We present the methods for phenotype evaluation, which give good chances to identify taxa larger according to the anatomical and morphological features. The basic idea is to evaluate characters having regard to completeness and reproducibility. We composed a list of about 100 basic characters and propose standardized ways of measuring them. We also present a list of morphological and anatomical te
A design study of a horizontal neutron reflectometer adapted to the general baseline of the long pulse European Spallation Source (ESS) is presented. The instrument layout comprises advanced solutions for the neutron guide, high-resolution pulse shaping and beam bending onto a sample surface being thoroughly adjusted to the properties of the ESS. The length of this instrument is roughly 55 m, enab
Spectral estimation is an important classical problem that has received considerable attention in the signal processing literature. In this contribution, we propose a novel method for estimating the parameters of sums of complex exponentials embedded in additive noise from regularly or irregularly spaced samples. The method relies on Kronecker's theorem for Hankel operators, which enables us to fo
We report on the production and characterization of polymer-based ultra-thin (sub 10 nm) foils suited for experiments on laser-ion acceleration in the regime of radiation pressure acceleration. Beside the remarkable mechanical stability compared with commonly used diamond-like-carbon foils, a very homogeneous layer thickness and a small surface roughness have been achieved. We describe the technic
OBJECTIVE-To develop a model for the prediction of type 2 diabetes mellitus (T2DM) risk on the basis of a multivariate logistic model and 1-h plasma glucose concentration (1-h PG). RESEARCH DESIGN AND METHODS-The model was developed in a cohort of 1,562 non-diabetic subjects from the San Antonio Heart Study (SAHS) and validated in 2,395 nondiabetic subjects in the Botnia Study. A risk score on the
A novel method for QRST cancellation during atrial fibrillation (AF) is introduced for use in recordings with two or more leads. The method is based on an echo state neural network which estimates the time-varying, nonlinear transfer function between two leads, one lead with atrial activity and another lead without, for the purpose of canceling ventricular activity. The network has different sets
Measurements with unknown time delays are common in different applications such as microphone array, radio antenna array calibration, where the sources (e.g. sounds) are transmitted in unknown time instants. In this paper, we present a method for estimating unknown time delays from Time-Difference-of-Arrival (TDOA) measurements. We propose a novel rank constraint on a matrix depending on the measu
1. Permutation tests are important in ecology and evolution as they enable robust analysis of small sample sizes and control for various forms of dependencies among observations. A common source of dependence is spatial autocorrelation. Accounting for spatial autocorrelation is often crucial, because many ecological and evolutionary processes are spatially restricted, such as gene flow, dispersal,
Poly-3-d-hydroxybutyrate (PHB) is a promising biopolymer naturally produced by several bacterial species. In the present study, the robust baker's yeast Saccharomyces cerevisiae was engineered to produce PHB from xylose, the main pentose found in lignocellulosic biomass. The PHB pathway genes from the well-characterized PHB producer Cupriavidus necator were introduced in recombinant S. cerevisiae
With the transistor being the workhorse in modern electronics it has been vastly improved since its invention. However, the previous go-to improvement method of scaling it down has reached a dead end. Power dissipation has become a large concern and is in need of a solution. In the pursuit of further improving the transistor structure and its performance new approaches are being evaluated. A very
Automated manufacturing processes are an important component of today’s industries. Assuming the processes are properly maintained they allow for great efficiency when producing various goods. Image analysis can be used as a tool to monitor such processes and evaluate their results. This Thesis treats development of algorithms for automatic evaluation of images acquired using a standardized proce
Problem definition Additive manufacturing is a technology that has received a lot of attention and many are wondering how it will affect them plastic industry in the future. Additive manufacturing is mostly used for prototyping today but there is reason to believe that the technology has potential to overtake other application areas for plastic or used as a complementary method to existing manufac
This thesis work is part of a larger project with final goal to be able to measure the oxygen concentration in the lungs of infants, using non-invasive laser spectroscopy. This thesis is specifically dealing with simulations of light transport through the upper body of infants, as well as constructing a tissue-like model (phantom) that can be used in experiments. The goal is to use these simulatio
Bakgrund: Att vara förälder till barn med funktionsnedsättning innebär ofta ökade stressfaktorer i vardagen med de ökade behov barnet har. Stress, ångest och depression är vanligt förekommande samt bortprioritering av meningsfulla aktiviteter, vilket kan leda till aktivitetsobalans. Syfte: Syftet med studien var att i vetenskapliga studier undersöka interventioner för föräldrar till barn med funkt
Bakgrund: Stroke är en vanlig orsak till att vuxna människor drabbas av fysiska och kognitiva funktionsnedsättningar. Kognition är individens förmåga ta in, tolka och bearbeta information från omgivningen. Att inte klara av att utföra vardagliga aktiviteter så som personlig vård, arbete och fritidsaktiviteter är en vanlig följd av kognitiva funktionsnedsättningar. Syfte: studien har ett tvådelat s
Rehabilitering efter en stroke är viktig för att den drabbade individen ska återfå så stor del av de påverkade kroppsfunktionerna som möjligt. Balansen blir ofta försämrad hos individer som överlevt stroke och behöver stärkas för att inte hindra individen i dennes vardagliga liv. Rehabiliteringsträningen av balansen bör innehålla motivationsfaktorer för att träningen ska ske i tillräckligt stor omThe rehabilitation after a stroke is important for the individual so that the affected body functions recover as much as possible. The balance is often impaired after a stroke and need to be strengthend to not impede the stroke-survivor in the daily life. The rehabilitation training of the balance should include motivation factors for the training to take place in sufficiently large scale. The aim
I Sverige är höghastighetsjärnvägar ett debatterat ämne. Undersökningsarbeten har startat för det första steget i ett höghastighetsnät – Ostlänken mellan Järna och Linköping – som planeras vara trafikerad år 2028. Höghastighetsjärnvägen är avsedd att tillåta hastigheter på 320 km/h. Vid så höga hastigheter blir dimensioneringskraven för brobanans vibrationer strängare. Tidigare studier har visat aIn Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. At such speeds, the design requirements of the accelerations of the bridge superstructure become more s
