Towards redesigning legacy GFRP-constructed aquatic structures with flexible, durable, and recyclable alternative materials : a multicriteria approach
Creators: name: Liu, Haoyang
Publisher: name: University of British Columbia
Year: 2023

description: For structural components used in leisure industries, such as those in aquaparks, high load-bearing capacity and lightweight materials are of primary interest. For this purpose, rigid fibre reinforced polymer (FRP) composites are currently used widely. However, they often result in large and stiff moulded parts, which lead to logistic challenges as well as added cost associated with transportation and handling. FRP materials are also difficult to recycle, raising concerns over environmental sustainability. One proposed solution may be to replace such legacy materials with flexible, durable, and recyclable alternatives, while redesigning the support structures so that the overall integrity and load-bearing capacity remain unchanged. The high flexibility of the alternative materials can enable them to be rolled or folded (i.e., reduce occupied space) during transportation. Towards the above motivation, this thesis is a preliminary investigation towards replacing glass fibre reinforced polymer (GFRP) composites used in aquatic play structures with flexible, durable, and recyclable alternatives. Two thermoplastic polyurethanes (TPU) and one thermoplastic vulcanizate (TPV) were chosen as candidate materials. The physical and mechanical properties of the legacy (base) and candidate materials were characterized through a series of coupon-level experiments and imaging. Material samples were also subjected to weathering exposures, including water and chlorinated water immersion, hygrothermal aging, and accelerated weathering in xenon lamp chamber. GFRP exhibited superior tensile strength and modulus, while the TPE candidates showed higher flexibility and strain at break. TPU showed better abrasion and puncture resistance than the TPV candidate, but higher water absorption. Yellowing could be observed for TPU after weathering in xenon lamp chamber. No statistically significant changes in the tensile properties could be concluded for all materials upon weathering. Next, building on the above characterization test data, a multicriteria decision making method, namely PROMETHEE II, was implemented to evaluate and rank the legacy and candidate materials based on typical design criteria including cost, mechanical properties, weathering performance, and recyclability. Texin 285A (TPU) was ranked as the top choice. Design ideas to incorporate the flexible material into water slide flumes, including a honeycomb sandwich structure design and a diaphragm design, were also explored.

description: In this work we investigate a Schwarzschild-type black hole that is corrected by the Generalized Uncertainty Principle (GUP) and possesses topological defects within the framework of Bumblebee gravity. Our focus is on the thermodynamic characteristics of the black hole, such as temperature, entropy and heat capacity, which vary as functions of the horizon radius, and also on shadow as an optical feature. Our investigation reveals significant changes in the thermodynamic behavior of the black hole due to violations of Lorentz symmetry, GUP corrections, and the presence of monopoles. However, the shadow of the black hole is unaffected by violations of Lorentz symmetry. In addition, we provide a limit on the parameters of Lorentz symmetry violation, GUP and topological defects based on a classical test involving the precession of planetary orbits and the advancement of perihelion in the solar system.

description: In situ chemical oxidation using permanganate as an oxidant is a remediation technique often used to treat contaminated groundwater. In this paper, groundwater flow with a full hydraulic conductivity tensor and remediation process through in situ chemical oxidation are simulated. The numerical approach was verified with a physical sandbox experiment and analytical solution for 2D advection-diffusion with a first-order decay rate constant. The numerical results were in good agreement with the results of physical sandbox model and the analytical solution. The developed model was applied to two different studies, using multi-objective genetic algorithm to optimise remediation design. In order to reach the optimised design, three objectives considering three constraints were defined. The time to reach the desired concentration and remediation cost regarding the number of required oxidant sources in the optimised design was less than any arbitrary design.

The Jacquet-Langlands correspondence provides a bijection between smooth irreducible representations of $B^\times$ of dimension $>1$ and irreducible cuspidal representations of $GL_2(F)$. We present a new construction of this bijection in which the preservation of epsilon factors is automatic.

Utilizing Type Ia Supernovae in a Large, Fast, Imaging Survey to Constrain Dark Energy

description: We study the utility of a large sample of type Ia supernovae that might be observed in an imaging survey that rapidly scans a large fraction of the sky for constraining dark energy. We consider information from the traditional luminosity distance test as well as the spread in SNeIa fluxes at fixed redshift induced by gravitational lensing. We include a treatment of photometric redshift uncertainties in our analysis. Our primary result is that the information contained in the mean distance moduli of SNeIa and the dispersion among SNeIa distance moduli complement each other, breaking a degeneracy between the present dark energy equation of state and its time variation without the need for a high-redshift supernova sample. To address photometric redshift uncertainties, we present dark energy constraints as a function of the size of an external set of spectroscopically-observed SNeIa that may be used for redshift calibration, nspec. We find that an imaging survey can constrain the dark energy equation of state at the epoch where it is best constrained with a 1-sigma error of sigma(wpiv)~0.03-0.09$, depending upon various assumptions. In addition, the marginal improvement in the error sigma(wpiv) from an increase in the spectroscopic calibration sample drops once nspec ~ 10^3. This result is important because it is of the order of the size of calibration samples likely to be compiled in the coming decade and because, for samples of this size, the spectroscopic and imaging surveys individually place comparable constraints on the dark energy equation of state. In all cases, it is best to calibrate photometric redshifts with a set of spectroscopically-observed SNeIa with relatively more objects at high redshift than the parent sample of imaging SNeIa.

description: In the core accretion model, planetesimals grow by mutual collisions and engulfing millimeter-to-centimeter particles, i.e., pebbles. Pebble accretion can significantly increase the accretion efficiency and help explain the presence of planets on wide orbits. However, the pebble supply is typically parameterized as a coherent pebble mass flux, sometimes being constant in space and time. Here we solve the dust advection and diffusion within viciously evolving protoplanetary disks to determine the pebble supply self-consistently. The pebbles are then accreted by planetesimals interacting with the gas disk via gas drag and gravitational torque. The pebble supply is variable with space and decays with time quickly, with a pebble flux below 10 $M_\oplus$ Myr$^{-1}$ after 1 Myr in our models. As a result, only when massive planetesimals ($>$ 0.01 $M_\oplus$) are luckily produced by the streaming instability or the disk has low viscosity ($α\sim 0.0001$) can the herd of planetesimals grow over a Mars mass within 2 Myr. By then, planetesimals only capture pebbles about 50 times their mass and as little as 10 times beyond 20 au due to limited pebble supply. Further studies considering multiple dust species in various disk conditions are warranted to fully assess the realistic pebble supply and its influence on planetesimal growth.

description: With the appearance and improvement of Web 2.0 technology and other digital tools such as Google Docs and wikis, teachers and researchers are increasingly able to implement collaborative activities in face-to-face and online language courses. Whether technologically assisted or done in person, collaboration is a burgeoning area of investigation in L2 writing research and practice. Although many researchers and teachers alike still consider writing an independent activity, Collaborative Writing in L2 Classrooms has taken the charge to illuminate the potential advantages of employing collaborative writing in language research and by extension pedagogical practice. To do so, Storch offers a comprehensive review of the current research on L2 collaborative writing, while identifying that there remains theoretical uncertainty concerning how writing tasks affect the product and process of collaborative writing across and within learner contexts, and how the formation of collaborative pairs and groups may change the nature of the collaborative writing project.

description: A two-spin-1/2 Heisenberg XYZ model with Dzyaloshinsky--Moriya (DM) and Kaplan--Shekhtman--Entin-Wohlman--Aharony (KSEA) interactions in the presence of an inhomogeneous external magnetic field is considered at thermal equilibrium. Its density matrix has the general X form for which we derive explicit formulas for the local quantum Fisher information (LQFI) and local quantum uncertainty (LQU) directly in terms of model parameters. This allows us to perform a comparative study for the discord-type quantum correlations LQFI and LQU and to reveal a number of new features in their behavior. In particular, the sudden transitions of quantum correlations with a smooth change in temperature are found. Moreover, it is shown that there may be a sequence of such transitions for certain choices of interaction constants.

description: Forthcoming astronomical imaging surveys will use weak gravitational lensing shear as a primary probe to study dark energy, with accuracy requirements at the 0.1% level. We present an implementation of the Metadetection shear measurement algorithm for use with the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). This new code works with the data products produced by the LSST Science Pipelines, and uses the pipeline algorithms when possible. We tested the code using a new set of simulations designed to mimic LSST imaging data. The simulated images contained semi-realistic galaxies, stars with representative distributions of magnitudes and galactic spatial density, cosmic rays, bad CCD columns and spatially variable point spread functions. Bright stars were saturated and simulated ``bleed trails'' were drawn. Problem areas were interpolated, and the images were coadded into small cells, excluding images not fully covering the cell to guarantee a continuous point spread function. In all our tests the measured shear was accurate within the LSST requirements.

Using biosolids to mitigate drought effects in a semi-arid grassland with and without grazing by cattle
Creators: name: Planz, Nikita
Publisher: name: University of British Columbia
Year: 2023

description: Climate extremes are becoming more common throughout semi-arid rangelands of British Columbia; therefore, finding climate mitigation techniques is paramount. Biosolids are a soil amendment made from treated municipal wastewater that can be surface applied to grasslands to aid in reclamation and increase primary productivity. The purpose of this work was to examine the ability of a single application of biosolids to mitigate drought effects in a semi-arid, grazed and ungrazed, grassland 19 years after application. In 2002, biosolids were applied at a rate of 20 Mg ha-1 in two study sites, then one of these sites was fenced to create a grazing exclosure. In 2020 rainout shelters were constructed to simulate a growing season drought for approximately two years, where the experimental drought plots had a median 55% reduction in soil moisture. Before and after sampling included above and belowground biomass as well as plant community composition. Further, soil bulk density, pH, organic matter, total carbon and nitrogen, and soil water content were analysed. Rainout shelters reduced root biomass but the biosolids treatment mitigated this loss. Additionally, biosolids significantly increased aboveground biomass and litter. Biosolids lowered diversity, whereas open grazing increased diversity. Biosolids also increased total carbon, total nitrogen, and soil organic matter. The only soil metric altered by the experimental drought treatment was soil water content, which was lowered. Overall, a single application of biosolids had positive lasting effects on the ecosystem nearly two decades later. Although some undesirable outcomes were observed, grazing may be used as a management tool, in combination with biosolids, to meet reclamation targets in a semi-arid rangeland. Further research is needed to understand the relationship between drought, biosolids, and grazing in semi-arid grasslands in British Columbia.

description: Germany has become one of the leading players in the transformation of the electricity sector, now having up to 42% of electricity coming from renewable sources. However, the transformation of the heating sector is still in its infancy, and especially the provision of industrial process heating is highly dependent on unsustainable fuels. One of the most promising heating technologies for renewable energies is power-to-heat, especially heat pump technology, as it can use renewable electricity to generate heat efficiently. This research explores the economic and technical boundary conditions regarding the integration of heat pumps into existing industrial thermohydraulic heating and cooling networks. To calculate the optimum design and control of heat pumps, a mixed-integer linear programming model (MILP) is developed. The model seeks the most cost-efficient configuration of heat pumps and stratified thermal storage tanks. Additionally, it optimizes the operation of all energy converters and stratified thermal storage tanks to meet a specified heating and cooling demand over one year. The objective function is modeled after the net present value (NPV) method and considers capital expenditures (costs for heat pumps and stratified thermal storage tanks) and operational expenditures (electricity costs and costs for conventional heating and cooling). The comparison of the results via a simulation model reveals an accuracy of more than 90%.

description: Computing strongly connected components (SCC) is a fundamental problems in graph processing. As today's real-world graphs are getting larger and larger, parallel SCC is increasingly important. SCC is challenging in the parallel setting and is particularly hard on large-diameter graphs. Many existing parallel SCC implementations can be even slower than Tarjan's sequential algorithm on large-diameter graphs. To tackle this challenge, we propose an efficient parallel SCC implementation using a new parallel reachability algorithm. Our solution is based on a novel idea referred to as vertical granularity control (VGC). It breaks the synchronization barriers to increase parallelism and hide scheduling overhead. To use VGC in our SCC algorithm, we also design an efficient data structure called the \emph{parallel hash bag}. It uses parallel dynamic resizing to avoid redundant work in maintaining frontiers (vertices processed in a round). We implement the parallel SCC algorithm by Blelloch et al.\ (J.\ ACM, 2020) using our new parallel reachability algorithm. We compare our implementation to the state-of-the-art systems, including GBBS, iSpan, Multi-step, and our highly optimized Tarjan's (sequential) algorithm, on 18 graphs, including social, web, $k$-NN, and lattice graphs. On a machine with 96 cores, our implementation is the fastest on 16 out of 18 graphs. On average (geometric means) over all graphs, our SCC is 6.0$\times$ faster than the best previous parallel code (GBBS), 12.8$\times$ faster than Tarjan's sequential algorithms, and 2.7$\times$ faster than the \emph{best existing implementation on each graph}. We believe that our techniques are of independent interest. We also apply our parallel hash bag and VGC scheme to other graph problems, including connectivity and least-element lists (LE-lists).

description: Smartphones have become an essential part of our lives. Especially its computing power and its current specifications make a modern smartphone a powerful device for human activity recognition tasks. Equipped with various integrated sensors, a modern smartphone can be leveraged for lots of smart applications. We already investigated the possibility of using an unmodified commercial smartphone to recognize eight strength-based exercises. App-based workouts have become popular in the last few years. The advantage of using a mobile device is that you can practice anywhere at anytime. In our previous work, we proved the possibility of turning a commercial smartphone into an active sonar device to leverage the echo reflected from exercising movement close to the device. By conducting a test study with 14 participants, we showed the first results for cross person evaluation and the generalization ability of our inference models on disjoint participants. In this work, we extended another model to further improve the model generalizability and provided a thorough comparison of our proposed system to other existing state-of-the-art approaches. Finally, a concept of counting the repetitions is also provided in this study as a parallel task to classification.
On Hydrodynamic Motions in Dead Zones

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: We investigate fluid motions near the midplane of vertically stratified accretion disks with highly resistive midplanes. In such disks, the magnetorotational instability drives turbulence in thin layers surrounding a resistive, stable dead zone. The turbulent layers in turn drive motions in the dead zone. We examine the properties of these motions using three-dimensional, stratified, local, shearing-box, non-ideal, magnetohydrodynamical simulations. Although the turbulence in the active zones provides a source of vorticity to the midplane, no evidence for coherent vortices is found in our simulations. It appears that this is because of strong vertical oscillations in the dead zone. By analyzing time series of azimuthally-averaged flow quantities, we identify an axisymmetric wave mode particular to models with dead zones. This mode is reduced in amplitude, but not suppressed entirely, by changing the equation of state from isothermal to ideal. These waves are too low-frequency to affect sedimentation of dust to the midplane, but may have significance for the gravitational stability of the resulting midplane dust layers.

description: Over the course of six months, edTPA went from being an abstract jumble of letters thrown around to describe some assessment that we were going to have to do at some point before graduation (yes, the conversations were that uncertain) to a very concrete mountain that each member of my cohort was expected to climb triumphantly, in spite of the fact that the road to the top was still in the process of being built. In the beginning, I tried to pretend it didn't exist, in the middle I found myself grappling with how to best fit into a model that didn't seem to appreciate who I was as a teacher, and in the end I accepted that I had to jump through the hoop of fire at the end of the road if I wanted the medal of state certification hung round my neck. In psychology, they'd say I went through the five stages of grief and loss---denial, anger, bargaining, depression, and acceptance. Now how's that for a resounding endorsement for edTPA?

description: Context is an important factor in computer vision as it offers valuable information to clarify and analyze visual data. Utilizing the contextual information inherent in an image or a video can improve the precision and effectiveness of object detectors. For example, where recognizing an isolated object might be challenging, context information can improve comprehension of the scene. This study explores the impact of various context-based approaches to object detection. Initially, we investigate the role of context in object detection and survey it from several perspectives. We then review and discuss the most recent context-based object detection approaches and compare them. Finally, we conclude by addressing research questions and identifying gaps for further studies. More than 265 publications are included in this survey, covering different aspects of context in different categories of object detection, including general object detection, video object detection, small object detection, camouflaged object detection, zero-shot, one-shot, and few-shot object detection. This literature review presents a comprehensive overview of the latest advancements in context-based object detection, providing valuable contributions such as a thorough understanding of contextual information and effective methods for integrating various context types into object detection, thus benefiting researchers.

A text-to-world connection! I thought to myself, “If this idea doesn't persuade edTPA that I am worthy of being a teacher, then I don't know what they want.” Then again, at the time, none of us knew (or know now) what edTPA wants from us. Despite the endless depths of knowledge questions we bombarded our professors with, who did their best to negotiate the meaning of the new and vague edTPA, there was no way to prepare for the unit I was about to design. I saw the news. I made the connection. I immediately began planning for the next day’s lesson.

The applicability of the schemes is tested numerically using the fluctuation-exchange approximation as a cluster solver for the Hubbard model. Thermodynamic properties are found to be practically indistinguishable from those computed using the full self-consistent scheme in all cases where the non-interacting partial density of states is replaced by simplified analytic forms with matching 1st and 2nd moments. Green functions are also compared and found to be in close agreement, and the density of states computed using Padé approximant analytic continuation shows that dynamical properties can also be approximated effectively. Extensions to two-particle properties and multiple bands are discussed. Simplified approaches to the dynamical cluster approximation should lead to new analytic solutions of the Hubbard and other models.

description: Implemented as a high-stakes Teacher Performance Assessment, in my opinion, edTPA holds great promise for evaluating novice teachers’ readiness. However, in its current stage, this pre-service assessment is better in theory than practice. I do not want this paper to evolve into a ranting diatribe against edTPA, rather, I hope my insight will shed some light on how we can collectively move forward with sound strategies that best support our teachers and students in the field we all love: education.

description: We are stalwart advocates of public school education, and not just because we hold dear the notion of all citizens having access to the body of knowledge and critical thinking skills that they will use for the rest of their lives. We support it because we love it. There is nothing quite like walking through the doors of a bustling public school, and immediately being hit with the slightly musty smell of aging linoleum floors, seeing the sometimes crumbling but often lovingly decorated walls, and hearing what sounds like the chaotic noises of the students. When we step closer, however, we usually hear and see something that isn't so much chaotic, but rather, remarkable: growth-in-action. We see children-- younger or older-- who represent a plethora of cultures, speak many languages, and come from all walks of life. Within earshot or line of vision of these children, we see someone else, too. We see someone who cares deeply about learning, someone who has probably spent hours upon hours drawing up lesson plans and grading papers, and most importantly, someone who sincerely cares about these children, and thinks and worries about them far beyond the confines of the classroom.

description: The combination of magnetic and semiconducting properties in one material system has great potential for integration of emerging spintronics with conventional semiconductor technology. One standard route for the synthesis of magnetic semiconductors is doping of semiconductors with magnetic atoms. In many semiconductor–magnetic–dopant systems, the magnetic atoms form precipitates within the semiconducting matrix. An alternative and controlled way to realize such nanocomposite materials is the assembly by co-deposition of size-selected cluster ions and a semiconductor. Here we follow the latter approach to demonstrate that this fabrication route can be used to independently study the influence of cluster concentration and cluster size on magneto-transport properties. In this case we study Fe clusters composed of approximately 500 or 1000 atoms soft-landed into a thermally evaporated amorphous Ge matrix. The analysis of field and temperature dependent transport shows that tunneling processes affected by Coulomb blockade dominate at low temperatures. The nanocomposites show saturating tunneling magnetoresistance, additionally superimposed by at least one other effect not saturating upon the maximum applied field of 6 T. The nanocomposites’ resistivity and the observed tunneling magnetoresistance depend exponentially on the average distance between cluster surfaces. On the contrary, there is no notable influence of the cluster size on the tunneling magnetoresistance.
Strategic Competence and L2 Speaking Assessment

description: Assessing second language speaking has long been an important part of language testing in both large-scale assessment settings and in smaller scale classroom-based assessments. Accordingly, researchers in the second language (L2) assessment field have made efforts to establish a better understanding of the nature of speaking ability and its underlying competences. With speaking tests increasingly involving test takers' performances on certain tasks, test takers are required to utilize their language knowledge by means of their strategic competence (i.e., skills necessary to put language knowledge into use), which has been considered an integral component of communicative language ability (e.g., Bachman & Palmer, 1996) and L2 speaking ability (e.g., Bygate, 1987; Fulcher, 2003). However, what strategic competence in speaking entails remains unclear, as its definition has varied greatly across different theoretical models and empirical studies. This paper provides a brief overview of the varying approaches to defining strategic competence, and reports on major empirical findings related to the conceptualization of this important facet of speaking ability, surveying the extensive literature in the broader fields of applied linguistics and L2 assessment in particular.

description: Mixture-of-Experts (MoE) is a neural network architecture that adds sparsely activated expert blocks to a base model, increasing the number of parameters without impacting computational costs. However, current distributed deep learning frameworks are limited in their ability to train high-quality MoE models with large base models. In this work, we present DeepSpeed-TED, a novel, three-dimensional, hybrid parallel algorithm that combines data, tensor, and expert parallelism to enable the training of MoE models with 4 to 8x larger base models than the current state-of-the-art. We also describe memory optimizations in the optimizer step, and communication optimizations that eliminate unnecessary data movement. We implement our approach in DeepSpeed and achieve speedups of 26% over a baseline (i.e. without our communication optimizations) when training a 40 billion parameter MoE model (6.7 billion base model with 16 experts) on 128 V100 GPUs.

description: Noisy distance estimates associated with photometric rather than spectroscopic redshifts lead to a mis-estimate of the luminosities, and produce a correlated mis-estimate of the sizes. We consider a sample of early-type galaxies from the SDSS DR6 for which both spectroscopic and photometric information is available, and apply the generalization of the V_max method to correct for these biases. We show that our technique recovers the true redshift, magnitude and size distributions, as well as the true size-luminosity relation. We find that using only 10% of the spectroscopic information randomly spaced in our catalog is sufficient for the reconstructions to be accurate within about 3%, when the photometric redshift error is dz = 0.038. We then address the problem of extending our method to deep redshift catalogs, where only photometric information is available. In addition to the specific applications outlined here, our technique impacts a broader range of studies, when at least one distance-dependent quantity is involved. It is particularly relevant for the next generation of surveys, some of which will only have photometric information.

description: We introduce a new class of jet algorithms designed to return conical jets with a variable Delta R radius. A specific example, in which Delta R scales as 1/pT, proves particularly useful in capturing the kinematic features of a wide variety of hard scattering processes. We implement this Delta R scaling in a sequential recombination algorithm and test it by reconstructing resonance masses and kinematic endpoints. These test cases show 10-20% improvements in signal efficiency compared to fixed Delta R algorithms. We also comment on cuts useful in reducing continuum jet backgrounds.

description: The NASA Kepler mission is designed to find planets through transits. Accurate and precise radii of the detected planets depend on knowing the radius of the host star accurately, which is difficult unless the temperature and luminosity of the star are known precisely. Kepler, however, has an asteroseismology programme that will provide seismic variables that can characterise stellar radii easily, accurately, and extremely precisely. In this paper we describe the Yale-Birmingham (YB) method to determine stellar radii using a combination of seismic and conventional variables, and analyse the effect of these variables on the result. We find that for main-sequence stars, a knowledge of the parallax is not important to get accurate radii using the YB method: we can get results to an accuracy and precision of better than a few percent if we know the effective temperature and the seismic parameters for these stars. Metallicity does not make much difference either. However, good estimates of the effective temperature and metallicity, along with those of the seismic parameters, are essential to determine radii of sub giants properly. On the other hand, for red giants we find that determining radii properly is not possible without a good estimate of the parallax. We find that the so called "surface term" in the seismic data has minimal effect on the inferred radii. Uncertainties in the convective mixing length can matter under some circumstances and can cause a systematic shift in the inferred radii. Blind tests with data simulated to match those expected from the asteroseismic Survey Phase of Kepler show that it will be possible to infer stellar radii successfully using our method.
