A Sampling-Based Approach to Estimate Tree-Ring Width Chronologies

När de flesta ser eller hör talas om träds årsringar, är deras första tanke troligen att man uppskatta ett träds ålder genom att räknar ringarna. Om man skulle analysera ringarna mer noggrant och mäter deras tjocklek, kan de bidra till att reda ut mysterier kring tidigare klimat och växtförhållande. Det intressanta med trädringar är, att de växer tjockare under varma och gynnsamma förhållanden än In the field of dendrochronology, scientists work with the process of ordering different trees in time by using their annual tree ring width (TRW). The TRW data are logged in time series and cross-dated with each other to find out in which period of time they both were alive. The two TRW series are then conjoined by taking the average of their ring widths in each overlapping year, and this can be

Investigation on reinforcement learning for dynamic firewall configuration and its effect on edge devices

Cybersecurity has never been more relevant than it is today, as attacks become increasingly sophisticated. To keep devices safe from threats, a new type of smart firewall has become an active area of research. This type of firewall can dynami- cally configure itself based on incoming network traffic using reinforcement learn- ing. This research has shown promising results; however, its impact on r

Cosmological Evolution of Glueball Dark Matter in Dark Yang-Mills Sectors

Den materia vi känner till, atomerna som bygger upp planeter, stjärnor, gasmoln och galaxer, utgör bara en liten del av universums totala energiinnehåll. Resten består till största del av mörk materia och mörk energi. Mörk materia är materia som inte kan observeras med ljus, men vars gravitationella påverkan är nödvändig för att förklara hur galaxer roterar, hur galaxhoper hålls samman och hur strThis thesis investigates the possibility of dark matter arising from a confining dark SU(N) Yang-Mills sector with N=3,4,5. First, standard results from the established single-scalar-glueball framework are reviewed and numerically reproduced in order to follow the cosmological evolution through the confinement phase transition and extract the relic abundance. The results reproduce the expected qua

Inline Security Enforcement for Containers Using eBPF

This thesis explores the possibility of using extended Berkeley Packet Filter (eBPF) to implement inline security enforcement for containerized workloads. The objective is to automatically create profiles for runtime enforcement within cloud environments such as Kubernetes. A key feature of eBPF programs is that they can attach to various different kernel events, similar to the Linux Security Modu

Revisorsarbetet kopplat till korruptions- och mutbrott - Revisorns uppdrag och möjligheter att upptäcka korruptions- och mutbrott

Revisorn i Sverige idag innehar en viktig uppgift. Detta då han eller hon har som huvuduppgift att granska och kontrollera att ett bolags förvaltning och rapportering är korrekt. Utöver detta har revisorn enligt 9 kap. 42–44 §§ aktiebolagslagen en skyldighet att vidta åtgärder om denne, vid sin granskning av bolaget, skulle finna misstankar om att ett brott har begåtts. Syftet med denna uppsats haThe auditor in Sweden today has an important task. This is because his or her main responsibility is to review and ensure that a company´s management and reports are accurate. In addition to this, the auditor has an obligation to act due to Chapter 9, Sections 42-44 the Swedish Companies Act if, during the audit of the company, he or she discovers suspicions that a crime has been committed within

Från främlingar till söner av fosterlandet – En rättshistorisk undersökning av argumentationen bakom den judiska emancipationen i Sverige

Under 1700- och 1800-talet var judars rättigheter i Sverige starkt begrän-sade. Genom 1782 års judereglemente tilläts judar bosätta sig i Sverige under särskilda villkor samtidigt som de var föremål för omfattande re-striktioner. Under 1800-talet blev frågan om judars rättigheter och den ju-diska emancipationen ett omdebatterat ämne i Sveriges riksdag. År 1838 fick judar utökade rättigheter genom During the 18th and 19th centuries, the rights of Jews in Sweden were seve-rely restricted. Under the Jew Statute of 1782, Jews were permitted to settle in Sweden under certain conditions, while at the same time being subject to extensive restrictions. During the 19th century, the question of Jewish rights and Jewish emancipation was a heavily debated topic in the Swedish parliament. In 1838, Jews

Från skepticism till lovprisande – vad nu? - Synen på gemensam vårdnad över tid i svensk rätt

Fram till 1976 var föräldrars möjligheter till gemensam vårdnad begränsade. Vårdnadsformen var endast tillåten för gifta föräldrar som bodde tillsammans. Sedan dess har reglerna om gemensam vårdnad genomgått en omfattande reformering. I uppsatsen undersöks om synen på gemensam vårdnad har förändrats över tid i svensk rätt. Detta sker genom två delstudier. Den första delstudien är rättsdogmatisk ocUntil 1976, parents’ options for joint custody were limited. This type of child custody was only permitted for married parents living together. Since then, the rules on joint custody have undergone extensive reform. This thesis examines whether the view of joint custody has changed over time in Swedish law. This is done through two sub-studies. The first sub-study is legal-dogmatic and addresses h

Socioeconomic status is associated with process times in the emergency department for patients with chest pain

OBJECTIVE: Emergency department length of stay (EDLOS) is linked to crowding and patient outcomes whereas worse prognosis in low socioeconomic status remains poorly understood. We studied whether income was associated with ED process times among patients with chest pain.METHODS: This was a registry-based cohort study on 124,980 patients arriving at 14 Swedish EDs between 2015 and 2019 with chest p

A sample holder system for high-precision and reliable resistivity measurements of laboratory lime-cement samples

Lime-cement mixing is a method used for ground improvement of clay soils. Before mixing at a field site, laboratory samples are prepared and tested to decide the amount of lime-cement binder needed to reach the desired material strength. Strength measurements are not possible before a sample hardens, and the test process to predict final strength takes 30 days. Resistivity measurements are possibl

OMI – nytt begrepp för infarkt på grund av akut kranskärlsocklusion

The classification of acute myocardial infarction (AMI) based on ECG changes has evolved over time. Before the revascularization era, AMI was classified based on Q-waves that indicate loss of myocardium. After thrombolysis trials in the 1990s demonstrated a survival benefit, ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) classificatio

The role of atmospheric blocking on the calving of Greenland’s marine-terminating glaciers

The Greenland Ice Sheet (GrIS) is seeing an accelerated rate of ice melt, which increasingly contributes to global sea-level rise. Studies have reported a growing mass imbalance coinciding with a widespread retreat of the island’s glacial termini. The associated discharge of ice is driven by submarine melting and ice breaking off glacial fronts, a process known as calving. The rate at which calvin

Övergången från ACN-PCN till ACR-PCR på svenska flygplatser

Flygplatsbanor utsätts för stora belastningar från flygplan, vilket skapar ett behov av tillförlitliga metoder för att bedöma beläggningarnas bärighet. Traditionellt har ACN-PCN-systemet använts internationellt, men systemet har begränsningar eftersom det inte tar hänsyn till trafikvolym eller den kumulativa nedbrytningen av beläggningen över tid. För att åtgärda dessa brister introducerade ICAO AAirport pavements are subjected to severe loads from aircrafts, creating a need for reliable methods to evaluate pavement bearing capacity. Traditionally, the ACN-PCN-system has been used internationally, but the system has limitations since it does not consider traffic volume or cumulative pavement deterioration. To address these shortcomings ICAO introduced the ACR-PCR-system. The aim of this th
