Comfort, experience, physiology and car seat innovation: Theory, Design and Evaluation
No full textThe development process of car seats is very complex and many factors have to be considered in the development, such as anthropometry, physiology, safety, design and comfort. A factor making it more complex is the fact that future cars should be more sustainable, making the need for weight reduction more prominent. Improving comfort and at the same time reducing weight is a new challenge. Car seat research in the area of comfort is mainly focused on the decrease of discomfort. The most that can be achieved in this respect is that the person no longer notices the discomfort. Another possibility is to implement physiological knowledge in the seat research process, to increase the comfort and health in such a way that people will notice it. This is the chosen area of research in this PhD thesis. This knowledge can help car and seat manufacturers to address the issue of comfortable and healthy lightweight car seats and to stay ahead of the competition. Possibilities to improve comfort in this way studied in this thesis are a massage system an automatic seat surface adjustment resulting in an optimal pressure distribution, a head rest with special features for the neck, a new lumbar support and a special seat contour developement process.Department of Industrial DesignIndustrial Design Engineerin
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
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
Digitalization of posture-based Seat Design: Developing car interiors by involving user demands and activities
No full textThe conventional development of a new automobile starts with a first proportional model. In this model, the exterior geometry of a car can be distinguished into vehicle, power train portfolio, market requests, safety requirements, and design target. The interior design results from the proportional model with specific characteristics, such as spaciousness, control and display concept, and ergonomic requirements. The automobile emerged from the sole purpose of transportation with driver orientation into a vacation or commuter experience of all users by a broad spectrum of comfort- and infotainment features. This is sustained by emerging mobility concepts like autonomous car concepts. In order to consider this change in mobility concepts, consumer habits and mobility behavior of users, the interior design becomes more important, which creates the frame for this PhD project. An essential part of the interior is the seat. This PhD thesis focuses on designing car interiors from the inside to the outside by user involvement.Applied Ergonomics and Desig
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
