The inversion accuracy in optoacoustic tomography depends on a number of parameters,
including the number of detectors employed, discrete sampling issues or imperfectness of …

The application of sound field control to outdoor live events at low frequencies is a recent
one due to increased concerns regarding noise pollution and stronger regulations. Here is …

We developed a seismic-attenuation-tomography algorithm for improving image amplitude
fidelity and other geophysical applications. This algorithm is based upon the centroid …

The solution of linear inverse problems when the unknown parameters outnumber data
requires addressing the problem of a nontrivial null space. After restating the problem within …

Tikhonov regularization is one of the most popular methods for the solution of linear discrete
ill-posed problems. In many applications the desired solution is known to lie in the …

For the solution of large sparse nonnegative constrained linear least squares (NNLS)
problems, a new iterative method is proposed which uses the CGLS method for the inner …

An interior point approach for medium and large non‐negative linear least‐squares
problems is proposed. Global and locally quadratic convergence is shown even if a …

Linear least squares problems with box constraints are commonly solved to find model
parameters within bounds based on physical considerations. Common algorithms include …

Image deconvolution problems with a symmetric point-spread function arise in many areas
of science and engineering. These problems often are solved by the Richardson-Lucy …

Sound field control can be applied to the problem of reducing noise emissions from outdoor
live music events. One method employed in this type of applications is pressure matching …
