description: Investigations of stellar encounters in cluster environments have demonstrated their potential influence on the mass and angular momentum of protoplanetary discs around young stars. In this study it is investigated in how far the initial surface density in the disc surrounding a young star influences the outcome of an encounter. Based on a power-law ansatz for the surface density, $Σ(r) \propto r^{-p}$, a parameter study of star-disc encounters with different initial disc-mass distributions has been performed using N-body simulations. It is demonstrated that the shape of the disc-mass distribution has a significant impact on the quantity of the disc-mass and angular momentum losses in star-disc encounters. Most sensitive are the results where the outer parts of the disc are perturbed by high-mass stars. By contrast, disc-penetrating encounters lead more or less independently of the disc-mass distribution always to large losses. However, maximum losses are generally obtained for initially flat distributed disc material. Based on the parameter study a fit formula is derived, describing the relative mass and angular momentum loss dependent on the initial disc-mass distribution index p. Generally encounters lead to a steepening of the density profile of the disc. The resulting profiles can have a r^{-2}-dependence or even steeper independent of the initial distribution of the disc material. From observations the initial density distribution in discs remains unconstrained, so the here demonstrated strong dependence on the initial density distribution might require a revision of the effect of encounters in young stellar clusters. The steep surface density distributions induced by some encounters might be the prerequisite to form planetary systems similar to our own solar system.

description: Bibliography: p. 104-108
description: Plane waves are an important class of multidimensional signals which are often en­countered in array signal processing applications such as, astronomy, radar/sonar, seismology, biomedical imaging, directional audio systems and wireless communica­tions. In many of these applications, it is of interest to selectively filter or enhance PWs on the basis of their space-time directions of arrival. A class of 2D/3D filters, commonly known as fan (velocity)/cone filters, has been extensively used in various fields of array signal processing applications to accomplish the above mentioned task. In this thesis two novel methods are proposed to reduce the computational complexity associated with the Finite Impulse Response (FIR) implementation of such filters. The first method takes into account the a priori knowledge of the dominant transients of fan/ cone impulse responses and the second method considers spatial undersampling as a means of complexity reduction. It is shown through simulation and numerical examples that both methods provide significant amount of computational savings.

The use of "contingent valuation method" for valuing medical services
Creators: name: Khan, Nassra
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 127-129
description: It is desirable to know how one can value goods that are not traded in a market, so there is no market price to indicate the economic value of the good. One way is to ask the users or potential users about the monetary value they would place on a particular public good. This method is called the 'contingent valuation method.' However, a number of questions have been raised about the validity and reliability of the results obtained through this method. This study tests the reliability of the contingent valuation method in valuing medical services by focusing on a cheap-talk design, which is thought to improve the reliability of responses given in a hypothetical contingent valuation study.
Physiological differentiation in swarming salmonella

description: Bibliography: p. 267-287
description: Swarming behaviour in bacteria has been traditionally described as a surface motility phenotype observed on laboratory media. Swarming motility is a collective behaviour of groups of bacterial cells, and unlike the classic swimming motility in broth, vegetative cells must first differentiate into elongated and hyperflagellated swarmer cells. The extent of the morphological changes associated with swarmer differentiation can vary significantly between different organisms. Recent studies indicate that swarmer differentiation represents much more than a motility phenotype, as several clinically important attributes are co-regulated with swarming. In this work, I demonstrate that swarmer differentiation in Salmonella enterica serovar Typhimurium is coupled to elevated resistance to a wide variety of structurally and functionally distinct classes of antibiotics. One mechanism of resistance was directly attributed to the up-regulation of the pmrHFIJKLM operon, and evidence was presented that other mechanisms are likely associated. Adaptive antibiotic resistance in the absence of overt selection suggests that swarmer differentiation may reflect the organism's adaptation to the host environment; not due to antibiotic use, but to the role of host-derived cationic peptides and resident microflora-derived colicins and toxic metabolites that shape the intestinal ecosystem. Proteomic analyses revealed that migrating swarmer cells are metabolically differentiated compared to the vegetative swimmer cells grown in the same nutrient environment. Furthermore, once the cells have differentiated, the swarmers remain in this physiological state under conditions that do not promote the initial differentiation. The permeability of the swarmers' outer membrane was predicted to be relatively reduced, which in part accounts for the multiple antibiotic resistance phenotype. Moreover, the bacterium's capacity to override some of the classic paradigms of metabolic regulation, established in aqueous environments, represents a unique physiological response by the pathogen that may be advantageous in polymicrobial environments such as the host. In addition, cell­cell signalling systems were differentially regulated, suggesting that the differentiated cells are also primed to respond to the presence of other organisms and its own increasing population. An experimental model system was developed to measure spatiotemporal gene expression patterns to study gene regulation in the context of transitions between cellular states.

Optative theatre: a critical theory for challenging oppression and spectacle
Creators: name: King, Donovan
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 251-262
description: The goal of this thesis is to develop a powerful new socio-theatrical paradigm for the 21st Century: the optative theatre. Exploring the state of oppression in the new millennium, the shortcomings of standard theatrical paradigms, and explosions in critical discourse and new technology, this thesis proposes that a new activist and user-based theatre is both necessary and desirable in order to overcome the dragooning of theatre, society, and humankind. Drawing primarily from the fields of Cultural and Theatre Studies, especially as they relate to Cultural Resistance and Global Justice, the Situationist notion of Spectacle is examined as an oppressive force that quagmires and devastates the whole of humanity. Critical thinking is provoked regarding human behaviour and dramatic performance on the world stage, and concepts of revolutionary theatre and theatrical revolution are examined in depth as they relate to Spectacle and the liberation of humanity. Based on the concept of counter-hegemonic playing, the highly activist optative theatre is portable, user-friendly, and free. Designed to inspire critical reflection and humanist transformation, optative theatre proposes that by adopting an anti-oppressive foundation to human identity, it is possible to employ theatre activism to challenge oppression in all its forms - by meta-theatrically playing the provocateur, and hence by living in action. With the ability to create instant virtual realities, optative theatre provides both a tool for critical reflection and a theatrical strategy for challenging oppression on personal, cultural, and structural levels of society. Furthermore, as a viral form of theatre, it has the potential to spread rapidly.
Switched boundary condition techniques in FDTD
Creators: name: Kivi, Jeremy
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 120-123
description: The Finite-Difference Time-Domain (FDTD) method is a numerical technique that is used to analyze complex electromagnetic problems. The memory requirement and time duration of a given FDTD simulation are critical issues that are consistently ad­dressed in research. Absorbing Boundary Conditions (ABCs) attempt to solve these issues by effectively extending the simulation domain to infinity. Current widely used boundary conditions like the Perfectly Matched Layer (PML) have high absorption characteristics however the memory and time required to use and implement this method is relatively high. A new boundary class is proposed that takes advantage of the time domain prop­erties of FDTD to construct an ABC with low memory requirement and compara­tively high absorption. This method involves a switched impedance that upconverts waves incident on the boundary to high frequency. This high frequency energy can then be removed from the simulation using the inherent attenuation properties of numerical dispersion in FDTD. A hybrid ABC is developed integrating the Switched Boundary Condition (XBC) with existing classical Mur and PML boundaries. The new XBC class is validated against existing ABCs over a set of test sim­ulations giving an overall performance evaluation of each boundary. The switched boundary implementations are found to offer complete absorption, however, this is only valid in specific FDTD cases. A hybrid, 1st order, switched Mur boundary is designed giving a general boundary solution with improved absorption over standard Mur and 4-layer PML in all simulation cases.

description: This study examined the role of arterial PO2 (PaO2) and PCO2 (PaCO2) in the regulation of brachial blood flow (BBF) in humans. Nine healthy male subjects participated in five 60-min experimental conditions: isocapnic hypoxia, isocapnic hyperoxia, euoxic hypocapnia, euoxic hypercapnia, and euoxia isocapnia (control). Dynamic end-tidal forcing was used to control end-tidal (i.e., arterial) PO2 and PCO2. Doppler ultrasound was used to measure BBF. Hypoxia elicited a sustained increase in BBF (25 ± 14%; P<0.05), whereas hyperoxia caused a sustained decrease in BBF (15 ± 8%; PO.05). Hypocapnia elicited a biphasic response, where BBF transiently increased (31 ± 17%; PO.05) after 2 min and abruptly declined (25 ± 14% below baseline) thereafter. During hypercapnia BBF initially increased (14 ± 10%; P<0.05), but returned to baseline values after 20 min. The present study provides direct evidence that alterations in PaO2 and PaCO2 have dynamic effects on blood flow regulation through the brachial artery. brachial blood flow, hypoxia, hyperoxia, hypocapnia, hypercapnia, euoxia, isocapnia

description: The formation of high mass stars is less well understood than that of lower mass stars due to the shorter time scales and larger distances involved. One of the earli­est stages of high mass star formation consists of a period of outflow which can be studied through its impact on its environment. We present observations of W28A2, a shell like Ultracompact HII region associated with one of the youngest and most energetic outflows in the Galaxy (05 star). Using the James Clerk Maxwell Tele­scope, we have observed the outflow in a number of transitions and have derived the age, mass, extent, and velocity of the outflow. In order to better constrain the driving mechanism of the outflow, we have conducted magneto-hydrodynamic simu­lations (using Zeus-MP and Jetget) of a high-velocity jet impacting on a surrounding molecular envelope.

description: Deep neural networks (DNNs) underpin many machine learning applications. Production quality DNN models achieve high inference accuracy by training millions of DNN parameters which has a significant resource footprint. This presents a challenge for resources operating at the extreme edge of the network, such as mobile and embedded devices that have limited computational and memory resources. To address this, models are pruned to create lightweight, more suitable variants for these devices. Existing pruning methods are unable to provide similar quality models compared to their unpruned counterparts without significant time costs and overheads or are limited to offline use cases. Our work rapidly derives suitable model variants while maintaining the accuracy of the original model. The model variants can be swapped quickly when system and network conditions change to match workload demand. This paper presents DNNShifter, an end-to-end DNN training, spatial pruning, and model switching system that addresses the challenges mentioned above. At the heart of DNNShifter is a novel methodology that prunes sparse models using structured pruning. The pruned model variants generated by DNNShifter are smaller in size and thus faster than dense and sparse model predecessors, making them suitable for inference at the edge while retaining near similar accuracy as of the original dense model. DNNShifter generates a portfolio of model variants that can be swiftly interchanged depending on operational conditions. DNNShifter produces pruned model variants up to 93x faster than conventional training methods. Compared to sparse models, the pruned model variants are up to 5.14x smaller and have a 1.67x inference latency speedup, with no compromise to sparse model accuracy. In addition, DNNShifter has up to 11.9x lower overhead for switching models and up to 3.8x lower memory utilisation than existing approaches.

Signal transduction of gonadotropin-releasing hormone-induced gonadotropin subunit and growth hormone gene expression in the goldfish pituitary
Creators: name: Klausen, Christian
Publisher: name: University of Calgary
Year: 2004

description: Bibliography: p. 129-145
description: Best known for its regulation of the production and secretion of pituitary gonadotropin hormones (GtHs), gonadotropin-releasing hormone (GnRH) is the central regulator of reproduction in all vertebrates. In mammalian and non-mammalian systems, the signaling pathways mediating GnRH-induced GtH and growth hormone (GH, fish only) secretion have been extensively studied. In contrast, much less is known about the mechanisms mediating GnRH-induced GtH subunit gene expression, especially in non­mammalian vertebrates. Moreover, the signaling pathways coupling GnRH receptor activation to increases in GH gene expression have not been investigated in any model system. The purpose of the present study was to investigate the signal transduction pathways that mediate GnRH-induced increases in GtH subunit and GH mRNA levels, with emphasis on the roles of protein kinase C (PKC) and extracellular signal-regulated kinase (ERK). The main hypothesis of this study was that the two native GnRHs use similar signal transduction pathways coupling GnRH receptors to GtH subunit and GH gene expression and release in the goldfish pituitary. Initial experiments revealed significant differences in the time- and dose-related effects of the two GnRHs in vivo and in vitro. Studies were then carried out to investigate the role of PKC in GnRH-induced GtH and GH gene expression in goldfish pituitary cells. Western blot analysis confirmed the presence of conventional, novel and atypical PK Cs in the goldfish pituitary. The results presented in this dissertation suggest a dual role for PKC in the regulation of GtH, but not GH, gene expression. Moreover, the data would appear to refute the hypothesis that conventional and novel PKCs are involved in GnRH-induced GtH and GH gene expression. The involvement of the ERK pathway in GnRH-stimulated GtH and GH gene expression was demonstrated using a combination of Northern and Western blot analysis. Although GnRH-induced GtH and GH gene expression is ERK-dependent, the data suggest a PKC-independent mechanism of activation. Together these results provide novel insights into the complexity and functional-specificity of GnRH signaling with respect to the regulation of secretion and gene expression in gonadotropes and somatotropes.
Feeding competition and group size in Central American howler monkeys (alouatta pigra) at Monkey River, Belize

description: Bibliography: p. 105-117
description: The Central American black howler (Alouatta pigra) occurs in surprisingly small social groups, for reasons that are not well understood. To test whether indirect within­group feeding competition constrains group size, I examined the effects of group size on day journey length, activity budgets, and group spread; compared food availability and dietary quality with energy expenditure; and evaluated the results in light of influential ecological constraints models. 45 full day follows were completed on 3 groups of wild A. pigra varying in size from 3 to 7 individuals. Food availability for all groups was similar, but group size was not associated with increased activity levels or day journey length, nor did any group experience variation in energy expenditure with changes in food availability, indicating that feeding competition is not acting to constrain group size at this site. Consequently, I suggest that other factors (possibly social ones) are responsible for small group size.

description: Bibliography: p. 102-112
description: This thesis attempts to harness the unique features of chaos theory and evolutionary com­putation to develop novel design methodologies for solving communication system design problems. The contributions of the thesis is two-fold. First, a novel design methodology based on genetic programming and DNA computation to improve the performance of con­ventional communication system was proposed. Second, it develops a non-coherent chaotic spread spectrum system that is robust to channel noise and distortions. The developed scheme has better performance over conventional spread spectrum system in realistic chan­nel environments. The application of the developed scheme to powerline communications in smart home networking was also investigated. Finally, a novel multilevel chaotic commu­nication that performs both modulation and spreading is proposed. Genetic programming was used to design the underlying chaotic system for this communication scheme. Theoret­ical formulations and extensive numerical analysis were performed to show the advantages of these schemes. The research work presented in this thesis can be viewed as a small step towards achieving the aforementioned goal.

description: Bibliography: p. 70-80
description: The purpose of the present study was to examine self-efficacy (SE), collective efficacy (CE), and cohesion (CO), and performance outcome (PO) in basketball teams (n=14). Another purpose was to examine whether the wording of CE questions (i.e., questions asked from a group [CEG] versus individual [CEI] perspective) would produce different research outcomes. Questionnaires were administered in the middle and at the end of the regular season. The results indicated that as SE beliefs about various basketball-related skills increase, CE beliefs about those skills increase, which predicts PO (while SE does not). Overall, the scores for both CEG and CEI subscales were stable over time. Although both were high, the CEG subscales obtained higher within-group agreement than did the CEI subscales. Both social and task cohesion were positively related to the CEG and CEI subscales. Finally, overall CEG was the sole predictor of PO. Implications of research findings are suggested.

description: Recent self-consistent mean-field calculations predict a substantial depletion of the proton density in the interior of 34Si. In the present study, we investigate how correlations beyond the mean field modify this finding. The framework of the calculation is a particle-number and angular-momentum projected Generator Coordinate Method based on Hartree-Fock-Bogoliubov+Lipkin-Nogami states with axial quadrupole deformation. The parametrization SLy4 of the Skyrme energy density functional is used together with a density-dependent pairing energy functional. For the first time, the generator coordinate method is applied to the calculation of charge and transition densities. The impact of pairing correlations, symmetry restorations and shape mixing on the density profile is analyzed step by step. All these effects significantly alter the radial density profile, and tend to bring it closer to a Fermi-type density distribution.

description: We study time-dependent perturbations to a family of five-dimensional black hole spacetimes constructed as a holographic model of the QCD phase diagram. We use the results to calculate two transport coefficients, the bulk viscosity and conductivity, as well as the associated baryon diffusion constant, throughout the phase diagram. Near the critical point in the T-mu plane, the transport coefficients remain finite, although their derivatives diverge, and the diffusion goes to zero. This provides further evidence that large-N_c gauge theories suppress convective transport. We also find a divergence in the low-temperature bulk viscosity, outside the region expected to match QCD, and compare the results to the transport behavior of known R-charged black holes.

description: The order of core genes on the chromosomes of Escherichia coli K12 and of Salmonella enterica serovar Typhimurium LT2 is strongly conserved. However, the chromosome of Salmonella enterica serovar Typhi is rearranged due to homologous recombination between the rrn operons. PCR analysis detected the exact order and orientation of the seven I-Ceul fragments between operons in 136 independent wild-type strains of S. Typhi. Rearrangements within cultures of S. Typhi are common but cells with rearrangements are lost from culture. However, in spite of many rearrangements in S. Typhi, the PCR data support both the genome balance and gene dosage hypotheses for genome conservation. SARB63, a wild-type S. Typhi strain, has an unbalanced genome and a reduced growth rate in LB medium, whereas the revertents produced from SARB63 are rearranged back towards genomic balance and also have improved growth rates. Comparison of the sequenced strains of enteric bacteria for the terminus region suggests Dif as an important site in the terminus region.

We find two general families of stable/unstable modes: (i) degenerate modes with symmetric and anti-symmetric patterns; (ii) single modes that are either symmetric or anti-symmetric. The concentration profiles of degenerate modes have strong peaks near the channel walls, while single modes diminish there. Once excited, both families would be detectable through high-speed imaging. We find that unstable modes occur in concentrated suspensions whose velocity profiles are sufficiently flattened near the channel centreline. The patterns of growing unstable modes suggest that they are triggered due to Brownian migration of particles between the central bulk that moves with an almost constant velocity, and highly-sheared low-velocity region near the wall. Modes are amplified because shear-induced diffusion cannot efficiently disperse particles from the cavities of the perturbed velocity field.

description: In this paper, the problem of semantic information extraction for resource constrained text data transmission is studied. In the considered model, a sequence of text data need to be transmitted within a communication resource-constrained network, which only allows limited data transmission. Thus, at the transmitter, the original text data is extracted with natural language processing techniques. Then, the extracted semantic information is captured in a knowledge graph. An additional probability dimension is introduced in this graph to capture the importance of each information. This semantic information extraction problem is posed as an optimization framework whose goal is to extract most important semantic information for transmission. To find an optimal solution for this problem, a Floyd's algorithm based solution coupled with an efficient sorting mechanism is proposed. Numerical results testify the effectiveness of the proposed algorithm with regards to two novel performance metrics including semantic uncertainty and semantic similarity.

Triggered di-hadron correlations in Pb--Pb collisions from the ALICE experiment
Creators: name: Adare, Andrew
Publisher: name: arXiv
Year: 2011
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Angular correlations between unidentified hadron trigger and associated particles are measured by the ALICE experiment for $0.5 < p_T^{t,a} < 15$ GeV, where $\ptt \geq \pta$. The pair correlation shapes are examined in a variety of centrality categories for pairs in $|η| < 1.0$ where $|η^t - η^a| > 0.8$. A series of two-particle Fourier components $V_{nΔ} \equiv $ are extracted from the long-range azimuthal correlation functions. The sum of $n<6$ terms match the data. For each $n$, a fit is applied over all $p_{T}$ bins simultaneously to test the collectivity hypothesis $V_{nΔ} \simeq v_n^t \, v_n^a$. The factorization holds at $p_{T}^{t,a}$ below approximately 4 GeV but breaks progressively at higher momenta. The divergence between the data and the global fit quantifies the onset of nonflow dominance in long-range correlations due to the away side jet. The $v_n$ values from the global fit are in close agreement with results from more established methods. At higher \pt where jet correlations dominate, the modification of conditional yields in central Pb--Pb collisions is measured with respect to $pp$ ($I_{AA}$) and with respect to peripheral events ($I_{CP}$). Significant suppression is observed on the side opposing the trigger, while a moderate enhancement is measured on the near side.

description: This thesis is concerned with effective project leadership. The main objective of this work is to support more effective project leadership by providing project managers with a stronger, more relevant and practical framework of key skills and competencies for specific project environments. Interest in project management has increased over the past several decades. Projects have become more prevalent and important within organizations and relied upon more heavily for organizational success; they have also become larger and more complex. These factors and others make projects more difficult to manage. At the same time, the effectiveness of the project manager is widely recognized as critical for project success, therefore it is essential to know which key skills and competencies are most important. Also, because projects can vary in terms of their characteristics and the work they require of the project manager to be successful, the required project manager skills and competencies may be very different for different projects. The research used three phases in the investigation. Phase 1, a Delphi Study, solicited the input of expert project professional about project manager skills, competencies, and project characteristics. Phase 2, focus groups, considered the potential fit of the project manager's work and the skills and competencies deemed most important from the perspective of the project manager and project sponsor. Phase 3, surveys, validated the findings from the prior research related to the importance of project manager skills and competencies and work. The results. of this investigation have provided new insight into key areas related to project manager effectiveness, revealing that the importance of project manager skills and competencies changes depending on the context in which the project is delivered. In general, "soft" skills and competencies are more often cited as very important than are "harder" or more technically focused skills and competencies. The research further showed discrepancy between the work of the project manager and the skills and competencies considered critical for them, as well as inconsistencies between the views of project managers and sponsors.
Acceleration of finite-difference time-domain electromagnetic simulations using graphics processor units

description: Bibliography: p. 65-66
description: The Finite-Difference Time-Domain (FDTD) method is used extensively in microwave engineering and optics for Electromagnetic (EM) simulations. However, FDTD runs too slowly for some simulations to be practical, especially when run on standard desktop computers, but even when run on clusters of computers or supercomputers. The suitability of Graphics Processor Units (GPUs) for the acceleration of FDTD has been investigated. It is demonstrated that consumer GPUs can be used to accelerate two-dimensional FDTD simulations by a factor of roughly seven, relative to compiler-optimized code running on an Intel CPU of similar technology generation. In order to demonstrate this acceleration, an off-the-shelf GPU has been programmed to solve three 2-dimensional electromagnetic problems: (i) a cavity resonator; (ii) a band­gap structure with periodic boundaries; and (iii) a waveguide with ceramic fingers and Perfectly Matched Layer (PML) boundaries. OpenGL is the Application Programming Interface (API) used to program the GPU.

description: This Master's Degree Project (MDP) looked at ways that the Calgary City Council and planners can foster market-rate housing developments in the City's central business district (CBD). The policy objects are two fold: to increase the vitality of the 'dead' downtown core after business hours and to decrease some of the pressure on suburban development leading towards a more sustainable city. The MDP's purpose was to describe some strategies that could work for the City to increase the number of residential units in the CBD after examining the approaches for other Canadian and American cities. Attitudinal interviews were held with some members of the downtown residential development industry and with some of the Aldermen who were available for comment. The conclusions drawn suggest that it may only be a matter of timing before the market in Calgary is at a stage where the CBD becomes attractive enough to support housing developments. Some citizens of Calgary are already beginning to see the benefits of living in downtown; whereas, it will just take longer for other to accept residences in the Central Business District.

We find a precise description of the antikaon-proton scattering amplitudes and are able to extract accurate values of the scattering lengths, a0=-1.81^+0.30_-0.28 + i 0.92^+0.29_-0.23 fm, a1=+0.48^+0.12_-0.11 + i 0.87^+0.26_-0.20 fm. We also discuss the two-pole structure of the Lambda(1405).
