An Optical Measurement System to Measure Velocity and Provide Shock Wave Pressure Diagrams
This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...
متن کاملPulse pressure velocity measurement - a wearable sensor
Pulse pressure velocity measurements (PPV) may be a source of useful information on artery state. A 2007 guideline of the European Society of Hypertension recommends assessing arterial stiffness in patients with arterial hypertension, by measuring the PPV. Mechanical changes in the cardiovascular tree involved in the blood ejection have been measured at the thorax level and on the wrist using i...
متن کاملMeasurement of Upper Air Pressure, Temperature and Humidity
12.1.1 Definitions The following definitions from WMO (1992; 2003a) are relevant to upper air measurements using a radiosonde: Radiosonde: Instrument intended to be carried by a balloon through the atmosphere, equipped with devices to measure one or several meteorological variables (pressure, temperature, humidity, etc.), and provided with a radio transmitter for sending this information to the...
متن کاملMeasurement of Aortic Pressure Wave Velocity by 4D Image Registration
Aortic pulse wave velocity is an important diagnostic measure and has been associated with significant cardiovascular mortality. Our hypothesis is that this parameter can be measured using displacement fields obtained by registration of time-series images. This paper presents a method in which a form of the wave equation is used as a regularization term in the registration process. It is demons...
متن کاملMeasurement and Numerical Simulation of Air Velocity in a Tunnel-Ventilated Broiler House
A building needs to be designed for the whole period of its useful life according to its requirements. However, future climate predictions involve some uncertainty. Thus, several sustainable strategies of adaptation need to be incorporated after the initial design. In this sense, tunnel ventilation in broiler houses provides high air velocity values (2–3 m·s−1) at animal level to diminish their...
