Spring 2016
A dual-fuel system is used to control HCCI combustion timing and load in a CFR engine. The systems steady-state response to iso-octane and n-heptane injected energy is investigated then a dynamic ARMAX model is found using system identification. This model is used to design a norm-optimal...

Minimizing invasion risk by reducing propagule pressure: a model for ballast-water exchange
Download2005-01-01
Lewis, Mark A., Wonham, Marjorie J., MacIsaac, Hugh J.
Biological invasions are a major and increasing agent of global biodiversity change. Theory and practice indicate that invasion risk can be diminished by reducing propagule pressure, or the quantity, quality, and frequency of introduced individuals. For aquatic invasions, the primary global...

In this thesis, methods for improving needle steering during prostate brachytherapy are studied. Brachytherapy is a minimally-invasive, out-patient therapy for prostate cancer treatment with a fast recovery time. Success of brachytherapy depends on precise placement of needle tips in pre-planned...

Modeling the transport of cryoprotective agents in articular cartilage for cryopreservation
DownloadSpring 2011
Loading vitrifiable concentrations of cryoprotective agents is an important step for cryopreservation of biological tissues by vitrification for research and transplantation purposes. This may be done by immersing the tissue in a cryoprotective agent (CPA) solution, and increasing the...

Nano-scale studies of the assembly, structure and properties of hybrid organic-silicon systems
DownloadFall 2011
Advancements in the field of electronics might be achieved by future molecular scale devices. Hybrid organic-silicon structures have the potential to overcome many challenges facing the use of molecules as devices while maintaining the ability to interface with traditional silicon technology. The...

Needle Shape Visualization, Tracking and Steering Control for Permanent Prostate Brachytherapy Applications
DownloadFall 2016
Prostate cancer is one of the most prevalent types of cancers in North American males, afflicting one in eight men over the course of their lifetime. Fortunately, early-stage prostate cancer has a wide variety of treatment options. One such option, permanent prostate brachytherapy, has been...

Non-linear reparameterization of complex models with applications to a microalgal heterotrophic fed-batch bioreactor
DownloadSpring 2010
Good process control is often critical for the economic viability of large-scale production of several commercial products. In this work, the production of biodiesel from microalgae is investigated. Successful implementation of a model-based control strategy requires the identification of a model...

Nonlinear state-space control design for displacement-based real-time testing of structural systems
DownloadSpring 2011
Moosavi Nanehkaran, Seyed Abdol Hadi
This study presents the nonlinear design of a state space controller to control hydraulic actuators under displacement control, specifically for real-time pseudo-dynamic testing applications. The proposed control design process uses the nonlinear state space model of the dynamics of the system to...
