Linear systems identification algorithms for a minicomputer
Creators: name: Zuercher, Heinrich
Publisher: name: University of British Columbia
Year: 2010

description: Two methods for identifying multiple-input mutliple-output linear time-invariant discrete systems from input-output data are derived. The selector matrix principle of Gopinath is used and two special classes of selector matrices that lead to canonical system models are introduced. Very general input sequences can be applied. However, a few restrictions exist for the initial system state. The input matrix is identified columnwise. Both methods are considerably better than Gopinath's method in terms of storage requirements and numerical accuracy. Tests on a large computer are performed. One method is implemented on a minicomputer with good results.

description: Underground coal gasification is a complex physico-chemical process. UCG thermodynamic equilibrium model was established and validated, and the effects of the steam-to-oxygen ratio (RH2O/O2) and the equivalence ratio (ER) on the gasification temperature and the gaseous products were investigated. At low ER (0.08–0.14), coal is incompletely gasificated when the gasification temperature is less than the corresponding peak temperature. At high ER (0.16–0.30), coal is completely gasificated. With the increase of RH2O/O2, the gasification temperature decreases monotonically and finally tends to approach 850°C at RH2O/O2 = 4.5. H2 reaches high concentration at ER = 0.18–0.24 and RH2O/O2 = 1–3, but the change of CH4 concentration is just the opposite. CO concentration is high at RH2O/O2<1.5. In order to reach high the utilization effectiveness of oxygen, RH2O/O2 has the corresponding optimum value where the utilization effectiveness of oxygen reaches peak value at ER = 0.08–0.2.

description: We have performed real and momentum space spectroscopy of exciton polariton condensates in a GaAs-based microcavity under non-resonant excitation with an intensity stabilized laser. An effective trapping mechanism is revealed, which is due to the stimulated scattering gain inside the finite excitation spot combined with the short lifetime. We observe several quantized modes while the lowest state shows Heisenberg-limited real and momentum space distributions. The experimental findings are qualitatively reproduced by an open dissipative Gross-Pitaevskii equation model.

title: Bayesian Models for Repeated Measures Data Using Markov Chain Monte Carlo Methods
Creators: name: Li, Yuanzhi
Publisher: name: Utah State University
Year: 2016

description: Bayesian models for repeated measures data are fitted to three different data an analysis projects. Markov Chain Monte Carlo (MCMC) methodology is applied to each case with Gibbs sampling and / or an adaptive Metropolis-Hastings (MH ) algorithm used to simulate the posterior distribution of parameters. We implement a Bayesian model with different variance-covariance structures to an audit fee data set. Block structures and linear models for variances are used to examine the linear trend and different behaviors before and after regulatory change during year 2004-2005. We proposed a Bayesian hierarchical model with latent teacher effects, to determine whether teacher professional development (PD) utilizing cyber-enabled resources lead to meaningful student learning outcomes measured by 8th grade student end-of-year scores (CRT scores) for students with teachers who underwent PD. Bayesian variable selection methods are applied to select teacher learning instrument variables to predict teacher effects. We fit a Bayesian two-part model with the first-part a multivariate probit model and the second-p art a log-normal regression to a repeated measures health care data set to analyze the relationship between Body Mass Index (BMI) and health care expenditures and the correlation between the probability of expenditures and dollar amount spent given expenditures. Models were fitted to a training set and predictions were made on both the training set and the test set.
title: Comparing Sandwich Wall Panel Shear Connector Testing Methodologies
Creators: name: Syndergaard, Parker
Publisher: name: Utah State University
Year: 2018

description: Precast concrete sandwich wall panels (PCSWPs) have been used in the precast industry for decades due to their durability, rapid construction, and thermal efficiency. Shear connectors are used to connect the two wythes of concrete to allow composite action of the system. The use of glass fiber reinforced polymer (GFRP) connectors is a relatively recent breakthrough in PCSWP design. GFRP connectors allow full composite action to occur, while still maintaining the thermal efficiency of the system by not allowing thermal bridging to occur.
In order to design concrete sandwich panel systems to act compositely, the engineer must obtain design values from a connector manufacturer, often times making engineers uncomfortable. Shear connectors are typically proprietary and are required to first have design values often times varies by each company. This project aimed to compare existing testing methodologies in order to better inform engineers about design decisions.
This project used two methodologies of shear testing on five different types of composite action connectors. Testing was performed using single-shear and double-shear "push-off" tests. In order to gather enough statistical data to compare the testing methodologies, 22 single-shear and 48 double-shear small scale specimens were designed, fabricated, and loaded through failure at the Utah State University SMASH Lab. Testing was performed by applying loads perpendicular to the connectors and measuring the load and amount of deflection that occurred. Using the load-deflection relationships obtained, stiffness values were calculated and recorded for each test. A statistical analysis was performed based on the observed data.
This study concluded that the ultimate strength capacity and stiffness of connectors will change depending on the testing methodology used. Single-shear testing will generally provide less ultimate strength and less stiffness when compared to double-shear testing.

description: We studied in detail the structural relaxation and Jahn-Teller distortion in LaMnO3 (001) surface of the orthorhombic phase by means of classical atomistic simulation. It is found that MnO2-terminated surface is more energetically favorable than LaO-terminated surface by 0.34 eV. The standard deviation of Mn-O bond lengths of MnO6 octahedra and Jahn-Teller distortion oscillate in LaMnO3 (001) surface. Our simulated atomic displacements in the surface are compared with some ab initio studies.

title: Brownian Motion Applied to Partial Differential Equations
Creators: name: McKay, Steven M.
Publisher: name: Utah State University
Year: 1985

description: This work is a study of the relationship between Brownian motion and elementary, linear partial differential equations. In the text, I have shown that Brownian motion is a Markov process, and that Brownian motion itself, and certain Stochastic processes involving Brownian motion are also martingales. In particular, Dynkin's formula for Brownian motion was shown. Using Dynkin's formula and Brownian motion, I then constructed solutions for the classical Dirichlet problem and the heat equation, given by Δu=0 and ut= 1/2Δu+g, respectively. I have shown that the bounded solution is unique if Brownian motion will always exit the domain of the function once it has started at a point in the domain. The heat equation also has a unique bounded solution.

description: A nonlocal gravity model (2.1) was introduced and considered recently [49], and two exact cosmological solutions in flat space were presented. The first solution is related to some radiation effects generated by nonlocal dynamics on dark energy background, while the second one is a nonsingular time symmetric bounce. In the present paper we investigate other possible exact cosmological solutions and find some the new ones in nonflat space. Used nonlocal gravity dynamics can change background topology. To solve the corresponding eqations of motion, we first look for a solution of the eigenvalue problem $\Box (R -4Λ) = q\ (R - 4Λ) .$ We also discuss possible extension of this model with nonlocal operator symmetric under $\Box \longleftrightarrow \Box^{-1}$ and its connection with another interesting nonlocal gravity model.

description: Cryptocurrency wrench attacks are physical attacks targeting cryptocurrency users in the real world to illegally obtain cryptocurrencies. These attacks significantly undermine the efficacy of existing digital security norms when confronted with real-world threats. We present the first comprehensive study on wrench attacks. We propose a theoretical approach to defining wrench attacks per criminal law norms, and an interdisciplinary empirical approach to measure their incidence. Leveraging three data sources, we perform crime script analysis, detecting incidents globally across 10 interviews with victims and experts, 146 news articles, and 37 online forums. Our findings reveal diverse groups of attackers ranging from organized crime groups to friends and family, various modi operandi, and different forms of attacks varying from blackmail to murder. Despite existing since Bitcoin’s early days, these attacks are underreported due to revictimization fears. Additionally, unlike other cryptocurrency crimes, users with advanced security experience were not immune to them. We identify potential vulnerabilities in users’ behavior and encourage cryptocurrency holders to lean into digital as well as physical safety measures to protect themselves and their cryptocurrency. We offer actionable recommendations for the security community and regulators, highlighting the double-edged sword of Know Your Customer policies.

description: Synchronous satellites of Venus have long been thought unstable, but we use Poincare's surface of section technique to show that synchronous quasi-satellites orbiting just outside Venus' Hill sphere are quite stable, at least for centuries. Such synchrosats always remain within a few degrees of Venus' equator, and drift very slowly in longitude. These synchrosats could be useful for continuous monitoring of points on Venus' surface, such as active landforms or long-lived landers.

description: Purpose of Study. The ring-necked pheasant (Phasianus colchicus torquatus Gmelin) is well enough known to need no introduction. It is at present undoubtedly the most abundant and most important gallinaceous game bird in northern Utah. Its abundance and its occurrence in agricultural areas has stimulated much general interest. Yet, aside from two food habits studies, both conducted in Utah County, no intensive research has been made into its ecological relationships or its general life history in Utah.
In order to formulate sound management plans for the pheasant in Utah, the Utah Cooperative Wildlife Research Unit has felt the need for basic information regarding its mortality phases, movements, food habits, habitat preferences, interspecific relationships, and its effect on cultivated crops and the effect of farm practices upon its numbers and distributions.

description: The Carnegie Supernova Project (CSP) is a five-year survey being carried out at the Las Campanas Observatory to obtain high-quality light curves of ~100 low-redshift Type Ia supernovae in a well-defined photometric system. Here we present the first release of photometric data that contains the optical light curves of 35 Type Ia supernovae, and near-infrared light curves for a subset of 25 events. The data comprise 5559 optical (ugriBV) and 1043 near-infrared (YJHKs) data points in the natural system of the Swope telescope. Twenty-eight supernovae have pre-maximum data, and for 15 of these, the observations begin at least 5 days before B maximum. This is one of the most accurate datasets of low-redshift Type Ia supernovae published to date. When completed, the CSP dataset will constitute a fundamental reference for precise determinations of cosmological parameters, and serve as a rich resource for comparison with models of Type Ia supernovae.

title: Modular, Scalable Battery Systems with Integrated Cell Balancing and DC Bus Power Processing
Creators: name: Muneeb Ur Rehman, Muhammad
Publisher: name: Utah State University
Year: 2018

description: Traditional electric vehicle and stationary battery systems use series-connected battery packs that employ centralized battery management and power processing architecture. Though, these systems meet the basic safety and power requirements with a simple hard- ware structure, the approach results in a battery pack that is energy and power limited by weak cells throughout life and most importantly at end-of-life. The applications of battery systems can benefit significantly from modular, scalable battery systems capable of advanced cell balancing, efficient power processing, and cost gains via reuse beyond first-use application. The design of modular battery systems has unique requirements for the power electronics designer, including architecture, design, modeling and control of power processing converters, and battery balancing methods. This dissertation considers the requirements imposed by electric vehicle and stationary applications and presents design and control of modular battery systems to overcome challenges associated with conventional systems. The modular battery system uses cell or substring-level power converters to combine battery balancing and power processing functionality and opens the door to new opportunities for advanced cell balancing methods. This approach enables balancing control to act on cell-level information, reroute power around weaker cells in a string of cells to optimally deploy the stored energy, and achieve performance gains throughout the life of the battery pack. With this approach, the integrated balancing power converters can achieve system cost and efficiency gains by replacing or eliminating some of the conventional components inside battery systems such as passive balancing circuits and high-voltage, high-power converters. In addition, when coupled with life prognostic based cell balancing control, the modular system can extend the lifetime of a battery pack by up to 40%. The modular architecture design and control concepts developed in this dissertation can be applied to designs of large battery packs and improve battery pack performance, lifetime, size, and cost.

description: Strong laser emission from hydrogen cyanide (HCN) at 805 and 891 GHz has been discovered towards carbon-rich (C-rich) AGB stars, originating from the Coriolis-coupled system between two (1,1^{1e},0) and (0,4^0,0) vibrational states. However, other lines (at 894, 964, 968 and 1055 GHz) in this system remained unexplored due to observational challenges. Using SOFIA/4GREAT observations and Herschel/HIFI archival data, we analyzed the six HCN transitions in eight C-rich AGB stars. We report new HCN transitions show laser action at 964, 968, and 1055 GHz. The 805, 891, and 964 GHz lasers were detected in seven C-rich stars, the 968 GHz laser in six, and the 1055 GHz laser in five, while the 894 GHz line was not detected in any target. Among the detected lasers, the 891 GHz laser is always the strongest, and the 964 GHz laser, like a twin of the 891 GHz line, is the second strongest. Towards IRC+10216, all five HCN laser transitions were observed in six to eight epochs and exhibited significant variations in line profiles and intensities. The cross-ladder lines at 891 and 964 GHz exhibit similar variations, and their intensity changes do not follow the near-infrared light curve (i.e. non-periodic variations). In contrast, the variations of the rotational lines at 805, 968, and 1055 GHz appear to be quasi-periodic, with a phase lag of 0.1 - 0.2 relative to the near-infrared light curve. A comparative analysis indicates that these HCN lasers may be seen as analogues to vibrationally excited SiO and water masers in oxygen-rich stars. We suggest chemical pumping and radiative pumping could play an important role in the production of the cross-ladder HCN lasers, while the quasi-periodic behavior of the rotational HCN laser lines may be modulated by additional collisional and radiative pumping driven by periodic shocks and variations in infrared luminosity.

description: We present a thermodynamic theory of the Kovacs effect based on the idea that the configurational degrees of freedom of a glass-forming material are driven out of equilibrium with the heat bath by irreversible thermal contraction and expansion. We assume that the slowly varying configurational subsystem, i.e. the part of the system that is described by inherent structures, is characterized by an effective temperature, and contains a volume-related internal variable. We examine mechanisms by which irreversible dynamics of the fast, kinetic-vibrational degrees of freedom can cause the entropy and the effective temperature of the configurational subsystem to increase during sufficiently rapid changes in the bath temperature. We then use this theory to interpret the numerical simulations by Mossa and Sciortino (MS), who observe the Kovacs effect in more detail than is feasible in laboratory experiments. Our analysis highlights two mechanisms for the equilibration of internal variables. In one of these, an internal variable first relaxes toward a state of quasi-equilibrium determined by the effective temperature, and then approaches true thermodynamic equilibrium as the effective temperature slowly relaxes toward the bath temperature. In the other mechanism, an internal variable directly equilibrates with the bath temperature on intermediate timescales, without equilibrating with the effective temperature at any stage. Both mechanisms appear to be essential for understanding the MS results.

description: The vibrational spectroscopy of semiconductor nanostructures can provide important information on their structure. In this work, experimental Raman and infrared spectra are compared with vibrational spectra of CdSe/CdS core/shell nanoplatelets calculated from first principles using the density functional theory. The calculations confirm the two-mode behavior of phonon spectra of nanostructures. An analysis of the experimental spectra reveals the absence of modes with a high amplitude of vibrations of surface atoms, which indicates their strong damping. Taking into account the difference in the damping of different modes and their calculated intensities, all bands in the spectra are unambiguously identified. It is found that the frequencies of longitudinal optical modes in heterostructures are close to the frequencies of LO phonons in bulk strained constituents, whereas the frequencies of transverse modes can differ significantly from those of the corresponding TO phonons. It is shown that an anomalous thickness dependence of CdS TO mode is due to a noticeable surface relaxation of the outer Cd layer in the nanostructure.

description: This study examined the efficacy of a brief culturally and instructionally modified cognitive behavioral therapy program for five anxious Latino/a youths ages 8-11 years in an elementary school setting. Each student exhibited anxiety in a classroom setting as reported by their teachers and parents or guardians. A noncurrent multiple baseline design was implemented using A-B replications to assess the effects of baseline and treatment on daily self-report student distress ratings as well as daily teacher rated distress, academic engagement, and work completion. All participants completed the Revised Children’s Manifest Anxiety Scale-2 pre- and post-treatment as well as a Children’s Intervention Rating Profile post-treatment. The participants received a total of five sessions twice a week to teach skills. With the modified program, it was found that four of the five students benefited from the intervention on academic performance or engagement and three of the five also benefited on emotional regulation ratings. Additionally, all five students perceived the intervention as acceptable. Suggestions for future research include further assessment of student acculturation and acculturative stress, including more phone call check-ins and/or visits with parents, further assessment of the degree of teacher support of learned skills, and teacher acceptability of the intervention.

title: Does Neighborhood Context Matter? A Multilevel Analysis of Neighborhood Disadvantage and Sleep Health
Creators: name: Graham, Carlyn E.
Publisher: name: Utah State University
Year: 2018

description: Childhood is one of the most important stages for physical and cognitive growth during the life course. For young children, sleep is one of the major contributors to healthy development; poor sleep quality and short sleep duration can detrimentally affect developmental progress. In addition to physiological contributors to poor sleep, social factors may affect young children’s sleep. Prior findings suggest that demographic and socioeconomic characteristics, such as race and parent’s educational attainment, may contribute to sleep health for children. Furthermore, limited prior research suggests that neighborhood attributes may affect sleep for both children and adults alike. To my knowledge, no study exists that examines neighborhood effects and sleep for children under the age of six. Therefore, my investigation examines the effect of neighborhood disadvantage on the bedtimes of kindergarten-aged children, a proxy for sleep health.
In order to examine the effects of neighborhood disadvantage on sleep, this study utilizes multilevel statistical methods to determine the influence of both individual- and neighborhood-level characteristics. The results from these analyses indicate that while individual-level demographic and socioeconomic characteristics contribute explain more variance in bedtimes than neighborhood-level attributes, neighborhoods significantly affect bedtimes—especially racial composition and overall levels of educational attainment. These findings suggest the need for further research on the effects of neighborhoods on sleep and ultimately health outcomes.

description: We present the results of a multisite photometric campaign on the pulsating sdB star Balloon 090100001. The star is one of the two known hybrid hot subdwarfs with both long- and short-period oscillations. The campaign involved eight telescopes with three obtaining UBVR data, four B-band data, and one Stromgren uvby photometry. The campaign covered 48 nights, providing a temporal resolution of 0.36microHz with a detection threshold of about 0.2mmag in B-filter data. Balloon 090100001 has the richest pulsation spectrum of any known pulsating subdwarf B star and our analysis detected 114 frequencies including 97 independent and 17 combination ones. The strongest mode (f_1) in the 2.8mHz region is most likely radial while the remaining ones in this region form two nearly symmetric multiplets: a triplet and quintuplet, attributed to rotationally split \ell=1 and 2 modes, respectively. We find clear increases of splitting in both multiplets between the 2004 and 2005 observing campaigns, amounting to 15% on average. The observed splittings imply that the rotational rate in Bal09 depends on stellar latitude and is the fastest on the equator. We use a small grid of models to constrain the main mode (f_1), which most likely represents the radial fundamental pulsation. The groups of p-mode frequencies appear to lie in the vicinity of consecutive radial overtones, up to the third one. Despite the large number of g-mode frequencies observed, we failed to identify them, most likely because of the disruption of asymptotic behaviour by mode trapping. The observed frequencies were not, however, fully exploited in terms of seismic analysis which should be done in the future with a larger grid of reliable evolutionary models of hot subdwarfs.

description: Frequency-domain representations are crucial for the design and performance evaluation of controllers in multirate systems, specifically to address intersample performance. The aim of this paper is to develop an effective frequency-domain system identification technique for closed-loop multirate systems using solely slow-rate output measurements. By indirect identification of multivariable time-invariant representations through lifting, in combination with local modeling techniques, the multirate system is effectively identified. The developed method is capable of accurate identification of closed-loop multirate systems within a single identification experiment, using fast-rate excitation and inputs, and slow-rate outputs. Finally, the developed framework is validated using a benchmark problem consisting of a multivariable dual-stage actuator from a hard disk drive, demonstrating its applicability and accuracy.
Prototype of a continental shelf tide gauge
Creators: name: Galloway, James Lewis
Publisher: name: University of British Columbia
Year: 2010

description: Specifications and design for a self-contained tide gauge are presented. The gauge is suitable for immersion to a depth of 1000 meters for a period of one year with a five minute sample rate. A Vibrotron absolute pressure transducer is the sensing element with pressure measured to an equivalent water height of one millimeter. Instrumental and oceanic filtering of wind waves and tradeoffs in sampling techniques are investigated. Storage and reduction of data is arranged to provide useful statistical information on instrument performance. Transducer calibration data analysis indicates that careful choice of calibration polynomial can significantly improve accuracy of tidal data. In situ tests and analysis of results indicate adequate instrument performance, but high precision comparisions between sea bottom pressure and measured water height are of limited value in the test region due to variations in mean water density. Spectra results reveal the presence of seiches distinctive to the test region. Comparisions between shore-based staff readings and offshore pressure data indicate the possible presence of unusual dynamic water density structure at the test site.

description: During and after missions on the International Space Station, some astronauts experience ophthalmic changes, including choroidal folds, optic disc edema, cotton-wool spots, globe flattening, and refraction changes. Astronauts with ophthalmic issues had significantly higher plasma concentrations of metabolites that are associated with the 1-carbon metabolic pathway than those without ophthalmic issues. We hypothesized that genetic differences might explain the metabolite differences. Indeed, genetics and B vitamin status were significant predictors of ophthalmic issues. We now have developed a hypothesis regarding the mechanisms that link 1-carbon pathway genetics and the condition that we suggest calling, “astronaut ophthalmic syndrome.” We maintain that this condition is genetically predisposed and is associated with endothelial dysfunction that is induced by oxidative stress. Subsequent edema can hinder cerebrospinal fluid efflux and can lead to locally increased pressures in the subarachnoid space within the orbit, which impinges on the optic nerve and/or eye in affected individuals. Confirming this hypothesis will help characterize the genetics of 1-carbon pathway metabolism, homocysteine, oxidative stress, endothelial dysfunction, and cardiovascular and potentially other diseases.

description: A cover of normal varieties is exceptional over a finite field if the map on points over infinitely many extensions of the field is one-one. A cover over a number field is exceptional if it is exceptional over infinitely many residue class fields. The first result: The category of exceptional covers of a normal variety, Z, over a finite field, F_q, has fiber products, and therefore a natural Galois group (with permutation representation) limit. This has many applications to considering Poincare series attached to diophantine questions. The paper follows three lines: * The historical role of the Galois Theoretic property of exceptionality, first considered by Davenport and Lewis. * How the tower structure on the category of exceptional covers of a pair (Z,F_q) allows forming subtowers that separate known results from unknown territory. * The use of Serre's OIT, especially the GL_2 case, to consider cryptology periods and functional composition aspects of exceptionality.

«Quel misterioso fondo del nostro essere»: una glossa a Die Geburt der Tragödie, di Nietzsche
Creators: name: Sola, Giancarla

Year: 2013

description: The article is focused on Nietzsche’s work entitled Die Geburt der Trägodie and his aim is to interpret the relationship between the problem of “Ursprüngli- chkeit” and the concept of “Bildung”. In other words, the attention is directed at the formation of the human being and his original dimension.More specificly, the pedagogical analyse is concentrated on the attack that Nietzsche addresses to the modern individual, which nowadays is only the appear- ance of himself.

title: Distribution of Particle Image Velocimetry (PIV) Errors in a Planar Jet
Creators: name: Howell, Jaron A.
Publisher: name: Utah State University

description: Particle Image Velocimetry (PIV) is an optical fluid measurement technique used to obtain velocity measurements. Two PIV systems were used to capture data simultaneously and measurement error for the MS PIV system is calculated. An investigation of error distribution is performed to determine when uncertainty estimations fail for the CS PIV-UQ method. Investigation of when results from multi pass PIV processing are achieve were performed so that reliable uncertainty estimations are produced with the CS method. An investigation was also performed which determined that error distributions in PIV systems are correlated with flow shear and particle seeding density. Correlation of random errors in space was also performed at the jet core and shear regions of the flow.
It was found that in flow regions with large shear that error distributions were non-Gaussian. It was also found in regions of large shear that CS uncertainty results did not match the error. For multi-pass PIV processing with 50% and 75% IW overlap it was found that 4 and 6 passes should be used, respectively, in order for CS uncertainty estimations to be reliable. It was also found that the correlation of random errors in space is much larger in shear regions of the jet flow than in the jet core.
