Prediction of Strap Joint Design Margin in After Treatment System
Get PDFThe automotive vehicle has an exhaust system, also known as the after treatment System. It consists of different components such as Diesel Oxidation catalysts (DOC), Diesel Particulate Filters (DPF), Selective Catalytic Reduction Systems (SCR), etc. These components are mounted in the chassis with the help of strap joints. The strap joints provide flexible and serviceable connections between ATS bodies and chassis. The strap joint assembly consists of a T bolt, trunnion, and nut with strap. As the nut tightened, the tension induced in the strap, which results in clamping the body. If the tension in the strap is not sufficient, it may cause the failure of the joint. The failure can be yielding of material, slipping, and separation of the body. The strap joint should be designed so that these kinds of failures can be avoided. This paper presents the work on the calculation of the design margin using analytical and FEA methods. The failure modes addressed in this paper are yielding of the strap joint due to applied preload on the T bolt, slipping, and separation of the ATS body from the strap due to the application of dynamic loads such as acceleration G loads in multiple directions. The acceleration load is calculated from the PSD profile. For calculating design margins from the FEA method, nonlinear analysis is performed, followed by PSD analysis to estimate the bracket reaction forces. These reaction forces are used to calculate slip and separation margins. The tests were performed under similar conditions on a shaker table, and the results from both analytical and FEA methods were correlated with test observations to validate the proposed method of calculation of strap join design margin.Published By: Blue Eyes Intelligence Engineering and Sciences Publication (BEIESP)

Nash Equilibria of Two-Player Matrix Games Repeated Until Collision
Get PDFWe introduce and initiate the study of a natural class of repeated two-player matrix games, called Repeated-Until-Collision (RUC) games. In each round, both players simultaneously pick an action from a common action set {1, 2, … , n}. Depending on their chosen actions, they derive payoffs given by n × n matrices A and B, respectively. If their actions collide (i.e., they pick the same action), the game ends, otherwise, it proceeds to the next round. Both players want to maximize their total payoff until the game ends. RUC games can be interpreted as pursuit-evasion games or repeated hide-and-seek games. They also generalize hand cricket, a popular game among children in India.
We show that under mild assumptions on the payoff matrices, every RUC game admits a Nash equilibrium (NE). Moreover, we show the existence of a stationary NE, where each player chooses their action according to a probability distribution over the action set that does not change across rounds. Remarkably, we show that all NE are effectively the same as the stationary NE, thus showing that RUC games admit an almost unique NE. Lastly, we also show how to compute (approximate) NE for RUC games

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
How BR Ambedkar’s radical critique of caste could transform transgender activism in India
No full textIn this piece, Swarupa and Aniket highlight that Ambedkar’s critique of caste was a critique of structural systemic injustice conceded as tradition. His insights, though rooted in caste, can be extended to the oppression of transgender individuals. A truly Ambedkarite approach to trans liberation must go beyond the politics of identity to a politics of transformation
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
