Control, Modulation, and Protection Strategies for Modular Multilevel Converters in Smart AC and DC Grids Applications
DownloadFall 2017
The technical viability of the modular multilevel converter (MMC) technology for a wide range of applications from low- to high-voltage systems has resulted in the rapid deployment of these converters in smart ac and dc grids. The features that MMCs offer, including common dc-link, modularity,...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...

Effects of Negative Valve Overlap on HCCI Combustion and its use in the Control of HCCI Combustion Timing
DownloadFall 2014
Homogeneous charge compression ignition (HCCI) combustion can produce higher efficiencies and lower emissions when compared to tradition spark or compression ignition engines. This study reports an experimental investigation into the effects of valve timings on HCCI combustion conditions. Using a...

Estimation, Soft Sensing and Servo-control of Linear Distributed and Lumped Parameter Systems
DownloadFall 2021
State-of-the-art advancements in the realm of industrial process control and monitoring often require accurate descriptions of complex processes and their dynamical behaviours. Usually, many industrial processes are described by partial differential equations (PDE) or ordinary differential...

Eustatic and Tectonic Controls on the Development of the Stratigraphic Architecture of the Cayman Islands, British West Indies
DownloadFall 2019
The Paleogene to Neogene carbonate sedimentary successions that form the cores of each of the Cayman Islands, which are located within 150 km of each other, developed on isolated banks that were surrounded by deep oceanic water. Although each of the Cayman Islands has experienced uniform changes...
