- A New Islanding Detection Technique for Distributed Generation
- Author: Menon, Vivek Viswanathan
- Date: 2006-05-15
- Program: Electrical Engineering
- Abstract: The phenomenon of unintentional islanding, which occurs when a distributed generator (DG) continues to feed power into the grid when power flow from the central utility source has been interrupted, can result in serious injury to the linemen who are trying to fix the line. Several strategies have been proposed in the past to avoid such an occurrence. Of the existing islanding detection propositions two schemes one of which is an active technique (the positive feedback technique) and the other one a passive technique (the VU and THD technique) are found by the author to be very effective but no...

- Extended Cluster Weighted Modeling Methods for Transient Recognition Control
- Author: Zhu, Tao
- Date: 2006-08-15
- Program: Engineering
- Abstract: This dissertation considers cluster weighted modeling (CWM), a novel nonlinear modeling technique for the electric load transient recognition problem. The
original version of CWM is extended with a new training algorithm and a real-time CWM prediction method. In the training process, a new training algorithm is derived that is a mixture of expectation maximization (EM) – least mean squares (LMS). The algorithm addresses the singular matrix inversion problem in EM. A recursive EM-LMS algorithm is developed that allows the CWM to adapt to time varying systems. In the prediction process,...

- Rotavirus NSP1 is an interferon system antagonist
- Author: Graff, Joel Wallace
- Date: 2008-08-15
- Program: Veterinary Molecular Biology
- Abstract: Rotaviruses cause severe gastroenteritis in mammals, including humans and livestock. Most rotavirus proteins have known functions, either as a mediator of virus replication or as a component of the infectious virus particle. The function of nonstructural protein 1 (NSP1) was unknown. However, it has been suggested that the function of NSP1 involved interactions with cellular proteins. Using the NSP1 encoded by a bovine rotavirus as the bait protein of a yeast-two hybrid interaction trap, interferon regulatory factor 3 (IRF3) was identified as an NSP1-interacting protein. Due to the importance ...

- A Paradigm Shift for the Science Documentary
- Author: Kustusch, Christopher Michael
- Date: 2007-05-15
- Program: Science and Natural History Filmmaking
- Abstract: The science documentary exists within a very specific cultural space. It is not only separate from conventional fictional entertainment but it is also separate from the mainstream, or social documentary, tradition. The cross-blending of genres and the borrowing of technique and style from current "modern documentaries" should lead to a radical reinvention of the paradigm (i.e., a paradigm shift) of the science/natural history documentary. This essay will focus on three main areas of discussion: the rise of the modern documentary, a discussion exploring the characteristics of the curr...

- Identification and Characterization of Novel Protein-Protein Interactions with the Basal Transcription Factor, TATA-Binding Protein
- Author: Prigge, Justin Robert
- Date: 2006-05-15
- Program: Veterinary Molecular Biology
- Abstract: Recruitment of the TATA-Binding Protein, TBP, to the promoter is a critical, rate-limiting step that drives the initial phase of nearly all gene transcription events. Because of this, many transcriptional regulators target TBP, either to localize TBP at the promoter, or to relay signals between other promoter-bound protein complexes and the basal transcription machinery. Studies described herein were designed to identify novel protein-protein interactions with TBP. To do this, we screened mid-gestational pregnancy-associated cDNA prey libraries using two different yeast two-hybrid systems. Scr...

- Novel die-to-die coaxial interconnect system for use in system-in-Package applications
- Author: McIntosh, Christopher Michael
- Date: 2008-12-15
- Program: Electrical Engineering
- Abstract: The electrical parasitics of traditional integrated circuit (IC) packaging methods are a known bottleneck to overall system performance. The parasitic inductance and capacitance of traditional package interconnect such as wire bonds, create noise sources which ultimately limit the speed at which a digital system can run. Recent advances in package interconnect have reduced these parasitics by moving to a system-in-Package (SiP) approach. In SiP, multiple IC dies are connect directly to each other and encapsulated within the same package. This improves performance by eliminating the need for bo...

- Low cost range and attitude determination solution for small satellite platforms
- Author: Greenfield, Nathan Joseph
- Date: 2009-05-15
- Program: Electrical Engineering
- Abstract: The ability to determine the range and attitude between two satellites can be a challenging venture. It can be made more challenging when considering the use of such a system on a small satellite. Successful implementation of a small and low power range and attitude sensor could open potential doors to multiple small satellite constellations and formation flying maneuvers. After successfully demonstrating an electromagnetic docking system on a one-dimensional air track, it was determined that continued work into two and three-dimensional systems would require a more functional range and attitu...

- Date: 2007-12-15
- Program: Neuroscience
- Abstract: An outstanding problem in neuroscience is to describe the relationship between various stimulus sources in the environment and how they are represented by patterns of activity in nervous systems, a problem generically referred to as 'neural coding'. Most previous methods developed to address this problem have assumed a linear relationship between environmental stimuli and neural responses, and generally relied on measures of the mean state of the environment preceding neural activity to characterize the stimulus-response transformation. The goal of this thesis is to develop new methods of char...
