Incorporating Priors For Medical Image Segmentation Using A Genetic Algorithm, Payel Ghosh, Melanie Mitchell, James A. Tanyi, Arthur Y. Hung

Computer Science Faculty Publications and Presentations

Medical image segmentation is typically performed manually by a physician to delineate gross tumor volumes for treatment planning and diagnosis. Manual segmentation is performed by medical experts using prior knowledge of organ shapes and locations but is prone to reader subjectivity and inconsistency. Automating the process is challenging due to poor tissue contrast and ill-defined organ/tissue boundaries in medical images. This paper presents a genetic algorithm for combining representations of learned information such as known shapes, regional properties and relative position of objects into a single framework to perform automated three-dimensional segmentation. The algorithm has been tested for prostate segmentation …

Detecting Faults In Turbine Generators, Wei Qiao, Xiang Gong

Department of Electrical and Computer Engineering: Faculty Publications

Turbine generator faults can be detected by receiving a current signal from the turbine generator, and synchronously sampling the current signal to obtain a set of current signal samples that are evenly spaced in the phase domain, in which phase differences between adjacent current signal samples in the set of current signal samples are substantially the same. The process includes generating a frequency spectrum of the current signal samples, identifying one or more excitations in the frequency spectrum, and detecting a fault in the turbine generator based on the one or more excitations in the frequency spectrum.

Cracking The Code: Driverless Cars Vs. Hackers | College Of Engineering, Usu College Of Engineering

College of Engineering News

Feb. 3, 2016 – Electrical and computer engineering researchers at USU are finding ways to defeat the safety and security measures in place to keep driverless cars rolling safely down the road.

And while it’s a complex exercise, the group says it hasn’t found a single layer of security they haven’t been able to defeat. It’s all part of a four-year study led by Assistant Professor Dr. Ryan Gerdes who was recently awarded a major grant from the National Science Foundation to study the security of autonomous vehicles and incorporate what he calls ‘adversarial thinking’ into the design process.

Graphene Oxide Quantum Dots Covalently Functionalized Pvdf Membrane With Significantly-Enhanced Bactericidal And Antibiofouling Performances, Zhiping Zeng, Dingshan Yu, Ziming He, Jing Liu, Fang-Xing Xiao, Yan Zhang, Rong Wang, Dibakar Bhattacharyya, Timothy Thatt Yang Tan

Chemical and Materials Engineering Faculty Publications

Covalent bonding of graphene oxide quantum dots (GOQDs) onto amino modified polyvinylidene fluoride (PVDF) membrane has generated a new type of nano-carbon functionalized membrane with significantly enhanced antibacterial and antibiofouling properties. A continuous filtration test using E. coli containing feedwater shows that the relative flux drop over GOQDs modified PVDF is 23%, which is significantly lower than those over pristine PVDF (86%) and GO-sheet modified PVDF (62%) after 10 h of filtration. The presence of GOQD coating layer effectively inactivates E. coli and S. aureus cells, and prevents the biofilm formation on the membrane surface, producing excellent antimicrobial activity and …

Numerical Modeling Of Nonlinear Mode Interaction In Semiconductor Lasers And Amplifiers To Generate Slow/Fast Light, Hemashilpa Kalagara

Electrical and Computer Engineering ETDs

The nonlinear interaction (NLI) between modes in a semiconductor laser or amplifier is one of the techniques to obtain slow light (ng >> 1), fast light (-1 < ng < 1), phase conjugated reflection (also known as backward light (ng < 0)) and supercontinuum emission (also known as critically anomalous dispersion (ng = 0)), where ng is the group index. In the nonlinear interaction (NLI) mechanism, the interaction between a driving wave (mode) which is of sufficiently high intensity, and a probe wave (mode) results in modification of complex permittivity of the probe wave, if the frequency detuning between the two waves falls into the spectral range of parametric interaction. Consequently, in the vicinity of a strong driving wave (mode), the optical parameters such as the phase index, group index, linewidth, and the gain of a neighboring probe (weak) wave are strongly perturbed. The unusual perturbation of group index leads to slow light, fast light and backward propagating light depending on the frequency detuning between the two waves. Fast light can have important applications in interferometry, to make very sensitive interferometric sensors for detection of nano displacement, ultra-low vibration, rotation rate and even very weak gravitational waves. The slope sensitivity of an active integrated ring laser gyro (RLG) is directly proportional to the size of the ring and inversely proportional to the group index of the medium filling the cavity. By reducing ng in the nonlinear regime of laser operation, slope sensitivity can be improved by manifolds without having to increase the size of the gyro, which will lead to monolithic integration. In this dissertation work, the numerical modeling and simulation of NLI in semiconductor ridge waveguide (RWG) lasers is performed and perturbations of phase index, group index, gain, linewidth are calculated. The modeling is based on theory of nonlinear interaction of waves' developed for plane waves and is applied to RWG lasers. The RWG laser structures are based on GaN/InGaN, GaAs/AlGaAs, InGaAs/GaAs/AlGaAs, InGaAsP/InP material systems, to cover the most important spectral range of semiconductor lasers starting from λ = 0.4 μm to λ = 1.55 μm, respectively. The photonic design software RSoft's FemSIM that uses finite element method is used for design and modeling of NLI in RWG and calculation of effective phase index. The induced dispersion and effective group index ng are then calculated by differentiation of the effective phase index of guided probe wave over the optical frequency. The calculations indicate that the magnitude of NLI depends on the driving wave intensity, frequency detuning between driving and probe waves, lifetime of carriers in the laser system, optical confinement factor, driving wave wavelength and linewidth broadening factor of the laser structure. An important result of this work is observation of frequency points where ng passes zero line, known as the points of critically anomalous dispersion (CAD). In the spectral vicinity of CAD points, superluminal group velocity is observed, which can be used for improving the sensitivity of ring laser gyros and other interferometric sensors. In this dissertation, we established possibility of superluminal behavior (-1 < ng < 1) through NLI in all of the above mentioned RWG laser structures, and obtained the conditions necessary to observe this behavior. Also, the CAD frequencies are plotted by varying the driving wave intensities, where the data form a closed loop. The closing of the loop is due to suppression of NLI with an increase in driving wave intensity; at high intensities, the stimulated recombination rate increases, leading to an increase in overall relaxation rate, which in turn decreases the NLI. The CAD loops are calculated for all the RWG lasers mentioned above. The CAD loops provide information on lower and upper threshold intensity of the driving wave, and on frequency detuning between the driving and probe waves for observation of superluminal group velocity. Another important result is that the perturbed linewidth increases infinitely at the CAD point, leading to supercontinuum emission or white light, which can be exploited for very broadband laser emission applications. We also fitted our numerically calculated perturbed delay and advance due to NLI with the experimental data of perturbed delay and advance of an optical pulse in a semiconductor optical amplifier based on InGaAsP/InP, and identified the CAD point for the very first time.'

Equilibrium Testing Of Rat Tail Tendon: An Analysis Of The Viscoelastic Properties Of Collagen Under Different Strain Points, Joshua C. Witt

Graduate Theses - Biology & Biomedical Engineering

Instantaneous tensile testing and stress-relaxation testing are forms of mechanical testing used to determine the elastic and viscoelastic properties of biological tissue. Equilibrium testing is a form of testing that combines both of these testing approaches at different strain points to determine the elastic properties of a material and also assess their viscoelastic properties in the same test. This testing method is commonly used on highly viscoelastic materials such as cartilage but has never been fully described in dense collagenous materials such as tendon or ligament. This analysis utilizes different strain points selected to capture the classic non-linear behavior of …

Multiclass Object Detection With Single Query In Hyperspectral Imagery Using Class-Associative Spectral Fringe-Adjusted Joint Transform Correlation, Paheding Sidike, Vijayan K. Asari, Mohammad S. Alam

Electrical and Computer Engineering Faculty Publications

We present a deterministic object detection algorithm capable of detecting multiclass objects in hyperspectral imagery (HSI) without any training or preprocessing. The proposed method, which is named class-associative spectral fringe-adjusted joint transform correlation (CSFJTC), is based on joint transform correlation (JTC) between object and nonobject spectral signatures to search for a similar match, which only requires one query (training-free) from the object's spectral signature. Our method utilizes class-associative filtering, modified Fourier plane image subtraction, and fringe-adjusted JTC techniques in spectral correlation domain to perform the object detection task.

The output of CSFJTC yields a pair of sharp correlation peaks for …

A Five-Year Performance Review Of Field-Scale, Slow-Release Permanganate Candles With Recommendations For Second-Generation Improvements, Mark Christenson, Ann Kambhu, James Reece, Steve D. Comfort, Laurie Brunner

Nebraska Water Center: Faculty Publications

In 2009, we identified a TCE plume at an abandoned landfill that was located in a low permeable siltyclay aquifer. To treat the TCE, we manufactured slow-release potassium permanganate cylinders (oxidant candles) that had diameters of either 5.1 or 7.6 cm and were 91.4 cm long. In 2010, we compared two methods of candle installation by inserting equal masses of the oxidant candles (7.6-cm vs 5.1-cm dia). The 5.1-cm dia candles were inserted with direct-push rods while the 7.6-cm candles were housed in screens and lowered into 10 permanent wells. Since installation, the 7.6-cm oxidant candles have been refurbished approximately …

The Effect Of Assembly Technique On Weak Polyelectrolyte Multilayer Film Morphology And Humidity Swelling/Deswelling Behavior, Ziyang Yin

Graduate Theses - Chemical Engineering

The goal of this research is to investigate the film morphology and humidity swelling/deswelling behavior of polyelectrolyte multilayers (PEMs) that are constructed from poly(allylamine hydrochloride) (PAH) and poly(acrylic acid) (PAA) by two assembly techniques: automated dipping layer-by-layer (LbL) and spin-assisted (SA) LbL. Two sets of pH polyelectrolyte solution conditions were tested: (PAH7.5/PAA3.5) and (PAH7.0/PAA7.0). It was found that when the films were constructed with the same number of bilayers (=20 bilayers), SA-LbL (PAH7.5/PAA3.5) has a greater thickness than (PAH7.0/PAA7.0). (PAH7.5/PAA3.5) thin films constructed by automated dipping LbL did not result in a uniform film morphology, making thickness comparisons between techniques …

Histogram Of Oriented Phase And Gradient (Hopg) Descriptor For Improved Pedestrian Detection, Hussin Ragb, Vijayan K. Asari

Electrical and Computer Engineering Faculty Publications

This paper presents a new pedestrian detection descriptor named Histogram of Oriented Phase and Gradient (HOPG) based on a combination of the Histogram of Oriented Phase (HOP) features and the Histogram of Oriented Gradient features (HOG).

The proposed descriptor extracts the image information using both the gradient and phase congruency concepts. Although the HOG based method has been widely used in the human detection systems, it lacks to deal effectively with the images impacted by the illumination variations and cluttered background. By fusing HOP and HOG features, more structural information can be identified and localized in order to obtain more …

A Real-Time Information Based Demand-Side Management System In Smart Grid, Feng Ye, Yi Qian, Rose Qingyang Hu

Electrical and Computer Engineering Faculty Publications

In this paper, we study a real-time information based demand-side management (DSM) system with advanced communication networks in smart grid. DSM can smooth peak-to-average ratio (PAR) of power usage in the grid, which in turn reduces the waste of fuel and the emission of greenhouse gas. We first target to minimize PAR with a centralized scheme. To motivate power suppliers, we further propose another centralized scheme targeting minimum power generation cost. However, customers may not be motivated by a centralized scheme since such a scheme requires total control and privacy from them. A centralized scheme also requires too much real-time …
