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 …

To analyze on-water rowing performance, a valid determination of the power loss due to the generation of propulsion is required. This power los can be calculated as the dot product of the net water force vector ( ~ F w;o ) and the time derivative of the position vector of the point at the blade where …

Research was conducted to enable remote control of a humanoid robotic arm using movements of the human arm. Several options for the measurement technique have been discussed, resulting in a proposal for usage of MARG sensor modules to measure human arm movement. The InvenSense MPU9250 sensors where used, …

Background: Osteoarthritis (OA) is the most common rheumatic disease of the musculoskeletal system, with the knee as the most affected joint. The number of people with OA of the knee is likely to increase due to the ageing society and the obesity epidemic. The predominant clinical symptom of knee OA …

In leaving the more traditional territories of the concert performance for broader societal contexts, professional musicians increasingly devise music in closer collaboration with their audience rather than present it on a stage. Although the interest for such forms of devising co-creative musicking …

Purpose: Measurement of muscle mass is paramount in the screening and diagnosis of sarcopenia. Besides muscle quantity however, also quality assessment is important. Ultrasonography (US) has the advantage over dual-energy X-ray absorptiometry (DEXA) and bio-impedance analysis (BIA) to give both quantitative …

Electrohydrodynamic atomization (EHDA) is a technique which uses the influence of strong electric fields to manipulate the break-up of a liquid, pumped through a capillary nozzle, into droplets. In this work, an extended description of a specific high flow EHDA mode, known as the simple-jet mode, is …

Mechanical power output is a key performance-determining variable in many cyclic sports. In rowing, instantaneous power output is commonly determined as the dot product of handle force moment and oar angular velocity. The aim of this study was to show that this commonly used proxy is theoretically flawed …

Introductie: Proprioceptie van het enkelgewricht speelt volgens verschillende studies een belangrijke rol bij balans tijdens vele functionele activiteiten. Joint Position Sense (JPS) is een onderdeel van proprioceptie. Een manier om de JPS, en zodoende proprioceptie, in kaart te brengen is de Ankle Angle …
