This thesis explores methods for estimating 3D models using depth sensors andfinding low-rank approximations of matrices. In the first part we focus on how toestimate the movement of a depth camera and creating a 3D model of the scene.Given an accurate estimation of the camera position, we can produce dense 3Dmodels using the images obtained from the camera. We present algorithms thatare both accu

Background: We studied the efficacy and safety of mycophenolate mofetil (MMF) and tacrolimus as second-line therapy in pediatric patients with autoimmune hepatitis (AIH) who were intolerant or non-responders to standard therapy (corticosteroid and azathioprine). Patients and Methods: We performed a retrospective study of data from 13 centers in Europe, USA, and Canada. Thirty-eight patients (< 18

Serpentinite-hosted ecosystems are potential sites where life may first have evolved on Earth. Serpentinization reactions produce strongly reducing and highly alkaline fluids that are typified by high concentrations of molecular hydrogen (H2) and methane (CH4), which can be used as an energy source by chemosynthetic life. Low-temperature serpentinization at slow-spreading mid-ocean ridges provides

Central limit theorems for linear statistics of lattice random fields (including spin models) are usually proven under suitable mixing conditions or quasi-associativity. Many interesting examples of spin models do not satisfy mixing conditions, and on the other hand, it does not seem easy to show central limit theorem for local statistics via quasi-associativity. In this work, we prove general cen

Collaborative networks provide a viable means for destination management organisations (DMOs) to engage small enterprises in collaborative destination development, and may offer a means to steer destinations toward small enterprises in collaborative destination development, and may offer a means to steer destinations toward sustainability. However, the use of collaborative networks in destination

Substantial progress has been achieved in the last couple of decades in computing the electronic structure of correlated materials from first principles. This progress has been driven by parallel development in theory and numerical algorithms. Theoretical development in combining ab initio approaches and many-body methods is particularly promising. A crucial role is also played by a systematic met

Fatty acid esters of hydroxy fatty acids (FAHFAs) are a recently discovered class of endogenous lipids with antidiabetic and anti-inflammatory activities. Interest in these lipids is due to their unique biological activites and the observation that insulin-resistant people have lower palmitic acid esters of hydroxystearic acid (PAHSA) levels, suggesting that a FAHFA deficiency may contribute to me

Many animals use vision to detect, discriminate, or recognize important objects such as prey, predators, homes, or mates. These objects may differ in color and brightness-having chromatic and achromatic contrast to the background or to other objects. Visual models are powerful tools to investigate contrast detection, but need to be calibrated by experimental data to provide robust predictions. The

At many storage rings for synchrotron light production there is demand for serving both high-flux and timing users simultaneously. Today this is most commonly achieved by operating inhomogeneous fill patterns, but this is not preferable for rings that employ passive harmonic cavities to damp instabilities and increase Touschek lifetime. For these rings, inhomogeneous fill patterns could severely r

Galactoglucomannans (GGM) can be used as a precursor for the production of surfactants, plastics, hydrogels etc. However, separation of galactoglucomannan (GGM) from lignin and lignin-carbohydrate-complexes using membrane filtration is difficult. Precipitation of GGM with anti-solvents is an approach that has been previously studied. A membrane filtration step prior to precipitation is economicall

A broad measurement range of glucose is often required in clinical analysis, especially for diabetic patients where glucose levels can be very high. Pyrroloquinoline quinone glucose dehydrogenase (PQQGDH) has previously been used in electrochemical quantification of glucose with an extended linear range. However, in real sample determination of glucose, interferences from electroactive substances

Due to critical impacts of air pollution, prediction and monitoring of air quality in urban areas are important tasks. However, because of the dynamic nature and high spatio-temporal variability, prediction of the air pollutant concentrations is a complex spatio-temporal problem. Distribution of pollutant concentration is influenced by various factors such as the historical pollution data and weat

Quantitative imaging, where every pixel of an image represents a physical quantity (e.g. timeor velocity) is being increasingly used in the field of diagnostic radiology and has potential toenhance medical diagnosis. Quantitative methods for Magnetic Resonance Imaging (MRI)enables measurements of velocity and flow using a technique called Phase Contrast MagneticResonance (PC-MR), and different tim

The success of sustainable building renovation is inevitably dependent on the capabilities of the involved stakeholders throughout the entire project. Therefore, any building client with intentions of sustainable building renovations must reflect on sourcing the adequate capabilities for a sustainable renovation project. The question in focus is: how to facilitate a sourcing strategy for energy-ef

In the cyanobacterium Synechococcus sp. strain PCC 7942 a multigene family of three different isozymes encodes the proteolytic subunit ClpP of the ATP-dependent Clp protease. In contrast to the monocistronic clpPI gene, clpPII and clpPIII are part of two bicistronic operons with clpX and clpR, respectively. Unlike most bacterial Clp proteins, the Synechococcus ClpP2, ClpP3, ClpR and ClpX proteins

The Davies transformation is a method to transform the steering vector of a uniform circular array to another vector with Vandermonde form. However, this transformation can be highly sensitive to perturbations of the underlying ideal array model. In this paper, we describe a method for deriving a more robust transformation using optimisation techniques. The effectiveness of the method is illustrat
