Abstract: The immersedboundary method is coupled to an incompressibleflow Reynoldsaveraged Navier Stokes solver, based on a twoequation turbulence model, to perform unsteady numerical simulations of airflow past the NACA0012 airfoil ...

Abstract: The authors compare several methods to map the a priori tropospheric delay of global positioning system (GPS) signals from the zenith direction to lower elevations. This is commonly achieved with so-called mapping functions. ...

Abstract: In vitro active shoulder motion simulation can provide improved understanding of shoulder biomechanics; however, accurate simulators using advanced control theory have not been developed. Therefore, our objective was to ...

Abstract: Quantitative computed tomography (qCT) relies on calibrated bone mineral density data. If a calibration phantom is absent from the CT scan, post hoc calibration becomes necessary. Scanning a calibration phantom after-the-fact ...

Abstract: An important feature of humeral orthopedic finite element (FE) models is the trabecular stiffness relationship. These relationships depend on the anatomic site from which they are derived; but have not been developed for ...

Abstract: Atmospheric water vapor was measured with six Global Positioning System (GPS) receivers for 1 month at sites in Colorado, Kansas, and Oklahoma. During the time of the experiment from 7 May to 2 June 1993, the area experienced ...

Abstract: tellite data rescue activities uncover dormant records of our recent past. Unavailable back then, powerful methods enable today to assess and utilize early images and soundings for climate studies.
