Computational single-image high dynamic range imaging
Creators: name: Rouf, Mushfiqur
Publisher: name: University of British Columbia
Year: 2018

description: This thesis proposes solutions for increasing the dynamic range (DR)—the number of intensity levels—of a single image captured by a camera with a standard dynamic range (SDR). The DR in a natural scene is usually too high for SDR cameras to capture, even with optimum exposure settings. The intensity values of bright objects (highlights) that are above the maximum exposure capacity get clipped due to sensor over-exposure, while objects that are too dark (shades) appear dark and noisy in the image. Capturing a high number of intensity levels would solve this problem, but this is costly, as it requires the use of a camera with a high dynamic range (HDR). Reconstructing an HDR image from a single SDR image is difficult, if not impossible, to achieve for all imaging situations. For some situations, however, it is possible to restore the scene details, using computational imaging techniques. We investigate three such cases, which also occur commonly in imaging. These cases pose relaxed and well-posed versions of the general single-image high dynamic range imaging (HDRI) problem. The first case occurs when the scene has highlights that occupy a small number of pixels in the image; for example, night scenes. We propose the use of a cross-screen filter, installed at the lens aperture, to spread a small part of the light from the highlights across the rest of the image. In post-processing, we detect the spread-out brightness and use this information to reconstruct the clipped highlights. Second, we investigate the cases when highlights occupy a large part of the scene. The first method is not applicable here. Instead, we propose to apply a spatial filter at the sensor that locally varies the DR of the sensor. In post-processing, we reconstruct an HDR image. The third case occurs when the clipped parts of the image are not white but have a color. In such cases, we restore the missing image details in the clipped color channels by analyzing the scene information available in other color channels in the captured image. For each method, we obtain a maximum-a-posteriori estimate of the unknown HDR image by analyzing and inverting the forward imaging process.

description: Water Safety Plans (WSPs) are a management tool to identify and prioritize risks and implement appropriate control measures throughout the water supply chain, from catchment to consumer. WSPs have been implemented in over 90 countries; yet, costs, benefits and the enabling environment elements necessary for WSP implementation are under-studied. To better understand these factors, we conducted interviews with WSP implementation management teams from 20 private urban water utilities in China, Cuba, France, Morocco and Spain in 2014. Collectively, these utilities serve 10.6 million consumers and supply over 2.2 million m3/day of water to consumers. Time for WSP implementation to achieve certification averaged 13 months. The main startup cost was staff time, averaging 16.2 full-time equivalent person-months. Additional costs, averaging €16,777, were for training staff, hiring consultants, purchasing equipment, and certifying WSPs. Benefits commonly reported included improved hazard control, treatment practices, record keeping, and client and health agency confidence.

description: This work reports the results achieved by the optimization of the CAP applied to cement plants for CO2 capture. A set of operating environments typical for the cement industry in Europe has served as the basis for the CAP optimization. The primary energy consumption per unit of avoided CO2 emissions has been applied as the objective function. The design of the absorption columns of the CAP has been performed taking into account the results of the pilot plant tests carried out at GE facilities in Växjö (Sweden) for cement plant-like flue gas conditions, and the CAP simulations have been adapted accordingly to implement and reproduce the experimental findings of the pilot tests. The CAP performance is assessed, providing the required input for the integration of the CAP with the cement plant. Mass and heat balances for each optimized case are shown, providing stream tables and the equipment energy consumptions. The sets of operating conditions minimizing the energy consumption of the capture process for each case are in agreement with the differences in the assumed environment. The resulting trends for the optimized energy consumption are in line with the theoretical expectation that higher CO2 concentrations in the flue gas enable a lower energy penalty for CO2 capture. Consequently, the results confirm the CAP’s potential for highly efficient CO2 capture from cement plants.

description: Medical imaging has become an increasingly important tool in screening, diagnosis, prognosis, and treatment of various diseases given its information visualization and quantitative assessment. The aim of this paper is to develop a Bayesian scalar-on-image regression model to integrate high-dimensional imaging data and clinical data to predict cognitive, behavioral, or emotional outcomes, while allowing for non-ignorable missing outcomes. Such an non-ignorable non-response consideration is motivated by examining the association between baseline characteristics and cognitive abilities for 802 Alzheimer patients enrolled in the Alzheimer’s Disease Neuroimaging Initiative 1 (ADNI1), for which data are partially missing. Ignoring such missing data may distort the accuracy of statistical inference and provoke misleading results. To address this issue, we propose an imaging exponential tilting model to delineate the data missing mechanism and incorporate an instrumental variable to facilitate model identifiability followed by a Bayesian framework with Markov chain Monte Carlo algorithms to conduct statistical inference. This approach is validated in simulation studies where both the finite sample performance and asymptotic properties are evaluated and compared with the model with fully observed data and that with a misspecified ignorable missing mechanism. Our proposed methods are finally carried out on the ADNI1 dataset, which turns out to capture both of those clinical risk factors and imaging regions consistent with the existing literature that exhibits clinical significance.

description: A fundamental challenge in observational causal inference is that assumptions about unconfoundedness are not testable from data. Assessing sensitivity to such assumptions is therefore important in practice. Unfortunately, some existing sensitivity analysis approaches inadvertently impose restrictions that are at odds with modern causal inference methods, which emphasize flexible models for observed data. To address this issue, we propose a framework that allows (1) flexible models for the observed data and (2) clean separation of the identified and unidentified parts of the sensitivity model. Our framework extends an approach from the missing data literature, known as Tukey’s factorization, to the causal inference setting. Under this factorization, we can represent the distributions of unobserved potential outcomes in terms of unidentified selection functions that posit a relationship between treatment assignment and unobserved potential outcomes. The sensitivity parameters in this framework are easily interpreted, and we provide heuristics for calibrating these parameters against observable quantities. We demonstrate the flexibility of this approach in two examples, where we estimate both average treatment effects and quantile treatment effects using Bayesian nonparametric models for the observed data.

description: We give a direct microscopic derivation of the F-theory background that corresponds to four D7 branes of type I' theory by taking into account the D-instanton contributions to the emission of the axio-dilaton field in the directions transverse to the D7's. The couplings of the axio-dilaton to the D-instanton moduli modify its classical source terms which are shown to be proportional to the elements of the D7 brane chiral ring. Solving the bulk field equations with the non-perturbatively corrected sources yields the full F-theory background. This solution represents the gravitational dual of the four-dimensional theory living on a probe D3 brane of type I', namely of the N=2, Sp(1) SYM theory with Nf=4. Our results provide an explicit microscopic derivation of the non-perturbative gravitational dual of this theory. They also explain the recent observation that the exact coupling for this theory can be entirely reconstructed from its perturbative part plus the knowledge of the chiral ring on the D7 branes supporting its flavor degrees of freedom.

description: The paper presents an experimental study on the preparation and characterization of cellulose films and their use for reactive lignosulfonate extraction. The extraction of lignosulfonates leads to emulsion and crud formation when standard equipment is applied. By using cellulose films as a support layer between the aqueous feed phase and the organic extractant phase, emulsion formation is prevented. The results showed that selective separation and a fractionation of the lignosulfonates can be realized with this novel approach simultaneously.

Dual-loop linear controller for LLC resonant converters
Creators: name: Degioanni, Franco
Publisher: name: University of British Columbia
Year: 2018

description: For the last years, LLC resonant converters have gained wide popularity in a large number of domestic and industrial applications due to their high-efficiency and power density. Common applications of this converter are battery chargers and high efficiency power supplies, which require tight output voltage regulation. In traditional PWM converters, closed-loop controllers based on small-signal models are typically implemented to achieve zero steady-state error and minimize the effects of disturbances at the output. However, traditional averaging techniques employed in PWM converters cannot be applied to LLC's and highly complex mathematical models are required. As a consequence, designing linear controllers for this type of converter is usually based on empirical methods, which require high-cost equipment and do not provide any physical insight into the system. The implementation of current-mode controllers has been vastly developed for PWM converters. Employing an inner current loop and outer voltage loop has shown numerous advantages, such as, tight current regulation, over-current protection, and ample bandwidth. However, this control architecture is not commonly implemented in LLC resonant converters, and conventional single voltage loop controllers are employed. This work proposes a simple and straightforward methodology for designing linear controllers for LLC resonant converters. A simplified second order equivalent circuit is developed and employed to derive all the relevant equations for designing proper compensators. A dual-loop control scheme including an inner current loop and outer voltage loop is proposed. The implementation of the dual-loop configuration provides improved closed-loop performance for the entire operational range. The theoretical findings are supported by detailed mathematical procedures and validated by simulation and experimental results.

description: We propose a method for constructing Yukawa terms for noncommutative SO(10) and E6 GUTs, when these GUTs are formulated within the enveloping-algebra formalism. The most general noncommutative Yukawa term that we propose contains, at first order in thetamunu, the most general BRS invariant Yukawa contribution whose only dimensionful parameter is the noncommutativity parameter. This noncommutative Yukawa interaction is thus renormalisable at first order in thetamunu.

description: We investigate a composite elastic meta-slab with exceptional transmission properties, particularly the presence of a W-shaped bandgap. A comprehensive study, utilizing experimental measurements, the finite element method, and an analytical approach, identifies this specific bandgap. The meta-slab design involves cutting an array of composite materials arranged in parallel with strategically placed incisions. This configuration ensures that the materials between the slits act as plate-like waveguides within the surrounding medium. The incorporation of steel into ABS-based Fabry-Perot cavities induces a notable coupling effect between longitudinal waves and localized modes traversing the structure, leading to the formation of two distinct Fabry-Perot resonators. These coupling effects generate a series of resonances and antiresonances, ultimately producing the W-band gap through the interaction of two symmetric Fano resonances.

description: We report a first attempt to produce metastable hcp solid helium below its melting pressure. A focused sound pulse is emitted along the c-axis of a mono-domain hcp helium-4 crystal starting from a static pressure just above the melting pressure. The sound pulse is made as simple as possible with one negative and one positive swing only. Density at focus is monitored by an optical interferometric method. Performed numerical simulations show that the crystal anisotropy splits the focused wave into two separate pulses, corresponding to a longitudinal wave along the c-axis and a radial one perpendicular to it. The amplification factor due to focusing remains nevertheless important. Negative pressure swings up to 0.9 bar have been produced, crossing the static melting pressure limit. Improvements in the detection method and in the focusing amplification are proposed.

description: Interferometric imaging is a well established method to image phase objects by mixing the image wavefront with a reference one on a CCD camera. It has also been applied to fast transient phenomena, mostly through the analysis of single interferograms. It is shown that for repetitive phenomena multiphase acquisition brings significant advantages. A 1 MHz focused sound field emitted by a hemispherical piezotransducer in water is imaged as an example. Quantitative image analysis provides high resolution sound field profiles. Pressure at focus determined by this method agrees with measurements from a fiber-optic probe hydrophone. This confirms that multiphase interferometric imaging can indeed provide quantitative measurements.

description: This article introduces a machine for sampling approximate model-X knockoffs for arbitrary and unspecified data distributions using deep generative models. The main idea is to iteratively refine a knockoff sampling mechanism until a criterion measuring the validity of the produced knockoffs is optimized; this criterion is inspired by the popular maximum mean discrepancy in machine learning and can be thought of as measuring the distance to pairwise exchangeability between original and knockoff features. By building upon the existing model-X framework, we thus obtain a flexible and model-free statistical tool to perform controlled variable selection. Extensive numerical experiments and quantitative tests confirm the generality, effectiveness, and power of our deep knockoff machines. Finally, we apply this new method to a real study of mutations linked to changes in drug resistance in the human immunodeficiency virus. Supplementary materials for this article are available online.

description: Time-varying networks are fast emerging in a wide range of scientific and business applications. Most existing dynamic network models are limited to a single-subject and discrete-time setting. In this article, we propose a mixed-effect network model that characterizes the continuous time-varying behavior of the network at the population level, meanwhile taking into account both the individual subject variability as well as the prior module information. We develop a multi-step optimization procedure for a constrained likelihood estimation, and derive the associated asymptotic properties. We demonstrate the effectiveness of our method through both simulations and an application to a study of brain development in youth.
Alone but not lonely? distinct types, antecedents, and correlates of older and younger adults' daily life solitude experiences in two cultural contexts
Creators: name: Lay, Jennifer Christina
Publisher: name: University of British Columbia
Year: 2018

description: Solitude (the absence of social interaction, whether in-person or electronic) is a ubiquitous yet understudied experience, often confused with loneliness, but sometimes sought out in daily life. This research program aimed to better understand the negative and positive aspects of solitude, drawing on data from three samples: 50 university students in Vancouver, 100 community-dwelling adults aged 50+ in Vancouver (including 51% East Asian immigrants), and 56 community-dwelling adults aged 50+ in Hong Kong. Participants completed approximately 30 repeated daily life assessments over 10 days on their current thoughts, affect, location, activities, social situation, and desire for solitude. Study 1 used latent profile analysis to identify distinct types of solitude experiences from the everyday thought-affect patterns of younger and middle-aged/older adults in Vancouver, and examined for whom and under what circumstances solitude may have positive or negative connotations. Two distinct types of solitude experiences were identified. Overall desire for solitude and social self-efficacy were associated with positive solitude experiences, and self-rumination and self-reflection with negative solitude experiences. Study 2 specifically examined solitude desire and its location and affective correlates among middle-aged and older adults living in Vancouver. At most occasions, solitude happened by individuals’ own choosing. Older adults were more likely to go to locations that matched their desired social context, and solitude-seeking had less negative affective associations for them as compared to middle-aged adults. East/Southeast Asian participants reported more loneliness than European/North American participants. Study 3 combined two data sets, from Vancouver and Hong Kong, to disentangle the roles of culture, immigration, and acculturation on solitude-loneliness associations among adults aged 50+. Participants high in acculturation to the local (host) culture or who desired solitude at that moment showed no association between being in solitude and feeling lonely. Taken together, these studies show that solitude and loneliness are distinct constructs with different predictors, correlates, and consequences. This research identified key individual difference, life phase, and social contextual factors associated with seeking solitude and thriving during solitude.

description: Between the different calciner configurations, described in D8.1, the in-line calciner is the best option for the operation in oxyfuel mode. A few considerations are reported to confirm that the calciner rig in Stuttgart University represents quite closely the industrial situation both in air calcination mode and in oxyfuel mode; the same for the difficult task to measure real values of temperature, inevitably biased by radiant heat, because it is possible to assume that similar deviations are included in the industrial measured values; the difference between the real temperature value and the measured one should not be higher than 40 °C. Consequently it is possible to consider the results obtained by the tests done in work package WP8 in different conditions as meaningful and useful to supply quantitative information to be used in the mathematical model developed in WP6. Effects on calcination degree consequent to temperature, residence time, CO2 concentration, raw meal fineness, water vapor have been evaluated. The main finding is that decarbonation takes place in an oxyfuel mode at temperatures that are higher than those registered for air calcination: the difference is in the order of 50 °C, and the temperature absolute value of calcination in oxyfuel mode is evaluated to be around 920 °C. This value is critical from the technological point of view and may be a possible cause of anomalous coatings. This aspect can’t be analyzed with the available equipment and will be matter of studies during future full scale tests. The other parameters have also influence on the calcination process but all of them need the support of temperature to reach an acceptable degree of calcination.

description: Plasmodium of \emph{Physarum polycephalum} is a single cell visible by unaided eye. On a non-nutrient substrate the plasmodium propagates as a traveling localization, as a compact wave-fragment of protoplasm. The plasmodium-localization travels in its originally predetermined direction for a substantial period of time even when no gradient of chemo-attractants is present. We utilize this property of \emph{Physarum} localizations to design a two-input two-output Boolean logic gates $ \to $ and $ \to $. We verify the designs in laboratory experiments and computer simulations. We cascade the logical gates into one-bit half-adder and simulate its functionality.

description: The article considers the problem of estimating a high-dimensional sparse parameter in the presence of side information that encodes the sparsity structure. We develop a general framework that involves first using an auxiliary sequence to capture the side information, and then incorporating the auxiliary sequence in inference to reduce the estimation risk. The proposed method, which carries out adaptive Stein’s unbiased risk estimate-thresholding using side information (ASUS), is shown to have robust performance and enjoy optimality properties. We develop new theories to characterize regimes in which ASUS far outperforms competitive shrinkage estimators, and establish precise conditions under which ASUS is asymptotically optimal. Simulation studies are conducted to show that ASUS substantially improves the performance of existing methods in many settings. The methodology is applied for analysis of data from single cell virology studies and microarray time course experiments. Supplementary materials for this article are available online.

description: Ams: We study the 12C/13C isotopic ratio in the disk of the central molecular zone and in the halo to trace gas accretion toward the Galactic center region in the Milky Way. Methods: Using the IRAM 30m telescope, we observe the J=1-0 rotational transition of HCO+, HCN, HNC and their 13C isotopic substitutions in order to measure the 12C/13C isotopic ratio. We observe 9 positions selected throughout the Galactic center region, including clouds at high latitude; locations where the X1 and X2 orbits associated with the barred potential are expected to intersect; and typical Galactic center molecular clouds. Results: We find a systematically higher 12C/13C isotopic ratio (>40) toward the halo and the X1 orbits than for the Galactic center molecular clouds (20-25). Our results point out to molecular gas which has undergone a different degree of nuclear processing than that observed in the gas towards the inner Galactic center region. Conclusions: The high isotopic ratios are consistent with the accretion of the gas from the halo and from the outskirts of the Galactic disk.

We focus on a scalar-tensor extension of k-inflation coupled to matter for which we derive a modified Mukhanov-Sasaki equation for the curvature perturbation. Significant corrections to the power spectrum appear when the coupling function changes abruptly along the inflationary trajectory. This gives rise to a modification of Starobinsky's model of perturbation features. We analyse the way the power spectrum is altered in the infrared when such features are present.

description: It is an unmistakable fact that objects hold an important role in the construction of identity, acting as markers of a certain lifestyle. In this process of symbolic construction, to own a certain object entails more often than not a high social status.

However, some objects can also carry with them stigma: owning them brings about a discrediting effect in the construction of the owner's identity.

For people with disabilities the use of objects employed for mitigate their impairment (as a wheelchair or a walking aid) often act as a symbol of stigma and empathize the prejudices to the people who use them.

description: We combine the GALFORM semi-analytical model of galaxy formation, which predicts the star formation and merger histories of galaxies, the GRASIL spectro-photometric code, which calculates the spectral energy distributions (SEDs) of galaxies self-consistently including reprocessing of radiation by dust, and artificial neural networks (ANN), to investigate the clustering properties of galaxies selected by their emission at submillimetre wavelengths (SMGs). We use the Millennium Simulation to predict the spatial and angular distribution of SMGs. At redshift z = 2, we find that these galaxies are strongly clustered, with a comoving correlation length of r0 = 5.6 \pm 0.9 Mpc/h for galaxies with 850μm flux densities brighter than 5 mJy, in agreement with observations. We predict that at higher redshifts these galaxies trace denser and increasingly rarer regions of the universe. We present the predicted dependence of the clustering on luminosity, submillimetre colour, halo and total stellar masses. Interestingly, we predict tight relations between correlation length and halo and stellar masses, independent of sub-mm luminosity.

description: AudioSet is one of the most used and largest datasets in audio tagging, containing about 2 million audio samples that are manually labeled with 527 event categories organized into an ontology. However, the annotations contain inconsistencies, particularly where categories that should be labeled as positive according to the ontology are frequently mislabeled as negative. To address this issue, we apply Hierarchical Label Propagation (HLP), which propagates labels up the ontology hierarchy, resulting in a mean increase in positive labels per audio clip from 1.98 to 2.39 and affecting 109 out of the 527 classes. Our results demonstrate that HLP provides performance benefits across various model architectures, including convolutional neural networks (PANN's CNN6 and ConvNeXT) and transformers (PaSST), with smaller models showing more improvements. Finally, on FSD50K, another widely used dataset, models trained on AudioSet with HLP consistently outperformed those trained without HLP. Our source code will be made available on GitHub.

description: The article considers the problem of estimating a high-dimensional sparse parameter in the presence of side information that encodes the sparsity structure. We develop a general framework that involves first using an auxiliary sequence to capture the side information, and then incorporating the auxiliary sequence in inference to reduce the estimation risk. The proposed method, which carries out adaptive SURE-thresholding using side information (ASUS), is shown to have robust performance and enjoy optimality properties. We develop new theories to characterize regimes in which ASUS far outperforms competitive shrinkage estimators, and establish precise conditions under which ASUS is asymptotically optimal. Simulation studies are conducted to show that ASUS substantially improves the performance of existing methods in many settings. The methodology is applied for analysis of data from single cell virology studies and microarray time course experiments.

description: We demonstrate that freeing a single-atom thick layer of hexagonal boron nitride (hbn) from tight chemical bonding to a Ni(111) thin film grown on a W(110) substrate can be achieved by intercalation of Au atoms into the interface. This process has been systematically investigated using angle-resolved photoemission spectroscopy, X-ray photoemission and absorption techniques. It has been demonstrated that the transition of the hbn layer from the "rigid" into the "quasi-freestanding" state is accompanied by a change of its lattice constant. Using chemical vapor deposition, graphene has been successfully synthesized on the insulating, quasi-freestanding hbn monolayer. We anticipate that the in situ synthesized weakly interacting graphene/hbn double layered system could be further developed for technological applications and may provide perspectives for further inquiry into the unusual electronic properties of graphene.

description: Many scientific and engineering challenges—ranging from pharmacokinetic drug dosage allocation and personalized medicine to marketing mix (4Ps) recommendations—require an understanding of the unobserved heterogeneity to develop the best decision making-processes. In this article, we develop a hypothesis test and the corresponding p-value for testing for the significance of the homogeneous structure in linear mixed models. A robust matching moment construction is used for creating a test that adapts to the size of the model sparsity. When unobserved heterogeneity at a cluster level is constant, we show that our test is both consistent and unbiased even when the dimension of the model is extremely high. Our theoretical results rely on a new family of adaptive sparse estimators of the fixed effects that do not require consistent estimation of the random effects. Moreover, our inference results do not require consistent model selection. We showcase that moment matching can be extended to nonlinear mixed effects models and to generalized linear mixed effects models. In numerical and real data experiments, we find that the developed method is extremely accurate, that it adapts to the size of the underlying model and is decidedly powerful in the presence of irrelevant covariates. Supplementary materials for this article are available online.

description: Kinematical models are constrained by the latest observational data from geometry-distance measurements, which include 557 type Ia supernovae (SNIa) Union2 data and 15 observational Hubble data. Considering two parameterized deceleration parameter, the values of current deceleration parameter $q_{0}$, jerk parameter $j_{0}$ and transition redshift $z_{T}$, are obtained. Furthermore, we show the departures for two parameterized kinematical models from $Λ$CDM model according to the evolutions of jerk parameter $j(z)$. Also, it is shown that the constraint on jerk parameter $j(z)$ is weak by the current geometrical observed data.

description: We present measurements of B+ -> Dbar*0 tau+ nu_tau and B+ -> Dbar^0 tau+ nu_tau decays in a data sample of 657 x 10^6 BBbar pairs collected with the Belle detector at the KEKB asymmetric-energy e+e- collider. We find 446^{+58}_{-56} events of the decay B+ -> Dbar*0 tau+ nu_tau with a significance of 8.1 standard deviations, and 146^{+42}_{-41} events of the decay B+ -> Dbar0 tau+ nu_tau with a significance of 3.5 standard deviations. The latter signal provides the first evidence for this decay mode. The measured branching fractions are B(B+ -> Dbar*0 tau+ nu_tau)=(2.12^{+0.28}_{-0.27} (stat) +- 0.29 (syst)) % and B(B+ -> Dbar0 tau+ nu_tau)=(0.77 +- 0.22 (stat) +- 0.12 (syst)) %.
