Show moreThe simulation of electrical power system dynamic behavior is done using tran- sient stability simulators (TS) and electromagnetic transient simulators (EMT). A Transient Stability simulator, running at large time steps, is used for studying rela- tively slower dynamics e.g. electromechanical interactions among generators and can be used for simulating large-scale power systems. In contrast, an electromagnetic transient simulator models the same components in finer detail and uses a smaller time step for studying fast dynamics e.g. electromagnetic interactions among power electronics devices. Simulating large-scale power systems with an electromagnetic transient simulator is computationally inefficient due to the small time step size in- volved. A hybrid simulator attempts to interface the TS and EMT simulators which are running at different time steps. By modeling the bulk of the large-scale power system in a transient stability simulator and a small portion of the system in an electromagnetic transient simulator, the fast dynamics of the smaller area could be studied in detail, while providing a global picture of the slower dynamics for the rest of power system. In the existing hybrid simulation interaction protocols, the two simulators run independently, exchanging solutions at regular intervals. However, the exchanged data is accepted without any evaluation, so errors may be introduced. While such an explicit approach may be a good strategy for systems in steady state or having slow variations, it is not an optimal or robust strategy if the voltages and currents are varying rapidly, like in the case of a voltage collapse scenario. This research work proposes an implicitly coupled solution approach for the combined transient stability and electromagnetic transient simulation. To combine the two sets of equations with their different time steps, and ensure that the TS and EMT solutions are consistent, the equations for TS and coupled-in-time EMT equations are solved simultaneously. While computing a single time step of the TS equations, a simultaneous calculation of several time steps of the EMT equations is proposed. Along with the implicitly coupled solution approach, this research work also proposes to use a three phase representation of the TS network instead of using a positive-sequence balanced representation as done in the existing transient stability simulators. Furthermore a parallel implementation of the three phase transient stability simulator and the implicitly coupled electromechanical and electromagnetic transients simulator, using the high performance computing library PETSc, is presented. Re- sults of experimentation with different reordering strategies, linear solution schemes, and preconditioners are discussed for both sequential and parallel implementation.

Show moreVibrational control is a method for modification of dynamic properties of linear and nonlinear systems by introduction of fast, zero-average oscillations in a system's parameters. It has been previously shown that forced oscillations introduced in the reactant flow rates to a continuous stirred tank reactor (CSTR) cause a modification of theS- shaped steady-state curve. In the present note experimental evidence is given to show that this modification leads to the operation the CSTR at an asymptotically stable periodic regime located near an unstable steady-state of the reactor system having fixed flow rates. For a given average stabilized state, such a stabilizing mechanism results in a higher production rate or lower energy expenditure compared to a steady operation with shifted input conditions.

Title: IMPROVED SPATIAL-TEMPORAL RECONSTRUCTION FOR CARDIAC AND RESPIRATORY GATED SPECT
Creator: Qi, Wenyuan

Description: Myocardial perfusion single photon emission computed tomography (SPECT) is an important imaging technique for evaluating coronary artery...
Show moreMyocardial perfusion single photon emission computed tomography (SPECT) is an important imaging technique for evaluating coronary artery disease. It can provide information of both myocardial perfusion and ventricular function. However, SPECT images su er from both cardiac and respiratory motion blur. In order to reduce the motion degrading, cardiac and respiratory gated SPECT imaging is used. In gated SPECT imaging, due to the lowered counts, the gated images will be more noisy than the ungated ones. Spatiotemporal (4D) processing is often used to reduce the noise level in gated images. In this thesis, we aim to investigate spatial and temporal processing techniques for improving the quality in cardiac and respiratory gated SPECT imaging. First, we will investigate a piecewise spatial smoothing prior based on totalvariation (TV) in 4D cardiac SPECT image reconstruction. In previous studies, it was found that spatial smoothing could adversely a ect the accuracy of 4D reconstruction in cardiac gated SPECT when temporal smoothing was applied, even though it could suppress the noise level. Our goal is to explore whether a piecewise spatial smoothing prior will improve the image accuracy while reducing the noise. Toward this goal, we will compare TV based piecewise spatial smoothing with quadratic spatial smoothing with simulated imaging, in which we will evaluate the lesion detectability. Clinical data will also be used to compare the results as a preliminary test. Motion-compensated temporal smoothing is known to play a key role in 4D cardiac gated SPECT reconstruction. Next, we will investigate whether better motion estimation could further improve the accuracy of reconstructed images. We will consider two di erent motion estimation models and the known motion in simulated experiments. The motion estimation methods are the classic optical ow estimation (OFE) and a periodic motion estimation method. We will evaluate the reconstruction from di erent motion models using several numerical quanti cation metrics. Furthermore, we will demonstrate reconstruction with the two motion estimation models using clinical acquisitions. Respiratory motion is known to cause motion blur in SPECT image reconstruction, and respiratory gated SPECT imaging can be e ective to combat its e ect. We will develop reconstruction techniques in respiratory gated SPECT. We will consider two reconstruction schemes for respiratory gated SPECT. The rst scheme is a post motion compensated reconstruction, in which images at di erent respiratory phases are reconstructed seperately, and afterwards are averaged over all the respiratory gates by motion compensation. The second scheme is a model based motion compensated reconstruction approach, in which one reference gate is used to describe the acquisition data of all the respiratory gates. Due to irregular respiratory motion, the data acquisition in each respiratory gate is not uniformly distributed among the acquisition angles, which would lead to limited-angle artifacts. To correct such artifacts, we propose an angle compensation method in the reconstruction. In order to deal with both cardiac and respiratory motion, we will investigate a 4D reconstruction approach for dual cardiac-respiratory gated SPECT reconstruction. This approach can accommodate the acquired data simultaneously from di erent cardiac and respiratory gates. It can exploit the correlation in the signal component among both the cardiac and respiratory phases. Both simulated experiments and clinical reconstruction will be used for evaluating this reconstruction approach. Due to the radiation risk of myocardial perfusion imaging (MPI) scans, there is an urgent need to lower the radiation dose used in SPECT. However, lower radiation dose will lead to more noisy reconstruction, which is even more serious in gated SPECT. We would explore the potential of using 4D reconstruction for lowering the dose in dual cardiac-respiratory gated SPECT.

Show moreWith increased diversity in the U.S. workforce, there has become a greater need for organizations to defend against accusations of discrimination and thus a need to produce more accurate adverse impact statistics in discrimination cases. The purpose of the present study is to investigate two adjustments to a confidence interval procedure for calculating adverse impact to see if they give more adequate performance over the unadjusted Morris and Lobsenz (2000) confidence interval procedure. A Monte Carlo simulation revealed that using an adjustment for small sample sizes alleviates some of the problems found for the confidence interval procedure found in previous research. Specifically, adding a 0.5 adjustment to the confidence interval procedure increases the accuracy over the unadjusted procedure and the Agresti and Caffo (2000) procedure. Implications for practioners and researchers are included in the discussion.

Show moreThe sense of smell allows an organism to be aware of the chemical information of the external world. In most land animals, the olfactory system enables the perception of both volatile chemicals, as well as pheromones--chemicals released by animals that regulate their social activities. Among several factors that mediate olfaction, connexin 36 (Cx36), a subunit of gap junctions, has been suggested to play a crucial role in the olfactory system. In the research presented herein, I performed habituation/dishabituation studies on both Cx36 knockout (Cx36 KO) and wild-type mice to determine their exploration patterns towards four odorants. The results indicate that Cx36 KO and wild-type mice behaved differently when they were given defined odorants. In general, Cx36 KO mice spent more time exploring odorants. Cx36 KO and wild-type mice also exhibited different detection threshold towards given odorants. Moreover, cross-habituation between benzaldehyde and octaldehyde was established in Cx36 KO mice at the concentration of 10-4%, which was different from that in wild-type mice. These results may suggest important functions of Cx36 gap junctions in odor detection and integration in mammals. Keywords: Connexin 36, gap junction, olfactory system, habituation/dishabituation

Show moreCancer continues to be the second leading cause of death in the world with one in two individuals suffering from some form of cancer within their lifetimes [1]. The main objective in most cancer therapies is to achieve a complete resection of the cancerous cells, which in surgical approaches is evident from the diagnosis of positive resection margins during postoperative pathology. However, pathological analysis is performed after the patient has been discharged. Thus technologies capable of identifying tumor margins in resected samples intraoperatively could substantially reduce the psychological and economical burden of “call-back” surgeries. As a step in this direction, a wide-field Raman spectroscopy system was employed, which has the capacity to discriminate between tumor and healthy tissue through a “dual-tracer” staining approach within the surgical window. The approach entails dipping the resected tissue in two tracers: one targeted to a cancer specific cell-surface receptor, and another left “untargeted”. In this experiment human glioma (U251) and human epidermoid (A431) tumors were grown subcutaneously in ten nude athymic mice. The data obtained from the Raman spectra of different tissue specimens were then analyzed through tracer kinetic modeling to quantify cancer molecule abundance as a surrogate of cancer presence. The salient finding in this study was that the model was able to predict the expected differences in EGFR concentration amongst the healthy tissue, U251, and A431. Kinetic model estimation of the ratio of EGFR concentration in U251 and A431 cell lines were in the ratio of 2:1, which correlates, with the expected ratio of EGFR concentration determined by flow cytometry which was close to 4:1. This technology not only promises to xii highlight tumor margins on a molecular level but can also be leveraged to analyze the molecular environment of the tumor to guide adjuvant precision therapies. Tracer kinetic modeling approaches were also applied to a guided precision therapy called Photodynamic therapy. Not only could the analysis of data provide parameter values for the tracer kinetics but an approach was also developed which with only a few initial data points could predict the time optimal for therapy in advance of the drug concentration maximum.

Show moreThis study evaluated the efficacy of three pulsed light systems (1.8, 3 and 100 Hz) for inactivation of Salmonella Montevideo on the surface of black pepper. The impact of frequency, treatment time and distance from the lamp on the rate of inactivation was studied. A reduction of 4.21 1og10 CFU/g was achieved with a 35 s treatment at 16.6-cm from lamp at 1.8 Hz. Similarly, reductions of 4.72 CFU/g and 4.70 CFU/g were obtained at 14.1-cm after 35 s treatment at 3 Hz and 100 Hz, respectively. Temperature measurement of packed and unpacked black pepper indicated that packaging material absorbed a small amount of energy. Measurement of surface and internal temperature suggested that temperature below the surface increased far less than surface temperature. For instance, temperature on the surface of the black pepper can go up to 200 °C as measured by the infrared camera within 30 to 40 s treatment. However, the temperature at 1 mm below the surface was up to 100 °C depending upon the distance from the lamp. The color of the black pepper did not change after pulsed light treatment (p>0.05). These results suggest that pulsed light can potentially be used to inactivate pathogens on black pepper surface without adversely affecting its quality.
