PROPELLER DUO: Applied to Diffusion-Weighted Imaging
Introduction: Fast Spin Echo (FSE) could suffer from the non-CPMG condition that results in destructive echo interference, unstable echo train and signal cancellation. Diffusion-weighted (DW) PROPELLER [1], an FSE-based sequence, mitigates the non-CPMG issue by XY phase cycling [1] combined with split-blade acquisition [2]. However, XY phase cycling requires refocus flip angle be close to 180° ...
متن کاملApplication of Honey to Reduce Oxidation in Soybean Oil
Background: The oxidation of unsaturated lipids by free radicals is one of the main causes of food deterioration. The major purpose of the present study was to determine effectiveness of application of honey in order to reduce oxidation in soybean oil. Methods: Six groups were designed, including control (soybean oil emulsion without preservative), positive control (butylated hydroxyl toluene ...
متن کاملModulation-Based Digital Noise Reduction for Application to Hearing Protectors to Reduce Noise and Maintain Intelligibility
OBJECTIVE The objective of this study was to test the effects of modulation-based digital noise reduction (MB-DNR) on noise levels, speech intelligibility, and listening preference in four real-world noises. BACKGROUND A significant challenge in hearing protection device (HPD) design is to reduce ambient noise levels while maintaining users' ability to understand speech. MB-DNR technology, cu...
متن کاملCharacteristic Evaluation of a Shrouded Propeller Mechanism for a Magnetic Actuated Microrobot
Medical microrobots have been widely used in clinical applications, particularly the spiral type locomotion mechanism, which was recently considered one of the main self-propelling mechanisms for the next medical microrobot to perform tasks such as capsule endoscopy and drug delivery. However, limits in clinical applications still exist. The spiral action of the microrobot while being used for ...
متن کاملApplication of kriging to motorsport aerodynamic analysis
Aerodynamic analysis in motorsport is conducted using three methods, computational, scaled experimental and full-scale operational. However, the varying fidelity, different sampling resolutions and unavoidable errors of each technique make valid comparisons between datasets from each method difficult and time consuming. Kriging is a geostatistical method to estimate values within a data field b...
