Line-of-sight velocity dispersions and a mass distribution model of the Sa galaxy NGC 4594

description: In the present paper we develop an algorithm allowing to calculate line-of-sight velocity dispersions in an axisymmetric galaxy outside of the galactic plane. When constructing a self-consistent model, we take into account the galactic surface brightness distribution, stellar rotation curve and velocity dispersions. This algorithm is applied to a Sa galaxy NGC 4594 = M 104, for which there exist velocity dispersion measurements outside of the galactic major axis. The mass distribution model is constructed in two stages. In the first stage we construct a luminosity distribution model, where only galactic surface brightness distribution is taken into account. Thereafter, in the second stage we develop on the basis of the Jeans equations a detailed mass distribution model and calculate line-of-sight velocity dispersions and the stellar rotation curve. Here a dark matter halo is added to visible components. Calculated dispersions are compared with observations along different slit positions perpendicular and parallel to the galactic major axis. In the best-fitting model velocity dispersion ellipsoids are radially elongated. Outside the galactic plane velocity dispersion behaviour is more sensitive to the dark matter density distribution and allows to estimate dark halo parameters.

description: Sea ice plays an important role in the global climate system by impacting the energy balance of the Earth as well as affecting the oceanic and atmospheric circulations. Recently, large changes have been observed in the Earth's areal coverage of sea ice. However, little is currently known about sea ice thickness particularly at the scales needed for climate research. Spaceborne remote sensing provides the necessary global scale of coverage, but the retrieval of sea ice thickness from space has not been possible until recently with the launch of satellite altimeters of high accuracy and precision. The Ice, Cloud, and land Elevation Satellite (ICESat) is one such laser altimeter with the potential to retrieve the height of the snow plus ice layer above the water level, or sea ice freeboard. The combination of sea ice freeboard data with snow depth retrievals and the assumption of hydrostatic balance allows for the determination of sea ice thickness. The goal of this study is to use data from ICESat to provide sea ice thickness values at the global scale and high spatial resolution needed for climate studies. The work presented in this thesis includes the validation and improvement of ICESat data products, development and validation of sea ice freeboard retrieval algorithms using the ICESat data products, and the development of a method to combine ICESat freeboard retrievals with a snow depth data set to determine sea ice thickness at the 70 m spatial resolution of ICESat. The ICESat data set is used to study sea ice thickness, heat exchange, and ice production in the Arctic Ocean for the 2003-2008 time period. Despite the thinning of the Arctic sea ice cover over the 2003-2008 time period, mean ice growth rates for consecutive fall and winter measurement periods remained relatively constant. An increased ice growth rate which may be expected from a thinner ice cover appeared to be balanced by warmer temperatures. An increased ocean-atmosphere heat flux is also observed due to the thinning of the sea ice cover.

description: A weighted likelihood technique for robust estimation of a multivariate Wrapped Normal distribution for data points scattered on a p-dimensional torus is proposed. The occurrence of outliers in the sample at hand can badly compromise inference for standard techniques such as maximum likelihood method. Therefore, there is the need to handle such model inadequacies in the fitting process by a robust technique and an effective down-weighting of observations not following the assumed model. Furthermore, the employ of a robust method could help in situations of hidden and unexpected substructures in the data. Here, it is suggested to build a set of data-dependent weights based on the Pearson residuals and solve the corresponding weighted likelihood estimating equations. In particular, robust estimation is carried out by using a Classification EM algorithm whose M-step is enhanced by the computation of weights based on current parameters' values. The finite sample behavior of the proposed method has been investigated by a Monte Carlo numerical studies and real data examples.

description: This thesis documents the application of the Covariance Wavelet Transform (CWT) to lidar and, for the first time to our knowledge, wind profiler data to examine the possibility of accurate and continuous planetary boundary layer height (PBLH) measurements on short temporal resolution (one and fifteen minute averages respectively). Comparisons between PBLHs derived from the Elastic Lidar Facility (ELF) through application of the CWT and daytime radiosonde launches from Beltsville and RFK Stadium as part of the September 2009 NOAA/ARL and NCEP field study show an R2 = 0.84 correlation. PBLHs from ELF aided in diagnosing issues with the automatic PBLH calculation from Aircraft Communications Addressing and Reporting System (ACARS) profiles in the Real-Time Mesoscale Analysis used by plume dispersion modelers.  Determining the mixing in the PBL was one goal of a study of the spatial and diurnal variations of the PBL height over Maryland for July 2011, during NASA's Earth Venture mission DISCOVER-AQ. A semi-automated PBLH detection algorithm utilizing the CWT for wind profiler data was developed. This algorithm was tested on data from the 915 MHz wind profiler at Beltsville, Maryland, and compared against PBLHs derived from ground based radiosondes measured at Beltsville. Comparisons were also done between PBLHs derived from ground based lidars at UMBC and Beltsville. Results from the comparison show an R2 = 0.89, 0.92, and 0.94 correlation between the radiosonde PBLHs and the lidars and wind profiler PBLHs, respectively. Accurate determination of the PBLH by applying the CWT to lidar and wind profilers will allow for improved air quality forecasting and understanding of regional pollution dynamics.

description: 'Magic'-angle twisted bilayer graphene has received a lot of interest due to its flat bands with potentially non-trivial topology that lead to intricate correlated phases. A spectrum with flat bands, however, does not require a twist between multiple sheets of van der Waals materials, but rather can be realized with the application of an appropriate periodic potential. Here, we propose the imposition of a tailored periodic potential onto a single graphene layer through local perturbations that could be created via lithography or adatom manipulation, which also results in an energy spectrum featuring flat bands. Our first-principle calculations for an appropriate decoration of graphene with adatoms indeed show the presence of flat bands in the spectrum. Furthermore, we reveal the topological nature of the flat bands through a symmetry-indicator analysis. This non-trivial topology manifests itself in corner-localized states with a filling anomaly as we show using a tight-binding model. Our proposal of a single decorated graphene sheet provides a new versatile route to study correlated phases in topologically non-trivial, flat band structures.

Design and performance evaluation of a superscalar digital signal processor
Creators: name: Bagnordi, Hani
Publisher: name: University of British Columbia
Year: 2009

description: Multimedia applications are compute intensive applications that often contain multiple streams of operations such as audio and video running in parallel. These characteristics make them suitable for multi-stream processing through the use of parallel processing. In the first part of the thesis we evaluate the instruction and data bandwidth requirements of typical signal processing and multimedia functions. In the second part of the thesis we compare the advantages and disadvantages of programmable and algorithm specific integrated circuit digital signal processors. In order to accommodate the high level of instruction and data bandwidth found in multimedia applications we propose a superscalar digital signal processor (DSP) that can execute multiple instructions in parallel. A second feature of the proposed DSP is scalability. Scalability is an important feature needed to accommodate future increases in the performance requirements of multimedia applications. Our proposed DSP is also compatible with existing instruction-set architectures which eliminates the need for a specialized compiler. Next, we introduce a detailed analysis of the availability and distribution of instruction-level parallelism in ten existing multimedia applications. We also discuss the relationship between instruction-level parallelism and machine parallelism. In the following part of the thesis, we discuss machine parallelism and describe the different superscalar techniques used to fetch, decode, and execute multiple instructions per cycle. These techniques include out-of-order issue with out-of- order completion, register renaming, and branch prediction. A parameterizable superscalar simulator is used to simulate ten real-world multimedia applications on five different models of parallelism. The five models represent a wide range of machine parallelism, from a bare scalar machine to an ideal superscalar machine with unlimited parallelism. Results of the instruction- level parallelism study show that the multimedia benchmarks simulated contain a high level of parallelism in their code which make them suitable candidates for multiple-issue machines. In addition, this high level of instruction parallelism proves to be evenly distributed throughout the program which helps in maintaining a good balance between available parallelism and on-chip resources. Furthermore, machine parallelism simulation results show that instruction fetching places the ultimate limit on speedup and is the most critical factor in determining overall performance. However, by using aggressive branch prediction mechanisms and out-of-order issue with out-of-order completion techniques we are able to obtain a two to four fold increase in performance compared to a single issue scalar machine. Overall results show that abundant instruction parallelism combined with adequate machine parallelism proves to be a real performance booster for multimedia applications.

description: In this manuscript, we derive symmetry indicator formulas for the filling anomaly on 2D square lattices with and without time reversal, inversion symmetry, or their product, in the presence of spin-orbit coupling. We go beyond previous work by considering lattices with atoms occupying multiple Wyckoff positions. We also provide an algorithm using the Smith normal form that systematizes the derivation. The formulas determine the corner charge in 2D atomic or fragile topological insulators, as well as in 3D insulators and semimetals by studying their 2D slices. We apply our results to a 3D tight-binding model on a body-centered tetragonal lattice, whose projection into the 2D plane has two atoms in the unit cell. Our symmetry indicators correctly describe the higher-order hinge states and Fermi arcs in cases where the existing indicators do not apply.

description: Durch den demographischen Wandel in Verbindung mit fehlendem Pflegepersonal gewinnt die Entwicklung technischer Assistenzsysteme im Feld des Active and Assisted Living (AAL) zunehmend an Bedeutung. Zukunftsorientierte Instrumente, die in der Altenpﬂege zum Einsatz kommen, sind neuartige, nutzerzentrierte Gesundheitssysteme für Personengruppen mit speziellen Anforderungen. In diesem Beitrag werden das Konzept sowie erste Ergebnisse des Projekts AUXILIA gezeigt, welches ein nutzerzentriertes Assistenz- und Sicherheitssystem zur Unterstützung von Menschen mit Demenz auf Basis intelligenter Verhaltensanalyse beschreibt. Das Assistenz- und Sicherheitssystem richtet sich vor allem an Patienten mit beginnender Demenz. Das Projektziel ist der längere Verbleib von Demenzpatienten in ihren eigenen vier Wänden. Das System unterstützt nicht nur die Patienten, sondern richtet sich darüber hinaus an Nutzer aus dem Pﬂegeumfeld sowie an Angehörige. Mithilfe einer neuartigen Smart Sensor Technologie, die es ermöglicht, den gesamten Raum zu erfassen, können menschliche Verhaltensmuster bestimmt und an die Nutzergruppen weitergegeben werden. Basierend auf diversen Sensordaten werden Objekte kontextbasiert und selbstständig vom System erkannt und daraus Sicherheits- und Assistenzfunktionen, wie beispielsweise eine Sturzdetektion, abgeleitet. Neben der Entwicklung des Sensors wird untersucht, welchen Anforderungen eine Mensch-Maschine-Schnittstelle genügen muss, um für alle Nutzergruppen einen Mehrwert zu bieten.

description: Conformal field theories (CFT) play an important role in quantum field theories as they allow for exact studies that are hard to access without the conformal symmetries in place. A remarkable recent development is the application of conformal field theory to periodically driven systems, the so-called Floquet-driven CFTs. A number of recent works have found that there are classes of periodically driven (1+1)-dimensional CFTs that can be analytically solved, and that show both heating and non-heating phases, as well as unusual properties in terms of information scrambling. Hitherto, most results have focused on the dynamics of such models at stroboscopic times, i.e. samples taken at each period of the time evolution. In this paper, we consider time-evolution at arbitrary real times and derive formulas for the exact time-propagation of heating and non-heating classes of Floquet-driven CFTs. This requires a subtle treatment of non-stroboscopic time that leads to different interpretations in terms of curved space-time dynamics in these systems compared to previous results in the literature.

description: A number of direct detection experiments are searching for electron excitations created by scattering of sub-GeV dark matter. We present an alternate formulation of dark matter-electron scattering in terms of the dielectric response of a material. For dark matter which couples to electrons, this approach automatically accounts for in-medium screening effects, which were not included in previous rate calculations for semiconductor targets. We show that the screening effects appear for both scalar and vector mediators. The result is a non-negligible reduction of reach for direct detection experiments which use dielectric materials as targets. We also explore different determinations of the dielectric response, including first-principles density functional theory (DFT) calculations and a data-driven analytic approximation using a Mermin oscillator model.

description: Active particles break out of thermodynamic equilibrium thanks to their directed motion, which leads to complex and interesting behaviors in the presence of confining potentials. When dealing with active nanoparticles, however, the overwhelming presence of rotational diffusion hinders directed motion, leading to an increase of their effective temperature, but otherwise masking the effects of self-propulsion. Here, we demonstrate an experimental system where an active nanoparticle immersed in a critical solution and held in an optical harmonic potential features far-from-equilibrium behavior beyond an increase of its effective temperature. When increasing the laser power, we observe a cross-over from a Boltzmann distribution to a non-equilibrium state, where the particle performs fast orbital rotations about the beam axis. These findings are rationalized by solving the Fokker-Planck equation for the particle's position and orientation in terms of a moment expansion. The proposed self-propulsion mechanism results from the particle's non-sphericity and the lower critical point of the solute.

description: Die zunehmende Digitalisierung der Arbeitswelt bietet nicht nur vielversprechende Innovationen zur arbeiterzentrierten, adaptiven Aufgabengestaltung, sondern stellt den Einzelnen auch vor die Herausforderung, in höherem Maße mit digitaler Technik zu interagieren. Für die erfolgreiche Interaktion mit Technik sind zwei Faktoren ausschlaggebend: Wissen über bzw. Erfahrung mit technischen Systemen sowie Persönlichkeitsaspekte, die sich als Interaktionsstil im Umgang mit Technik manifestieren. Wir präsentieren das Konzept der interaktionsbezogenen Technikaffinität (affinity for technology interaction, ATI) als zentrale Ressource zum erfolgreichen Umgang mit Technik, und mit der ATI-Skala eine ökonomische und reliable Skala zur Quantifizierung der ATI eines Nutzers. Neben bestehenden Evaluationsergebnissen (N > 1500) stellen wir erste Ergebnisse einer Nutzerstudie vor, die im Rahmen des Projektes Factory2Fit durchgeführt wurde. Die Probanden interagierten mit 3D-Druckern und erlebten unterschiedliche Automatisierungsgrade des Prozesses. Zusätzlich zum Automatisierungsgrad wurde die Erfahrung der Probanden durch unterschiedliche Trainingsintensitäten variiert. Die Ergebnisse liefern erste Hinweise auf die Relevanz von ATI für die Vorhersage des Interaktionserfolgs mit Technologie und damit für Usability-Evaluationen in Industrie 4.0-Umgebungen.

description: A new method for community identification is proposed which is founded on the analysis of successive neighborhoods, reached through hierarchical growth from a starting vertex, and on the definition of communities as a subgraph whose number of inner connections is larger than outer connections. In order to determine the precision and speed of the method, it is compared with one of the most popular community identification approaches, namely Girvan and Newman's algorithm. Although the hierarchical growth method is not as precise as Girvan and Newman's method, it is potentially faster than most community finding algorithms.

description: In this thesis I examined the effectiveness of surfactant mediated Epitaxy in reducing the dislocation density when growing germanium on silicon for photodiode application and then compared to homoepitaxy of germanium on germanium.  The goal is to determine a method to integrate germanium photodiodes on employed silicon devices Analysis of the carrier concentration measurements show that the devices have the desired PIN structure with high levels of doping in both contact layers.  The current vs voltage measurements show the devices on both substrates have high defect densities.  This result suggests that the surfactant method does not achieve relaxation under the flux used and that the homoepitaxy was grown on an unclean surface or other non-ideal growth situations requiring further research.  Current vs. voltage under illumination shows that the devices responded to 1.55 micron light and have a theoretical responsivity of 91 mA/W.

description: Bei der Entwicklung handbetätigter Produkte mit ebenen Mechanismen spielen haptische Eigenschaften eine wichtige Rolle für die Kaufentscheidung des Kunden und sollten demnach so früh wie möglich in den Produktentwicklungsprozess einbezogen werden. Da CAD- und MKS-Modelle für die Simulation dieser nur bedingt geeignet sind, werden Prototypen hergestellt, welche hohe Kosten verursachen und bei Variantentests einen großen Zeitaufwand bedeuten. Deshalb kommen sogenannte haptische Feedbacksysteme als Werkzeug der virtuellen Produktentwicklung zum Einsatz. Hiermit lassen sich die ergonomischen Eigenschaften für verschiedene Modellvarianten frühzeitig ermitteln und mittels Nutzerstudien vergleichen. Das an der Professur Montage- und Handhabungstechnik entwickelte Ebene Force Feedback Interface (EFFI) wurde auf seine Eignung in dieser Hinsicht untersucht. Es kann gezeigt werden, dass die zuvor berechneten Bahnkurven vom Interface dargestellt werden können. Des Weiteren werden die haptischen Eigenschaften des Modells erfahrbar, wenn Nutzerkräfte am Griff angebracht werden. EFFI bietet somit das Potential ergonomische Studien bereits in einer frühen Entwicklungsphase durchführen zu können.

Marginally bound circular orbits in the composed black-hole-ring system

description: The physical and mathematical properties of the non-linearly coupled black-hole-orbiting-ring system are studied analytically to second order in the dimensionless angular velocity $M_{\text{ir}}ω_{\text{H}}$ of the black-hole horizon (here $M_{\text{ir}}$ is the irreducible mass of the slowly rotating central black hole). In particular, we determine analytically, to first order in the dimensionless ring-to-black-hole mass ratio $m/M_{\text{ir}}$, the shift $ΔΩ_{\text{mb}}/Ω_{\text{mb}}$ in the orbital frequency of the {\it marginally bound} circular geodesic that characterizes the composed curved spacetime. Interestingly, our analytical results for the frequency shift $ΔΩ_{\text{mb}}$ in the composed black-hole-orbiting-ring toy model agree qualitatively with the recently published numerical results for the corresponding frequency shift in the physically related (and mathematically much more complex) black-hole-orbiting-particle system. In particular, the present analysis provides evidence that, at order $O(m/M_{\text{ir}})$, the recently observed positive shift in the angular frequency of the marginally bound circular orbit is directly related to the physically intriguing phenomenon of dragging of inertial frames by orbiting masses in general relativity.

description: The demand for monoclonal antibodies in pharmaceutical drug production requires the highest technology be invested in obtaining a stable, high producing cell line. Currently the most common method of selection is by limiting dilution cloning, done in well plates. The highest producing cell is chosen after samples from the stationary plates have been analyzed for antibody production. The selection is based on stationary culture, even though after scale-up cells will grow in a stirred environment. This research investigates a way to test multiple clones in a stirred environment by using high throughput bioreactors (HTBRs) in the early stages of clone selection. It has been found that simply selecting subclones based on results from stationary culture could result in the chance of missing even higher producing clones. Instead, choosing a clone after analyzing its performance in a stirred environment is an improved method to select a cell line for further scale-up.
Similarity of wake characteristics for yawed wind turbines of utility-scale

description: This work is dedicated to studying the influence of yaw angle on the wake characteristics of a 2.5 MW utility-scale wind turbine using large-eddy simulations with the turbine's blades and nacelle parameterized as actuator surfaces. Four different yaw angles are simulated, i.e., $γ=0^{\circ},10^{\circ},20^{\circ},30^{\circ}$ for three different tip-speed ratios $λ= 7,8,9$. Similarities are observed for both time-averaged velocity fields and the turbulence statistics of turbine wakes. Specifically, it is found that the temporal average of the wake deflection, the velocity deficit and the transverse velocity, the Reynolds stresses, and the wake width defined using the velocity deficit can be properly scaled using the characteristic length and velocity scales depending on the thrust on the rotor and yaw angles. The width of the region influenced by the transverse velocity, the PDF of the instantaneous wake position, and the standard deviation of wake position and wake width, on the other hand, are scaled well using the rotor diameter independent of the yaw angles and tip-speed ratios. These results suggest that the wake of a yawed wind turbine can be decomposed into the streamwise and transverse components, and the turbine-added turbulence and the meandering motion of the wake can be decoupled from the wake deflection for the considered cases.
