Characterization of the measurement uncertainty for the electromagnetic conducted and radiated emission test
… for testing. The USA with its FCC regulations uncertainty ULAB= 2uc(y). The thesis focused the application of the expanded uncertainty deployment for the judgement criteria for the finalize EUT status. The expanded uncertainty for both measurement CE and RE are 3.058 dB and 4.2 – 4.58 dB …

Communicating measurement uncertainty : an experimental study of financial reporting implications for managers and investors
… or by managers, would be intended to communicate measurement uncertainty to investors. Knowing this information should enhance investors’ ability to identify aggressive reporting, thereby possibly increasing investor actions taken against managers. In a laboratory experiment, I find that students …

Particle Image Velocimetry Correlation Signal-to-noise Metrics, Particle Image Pattern Mutual Information and Measurement uncertainty Quantification
In particle image velocimetry (PIV) the measurement signal is contained in the recorded intensity of the particle image pattern superimposed on a variety of noise sources. The inherent amount of signal mutual information between consecutive images governs the strength of the resulting PIV cross …

An uncertainty model of a non-ideal open area test site for electromagnetic measurement
… a product for compliance testing. However, measurements in the non-ideal OATS have higher uncertainty. In addition, the existing model to analyse the measurement uncertainty is not adequate. Therefore, this research proposes an uncertainty model of a non-ideal OATS for electromagnetic …

The Computation and Visualization of Uncertainty in Surgical Navigation
… calculation and visualization of intraoperative measurement uncertainty in computer-assisted surgical procedures. Error is the difference between the observed or measured value and the true value (called ground-truth) of a quantity. Uncertainty is the unknown difference between the measured and …

Well-Conditioned Heat Transfer Measurements on Engine Scale Gas Turbine Rigs
… balance correctly. An experimental heat transfer measurement technique is developed in this thesis, which builds on a large body of existing literature. The technique enables a detailed quantification of turbine heat transfer on test rigs which closely represent gas-turbine engine configurations. …

Impact evaluation of cyber-physical uncertainty on power systems
… the impact on power system performance of uncertainty arising from physical and cyber components of power systems. If the impact of the uncertainty arising from emerging technologies is not fully understood, it will likely lead to the deployment of unreliable and unsafe systems, which could …

Geostatistical modelling of recreational fishing data: A fine-scale spatial analysis
… decisions as such data are associated with uncertainty. In Western Australia, recreational fishing has a participation rate of approximately 30%. Data for this thesis were collected from boat-based recreational fishers through phone-diary surveys at spatial resolution that supports spatial …

Spin-squeezing of ⁸⁷Rb via optical measurement
This project aims to reduce measurement uncertainty in atomic clocks by squeezing the collective spin of atoms. Spin-squeezing reduces noise below the standard quantum limit where precision scales as 1/ [square root of] N, allowing us to instead approach the Heisenberg limit where it scales as 1/N. …

Quantum Resource Theories for Thermodynamics, Reference Frames, and Uncertainty
… enable us to also develop resource theories for measurement uncertainty and reference frames; in fact, the resource-theoretic treatment of thermodynamics is a combination of these two. Our approach is based on a model called thermal operations, applicable on individual quantum-mechanical systems …

Development and Validation of Reconstruction Algorithms for 3D Tomography Diagnostics
… of the problems when they are in 3D, and the measurement uncertainty. These algorithms are: an algebraic reconstruction technique (ART) screening algorithm, a nonlinear iterative reconstruction technique (NIRT), and an iterative reconstruction technique integrating view registration …

Towards Autonomous Localization of an Underwater Drone
… system exhibiting an additive error in location measurements. We evaluate the accuracy of this Kalman Filter by analyzing the effect each parameter has on accuracy, then choosing the best combination of parameter values to assess the overall accuracy of the Kalman Filter. We find that the two …

Improved approaches to the indirect force determination problems via experimental modal analysis
… identification error and control the response measurement uncertainty. The use of rotational or curvature degrees of freedom as an alternative to the translational degrees of freedom for the response measurements and for the structural dynamics model yields a quite differently conditioned …

Decision support tools for urban air quality management
… unavailable. The method directly incorporates measurement uncertainty, prior knowledge, and provides for a formal framework to combine measurements of different quality. Applying the method to data from Mexico City, evidence for stable and metastable aerosols was found. Gas phase concentrations …

Measuring single-cell density using serial suspended microchannel resonators
… The system design and operation are described, measurement uncertainty is characterized, and single-cell density measurements are compared to those obtained using existing techniques. As a demonstration, we use the system to characterize the biophysical response of CD8' T cells during …
