A small number of studies have explored children's perception of speakers' voice quality and its possible influence on language comprehension. The aim of this explorative study was to investigate the relationship between the examiner's voice quality, the child's performance on a digital version of a language comprehension test, the Test for Reception of Grammar (TROG-2), and two measures of cognit
We study exciton migration in low molecular weight poly[3-(2,5-dioctylphenyl)thiophene] in dilute solution by means of ultrafast spectroscopy and Monte Carlo simulations of resonance energy transfer using the line-dipole Forster approach. The model includes the build-up of polymer chains, site-selective exciton generation, and diffusion through incoherent energy transfer. Time-resolved, ensemble-a
This experimental study examines the influence of moisture variations on the load-bearing capacity of steel-timber dowel joints. The glulam specimens used to manufacture the joints were first exposed to controlled climate changes. After being stored in the climate chambers, holes were drilled and dowels were inserted. Then, the joints were loaded to failure. The main aim of this study was to inves
This paper presents an innovative research on urban risk reduction and climate change adaptation that combines case studies, grounded theory and systems analysis, which could be used as a template for similar intersectoral and interdisciplinary investigations. Such a ‘case studies–grounded theory–systems analysis approach’ permits a grounded theory to be built from case study data, which is viewed
Benchmarking is an effective tool to compare the performance of full-scale wastewater treatment plant operation. In this study, 29 wastewater treatment plants from eight countries were surveyed with the aim of developing some key performance indicators, which may be used for benchmarking purposes. The level of utilisation of instrumentation, control and automation (ICA) has also been measured. The
Algorithms for secure encryption in a post-quantum world are currently receiving a lot of attention in the research community, including several larger projects and a standardization effort from NIST. One of the most promising algorithms is the code-based scheme called QC-MDPC, which has excellent performance and a small public key size. In this work we present a very efficient key recovery attack
Antiferromagnetic materials hold potential for use in spintronic devices with fast operation frequencies and field robustness. Despite the rapid progress in proof-of-principle functionality in recent years, there has been a notable lack of understanding of antiferromagnetic domain formation and manipulation, which translates to either incomplete or nonscalable control of the magnetic order. Here,
Popular Abstract in Swedish Vid en knäprotesoperation ersätts ledytorna i knäet med en protes gjord av metall och plast. Den vanligaste orsaken till denna operation är artros(ledsvikt. Antalet knäprotesoperationer ökar stadigt och 2009 utfördes 12,700 förstagångsoperationer i Sverige. Resultaten är överlag goda men en allvarlig komplikation som drabbar mellan 1 och 2% av patienterna är bakterieinf
Different slope algorithms can result in totally different estimates. In the worst case, this may lead to inappropriate and useless modelling estimates. A frequent lack of awareness when choosing algorithms justifies a thorough comparison of their characteristics, making it possible for researchers to select an algorithm which is optimal for their purpose. In this study, eight frequently used slop
The application of the easily available and inexpensive chromatographic matrix hydroxyapatite for reusable and reversible immobilization of enzymes for enzyme thermistor-based flow injection analysis of glucose and Urea was tested. The immobilization was achieved by simple affinity adsorption of glucose oxidase and urease by a suitable pH-induced alteration of the protein charge. A linear detectio
Popular Abstract in Swedish Dagens samhälle är allt mer beroende av elektroniska hjälpmedel så som smarta telefoner, läsplattor, datorer osv. Prestandakraven ökar i en allt högre takt och därför måste även den bakomliggande teknologin följa samma trend. De flesta av oss vill att den nya mobiltelefonen ska ha så hög kameraupplösning som möjligt men få av oss tänker på att detta medför en större mäFast and reliable data transmission together with high bandwidth efficiency are important design aspects in a modern digital communication system. Many different approaches exist but in this thesis bandwidth efficiency is obtained by increasing the data transmission rate with the faster-than-Nyquist (FTN) framework while keeping a fixed power spectral density (PSD). In FTN consecutive information
Inhaling radon and its progeny is associated with adverse health outcomes. However, previous studies of the health effects of residential exposure to radon in the United States were commonly based on a county-level temporally invariant radon model that was developed using measurements collected in the mid- to late 1980s. We developed a machine learning model to predict monthly radon concentrations
OBJECTIVES: This study sought to identify homogenous echocardiographic phenotypes in community-based cohorts and assess their association with outcomes.BACKGROUND: Asymptomatic cardiac dysfunction leads to a high risk of long-term cardiovascular morbidity and mortality; however, better echocardiographic classification of asymptomatic individuals remains a challenge.METHODS: Echocardiographic pheno
Parser generators are an indispensable tool for rapid language devel- opment. However, they often fall short of the finesse of a hand-crafted parser, built with the language semantics in mind. One area where generated parsers have pro- vided unsatisfactory results is that of error recovery. Good error recovery is both natural, giving recovery suggestions in line with the intention of the programme
