Design and Implementation of a Pivot Shift Prototype for Quantitative Analysis
… gyroscopes to provide force, orientation, and acceleration measurement. The prototype has been used to quantify the results of a medical test called pivot shift which tests the dynamic stability of the patients knee. With the initial prototype built, limited clinical trials were conducted. Two …

Design and implementation of a preload electronics architecture for a MEMS accelerometer
… mass of the sensor and providing an accurate acceleration measurement. This architecture is compared to alternative methods of linearizing the control loop. The electronics system is divided into analog and digital subsystems. The design is analyzed at several abstraction levels. The system is …

Toward a demonstration of a Light Force Accelerometer
… optically confines a glass microsphere. Inertial acceleration of the device results in microsphere displacement along the sensitive axis, which is subsequently nulled by optical forces to provide an acceleration measurement. A simple calculation that takes into account fundamental noise processes …

Study of hypersonic aerodynamics using free flight experiments
… numerically and validated with force balance measurements on fixed, sting-mounted models in wind tunnels. However, the results can be challenging to resolve and are unavoidably compromised by sting interference. This thesis describes experimental studies conducted using the University of …

Generalized modelling of a space station and determination of the transfer function
… between astronaut force inputs and station acceleration outputs is postulated. The validity of this transfer function can then be examined using the experimental force and acceleration data collected from Mir from the period of 1996 to 1998. In order to quantify astronaut-induced …

THE DESIGN AND IMPLEMENTATION OF A SYSTEM FOR MACHINE MONITORING
… of the VA sensor was 1kHz with an amplitude of acceleration within the ±16g range. The resolution of the acceleration measurement was 3.9mg which was 0.02% of the established 20g measuring range. The conditions of the motors were determined by programming which was precise to 3dp. The …

Intelligent Flight Control Systems Using Adaptive Deep Neural Networks and Concurrent Learning-Based Design Methods
… development formally incorporating realistic measurement errors in the recorded data stack; a Lyapunov-based stability analysis deriving a sufficient condition on the diversity of the recorded data stack under which the tracking error and DNN weight estimation error are proven to be uniformly …

Microstructure characterization of foamed cement and concrete
… consolidating effect was characterized based on acceleration measurement in the fresh mixtures during vibration and the hardened air-void parameters prescribed by ASTM C457 were also estimated using an automated flatbed scanner method. There was no significant change in the spacing factors of the …

Design and application of a novel Laser-Doppler Velocimeter for turbulence structural measurements in turbulent boundary layers
… to acquire fully-resolved turbulence structural measurements in high Reynolds number two- and three-dimensional turbulent boundary layers. The new instrument combines, for the first time, new techniques allowing for the direct measurement of particle acceleration and sub-measurement-volume-scale …
