Elastically Housed Kinematic Couplings for InterchangeableElectric Vehicle Batteries
… could overcome challenges with regard to manufacturing tolerance and operational loads. Accounting for proper preload and compliance for disturbance rejection is critical to maintain sufficient electrical contact while avoiding arcing. Kinematic couplings can provide enough contact area …

Flutter and Forced Response of Turbomachinery with Frequency Mistuning and Aerodynamic Asymmetry
… the single family of modes approach by assuming manufacturing tolerance. The unsteady aerodynamic forces are computed using CFD methods assuming aerodynamic symmetry. The aerodynamic asymmetry is applied by perturbing the influence coefficient matrix. These aerodynamic perturbations influence …

Electromagnetic and Quasi-Optical Analysis of Cavity Coupled Bolometers for Far-Infrared and Terahertz Receivers
… system. The impact of the various potential manufacturing tolerance levels for the feed horn on the predictions of the beam on the sky were also analysed for a millimetre-wave system. The specific example considered was the new 4 mm receiver on the Onsala Space Observatory 20 m …

Enhancing signal to noise ratio for electrostatic transducers
… analysis is utilised to realise a design and manufacturing tolerance requirements. The devices were manufactured in the operating range of 25 kHz to 85 kHz. Air-coupled pulse-echo insertion loss was found to be 61.3 dB, an improvement of 9.1 dB over the conventional cavity only design. Results …

Optimum Control for Minimization of Torque Ripple in Synchronous Reluctance Machines
This thesis provides an analysis for identifying the sources of torque ripple in electric machines. It includes the effect of conductor distribution in the machine, magnet flux density distribution, current harmonics and non-idealities in position and current sensors. Harmonic orders and magnitudes …
