Model-based spindle health monitoring
Creators: name: Tai, Chung-Yu
Publisher: name: University of British Columbia
Year: 2024

description: Spindle health monitoring in machine tools is paramount for optimizing performance and preventing costly downtimes due to repairs. The spindle, a critical component influencing machine tool efficiency, undergoes gradual wear and crack development, often stemming from long-term usage or serious collisions, especially in joint locations like bearing balls, raceways, and the tool holder taper contact interface. These faults result in significant vibrations and poor surface finish during machining operations. This thesis proposes a hybrid approach by integrating a physics-based digital model of the spindle with machine learning principles to enhance spindle health monitoring. Bearing faults, worn tool holder taper contact interfaces, and spindle imbalance are mathematically modeled and integrated into a dynamic digital model of spindles. These faults induce changes in preload and dynamic stiffness, leading to observable vibrations at the spindle speeds and ball passing frequencies. The digital spindle model predicts vibrations caused by spindle faults at specific measurement locations An analysis of multiple spindle fault couplings is implemented to recognize critical signal features used for training. Vibration spectra, natural frequencies, and dynamic stiffness changes are correlated to faults, experimentally validated before and after repair of spindles, as well as under different health conditions of tool holders. To monitor the spindle health, gate recurrent unit (GRU) neural network algorithms are employed for spindle fault detection and examination of its acceptable status. Pre-trained on vibration spectra generated by the physics-based spindle simulation model and fine-tuned by a few measurements, the GRU classifiers for addressing the fault locations and predictors for determining the acceptable levels achieve an accuracy of 96.74% and 94.10% on experimental datasets not used in training. The proposed integrated approach combines physics-based modeling and data-driven techniques, contributing to optimal spindle fault diagnosis performance, minimizing downtimes, and adhering to ISO standards for spindle status evaluation. All proposed methodologies are experimentally validated, offering a promising solution for enhancing the reliability and efficiency of spindle health monitoring systems in the manufacturing industry.

description: Il saggio ripercorre i miti di fondazione della città di Las Vegas; nata in seno agli ambienti dello spettacolo hollywoodiano. Si propone innanzitutto una riflessione sulla storia della città; emersa nel deserto in pieno Novecento; di cui vengono affrontati alcuni aspetti architettonici e urbanistici; ma anche l’afflusso di capitali di provenienza incerta ma geograficamente collocati a Los Angeles che ne hanno permesso l’edificazione. Si procede poi a raccontare l’intreccio indissolubile fra gli ambienti dello spettacolo fra lo stato della California e quello del Nevada; con particolare attenzione al pendolarismo di artisti quali Elvis Presley; Bing Crosby e il Rat Pack; ma anche di gangster come Bugsy Malone. In un movimento opposto; il saggio affronta anche le ripercussioni dell’estetica di Las Vegas all’esterno; in particolare attraverso lo studio proposto dall’architetto Robert Venturi che in modo articolato ha rotto gli stereotipi sulla città del divertimento per individuarne i simbolismi striscianti negli spazi urbani più diversificati.

description: We have used oxygen ions irradiation to generate controlled structural disorder in thin manganite films. Conductive atomic force microscopy CAFM), transport and magnetic measurements were performed to analyze the influence of the implantation process in the physical properties of the films. CAFM images show regions with different conductivity values, probably due to the random distribution of point defect or inhomogeneous changes of the local Mn3+/4+ ratio to reduce lattice strains of the irradiated areas. The transport and magnetic properties of these systems are interpreted in this context. Metal-insulator transition can be described in the frame of a percolative model. Disorder increases the distance between conducting regions, lowering the observed TMI. Point defect disorder increases localization of the carriers due to increased disorder and locally enhanced strain field. Remarkably, even with the inhomogeneous nature of the samples, no sign of low field magnetoresistance was found. Point defect disorder decreases the system magnetization but doesn t seem to change the magnetic transition temperature. As a consequence, an important decoupling between the magnetic and the metal-insulator transition is found for ion irradiated films as opposed to the classical double exchange model scenario.

Neoliberal equity, diversity, and inclusion? : a critical discourse analysis of the OECD's principles for inclusive curriculum
Creators: name: Hong, Seoyeon
Publisher: name: University of British Columbia
Year: 2024

description: In light of the globalizing trend of formal education, the research examines the Organisation for Economic Co-operation and Development’s (OECD) policy document titled Adapting Curriculum to Bridge Equity Gaps: Towards an Inclusive Curriculum (TIC). Although the OECD is an international organization, most of its global initiatives take place in the Western countries, focusing on the improvement of their socioeconomic welfare. The paper examines the OECD’s aspirations through its equity, diversity, and inclusion (EDI) education initiatives, and examines how it manages the conflicting principles of neoliberalism, neocolonialism, and inclusive education through the TIC policy. The thesis is developed on the methodology of Critical Discourse Analysis (CDA) and the analytical frameworks of Norman Fairclough and Michel Foucault. By examining the language, discourses, and structure of the TIC document, the research sheds light on the underlying assumptions and ideologies that inform the OECD's approach to EDI and examines how the document promotes neoliberal and neocolonial values. After a thorough textual analysis, this research concludes how the OECD’s advocacy for inclusive education achieves several goals: (1) equivocate discourse on EDI as inherently good, while targeting equity-deserving students for assimilation into Western education systems, (2) frame inclusive education to be beneficial not only for improved social justice but also for economic productivity, and (3) promote neoliberal coloniality and expresses the OECD’s aspiration to reinforce its position as an international organization and leader. The overarching goal of this thesis is to outline the underlying neoliberal and neocolonial implications of the OECD’s EDI policies.
A Spectroscopic Comparison of HED Meteorites and V-type Asteroids in the Inner Main Belt

description: V-type asteroids in the inner Main Belt (a < 2.5 AU) and the HED meteorites are thought to be genetically related to one another as collisional fragments from the surface of the large basaltic asteroid 4 Vesta. We investigate this relationship by comparing the near-infrared (0.7-2.5 micron) spectra of 39 V-type asteroids to laboratory spectra of HED meteorites. The central wavelengths and areas spanned by the 1 and 2 micron pyroxene-olivine absorption bands that are characteristic of planetary basalts are measured for both the asteroidal and meteoritic data. The band centers are shown to be well correlated, however the ratio of areas spanned by the 1 and 2 micron absorption bands are much larger for the asteroids than for the meteorites. We argue that this offset in band area ratio is consistent with our currently limited understanding of the effects of space weathering, however we can not rule out the possibility that this offset is due to compositional differences. Several other possible causes of this offset are discussed. Amongst these inner Main Belt asteroids we do not find evidence for non-Vestoid mineralogies. Instead, these asteroids seem to represent a continuum of compositions, consistent with an origin from a single differentiated parent body. In addition, our analysis shows that V-type asteroids with low inclinations (i < 6 degrees) tend to have band centers slightly shifted towards long wavelengths. This may imply that more than one collision on Vesta's surface was responsible for producing the observed population of inner belt V-type asteroids. Finally, we offer several predictions that can be tested when the Dawn spacecraft enters into orbit around Vesta in the summer of 2011.

Transferts de masse et de chaleur.

description: Les machines à absorption présentent de nombreux avantages pour les applications de production de froid à bas coût énergétique et environnemental. De nombreuses technologies de machines ont été mises au point, souvent basées sur un fluide de travail spécifique. Typiquement, ces fluides de travail sont des mélanges binaires de deux espèces dont l'enthalpie est dépendante du niveau de mélange de la solution. Cette dépendance se traduit par une réaction chimique exo ou endo-thermique lors de l'évaporation ou de la condensation du fluide, ce qui introduit un couplage très fort entre les transferts de masse et de chaleur. Les principaux fluides réfrigérants utilisés dans les machines à absorption sont l'ammoniac et l'eau. L'utilisation de solution saline comme fluide réfrigérant permet de s'affranchir d'un étage de rectification. Dans cette étude, deux machines distinctes fonctionnant avec deux mélanges binaires sont considérées. La première machine a pour fluide de travail \chemform{NH_3}-\chemform{Li N O_3} et pour la seconde ce fluide est \chemform{H_2O}-\chemform{Li Br}. Ces machines ont pour ambition d'utiliser des échangeurs à plaques standard afin de réduire leur coût de fabrication. Dans le cas du mélange à base d'ammoniac, les pressions de travail sont élevées (entre 3 et 6 bar), ce qui permet l'utilisation de générateur de vapeur noyés au niveau de l'évaporateur comme du désorbeur. Dans le cas des machines mettant en œuvre l'eau comme fluide frigorigène, les pressions de fonctionnement sont très faibles (entre 7 et 50 mbar), ce qui nécessite l'utilisation d'échangeurs à plaque couplés à des structures capillaires radiales spécifiques conçues pour limiter les pertes de charge. L'architecture des deux machines est comparée en fonction de leurs conditions de fonctionnement spécifiques sont comparées. L'évolution des performances des composants des machines est étudiée à l'aide de leurs efficacités. La modélisation qui en résulte est validée expérimentalement et les performances des machines sont évaluées aussi bien numériquement qu'expérimentalement.

description: La mise en forme de certains matériaux composites nécessite des températures élevées. Les moules sont souvent refroidis par l'écoulement d'eau dans des canaux cylindriques percés dans le moule. Pour faire face au problème du changement d'état dans les canaux de refroidissement un nouveau concept de refroidissement « Smart Element of Cooling » (SEC) a été développé en collaboration entre l'IRT jules Verne et le laboratoire GEPEA de Nantes Université avec la thèse PERFORM soutenue en janvier 2021 par E. AGYEMAN. L'approche consiste à impacter la surface du canal de refroidissement par multi-jets d'eau combinés à un écoulement d'air transverse imposé dans l'espace annulaire entre le tube d'eau central et la paroi interne du bloc. Dans cette étude, le refroidissement par jets impactants d'un bloc d'acier avec un écoulement multiphasique a été étudié expérimentalement. Le but est d'étudier les effets de différents paramètres hydrodynamiques et aérodynamiques sur les transferts thermiques au contact de la paroi interne du bloc. L'étude sera consacrée à l'influence du rapport des débits massiques et le nombre des jets sur la vitesse du refroidissement de la surface supérieure du bloc, l'homogénéité du refroidissement de cette dernière et les échanges thermique avec la paroi interne. Ces études nous permettront de mieux comprendre les phénomènes qui se produisent lorsque des jets d'eau sont soumis à un écoulement d'air dans un espace confiné cylindrique et les effets de l'interaction multi fluidiques sur les transferts thermiques entres les jets et la paroi. Les résultats obtenus montrent un effet significatif de ces paramètres sur la densité de flux thermique échangé et l'homogénéité du refroidissement. L'objectif de ces deux études est d'améliorer les performances de notre élément refroidisseur : notamment l'homogénéité du refroidissement de la surface supérieure qui sera en contact directe avec le matériau composite. Ce travail a permis aussi de valider l'utilité de ces paramètres permettant la meilleure régulation thermique de la surface de l'outillage

description: We discuss the possibility of generating noncritical quadrature squeezing by spontaneous polarization symmetry breaking. We consider first type-II frequency-degenerate optical parametric oscillators, but discard them for a number of reasons. Then we propose a four-wave mixing cavity in which the polarization of the output mode is always linear but has an arbitrary orientation. We show that in such a cavity complete noise suppression in a quadrature of the output field occurs, irrespective of the parameter values.

Improving robustness of deep learning models for processing ultrasound volumes for assessing developmental dysplasia of the hip
Creators: name: Hers, Benjamin
Publisher: name: University of British Columbia
Year: 2024

description: Developmental Dysplasia of the Hip (DDH) is a painful orthopaedic malformation diagnosed at birth in 1-3% of all newborns. Left untreated, DDH can lead to significant morbidity including long term disability. Currently the condition is clinically diagnosed using 2D ultrasound (US) imaging acquired between 0-6 months of age. DDH metrics are manually extracted by highly trained radiologists through manual measurements of relevant anatomy from the 2D US data, which remains a time consuming and highly error prone process. Recently, it was shown that combining 3D US imaging with deep learning (DL)-based automated diagnostic tools may significantly improve accuracy and reduce variability in measuring DDH metrics. However, robustness of current techniques remains insufficient for reliable deployment into real life clinical workflows. In this thesis, we present a quantitative robustness evaluation of state-of-the-art (SOTA) DL models in bone segmentation for 3D US and demonstrate examples of failed or implausible segmentations with SOTA models under common data variations, e.g., small changes in image resolution or anatomical field of view (FOV) from those encountered in the training data. We propose a 3D extension of the Seg- Former architecture, a lightweight transformer-based model with hierarchically structured encoders producing multi-scale features, which we show to concurrently improve accuracy and robustness. Specifically we show an increase in the 3% Dice score performance over the previous SOTA models for 3D US segmentation. To allow researchers, collaborators, clinicians, and doctors access to our DL models, we develop a prototype web-based application that will allow users to upload three dimensional US data and visualize their data before eventually selecting from various DL models to run on their data. The DL models will run in the background segmenting out the hip anatomical structures and return the calculated DDH metrics as well as relevant visualization of the segmentation and a 3D rendered mesh of the hip from the segmentation. We also investigate the use of learnable Gabor Filter Banks as a preprocessing layer in DL models to mimic the human visual system.
Symmetries and analytic properties of scattering amplitudes in N=4 SYM theory

description: In addition to the superconformal symmetry of the underlying Lagrangian, the scattering amplitudes in planar N=4 super-Yang-Mills theory exhibit a new, dual superconformal symmetry. We address the question of how powerful these symmetries are to completely determine the scattering amplitudes. We use the example of the NMHV superamplitudes to show that the combined action of conventional and dual superconformal symmetries is not sufficient to fix all the freedom in the tree-level amplitudes. We argue that the additional information needed comes from the study of the analytic properties of the amplitudes. The requirement of absence of spurious singularities, together with the correct multi-particle singular behavior, determines the unique linear combination of superinvariants corresponding to the n-particle NMHV superamplitude. The same result can be obtained recursively, by relating the n- and (n-1)-particle amplitudes in the singular collinear limit. We also formulate constraints on the loop corrections to the superamplitudes, following from the analytic behavior in the above limits. We then show that the holomorphic anomaly of the tree amplitudes leads to the breakdown of dual Poincare supersymmetry (which is equivalent to ordinary special conformal supersymmetry) of the ratio of the NMHV and MHV superamplitudes at one-loop level, but this anomaly does not affect dual conformal symmetry.

description: A minimal version of the inverse seesaw model featuring only two pairs of TeV-scale singlet neutrinos is discussed from the perspective of non-standard neutrino interactions. A particular attention is paid to the non-standard patterns of flavour and CP violation emerging due to the possibly enhanced non-decoupling effects of the heavy sector and the associated non-unitarity of the effective lepton mixing matrix.

description: We present a scheme for obtaining stable Casimir suspension of dielectric nontouching objects immersed in a fluid, validated here in various geometries consisting of ethanol-separated dielectric spheres and semi-infinite slabs. Stability is induced by the dispersion properties of real dielectric (monolithic) materials. A consequence of this effect is the possibility of stable configurations (clusters) of compact objects, which we illustrate via a "molecular" two-sphere dicluster geometry consiting of two bound spheres levitated above a gold slab. Our calculations also reveal a strong interplay between material and geometric dispersion, and this is exemplified by the qualitatively different stability behavior observed in planar versus spherical geometries.

description: Fire accidents in confined regions of public recreation theatres, malls, railroad cars and in tunnels are
influenced by atmospheric, confinement and fuel charge conditions. Obstacles in the confinements are
found to have a significant impact on flame propagation. Careful design of confinement geometry can
avoid accidents or slow down the flame propagation. Current experimental investigation is intended to
find the effect of obstacle interaction, free obstacle space, non-reacted gas flow, and turbulence at the
near-wall on flame acceleration. Two rows of bench shaped obstacles enhance the flame speed in the
obstacle free path. Turbulence intensity is higher in the local regions where flow is high subsonic and
mildly supersonic, which enhances the flame speed.

description: Evidence of magnetic interaction between late-type stars and close-in giant planets is provided by the observations of stellar hot spots rotating synchronously with the planets and showing an enhancement of chromospheric and X-ray fluxes. We investigate star-planet interaction in the framework of a magnetic field model of a stellar corona, considering the interaction between the coronal field and that of a planetary magnetosphere moving through the corona. The energy budget of the star-planet interaction is discussed assuming that the planet may trigger a release of the energy of the coronal field by decreasing its relative helicity. The observed intermittent character of the star-planet interaction is explained by a topological change of the stellar coronal field, induced by a variation of its relative helicity. The model predicts the formation of many prominence-like structures in the case of highly active stars owing to the accumulation of matter evaporated from the planet inside an azimuthal flux rope in the outer corona. Moreover, the model can explain why stars accompanied by close-in planets have a higher X-ray luminosity than those with distant planets. It predicts that the best conditions to detect radio emission from the exoplanets and their host stars are achieved when the field topology is characterized by field lines connected to the surface of the star, leading to a chromospheric hot spot rotating synchronously with the planet. The main predictions of the model can be verified with present observational techniques, by a simultaneous monitoring of the chromospheric flux and X-ray (or radio) emission, and spectropolarimetric observations of the photospheric magnetic fields.

Parallèlement, nous avons l'ambition de respecter l'Accord de Paris et réduire drastiquement nos émissions de gaz à effet de serre afin d'atteindre la neutralité carbone à l'horizon 2050. De plus, au-delà des engagements climatiques, les normes en matière d'émissions polluantes se renforcent dans les politiques sanitaires globales. Les ressources renouvelables produites à base de déchets que sont les syngaz sont de bons postulants à ces objectifs de diversification énergétique, particulièrement dans un contexte de production décentralisée telle que l'utilisation de micro turbines à gaz dans une application de cogénération de faible puissance. L'objectif de ce travail est d'identifier le comportement combustible de syngaz à haute teneur en vapeur d'eau dans une chambre de combustion industrielle, originellement conçue pour le gaz naturel, en variant la distribution de syngaz entre la flamme pilote et la flamme principale. Les résultats montrent le champ de vitesse et de température pour une gamme de distribution combustible pilote/principale ainsi que des prédictions précises sur le CO et les NOx. Il a été montré que les NOx sont particulièrement sensibles aux modifications de distribution de combustible et particulièrement à la richesse locale de la flamme pilote (augmentation de la fraction massique de syngaz dans la zone pilote pour une puissance thermique totale équivalente). La richesse importante dans la zone pilote favorise la stabilité de la flamme mais rencontre des effets négatifs en augmentant la production de NOx apparaissant dans les zones à très hautes températures Ces résultats obtenus pourront servir de références dans la caractérisation de gammes étendues de conditions de combustion diluées spécifiques aux syngaz ainsi que de plages de fonctionnement contrôlant la distribution de combustibles flamme pilote/principale vis-à-vis de la stabilité de combustion et des émissions de polluants. Ces spécifications sur une chambre de combustion permettront d'évaluer les points de fonctionnement optimaux pour un cycle complet d'application de cogénération, ce qui permettra d'exploiter entièrement leur potentiel pour des systèmes de faible puissance.

description: The capture of a moving atom by a non-dissipative trap, such as an optical dipole trap, requires the removal of the excessive kinetic energy of the atom. In this article we develop a mechanism to harvest ultra cold atoms from a guided atom beam into an optical dipole trap by removing their directed kinetic energy. We propose a continuous loading scheme where this is accomplished via deceleration by a magnetic potential barrier followed by optical pumping to the energetically lowest Zeeman sublevel. We theoretically investigate the application of this scheme to the transfer of ultra cold chromium atoms from a magnetically guided atom beam into a deep optical dipole trap. We discuss the realization of a suitable magnetic field configuration. Based on numerical simulations of the loading process we analyze the feasibility and efficiency of our loading scheme.

description: We extend the k_\perp-factorization formalism for exclusive photoproduction of vector mesons to the production of electroweak Z^0 bosons. Predictions for the gamma p \to Z^0 p and p p \to p p Z^0 reactions are given using an unintegrated gluon distribution tested against deep inelastic data. We present distributions in the Z^0 rapidity, transverse momentum of Z^0 as well as in relative azimuthal angle between outgoing protons. The contributions of different flavours are discussed. Absorption effects lower the cross section by a factor of 1.5-2, depending on the Z-boson rapidity. We also discuss the production of Z^0 bosons in central inclusive production. Here rapidity and (x_{\Pom,1}, x_{\Pom,2}) distributions of Z^0 are calculated. The corresponding cross section is about three orders of magnitude larger than that for the purely exclusive process.

description: Le phénomène d'îlot de chaleur urbain accentue les effets des vagues de chaleur qui deviendront plus fréquentes sur des territoires fortement peuplés. Actuellement, 50\% de la population mondiale vit dans des villes et ce chiffre devrait atteindre 70\% d'ici 2050. Pour prévenir et s'adapter aux canicules en zone urbaine il est essentiel de disposer d'outils numériques de prédiction des transferts thermiques couplés qui prennent en compte la complexité géométrique de la ville. De nouveaux modèles micro-météorologiques sont alors nécessaires qui couplent l'écoulement turbulent et la thermique. Les méthodes déterministes étant limitées par la taille du domaine à représenter, nous proposons un modèle basé sur une méthode probabiliste pour simuler les transferts thermiques couplés dans et entre les bâtiments d'une géométrie urbaine complexe. Le développement d'un modèle probabiliste de transferts couplés conducto-radiatif linéarisé et transitoire est présenté. Ce modèle inclue des conditions limites de type Robin et un modèle de ciel avec un flux solaire direct et diffus. La méthode de Monte-Carlo (MC) est utilisée pour la résolution du modèle probabiliste avec une randomisation des contributions des différents modes de transferts de chaleur à la paroi où s'appliquent une condition de Robin (conduction, convection, rayonnement thermique et solaire). MC permet une résolution précise des échanges de chaleur et une vision des chemins de propagation des sources qui aide à mieux comprendre et prédire les échanges de chaleur en milieu urbain. En outre, MC est une méthode massivement parallélisable qui rend théoriquement possible le passage à l'échelle des simulations et des modèles. Nous faisons ici la preuve de concept de ce passage à l'échelle à l'aide du programme Stardis (https://www.meso-star.com/projects/stardis/stardis.html), un outil libre de simulation numérique de transferts thermiques couplés par la méthode Monte-Carlo, que nous avons enrichi d'un modèle de ciel pour le rayonnement solaire et thermique. La validation numérique du code est présentée pour la partie conduction, la partie rayonnement en géométrie complexe et le modèle de ciel.
