Design Considerations for Auditory Alarms in the Process Industry: A Systematic Literature Review
No full textThis study focuses on the research of design methodologies on the topic of auditory alarms in the context of the process industry. The overall goal of this research is to provide input for both process companies and auditory alarm designers for future development. Specifically, this study uses a systematic literature review on previous peer-reviewed papers on the design and characteristics of auditory alarms in the process industry. The background chapter will provide basic understanding of different factors to consider when designing auditory alarms.
Results identified in from the SLR are that there is little research done in this area. Eight papers was included, and these provided insight from on how the design methodology should be handled in accordance to industry standards, specified characteristics of auditory alarms and human factors considerations. By design, the standards have more of a focus on what to do rather than how to do it, where it can become a challenge for auditory alarm designers. The provided results from the systematic literature review and standards can be used as a simplified guidance on the design of auditory alarms intended for both the use in the process industry, but also for other control room applications.
Further research on this topic would be on the improvement effects of implementing new/redesigned auditory alarm systems, in relation to the standards set by the industry today. Further design and experimental testing of auditory alarms should be considered from human factors point of view, where both the standards and literature suggests this to be the most effective design for operators

Exploring the potential for augmented reality to assist dynamic positioning operators. What operations has potential and what information is needed
Full text linkTechnology has quickly become a vital part of the everyday of a mariner on board a vessel. A major part of using the full potential of a vessel was the introduction of the dynamic positioning system (DP), a computer-based system that allows the mariner to keep the vessel in its exact position with high precision. The system requires a certified dynamic positioning operator (DPO) to monitor and interact with screens holding valuable information. This decreases the time they spend monitoring the surroundings’, which could lead to reduced situational awareness. In the past decade the development of augmented reality/mixed realityglasses (AR/MR) has rapidly increased with industrial grade products entering the market, the glasses which allows the user to watch digital projected data as well as their surroundings could be a solution to reducing the time the DPO spends looking down at the screens. There is littleto no research on when and how augmented reality/mixed reality glasses should be used in a maritime opetion nonetheless DP operations. The purpose of this thesis is to add to the knowledge gap and hopefully contribute to further research by asking the following research questions, RQ1: What type of dynamic positioning operations could the operator benefit from augmented reality glasses? RQ2: What information is needed to be displayed in the augmented reality in order for the operator to safely perform their work?
To investigate where augmented reality/mixed reality glasses have potential to benefit in dynamic positioning operations a study was carried out interviewing a sample of eleven participants of which eight are active dynamic positioning operators and three are dynamic positioning instructors. The qualitative data collected in the semi-structured interviews suggests the following dynamic positioning operations with a potential use-case for augmented reality/mixed reality glasses: Complex operations where the vessel is operating nearby or close to a platform, installation, or windmill whether it be supply, construction, inspection, or maintenance. The common factor is that the user has a visual reference to orient themselves by.On the matter of how it should be used the results suggests that the data of highest importanceis data on position keeping such like, position reference systems, thruster movement and forceand relative vessel movement. The research has found fitting DP operations, uncovered what type of information is important for the DPO in today’s system and gathered some suggestions on other potential information. The goal is that this research can be of help for further research and development of an AR/MR system that will improve safety at se
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
