Simulation of Dynamic Thermal Behaviour for Housing in Warm Climate: The Case of Thermal Mass in Lightweight Envelopes
No full textComparison between simulation results and measured performances is usually an open scientific problem, crucial to achieving the goal of NZEB performance.
This paper addresses this issue in relation to residential buildings, using as a case study “RhOME for denCity”, the housing prototype developed by Roma TRE University and winner of Solar Decathlon Europe 2014.
In a Mediterranean climate, the use of the mass combined with natural cross ventilation to control the indoor microclimate can be very effective in reducing HVAC use. Therefore, a “massive layer” was introduced in the inner surface of the envelope to not only contribute to the envelope transmittance value and the shifting phase of the thermal waves, but also as a thermal shock absorber to adjust the internal temperature, in both summer and winter.
This experimental envelope was tested over two weeks during the competition in Versailles. Although prototype thermal behaviour was monitored only during the competition, and not over an extended period, initial results provide information on how to size the thermal mass contribution for indoor comfort. In-depth simulation through TRNSYS was run prior to the construction phase. This paper presents the comparison between monitored performance and simulations in order to measure the amount of mass needed to obtain a numerical improvement in indoor comfort performance

Requisiti minimi per risposte abitative essenziali di natura temporanea: contributo tecnologico al framework di resilienza.
No full textLa pressione demografica, dovuta a migrazioni e inurbamento massivo nelle megacity, determina un disagio abitativo che in assenza di risposte rapide della programmazione urbanistica tradizionale, comporta una sempre maggiore emergenza abitativa che si traduce in risposte informali autogestite che diventano, esse stesse, emergenza.
La città è chiamata a far fronte a questo stress cronico, aumentando la propria attitudine alla resilienza e operando una pianificazione preventiva di risposte abitative, rapide e a basso costo, che esulino da soluzioni emergenziali e dal consumo di suolo extraurbano.
Attraverso una metodologia complessa, basata sull’analisi di insediamenti informali, e di Casi Studio progettati come prevenzione ad essi, il presente contributo, frutto di una tesi di dottorato, indaga su quale apporto possa dare l’architettura alla resilienza e se esistano caratteri connotanti - tecnologici, tipologici, funzionali, procedurali - che, applicati preventivamente al progetto, possano coadiuvare risposte affini a processi resilienti. Si presenta quindi a livello metaprogettuale un “Framework di indicazioni tecniche di una risposta abitativa essenziale, di nuova costruzione e di natura temporanea”, strutturato in “Schede Tecniche per la Progettazione”, con indicazioni progettuali e procedurali, volto ad essere di ausilio agli attori coinvolti in processi progettuali, dagli esiti resilienti
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
