On Hagelbarger’s and Shannon’s matching pennies playing machines

2020

Abstract In the 1950s, Hagelbarger’s Sequence Extrapolating Robot (SEER) and Shannon’s Mind-Reading Machine (MRM) were the state-of-the-art research results in playing the well-known “matching pennies” game. In our research we perform a software implementation for both machines in order to test the common statement that MRM, even simpler, beats SEER. Also, we propose a simple contextual predictor (SCP) and use it to compete with SEER and MRM. As expected, experimental results proves the claimed MRM superiority over SEER and even the SCP’s superiority over both SEER and MRM. At the end, we draw some conclusions and propose further research ideas, like the use of mixing models methods and the…

A Bayesian analysis of the thermal challenge problem

2008

Abstract A major question for the application of computer models is Does the computer model adequately represent reality? Viewing the computer models as a potentially biased representation of reality, Bayarri et al. [M. Bayarri, J. Berger, R. Paulo, J. Sacks, J. Cafeo, J. Cavendish, C. Lin, J. Tu, A framework for validation of computer models, Technometrics 49 (2) (2007) 138–154] develop the simulator assessment and validation engine ( SAVE ) method as a general framework for answering this question. In this paper, we apply the SAVE method to the challenge problem which involves a thermal computer model designed for certain devices. We develop a statement of confidence that the devices mode…

Elementary Deformations and the HyperKähler-Quaternionic Kähler Correspondence

2014

The hyperKahler-quaternionic Kahler correspondence constructs quaternionic Kahler metrics from hyperKahler metrics with a rotating circle symmetry. We discuss how this may be interpreted as a combination of the twist construction with the concept of elementary deformation, surveying results of our forthcoming paper. We outline how this leads to a uniqueness statement for the above correspondence and indicate how basic examples of c-map constructions may be realised in this context.

Desarrollo de habilidades de modelación desde las ecuaciones más simples de la Hidrodinámica

2017

[EN] The development of modeling skills is a very important issue in Science teaching nowadays. The present workillustrates how, from the simplest equations of hydrodynamics, it is possible to contribute to this end. Bernoulliand continuity equations are included in Physics syllabi of secondary and university levels, and can be seen as alinking between general and professional education. By means of the proposed project, students are taken throughgeneral stages which are usually present in any engineering project or research work based on modeling and simu-lation. such as the formulation of the problem, the statement of the Physics model, a computational simulationand the comparison between…

Who shapes the news? Analyzing journalists’ and organizational interests as competing influences on biased coverage

2018

This study investigates influences on gatekeeping processes that have the potential to cause biased media coverage. We tested whether and, if so, to what extent journalists’ and organizational interests affect journalistic news processing. In a content analysis, we contrasted the press coverage (n = 1199 articles) of trade disputes of newspaper journalists with the coverage of other trade disputes. Results indicate both coverage and statement bias. In their coverage of newspaper disputes, journalists evaluated employers’ offers significantly more negatively, framed industrial action as legitimate, and criticized employers’ behavior during strikes.

OS ECJ-TF 1/2018 on the Compatibility of Limitation-on-Benefits Clauses with the EU Fundamental Freedoms

2018

This article deals with compatibility of limitation-on-benefits (LoB) clauses with the EU fundamental freedoms, based on decisions of the European Court of Justice (ECJ). The context of this statement is the Commission's infringement procedure against the Netherlands with regard to the LoB clause in the Japan-Netherlands Income Tax Treaty (2010) and the inclusion of a simplified optional LoB clause in the BEPS Multilateral Instrument.

Some Preliminary Remarks on the World Council of Churches’ Central Committee Statement on Religion and Violence

64 The fact that ‘the scandal of poor medical research’ by douglas altman (1994) largely holds true today insinuates the persistent conduct and disse…

2019

The objective of this submission is to describe four additional suggestions to alleviate issues around the quality of research and publications. Currently, positive results are twice as likely to be published as negative results. Advocating the publication of negative findings too would beseech individuals to report true findings and be less tempted to fabricate data. Moreover, negative findings help expedite the process of uncovering positive results and is supported by ‘Missing pieces’ by PLOS ONE and the journal ‘Negative results’. However, their negligible impact factor and low profile may dissuade researchers from exhibiting their work here. It can be challenging for new journals to co…

On Association Models Defined over Independence Graphs

1998

Conditions on joint distributions are given under which two variables will be conditionally associated whenever an independence graph does not imply a corresponding conditional independence statement. To this end the notions of parametric cancellation, of stable paths and of quasi-linear models are discussed in some detail.
