Poisson\u27s Equation

This presentation deals with how to solve Poisson\u27s Equation for a two dimensional plate. The numbers can be represented as heat, charge density, and gravitational force. This is a generalization of Laplace\u27s Equation, which are steady state problems. In this problem, it is broken up into two simpler problems. For the first part, there are two ways of solving it since it is two dimensional. This presentation covers both ways of solving it using separation of variables, orthogonality, and partial differential equations. In addition, it shows how to solve the second part and finalize Poisson\u27s Equation

Data Insertion in Bitcoin\u27s Blockchain

This paper provides the first comprehensive survey of methods for inserting arbitrary data into Bitcoin\u27s blockchain. Historical methods of data insertion are described, along with lesser-known techniques that are optimized for efficiency. Insertion methods are compared on the basis of efficiency, cost, convenience of data reconstruction, permanence, and potentially negative impact on the Bitcoin ecosystem

Low back pain status in elite and semi-elite Australian football codes: a cross-sectional survey of football (soccer), Australian rules, rugby league, rugby union and non-athletic controls

<p>Abstract</p> <p>Background</p> <p>Our understanding of the effects of football code participation on low back pain (LBP) is limited. It is unclear whether LBP is more prevalent in athletic populations or differs between levels of competition. Thus it was the aim of this study to document and compare the prevalence, intensity, quality and frequency of LBP between elite and semi-elite male Australian football code participants and a non-athletic group.</p> <p>Methods</p> <p>A cross-sectional survey of elite and semi-elite male Australian football code participants and a non-athletic group was performed. Participants completed a self-reported questionnaire incorporating the Quadruple Visual Analogue Scale (QVAS) and McGill Pain Questionnaire (short form) (MPQ-SF), along with additional questions adapted from an Australian epidemiological study. Respondents were 271 elite players (mean age 23.3, range 17–39), 360 semi-elite players (mean age 23.8, range 16–46) and 148 non-athletic controls (mean age 23.9, range 18–39).</p> <p>Results</p> <p>Groups were matched for age (p = 0.42) and experienced the same age of first onset LBP (p = 0.40). A significant linear increase in LBP from the non-athletic group, to the semi-elite and elite groups for the QVAS and the MPQ-SF was evident (p < 0.001). Elite subjects were more likely to experience more frequent (daily or weekly OR 1.77, 95% CI 1.29–2.42) and severe LBP (discomforting and greater OR 1.75, 95% CI 1.29–2.38).</p> <p>Conclusion</p> <p>Foolers in Australia have significantly more severe and frequent LBP than a non-athletic group and this escalates with level of competition.</p

A Discontinuous Galerkin Method for the CEV Process

This thesis exams the valuation of American and European Put options whose underlying assets follow a generalized Black-Scholes (CEV) process. This thesis establishes a Discontinuous Galerkin Numerical Method for approximating the resulting PDEs in valuing options. This thesis examines the method's convergence, and compare the method to other known numerical methods for valuing options, such as the Binomial Method. An extension of the method to higher dimensions for valuing basket options is also discussed

Evaluating the relevance and clarity of the heart failure eMeasure implementation toolkit by using a webbased survey instrument

Background: The impact on workfl ow is an important component in determining whether an HIT implementation will be successful. Workfl ow is, unfortunately, a concept that is often ignored when implementing HIT and the literature about workfl ow in domains of quality improvement, system implementation, and process improvement has not been adequate. HIT is not always designed to fi t the workfl ow of a given organization, making it diffi cult to truly assess HIT impact on outcomes or processes.</p
