A Framework for Simulation Validation & Verification Method Selection
No full textThirty years of research on validation and verification (V\&V) has returned a plethora of methods, statistical techniques, and reported case studies. It is that abundance of methods that poses a major challenge. Because of overlap between methods and time and budget constraints, it is impossible to apply all the available methods in a single study, so a careful selection of methods has to be made. This paper builds on two assumptions: a) that both simulations and V\&V methods can be defined on the basis of different characteristics and b) that certain V\&V methods are more suitable than others for different kinds of simulations. The present study aims at identifying the specific characteristics that make a V\&V method more effective and more efficient than others, when confronting these with the simulations' different characteristics. The conclusion will advance a methodology for choosing the most appropriate method or methods for validating and/or verifying a simulation.Organisation & GovernancePolicy Analysi

DNS of a counter-flow channel configuration
No full textMean flow and turbulence statistics of a compressible turbulent counter-flow channel configuration. This dataset is based on direct numerical simulations conducted using OpenSBLI (https://opensbli.github.io/), a Python-based automatic source code generation and parallel computing framework for finite difference discretisation. #============================================================================================== # Please cite the following paper when publishing using this dataset: # Title: Direct numerical simulation of compressible turbulence in a counter-flow channel configuration # Authors: Arash Hamzehloo, David Lusher, Sylvain Laizet and Neil Sandham # Journal: Physical Review Fluids # DOI: https://doi.org/10.1103/PhysRevFluids.6.094603 # ============================================================================================== Please note: Tables 1 and 2 of the above paper provide more detailed information on the counter-flow channels of this dataset. Each folder name of this dataset includes the Mach number, Reynolds number, domain size and grid resolution of a particular case, respectively. In each file, the first column contains the grid-point coordinates in the wall-normal direction () with the channel centreline located at . The mean stresses are defined as . Angle brackets denote averages over the homogeneous spatial directions (streamwise and spanwise ) and time. The Favre average is related to the Reynolds average as . The mean Mach number is defined as where is the local speed of sound. The turbulent Mach number is defined as . # ============================================================================================== Details of the OpenSBLI framework, its numerical methodology and existing flow configurations can be found in the following papers: OpenSBLI: Automated code-generation for heterogeneous computing architectures applied to compressible fluid dynamics on structured grids.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
