Generalized Intersection Over Union: A Metric and a Loss for Bounding Box Regression [PDF]

Computer Vision and Pattern Recognition, 2019
Intersection over Union (IoU) is the most popular evaluation metric used in the object detection benchmarks. However, there is a gap between optimizing the commonly used distance losses for regressing the parameters of a bounding box and maximizing this ...

The National Aeronautics and Space Administration‐task load index: NASA‐TLX: evaluation of its use in surgery

ANZ journal of surgery, 2022
The technical difficulty an operation creates for a surgeon is difficult to measure. Current measures are poor surrogates. In both research and teaching settings it would be valuable to be able to accurately measure this degree of difficulty.

Mirror formation control in the vicinity of an asteroid [PDF]

, 2008
Two strategies are presented for the positioning and control of a spacecraft formation designed to focus sunlight onto a point on the surface of asteroid, thereby sublimating the material and ejecting debris creating thrust.

Reactant Jetting in Unstable Detonation [PDF]

, 2009
We note the common existence of a supersonic jet structure locally embedded within a surrounding transonic flow field in the hitherto unrelated phenomena of unstable gaseous detonation and hypervelocity blunt body shock wave interaction. Extending prior

Experimental Flow Investigation of a Truncated Ideal Contour Nozzle [PDF]

, 2006
Various tests showed a significant side load peak for low nozzle pressure ratios during engine start-up and shut down phase. DLR Lampoldshausen carried out tests to examine the flow field in a truncated ideal contour nozzle for low NPR.

Validation of the Raw National Aeronautics and Space Administration Task Load Index (NASA-TLX) Questionnaire to Assess Perceived Workload in Patient Monitoring Tasks: Pooled Analysis Study Using Mixed Models

Journal of Medical Internet Research, 2020
Background Patient monitoring is indispensable in any operating room to follow the patient’s current health state based on measured physiological parameters. Reducing workload helps to free cognitive resources and thus influences human performance, which
