120595.pdf (Publisher’s version ) (Open Access)This dissertation concerns the evaluations of critics in literary book reviewing in Dutch newspapers between 1955 and 2005. Analyses of literary evaluation in its literary-historical context have so far tended to concentrate on specific case studies – the reception of a single book or author, the poetics of a single reviewer – or on sociological aspects of book reviewing. This study, which is part of a larger research project titledThe Best Intentions, Literary Criticism in the Netherlands 1945-2005, aims to explore and describe which developments and continuities might be gleaned from evaluative statements in book reviews themselves. Both the critics’ judgments on (and characterizations of) literary works in reviews are considered relevant, because they affect relations and positions in the literary field. By employing both quantitative and qualitative analyses of evaluative statements, this study endeavors to test prevailing – but hitherto uncharted – hypotheses concerning various continuities and transformations in the realm of newspaper reviews of literary novelsRadboud Universiteit Nijmegen, 15 januari 2014Promotores : Joosten, J.H.T., Schellens, P.J.311 p
"An Acquired Taste": The Internal and External Posture of Nicola Barker, Metamodernist Author
No full textThis thesis looks at how Nicola Barker's internal and external posture are construed on the basis of her last three books, The Cauliflower® (2016), H(A)PPY (2017), and I Am Sovereign (2019), how different institutions react to these books and whether that posture can be considered metamodernist. The theoretical framework and methodology builds on Meizoz's notion of posture, the singular way of occupying a position within the literary field, as defined by Bourdieu. As for metamodernism, multiple important sources are examined, starting with Vermeulen and Van den Akker. The research concludes that Nicola Barker can indeed be considered a metamodernist author and her posture seems to construed as that of a working-class author with a nonconformist and anti-establishment attitude, as well as an unconventional and transgressively intermedial approach that, despite her abundantly employed irony, always seems to contain a moral core
Parallel Approach to Derivative-Free Optimization: Implementing the DONE Algorithm on a GPU
No full textResearchers at Delft University of Technology have recently developed an algorithm for optimizing noisy, expensive and possibly nonconvex objective functions for which no derivatives are available. The data-based online nonlinear extremum-seeker (DONE) was originally developed for sensorless wavefront aberration correction in optical coherence tomography (OCT) and optical beam forming network (OBFN) tuning. In order to make the DONE algorithm suitable for large-scale problems, a parallel implementation using a graphics processing unit (GPU) is considered. This master thesis aims to develop such a parallel implementation which performs faster than the existing sequential implementation without much change in obtained accuracy. Since OBFN tuning is a problem that may involve a large amount of parameters, an OBFN simulation is to be used to compare the parallel implementation to the sequential implementation. The key of the DONE algorithm is solving a regularized linear least-squares problem in order to construct a smooth and low-cost surrogate function which does provide derivatives and can be optimized fairly easily. This master thesis first discusses the basics of parallel computing, after which several linear least-squares methods and several numerical optimization methods are investigated. These methods are compared and the most suitable methods for parallel computing are implemented and tested for increasing dimensions. The final parallel DONE implementation combines the recursive least-squares (RLS) method with the Broyden-Fletcher-Goldfarb-Shanno (BFGS) method and optimizes the largescale OBFN simulation almost twice as fast as the sequential DONE implementation, without much change in obtained accuracy.Mechanical, Maritime and Materials EngineeringDelft Center for Systems and Control (DCSC
How Should Central Banks Respond to Inflating Real Estate Bubbles: A Qualitative Assessment of Industry Professionals’ Perceptions
No full textCentral Banks do not respond to inflating real estate bubbles, but abide a policy that ‘mops up’ the damage after their collapse with the conventional tools of monetary policy. The financial crisis of 2008 disclosed the flaws of this method, which triggered a controversial debate among policymakers and economists. Currently there is an elevated risk for credit-fuelled bubbles in prime residential- and commercial real estate markets. A literature review identified four theoretical perspectives that propose a range of widely varying policy modifications, implying there is no consensus. This research targeted this knowledge gap by assessing the perceptions of knowledgeable real estate professionals to test and criticize the theories via semi-structured interviews. The findings of this study appointed a countercyclical restriction of Loan-To-Value ratios for residential – and commercial real estate financing as an appropriate step to pioneer a policy modification that aims to counteract inflating real estate bubblesTechnology, Policy and ManagementEconomics of InnovationManagement of Technolog
The Two-Dimensional Development and Analysis of Blade Profiles Having Larger Turning Angles
Full text linkTitle: The Two-Dimensional Development and Analysis of Blade Profiles Having Larger Turning Angles, Author: Ramesh K. Malhotra, Location: ThodeThe advances in gas turbine technoloqy in recent years
has focussed attention on problems associated with the attainment of
high work output. This led to the consideration of high work output
per blade, and thereby to the consideration of designing the blades
with large turning angles. The blade's profile, pressure distribution, pressure gradients and
velocity triangles are drawn for each set of blades. The theoretical performance
of the blades has been examined over a range of incidence angles
from zero to nine degrees.ThesisMaster of Engineering (ME

Velocity Profiles in Annular Passages
Full text linkTitle: Velocity Profiles of Annular Passages, Author: Thomas W. Ricker, Location: ThodeAn experimental study of turbulent velocity profiles of water flowing in a vertical annular passage is reported in this thesis. Presented are profiles for eccentricities ranging from 0% to 80% and Reynolds numbers from 40,000 to 104,000 in an annulus having a 0.286 radius ratio. Velocities were measured along five radii for all but the concentric configuration and the two arbitrarily chosen configurations are represented in the form of cross-sectional maps of the isovels. A method for deriving the powers N1 and N2 as defined by the equations u/um = [(r2-r)/(r2-rm)]^N2 and u/um = [(r-r1)/(rm-r1)]^N1 is suggested, and these powers were found for the two configurations investigated.ThesisMaster of Engineering (ME

Wilson, Location: ThodeA theoretical analysis of the velocity and wall shear stress distributions for fully developed turbulent flow in annular passages is reported in this thesis. The study was carried out for a range of eccentricities from 0 to 80 percent and for Reynolds numbers from 20,000 to
100,000 for a radius ratio of 1/3.5 with an inner radius of 0.25 inches. For the concentric case, the solution was found to be in agreement with experimental fact.ThesisMaster of Engineering (ME
Turbulent Drag Reduction in Tubes with Polymer Solutions
Full text linkTitle: Turbulent Drag Reduction in Tubes with Polymer Solutions, Author: S. K. Verma, Location: ThodeThis thesis is a study of drag reduction with polymer solutions in tubes using a simple rheometer. The drag reduction was studied in five different small diameter tubes at Reynold's number varying from 1000 to 25000. A polyacrylamide, MRL-402, manufactured by Stein Hall Ltd. was chosen for the above study because of its good drag reducing ability and resistance to degradation. The concentrations of polymer solutions used for the experiment ranged from 1 to 200 wppm. An attempt has been made to correlate the drag reduction data so that drag can be predicted from a single curve. The correlations are given by equations β = β(s'T) and β = β' (s'/s'0.50 ) following the work of
