Thermal-Hydraulic Performance of Metal Foam Heat Exchangers
, 2012 Due to their large surface-area-to-volume ratio and tortuous structure, metal foams hold promise for heat transfer applications. Both of these factors increase the heat transfer by enhancing the mixing and surface area.

Monitoring the metal transfer process of GMAW by a simplified laser backlight method
, 2016 Due to its great productivity, Gas metal arc welding (GMAW) has been become the most frequently used automated welding process. Unfortunately, the metal transfer changes from solid to liquid, which causes spatters and fumes.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Advanced Engineering Materials, EarlyView.Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Transference of Heat in Cooled Metals [PDF]
Nature, 1898 SEVERAL observers1 have noticed a rise of temperature at the cooler end of a bar of metal when the hot end was suddenly cooled. As this would be a most surprising effect, and as Johns Hopkins University has been mentioned in connection with the subject, Dr. H. A. Rowland has requested me to examine the matter.
