Non-invasive Measurement of Cholesterol in Human Blood by Impedance Technique: an Investigation by Finite Element Field Modelling
… in human blood non-invasively by electrical impedance technique. The main part of this research is focused on the development of methodologies for numerical finite element (FE) modelling of simplified blood-cholesterol system, representing a real measurement system. This has been done first …

Development of a Self-Sensing and Self-Healing Bolted Joint
… In order to detect looseness in a joint the impedance health monitoring method is used. A new method of making impedance measurements for health monitoring that greatly reduces the equipment cost and equipment size was developed. This facilitates implementation of the impedance technique in …

The development of a neonatal vital signs database
… waveforms and respiration waveforms using the impedance technique. When possible, percentage oxygen saturation was also captured. The database contains 509 documented clinical records obtained from 35 patients and 20 records containing examples of technical alarm conditions and high frequency …

Advancing Autonomous Structural Health Monitoring
… All the research is based on developing the impedance method for monitoring structural health. The impedance technique utilizes piezoelectric patches to interrogate structures of interested with high frequency excitations. These patches are bonded directly to the structure, so information …

Auswirkungen von Propofol und Fentanyl auf die gastroduodenale Motilität bei Schweinen gemessen mit der multiplen intraluminalen Impedanzometrie
… motility of awake pigs using the intraluminal impedance technique. After conditioning the pigs for nine days, they were instrumented with a central venous catheter, a percutaneous enterogastrostomy (PEG) and an impedance catheter, which was introduced via the PEG into the duodenum through …

MICROWAVE STUDY OF THE PROPERTIES OF UNCONVENTIONAL SUPERCONDUCTING SYSTEMS
Microwave techniques have been widely used to characterize properties of conventional superconducting systems. Examples include characterizing the magnetic penetration depth of bulk crystals and thin films, residual resistance of superconducting radio-frequency cavity systems for use in particle …

A study of the oxygen electrochemistry of ruthenium and iridium
… was investigated using potential step and a.c. impedance technique. Earlier suggestions that the effect is due to catalysis by metal ions in solution were proved to be incorrect and it was shown that ruthenium species were incorporated into the surface oxide film. Changes in the oxidation state …
