This paper describes a calibration method for inertial and magnetic sensors using a batched optimization procedure. Well estab- lished sensor, motion and constraint models are applied which include sensor gains, biases, misalignments and inter-triad misalignments. For the magnetometer, hard and soft …

Claustrofobie treedt vaak op bij personen die een MRI-onderzoek (magnetic resonance imaging) moeten ondergaan. De smalle en lange tunnel, de herrie en het stilliggen zijn factoren die claustrofobie veroorzaken. Onderzoek toont aan dat 35% van de patiënten claustrofobische reacties ervaart tijdens een …

Background: Magnetic resonance imaging (MRI) is being used extensively in the search for pathoanatomical factors contributing to low back pain (LBP) such as Modic changes (MC). However, it remains unclear whether clinical findings can identify patients with MC. The purpose of this explorative study was …

The demand of renewable energy in the European Union is increasing significantly in order to reduce CO2 emissions. Efforts are being made for further development of biomethane and hydrogen to use it as a clean and sustainable fuel for vehicles. However, biomethane and hydrogen contains impurities that …

Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) is een non-invasieve behandelmethode voor symptomatische uterus myomatosus. In dit onderzoek is de voorspellende waarde van multiparametrische MRI karakterisatie onderzocht op het technisch behandelresultaat van MR-HIFU. De SSI en …

We report on a first field test in which miniaturized sensor motes were used to explore and inspect an operational pipeline by performing in situ measurements. The spherical sensor motes with a diameter of 39 mm were equipped with an inertial measurement unit (IMU) measuring 3-D acceleration, rotation, …

Multiple scientific and industrial applications such as telecommunication and quantum cryptography causing a rise in the development of the superconducting nanowire single photons detectors (SNSPD). In the last decade, the characteristics of the detectors improved but run against the problem that the …

Kinematical joint analysis during road cycling is a new trend. Reviewing the methods for 2D and 3D lower limb kinematical research, the sensor to segment alignment appeared to be the most challenging part due to unknown orientation with respect to the anatomical joints. A methodology that is suitable …
