Geology of the Crawford Bay map-area.
Creators: name: Livingstone, Kent Wayne
Publisher: name: University of British Columbia
Year: 2011

description: The Crawford Bay map-area is fifty square miles on the east side of Kootenay Lake, southeastern British Columbia, and is part of a regional structural belt, the Kootenay Arc, (Hedley, 1955). It is underlain by strongly deformed and metamorphosed strata of Late Proterozoic to possible Middle Paleozoic age. Sill-like bodies and boudins of metamorphosed amphibolite, and subordinate post-kinematic granitic intrusions and basic dykes of probable Mesozoic age are present in the west part of the map-area. Lithologic succession was determined by use of primary structures in the east part of the map-area and by lithologic correlation in the more highly metamorphosed western part. Horsethief Creek Group, Lower Hamill Group, Upper Hamill Group, Mohican and Badshot Formations, and Lardeau Group comprise an apparent conformable succession. Rock-unit nomenclature is the same as used for similar strata in the Kootenay Arc of the Lardeau and Salmo areas. However, fault-bound Upper Hamill is composed of strata which do not have defined lithologic equivalents outside the map-area and more detailed study of this part of the succession is suggested. The sequence is unfossilifereous and and age of the strata is based on correlation of Badshot Formation with Badshot outside the map-area that has yielded Archeocyathids of late Lower Cambrian age. Three phases of deformation, of variable intensity, are recognized within the map-area. Phase one folds are the earliest tectonic event and delineate the main structural trend. Three major folds, outlined by stratigraphic mapping, the Plaid Lake syncline, the Washout Creek syncline, and the Crawford Bay synform, are believed to be phase one structures. Early phase folds are isoclinal "similar" with axial planes parallel to gross lithologic layering. Fold axes and related penetrative mineral lineation plunge up to 20° northward except where locally deformed by subsequent structures. Only small scale phase two folds are recognized. These are asymmetric "similar" folds with southeast trending axial planes which dip moderately to the southwest, and westward plunging fold axes. Major faults may have formed during either phase of deformation. Kinks and related quartz veins formed during phase three deformation. Folding of bedding by phase three kinks is considered to be flexural-slip. Regional metamorphism is synkinematic with phase one and two deformation. Culmination of metamorphism appears to be post-faulting and post-phase two deformation. Phase three deformation is post-metamorphic. Chlorite, biotite, garnet, diopside, and sillimanite zones delineate an increasing metamorphic gradient from east to west. Distribution coefficients, KD= Mg/Fe garnet / Mg/Fe biotite, of Mg and Fe in coexisting garnet and biotite pairs in Mohican Formation, are larger with increasing metamorphic grade from the east limb to the west limb of the Crawford Bay synform.
title: Aerating Butterfly Valves to Suppress Cavitation
Creators: name: Davis, R. Ted
Publisher: name: Utah State University
Year: 1986

description: Proper aeration of cavitating hydraulic equipment can greatly reduce cavitation intensity, noise, and damage. This thesis quantifies the benefit, in terms of damage and noise, from aerating six inch butterfly valve. The incipient damage level of cavitation was obtained for both aerated and non -ae ra ted conditions. The level is defined as one pit per square inch of a soft aluminum test specimen per one minute of operation. A description of the cavitation pits that occurred plus where they appeared is presented. A graph showing the aerated and non-aerated limits of incipient damage is given along with a table showing the percent reduct ion of damage from aeration. A graph and table are also given depicting the reduction in noise. The proper location of aeration ports to allow natural aeration is outlined .

description: A flavor-nonuniversal chiral color model is introduced. It is used for comparison to the recent data on $\bar{p} p \to \bar{t} t$. We concluded that the data are consistent with interpretation as an axigluon exchange within 1$σ$ and a unique rise and fall behavior is predicated with regard to the asymmetry $A^t_{FB}$ as a function of $t \bar{t}$ invariant mass, which can distinguish our model from others before one discovers the axigluon resonance. Further aspects of the model are discussed.

description: We present a data mining technique for the analysis of multichannel oscillatory timeseries data and show an application using poloidal arrays of magnetic sensors installed in the H-1 heliac. The procedure is highly automated, and scales well to large datasets. The timeseries data is split into short time segments to provide time resolution, and each segment is represented by a singular value decomposition (SVD). By comparing power spectra of the temporal singular vectors, singular values are grouped into subsets which define fluctuation structures. Thresholds for the normalised energy of the fluctuation structure and the normalised entropy of the SVD are used to filter the dataset. We assume that distinct classes of fluctuations are localised in the space of phase differences between each pair of nearest neighbour channels. An expectation maximisation clustering algorithm is used to locate the distinct classes of fluctuations, and a cluster tree mapping is used to visualise the results.

description: In this article we develop an effective theory of pulse propagation in a nonlinear and disordered medium. The theory is formulated in terms of a nonlinear diffusion equation. Despite its apparent simplicity this equation describes novel phenomena which we refer to as "locked explosion" and "diffusive" collapse. In this sense the equation can serve as a paradigmatic model, that can be applied to such distinct physical systems as laser beams propagating in disordered photonic crystals or Bose-Einstein condensates expanding in a disordered environment.

description: The effects of spin-orbit coupling on the two-electron spectra in lateral coupled quantum dots are investigated analytically and numerically. It is demonstrated that in the absence of magnetic field the exchange interaction is practically unaffected by spin-orbit coupling, for any interdot coupling, boosting prospects for spin-based quantum computing. The anisotropic exchange appears at finite magnetic fields. A numerically accurate effective spin Hamiltonian for modeling spin-orbit-induced two-electron spin dynamics in the presence of magnetic field is proposed.

title: A Sociocultural Analysis of Latino High School Students' Funds of Knowledge and Implications for Culturally Responsive Engineering Education
Creators: name: Mejia, Joel Alejandro
Publisher: name: Utah State University
Year: 2014

description: The purpose of this study was to investigate the funds of knowledge of Latino and Latina high school adolescents, and how they used their funds of knowledge to solve engineering design problems in their communities. This study was based on the assumption that creating a bridge between different formal resources (e.g., engineering design processes) and informal resources (e.g., funds of knowledge) is an important step toward encouraging Latino and Latina high school adolescents to enter and remain in the field of engineering. The intent of this study was to generate a framework of funds of knowledge that teachers can draw from in order to create culturally responsive high school engineering instruction that connects adolescents’ out-of-school practices to the formal practices of engineering.
An ethnographic approach was used to investigate the funds of knowledge of fourteen Latino and Latina high school adolescents. The participants were selected from a rural community located in the Western United States. They were divided into four different groups and each group selected a problem in their community that was of interest to them. Each group met twice per month and every student was interviewed every month individually. For this study, data sources included participant responses to individual interviews, observations of group discussions, retrospective and concurrent protocols, and participant-generated products.
A constant comparative analysis showed that the participants possessed an understanding of societal, environmental, technical, and other engineering-related practices, dispositions, and habits of mind, which helped them to engage in engineering design in a holistic way. The study suggested that Latino and Latina adolescents, although profoundly underrepresented in engineering, bring a wealth of knowledge and experiences that are relevant to engineering design thinking and practice.

description: We study the doubly virtual Compton scattering off a spinless target $γ^*P\toγ^*P'$ within the Anti-de Sitter(AdS)/QCD formalism. We find that the general structure allowed by the Lorentz invariance and gauge invariance of the Compton amplitude is not easily reproduced with the standard recipes of the AdS/QCD correspondence. In the soft-photon regime, where the semi-classical approximation is supposed to apply best, we show that the measurements of the electric and magnetic polarizabilities of a target like the charged pion in real Compton scattering, can already serve as stringent tests.

Contact relationships of Mount Carlyle Stock Slocan, British Columbia
Creators: name: Childs, John Frazer
Publisher: name: University of British Columbia
Year: 2011

description: The deformed Triassic Slocan Group sedimentary rocks consisting of argillite, limestone, and quartzite, have been regionally metamorphosed, folded, and intruded and thermally metamorphosed by Nelson Plutonic Rocks (Jurassic). Mt. Carlyle stock, a compositionally zoned body 21 square miles in aerial extent, was emplaced by forceful intrusion and passive assimilation as discerned from the contact effects on the Slocan Group metasediments. The margin of the stock is enveloped in a contact metamorphic aureole with biotite, andalusite, garnet and stauro-lite, cordierite, and sillimanite developed in approximate increasing order of proximity to the stock margin. Petrographic and structural evidence in a septum of Slocan Group metasediments between Mt. Carlyle stock and the Nelson Batholith to the south suggests that the stock postdates the batholith. Experimental data pertinent to the metamorphic mineral assemblages in the contact aureole of Mt. Carlyle stock indicate that temperatures up to approximately 650° c and pressures between 2½ and 7Kb. prevailed during contact metaaorphism. The metamorphism in the contact regions of the stock is characteristic of facies series intermediate between contact and regional conditions.

description: In the context of minimal seesaw framework, we study the implications of Dirac and Majorana mass matrices in which two rigid properties coexist, namely, equalities among mass matrix elements and texture zeros. In the first part of the study, we discuss general possibilities of the Dirac and Majorana mass matrices for neutrinos with such hybrid structures. We then classify the mass matrices into realistic textures which are compatible with global neutrino oscillation data and unrealistic ones which do not comply with the data. Among the large number of general possibilities, we find that only 6 patterns are consistent with the observations at the level of the most minimal number of free parameters. These solutions have only 2 adjustable parameters, so that all the mixing angles can be described in terms of the two mass differences or pure numbers. We analyze these textures in detail and discuss their impacts for future neutrino experiments and for leptogenesis.

title: Impact of Organic Matter Composition from Urban Streams and Storm Water on Oxygen Consumption in the Jordan River
Creators: name: Richardson, Jacob Matt
Publisher: name: Utah State University
Year: 2014

description: Coarse particulate organic matter (CPOM) is an essential part of the food chain in aquatic ecosystems because it represents a readily available carbon and energy source. The process by which it decomposes in rivers has been well studied and documented. However, the rate and extent of biodegradability of various CPOM components (i.e., twigs, leaves, grass, etc.) in storm drains is not well understood. The Jordan River TMDL study identified storm water generated CPOM as a likely cause of low dissolved oxygen levels in the lower Jordan River, but recent investigations have suggested that dissolved organic matter generated from this CPOM in storm drains and culverts entering into the Jordan River, rather than the CPOM itself, is the main driver of oxygen impairment. The degradability of CPOM components transported and stored in the storm drain system was studied to understand its relative impact on dissolved oxygen and nutrient status in the Jordan River. Results indicate the generation of highly degradable organic material is a function of the starting CPOM, and oxygen consumption is associated with the dissolved portion of organic material leached from CPOM in water. Leaves and grass produced the highest levels of all parameters studied. Between 93% to 95% of total oxygen demand is generated within the first 1 to 3 hours of the 24 hour test. Chemical oxygen demand and dissolved organic carbon proved to be the best indicator of biochemical oxygen demand. By using the results of the leaching study an estimate of water quality indicator levels in the Jordan River was made, and was compared to levels in samples collected from the Jordan River. The estimate proved accurate for dissolved organic carbon but not for total or volatile suspended solids. Results of this study were used to discuss possible solutions to reduce oxygen demand in the Jordan River.

description: The clustering amplitude of galaxies depends on their intrinsic luminosity. We compare the properties of publicly available galaxy formation models with clustering measurements from the two-degree field galaxy redshift survey. The model predictions show the same qualitative behaviour as the data but fail to match the observations at the level of accuracy at which current measurements can be made. We demonstrate that this is due to the model producing too many satellite galaxies in massive haloes. We implement simple models to describe two new processes, satellite-satellite mergers and the tidal dissolution of satellites to investigate their impact on the predicted clustering. We find that both processes need to be included in order to produce a model which matches the observations.

description: Progressive queries (PQ) are a new type of query emerging from numerous contemporary database applications, including e-commerce, social network, business intelligence, and decision support. Such a PQ is formulated in several steps via a set of inter-related step-queries (SQ). How to optimize such PQs represents a new challenge in the development of a database management system. In our previous work, we introduced a materialized-view based technique to process a special type of PQ, called monotonic linear PQs. In this paper, we present a new materialized-view based technique to efficiently process generic PQs. This technique allows an SQ in a given PQ to utilize the results of previous SQs not only from the same PQ but also from other in-process and completed PQs. Due to the storage constraint, it is impossible to retain the results of all the SQs of a completed PQ. Hence, a crucial issue is how to select popular SQs from completed PQs to keep their results as materialized views for optimizing future PQs. To tackle this issue, we introduce a multiple query dependency graph (MQDG) to capture the data source dependency relationships among SQs from multiple PQs. We then present a model to estimate the benefit of an SQ in the MQDG and discuss a procedure to choose critical SQs in the MQDG for materializing their results. The strategies for constructing the MQDG and maintaining the set of materialized views are also suggested. Experimental results demonstrate that our technique is quite promising in efficiently processing PQs.
title: Effects of Processing and Packaging Modifications on the Quality and Shelf Life in Meats
Creators: name: Khan, Abdulla
Publisher: name: Utah State University
Year: 2014

description: Shelf life of meat and meat products depends on the quality of meat and packaging stability. Meat color change, lipid oxidation, pH, and microbial contamination are the main causes that affect the nutritional, sensory, and physical characteristics by forming toxic compounds, off flavors, off odors, and undesirable color. The first objective of this study was to examine the effect of newly developed CO2 generating absorbent pads on beef, tuna and chicken meats. The second objective was to compare the effect of Type I (radical quenching) antioxidants eugenol and rosmarinic acid (RA) to that of Type II (metal chelating) antioxidants milk mineral (MM), phytate, and sodium tri-polyphosphate (STPP) in raw ground chicken patties. In the first study samples of beef semitendinosus muscle, boneless and skinless chicken breast, and yellowfin tuna loins were chosen and packaged with four different pad types. Red meats and chicken exhibited trends as would normally be expected during storage. Specifically, color became less appealing (beef and tuna color changed from red to brown, and chicken changed from yellow–pink to grey); pH increased, microbial counts increased, and lipid oxidation (rancidity) increased. Lightness (L*) values for chicken were within 46 – 54, for tuna L* value range was 21-26. Redness/greenness (a*) is an indicator of freshness in red meats, and for beef steaks an average value of 12.32 was noted on day 8, indicative of fresh red color. Recorded average lipid oxidation (TBA values in mg/kg of meat) for chicken (< 0.19 mg/kg) and tuna were low (< 0.16 mg/kg) and for beef (1.06 mg/kg). Even though there was a significant effect of storage time (P < 0.05) as expected, no significant (P >0.05) differences were observed between the four tested pad types over the 8-day testing period.
In study 2, (Chapter 4) a significant antioxidant effect (P < 0.05) was observed in L* values of ground chicken color between treatments. Milk mineral effectively preserved fresh color and slowed lipid oxidation in chicken patties by day 10. Inverse correlations (P < 0.001) were observed between pH (increasing), and lightness, redness values (decreasing) from day 1 through 10. Increased pH levels from slightly acidic to basic or physiological pH resulted in high numbers for total aerobic plate-counts. There was a significant antioxidant effect on lipid oxidation values by day 10; eugenol and MM were more effective (P < 0.05) than STPP in controlling lipid oxidation measured as thiobarbituric acid reactive substances (0.198 mg/kg, 0.198 mg/kg, and 0.268 mg/kg, respectively). In conclusion, CO2 generating absorbent pads did not have a positive effect on meat quality, while the antioxidant milk mineral efficiently maintained color, and pH, and controlled lipid oxidation and limited the growth of aerobic bacteria when compared to other antioxidants.

Creators: name: Kessler, James Andrew
Publisher: name: Utah State University
Year: 2014

description: Geothermal energy is being explored as a supplement to traditional fossil fuel resources to meet growing energy demand and reduce carbon emissions. Geothermal energy plants harvest heat stored in the Earth’s subsurface by bringing high temperature fluids to the surface and generating steam to produce electricity. Development of geothermal resources is often inhibited by large upfront risk and expense. Successful mitigation of those costs and risks begins with efficient characterization of the resource before development. A typically successful geothermal reservoir consists of a fractured reservoir that conducts hydrothermal fluids and a cap rock seal to limit convective heat loss through fluid leakage. The controls on the system include the density and orientation of fractures, mechanical rock properties, and the local stress field acting on those rocks.
The research presented in this dissertation utilizes diverse data sets to characterize core, wireline borehole logs, and laboratory data to describe the distribution of fractures, rock properties, and the orientation and magnitude of stresses acting on the borehole. The research demonstrates there is a potential resource in the region and describes the controls on the vertical extent of the hydrothermal fluids. The distribution of fractures is controlled by the distribution of elastic rock properties and rock strength. A cap rock seal is present that limits hydrothermal fluid loss from a fractured artesian reservoir at 1,745 m (5,726 ft). In addition to characterization of the resource, this research demonstrates that an equivalent characterization can be used in future exploration wells without the expense and risk of collecting core. It also demonstrates that multiple methods of analysis can be utilized simultaneously when some data are not available. Data collection from deep wellbores involves risk and data loss or tool failure is a possibility. In these cases, our methods show that successful characterization is still possible, saving time and money, and minimizing the financial risk of exploration
title: Identification of the Constraints and Barriers to the Adoption of Distributed Design Education

Publisher: name: Utah State University

description: The design field of landscape architecture has yet to witness the broad adoption of online education, despite multiple studies that have demonstrated the efficacy of online education in design fields, or distributed design education (DDE), in teaching design. While previous research has focused on the structural, institutional, social, and pedagogical aspects of DDE, little work has focused specifically on barriers to the adoption of DDE from a faculty perspective. This dissertation reports the results of a meta-synthesis of the current literature on DDE and a national Delphi study. A list of the identified constraints of DDE was created through the use of the meta-synthesis. This list of constraints was subsequently used in the creation of the Delphi study to identify the critical barriers to the adoption of online education in landscape architecture. There were 24 barriers assessed during the Delphi study, 7 of which were identified as critical barriers. Findings indicate that faculty remain skeptical of the precedents reported in the literature, do not receive adequate compensation for online course development, and have significant concerns about the ability of online education to replicate the social environment of the design studio. A comparison of the ranked barriers and the most commonly researched constraints suggests that the current research on DDE does not adequately address the concerns of faculty.
title: A Platform for False Data Injection in Frequency Modulated Continuous Wave Radar

Publisher: name: Utah State University

description: Radar is an acronym for RAdio Detection And Ranging. In general terms, it is a machine that uses radio waves for object-detection in its near periphery. It transmits radio waves in a known direction, which when intercepted by an obstruction/object are reflected by its surface and are received back at the radar system. The round trip delay time along with the known velocity of radio waves gives an accurate measurement of the distance of the object from the radar system. In a somewhat similar fashion, some radars are even capable of measuring the velocity of this object. Frequency-modulated continuous-wave (FMCW) radar is one such radar system, which is a subclass of continuous wave (CW) radars, where a continuous sinusoidal radio energy is transmitted, reflected, and received back at the radar system. These radar systems are widely used in vehicle automation technologies such as adaptive cruise control (ACC) and collision avoidance systems (CAS) to measure the distance from the nearest vehicles and maintain a safe following distance. But in designing these systems, little attention has been given to security, and these systems have vulnerabilities that are capable of compromising the whole purpose of making such systems.
In this work one such vulnerability in FMCW radar was exploited to design an attack that was capable of decreasing the apparent distance, as measured by a radar system. The attack was designed in such a way that there was no tampering with the radar system being attacked. Instead, false distance information was introduced in the return path of the transmitted radio wave by absorbing the original victim transmission and sending out a modified radio wave on the It was shown that the distance could be decreased to alarming values, which at the level of the vehicle automation system results in decreasing the speed of the automobile when actually it should have increased.

description: Homelessness among unaccompanied youth is a unique, yet pervasive, social problem. Youth often become homeless through three central pathways: conflict with family, involvement in the foster system, and involvement in juvenile justice systems. As youth experience homelessness during important developmental period(s), vulnerability to mental illness may occur if not already present. The present study examined the type and prevalence of mental illness. Characteristics of homelessness, health and mental health service utilization, and pathways to homelessness were examined in relation to the occurrence of mental illness. Findings indicated that a variety of characteristics are associated with mental illness. Mental health service utilization was also evaluated.

description: This work addresses the problem of detecting devices which are stealthily attached to the computer for logging keystrokes from keyboards. These devices are known as hardware keyloggers (HKL). When an HKL is attached to the keyboard, certain electrical characteristics of the keyboard signal are altered. Based on these characteristics (features), differences have been identified in an accurate assertion was made about the presence of HKL.
The characteristics from which the differences were obtained were used to make distributions and compared with distance-measuring methods. An experiment was done to collect data from a number of keyboards and form two distributions (training and test) to perform the comparison. It was possible to detect the presence of HKL in the keyboard with a minimum of 4 to 100 keystrokes.
For justifying the stability of the features, the temperature of the surroundings was obtained and the dependence of the features on temperature was obtained. Also, an experiment was done to see whether the keyboards were uniquely affected by the HKLs. This was done without using any training data, i.e., the distribution of features which was used did not come from a known state of the system (either with HKL or not with HKL).

description: Six nonlactating Holstein cows fitted with rumen and duodenal cannula were used to determine the efficacy of pH sensitive fatty acid polymer encapsulation as a means protecting amino acids from rumen fermentation and as a post-ruminal amino acid delivery system. The cows were arranged in a 2 x 2 factorial in a latin square design. Treatments were 1) the basal ration, and 2) basal ration plus rumen-protected lysine, methionine, and threonine at 10 g each per day.
Rumen parameters measured were pH, ammonia, volatile fatty acids, protozoa, liquid, and dry matter rate of passage, total viable bacteria, and viable cellulolytic bacteria. Duodenal parameters measured were crude protein, ammonia, and amino acid concentrations. Total tract apparent digestibility of nutrients was measured. In addition, rumen degradation of the three amino acid products was measured by loss from nylon bags, in the rumen.
Loss of product from nylon bags suggested the lysine and threonine products had no significant rumen protection, but that the methionine product had > 50% protection at 12 h in the rumen. None of the rumen parameters measured differed (P>.05) due to treatment. Duodenal crude protein and ammonia concentrations did not differ due to treatment. Duodenal amino acid concentrations were numerically higher for the amino acid supplemented treatment, but the differences were nonsignificant and thought to be confounded by failure of the lysine and threonine products. Total tract apparent nutrient digestibility was not affected by treatment.
A second experiment was conducted using 40 post-parturient Holstein cows, and different rumen-protected amino acid products from the first trial. Cows were nesteMwby treatment (control vs rumen-protected methionine 46 g and lysine 22 g) and parity (primiparous vs multiparous).
Dry matter intake and milk production were monitored daily, body weight weekly, and milk composition bi-weekly. Total tract apparent nutrient digestibility was measured during the last week of the 10-week trial.

description: Three experiments were conducted to evaluate low quality forages treatment by anhydrous ammonia (NH3) and(or) hydrogen peroxide (H2O2).
In experiment I, a control and three treatments of barley straw were compared: NH3, NH3 after rehydration of the straw with water (NH3+H2O), and NH3 after rehydration with a H2O2 solution (NH3+H2O2). Forages were fed, with a supplement, at two levels of intake (ad libitum and 75% of ad lib.). Treatments were administered in a split-plot in a Latin square design to 8 ewes. Total collections and rumen digesta measurements were made. Ammoniation, rehydration, and H2O2 increased primarily dry matter intake (DMI) but also digestibility of different nutrients. A similar trend was observed in rumen fermentation characteristics. Dry matter (DM) digestibility was slightly raised by limiting DMI. Digestible DMI (DDMI) was correlated with both the increase of forage CP content and the decrease of forage neutral detergent fiber. Water intake and output were highly correlated with fiber. Intake and digestibility better than acid detergent lignin insoluble ash (ADLIA). Both markers were adequate in determining hemicellulose digestibility.
In experiment II, ten solutions were prepared to rehydrate wheat straw. Six solutions were adjusted (with NaOH) to a pH of 9, 11, or 13 and contained 2% H2O2. Four solutions had a pH of 7 or 11 and contained no H2O2. Half of the straws were treated with NH3. In situ DM disappearance (DMD) of the different straws was measured at different times in 10 Holstein cows and three periods (Incomplete block design). The evolution of DMD was slow and almost linear. The positive effect of ammoniation on DMD was consistently apparent at all pH levels though depressed at pH 11. The effect of H2O2 was minor, but was complementary with ammoniation.
In experiment III, mature baltic rush (Juncus balticus Willd.) was either treated or not with NH3. Eight wethers had ad libitum access to the nonsupplemented forages in a cross-over design. total collections and rumen digesta measurements were made. DMI and DDMI were not affected by treatment, but DM digestibility was decreased by ammoniation.
title: Essays on the Determination of Equilibrium Real Exchange Rate for Taiwan, 1981-1993

description: Taiwan is one of the four smaller Asian economies. Before 1960, Taiwan pursued industrialization policies by limiting imports of manufactured goods, gradually adopting an open and outward-oriented economic policy, believing it would expend exports and yield gained ground.
With this increasingly open and outward-oriented economic policy as the background, we will study the real exchange rate (RER) misalignment in Taiwan over the period 1981-93. The RER plays a critical role in maintaining external competitiveness. Hence, from the policy point of view, this rate should not be allowed to deviate much from its equilibrium level. Since the equilibrium real exchange rate (ERER) is unobservable, it is very important that the concept be based on sound economic reasoning and its measurement should be done as correctly as possible.
It is generally agreed that misalignment in the RER has a negative effect on the economic performance of a country. This dissertation is divided into two essays. The first essay deals with the estimation of ERER by using the Edwards and the Elbadawi approaches and the measurement of the RER misalignment from two different approaches. The second essay investigates the empirical importance of the distinction between the permanent and temporary components of the determinants of the ERER. By using the same reduced form equation from the first essay and reestimating the ERER by employing the techniques of a modern time-series analysis, which is introduced by Steven Beveridge and Charles Nelson, an empirical analysis is presented of the RER behavior.

description: We present the first Hinode/EIS observations of 5 min quasi-periodic oscillations detected in a transition-region line (He II) and five coronal lines (Fe X, Fe XII, Fe XIII, Fe XIV, and Fe XV) at the footpoint of a coronal loop. The oscillations exist throughout the whole observation, characterized by a series of wave packets with nearly constant period, typically persisting for 4-6 cycles with a lifetime of 20-30 min. There is an approximate in-phase relation between Doppler shift and intensity oscillations. This provides evidence for slow magnetoacoustic waves propagating upwards from the transition region into the corona. We find that the oscillations detected in the five coronal lines are highly correlated, and the amplitude decreases with increasing temperature. The amplitude of Doppler shift oscillations decrease by a factor of about 3, while that of relative intensity decreases by a factor of about 4 from Fe X to Fe XV. These oscillations may be caused by the leakage of the photospheric p-modes through the chromosphere and transition region into the corona, which has been suggested as the source for intensity oscillations previously observed by TRACE. The temperature dependence of the oscillation amplitudes can be explained by damping of the waves traveling along the loop with multithread structure near the footpoint. Thus, this property may have potential value for coronal seismology in diagnostic of temperature structure in a coronal loop.

title: Three Essays on Labor Force Participation Rates Among the Fifty States, with Empirical Tests Using Panel Data
Creators: name: Groesbeck, John D.
Publisher: name: Utah State University
Year: 1993

description: This dissertation examined the theoretical foundations of an individual's labor force participation decision. Further, this dissertation provided empirical analysis of the impact of state tax rates, the duration of unemployment, and household size on male, female, and combined labor force participation rates of the fifty states from 1985 to 1990. Empirical tests showed that: 1) no significant relationship existed between tax variables and participation rates; 2) the duration of unemployment was positively related with participation rates while unemployment was negatively related; 3) service sector growth was positively correlated with longer durations of unemployment; and 4) household size was negatively related with female participation, although no significant relationship existed between household size and male participation rates.

description: We propose a method for reducing the spatial discretization error of coarse computational fluid dynamics (CFD) problems by enhancing the quality of low-resolution simulations using deep learning. We feed the model with fine-grid data after projecting it to the coarse-grid discretization. We substitute the default differencing scheme for the convection term by a feed-forward neural network that interpolates velocities from cell centers to face values to produce velocities that approximate the down-sampled fine-grid data well. The deep learning framework incorporates the open-source CFD code OpenFOAM, resulting in an end-to-end differentiable model. We automatically differentiate the CFD physics using a discrete adjoint code version. We present a fast communication method between TensorFlow (Python) and OpenFOAM (c++) that accelerates the training process. We applied the model to the flow past a square cylinder problem, reducing the error from 120% to 25% in the velocity for simulations inside the training distribution compared to the traditional solver using an x8 coarser mesh. For simulations outside the training distribution, the error reduction in the velocities was about 50%. The training is affordable in terms of time and data samples since the architecture exploits the local features of the physics.

description: We extend the construction of generalized Berezin and Berezin-Toeplitz quantization to the case of compact Hodge supermanifolds. Our approach is based on certain super-analogues of Rawnsley's coherent states. As applications, we discuss the quantization of affine and projective superspaces. Furthermore, we propose a definition of supersymmetric sigma-models on quantized Hodge supermanifolds. The corresponding quantum field theories are finite and thus yield supersymmetry-preserving regularizations for QFTs defined on flat superspace.

title: The Impacts of Privatization and Government Intervention in the Economy: An Empirical Analysis (Two Essays)
Creators: name: Al-Sumadi, Tayseer
Publisher: name: Utah State University
Year: 1998

description: In this dissertation, we provide empirical assessment of government involvement in economic activities. This assessment is done within the framework of a two-part strategy. In the first part, we evaluate the effects of the government size on the overall rate of economic growth of a group of 30 developing countries. This approach can be regarded as macroeconomic in the sense that the economywide growth is the subject of investigation. In the second part, we conducted a comparative study of technical efficiency between privately owned and publicly owned companies in the international oil industry. We refer to this approach as microeconomic since a particular industry is under investigation.
this dissertation consists of two essays. In the first essay, we examine the effect of government size, measured by the ratio of government consumption expenditures to gross domestic product (GDP) on the rate growth of GDP. Our sample includes 30 low-income and middle-income developing countries over the period 1970-90. We use a panel data approach to avoid the shortcomings of the cross-country models often used in such an analysis. The results indicate government size has a highly significant negative influence on the rate of economic growth. Therefore, privatization is viewed as a structural adjustment policy to overcome the negative effects of government size. However, we emphasize this policy can be effective only in the proper environment in a market-oriented economy with well-established political, social, and economic institutions, and a well-defined property right system. The essay provides some empirical evidence from a group of countries about the impact of privatization on the rate of economic growth.
In the second essay, we measure the firm-specific technical efficiency for a sample of 44 publicly owned and privately owned petroleum companies in the international oil industry. The empirical investigation is carried out by using the stochastic frontier production function approach. The results indicate the private decision-making units in the oil industry overperformed their publicly owned counterparts in terms of technical efficiency. The implication is privatization can improve the performance of the transformed public enterprises.
