Improving quality on a nonwovens line
… on the quality measures--air permeability, caliper, basis weight, and appearance--of the filter media. Then a second experiment was run to study fewer variables in more detail. The data were interpreted with ANOVA and regression models. This research makes three general contributions: a …

The validity of percent body fat estimates by Jackson & Pollock skinfold equation, near infrared, bioelectrical impedance and body mass index
… abdomen and thigh using the Harpenden skinfold caliper. The Jackson & Pollock sum of four skinfold equation was used to calculate percent body fat. Infrared interactance was determined on a Futrex 5000 measured at the biceps halfway between the axillary fold and the anticubital space. …

Range of and relationships between physical and hydraulic properties of commonly available denitrifying bioreactor woodchips
… axis of individual woodchip particles with a caliper. High compaction methods limited the range and magnitude of Ksat for 20 typical woodchip types to 0.10 to 2.05 cm s-1. Reduced compaction increased Ksat and drainable porosity for a subset of woodchips to values closer to current practice …

Digital State Models for Infrastructure Condition Assessment and Structural Testing
… comparison to traditional sensors (e.g., digital caliper, crack microscope, wire potentiometer). Overall, features measured from the 3D point clouds data presented a maximum error of ±0.10 in. (±2.5 mm); and surface features (i.e., crack widths) measured from the texture information in textured …

An image processing technique for erosion analysis on compressor blade geometry
… to the value collected from a 10 µm resolution caliper. Furthermore, image registration showed substantial span-wise leading edge erosion at the 1st-stage rotor and the start of trailing edge erosion at the tip - which amounted to a ∼13% decrease of total chord - after a particle exposure of 1.3 …

Comparing Different Methods of Applying Propensity Score in Controlling Selection Bias for Studies of Prostate Cancer
… methods, matching (greedy matching and caliper matching) produced the estimates that were closest to the estimates when the removed confounder was included in both scenarios. Covariate adjustment and stratification yielded similar controlling effects in both scenarios. Inverse …
