Defect correction methods for computational aeroacoustics
The idea of Defect Correction Method (DCM) has been around for a long time. It can be used in a number of different ways and can be applied to solve various linear and non-linear problems. Most defect correction related methods were used in conjunction with discretisation methods and two-level …

Slip-Correction Methods for Improved Dead Reckoning in Autonomous Wheeled Robots
This work compares methods for improving the dead-reckoning capabilities of a mobile robot in the presence of longitudinal slip. They were evaluated using a standardized test of driving in a 140-centimetre square. Testing was conducted on high-friction rubber and low-friction artificial ice …

Comprehensive evaluation of error correction methods for high-throughput sequencing data
… Different technologies use different underlying methods for sequencing and are prone to different error rates. Though many tools exist for error correction in high-throughput sequencing data, no standard technology-independent method is available yet to evaluate the accuracy and effectiveness of …

Development of a new shock capturing formula for pressure correction methods
Several methods have been developed to capture shock waves in turbo machinery flows, such as Moore's pressure correction procedure and Denton's time marching procedure. The time marching procedure is traditionally used for transonic flow calculations, whereas the pressure correction method is …

A Scheme for Ultra-Fast Computed Tomography Based on Stationary Multi-Beam X-ray Sources
… interior CT mode, X-ray scattering, and scatter correction methods. First, a single CNT X-ray source based interior micro-CT was constructed to serve as a down-scaled experimental verification platform for interior CT mode. Interior CT mode demonstrated comparable contrast-noise-ratio (CNR) and …

Correction of target-controlled infusion following the wrong selection of emulsion concentration of propofol
Background: We investigated the correction methods following wrong-settings of emulsion concentrations of propofol as a countermeasure against erroneous target-controlled infusions (TCI). Methods: TCIs were started with targeting 4.0 μg/ml of effect-site concentration (Ceff) of propofol, and the …

Power factor correction and power consumption characterization of piezoelectric actuators
… question: What effect does applying power factor correction methods to piezoceramic actuators have on their power consumption characteristics? A subproblem we explored was to detennine the qualitative relationship between the power consumption of a piezoceramic actuator and the damping that …

Implementation of anatomical navigators for real time motion correction in diffusion tensor imaging
Prospective motion correction methods using an optical system, diffusion-weighted prospective acquisition correction, or a free induction decay navigator have recently been applied to correct for motion in diffusion tensor imaging. These methods have some limitations and drawbacks. This article …
