Development of a 0D multi-zone model for fast and accurate prediction of homogeneous charge compression ignition (HCCI) engine
No full textHomogeneous Charge Compression Ignition (HCCI) is a
promising advanced combustion mode, featured by both high thermal
efficiency and low emissions. In this context, a 0D multi-zone model has
been developed, where the thermal stratification in the combustion
chamber has been taken into account. The model is based on a control
mass Lagrangian multi-zone approach. In addition, a procedure based on a
tabulated approach (Tabulated Kinetic of Ignition - TKI) has been
developed, to perform an accurate and fast prediction of the air/fuel
mixture auto-ignition. This methodology allows combining the accuracy of
detailed chemistry with a negligible computational effort. The tabulated
procedure has been preliminarily verified through the comparison with the
results of a commercial software (GT-PowerTM). In this assessment, single
zone simulations have been performed comparing the TKI strategy to a
conventional chemical kinetics one, in four different cases at varying the
intake temperature and the equivalence ratio. Then, the proposed 0D multi-zone
model has been validated against experimental data available in the
literature. The analyses are carried out with reference to an HCCI engine
fuelled with pure hydrogen and working in a single operating point,
namely 1500 rpm, 2.2 bar IMEP and with a fuel/air equivalence ratio of
0.24. Three different temperatures, i.e., 373, 383, and 393 K, have been
considered for the intake air. The experimental/numerical comparisons of
pressure cycles and burn rates proved that the proposed numerical
approach can reproduce the experiments with good accuracy, without the
need for case-by-case tuning

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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
