Spot Weld Inspections Using Active Thermography

open access: yesApplied Sciences, 2022
Spot welds have a significant part in the creation of automotive vehicles. Since the integrity of, for example, a car, is dependent on the performance of multiple welds, it is important to ensure the quality of each spot weld.

Dynamic Line Scan Thermography Parameter Design via Gaussian Process Emulation

open access: yesAlgorithms, 2022
We address the challenge of determining a valid set of parameters for a dynamic line scan thermography setup. Traditionally, this optimization process is labor- and time-intensive work, even for an expert skilled in the art.

Thrombolysis for Central Retinal Artery Occlusion in 2020: Time Is Vision!

open access: yesJournal of neuro-ophthalmology, 2020
BACKGROUND Acute nonarteritic central retinal artery occlusion (CRAO) is an eye stroke with poor visual prognosis and no proven effective therapies. Given advances in acute stroke care, thrombolysis in CRAO merits critical re-examination.

Optimisation of a Heat Source for Infrared Thermography Measurements: Comparison to Mehler Engineering + Service-Heater

open access: yesApplied Sciences, 2020
Using an optimised heating source in active thermography can facilitate the processing of measurement results. By designing a custom heat source for dynamic line scan thermography, we reduced the excitation power needed to heat the sample and decreased ...

A Novel Line-Scan Algorithm for Unsynchronised Dynamic Measurements

open access: yesApplied Sciences, 2023
In non-destructive inspections today, the size of the sample being examined is often limited to fit within the field of view of the camera being used. When examining larger specimens, multiple image sequences need to be stitched together into one image ...

Stillbirths: the vision for 2020

open access: yesThe Lancet, 2011
Stillbirth is a common adverse pregnancy outcome, with nearly 3 million third-trimester stillbirths occurring worldwide each year. 98% occur in low-income and middle-income countries, and more than 1 million stillbirths occur in the intrapartum period, despite many being preventable.

Visual Warning Signals Optimized for Human Perception: What the Eye Sees Fastest

open access: yesApplied Bionics and Biomechanics, 2005
This study aimed to answer the question of how to design a visual warning signal that is most easily seen and produces the quickest reaction time. This is a classic problem of bionic optimization—if one knows the properties of the receiver one can most ...
