We studied the impact of central auditory processing disorder (CAPD) and cognitive deficit (CD) on the self-assessment of hearing handicap in 122 elderly subjects. Self-assessment was quantified by means of the Hearing Handicap Inventory for the Elderly (HHIE). Results showed that cognitive impairment exerted no significant effect on the self-assessment of(More)
This thesis presents high-order, discontinuous Galerkin (DG) discretizations of the Reynolds-Averaged Navier-Stokes (RANS) equations and an output-based error estimation and mesh adaptation algorithm for these discretizations. In particular, DG discretizations of the RANS equations with the Spalart-Allmaras (SA) turbulence model are examined. The dual(More)
We present a p-multigrid solution algorithm for a high-order discontinuous Galerkin finite element discretization of the compressible Navier–Stokes equations. The algorithm employs an element line Jacobi smoother in which lines of elements are formed using coupling based on a p = 0 discretization of the scalar convection–diffusion equation. Fourier analysis(More)

A high-order discontinuous Galerkin finite element discretization and p-multigrid solution procedure for the compressible Navier-Stokes equations are presented. The discretization has an element-compact stencil such that only elements sharing a face are coupled, regardless of the solution space. This limited coupling maximizes the effectiveness of the(More)
This paper stresses the relatively high prevalence of auditory abnormality in multiple sclerosis. An auditory test battery consisting of the acoustic reflex (AR), the auditory brainstem response (ABR), the masking level difference (MLD) and speech audiometry (SA) was administered to 62 patients with diagnosed 'definite' multiple sclerosis. The AR showed the(More)
Two problems in the clinical measurement of acoustic reflex latency are discussed. First, the rise characteristic of the reflex is affected by the frequency of the eliciting signal. Due to the closed ipsilateral feedback loop system the reflex rises more rapidly at low frequencies than at high frequencies. Second, the temporal characteristic of the(More)
An adaptive method for high-order discretizations of the Reynolds-averaged Navier-Stokes (RANS) equations is examined. The RANS equations and Spalart-Allmaras (SA) turbulence model are discretized with a dual consistent, discontinuous Galerkin discretiza-tion. To avoid oscillations in the solution in under-resolved regions, particularly the edge of the(More)
