A Provacative Test to Determine Brain Compliance in the Management of Patients with Hydrocephalus
… sensors and a TMD sensor. A common tilt table apparatus is used to methodically and artificially increase intracranial pressure to stress the cranial system during the test. The results from this test are computed using a digital signal processing algorithm to determine phase …

Physical Modelling of Instability in Granular Soils and Tsunami Hazards Associated with Coastal Slope Failures
… of soil instability. In this study, large-scale tilt table testing under dry and submerged conditions were conducted with imbedded shear stress and strain sensors to quantify the constitutive behaviour and pore pressure response of loosely placed sand leading up to and during instability. …

Cerebrale Blutflussregulation bei orthostatischer Hypotension im Rahmen des Morbus Parkinson
… non-invasive blood pressure measurement on the tilt table. The analysis focused on changes in cerebral blood flow velocity and systemic blood pressure depending on the position. Through spectral analysis of spontaneous oscillations in both signals, the dynamic autoregulation was investigated …

Ultrasound-based Noninvasive Monitoring Methods for Neurocritical Care
… noninvasive, patient-specific, and interpretable fashion. High frequencies (4-6 MHz) were used for extracranial insonation. Vessel diameters were estimated with B-mode images and were combined with color flow derived velocity measurements to yield the volumetric flow rate. B-mode derived …

Einfluss simulierter Mikrogravitation und variabler Kochsalzzufuhr auf arteriellen Blutdruck, Hämodynamik und Orthostasetoleranz gesunder Probanden
… is the consequence. High dosage of salt tablets given directly after residence in microgravity has been shown to be an appropriate measure to ameliorate orthostatic tolerance. Effects of continuously high resp. low salt diet on orthostatic tolerance are unknown yet. As well as the …
