduces a new methodology in the evaluation of Smart City lighting from the driver's field of view, and provides latest measured and simulated data that demonstrates the impact of roadway lighting on the driver's vision using 'Adaptation Luminance' function. The results show the drivers' eye adaptation luminance under dynamics of the roadway lighting conditions and reactions to technological innovation in vehicle design while adjusting to Smart City lighting conditions. Solutions aimed at removing the driver from routine operational decision-making are presented, while considering the street lighting design of the future along with in-vehicle lighting conditions
Italian research on eco efficient housing modules
No full textThe theme of the eco- efficient houses is now highly topical in Italy. Universities and companies specialized in sustainable construction are developing projects of experimental buildings that may constitute a typological and constructive reference and may offer the opportunity to monitor their physical and technical performance in order to check the expected theoretical results, the environmental quality and the energy efficiency. To focus on which are the main fields of research in Italy and assess their progress, may be useful to carry out a survey and a comparison between the main development experiences related to the topic of experimental modules and prototypes. The paper analyses and highlights the common features of the last and more significant Italian examples. It also describes technological solutions, materials and energy strategies used in the analyzed experimental buildings, and finally focuses on the main future developments that are involved in Italian research and experimentations on eco-efficient housing units

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
