Methods: We examined sex differences in the association between PF and HRQL among older adults. One hundred eight adults (ages 60 to 98 years) completed the Continuous Scale-Physical Function Performance test (CS-PFP10), Functional Status Index (FSI), and SF-36. Effects of sex and fitness group on SF-36 scores were examined by using linear and nonparametric techniques. Regression techniques wer...

Since the 1980’s, depleted uranium (DU) has been the primary material used by the US military in armorpiercing rounds. Domestic firing ranges that have been used for DU munitions training purposes are located around the country and have varying extents of contamination by other types of projectiles. A project is underway to develop a set of sensors to locate expended DU rounds and to process so...

This paper uses a divergence-conforming B-spline fluid discretization to address the long-standing issue of poor mass conservation in immersed methods for computational fluid-structure interaction (FSI) that represent the influence of the structure as a forcing term in the fluid subproblem. We focus, in particular, on the immersogeometric method developed in our earlier work, analyze its conver...

A detailed study of the effect of the η-nucleus final state interaction (FSI) in the p d → He η reaction close to threshold is presented. The FSI is incorporated through a T-matrix for η He elastic scattering, constructed using few body equations. This T-matrix accounts for off-shell and binding effects in η-nucleus scattering. The energy dependence of the data on the p d → He η reaction near t...

In this paper higher order implicit Runge-Kutta schemes are applied to fluid-structure interaction (FSI) simulations. A staggered approach with a structural predictor is applied to an FSI problem. The equations governing the dynamics of the structure are integrated in time by the Explicit Single Diagonal Implicit Runge-Kutta (ESDIRK) schemes and the arbitrary high order finite volume scheme is ...

Due to the significant health and economic impact of blood vessel diseases on modern society, its analysis is becoming of increasing importance for the medical sciences. The complexity of the vascular system, its dynamics and material characteristics all make it an ideal candidate for analysis through fluid-structure interaction (FSI) simulations. FSI is a relatively new approach in numerical a...

Atmospheric CO2 concentrations, retrieved from spectral measurements made in the near infrared (NIR) by the SCIAMACHY instrument, using a new retrieval algorithm called Full Spectral Initiation Weighting Function Modified Differential Optical Absorption Spectroscopy (FSI WFM-DOAS), are compared to ground based Fourier Transform Infrared (FTIR) data and to the output from a global chemistry-tran...

An important eld in computational science and engineering is the simulation of the coupled problem of uid ow interacting with a moving structure. A common notation for this is uid-structure interaction (FSI) problems, which include both aeroelasticity and hydroe-lasticity. Herein we give an overview of results obtained within Fluid-Structure Interaction-Structural Design (FSI-SD) a project that...

We study a 3D fluid-structure interaction (FSI) problem between an incompressible, viscous fluid modeled by the Navier-Stokes equations, and the motion of an elastic structure, modeled by the linearly elastic cylindrical Koiter shell equations, allowing structure displacements that are not necessarily radially symmetric. The problem is set on a cylindrical domain in 3D, and is driven by the tim...

Abstract Background Patient-specific active fluid–structure interactions (FSI) model is a useful approach to non-invasively investigate the hemodynamics in heart. However, it takes lot of effort obtain proper external force boundary conditions for models, which heavily restrained time-sensitive clinical applications computational models. Methods The simulation results 12 passive FSI models base...
