Measurement of Critical Contact Angle in a Microgravity Space Experiment
Mathematical theory predicts that small changes in container shape or in contact angle can give rise to large shifts of liquid in a microgravity environment. This phenomenon was investigated in the Interface Configuration Experiment on board the NASA USML-2 Space Shuttle flight. The experiment’s “double proboscis” containers were designed to strike a balance between conflicting requirements of ...
متن کاملAutomatic measurement of instantaneous changes in the walls of carotid artery with sequential ultrasound images
Introduction: This study presents a computerized analyzing method for detection of instantaneous changes of far and near walls of the common carotid artery in sequential ultrasound images by applying the maximum gradient algorithm. Maximum gradient was modified and some characteristics were added from the dynamic programming algorithm for our applications. Methods: The algorithm was evaluat...
متن کاملReliable measurement of the receding contact angle.
Surface wettability is usually evaluated by the contact angle between the perimeter of a water drop and the surface. However, this single measurement is not enough for proper characterization, and the so-called advancing and receding contact angles also need to be measured. Measuring the receding contact angle can be challenging, especially for extremely hydrophobic surfaces. We demonstrate a r...

STUDY DESIGN Automatic measurement of Cobb angle in patients with scoliosis. OBJECTIVE To test the accuracy of an automatic Cobb angle determination method from frontal radiographical images. SUMMARY OF BACKGROUND DATA Thirty-six frontal radiographical images of patients with scoliosis. METHODS A modified charged particle model is used to determine the curvature on radiographical spinal i...
متن کاملDetection of pore space in CT soil images
Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract Computed Tomography (CT) images provide a non-invasive alternative for observing soil structures, particularly pore space. Pore space in soil data indicates empty or free space in the sense that no material is p...
