Measuring quality indicators of liquids by means of optical fiber absorption spectroscopy in a wide spectral range Vrije Universiteit Brussel
Absorption spectroscopy in the wide 200-1700 nm spectral range is carried out by means of optical fiber instrumentation to achieve an optical signature for a digital mapping of liquids according to their differences or similarities. Extra virgin olive oils from different Italian regions and lubricant oils from turbines with different degrees of degradation were considered as dasia case studies psila . The spectral data were processed by means of ...
Pelvic tilt : reliability of measuring the standing position and range of motion in adolescent athletes Universiteit Gent
Monitoring Gas Emissions in Open-circuit Chambers with a Measuring Device that can be used for Measuring of Emissions from Manure Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
To study animal emissions and possible shifts from rumen to manure, we built six open-circuit respiration chambers that are flexible and modular. In addition to methane, we also monitor carbon dioxide, nitrous oxide and ammonia in the chambers. For certain trials, measuring these gases in the manure could also be interesting; therefore, we constructed manure trays in the chambers. By fitting the manure trays with wheels, we facilitated quick and ...
Time of flight distance sensor with enhanced dynamic range Vrije Universiteit Brussel
A Time-Of-Flight distance measurement sensor is presented.
Detection and mixing is done with an in-substrate Current Assisted Photonic
Demodulator. Background light suppression and high dynamic range is
achieved using a Variable Transimpedance Amplifier. The pixel also comprises
sample and hold circuitry and special low pass filters, for in-pixel averaging,
with a 10 Hz to 10 kHz tuneable cut-off frequency. ...

A CAPD based time-of-flight ranging pixel with wide dynamic range Vrije Universiteit Brussel
An in depth view is given of time-of-flight distance sensor and read-out circuit implementations. The sensor is a current assisted photonic demodulator, using majority currents to accelerate generated minority carriers towards the detecting junctions, and combines an effcient mixer with a sensitive detector. Single ended and differential confgurations of the structure are illustrated. Measurements show a quantum effciency of 58%, a DC ...
Concurrent validity and interrater reliability of a new smartphone application to assess 3D active cervical range of motion in patients with neck pain Vrije Universiteit Brussel
Background: There is a lack of valid, reliable, and feasible instruments for measuring planar active cervical range of motion (aCROM) and associated 3D coupling motions in patients with neck pain. Smartphones have advanced sensors and appear to be suitable for these measurements. Objectives: To estimate the concurrent validity and interrater reliability of a new iPhone application for assessing planar aCROM and associated 3D coupling motions in ...
