Temporal rainfall disaggregration based on scaling properties

The present study concerns disaggregation of daily rainfall time series into higher resolution. For this purpose, the scaling-based cascade model proposed by Olsson (1998) is employed. This model operates by dividing each rainy time period into halves of equal length and distributing the rainfall volume between the halves. For this distribution three possible cases are defined, and the occurrence

Multifractal properties of daily rainfall in two different climates

The multifractal properties of daily rainfall were investigated in two contrasting climates: an east Asian monsoon climate (China) with an extreme rainfall variability and a temperate climate (Sweden) with a moderate rainfall variability. First, daily time series were studied. The results showed that daily rainfall in both climates can be viewed as the result of a multiplicative cascade process fo

Glued-In Rods for Timber Structures - Development of a Calculation Model

This report relates to GIROD WP1 – “Development of a calculation model”. WP1 consists of four sub-WPs: 1.1 “Theoretical work”, 1.2 “Bond line tests”, 1.3 “Tests for calibration” and 1.4 “Calibration of model”.In WP1.1 theoretical models for rational prediction of pull out strength have been developed. The models include a very simple ideal plastic model, a linear elastic fracture mechanics model,

Mechanics of Paperboard Packages : Performance at Short Term Static Loading

Paper 1Several problems emerge when a paperboard package is modeled by means of the nite element method. One of the issues that one has to deal with is the constitutive model of the paperboard. Paperboard and paper in general areorthotropic materials, which means that constitutive parameters in three orthogonal directions must be determined. Furthermore, the geometry of papersheets makes it dicult

Finite Element Analysis of Structure-acoustic Systems : Methods and Applications

Paper 1The problem in which a flexible structure interacts with an acoustic fluid is analysed by use of the finite element method. With increasing complexity of the geometry and when increasing the frequency limit is of interest, the number of degrees of freedom needed to describe the system becomes very large. To reduce the coupled system, modal analysis is performed in the structural and in the

Unravelling the structure and dynamics of lipid nanoparticles for biomolecule delivery

Encapsulation in self-assembled lipid structures has been shown to increase the stability of large biomolecules, including proteins and nucleic acids (NAs), which has many potential applications in the food and pharmaceutical industries. In order to fully optimise the encapsulation system for a certain application, however, it is important to understand the effect of the encapsulated biomolecule o

Hybrid Quantized Signal Detection with a Bandwidth-Constrained Distributed Radar System

This paper addresses the hybrid quantized signal detection problem in a distributed radar system, where widely separated antennas transmit low-bit quantized data with varying quantization levels depending on the different bandwidth constraint for each channel to a fusion center. To enable a high detection performance with such hybrid quantized data, we formulate the generalized likelihood ratio, R

Preoperative circulating tumor DNA level is associated to poor overall survival in patients with ovarian cancer

Introduction/BackgroundCirculating tumor DNA (ctDNA), which is shed from tumor cells into the blood, is a promising minimal-invasive method for cancer diagnostics and monitoring. The aim of this study was to evaluate preoperative ctDNA levels in the plasma of patients with ovarian cancer and correlate the levels to clinico-pathological parameters and patient outcome.MethodologyTumor DNA was extrac

Comparison of disease severity in glaucoma patients identified by screening in the 1990s and in routine clinical care in the 2010s in Sweden

Background and PurposeIn a previous study comparing the amount of visual field damage at presentation in patients having open-angle glaucoma (OAG) identified through screening and in patients diagnosed in routine clinical practice in the 1990s, the damage was considerably worse in the clinically diagnosed patients. In the present study we compare visual field damage at presentation in the same 402

Navigating Family Reunification for Third Country Nationals: An Analyse of the Impact of Waiting Period Requirements on the Right to Family Life under ECHR and EU Law

The present thesis explores the requirement of the waiting period to grant family reunification to Third Country Nationals from the perspective of human rights law. It examines how this requirement, which currently forms a significant part of immigration policies within European member states, may impact TCNs' Right to family life under the European Convention on Human Rights (ECHR) and EU

Predictors of diagnostic conversion from major depression to bipolar disorder : A Swedish national longitudinal study

Background It is clinically important to predict the conversion of major depression (MD) to bipolar disorder (BD). Therefore, we sought to identify related conversion rates and risk factors. Methods This cohort study included the Swedish population born from 1941 onward. Data were collected from Swedish population-based registers. Potential risk factors, including family genetic risk scores (FGRS)

Statistical properties of aftershock rate decay : Implications for the assessment of continuing activity

Aftershock rates seem to follow a power law decay, but the assessment of the aftershock frequency immediately after an earthquake, as well as during the evolution of a seismic excitation remains a demand for the imminent seismic hazard. The purpose of this work is to study the temporal distribution of triggered earthquakes in short time scales following a strong event, and thus a multiple seismic

A European Dashboard showcasing the State of the Environment

The European Open Science Cloud is a pan-European initiative that aims at developing a federated infrastructure that supports scientific research and Open Science. Having the FAIR principles at the core of Open Science practices, the Environmental Research Infrastructures (ENVRIs) that operate in Europe collaborate at cluster level (the ENVRI cluster) continuously improving the FAIRness of their s

Moonlighting Behavior among Migrants : Determinants and Implications for Wellbeing in South Africa

Notwithstanding the wealth of research on migration and subjective wellbeing, the issue of moonlighting and its welfare implication among migrants has not been thoroughly explored in empirical literature. Using rich individual-level panel data from the University of Cape Town’s National Income Dynamics Study (NIDS), this study established a number of interesting findings: (a) there is moonlighting
