Magnetic bearing systems have received much attention in the research community for the past decades. Its inherent nonlinearity and open-loop instability present challenges for controller design. This thesis investigates and designs model predictive control (MPC) systems for an experimental Active Magnetic Bearing (AMB) laboratory system. A host-target development environment of real-time control system with hardware in the loop (HIL) is used for implementation of the predictive control systems. In this thesis, both continuous and discrete time model predictive controllers are studied.

This thesis investigates the SPH capability available in the commercial Finite Element (FE) code LS-DYNA®, for water impact problems. Experiments have been conducted on rigid wedges impacting water, which were then simulated with the SPH method. Although certain limitations were experienced with the experimental results, a positive correlation was observed with the numerical technique, thus establishing SPH as a promising method for crashworthiness design.

This research examines how parametric loudspeakers may be considered unique acousmatic musical instruments; how the parametric acoustic array (PAA) can potentially make new forms of music and listening experiences; and how PAA-design problems can be overcome. Interdisciplinary in nature, the study uses grounded theory and experimental music practice within a design research methodology. Theory emerges from data, in concert with analysis and framing that draws on areas such as electroacoustic music, spatial composition, acoustics, PAA science/theory, modulation theory, and medium theory.

The python program ARIADNE is a tool developed for evaluators to estimate detailed uncertainties and covariances for experimental data in a consistent and efficient manner. Currently, it is designed to aid in the uncertainty quantification of prompt fission neutron spectra, and was employed to estimate experimental covariances for CIELO and ENDF/B-VIII.0 evaluations.

Experimental autoimmune encephalomyelitis can be induced in susceptible animals by immunodominant deter-minants of myelin basic protein (MBP). To characterize the molecular features of antigenic sites important for designing experimental autoimmune encephalomyelitis suppressing molecules, we report structural studies, based on NMR experimental data in conjunction with molecular dynamic simulations, of the potent linear dodecapeptide epitope of guinea pig MBP, Gln74-Lys75-Ser76-Gln77-Arg78-Ser79-Gln80-Asp81-Glu82-Asn83-Pro84-Val85 [MBP(74–85)], and its antagonist analogue Ala81MBP(74–85)....

Malaria vaccine discovery and development follow two principal strategies. Most subunit vaccines are designed to mimic naturally acquired immunity that develops over years upon continuous exposure to Plasmodiumtrans-mission. Experimental model vaccines, such as attenuated live parasites and transmission-blocking antigens, induce immune responses superior to naturally acquired immunity.
