Data-driven degradation modeling of lithium-ion batteries
Creators: name: Wang, Yixiu
Publisher: name: University of British Columbia

description: Ensuring the safe and reliable usage of Lithium-ion batteries (LIBs) necessitates accurate degradation modeling. While data-driven methods offer promising prospects for modeling battery degradation, the intricate structures often make them specific to datasets. Furthermore, the black-box nature of data-driven models complicates the understanding of their decision-making process. In this thesis, we delve into data-driven modeling of battery degradation, focusing on capacity estimation and cycle life prediction, to address the challenges of generalizability and interpretability. To improve the generalizability of the model, we first propose adopting a simple and robust machine learning model, partial least squares regression (PLSR), for joint battery capacity estimation and remaining useful life (RUL) prediction. Experimental results on three battery cells cycled at varied conditions demonstrate superior generalizability of the suggested model over complex and sophisticated methods. Another approach we propose to improve the generalizability of the model is to use transfer learning. This approach presents excellent performance in handling the significant diversity in different types of batteries, as it can transfer the knowledge contained in well-studied batteries to a new battery. The key idea involves training a model in one type of battery with sufficient data. Then, the model can be applicable to a new type of battery by fine-tuning some parameters with limited data. Experimental results confirm that transfer learning can effectively enhance the generalizability of data-driven models in capacity estimation and cycle life prediction across different battery types. To build interpretable models, we advocate the use of decision trees for capacity estimation. We start with a classic regression tree with parallel splits for capacity estimation, but it requires a tree depth of 11 to achieve satisfactory performance. To address this challenge, we adopt optimal regression trees with hyperplane splits and propose a novel algorithm, DE-LR-ORTH, to train such a tree. DE-LR-ORTH initially conducts a one-step optimal hyperplane split for each branch node via differential evolution, followed by logistic regression-based fine-tuning to achieve overall optimality. Additionally, a GPU-accelerated implementation is proposed to significantly reduce the training time. Experimental results reveal a 1.0% capacity estimation error at depth 6 while maintaining high interpretability.

description: This communication reports the formation of complex Langmuir monolayer at the air-water interface by charge transfer types of interaction with the water soluble N- cetyl N, N, N trimethyl ammonium bromide (CTAB) molecules doped with rosebengal (RB), with the stearic acid (SA) molecules of a preformed SA Langmuir monolayer. The reaction kinetics of the formation of RB-CTAB-SA complex monolayer was monitored by observing the increase in surface pressure with time while the barrier was kept fixed. Completion of interaction kinetics was confirmed by FTIR study. This complex Langmuir films at the air-water interface was transferred onto solid substrates at a desired surface pressure to form multilayered Langmuir-Blodgett films. Spectroscopic characterizations reveal some molecular level interactions as well as formation of microcrystalline aggregates depending upon the molar ratios of CTAB and RB within the complex LB films. Presence of two types of species in the complex LB films was confirmed by fluorescence spectroscopy.

description: In lattice QCD, a confining potential for a static quark-antiquark pair can be computed with the Wilson loop technique. This potential, dominated by a linear potential at moderate distances, is consistent with the confinement with a flux tube, an extended and scalar system also directly observable in lattice QCD. Quantized flux tubes have also been observed in another class of confinement, the magnetic confinement in type II superconductors. On the other hand the solution of Schwinger Dyson Equations, say with the Landau gauge fixing and the truncation of the series of Feynman diagrams, already at the rainbow level for the self energy and at the ladder level for the Bethe Salpeter equation, provides a signal of a possible inverse quartic potential in momentum space derived from one gluon and one ghost exchange, consistent with confinement. Here we address the successes, difficulties and open problems of the matching of these two different perspectives of confinement, the Schwinger-Dyson perspective versus the flux tube perspective.

description: We survey odd-even nuclear binding energy staggering using density functional theory with several treatments of the pairing interaction including the BCS, Hartree-Fock-Bogoliubov, and the Hartree-Fock-Bogoliubov with the Lipkin-Nogami approximation. We calculate the second difference of binding energies and compare with 443 measured neutron energy differences in isotope chains and 418 measured proton energy differences in isotone chains. The particle-hole part of the energy functional is taken as the SLy4 Skyrme parametrization and the pairing part of the functional is based on a contact interaction with possible density dependence. An important feature of the data, reproduced by the theory, is the sharp gap quenching at magic numbers. With the strength of the interaction as a free parameter, the theory can reproduce the data to an rms accuracy of about 0.25 MeV. This is slightly better than a single-parameter phenomenological description but slightly poorer than the usual two-parameter phenomenological form C/A^alpha . The following conclusions can be made about the performance of common parametrization of the pairing interaction: (i) there is a weak preference for a surface-peaked neutron-neutron pairing, which might be attributable to many-body effects; (ii) a larger strength is required in the proton pairing channel than in the neutron pairing channel; (iii) pairing strengths adjusted to the well-known spherical isotope chains are too weak to give a good overall fit to the mass differences.

description: We study high-stress SiN films for reaching the quantum regime with mesoscopic oscillators connected to a room-temperature thermal bath, for which there are stringent requirements on the oscillators' quality factors and frequencies. Our SiN films support mechanical modes with unprecedented products of mechanical quality factor $Q_m$ and frequency $ν_m$ reaching $Q_{m} ν_m \simeq2 \times 10^{13}$ Hz. The SiN membranes exhibit a low optical absorption characterized by Im$(n) \lesssim 10^{-5}$ at 935 nm, representing a 15 times reduction for SiN membranes. We have developed an apparatus to simultaneously cool the motion of multiple mechanical modes based on a short, high-finesse Fabry-Perot cavity and present initial cooling results along with future possibilities.

Determining residual stress using indentation and surface displacement measurement
Creators: name: Vaidyanathan, Sidhant Sunder
Publisher: name: University of British Columbia
Year: 2023

description: Residual stresses are stresses that are “locked-in” within a material, existing independently of external loads. Measuring residual stresses accurately can be beneficial for a wide range of engineering applications. The indentation method to determine residual stress is an attractive choice over current methods like Hole-Drilling due to simplicity of instrumentation and less damage to the specimen. The currently used procedure is the Force-Depth method where the indentation force is measured for constant depth of indentation on a stress-relaxed specimen vs. a specimen with residual stress. Though convenient, this method cannot distinguish the directions and separate sizes of the in-plane residual stresses. In this thesis, a novel approach is proposed using full-field optical techniques to capture rich surface displacement data from millions of pixels, in contrast to a single data source from an indentation force measurement. These data are used to determine the magnitude of residual stresses on metal surfaces for an isotropic residual stress distribution case. In this approach, finite element simulations are used to study the relationship between surface displacement and in-plane residual stresses. The studied characteristics are used to create a quantitative relationship between surface displacement and residual stress. These calibration values correlate well with corresponding experiments on steel specimens and serve as proof of concept for the proposed method to measure residual stress. Further avenues to improve the method are discussed in conclusion.

description: This article completes a former work where part of the O(p^6) low-energy constants entering in the pi pi scattering were estimated. Some resonance contributions were missed in former calculations and slight differences appeared with respect to our outcome. Here, we provide the full results for all the contributing O(p^6) couplings. We also perform a reanalysis of the hadronic inputs used for the estimation (resonance masses, widths...). Their reliability was checked together with the impact of the input uncertainties on the determinations of the chiral couplings and the scattering lengths a^I_J. Our outcome is found in agreement with former works though with slightly larger errors. However, the effect in the final values of the a^I_J is negligible after combining them with the other uncertainties. Based on this consistency, we conclude that the previous scattering length determinations seem to be rather solid and reliable, with the cO(p^6) low-energy constants quite under control. Nevertheless, the uncertainties found in the present work point out the limitation on further improvements unless the precision of the O(p^6) couplings is properly increased.

description: We present a search for long-period variable (LPV) stars among giant branch stars in M15 which, at [Fe/H] ~ -2.3, is one of the most metal-poor Galactic globular clusters. We use multi-colour optical photometry from the 0.6-m Keele Thornton and 2-m Liverpool Telescopes. Variability of delta-V ~ 0.15 mag is detected in K757 and K825 over unusually-long timescales of nearly a year, making them the most metal-poor LPVs found in a Galactic globular cluster. K825 is placed on the long secondary period sequence, identified for metal-rich LPVs, though no primary period is detectable. We discuss this variability in the context of dust production and stellar evolution at low metallicity, using additional spectra from the 6.5-m Magellan (Las Campanas) telescope. A lack of dust production, despite the presence of gaseous mass loss raises questions about the production of dust and the intra-cluster medium of this cluster.

Linear model for fast background subtraction in oligonucleotide microarrays

description: One important preprocessing step in the analysis of microarray data is background subtraction. In high-density oligonucleotide arrays this is recognized as a crucial step for the global performance of the data analysis from raw intensities to expression values. We propose here an algorithm for background estimation based on a model in which the cost function is quadratic in a set of fitting parameters such that minimization can be performed through linear algebra. The model incorporates two effects: 1) Correlated intensities between neighboring features in the chip and 2) sequence-dependent affinities for non-specific hybridization fitted by an extended nearest-neighbor model. The algorithm has been tested on 360 GeneChips from publicly available data of recent expression experiments. The algorithm is fast and accurate. Strong correlations between the fitted values for different experiments as well as between the free-energy parameters and their counterparts in aqueous solution indicate that the model captures a significant part of the underlying physical chemistry.

description: We analyze the quantum ground state structure of a specific model of itinerant, strongly interacting lattice fermions. The interactions are tuned to make the model supersymmetric. Due to this, quantum ground states are in one-to-one correspondence with cohomology classes of the so-called independence complex of the lattice. Our main result is a complete description of the cohomology, and thereby of the quantum ground states, for a two-dimensional square lattice with periodic boundary conditions. Our work builds on results by J. Jonsson, who determined the Euler characteristic (Witten index) via a correspondence with rhombus tilings of the plane. We prove a theorem, first conjectured by P. Fendley, which relates dimensions of the cohomology at grade n to the number of rhombus tilings with n rhombi.

description: Effective Casimir forces induced by thermal fluctuations in the vicinity of bulk critical points are studied by means of Monte Carlo simulations in three-dimensional systems for film geometries and within the experimentally relevant Ising and XY universality classes. Several surface universality classes of the confining surfaces are considered, some of which are relevant for recent experiments. A novel approach introduced previously EPL 80, 60009 (2007), based inter alia on an integration scheme of free energy differences, is utilized to compute the universal scaling functions of the critical Casimir forces in the critical range of temperatures above and below the bulk critical temperature. The resulting predictions are compared with corresponding experimental data for wetting films of fluids and with available theoretical results.

description: In the context of the United Nations Security Council (UNSC), the debate on whether climate change should be included and how has been ongoing since 2007. This article contributes to existing research on this problem by expounding a three-fold analysis. First, it assesses the conceptual approach to the climate-security nexus from the joint statement of 10 UNSC member states in 2020. Second, it critically exposes the confusion of different climate-security conceptions and uncovers shared assumptions of the UNSC-member states in 2020 by comparing their different positions, which makes a soon-to-come agreement likely. Third, it critically evaluates whether the proposal to include climate change into the UNSC will lead to a transformative change of the institution, of the meaning of security, and on how this would correspond to the existential threats outlined in the Anthropocene context. The theoretical framework of analysis draws on critical security studies. It takes as its empirical basis the primary sources of the UNSC debate of 2020 and is also informed by the secondary literature on climate and security and the Earth System Sciences descriptions of the state of the planet.

description: We calculate the temperature dependent condensate density $ρ^0 (T)$ of interacting bosons in three dimensions using the functional renormalization group (FRG). From the numerical solution of suitably truncated FRG flow equations for the irreducible vertices we obtain $ρ^0 (T)$ for arbitrary temperatures. We carefully extrapolate our numerical results to the critical point and determine the order parameter exponent $β\approx 0.32$, in reasonable agreement with the expected value $ 0.345$ associated with the XY-universality class. We also calculate the condensate density in two dimensions at zero temperature using a truncation of the FRG flow equations based on the derivative expansion including cubic and quartic terms in the expansion of the effective potential in powers of the density. As compared with the widely used quadratic approximation for the effective potential, the coupling constants associated with the cubic and quartic terms increase the result for the condensate density by a few percent. However, the cubic and quartic coupling constants flow to rather large values, which sheds some doubt on FRG calculations based on a low order polynomial approximation for the effective potential.

description: The study of warm molecular gas in the inner regions of protoplanetary disks is of key importance for the study of planet formation and especially for the transport of H2O and organic molecules to the surfaces of rocky planets/satellites. Recent Spitzer observations have shown that the mid-infrared spectra of protoplanetary disks are covered in emission lines due to water and other molecules. Here, we present a non-LTE 2D radiative transfer model of water lines in the 10-36 mum range that can be used to constrain the abundance structure of water vapor, given an observed spectrum, and show that an assumption of local thermodynamic equilibrium (LTE) does not accurately estimate the physical conditions of the water vapor emission zones. By applying the model to published Spitzer spectra we find that: 1) most water lines are subthermally excited, 2) the gas-to-dust ratio must be one to two orders of magnitude higher than the canonical interstellar medium ratio of 100-200, and 3) the gas temperature must be higher than the dust temperature, and 4) the water vapor abundance in the disk surface must be truncated beyond ~ 1 AU. A low efficiency of water formation below ~ 300 K may naturally result in a lower water abundance beyond a certain radius. However, we find that chemistry, may not be sufficient to produce an abundance drop of many orders of magnitude and speculate that the depletion may also be caused by vertical turbulent diffusion of water vapor from the superheated surface to regions below the snow line, where the water can freeze out and be transported to the midplane as part of the general dust settling. Such a vertical cold finger effect is likely to be efficient due to the lack of a replenishment mechanism of large, water-ice coated dust grains to the disk surface.

Distribution, habitat associations, and threats to Patagonian seahorses in an Argentine protected area
Creators: name: Templeton, Pax
Publisher: name: University of British Columbia

description: Effective conservation of rare and threatened marine species is reliant on a robust understanding of their distribution patterns and habitat associations. In this thesis, I carried out the first in situ dive study on spatial distribution, biological traits, ecological correlates, and habitat features for the most significant (and most southerly) population of the Patagonian seahorse in Argentina (Hippocampus patagonicus, Vulnerable on the IUCN Red List). I conducted dive surveys within the 690 km² marine portion of the Bahia San Antonio (BSA) Protected Area of Rio Negro Province, Argentina during the H. patagonicus breeding season in the austral late spring. I found that seahorses showed patchy distributions with significantly higher densities inside the sheltered waters of the BSA than in the Gulf of San Matias (GSM), with density ranging from 0.1 – 12.0 individuals/100m², and a mean density of 1.5 individuals/100 m² across the entire area sampled. Seahorses were most abundant in subtidal sandy and macroalgae bed habitats that featured denser algae coverage and a greater diversity of holdfast species. Seahorses were negatively associated with subtidal sandy-muddy and subtidal rocky reef habitats. Over half the seahorses (55%, n=136) sampled were found using brown and red algae as holdfasts. Despite its designation, the BSA Protected Area is subject to ongoing anthropogenic pressures including fisheries, pollution from poorly planned urban and industrial development, invasive species, and unsustainable levels of tourism. It is critical that regional management safeguard zones and habitat types that support high seahorse density. Such habitat protections will provide spillover benefits to other marine species that rely on the BSA Protected Area as a nursing and breeding ground.

description: We present measurements of the dissipation and frequency shift in nanomechanical gold resonators at temperatures down to 10 mK. The resonators were fabricated as doubly-clamped beams above a GaAs substrate and actuated magnetomotively. Measurements on beams with frequencies 7.95 MHz and 3.87 MHz revealed that from 30 mK to 500 mK the dissipation increases with temperature as $T^{0.5}$, with saturation occurring at higher temperatures. The relative frequency shift of the resonators increases logarithmically with temperature up to at least 400 mK. Similarities with the behavior of bulk amorphous solids suggest that the dissipation in our resonators is dominated by two-level systems.

description: The 18.6 keV antineutrino line from 2-body decay of 3H in crystals can be emitted with natural width because of motional averaging by lattice vibrations despite the very long lifetime of 3H and contrary to commonly held views of linewidths in such a case. It can be resonantly captured in 3He with geometrical cross section sigma ~10-17 cm2. Using its hypersharp sensitivity DELTAE/E ~10-29 and the method of time-filtered resonance, the basic energy width ~10-24 eV expected of the 3H state can be measured to test if ultimate nuclear widths are limited by the Planck length rather than time-energy uncertainty.

The D0$-$D8 system revisited
Creators: name: Lu, J. X.
name: Wu, Rong-Jun
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We address a few subtle issues regarding the interacting D0-D8 system. There are two existing interpretations for the counter-intuitive non-vanishing cylinder-diagram R-R potential. We improve them each by properly dealing with the divergence of potential in the R-R as well as the NS-NS sector, which has been ignored so far. We further test them by considering the D8 to carry a flux, electric or magnetic. We find that the improved interpretations continue to hold. We resolve a subtle issue regarding the regularization of fermionic zero-modes in the R-R sector when the D8 carries an electric flux so that a meaningful result for the potential can be calculated. The persistence of divergence for the potential in either sector in the presence of a flux on the D8 brane indicates that adding a flux/fluxes on the D8 brane doesn't help to improve its nature of existence as an independent object, therefore reenforcing the previous assertion on D8 branes.

description: The debiting process of the remarkable properties materials can be managed through unconventional technologies as the complex electrical erosion. We present the modeling of the previous experimental results to obtain a mathematical dependence of the output parameters (processing time, surface quality) on the input parameters (voltage or current). All the experimental data are memorized on a database and for each particular debiting process a new dependence is built. Because all the experiments applied in the Romanian laboratories or practical applications of the nonconventional technological processes in the factories were based on the particular conditions of one activity, this papers presents the technical implementation of a computer-aided solution that keeps all previous experimental data, optimizes the processing conditions and eventual manage the driving gear. The flow-chart we present in this paper offers a solution for practitioners to reduce the electrical consumption while a technological processing of special materials is necessary. The computer program and the database can be easily adapted to any technological processes (conventional or not).

Improving language models with novel contrastive learning objectives
Creators: name: Khondaker, Md Tawkat Islam
Publisher: name: University of British Columbia
Year: 2023

description: Contrastive learning (CL) has recently emerged as an effective technique in natural language processing, especially in the important area of language modeling. In this work, we offer novel methods for deploying CL in both pretraining and finetuning of language models. First, we present PACT (Pretraining with Adversarial Contrastive Learning for Text Classification), a novel self-supervised framework for text classification. Instead of contrasting against in-batch negatives, a popular approach in the literature, PACT mines negatives closer to the anchor representation. PACT operates by endowing the standard pretraining mechanisms of BERT with adversarial contrastive learning objectives, allowing for effective joint optimization of token- and sentence-level pretraining of the BERT model. Our experiments on 13 diverse datasets including token-level, single-sentence, and sentence-pair text classification tasks show that PACT achieves consistent improvements over SOTA baselines. We further show that PACT regularizes both token-level and sentence-level embedding spaces into more uniform representations, thereby alleviating the undesirable anisotropic phenomenon of language models. Subsequently, in the context of finetuning, we apply CL in tackling cross-platform abusive language detection. The prevalence of abusive language on different online platforms has been a major concern that raises the need for automated cross-platform abusive language detection. However, prior works focus on concatenating data from multiple platforms, inherently adopting Empirical Risk Minimization (ERM) method. In our work, we address this challenge from the perspective of domain generalization objective. We design SCL-Fish, a supervised contrastive learning integrated meta-learning algorithm to detect abusive language on unseen platforms. Our experimental analysis shows that SCL-Fish achieves better performance over ERM and the existing state-of-the-art models. We also show that SCL-Fish is data-efficient and achieves comparable performance with the large-scale pretrained models upon finetuning for the abusive language detection task.

The Role of Uncertainty for Product Announcement Strategies: The Case of Autonomous Vehicles

description: We study how uncertainty about performance and safety of autonomous vehicles (AV) influences the success of two prototypical strategies governing the producers’ timing of the release of new models. Producers can announce the date of the next market introduction or commit to a minimum quality level. Consumers might opt to purchase a new AV, delay the purchasing decision, or resort to purchasing a conventional vehicle. Relying on a calibrated agent-based simulation model, we show that committing on the quality level of the new release yields a competitive advantage and investigate how the degree of uncertainty and consumer attitude toward uncertainty influence the relative performance of strategies and market diffusion of AVs.
Thermal effects on chaotic directed transport
Creators: name: Carlo, Gabriel G.

Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study a chaotic ratchet system under the influence of a thermal environment. By direct integration of the Lindblad equation we are able to analyze its behavior for a wide range of couplings with the environment, and for different finite temperatures. We observe that the enhancement of the classical and quantum currents due to temperature depend strongly on the specific properties of the system. This makes difficult to extract universal behaviors. We have also found that there is an analogy between the effects of the classical thermal noise and those of the finite $\hbar$ size. These results open many possibilities for their testing and implementation in kicked BECs and cold atoms experiments.

title: A critical analysis of looked after children in Trinidad and Tobago, West
      Indies
title: an ethnographic study
titleType: Subtitle
Creators: name: Williams, Khadijah
Publisher: name: Lancaster University
Year: 2015

description: The study was informed by an interest in the relational aspects of
      children’s participation and how children’s participation can practically
      be shifted from being a transactional experience to a transformational,
      participatory experience. It highlights the complexity of the issues
      involved in children’s participation and how it actually works in practice
      in a residential child care context. It provides deeper insights into the
      social, cultural and political issues that influence how children
      participate and relates these to the larger discourse of development
      ethics, children’s citizenship and agency.

      Ethnographic research was conducted in two major children’s homes in
      Trinidad and Tobago for a period of two years where children’s
      participation in decision making processes was the key focus of attention.
      Data analysis using a combination of the scientific qualitative software,
      Atlas.ti7, and the constant comparative method, revealed five essential
      themes related to the participation experiences of children in residential
      care. These themes are: the complexity of caring relationships between
      adults and children; participation, paternalism, resistance and
      resilience; Information and Communication Technologies (ICTs) as a new
      site of conflict for children’s participation; how adults and looked after
      children negotiated meaning at the broader policy level and positive
      aspects of residential child care. A combination of ideas from development
      ethics, critical social work theory, children’s agency and care ethics has
      been applied to the analysis of children’s participation, which includes
      four key areas: (1) the meaning of increasing children’s agency in
      residential care; (2) the interdependence of adults and looked after
      children; (3) children’s participation as an indigenous experience and (4)
      children’s experiences as collective decision makers.

      This research therefore presents useful insights into children’s
      participation in post-colonial Trinidad and Tobago and presents findings
      which challenge traditional assumptions held about children by adults as
      being incompetent and dependent. It also provides an alternative approach
      to understanding children’s participation which incorporates adult-child
      relations as opposed to only taking a rights-based approach. Although the
      findings cannot be generalised to all children’s experiences regarding
      participation, knowledge about how to identify children’s participation
      and its relational issues might be transferable. There are lessons from
      the adults’ and children’s experiences which will be useful to policy
      makers, researchers, children themselves and practitioners in the field of
      child welfare and children’s rights.
