description: Background Earlier studies have shown that balance training (BT) has the potential to induce performance enhancements in selected components of physical fitness (i.e., balance, muscle strength, power, speed). While there is ample evidence on the long-term effects of BT on components of physical fitness in youth, less is known on the short-term or acute effects of single BT sessions on selected measures of physical fitness. Objective To examine the acute effects of different balance exercise types on balance, change-of-direction (CoD) speed, and jump performance in youth female volleyball players. Methods Eleven female players aged 14 years participated in this study. Three types of balance exercises (i.e., anterior, posterolateral, rotational type) were conducted in randomized order. For each exercise, 3 sets including 5 repetitions were performed. Before and after the performance of the balance exercises, participants were tested for their static balance (center of pressure surface area [CoP SA] and velocity [CoP V]) on foam and firm surfaces, CoD speed (T-Half test), and vertical jump height (countermovement jump [CMJ] height). A 3 (condition: anterior, mediolateral, rotational balance exercise type) × 2 (time: pre, post) analysis of variance was computed with repeated measures on time. Results Findings showed no significant condition × time interactions for all outcome measures (p > 0.05). However, there were small main effects of time for CoP SA on firm and foam surfaces (both d = 0.38; all p 0.05). For CoD speed, findings showed a large main effect of time (d = 0.91; p 0.05). Conclusions Overall, our results indicated small-to-large changes in balance and CoD speed performances but not in CMJ height in youth female volleyball players, regardless of the balance exercise type. Accordingly, it is recommended to regularly integrate balance exercises before the performance of sport-specific training to optimize performance development in youth female volleyball players.

description: Refined simulation tools for wide field AO systems (such as MOAO,
MCOA or LTAO) on ELTS present new challenges. Increasing the number of degrees
of freedom (scales as the square of the telescope diameter) makes the standard
codes useless due to the huge number of operations to be performed at each
step of the AO loop process. This computational burden requires new approaches
in the computation of the DM voltages from WFS data. The classical matrix inversion
and the matrix vector multiplication have to be replaced by a cleverer iterative
resolution of the Least Square or Minimum Mean Square Error criterion (based on
sparse matrices approaches).
Moreover, for this new generation of AO systems, concepts themselves will become
more complex: data fusion coming from multiple Laser and natural guide
stars will have to be optimized, mirrors covering all the field of view associated
to dedicated mirrors inside the scientific instrument itself will have to be coupled
with split or integrated tomography schemes, differential pupil or/and field rotations
will have to be considered, etc
All these new entries should be carefully simulated, analyzed and quantified in
terms of performance before any implementation in AO systems.
In this paper we present a new E2E simulator, developed to deal with all these specific
ELT challenges. It is based on an iterative resolution of the linear model with
high number of degrees of freedom (using the sparse matrix) and includes new
concepts of filtering and coupling between LGS and NGS to effectively manage
modes such as tip / tilt and defocus in the entire process of tomographic reconstruction.

description: We present DLSCL J0916.2+2951 (z=0.53), a newly discovered major cluster merger in which the collisional cluster gas has become dissociated from the collisionless galaxies and dark matter. We identified the cluster using optical and weak lensing observations as part of the Deep Lens Survey. Our follow-up observations with Keck, Subaru, Hubble Space Telescope, and Chandra show that the cluster is a dissociative merger and constrain the dark matter self-interaction cross-section σ_{DM}m_{DM}^{-1}\leq7 cm^2g^{-1}. The system is observed at least 0.7\pm0.2 Gyr since first pass-through, thus providing a picture of cluster mergers 2-5 times further progressed than similar systems observed to date. This improved temporal leverage has implications for our understanding of merging clusters and their impact on galaxy evolution.

description: Updated results obtained from simulations of a single-conjugated adaptive optics (SCAO)
system for a 42 m telescope are presented in this work. The modulated pyramid wavefront sensor (PWFS),
which has been preferred in some projects for its versatility and sensitivity, is used in these simulations.
The main objective of this work is to evaluate the performance of such SCAO system under different
parameters (loop gain, modulation, truncated SVD mode), sensing wavelengths, atmospheric coherence
lengths and NGS magnitudes. Always measuring the Strehl ratio in the K-band, we have verified that the
overall performance tends to be poorer as the sensing wavelength becomes shorter. The loop gain optimal
range is dependent on the SVD truncation threshold used to build the command matrix, and a nonmodulated
PWFS produces in general poorer results when compared to modulated cases, being this
especially true for the R-sensing band. The default atmospheric model adopted was a von Kárman with
r0=0.13 m (@ 500 nm) and outer scale of 25 m, but poorer and better seeing conditions have also been
tested. We also show how the Strehl is affected by the incidence of different photon fluxes at the PWFS
detector and by the system working in different frame rates.
Essays on transportation economics and policy
Creators: name: Wan, Yulai
Publisher: name: University of British Columbia

description: This dissertation focuses on two major topics in transportation. The first one is related to hinterland accessibility of seaports. We analytically examine the interaction between urban road congestion and competition of two seaports on a common hinterland. An increase in road capacity by a chain will improve its port’s profit while reducing the rival port’s profit. The impact of levying road tolls and the optimal road pricing rules are also discussed. Given the above theoretical predictions, we empirically investigate the impacts of hinterland access conditions, especially urban road congestion, on the competition between as well as efficiency of major container ports in the United States. We find that more delays on urban roads may cause shippers to switch to competing rival ports. Adding local roads tends to benefit the port and harm its rival (in terms of throughput) by reducing road congestion. In general, there is a negative association between road congestion around the port and port productivity. However, this relationship tends to be negligible for primary ports of entry which enjoy substantially larger container throughput volume. We further investigate the strategic investment decisions of local governments on inland transportation infrastructure in the context of seaport competition. The two seaports and the common hinterland belong to three independent local governments, each determining the level of investment for its own inland transportation system. We examine the non-cooperative optimal investment decisions made by local governments, as well as the equilibrium investment levels under various coalitions of local governments. The second topic is related to airport congestion pricing. We study airport pricing with aeronautical and non-aeronautical services, incorporating the connection between congestion delay and consumption of non-aeronautical services (an aspect that has been neglected by previous studies), and the effect of passenger types. The resulting pricing rule includes two extra terms missing in the literature. Then, we model terminal congestion and runway congestion separately to accommodate their respective characteristics and identify a number of aspects in the optimal pricing rule which differ from those in the literature.

description: In the frame of the design of instruments for Extremely Large Telescopes, new techniques of Adaptive Optics have been developed. These techniques, generically called Wide Field Adaptive Optics (WFAO), are based on a tomographic reconstruction of the turbulent volume followed by a projection onto Deformable mirrors (DM) in order to ensure a good correction in a specified field of view (FoV). All these systems require a representation of the turbulent volume through the knowledge of the Cn2 profile. It matters both for an accurate simulation of the input perturbations in the case of performance analysis and system design, but also for an efficient model description in the tomographic reconstruction process. We discuss and analyze the impact of the structure and the complexity of the real Cn² profile onto the WFAO performance. We demonstrate that a classical integrated parameter is not sufficient and that a more complex criterion is mandatory. Then, we focus on the impact of Cn² model error in the tomographic reconstruction process with respect to the input profile. We demonstrate that number and position of layers are two critical parameters. In conclusion, we show that it is critical to have access to high resolution Cn² profile to ensure a good performance evaluation of a WFAO system.

description: We have explored the feasibility of using the MRF polishing technique to produce large
phase plates such as the 742x386mm phase plate required for NFIRAOS. QED Technologies’ MRF
polishing machines can produce phase plates as large as 1100x900mm. This technology allows
predetermined phase screen profiles to be polished onto glass substrates, yielding phase plates with welldefined
turbulence profiles that are durable enough to be used in the cooled (-35C) NFIRAOS AO system
for TMT. We present the measurements that we have obtained on a 200x200mm pathfinder prototype,
manufactured by QED Technologies on a N-BK7 substrate. We find that the synthetic turbulence has the
prescribed structure down to a spatial scale of 5mm. For scales smaller than 5mm and down to 0.5mm we
measured about 20% less structure than prescribed making the generated turbulence useful even at those
scales. Based on these results, we conclude that MRF polishing appears to be a very promising technique
for producing large turbulence phase plates for ELT-class AO systems.

description: We study SL(N,R) Chern-Simons gauge theories in three dimensions. The choice of the embedding of SL(2,R) in SL(N,R), together with asymptotic boundary conditions, defines a theory of higher spin gravity. Each inequivalent embedding leads to a different asymptotic symmetry group, which we map to an OPE structure at the boundary. A simple inspection of these algebras indicates that only the W_N algebra constructed using the principal embedding could admit a unitary representation for large values of the central charge.

description: We find a family of novel supersymmetric phases of the D1-D5 CFT, which in certain ranges of charges have more entropy than all known ensembles. We also find bulk BPS configurations that exist in the same range of parameters as these phases, and have more entropy than a BMPV black hole; they can be thought of as coming from a BMPV black hole shedding a "hair" condensate outside of the horizon. The entropy of the bulk configurations is smaller than that of the CFT phases, which indicates that some of the CFT states are lifted at strong coupling. Neither the bulk nor the boundary phases are captured by the elliptic genus, which makes the coincidence of the phase boundaries particularly remarkable. Our configurations are supersymmetric, have non-Cardy-like entropy, and are the first instance of a black hole entropy enigma with a controlled CFT dual. Furthermore, contrary to common lore, these objects exist in a region of parameter space (between the "cosmic censorship bound" and the "unitarity bound") where no black holes were thought to exist.

description: We introduce a matrix product state (MPS) with an incommensurate periodicity by applying the spin-rotation operator of each site to a uniform MPS in the thermodynamic limit. The spin rotations decrease the variational energy with accompanying translational symmetry breaking and the rotational symmetry breaking in the spin space even if the Hamiltonian has the both symmetries. The optimized pitch of rotational operator reflects the commensurate/incommensurate properties of spin-spin correlation functions in the $S=1/2$ Heisenberg chain and the $S=1/2$ ferro-antiferro zigzag chain.

Creators: name: Finlay, Heather
Publisher: name: Electronic version published by Vancouver Island University
Year: 2023
Subjects: subject: Inclusive education

description: A continuing problem in inclusive education is the inconsistent and often minimal access to learning due to persistently low expectations for students with extensive support needs (ESN) that as a result detrimentally impact student growth and outcomes. This is in part due to conflicting research in the field, and the challenge with identifying evidence-based practices (EBPs) for this population. The purpose of my research study is to provide a multi-perspective understanding of effective learning for students with profound disabilities. Using an explanatory sequential mixed methods design this study explores the question: “What constitutes effective learning for students with extensive support needs and how do multiple stakeholder perspectives enhance this understanding?” Descriptive statistics and coding were used to interpret and analyze data in the following topics: physical accessibility of school environments, values and attitudes towards learning and placement, academic and social learning, student engagement and growth, evidence-based practices, and barriers to learning. Throughout the data analysis stakeholders’ knowledge, thoughts, and perspectives were compared. This study ultimately found that the multi-perspective lens of the school-based team, as well as parents has led to a better understanding of the importance of flexible, student-centered, and strength-based learning opportunities supported by EBPs and how critical this understanding is in supporting the unique learning needs of students with complex needs. One key theme was woven throughout the findings, the importance of all educational stakeholders along with parents working alongside each other by sharing their unique insights to support the effective learning of students with extensive support needs.

description: All observing operations for the astronomy of the third millennium are planned to be done in Service
Mode at the new generation ground-based facilities (ELTs). This will permit to select, in a dynamic queue (called
flexible-scheduling), the most suitable observing program and instrumentation for a particular temporal window
as a function of the status of the optical turbulence that mainly affects the wavefront perturbations. It follows
that, to optimize the flexible-scheduling of scientific observations, the optical turbulence forecast is mandatory,
particularly when observations concern adaptive optics (AO) facilities. Without such a tool the risk is that all
potential advantage provided by an AO facility can be neutralized. In this contribution we review the principle of
the technique of the optical turbulence prediction with non-hydrostatic atmospherical meso-scale models as well
as its most important challenges. Besides we present the progress we recently obtained applying these models to
top class astronomical sites.

description: We apply a von Zeipel gravity darkening model to corotating binaries to obtain a simple, analytical expression for the emergent radiative flux from a tidally distorted primary orbiting a point-mass secondary. We adopt a simple Roche model to determine the envelope structure of the primary, assumed massive and centrally condensed, and use the results to calculate the flux. As for single rotating stars, gravity darkening reduces the flux along the stellar equator of the primary, but, unlike for rotating stars, we find that gravity brightening enhances the flux in a region around the stellar poles. We identify a critical limiting separation beyond which hydrostatic equilibrium no longer is possible, whereby the flux vanishes at the point on the stellar equator of the primary facing the companion. For equal-mass binaries, the total luminosity is reduced by about 13 % when this limiting separation is reached.

description: The Indigenous people of Canada's Northwest Territories have been undeniably affected by colonialism. These effects have caused Trauma and Intergenerational Trauma within the populations of people that reside here. Educators need to be prepared for the reality of teaching in this context and approaches that prepare students to deal with mental health challenges. Looking to the inherent strengths of Indigenous culture, knowledge, and values for solutions helps repair the damage that has been caused. Educators that are familiar with these things strengthen their practice and make learning more meaningful for students.

description: An ultracold gas of interacting fermionic atoms in a three-dimensional optical lattice is considered, where the lattice potential strength is periodically modulated. This non-equilibrium system is non-perturbatively described by means of a Keldysh-Floquet-Green's function approach for Mott-Hubbard systems employing a generalized dynamical mean field theory (DMFT). Strong repulsive interactions between different atoms lead to a Mott insulator state for the equilibrium system, but the additional external driving at zero temperature yields a non-equilibrium quantum critical behavior, where an infinite number of Floquet states arise and a transition to the liquid and conducting phase is given.

description: A new computational scheme for the nonlinear cosmological matter power spectrum (PS) is presented. Our method is based on evolution equations in time, which can be cast in a form extremely convenient for fast numerical evaluations. A nonlinear PS is obtained in a time comparable to that needed for a simple 1-loop computation, and the numerical implementation is very simple. Our results agree with N-body simulations at the percent level in the BAO range of scales, and at the few-percent level up to $k ~ 1$ h/Mpc at $z >= 0.5$, thereby opening the possibility of applying this tool to scales interesting for weak lensing. We clarify the approximations inherent to this approach as well as its relations to previous ones, such as the Time Renormalization Group, and the multi-point propagator expansion. We discuss possible lines of improvements of the method and its intrinsic limitations by multi streaming at small scales and low redshifts.

Namely we check the correspondence between the SU(2) Nekrasov partition function on $\mathbb{R}^{4}/\mathbb{Z}_{4}$ and the conformal blocks of the $S_{3}$ parafermion algebra (in $S$ and $D$ modules). We find that they are equal up to the U(1)-factor as it was in all cases of AGT-like relations. Studying the structure of the instanton partition function on $\mathbb{R}^4/\mathbb{Z}_p$ we also find some evidence that this correspondence with arbitrary $p$ takes place up to the U(1)-factor.

description: Wide Field Adaptive Optics (WFAO) systems require a precise reconstruction of the turbulent volume.
The C2n profile, representing the turbulence strength, becomes a critical parameter for the final tomographic
reconstruction performance. We present a new method, CO-SLIDAR (COupled SLope and scIntillation Detection
And Ranging), that uses correlations of slopes and scintillation indexes recorded on a Shack-Hartmann (SH),
to retrieve the C2n profile. A design is proposed for the instrument. Reconstruction performances are showed in
simulation. Tests are carried out on the optical bench, and improvements are suggested. Sensitivity of the method
to outer scale is demonstrated.
Life cycle monitoring of composite aircraft components with structural health monitoring technologies
Creators: name: Buchinger, Valentin
Publisher: name: Imperial College London

description: Life cycle monitoring could considerably improve the economy and sustainability of composite aircraft components. Knowledge about the quality of a component and its structural health allows thorough exploitation of it’s useful life and offers opportunity for optimization. Current life cycle monitoring efforts can be split in two main fields 1) process monitoring and 2) structural health monitoring with little overlap between them. This work aims to propose an integral monitoring approach, enabling entire life monitoring with the same sensor. First, the state of the art of both composite manufacturing as well as structural health monitoring technologies is presented. Piezoelectric sensors have been ruled out for further investigation due their brittleness. Fiber optical sensors and electrical property-based methods are further investigated. Distributed fiber optic sensors have been successfully used in composite manufacturing trials. Two processes were demonstrated: vacuum assisted resin transfer molding and resin infusion under flexible tooling. Due to their flexibility, optical fibers can survive the loads occurring during manufacturing and deliver valuable insights. It is shown for the first time numerically and experimentally, that fiber bed compaction levels and volume fractions can be calculated from the optical frequency shift measured by the optical fiber sensors. The same sensor was used for subsequent structural health monitoring. This proves that the gap between process monitoring and structural health monitoring can be closed with mutual benefits in both areas. The final chapter presents a novel electrical property-based sensing technique. The sensors are highly flexible and manufactured with a robot-based 3D-printing method. They are shown to reliably work as strain sensors and crack detectors. This work presents a thorough investigation of available and novel sensing technologies for process monitoring and structural health monitoring settings. The results obtained could pave the way to more efficient aircraft structures.

description: Thanks to averaging processes and Gamma-convergence techniques, we are able to link a microscopic description of ferromagnetic materials based on spin lattices and their mesoscopic description in the static framework for the three fundamental contributions: exchange, magnetostatic and external field. The results are in accordance with the classical continuous description of ferromagnetic phenomena and justifies it. This work is a seed towards a dynamic description of ferromagnetic materials.
Harnessing FPGA technology for rapid circuit debug
Creators: name: Hung, Eddie
Publisher: name: University of British Columbia
Year: 2013

description: Electronic devices have come to permeate every aspect of our daily lives, and at the heart of each device is one or more integrated circuits. State-of-the art circuits now contain several billion transistors. However, designing and verifying that these circuits function correctly under all expected (and unexpected) operation conditions is extremely challenging, with many studies finding that verification can consume over half of the total design effort. Due to the slow speed of logic simulation software, designers increasingly turn to circuit prototypes implemented using field-programmable gate array (FPGA) technology. Whilst these prototypes can be operated many orders of magnitude faster than simulation, on-chip instruments are required to expose internal signal data so that designers can root-cause any erroneous behaviour. This thesis presents four contributions to enable rapid and effective circuit debug when using FPGAs, in particular, by harnessing the reconfigurable and prefabricated nature of this technology. The first contribution presents a post-silicon debug metric to quantify the effectiveness of trace-buffer based debugging instruments, and three algorithms to determine new signal selections for these instruments. Our most scalable algorithm can determine the most influential signals in a large 50,000 flip-flop circuit in less than 90 seconds. The second contribution of this thesis proposes that debug instruments be speculatively inserted into the spare capacity of FPGAs, without any user intervention, and shows this to be feasible. This proposal allows designers to extract more trace data from their circuit on every debug turn, ultimately leading to fewer debug iterations. The third contribution presents techniques to enable faster debug turnaround, by using incremental-compilation methods to accelerate the process of inserting debug instruments. Specifically, our incremental optimizations can speed up this procedure by almost 100X over recompiling the FPGA from scratch. Finally, the fourth contribution describes how a virtual overlay network can be embedded into the unused resources of the FPGA device, allowing debug instruments to be modified without any form of recompilation. Experimental results show that a new configuration for a debug instrument with 17,000 trace connections can be made in 50 seconds, thus enabling rapid circuit debug.

Muon-Induced Background Study for an Argon-Based Long Baseline Neutrino Experiment

description: We evaluated rates of transversing muons, muon-induced fast neutrons, and production of $^{40}$Cl and other cosmogenically produced nuclei that pose as potential sources of background to the physics program proposed for an argon-based long baseline neutrino experiment at the Sanford Underground Research Facility (SURF). The Geant4 simulations were carried out with muons and muon-induced neutrons for both 800 ft (0.712 km.w.e.) and 4850 ft levels (4.3 km.w.e.). We developed analytic models to independently calculate the $^{40}$Cl production using the measured muon fluxes at different levels of the Homestake mine. The muon induced $^{40}$Cl production rates through stopped muon capture and the muon-induced neutrons and protons via (n,p) and (p,n) reactions were evaluated. We find that the Monte Carlo simulated production rates of $^{40}$Cl agree well with the predictions from analytic models. A depth-dependent parametrization was developed and benchmarked to the direct analytic models. We conclude that the muon-induced processes will result in large backgrounds to the physics proposed for an argon-based long baseline neutrino experiment at a depth of less than 4.0 km.w.e.

description: The future large telescopes will be certainly equipped with Multi-Conjugate Adaptive Optics systems. The
optimization of the performances of these techniques requires a precise specification of the different
components of these systems. Major of these technical specifications are related to the atmospheric turbulence
particularly the structure constante of the refractive index C2n(h) and the outer scale L0(h). New techniques based
on the moon limb observation for the monitoring of the C2n(h) and L0(h) profiles with high vertical resolution
will be presented. A new monitor PBL (Profileur Bord Lunaire) for the extraction of the C2n(h) profile with high
vertical resolution has been developed. This instrument uses an optical method based on observation of the moon
limb with a DIMM configuration (Differential Image Motion Monitor). Indeed, in the PBL the lunar limb is observed
through two sub-apertures of 6cm separated by a base of 30cm. The moon limb offers a continuum of
stars at different angular separations allowing the scan the atmosphere with a very high resolution. The angular
correlation along the lunar limb between of the differential distance between the two images of the lunar edge
leads to the C2n(h) profile. The other parameters of turbulence are also accessible from this instrument as the
profile of outer scale, the seeing and isoplanatic and isopistonic domains. The PBL succeeded to our first moon limb
profiler MOSP (Monitor of Outer Scale Profile) which was developed mainly for outer scale profile extraction.
Several campaigns have been carried out with MOSP particularly at Mauna Kea Observatory (Hawaii) and Cerro
Paranal in Chile. The PBL instrument has been installed at Dome C in Antarctica since January 2011. In addition
to this winterized PBL for Dome C, a second copy of this instrument has been developed for mid-latitude sites.
A first campaign with this light version of PBL, was carried out at the South African Large Telescope (SALT)
Observatory in August 2011.
Mapping interorganisational collaboration within biomedicine : collaboration in infection and immunity research
Creators: name: Lander, Bryn
Publisher: name: University of British Columbia
Year: 2014

description: Background: Collaborations between and within sectors facilitate research and development by transferring knowledge among individuals; but it is often unclear who is involved, with whom they are collaborating, and why they are collaborating. I studied the collaborations of Vancouver-based infection and immunity researchers both with local and non-local collaborators, combining innovation systems with economic geography, neo-institutional theory, Bourdieu’s concept of fields, and a social network perspective. My objectives were to determine how different types of proximity affect collaboration, investigate what motivates collaboration, and to explore how institutions affect collaboration. Methods: I used a mixed methods approach that drew on infection and immunity co-authorships, interviews with infection and immunity researchers, and policy documents. I quantitatively analysed co-authorship trends to explore the impact of institutional and geographic proximity on global co-authorship patterns of Vancouver-based infection and immunity researchers through sociograms, proximity variables, and a quasi-Poisson random effects regression. I investigated collaboration rates between and within sectors through relational contingency table and ANOVA network analysis. I mapped the major organisations and regulative institutions involved in Vancouver’s local infection and immunity network by combining interviews, policy documents, and co-authorship data. Based on interviews, I examined how sectoral and organisational institutions and capital influenced action. Results: I found that Vancouver’s infection and immunity network was dominated by the non-commercial sector, particularly universities. The private sector presence was weak. Geographic and institutional proximity increased the proclivity to co-author papers. Hospitals and universities co-authored more papers together than statistically expected. Vancouver-based infection and immunity researchers collaborated to gain capital to further goals, a process shaped by institutions. Conclusion: This study has important implications for science and innovation theory as well as science policy. For both, my primary contribution is to further the understanding that interactions between non-commercial actors play in knowledge translation and innovation, a role that is often underemphasized in both theory and policy.
