Addressing The Inverse Problem of Imaging With ‘Heavy Atom’ Optics
Frontiers in Optics 2012/Laser Science XXVIII, 2012A solution for inverse problems in imaging is experimentally demonstrated using a nanoscopically controllable delta function reference source to solve the phase problem of far-field imaging exactly with super-resolution potential.

Addressing non‐uniqueness in linearized multichannel surface wave inversion
Geophysical Prospecting, 2008ABSTRACTThe multichannel analysis of the surface waves method is based on the inversion of observed Rayleigh‐wave phase‐velocity dispersion curves to estimate the shear‐wave velocity profile of the site under investigation. This inverse problem is nonlinear and it is often solved using ‘local’ or linearized inversion strategies.

Addressing an inverse problem of classifier size distributions
Powder Technology, 2007One input and two output stream classifiers are commercially employed for the classification of particles. A mass balance equation for a classifier suggests that the feed size distribution can be evaluated from measured product size distributions if and only if the flow split of the feed particles to one of the product streams is also known.

The Journal of the Acoustical Society of America, 2006
The intrinsically non-Gaussian statistics of nonlinear inverse problems, including ocean geoacoustic problems, is explored via analytic rather than numerical means. While Monte Carlo Bayesian methods do address the non-Gaussian statistics in nonlinear inverse problems, they can be very slow, and intuitive interpretation of the results are at times ...

Addressing artifacts in PP-PS registration prior to performing joint impedance inversion
The Leading Edge, 2020Multicomponent seismic data analysis enhances confidence in interpretation by providing mode-converted PS data for imaging the subsurface. Integrated interpretation of PP and PS data begins with the identification of reflections corresponding to similar geologic events on both data sets.

Interactive Multi-Objective Inverse Groundwater Modeling — Formulation and Addressing User Fatigue
World Environmental and Water Resource Congress 2006, 2006This paper builds on work done on using interactive multi-objective genetic algorithms (IMOGA) to solve the groundwater inverse problem (Singh & Minsker, 2005) by searching for optimal hydraulic conductivity fields conditioned on field measurements of hydraulic heads and conductivities. The biggest challenge faced when using such interactive systems is

4D FWI: Strategies for addressing the inversion noise
The Leading Edge4D full-waveform inversion (FWI) is increasingly being used for time-lapse data processing. It provides two main advantages. First, the enhancement in image quality that FWI offers compared to traditional imaging methods is significant, particularly in regions with complex overburden and poor illumination.

Selective charge-inversion addressing method for driving AC plasma display panel
Displays, 2002This paper proposes a method to drive an AC plasma display panel at a significantly reduced scan time. To reduce the scan time, the proposed method uses an unselective dark reset discharge, which turns on all cells weakly, and then writes the picture data using a selective charge-inverting scan discharge.

Honored guest's address. The inverse relationship between cost and prognosis
The Laryngoscope, 1984AbstractWhile doctors get the blame for increasing medical costs, studies show that societal, political factors, and medicine's limitations are the culprit.Clinicians (I use the term to distinguish between those M.D.s who work at the bedside and others who are in nonpatient direct care) are well aware of the huge costs associated with serious illness ...

Current Developmental Disorders Reports, 2018
The aim of the study is to examine the current evidence of systems and structures for accessing neurodevelopmental disorder services, with a focus on developmental coordination disorder (DCD). Despite evidence that DCD co-occurs with a number of other developmental disorders, services are often delivered for single conditions separated in space and ...
