Method for determining a characteristic quantity for correction of measured values of a Coriolis mass flowmater
No full textThe invention relates to a method for determining at least one characteristic variable for the correction of measured values ??of a Coriolis mass flowmeter. Furthermore, the invention relates to a Coriolis mass flowmeter having at least one measuring tube, at least two sensors and at least one actuator, wherein the measuring tube to the actuator to at least one oscillation can be excited.
A method for determining at least one parameter for the correction of measured values ??of a Coriolis mass flow meter, which is characterized by an increased accuracy and improved reliability in the determination of the characteristic is realized by the following method steps comprising:
- Detecting values ??of a measured variable at constant flow with the transducers,
- Calculating at least one location parameter from the detected values,
- Calculating at least one scattering parameter of the detected values ??and the location parameter,
- Detecting said additional values ??and calculating scattering parameters and position parameters of the existing and additional values ??is carried out frequently, and the dispersion parameter reaches a threshold value as a selection criterion, and
- Wherein the location parameter corresponding to the scattering parameter is used as a parameter for the correction of the measured values ??of the Coriolis mass flowmeter
Bayesian nonparametric estimation of a copula
Get PDFA copula can fully characterize the dependence of multiple variables. The purpose of this paper is to provide a Bayesian nonparametric approach to the estimation of a copula, and we do this by mixing over a class of parametric copulas. In particular, we show that any bivariate copula density can be arbitrarily accurately approximated by an infinite mixture of Gaussian copula density functions. The model can be estimated by Markov chain Monte Carlo methods and the model is demonstrated on both simulated and real data sets

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
