A Graphical User-Interface for Propulsion System Analysis

NASA LeRC uses a series of computer codes to calculate installed propulsion system performance and weight. The need to evaluate more advanced engine concepts with a greater degree of accuracy has resulted in an increase in complexity of this analysis system. Therefore, a graphical user interface was developed to allow the analyst to more quickly and easily apply these codes. The development of this interface and the rationale for the approach taken are described. The interface consists of a method of pictorially representing and editing the propulsion system configuration, forms for entering numerical data, on-line help and documentation, post processing of data, and a menu system to control execution

Causal assessment in finite extensive-form games

Two finite extensive-form games are empirically equivalent when the empirical distribution on action profiles generated by every behavior strategy in one can also be generated by an appropriately chosen behavior strategy in the other. This paper provides a characterization of empirical equivalence. The central idea is to relate a game's information structure to the conditional independencies in the empirical distributions it generates. We present a new analytical device, the influence opportunity diagram of a game, describe how such a diagram is constructed for a given extensive-form game, and demonstrate that it provides a complete summary of the information needed to test empirical equivalence between two games.Causality, structural uncertainty, extensive form games

Digital 3D reconstruction of historical textile fragment

This paper presents a new methodology for reproducing historic fragment in 3D with realistic behaviour, providing users with a feel for the fragment detailing. The fragment piece originates from the English National Trust archive held in the collection at Claydon House. The aim is to utilize a combination of both 2D pattern software and state-of-the-art 3D technology to recreate a compelling and a highly realistic representation of historic fragment. The process starts with investigation of the textile construction. Textile fragments will be incomplete and/or have a level of deterioration therefore various recording techniques are to be explored. A combination of both photography and 3D scanning technology will be utilized throughout the methodology to accurately record the digital data. The equipment setting will be analyzed in order to produce an accurate working method. This paper forming part of a larger study, will specifically focus on the methodology for recording data from one fragment piece

Philosophical Issues in Sport Science

The role and value of science within sport increases with ever greater professionalization and commercialization. Scientific and technological innovations are devised to increase performance, ensure greater accuracy of measurement and officiating, reduce risks of harm, enhance spectatorship, and raise revenues. However, such innovations inevitably come up against epistemological and metaphysical problems related to the nature of sport and physical competition. This Special Issue identifies and explores key and contemporary philosophical issues in relation to the science of sport and exercise. It is divided into three sections: 1. Scientific evidence, causation, and sport; 2. Science technology and sport officiating; and 3. Scientific influences on the construction of sport. It brings together scholars working on philosophical problems in sport to examine issues related to the values and assumptions behind sport and exercise science and key problems resulting from these and to provide recommendations for improving its practice

What is the Philosophy of Sport?

A cursory glance at the daily sports news highlights perennial philosophical and ethical issues in sport: drug taking, cheating, corruption, discrimination and violence, amongst many others. Indeed, the hot topics on the day of writing include: a criminal investigation into corruption within a high profile sport Governing body, concern over the effects of concussion in contact sport, a judicial challenge on whether a card game should be classified as a sport, officials banned for match fixing, further discussion about the introduction of goal-line technology, and ongoing lamentation by politicians on the low profile of women’s sport. We are confronted with philosophical and ethical issues in sport on a daily basis and they regularly form heated arguments between aficionados everywhere. Sport is a large part of modern life. The issues that sport raises are even larger. And nearly everyone has an opinion. Many of those interested in these types of issues and discussions have not been explicitly introduced to philosophic methods or to the philosophy of sport as a distinct academic subject. Yet when these debates occur in the pub, on the terraces or in the media, those involved are engaging in a philosophical discussion about the meaning and value of sport and the concepts related to it. This chapter aims to provide an overview to the uninitiated as to the development and history of the philosophy of sport, the types of questions raised, and the methods used to answer them. It will demonstrate that what many people do naturally when they discuss sporting issues is essentially philosophy; but it will also highlight where and how philosophy is done badly and how philosophical arguments and skills can be improved

Why teamwork is not a virtue - a response to Gaffney

This paper seeks to provide a response to Gaffney's analysis of teamwork by arguing that teamwork is morally neutral rather than a virtue in itself. This conclusion will be supported by examples which demonstrate how teamwork can develop and foster undesirable traits and practices such as resentment, contempt and the purely instrumental use of others in the achievement of desired ends
