Inverse Modeling to Quantify Microphysical Parameterization Uncertainty
This dissertation document details work completed in the field of cloud microphysical model error and uncertainty quantification. The general motivation is a need to account for error and uncertainty in microphysical parameterization schemes, which remain a large source numerical weather prediction error. The techniques used have been drawn from the fields of nonlinear parameter estimation, data assimilation and uncertainty quantification. First, microphysical parameter uncertainty has been quantified in a manner identical to that of Posselt and Vukicevic (2010), except that a vertically resolved simulated radar reflectivity observation was used as observation constraint on parameter uncertainty, rather than column-integral observations (such as IWP, LWP, etc.). This necessitated work on estimation of the error characteristic of the vertically resolved radar reflectivity observations, in particular, the estimation of a vertically correlated radar error model. Additionally, work has been conducted on estimating uncertainty in microphysics schemes by using perturbations on the hydrometeor time tendency equations as control parameters within a probabilistic Monte Carlo inversion. In order to further facilitate probabilistic inverse modeling studies, and to provide an educational tool for future students, a simplified, Matlab-based framework has been developed for testing advanced Monte Carlo techniques on simple models (e.g. damped harmonic oscillator, Lorenz 1963 model, etc). Finally, an ensemble Kalman transform smoother (EnTKS or ETKS, Posselt and Bishop (2012)) is used to confim that new choices of uncertain model control variables may aid in the use of ensemble Kalman techniques for non-Gaussain model uncertainty analysis.</p

A Tripartite Post-Recession Rebalancing
In this latest Advance & Rutgers Report, entitled “A Tripartite Post-Recession Rebalancing,” Dean James W. Hughes and Professor Joseph J. Seneca deliver an incisive assessment of the current market conditions and obstacles in the path of our economic recovery. They offer a statistical cautionary tale that the private and public sector need to hear and acknowledge in order for the economy to make continued progress.This report was published as Issue Paper Number 7, November 2011, in Advance & Rutgers Report
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
First evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
Abstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
