A tree t-spanner T of a graph G is a spanning tree of G whose max-stretch is t, i.e., the distance between any two vertices in T is at most t times their distance in G. If G has a tree t-spanner but not a tree (t - 1)-spanner, then G is said to have max-stretch of t. In this paper, we study the Max-Stretch Reduction Problem: for an unweighted graph G = (V, E), find a set of edges not in E original
A tree t-spanner T of a graph G is a spanning tree of G whose max-stretch is t, i.e., the distance between any two vertices in T is at most t times their distance in G. If G has a tree t-spanner but not a tree (t−1)-spanner, then G is said to have max-stretch of t. In this paper, we study the Max-Stretch Reduction Problem: for an unweighted graph G=(V,E), find a set of edges not in E originally wh
In this paper, we present and discuss results from an investigation of verb placement in modern Faroese in which we collected data from speakers from a number of different dialect areas in the Faroe Islands. Altogether we interviewed 54 informants (age 15 – 67, 29 women and 25 men). Therefore, our study not only investigates the geographical variation claimed to be present in Faroese with respect
Sediments from the small lake Ilsø situated in the Illerup/Alken Enge Valley were studied in order to investigate past landscape development at the time of a probably ritual human mass burial following battle during the Roman Iron Age (ad 1–400). A pollen record from Ilsø and a number of other records from Jutland were combined using the Landscape Reconstruction Algorithm to reconstruct local vege
Somatic mosaicism, the presence of genetically distinct cells within an organism, has been increasingly associated with human morbidity, ranging from being a cause of rare syndromes to a risk factor for common disorders such as malignancy and cardiovascular disease. Previous studies interrogating the normal prevalence of somatic mosaicism have focused on adults. We here present an estimate of the
Idiopathic Scoliosis is a spinal deformity affecting approximately 3% of otherwise healthy children or adolescents. The etiology is still largely unknown but has an important genetic component. Genome-wide association studies (GWAS) have identified a number of common genetic variants that are significantly associated with idiopathic scoliosis in Asian and Caucasian populations, rs11190870 close to
In this paper we analyze the effects of body shadowing in multiple-input-multiple-output (MIMO) channels used for personal area networks (PANs). We give physical reasoning to why PANs may experience two different types of shadowing, and to support our argument, we present results from a measurement campaign for three different PAN channels with human influence. The campaign is performed using diff
The number of connected IoT devices increases rapidly and so do cyber threats against them. In contrast to high-end computers, IoT devices are extra vulnerable to threats since they many times don’t have the same defense mechanisms because of their limited resources. Intrusion detection systems (IDS) are typically used to monitor IoT devices externally on a server/client setup. The purpose of this
Purpose: The first objective is to find whether M&A create value for pharmaceutical acquiring companies in the Western European market from a short-term perspective. Then we aim to examine the determinants of value creation for the pharmaceutical acquirer in the Western European market. Methodology: The event study is conducted to examine cumulative abnormal return for acquiring firms surroun
The entrepreneurial pitch plays an integral role in attracting financial capital for a new venture. Notably, previous research has shown that (1) female entrepreneurs are often subjected to discriminatory practices when applying for external capital and (2) entrepreneurs’ communication skills and personal attributes influence investor decision making. Building on these findings, this study explore
The principle of the persistent objector strikes at the heart of international law creating uncertainty over issues as how customary international law is created, whom it binds and how states actively can evade being bound by certain customary international laws. The mere existence of this principle gives rise to a great number of diverging interpretations. The study presented herein analyses the
This study examines the Refugees Welcome Movement campaign in Malmö between the period September 2015 and June 2016. The purpose of this study derives from the identification of a knowledge gap of descriptive, as well as analytical accounts that conceptualises the many and long withstanding occurrences of collective action within Social movement theory. This study aims therefore to tackle this kno
I dagens samhälle har det blivit allt vanligare att leva tillsammans utan att gifta sig och antalet sambor har ökat. Sambolagstiftningen bygger delvis på äktenskapslagstiftningen och de har således många likheter, men också många skillnader. Syftet med denna uppsatsen har varit att utreda huruvida makar och sambor bör jämställas ur ett rättsligt perspektiv genom att ha en gemensam lagstiftning istIn today’s society, it has become more and more usual to live together without getting married and the number of common law marriage has increased. The common law marriage legislation is partly based on the matrimony legislation and they therefore have a lot of similarities, but also a lot of differences. The purpose of this thesis has been to investigate if married couples and common law married
The importance to cut costs and to be as efficient as possible has never been as important as it is today in order to stay competitive in the market. IKEA are currently facing increasing challenges with the production growth due to a high demand from the market and goals for 2020. This large growth will affect the bottom line of the supply chain, the suppliers. The necessary production growth also
Every year, a big number of Swedish municipalities market themselves through an Emigration fair in Holland, with the aim to attract Dutch workforce, or more generally, bring new inhabitants to their respective region. In the marketing campaigns, specific stereotypic images of Sweden emerge, that are said to be specifically attractive to the putative Dutch migrants. The municipal representation in
A transit is a phenomenon where a planet passes between its host star and an observer blocking out part of the light from the star. This decrease can be measured and used to gain information about the planet. The Kepler and TESS telescopes are examples of space telescopes using the transit method to detect exoplanets. For systems with more than one planet around the same star variations between th
The Centre Party is one of the oldest political parties in Sweden that is still represented in the Swedish parliament. They are also currently the only party that originally developed from interest groups in the countryside. This paper focuses on the Centre Party’s church politics. The purpose of the paper is to find out how this agrarian party has shifted its’ policies regarding their church poli
Nitrogen dioxide (NO2) is an important air pollutant with both environmental and epidemiological effects. The main aim of this thesis is to explore spatial patterns and temporal trends of tropospheric NO2 concentrations globally using data from the OMI instrument aboard NASA’s Aura spacecraft. Additional aims are to validate the satellite data by comparing it to ground-based measurements, and to f
