Calibration and Validation of a SWAT model for the quantification of water provision ecosystem service for the Conservation Area of Guanacaste
DownloadFall 2021
Water is considered a cross-cutting resource for all the ecosystem services (ES) types, namely: for the provision of drinking water and food; regulation through flood control; guarantee of a suitable habitat for fauna and flora; and inspiration for many cultures and their intangible heritage...

Characterization and Control of Cyclic Variability in a Gasoline/Natural Gas Dual-Injection Spark Ignition Engine
DownloadSpring 2016
Reducing the cyclic variability of a gasoline/natural gas dual injection spark ignition engine using minimum variance control is the subject of this thesis. Cylinder pressure is used to calculate four combustion metrics, the standard deviation of which is used as an indicator of cyclic...

Children’s and Fathers’ Perceptions of Fathers’ Use of Structure, Negative Control, and Autonomy Support
DownloadSpring 2017
The current study investigated fathers’ and children’s perspectives of fathers’ use of structure, negative control, and autonomy support parenting behaviours in relation to children’s internalizing, externalizing, and adaptive behaviours, and father-child attachment. Researchers interviewed 55...

Comparison of the open‐closed separatrix in a global magnetospheric simulation with observations: The role of the ring current
Download2010
Kabin, Konstantin, Lu, J. Y., Rankin, Robert, Gombosi, Tamas I., Watt, Clare E. J., Ridley, Aaron J., Toth, Gabor, Milan, Steve E., Zhang, Jichun, Rae, I. Johnathan, Clauer, C. Robert, De Zeeuw, Darren L., Fenrich, Frances
The development of global magnetospheric models, such as Space Weather Modeling Framework (SWMF), which can accurately reproduce and track space weather processes has high practical utility. We present an interval on 5 June 1998, where the location of the polar cap boundary, or open-closed field...

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,...
