JET ENGINE INLET DISTORTION SCREEN AND DESCRIPTOR EVALUATION
Acta Polytechnica, 2017 Total pressure distortion is one of the three basic flow distortions (total pressure, total temperature and swirl distortion) that might appear at the inlet of a gas turbine engine (GTE) during operation.

Computer simulation for prediction of thermal distortion of JIS ADC12 flat-shape die-casting
Nihon Kikai Gakkai ronbunshu, 2014 A computer simulation method to predict the thermal distortion value of a high-pressure die cast part was investigated. The evaluated product was a flat-shape JIS ADC12 part. The actual distortion value of the part was measured by an optical 3D digitizer

Evaluation of system-related magnetic resonance imaging geometric distortion in radiation therapy treatment planning: two approaches and effectiveness of three-dimensional distortion correction [PDF]
, 2022 We propose two methods to evaluate system-related distortion in magnetic resonance imaging (MRI) in radiation therapy treatment planning (RTP) and demonstrate the importance of three-dimensional (3D) distortion correction (DC) by quantitatively measuring

Facilitating PTZ Camera Auto-Calibration to Be Noise Resilient With Two Images
IEEE Access, 2019 This paper presents a simple but effective technique to calibrate a PTZ (Pan/Tilt/Zoom) camera by using only two images for five intrinsic parameters: focal length, aspect ratio, the principle point coordinates and the distortion coefficient.
