Settling and consolidation behaviour of coal tailings slurry under continuous loading
Creators: name: Shokouhi, A.
name: Williams, D. J.
Publisher: name: The University of British Columbia
Year: 2016

description: Tailings are generated as the fine-grained wastes on the washing of run-of-mine coal to meet market specifications. Coal tailings are typically sand-sized and finer, and are pumped as an aqueous slurry at a solids concentration of typically 25% solids by mass, conventionally to a surface tailings storage facility. The physical processes that coal tailings undergo on sub-aerial disposal to a surface tailings storage facility include beaching, hydraulic sorting, settling, self-weight consolidation and desiccation. The settling and consolidation of coal tailings, the topic of this paper, have the most profound effect on the volume that the deposited tailings occupy. These processes are particularly important where the rate of rise is rapid and/or deposition is under water. Settling occurs in the upper part of the recently deposited tailings layer, while consolidation occurs simultaneously towards the base of the layer. The two processes of settling and consolidation are conventionally tested separately in the laboratory; settling in a column and consolidation in a consolidometer. This paper describes a purpose-built, large, slurry consolidometer, in which coal tailings slurry is added in three layers at a nominal 25% solids by mass, allowed to settle between layers, and consolidated under three different continuous loading sequences. Thus the two processes of settling and consolidation are carried out in the same testing apparatus, from an initial consistency representative of field conditions.

description: We study the seismic inverse problem for the recovery of subsurface properties in acoustic media. In order to reduce the ill-posedness of the problem, the heterogeneous wave speed parameter to be recovered is represented using a limited number of coefficients associated with a basis of eigenvectors of a diffusion equation, following the regularization by discretization approach. We compare several choices for the diffusion coefficient in the partial differential equations, which are extracted from the field of image processing. We first investigate their efficiency for image decomposition (accuracy of the representation with respect to the number of variables and denoising). Next, we implement the method in the quantitative reconstruction procedure for seismic imaging, following the Full Waveform Inversion method, where the difficulty resides in that the basis is defined from an initial model where none of the actual structures is known. In particular, we demonstrate that the method is efficient for the challenging reconstruction of media with salt-domes. We employ the method in two and three-dimensional experiments and show that the eigenvector representation compensates for the lack of low frequency information, it eventually serves us to extract guidelines for the implementation of the method.

description: The observed CMBR dipole is generally interpreted as a Doppler effect arising from the motion of the Earth relative to the CMBR frame. An alternative interpretation, proposed in the last years, is that the dipole results from ultra-large scale isocurvature perturbations. We examine this idea in the context of open cosmologies and show that the isocurvature interpretation is not valid in an open universe, unless it is extremely close to a flat universe, $|Ω_0 -1|< 10^{-4}$.

description: Advances in techniques have been producing increasingly complex neural recordings, posing significant challenges for data analysis. This thesis discusses novel statistical methods for analyzing high-dimensional neural data. Part one discusses two extensions of state space models tailored to neural data analysis. First, we propose using a flexible count data distribution family in the observation model to faithfully capture over-dispersion and under-dispersion of the neural observations. Second, we incorporate nonlinear observation models into state space models to improve the flexibility of the model and get a more concise representation of the data. For both extensions, novel variational inference techniques are developed for model fitting, and simulated and real experiments show the advantages of our extensions. Part two discusses a fast region of interest (ROI) detection method for large-scale calcium imaging data based on structured matrix factorization. Part three discusses a method for sampling from a maximum entropy distribution with complicated constraints, which is useful for hypothesis testing for neural data analysis and many other applications related to maximum entropy formulation. We conclude the thesis with discussions and future works.
title: Entrainment to speech rhythm from perception to production
Creators: name: Beith, Alistair
Publisher: name: University of Glasgow

description: Human speech comprehension requires a highly coordinated engagement of linguistic processes. Speech contains complex layers of information to be decoded and often acted on just-in-time. This thesis explores the possible role of speech rhythm in connecting the speech we hear to the speech we produce. Two methodological chapters are presented. The first reviews and evaluates different approaches to creating rhythmic speech stimuli. The second highlights the challenges of collecting precise and accurate auditory response times in web-based experiments. These methods are then applied to a series of three experiments, each building on the last. In a new experimental paradigm, participants responded verbally to simple maths sums where tempo and rhythm were manipulated. Both time-domain and frequency-domain analyses found effects of stimulus tempo on the timing of responses.

description: DNA methylation plays a crucial role in human health, especially cancer. Traditional DNA methylation analysis aims to identify CpGs/genes with differential methylation (DM) between experimental groups. Differential variability (DV) was recently observed that contributes to cancer heterogeneity and was also shown to be essential in detecting early DNA methylation alterations, notably epigenetic field defects. Moreover, studies have demonstrated that environmental factors may modify the effect of DNA methylation on health outcomes, or vice versa. Therefore, this dissertation seeks to develop new statistical methods for epigenetic data focusing on DV and interactions when efficient analytical tools are lacking. First, as neighboring CpG sites are usually highly correlated, we introduced a new method to detect differentially methylated regions (DMRs) that uses combined DM and DV signals between diseased and non-diseased groups. Next, using both DM and DV signals, we considered the problem of identifying epigenetic field defects, when CpG-site-level DM and DV signals are minimal and hard to be detected by existing methods. We proposed a weighted epigenetic distance-based method that accumulates CpG-site-level DM and DV signals in a gene. Here DV signals were captured by a pseudo-data matrix constructed using centered quadratic methylation measures. CpG-site-level association signal annotations were introduced as weights in distance calculations to up-weight signal CpGs and down-weight noise CpGs to further boost the study power. Lastly, we extended the weighted epigenetic distance-based method to incorporate DNA methylation by environment interactions in the detection of overall association between DNA methylation and health outcomes. A pseudo-data matrix was constructed with cross-product terms between DNA methylation and environmental factors that is able to capture their interactions. The superior performance of the proposed methods were shown through intensive simulation studies and real data applications to multiple DNA methylation data.

description: Modern neurotechnologies enable the recording of neural activity at the scale of entire brains and with single-cell resolution. However, the lack of principled approaches to extract structure from these massive data streams prevent us from fully exploiting the potential of these technologies. This thesis, divided in three parts, introduces new statistical machine learning methods to enable the large-scale analysis of some of these complex neural datasets. In the first part, I present a method that leverages Gaussian quadrature to accelerate inference of neural encoding models from a certain type of observed neural point processes --- spike trains --- resulting in substantial improvements over existing methods.
      The second part focuses on the simultaneous electrical stimulation and recording of neurons using large electrode arrays. There, identification of neural activity is hindered by stimulation artifacts that are much larger than spikes, and overlap temporally with spikes. To surmount this challenge, I develop an algorithm to infer and cancel this artifact, enabling inference of the neural signal of interest. This algorithm is based on a a bayesian generative model for recordings, where a structured gaussian process is used to represent prior knowledge of the artifact. The algorithm achieves near perfect accuracy and enables the analysis of data hundreds of time faster than previous approaches.
      The third part is motivated by the problem of inference of neural dynamics in the worm C.elegans: when taking a data-driven approach to this question, e.g., when using whole-brain calcium imaging data, one is faced with the need to match neural recordings to canonical neural identities, in practice resolved by tedious human labor. Alternatively, on a bayesian setup this problem may be cast as posterior inference of a latent permutation. I introduce methods that enable gradient-based approximate posterior inference of permutations, overcoming the difficulties imposed by the combinatorial and discrete nature of this object. Results suggest the feasibility of automating neural identification, and demonstrate variational inference in permutations is a sensible alternative to MCMC.

description: In current lattice simulations of nucleon properties, the up and down quark masses are significantly larger than their physical values, while the strange quark can be included in simulations with its physical mass. When the up and down quark masses are much smaller than the strange-quark mass the chiral extrapolation of strange-quark matrix elements in the nucleon from the lattice up and down quark masses to their physical values can be performed with two-flavor chiral perturbation theory, thereby avoiding the slow convergence problem of the three-flavor chiral expansion. We explore the chiral expansion of several matrix elements of strange operators in the nucleon in two-flavor chiral perturbation theory and two-flavor partial-quenched chiral perturbation theory.

description: We consider a Fog Radio Access Network (F-RAN) with a Base Band Unit (BBU) in the cloud and multiple cache-enabled enhanced Remote Radio Heads (eRRHs). The system aims at delivering contents on demand with minimal average latency from a time-varying library of popular contents. Information about uncached requested files can be transferred from the cloud to the eRRHs by following either backhaul or fronthaul modes. The backhaul mode transfers fractions of the requested files, while the fronthaul mode transmits quantized baseband samples as in Cloud-RAN (C-RAN). The backhaul mode allows the caches of the eRRHs to be updated, which may lower future delivery latencies. In contrast, the fronthaul mode enables cooperative C-RAN transmissions that may reduce the current delivery latency. Taking into account the trade-off between current and future delivery performance, this paper proposes an adaptive selection method between the two delivery modes to minimize the long-term delivery latency. Assuming an unknown and time-varying popularity model, the method is based on model-free Reinforcement Learning (RL). Numerical results confirm the effectiveness of the proposed RL scheme.

description: Josephson-junction based parametric amplifiers have become a ubiquitous component in superconducting quantum machines. Although parametric amplifiers regularly achieve near-quantum limited performance, they have many limitations, including low saturation powers, lack of directionality, and narrow bandwidth. The first is believed to stem from the higher order Hamiltonian terms endemic to Josephson junction circuits, and the latter two are direct consequences of the nature of the parametric interactions which power them. In this work, we attack both of these issues. First, we have designed a new, linearly shunted Josephson Ring Modulator (JRM) which nearly nulls all 4th-order terms at a single flux bias point. Next, we achieve gain through a pair of balanced parametric drives. When applied separately, these drives produce phase-preserving gain (G) and gainless photon conversion (C), when applied together, the resultant amplifier (which we term GC) is a bi-directional, phase-sensitive transmission-only amplifier with a large, gain-independent bandwidth. Finally, we have also demonstrated the practical utility of the GC amplifier, as well as its' quantum efficiency, by using it to read out a superconducting transmon qubit.

description: The HAWC Collaboration has discovered a $γ$-ray emission extended about 2 degrees around the Geminga and Monogem pulsar wind nebulae (PWNe) at $γ$-ray energies $E_γ>5$ TeV. We analyze, for the first time, almost 10 years of $γ$-ray data obtained with the Fermi Large Area Telescope at $E_γ>$ 8 GeV in the direction of Geminga and Monogem. Since these two pulsars are close the Galactic plane we run our analysis with 10 different interstellar emission models (IEMs) to study the systematics due to the modeling of this component. We detect a $γ$-ray halo around Geminga with a significance in the range $7.8-11.8σ$ depending on the IEM considered. This measurement is compatible with $e^+$ and $e^-$ emitted by the PWN, which inverse-Compton scatter (ICS) with photon fields located within a distance of about 100 pc from the pulsar, where the diffusion coefficient is estimated to be around $1.1 \times 10^{27}$ cm$^2$/s at 100 GeV. We include in our analysis the proper motion of the Geminga pulsar which is relevant for $γ$ rays produced for ICS in the Fermi-LAT energy range. We find that an efficiency of about $1\%$ for the conversion of the spin-down energy of the pulsar into $e^+$ and $e^-$ is required to be consistent with $γ$-ray data from Fermi-LAT and HAWC. The inferred contribution of Geminga to the $e^+$ flux is at most $20\%$ at the highest energy AMS-02 data. Our results are compatible with the interpretation that the cumulative emission from Galactic pulsars explains the positron excess.

description: The thermal conductivity of the color-flavor locked phase of dense quark matter is calculated. The dominant contribution to the conductivity comes from photons and Nambu-Goldstone bosons associated with the breaking of baryon number, both of which are trapped in the quark core. Because of their very large mean free path the conductivity is also very large. The cooling of the quark core arises mostly from the heat flux across the surface of direct contact with the nuclear matter. As the thermal conductivity of the neighboring layer is also high, the whole interior of the star should be nearly isothermal. Our results imply that the cooling time of compact stars with color-flavor locked quark cores is similar to that of ordinary neutron stars.

description: Inspired by the TCGA (The Cancer Genome Atlas), we explore multimodal genomic datasets with integrative methods using a joint latent variable approach. We use iCluster+, an existing clustering method for integrative data, to identify potential subtypes within TCGA sarcoma and mesothelioma tumors, and across a large cohort of 33 dierent TCGA cancer datasets. For classication, motivated to improve the prediction of platinum resistance in high grade serous ovarian cancer (HGSOC) treatment, we propose novel integrative methods, iClassify to perform classication using a joint latent variable model. iClassify provides eective data integration and classication while handling heterogeneous data types, while providing a natural framework to incorporate covariate risk factors and examine genomic driver by covariate risk factor interaction. Feature selection is performed through a thresholding parameter that combines both latent variable and feature coecients. We demonstrate increased accuracy in classication over methods that assume homogeneous data type, such as linear discriminant analysis and penalized logistic regression, and improved feature selection. We apply iClassify to a TCGA cohort of HGSOC patients with three types of genomic data and platinum response data. This methodology has broad applications beyond predicting treatment outcomes and disease progression in cancer, including predicting prognosis and diagnosis in other diseases with major public health implications.

description: The properties of a transformation previously considered for generating new perfect-fluid solutions from known ones are further investigated. It is assumed that the four-velocity of the fluid is parallel to the stationary Killing field, and also that the norm and the twist potential of the stationary Killing field are functionally related. This case is complementary to the case studied in our previous paper. The transformation can be applied to generate possibly new perfect-fluid solutions from known ones only for the case of barotropic equation of state rho+3p=0 or, alternatively, for the case of a static spacetime. For static spacetimes our method recovers the Buchdahl transformation. It is demonstrated, moreover, that Herlt's technique for constructing stationary perfect-fluid solutions from static ones is, actually, a special case of the method considered in the present paper.

description: A series of supplementary geotechnical investigations were conducted at the Questa Mine Site in 2013 and 2014 to collect additional information regarding the waste rock piles located on the site. These investigations highlighted the effects that different drilling and sampling methods can have on soil samples and the associated geotechnical laboratory characterization testing. Samples were collected from a series of collocated Becker borings and test pits and particle size distributions were determined for the samples collected from the two different investigation and sampling methods. The Becker samples had 3 percent more material passing the number 200 sieve and 11 percent more material passing the number 4 sieve than the test pit samples. Additionally two sets of Becker and sonic companion holes were drilled through the waste rock piles, with the Becker samples taken from a split spoon sampler and the sonic samples taken from the sonic core. The average fines content of the sonic core was found to be similar to that of the samples taken from the Becker split spoon sampler. However, the sonic drilling method resulted in significant zones of drill induced breakage and creation of rock flour in zones of dry gravel and/or cobbles within the rock pile. These drill induced breakage zones resulted in core with much higher fines content than the corresponding zones sampled from the Becker drilling. An analysis of shear strength test results on many Questa rock pile samples showed a relationship of decreasing friction angle with an increase in the percentage of fines. The higher fines contents of the Becker and sonic samples versus test pit or in situ samples needs to be considered when selecting appropriate shear strength parameters based on laboratory testing.

description: Quantum computation using continuous-time evolution under a natural hardware Hamiltonian is a promising near- and mid-term direction toward powerful quantum computing hardware. We investigate the performance of continuous-time quantum walks as a tool for finding spin glass ground states, a problem that serves as a useful model for realistic optimization problems. By performing detailed numerics, we uncover significant ways in which solving spin glass problems differs from applying quantum walks to the search problem. Importantly, unlike for the search problem, parameters such as the hopping rate of the quantum walk do not need to be set precisely for the spin glass ground state problem. Heuristic values of the hopping rate determined from the energy scales in the problem Hamiltonian are sufficient for obtaining a better than square-root scaling. This makes it practical to use quantum walks for solving such problems, and opens the door for a range of applications on suitable quantum hardware.

title: Schäden an Betonbrücken, eine nüchterne Einschätzung zwischen Besorgnis und Polemik

description: Die Frage "Was ist wirklich daran an diesen Schäden an Betonbrücken?" widerspiegelt die Besorgnis vieler, die die häufigen Berichte in den Medien aufmerksam verfolgen. Es ist in der Tat so: Die Zahl der Bauschäden insgesamt und damit auch jener an Betonbauwerken hat in den letzten Jahren zugenommen; die Tendenz ist steigend. 
Diese unbestreitbare Tatsache zieht viele negative und positive Folgen nach sich. Um einige zu nennen: Die Zahl der Bauprozesse wächst. Bausachverständige und Betonkosmetiker schießen wie Pilze aus dem Boden. Der Kunststoffindustrie ist dies recht, sieht sie doch rosigen Sanierungszeiten entgegen. Aber auch Hochschulinstitute werden von den Gerichten für Schadensaufklärung und Sanierungsvorschläge zunehmend gefordert. Daß ein so schweres Bauunglück wie der Einsturz der Berliner Kongreßhalle die Medien auf den Plan ruft, ist verständlich und richtig. Aber ansonsten erschweren sie die notwendige, nüchterne Auseinandersetzung durch bisweilen unseriöse reißerische Schlagzeilen.
Man kann jedoch der Entwicklung auch positive Seiten abgewinnen: Es entsteht eine wissenschaftlich fundierte Schadenskunde im Bauwesen. Forschung und Lehre werden befruchtet. Sachdiskussionen kommen in Gang, und der Stand der Kenntnisse wird verbreitet. Qualität gewinnt an Gewicht.
Welcher Art sind die Schäden an Betonbauwerken und insbesondere an Brücken, welche Ursachen haben sie? Wie wirken sie sich auf die ästhetische Qualität, auf die Funktionstüchtigkeit und die Standsicherheit eines Bauwerks aus? Wie mindern sie den materiellen Wert, was kostet die Schadensbehebung? Diese Fragen sind in wenigen Sätzen nicht zu beantworten. Hier wird versucht, die wesentlichen Probleme anzusprechen. Schließlich geht es nicht darum, Besorgnis zu zerstreuen, sondern um die nüchterne Einschätzung der Situation als Gegenpol zu manch polemischer Darstellung.

description: Предотвращение утечки данных было определено как процесс или решение, которое идентифицирует данные, которые являются конфиденциальными. Предотвращение утечки данных (DLP) — это метод или продукт, который пытается смягчить угрозы утечки данных. В этой работе метод кластеризации будет объединен с частотой термина или обратной частотой документа, чтобы определить правильные центроиды для анализа различных электронных писем, которые передаются между членами организации. Каждый член будет вписываться в различные тематические кластеры, и один такой тематический кластер также может состоять из нескольких членов организации, которые ранее не общались друг с другом. В работе была исследована методика кластеризации K-средних, а также предложена методика кластеризации Tabu Kдля выявления точек оптимальной кластеризации. Предложенный Tabu-КМ оптимизирует кластеризацию K-средних. Экспериментальные результаты показали, что предложенный метод обеспечивает более высокую скорость (TPR) для известного и неизвестного реципиента и более низкую ложноположительную скорость (FPR) для известного и неизвестного реципиента.

description: Deep convolutional neural networks (CNNs) show strong promise for analyzing scientific data in many domains including particle imaging detectors such as a liquid argon time projection chamber (LArTPC). Yet the high sparsity of LArTPC data challenges traditional CNNs which were designed for dense data such as photographs. A naive application of CNNs on LArTPC data results in inefficient computations and a poor scalability to large LArTPC detectors such as the Short Baseline Neutrino Program and Deep Underground Neutrino Experiment. Recently Submanifold Sparse Convolutional Networks (SSCNs) have been proposed to address this challenge. We report their performance on a 3D semantic segmentation task on simulated LArTPC samples. In comparison with standard CNNs, we observe that the computation memory and wall-time cost for inference are reduced by factor of 364 and 33 respectively without loss of accuracy. The same factors for 2D samples are found to be 93 and 3.1 respectively. Using SSCN, we present the first machine learning-based approach to the reconstruction of Michel electrons using public 3D LArTPC samples. We find a Michel electron identification efficiency of 93.9% with 96.7% of true positive rate. Reconstructed Michel electron clusters yield 95.4% in average pixel clustering efficiency and 95.5% in purity. The results are compelling to show strong promise of scalable data reconstruction technique using deep neural networks for large scale LArTPC detectors.
