▼ This thesis addresses aspects of the statistical inference problem for the semiparametric elliptical copula model. A copula (function) for a continuous multivariate distribution is the joint distribution function of the transformed marginal distributions, where the transformation is the probability integral transform. As such, copula is a tool to couple or decouple the multivariate dependence structure from the behaviors of the individual margins. The semiparametric elliptical copula model is the family of distributions whose dependence structures are specified by parametric elliptical copulas but whose marginal distributions are left unspecified. The elliptical copula is in turn uniquely characterized by a characteristic generator and a copula correlation matrix [SIGMA]. In the first part of this thesis, we address the estimation of [SIGMA]. A natural estimate for [SIGMA] is the plug-in estimator [SIGMA] with Kendall's tau statistic. We first obtain a sharp bound on the operator norm of [SIGMA] [-] [SIGMA]. Then, we study a factor model of [SIGMA], for which we propose a refined estimator [SIGMA] by fitting a lowrank matrix plus a diagonal matrix to [SIGMA] using least squares with a nuclear norm penalty on the low-rank matrix. The bound on the operator norm of [SIGMA] [-] [SIGMA] serves to scale the penalty term, and we obtain finite sample oracle inequalities for [SIGMA]. We provide data-driven versions of all our estimation procedures. In the second part of this thesis, we specialize to a subset of the semiparametric elliptical copula model and study the classification of two distributions that have the same Gaussian copula but that are otherwise arbitrary in high dimensions. Under this semiparametric Gaussian copula setting, we derive an accurate semiparametric estimator of the log density ratio, which leads to our empirical decision rule and a bound on its associated excess risk. Our estimation procedure takes advantage of the potential sparsity as well as the low noise condition in the problem, which allows us to achieve faster convergence rate of the excess risk than is possible in the existing literature on semiparametric Gaussian copula classification. We demonstrate the efficiency of our semiparametric empirical decision rule by showing that the bound on the excess risk nearly achieves a convergence rate of n[-]1/2 in the simple setting of Gaussian distribution classification.

▼ Purpose: 1) To determine if self-selected exercise using the StreetStrider meets ACSM guidelines for improving cardiorespiratory fitness and 2) to determine how self-selected exercise intensity using the StreetStrider compares to exercise on a stationary elliptical cross-trainer. Methods: Seven male (age 29.0 � 11.18 years) and eight female (age 27.5 � 11.29 years) adults performed three separate exercise tests, including a 30 minute test at a self-selected pace on both the StreetStrider and on a stationary elliptical cross-trainer as well as a maximal test using the elliptical cross-trainer. The subjects also completed an exercise enjoyment questionnaire after each of the two 30 minute exercise bouts. Results: It was found that self-selected exercise using the StreetStrider resulted in significantly greater heart rate (155 � 21.6 vs. 140 � 20.9 bpm; 85 � 9.8 vs. 77 � 10.5 %HRmax), V02 (30.5 � 3.65 vs. 27.0 � 5.76 mllkg/min; 71 � 10.1 vs. 63 � 15.2 %V02max), and caloric expenditure (11.5 � 3.23 vs. 10.2 � 3.50 kcal/min) than exercise using a stationary elliptical cross-trainer (p < .05). The exercise enjoyment questionnaire showed that there was no significant difference between enjoyment of exercise using the StreetStrider and exercise using the elliptical cross-trainer. Conclusion: Self-selected exercise using the StreetStrider meets current ACSM guidelines for improving cardiorespiratory fitness. Also, exercise using the StreetStrider elicited significantly greater HR, V02, and caloric expenditure responses in both men and women when compared to exercise on a stationary elliptical cross-trainer. Therefore, the StreetStrider seems to be an effective exercise modality for healthy adults especially those looking to improve cardiorespiratory fitness and control body weight. By using the StreetStrider regularly for exercise, healthy adults would be likely to experience the health and fitness benefits of physical activity.

▼ This thesis clarifies the role of disk components embedded in the spheroids of early type galaxies, with particular focus on the frequency and structure of disks in galaxies conventionally classified as "ellipticals". We discuss both photometric and spectroscopic means of assessing disks. Using simple photometric models, we explore what physical disk parameters result in detectable photometric signatures. We discuss in particular the deviations of the projected isophotes from perfect ellipses in disk/spheroid systems. We show that a wide range of intrinsic disk-to-spheroid ratios (D/S) can produce very similar photometric signatures, depending on viewing angle. We find the distribution of observed isophote distortions in a sample of ellipticals with published surface photometry to be consistent with the D/S hypothesis, implying that about half of the sample members could contain disks with D/S ∼ 0.25. To confront our models with a more suitable set of data, we obtained surface photometry at 0.4μ and 1.6μ for a statistical sample of about 80 galaxies, comprised of both E's and S0's. Analyzing this data set we find that in any given luminosity bin of early type galaxies, one third of the objects contain disks whose detectability depends on a favourably high inclination. This fraction was estimated independently from isophote distortions and from radial luminosity profiles. The apparent smooth transition between disk galaxies and purely spheroidal objects can be explained exclusively by changes in the viewing angle, even assuming two discrete classes of early type galaxies (either having substantial disks or none at all). There is no need to invoke continuity along the Hubble sequence from E's to S0's. For the members of this sample we find a considerable range in D/S, 0.15 < D/S < 5. However, most of that variation is caused by changes in the relative scale lengths rather than by changes in disk surface brightness. To analyze kinematic signatures of disk components we develop an optimal algorithm to extract the line-of-sight velocity distribution (LOSVD) from the broadening of absorption line spectra. Analyzing the LOSVD's in two kinematically distinct cores of elliptical galaxies, we find that they can be modelled dynamically as small disks embedded in the large spheroid. The range in rotational support, 1.3 < ν/σ < 4, of these disks suggests that some of them have formed dissipatively and others through a merger event.

▼ The flow-reversal elliptical cylindrical end chamber mufflers of short length are used often in the modern day automotive exhaust systems. The conventional 1-D axial plane wave theory is not able to predict their acoustical attenuation performance in view of the fact that the chamber length is not enough for the evanescent 3-D modes generated at the junctions to decay sufficiently for frequencies below the cut-off frequency. Also, due to the large area expansion ratio at the inlet, the first few higher order modes get cut on even in the low frequency regime. This necessitates a 3-D FEM or 3-D BEM analysis, which is cumbersome and time consuming. Therefore, an ingenious 1-D transverse plane wave theory is developed by considering plane wave propagation along the major-axis of the elliptical section, whereby a 2-port axially short elliptical and circular chamber muffler is characterized by means of the transfer matrix [T] or impedance matrix [Z]. Two different approaches are followed: (1) a numerical scheme such as the Matrizant approach, and (2) an analytical approach based upon the Frobenius series solution of the Webster’s equation governing the transverse plane wave propagation. The convective effects of mean flow are neglected; however the dissipative effects at the ports are taken into account. The TL predicted by this 1-D transverse plane wave analysis is compared with that obtained by means of the 3-D analytical approach and numerical (FEM/BEM) methods. An excellent agreement is observed between this simplified 1-D approach and the 3-D approaches at least up to the cut-on frequency of the (1, 1) even mode in the case of elliptical cylindrical chambers, or the (1, 0) mode in the case of circular cylindrical chambers, thereby validating this 1-D transverse plane wave theory. The acoustical attenuation characteristics of such short chamber mufflers for various configurations are discussed, qualitatively as well as quantitatively. Moreover, the Frobenius series solution enables one to obtain non-dimensional frequencies for determining the resonance peak and trough in the TL graph. The use of this theory is, however, limited to configurations in which both the ports are located along the major axis in the case of elliptical chambers and along the same diameter for circular chambers. The method of cascading the [T] matrices of the 2-port elements cannot be used to analyze a network arrangement of 2-port elements owing to the non-unique direction of wave propagation in such a network of acoustic elements. Although, a few papers are found in the literature reporting the analysis of a network of 2-port acoustic elements, no work is seen on the analysis of a network of multi-port elements having more than two external ports. Therefore, a generalized algorithm is proposed for analyzing a general network arrangement of linear multi-port acoustic elements having N inlet ports and M outlet ports. Each of these multi-port elements constituting the network may be interconnected to each other in an arbitrary manner. By… Advisors/Committee Members: Munjal, M L (advisor).

▼ Clustering is an important unsupervised classification technique. In supervised classification, we are provided with a collection of labeled (pre-classified) patterns and the problem is to label a newly encountered, yet unlabeled, pattern. At first, we consider clustering in Euclidean space in large dimensions. Then, we delve into the discrete setting of networks. We go into the issues related to network modeling and then into a specific method of clustering in networks. In the first chapter, we consider the problem of estimation and deriving theoretical properties of the estimators for the elliptical distributions. The class of elliptical distributions have distributions with varied tail behavior. So, estimation under class of elliptic distributions lead to automatic robust estimators. The goal of the chapter is to propose efficient and adaptive regularized estimators for the nonparametric component, mean and covariance matrix of the elliptical distributions in both high and fixed dimensional situations. An algorithm for regularized estimation of mixture of elliptical distributions will also lead to an algorithm for finding elliptical clusters in high dimensional space and such an approach is also given in the chapter. In clustering, one of the main challenges is the detection of number of clusters. Most clustering algorithms need the number of clusters to be specified beforehand. In chapter two, we propose a new method of selecting number of clusters, based on hypothesis testing. The study of networks has received increased attention recently not only from the social sciences and statistics but also from physicists,computer scientists and mathematicians. But a proper statistical analysis of features of different stochastic models of networks is still underway. In chapter three, we give an account of different network models and then we analyze a specific nonparametric model for networks. We consider the nonparametric estimate of link probabilities in dense social graphs in the context of network modeling and exploratory statistics.In chapter four, we also propose bootstrap methods for finding empirical distribution of count features or `moments' and smooth functions of these for the networks. Using these methods, we can not only estimate variance of count features but also get good estimates of such feature counts, which are usually expensive to compute numerically in large networks. In our paper, we prove theoretical properties of the bootstrap variance estimates of the count features as well as show their efficacy through simulation. We also use the method on publicly available Facebook network data for estimate of variance and expectation of some count features. In chapter five, we propose a clustering or community detection scheme for networks. One of the principal problem in networks is community detection. Many algorithms have been proposed for community finding but most of them do not have have theoretical guarantee for sparse networks and networks close to phase transition boundary proposed by…

▼ Major gas-poor (dry) merging between two comparably massive spheroidal galaxies are post u-lated to be the central mechanism responsible for the assembly of the most massive (M[subscript star,tot] ≥ 10¹¹ M[subscript ☉]) elliptical galaxies. Numerical simulations predict that these mergers may occur at late cosmic times and typically in dense environments. Previous work based on a complete sample of high-mass (M[subscript star] ≥ 5 x 10¹⁰ M[subscript ☉]) galaxies with z ≤ 0.12 selected from the Yang et al. (2007) SDSS Galaxy Group Catalog and analyzed for residual asymmetric features in SDSS r-band images provided a lower limit to the frequency of massive pairs with interaction signatures residing in groups and clusters with halo masses M[subscript halo] ≥ 2.5 x 10¹³ M[subscript ☉]. The tidal sgnatures of such interactions may often be too faint to be clearly detected at the sensitivity of SDSS imaging data. To improve constraints and test the identification of dry merging, we obtained V-band images 1.5 mag deeper than SDSS for a random selection of 27 pairs with no SDSS tidal signatures, plus a subset of six previously identified interactions. Using GALFIT image residuals, we visually identify interaction signatures with surface brightnesses down to ~26.5 mag arcsec⁻² at S/N ≥ 5. We confirmed 80% of previous interaction identifications based on shallower SDSS imaging, and identified three new systems with mutual tidal signatures that were previously classified as non-interacting. Applying these deeper statistics indicates that the merger frequency for massive pairs with projected separation ≤ 30kpc increases from 16 ± 3% to 23 ± 6% combined with the shallower imaging data. The merger frequency further increases to 35 ± 16%, when the massive pairs share the same dark matter halo and have similar redshifts. We found that using SDSS alone would underestimate the merger frequency by 30%. Advisors/Committee Members: McIntosh, Daniel H. (advisor).

Globular clusters are found in the halos of all types of galaxies, and have been shown to play major roles in the formation of stars and galaxies. The purpose of this thesis is to advance our level of understanding of the dynamical evolution of globular clusters through N-body simulations of clusters with a range of circular, eccentric, and inclined orbits. Theoretical studies have historically assumed that globular clusters experience a static tidal field, however the orbits of globular clusters are all non-circular and the tidal field of most galaxies is not symmetric. Understanding how clusters evolve in realistic potentials allows for them to be used to constrain the formation, merger history, and evolution of a host galaxy and even map out the current size, shape, and strength of a galaxy's gravitational field. We find that dense and compact clusters evolve as if they are in isolation, despite being subject to a non-static tidal field. For larger clusters, tidal shocks and heating inject energy into the cluster and significantly alter its evolution compared to previous studies. We describe how a non-static field alters the mass loss rate and relaxation time of a cluster, and propose methods for calculating a cluster's size and orbit. We then apply our work to clusters in the giant galaxies M87, NGC 1399, and NGC 5128. We consider each cluster population to be a collection of metal poor and metal rich clusters and generate models with a range of orbital distributions. From our models we constrain the orbital anisotropy profile of each galaxy, place constraints on their formation and merger histories, and explore the effects of nearby galaxies on cluster evolution. By advancing studies of globular cluster evolution to include the effects of a non-static tidal field, we have made an important step towards accurately modelling globular clusters from birth to dissolution. Our work opens the door for globular clusters to be used as tools to study galaxy formation, evolution, and structure. Future studies will explore how galaxy formation and growth via the hierarchical merger of smaller galaxies will affect cluster evolution.

▼ In this thesis, we explore 7.5 billion years of evolution in cluster galaxy star formation activity using a sample of 11 high-redshift (1 < z < 1.5) clusters from the IRAC Shallow Cluster Survey, and 25 low-redshift (0.15 < z < 1) clusters from The Cluster Lensing And Supernova survey with Hubble. We compare cluster galaxy star formation to that of the field over 0.15 < z < 1.5 using ~8000 galaxies from the UltraVISTA survey. Mid-infrared star formation rates are measured using Spitzer 24 μm data for isolated high-redshift galaxies. We calculate rest-frame ultraviolet star formation rates for low-redshift cluster members using Hubble Space Telescope observations. Using publically available mid-infrared and ultraviolet data for our field sample, we empirically derive scaling relations to adjust low-redshift cluster galaxy ultraviolet star formation rates to mid-infrared levels. We classify cluster galaxy morphology by visual inspection, and use quantitatively measured morphologies for field galaxies. Cluster late-type galaxies at z > 1 show enhanced star formation activity relative to the field, and account for nearly 90% of the overall star formation activity in high-redshift clusters. While high-redshift early-type galaxies are substantially quenched relative to cluster late-types, they still contribute ~13% of the total cluster star formation activity. With early-type fractions increasing from 34 to 56% from z ~ 1.5 → 1.16, we find that new cluster early-type galaxies are likely being formed around z ~ 1.4. The fraction of early-type galaxies that are star-forming drops from 29 to 11% over this period, yet their specific star formation rates are roughly constant. These factors suggest that the events that created these new galaxies, possibly mergers, were both recent and gas-rich. With typical coverages of 50% of z < 1 cluster virial radii, we can only probe the cores of low-redshift clusters. We find that in this regime, the star formation activity of cluster galaxies is quenched relative to the field. We compare the mean star formation rate of cluster galaxies to the results of Alberts et al. (2014), who fit the mean star formation rate evolution over 0.3 < z < 1.5, and measured star formation rates by stacking 250 μm Herschel images. We find excellent agreement between the Herschel-based fit and both our Spitzer-derived and ultraviolet → infrared star formation rates.

▼ Knowledge of the joint distribution is crucial for risk measure estimation, portfolio allocation, derivative pricing, to name but a few problems. The multivariate normal function, the most commonly used joint distribution, is not sufficient if data have features of fat tailed margins and co-extreme movements, which are commonly found in financial data. More flexible multivariate distributions are needed in order to address these features. The copula, originated by Sklar (1959) and also called the dependence function, can be combined with arbitrary marginal distributions to form various joint distributions. "Conditional copulae", proposed by Patton (2002a), are adopted by several researchers to introduce time-varying dependence beyond the existing time-varying variance-covariance. All the research thus far is focused on bivariate series. How to extend the models to higher dimension is not obvious. In the financial world, it is essential to develop models for high dimensional data that do not suffer the "curse of dimension" problem, but are still rich enough to capture the major data features, such as fat-tailed margins, volatility clustering, time-varying correlation and tail dependence. Motivated by Chen et al. (2004), we propose a model of "Elliptical Copulae with Dynamic Conditional Correlation" as the dependence model for some financial data. With additional information about the margins, the joint distribution is obtained in a straightforward way. Combining the good properties of copulae and DCC models, our model is especially attractive for high dimensional data. The general ideas of our model are as follows: each individual series is modelled by its own appropriate heteroskedasticity model, and standardized residuals are obtained after filtering out the estimated dynamic variance; then the standardized residuals are monotonically transformed to new ones as from the same univariate elliptical distribution; finally, the transformed residuals are used to build the dependence model of elliptical copulae with time-varying correlation from the corresponding elliptical DCC models. Our model is applied to two financial practices: VaR estimation and optimal portfolio allocation. The impacts of fat-tailed margins, time-varying correlation and tail dependence are investigated with two hypothetical portfolios. For VaR estimation, these data features have substantial importance; while for portfolio allocation, the effects are not so significant.

▼ The advancement of the structural steel manufacturing industry has led to the recent emergence of steel members with Elliptical Hollow Sections (EHS) and Semi Elliptical Hollow Sections (SEHS). Although these sections are gaining popularity among architects, the lack of design guidelines specifically tailored towards these sections inhibits their efficient structural use. Within this context, this thesis provides several steps towards the development of such guidelines. A review of the manufacturing process of hot-rolled steel sections is conducted with emphasis on hollow structural sections. The main factors affecting the formation of residual stresses during cooling of the sections are discussed. Lower bound plastic interaction relations for EHS subjected to combinations of axial force, bi-axial bending moments and torsion are then derived. The formulation is based on the lower bound theorem of plasticity and the maximum distortional energy density yield criterion. Its applicability for conducting the cross-sectional interaction check in structural steel design problems is illustrated through a practical example. A simplified and conservative interaction equation is then proposed based on curve fitting of the results of the lower bound solution. Upper bound interaction relations are next developed for EHS subjected to combinations of axial force, bi-axial bending moments, torsion and bimoments. The formulation is based on kinematically admissible strain fields within the context of the upper bound theorem of plasticity. The interaction relations derived successfully capture the effect of confining radial strains present at welded end sections, as well as sections that are free to deform in the radial direction away from end welded sections. An iterative solution technique is developed to solve the resulting highly non-linear system of interaction relations. The effects of residual stresses and initial imperfections on axial compressive resistance of hot-rolled EHS are then incorporated into the lower bound interaction relations. Towards that goal, the thermo-mechanical properties of steel were extracted from the literature. A thermo-mechanical finite element model was developed for prediction of residual stresses in rolled sections. The validity of the model was assessed by comparison against residual stress measurements available in the literature. The model is then applied to predict the residual stresses in hot-rolled EHS. A series of geometric and material nonlinear finite element analyses is conducted on columns of EHS sections. The analyses include predicted residual stresses and initial out-of-straightness imperfections in order to determine the inelastic buckling capacity of EHS members and generate column curves for EHS sections. The column curves are subsequently compared to those based on Canadian, American and European design codes. Two column curve equations are proposed in a format similar to that of the Canadian Standards for buckling about major and minor axes. The column curves were subsequently…

▼ Microwave tomography is a classical approach for non destructive evaluation. Microwave tomography has many biomedical applications such as brain imaging, temperature sensing in different biological tissues and breast cancer detection. In a microwave tomography system, numbers of radiators are used to transmit microwave signal into an object under test and the scattered fields are recorded. The collected data is used to quantitatively reconstruct the dielectric profiles of the object under test through inverse scattering mechanism. It has been shown that by using wide band data, highly stable and high resolution reconstructions can be obtained. Lower frequency components provide stability of the reconstructions, while higher frequency components contribute to the resolution. Accordingly, ultra wideband antennas are required in UWB microwave tomography systems. In addition to ultra wide bandwidth, the antennas in a microwave tomography system should be easy to model with computational program. In this thesis Printed elliptical monopole antenna (PEMA) is investigated for microwave tomography. It is a multi resonant antenna with simple structure and yield ultra wide bandwidth. The performances of a single antenna and an antenna array are studied. The reflection coefficients of the antenna, mutual coupling between antennas and energy distribution in the near field are obtained by means of simulations in CST microwave studio. The simulation result shows that reflection coefficients of the designed antenna are below -10dB over the entire frequency band of interest (1-4.5GHz), mutual coupling between antennas at different locations are below -20dB over the entire frequency band of interest and the designed antenna also has good electric field distribution in an array configuration which makes the radiated power concentrating in the imaging region. These results indicate that PEMA is a potential antenna for microwave tomography applications.
