Direct ultrasonic holography: Feasibility demo [PDF]

Acoustics Research Letters Online, 2005
Holography is potentially the most powerful method for high spatial resolution real time 3D ultrasound imaging and diagnostics. Although versions of ultrasound holography have existed since the 1970s, they use laser reconstruction, thus losing 3-D resolution.

The NFDA-Nonsmooth Feasible Directions Algorithm applied to construction of Pareto Fronts of Ridge and Lasso Regressions

Trends in Computational and Applied Mathematics
Ridge and Lasso regressions are types of linear regression, a machine learning tool for dealing with data. Based on multiobjective optimization theory, we transform Ridge and Lasso regression into bi-objective optimization problems. The Pareto fronts of
