A Simulation Model for Building Occupancy Prediction
No full textAt present, few computational methods exist that support architect in predicting how their design will be used and experience after its construction. The research described here aims at establishing a new approach for the computational simulation of building occupancy, focused on a clear definition of use scenarios as specific structures of active entities called Events. They allow the formalization of parts of building use process in terms of Actors involved, Activities performed and Space where these events takes place. This modeling framework is functional to simulation environment, where scripted building use process is effectively computed and simulated
Un modello simulativo per la predizione dell’uso di un edificio
No full textPoche tecniche informatiche sono oggi in grado di supportare il difficile compito di prevedere come il risultato del progetto – l’edificio- sarà utilizzato dopo la sua costruzione. La presente ricerca ha lo scopo di definire un nuovo approccio per la simulazione informatica dell’uso di un edificio, basato su una formalizzazione di scenari d’uso attraverso entità computazionali attive definite Eventi. Esse permettono la “discretizzazione” del processo d’uso di un edificio in termini di Attori, Attività e Spazi. Tale modellazione è funzionale all’ambiente di simulazione, dove i processi d’uso dell’edificio così costruiti sono computati e simulati
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Multi-Agent Modelling and Simulation of Hospital Acquired Infection Propagation Dynamics by Contact Transmission in Hospital Wards
No full textHospital-acquired infections (HAI) are recognized worldwide as a major threat to hospital users. In this study, we present the Multi-Agent modelling and simulation of HAI propagation dynamics through exogenous cross-infection by a contact transmission route in a hospital ward. The model relies on the Event Based Modelling and Simulation approach. It is meant to deal with a wide range of pathogen types and scenarios of their spread within a hospital environment, which can be extended to integrate relevant emerging factors in the dynamic evolution of HAIs. The Agent-Based application was validated through a virtual simulation of a case study built in a Unity 3D environment, which generates a real time infection risk map. The simulation represents the building and its users in the situation of HAI risk in a coherent and dynamic system. It allows for the visualization of contamination propagation due to human spatial behaviour and activities. The case study was tested through a what-if scenario, allowing for the real-time visualization of transmission and assessing the effectiveness of different prevention and control measures on pathogen propagation. Of further interest was an understanding of the influences of architectural design and space distribution
A Multi-Agent Simulator for Infection Spread in a Healthcare Environment
Get PDFA Multi-Agent simulator made in Unity 3D is proposed to track the spread of Hospital Acquired Infections transmitted by contact in hospital wards. The tool generates a real-time contamination risk map for both people and spaces, depending on the profile, behavior and activities of virtual agents, the characteristics of pathogens and the role of inanimate objects and places
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
