The "Fair" Triathlon: Equating Standard Deviations Using Non-Linear Bayesian Models
… triathletes that the swimming portion of the standard-distance triathlons is underweighted. We present a nonlinear Bayesian model for triathlon finishing times that models time and standard deviation of time as a function of distance. We use this model to create "fair" triathlons by equating …

A Comparison of Implied Standard Deviations and Historical Estimates of Volatility During and After the Participation of the British Pound in the ERM
This thesis tests the hypothesis that the qualities of different forecasts of exchange rate volatility depend on the underlying exchange rate regime. By examining the British pound during and after its withdrawal from the European Monetary System (EMS), this analysis compares "backward-looking" …

Station Delays, Their Standard Deviations, and Event Relocations in the Reno-Area Basin from a Dense USArray Flexible Array Deployment during the 2008 West Reno Earthquake Swarm
… a mode-of-station-delay map, and a map of the standard deviations of the average station delays confirm that the western part of the basin is thickest. Negative delays and high standard deviations in delay times in the Verdi Basin confirmed the basin to be narrow and complex.

Degrees of motor program control
… experiments. The findings indicated that the standard deviations of movement times increases as movement duration increased. However, at longer movement durations, the presence of a visual feedback display decreased the standard deviations of movement times. In Experiment III, the rate of …

Effects of within herd variation on the relationship between genetic evaluations and performance of offspring
… to compute herd-year means and within herd-year standard deviations for individual mature equivalent (ME) milk, fat, and fat percent. These herd-year means and within standard deviations were used to stratify records into five classes. Regressions for individual daughter's modified contemporary …

Testing Numeric: Evidence from a randomized controlled trial of a computer based mathematics intervention in Cape Town high schools
… to teach basic numeracy. Large gains of 0.321 standard deviations were observed on basic numeracy outcomes for learners who were selected to be on the programme. Similarly, learners in treatment also scored 0.246 standard deviations higher on core Grade 8 curriculum questions at endline. The …

Evidence for a narrow Higgs-like diphoton resonance with a mass of 125 GeV in pp collisions at [square root of]s = 7 - 8 TeV
… performed a search for the production of the standard model Higgs boson decaying to diphotons in pp collisions at the LHC at [square root of]s = 7-8 TeV with the CMS detector. Having analyzed data corresponding to 5.1 fb-1 at [square root of]s = 7 TeV (2011) and 5.3 fb-1 at [square root of]s = …

Digital Microradiography: In Vitro Validation of a Novel Imaging Technique
… are considerable limitations of this ageing gold standard such as unavailability of the high-resolution spectroscopic plates and prolonged imaging and processing times. The present study aimed at developing and validating a novel digital microradiographic technique that is not restricted by the …

Fibromyalgia and Rheumatoid Arthritis: The Relationship Between Pain, Depression, and Family Health
… depression, such that as pain increased by one standard deviation depression increased by .48 standard deviations (β = .48, p < .05). Depression was also significantly associated with family health as depression increased by one standard deviation, family health decreased by .23 standard …

An investigation into reference-day risk-free metrics in the context of modern portfolio theory on the JSE
… For example, the accuracy of expected returns, standard deviations and correlations as an input into MPT will result in a more efficient selection of the optimal portfolio. These metrics are exposed to reference-day risk which is the variation in input estimation due to the selection of initial …

The Information Content of Dividends: An Empirical Analysis of Warrants Conducted by Examination of the Implied Variability of Stock Prices
… between security returns (and their implied standard deviations) and the dividend announcement. The relationship of firm size (as determined by market value) to stock variability is concurrently examined. This experiment, staged in event-time, employs an ex-ante methodology which is couched …

Horizontal plane head and trunk motion during locomotion
… trunk and head movements during all tasks. Standard deviations of position were examined to determine relative stability of head and trunk segments with respect to normal. Multivariate analysis of variance showed standard deviations of head and trunk were similar within each task ($p > …

Searching for the Higgs Boson Produced in Association with a Pair of Top Quarks in Multilepton Final States Using the ATLAS Detector at the LHC
… an observed (expected) significance of 1.3 (0.9) standard deviations relative to the Standard Model background-only hypothesis. The combined ttH multilepton analysis also found an excess of events above the background-only expectation corresponding to an observed (expected) significance of 4.1 …

Evidence for a Higgs boson in tau decays with the CMS detector
… fb-1 at 8 TeV. The expected significance for a Standard Model Higgs boson signal with a mass of 125 GeV is at the level of 1.2 standard deviations for the electron muon tau-pair decay mode. A mild excess of events is seen above the SM background expectation in this decay mode, consistent with a …

Observation of electroweak W±W± JJ production with the CMS experiment
The CMS detector at the CERN LHC is sensitive to Standard Model predictions regarding the production of two W bosons with the same charge accompanied by two jets. In particular, when these particles are produced in a topology where the jets have a high invariant mass and are largely separated in …

A line photogrammetry algorithm for 3D rectilinear object reconstruction
… both test cases, X² tests were applied, and the standard deviations calculated. In the aerial case, standard deviations obtained were generally in the region of about 5cm. The ground resolution of the images was 7.Scm. In the close-range case the ground resolution was approximately 1.3mm, and the …
