Characterization, Processing, and Synthesis of Extreme-Performance Continuous Carbon Nanotube Network Composites
… – and human-scale fiber reinforcements for extreme-performance composites. Yet because the constituent CNTs interact only via intermolecular forces, network properties fall short of their building blocks. Although these materials show promise as reinforcement in composites, the networks’ …

Overcoming electro-thermal barriers to achieve extreme performance power conversion for more electric aircraft
… of one block of this electrical system: a high-performance dc-ac converter designed to drive the type of electric machine engineered for electric flight from a high-voltage dc bus that would be present on some MEA concepts. The flying capacitor multilevel topology is demonstrated as an enabling …

Predicting extreme performers on the JSE securities exchange
… this thesis builds on the prior literature on extreme performance by Reinganum (1988), Glickman, DiRienzo and Ochman (2001), O'Neil (2002) and Dong, Duan and Jang (2003), where an extreme winner (loser) is a stock which at least doubles (halves) in a twelve month period. The research is …

Space-time block coding with imperfect channel estimates
… and with minimal complexity in the receiver. The performance of STBC with perfect channel state information (CSI) being available at the receiver has been shown to provide approximately 10 dB of improvement over uncoded transmission in Rayleigh fading when using Quadrature Phase Shift Keying …

Design and analysis of a quasi-optical beam combiner for the QUBIC CMB interferometer
… the interferometric observing technique, places extreme performance specifications on the QUBIC optics. Fortunately, as we shall show, there are types of well-known re ecting and refracting telescopes that are suitable for QUBIC. In this thesis I propose a design for the quasi-optical combiner …

Hydor-impact, fluid-structure interaction and structural response of modern racing yacht
… the key issues in a modern racing yacht<br/>for extreme performance. As a result, many yachts have experienced various structural<br/>failures caused by the hydrodynamic impact or ’hydro-impact’ phenomenon by<br/>slamming.<br/><br/>The structural failure by hydro-impact originates from the facts …
