The density of a liquid (12) in a container (10) is measured by means of a transmitter (14) and a receiver (16) and ultrasonic circuits (18-22) for measuring the associated speed of sound in the liquid (12). This information is combined with the liquid temperature measured by a senso...
The choice practically lies between defining mass by inertia at a given speed or by gravity. ... As, however, gravity depends on local circumstances, while inertia (at given velocity) does not, the latter property is preferred for the definition of mass, as being more fundamental.'' So ...
The invention relates to a geodetic aircraft instrument for gravity measurement with the aid of an aircraft specially equipped for the purpose, and a method for this measurement, according to which the aircraft is stabilised with regard to speed, heading and flying altitude, and the gravimeter has...
Another approach is to establish a water balance at a node that incorporates the addition of a known flow rate of pure water. This is particularly appropriate for gravity units, which routinely use the addition of fluidization water to improve selectivity (e.g., jigs and most semicontinuous ...

The pH values of aqueous solutions are conventionally measured with pH-sensitive electrodes such as glass electrodes or ion-sensitive field-effect transistors (ISFETs) used in conjunction with Ag/AgCl reference electrodes and KCl solutions. The speed of pH measurement with these systems can be defici...
load on the vehicle is higher than the vehicle's gravity centre. This study is relevant for studying the local wind environment, driving safety, and serviceability of long-span bridges in mountainous areas. Introduction Investigation of the wind characteristics over the bridge deck has attracted ...
Monitoring joystick operations in power wheelchairs (PWCs) is promising for investigating user-wheelchair interaction and providing quantitative measures to assess the user’s driving performance. In this paper, an add-on measurement system, Power Wheelc
However, there are several limitations, such as high operating costs, the need for a laboratory and a specialist to operate the system, and long preparation time. This paper presents the development of a low-cost portable gait measurement system by using the integration of flexible force sensors...
