There is a need for new numerical tools to capture the physics of floating offshore wind turbines (FOWTs) more accurately refine engineering designs and reduce costs. The conventional measurement apparatuses in tank tests, including wave probes, velocity current profilers, Doppler sensors, are unable provide full 3D picture velocity, pressure, turbulence, vorticity profile. In use underwater st...

A method is proposed that allows threedimensional (3D) two-component measurements to be made by means of particle image velocimetry (PIV) in any volume illuminated over a finite thickness. The method is based on decomposing the cross-correlation function into various contributions at different depths. Because the technique is based on 3D decomposition of the correlation function and not reconst...

The paper argues that the conventional methodology of software engineering is inappropri­ ate to AI, but that the failure of many in AI to see this is producing a Kuhnian paradigm "crisis". The key point is that classic software engineering methodology (which we call SPIV: Specify­ Prove-Implement-Verify) requires that the problem be circumscribable or surveyable in a way that it is not for are...

This work presents reconstructions of 3D pressure fields starting from 2D3C stereoscopic-PIV (SPIV) measurements. In Fratantonio et al. (2021), we presented a new reconstruction algorithm, the “Instantaneous convection” method, capable producing velocity time-resolved SPIV For in flows with strong shear layers and high turbulence intensity, this method is able to provide volumes that are more a...

This paper describes a probabilistic framework for studying associations between multiple genotypes, biomarkers, and phenotypic traits in the presence of noise and unobserved confounders for large genetic studies. The framework builds on sparse linear methods developed for regression and modified here for inferring causal structures of richer networks with latent variables. The method is motiva...

The purpose of our research is to validate an experimental method developed by Johnson and Cowen (2016) aimed at measuring volumetric discharge in open channel using Surface particle image velocimetry (SPIV) combined with turbulent boundary layer analysis infer the bathymetry calculate flow rate, ultimately extending this work natural systems (Hendrickson, 2020).

In this paper, the performance of Reynolds Averaged Navier Stokes (RANS) simulations was evaluated to predict the flow structure developed by the presence of a sidewall obstruction in a uniform open-channel shallow flow. The study of these flow structures is important because they present in several real world configurations, such as groynes in rivers, where the erosion processes, mass transpor...

The following research paper presents an up to date status of the design and testing of a Dual-Mode Scramjet model which is experimentally operated at UVa’s Aerospace Research Laboratory. The demand for application of advanced optical measurement techniques has facilitated the complete re-design of all test sections. The details of the design, analysis, and capabilities of the DMSJ are the focu...
