Collaborative development of medical devices : qualitative study of communication between physicians and engineers
Creators: name: Aida, Hassani
Publisher: name: University of British Columbia
Year: 2019

description: The importance of collaboration between physicians and engineers on improving the medical devices and patient safety is highly recognized. Previous studies found communication as an important component to interdisciplinary collaboration, however, maintaining an effective interdisciplinary communication can be challenging. With scarce literature on investigating the interaction between physicians and engineers, this study focuses on exploring the communication experiences of these two professional groups who have worked together collaboratively on medical devices. To better understand their challenges and facilitators, this research identifies six pairs of engineers and physicians who have worked together for years. All six cases, twelve engineers and physicians in total, are interviewed separately under qualitative case study method. The result of thematic analysis discovers three main categories: building relationship, team members quality, and communication techniques. The findings show that team members quality such as interest and dedication can help build strong relationships. Defining clear expectations at the beginning of the projects as well as sharing workload seem to improve relationships and foster communication. Other techniques contributing to effective communication include continuous feedback and face to face meetings. With a more careful analysis of findings, a model of personal and contextual factors with an emphasis on their interrelationship is suggested. Reviewing communication practices in all six cases illustrates that the benefits of collaboration overweigh the barriers. Thus, it is recommended that collaboration between physicians and engineers continue in the whole process of developing medical devices.

description: Attempts to achieve "top kill" of actively flowing oil wells by insertion of dense drilling "muds", i.e., slurries of dense minerals, from above will fail if the Kelvin-Helmholtz instability in the gravity-driven counterflow produces turbulence that breaks up the denser fluid into small droplets. Here we estimate the droplet size to be sub-mm for fast flows and suggest the addition of a shear-thickening polymer to suppress turbulence. Laboratory experiments show a progression from droplet formation to complete turbulence suppression at the relevant high velocities, illustrating rich new physics accessible by using a shear-thickening liquid in gravity driven counter-streaming flows.

Demarcating screen space : cosmopolitical technologies at vídeo nas aldeias
Creators: name: Shamash, Sarah
Publisher: name: University of British Columbia
Year: 2019

description: In this case study of the organization and film and video archive known as Vídeo nas Aldeias (Video in the Villages or VNA), founded in 1986 by Vincent Carelli, I develop an argument for VNA as a critical filmic archive worthy of study and safeguarding. Crucially, I examine VNA as a producer of knowledge through an interdisciplinary framework. Its collection comprises over ninety films on and by Indigenous peoples, representing over forty Indigenous nations across Brazil. As a practicing media artist and filmmaker, I apply an interdisciplinary framework to develop philosophical arguments and film analyses to conceptualizing VNA’s archive as a pluriversal and anti-colonial technology of knowledge. Over-arching concepts of visual sovereignty, as elaborated by Native American scholars Michelle H. Raheja (Seneca) and Jolene Rickard (Tuscarora Nation), as well as concepts by Laura R. Graham to include representational sovereignty, as theoretical frameworks with which to examine individual films and the archive as a whole, guide my analysis. I use Amalia Córdoba and Juan Salazar’s discussion of “imperfect media” to root my analysis in Latin American theory. I argue that the films are constituent of cosmopolitical processes that can be framed within onto-epistemic oriented cinema; I appraise how the films and the archive have repercussions on and off screen. A key objective of this dissertation is to broaden the field of film studies to include Indigenous cinema, not as an addendum to film studies, but as integral to film history and film culture. I conclude by examining how VNA, by means of its creation of a growing, alternative filmic corpus, is working to invigorate futures for Indigenous peoples and for cinema studies.
Book Groups in the Social Justice Unionism Movement
Creators: name: Riley, Kathleen
Publisher: name: Critical Education
Year: 2021

description: Abstract: The past decade has seen a rise in social justice teacher unionism, with an emergence of caucuses that focus on bottom-up, race conscious union reform focused on bargaining for the common good. While a burgeoning body of scholarship has focused on understanding the goals and interworkings of these caucuses, there are few up-close accounts of their political education efforts. This study focuses on an annual series of interconnected book groups and aims to understand teachers’ reasons for joining the groups and the role the groups play in the organization’s larger goals. Findings indicate that participants saw building the base, developing skills, deepening analyses, and planning action as four core functions of the groups. After analyzing subcategories within each finding, this article discusses tensions that arise in locating book groups within a political organization and implications for teachers, organizers, teacher educators, and researchers.

Improved Achievable Rates for Regularized Tomlinson-Harashima Precoding in Multiuser MIMO Downlink
Creators: name: Hui, Bing

Publisher: name: arXiv
Year: 2011
Subjects: subject: Information Theory (cs.IT)

description: Tomlinson-Harashima precoding (THP) is considered as a prominent precoding scheme due to its capability to efficiently cancel out the known interference at the transmitter side. Therefore, the information rates achieved by THP are superior to those achieved by conventional linear precoding schemes. In this paper, a new lower bound on the achievable information rate for the regularized THP scheme under additive white Gaussian noise (AWGN) channel with multiuser interference is derived. Analytical results show that the lower bound derived in this paper is tighter than the original lower bound particularly for a low SNR range, while all lower bounds converge to 0.5xlog2(6SNR/πe) as SNR approaches infinity.

description: Lenstra-Lenstra-Lovasz (LLL) algorithm, which is one of the lattice reduction (LR) techniques, has been extensively used to obtain better basis of the channel matrix. In this paper, we jointly apply Seysen's lattice reduction algorithm (SA), instead of LLL, with the conventional linear precoding algorithms. Since SA obtains more orthogonal lattice basis compared to that obtained by LLL, lattice reduction aided (LRA) precoding based on SA algorithm outperforms the LRA precoding with LLL. Simulation results demonstrate that a gain of 0.5dB at target BER of 10^-5 is achieved when SA is used instead of LLL for the LR stage.

description: Certain oscillatory features in the primordial scalar power spectrum are known to provide a better fit to the outliers in the cosmic microwave background data near the multipole moments of $\ell=22$ and 40. These features are usually generated by introducing a step in the popular, quadratic potential describing the canonical scalar field. Such a model will be ruled out, if the tensors remain undetected at a level corresponding to a tensor-to-scalar ratio of, say, $r\simeq 0.1$. In this work, in addition to the popular quadratic potential, we investigate the effects of the step in a small field model and a tachyon model. With possible applications to future datasets (such as PLANCK) in mind, we evaluate the tensor power spectrum exactly, and include its contribution in our analysis. We compare the models with the WMAP (five as well as seven-year), the QUaD and the ACBAR data. As expected, a step at a particular location and of a suitable magnitude and width is found to improve the fit to the outliers (near $\ell=22$ and 40) in all these cases. We point out that, if the tensors prove to be small (say, $r\lesssim 0.01$), the quadratic potential and the tachyon model will cease to be viable, and more attention will need to be paid to examples such as the small field models.

Publisher: name: Critical Education
Year: 2020

description: This special series offers the readers of Critical Education groundbreaking work by scholars who explore a myriad of issues related to how ableism manifests and is resisted in higher education. Ableism is defined as the idea that able-bodiedness/mindedness is a preferred way of being in society. In this series introduction we, the editors, recount our own orientations to the themes that are brought forth in the special issue. Subsequently, we synthesize the innovative themes that have emerged in the eight manuscripts that are a part of this special issue, including: 1) Asking: from whose perspective should we learn about disability experiences in higher education?; 2) Describing the critically-oriented theoretical perspective employed across the manuscripts, all of which align to a disability studies perspective; 3) Questioning who is invited to participate and thrive in the academy; and 4) Exploring tactics used to create change and breakdown ableist structures that persist in the academy. Ultimately, we feel the implications of the work undertaken by the authors in this special issue are far-reaching and encourage the increased citizenry of disabled people, elevate the social positioning of disabled people in higher education settings, and ultimately reframe what it means to be labeled as disabled.

Reconstructing ν̅ₑ energy spectrum and ground state branching fraction of laser trapped ⁹²Rb
Creators: name: McNeil, James Cameron
Publisher: name: University of British Columbia
Year: 2019

description: The anti-electron neutrino ν̅ₑ energy spectra from the fission product ⁹²Rb is of interest for reactor neutrino physics and short baseline neutrino oscillation experiments. A study of the beta-neutrino correlation parameter a₁ was performed in laser trapped neutral ⁹²Rb, constraining the strong ground-state to ground-state (GS) first-forbidden 0⁻→ 0⁺ rank-0 nuclear matrix element ratio ξₒ/ω. The first-forbidden rank-0 correlation parameter depends non-linearly on beta energy W with a₁(ξₒ,ω,W) for a decay end-point of Wₒ. Two distinct analysis were performed via: 1) recoils coincident with atomic shake-off electrons (SOE); and 2) recoils coincident with the beta and atomic SOE. In the former case-1, no distinction can be made between transitions to the GS or excited states and we find the two possible solutions (ξ̅/ω})ᴿ^Sᴼᴱ^^⁺_R_S_O_E_^₋ = ⁺⁰^.⁴³⁷₋₀_.₅₁₂ ± (⁰^.⁰⁰⁵₀_.₀₀₈)ₛₜₐₜ ± (⁰^.⁰¹₀_.₀₁)ₛ_yₛ$ with a₁(W → Wₒ) → ⁰^.³⁰₀_.₃₆, respectively. In the later case-2, however, GS events are isolated through kinematic constraints on the reconstructed transition $Qₑₓₚ-value, with two possible solutions being (ξ̅/ω})ᴮᴿ^Sᴼᴱ^^⁺_B_R_S_O_E_^₋ = ⁺⁰^.⁵⁴¹₋₀_.₇₃₉ ± (⁰^.⁰⁰⁸₀_.₀₁₈)ₛₜₐₜ ± (⁰^.⁰¹₀_.₀₁)ₛ_yₛ with a₁(W → Wₒ) → ⁰^.⁵⁰₀_.₅₈, respectively. These are all significantly different from the naively expected |ξₒ/ω| ≫ 1, and a₁(W → Wₒ) = 1. From the beta-recoil 3-momenta, the ν̅ₑ energy spectra was also reconstructed for decays through the GS, and eventually compared with theory. We also present our future proposal to measure the GS branching ratio from the reconstructed Qₑₓₚ-value distribution.

Lett. 95, 203001 (2005)], we determine the value of the fine-structure constant αwith an accuracy of 31 parts per billion.

description: The Squirrel Cage Induction Motor(SCIM) is a critical component of many industrial applications and has been over the years the subject of extensive study. Much work has been done on condition monitoring and fault diagnostics, with the objective of reducing uncertainty of operation and thereby preventing costly downtime. However the performance of current monitoring and fault diagnostic strategies warrant the need for a more robust and reliable condition monitoring system. This thesis outlines the work done on the related fields of Data Acquisition and Fault Diagnostics with regard to providing a more efficient and robust condition monitoring system for an Industrial Three Phase SCIM. The Automated Remote Data Acquisition and Signal Analysis architecture implementation involved building a hardware unit to acquire the currents and voltages from the three phases of the SCIM. The Data Acquisition (DAQ) was controlled by a software architecture that has extensive features built into it for automation, remote access, file transfer, data archival, error monitoring and signal analysis. Acquisition parameters can be configured dynamically and results of analysis can be viewed through remote access to a server location. Proper security measures have also been incorporated into the architecture. In the area of fault diagnostics, the thesis provides a comprehensive review of the common faults in SCIM’s, their causes and effects, and existing diagnostic technologies. A theoretical overview and implementation details with regard to the traditional signal-based fault diagnostic approach of Motor Current Signature Analysis (MCSA) is also presented. Focus has been applied on the use of analytical redundancy concepts for model-based fault diagnostics using banks of nonlinear observers for the detection, identification and severity assessment of the major faults occurring in three phase squirrel cage induction motors. Residual generation was done using Extended Kalman Filter (EKF) observers developed for healthy and faulty operating conditions. A comparative study is done against the traditional signal-based current signature analysis method under ideal and nonideal conditions including power supply distortions. Theoretical details and simulation results are presented. The current scope, limitations and future work being undertaken in this area are also outlined

description: Elastic sheets with macroscopic dimensions are easy to deform by bending and stretching. Yet shaping nanometric sheets by mechanical manipulation is hard. Here we show that nanoparticle self-assembly could be used to this end. We demonstrate by Monte Carlo simulation that spherical nanoparticles adhering to the outer surface of an elastic nanotube can self-assemble into linear structures as a result of curvature-mediated interactions. We find that nanoparticles arrange into rings or helices on stretchable nanotubes, and as axial strings on nanotubes with high rigidity to stretching. These self-assembled structures are inextricably linked to a variety of deformed nanotube profiles, which can be controlled by tuning the concentration of nanoparticles, the nanoparticle-nanotube diameter ratio and the elastic properties of the nanotube. Our results open the possibility of designing nanoparticle-laden tubular nanostructures with tailored shapes, for potential applications in materials science and nanomedicine.

description: We present recent progress in the calculation of the helium fine-structure splitting of the 2^3P_J states, based on the quantum electrodynamic theory. Apart from the complete evaluation of mα^7 and m^2/Mα^6 corrections, we have performed extensive tests by comparison with all experimental results for light helium-like ions and with the known large nuclear charge asymptotics of individual corrections. Our theoretical predictions are still limited by the unknown mα^8 term, which is conservatively estimated to be 1.7 kHz. However, comparison with the latest experimental result for the 2^3P_0 - 2^3P_2 transition [M. Smiciklas and T. Shiner, Phys. Rev. Lett. 105, 123001 (2010)] suggests that the higher-order contribution is in fact much smaller than the theoretical estimate. This means that the spectroscopic determination of αcan be significantly improved if another measurement of the 2^3P_0 - 2^3P_2 transition in helium-like Li^+ or Be^{2+} ion is performed.

Fundamentals of collisionless shocks for astrophysical application, 2. Relativistic shocks

description: We review recent progress on collisionless relativistic shocks. Kinetic instability theory is briefed including its predictions and limitations. The main focus is on numerical experiments in (i) pair and (ii) electron-nucleon plasmas. The main results are: (i) confirmation of shock evolution in non-magnetised relativistic plasma in 3D due to either the lepton-Weibel instability or the ion-Weibel instability; (ii) sensitive dependence on upstream magnetisation ; (iii) the sensitive dependence of particle dynamics on the upstream magnetic inclination angle $\thetabn$, where particles of $\thetabn>34^\circ$ cannot escape upstream, leading to the distinction between `sub-luminal' and `super-luminal' shocks; (iv) particles in ultra-relativistic shocks can hardly overturn the shock and escape to upstream; they may oscillate around the shock ramp for a long time, so to speak `surfing it' and thereby becoming accelerated by a kind of SDA; (v) these particles form a power law tail on the downstream distribution; their limitations are pointed out; (vi) recently developed methods permit the calculation of the radiation spectra emitted by the downstream high-energy particles; (vii) the Weibel-generated downstream magnetic fields form large amplitude vortices which could be advected by the downstream flow to large distances from the shock and possibly contribute to an extended strong field region; (viii) if cosmic rays are included, Bell-like modes can generate upstream magnetic turbulence at short and, by diffusive re-coupling, also long wavelengths in nearly parallel magnetic field shocks; (ix) advection of such large-amplitude waves should cause periodic reformation of the quasi-parallel shock and eject large amplitude magnetic field vortices downstream where they contribute to turbulence and to maintaining an extended region of large magnetic fields.

Nucleosynthesis-relevant conditions in neutrino-driven supernova outflows. II. The reverse shock in two-dimensional simulations

description: After the initiation of the explosion of core-collapse supernovae, neutrinos emitted from the nascent neutron star drive a supersonic baryonic outflow. This neutrino-driven wind interacts with the more slowly moving, earlier supernova ejecta forming a wind termination shock (or reverse shock), which changes the local wind conditions and their evolution. Important nucleosynthesis processes (alpha-process, charged-particle reactions, r-process, and vp-process) occur or might occur in this environment. The nucleosynthesis depends on the long-time evolution of density, temperature, and expansion velocity. Here we present two-dimensional hydrodynamical simulations with an approximate description of neutrino-transport effects, which for the first time follow the post-bounce accretion, onset of the explosion, wind formation, and the wind expansion through the collision with the preceding supernova ejecta. Our results demonstrate that the anisotropic ejecta distribution has a great impact on the position of the reverse shock, the wind profile, and the long-time evolution. This suggests that hydrodynamic instabilities after core bounce and the consequential asymmetries may have important effects on the nucleosynthesis-relevant conditions in the neutrino-heated baryonic mass flow from proto-neutron stars.

description: We investigate dynamics of a flat FRW cosmological model with a barotropic matter and a non-minimally coupled scalar field (both canonical and phantom). In our approach we do not assume any specific form of a potential function for the scalar field and we are looking for generic scenarios of evolution. We show that dynamics of universe can be reduced to a 3-dimensional dynamical system. We have found the set of fixed points and established their character. These critical points represent all important epochs in evolution of the universe : (a) a finite scale factor singularity, (b) an inflation (rapid-roll and slow-roll), (c) a radiation domination, (d) a matter domination and (e) a quintessence era. We have shown that the inflation, the radiation and matter domination epochs are transient ones and last for a finite amount of time. The existence of the radiation domination epoch is purely the effect of a non-minimal coupling constant. We show the existence of a twister type solution wandering between all these critical points.
