Extrema klimathändelser, såsom betydande översvämningar, utgör en risk för naturkatastrofer. På grund av klimatförändringarnas effekter förväntas södra Sverige få fler betydande regnväder som kan orsaka översvämningar i allt högre grad med mängden utsläpp. I denna studie undersöks dagens och framtidens översvämningsrisk i ett litet område i denna region, inom Kävlinges avrinningsområde. I det framExtreme climate events, such as significant flooding, pose a natural disaster risk. Due to climate change effects, the southern region of Sweden is anticipated to receive more significant rainstorms that could cause flooding increasingly with the quantity of emissions. This study examines the present-day and future climate’s flooding risk in a small area in this region, within the Kävlinge Watersh

Before electronic products reach the market, Functional Circuit Testing (FCT) is an essential process to ensure performance and reliability. Traditional FCT requires developing dedicated testing firmware for each batch of products, which increases both development costs and time. This thesis proposes a testing method based on Boundary Scan, provides an alternative that eliminates the need for firm

Purpose: The purpose of this paper is to analyze the effect woke marketing has on the consumer and the effect it has on the brand’s identity Methodology: The research paper uses a qualitative approach, including both primary and secondary data collection. The primary data was collected through six semi-structured interviews examining brand identity, woke culture and brand versus market orientation

Purpose: This paper aims to investigate how Monki’s decision to reduce its size range, a strategic choice that contradicts its inclusive brand identity, affects its brand image and how these actions can be justified. Design/method: This paper is based on two qualitative research methods. To gather primary data, semi-structured interviews were conducted to investigate the perceptions of young Swed

This thesis explores the economic, social, and institutional impacts of privatization policies in Latin America, focusing on both short- and long-term effects across different periods. Using a mixed-methods approach that integrates quantitative analysis with qualitative insights, the study assesses key indicators such as GDP growth, inflation, inequality, foreign direct investment (FDI), and polit

The transition from InterBank Offered Rates (IBORs) to Risk-Free Rates (RFRs) represents one of the most significant shifts in modern financial markets. This transition addresses concerns about the reliability and transparency of IBORs by adopting benchmarks based on actual market transactions. However, this change has far-reaching implications for the valuation of complex financial instruments, s

För att motverka den globala uppvärmningen sker i nuläget en övergång till förnybara energikällor, bland annat genom att injicera biometan i naturgasnätet. Integrationen av gas från olika källor har dock lett till ett problem: svavelutfällningar. Detta fenomen kan leda till att rör och utrustning går sönder och inte fungerar som de ska, samt en hälsorisk för operatörerna. År 2021 upptäcktes svavTo mitigate global warming, a shift towards renewable energy sources is in motion, including introducing biomethane into natural gas grids. However, the integration of gas from various sources has led to a problem known as elemental sulphur deposition. This phenomenon may lead to the breakdown and malfunction of pipes and equipment, posing health hazards to operators. In 2021 solid sulphur depos

This article aims to undertake a comprehensive cost-benefit analysis of SSAB's investment in green steel production under the HYBRIT initiative, focusing on the implications of operating within the EU Emission Trade System and an illustrative scenario employing a carbon tax. The study evaluates profitability and social benefits, utilizing time series models to forecast electricity prices in di

Bakgrund: Akne är en vanlig hudåkomma, som drabbar många tonåringar. Tonåren innebär en sårbar period i livet, med stora förändringar både psykiskt och fysiskt. Tidigare forskning visar att hudproblem kan få konsekvenser gällande självkänsla och psykiskt mående. Distriktssköterskan kan vara den första som möter tonåringar med akne och har därmed en viktig roll i att förmedla kunskap kring ämnet oc

The world’s soils are the most significant terrestrial C store. They store at least twice the amount of carbon as the atmosphere. Peatlands are the most significant long-term soil C store, even though they only cover about 3% of the terrestrial land surface and thus play a vital role in the global C cycle. Iceland is an island in the North Atlantic characterised by high volcanic activity, with vol

Purpose: The purpose of this study is to contribute to an expansion of what can be considered as a brand. Specifically, this paper examines how streaming series can be seen as brands through a brand identity lens. Methodology: A qualitative research approach, with a social constructivist perspective, has been done by applying the Brand Identity Prism, with the additional element brand promise, to

This thesis proposes a fully integrated transformer-coupled active power and antenna impedance detector for WLAN 802.11ax 5 and 6 GHz frequency bands. The detector is integrated into a transceiver, utilising the receive chain to down convert sensed RF voltage and current and digitally calculate the active power and antenna impedance on-chip. The RF current measurement is realized by a sense windin

Den svenska anläggningsbranschen har på senare år drabbats av betydande utmaningar till följd av onormala prisökningar på material och förnödenheter, vilket särskilt har haft en påverkan på fastprisentreprenader. Dessa kostnadsökningar har skapat en osäkerhet bland entreprenörer, särskilt på grund av bristen på tydliga riktlinjer och rättspraxis i kapitel 6 § 3 i standardavtalen AB 04 och ABT 06 s

Denna studie undersöker en parallell indirekt solassisterat värmepump (SAVP) för ett typiskt hushåll i Tyskland. Systemet utgörs av fotovoltaisk-termiska (FVT) solfångare och en värmepump (VP) för att täcka behovet av värme, varmvatten och hushållsel genom att använda solvärme, solel och nätel. Syftet var att utvärdera SAVP-systemets prestanda i Tysklands tre största städer för olika VPar med olikThis study investigates a parallel indirect Solar-Assisted Heat Pump (SAHP) system for a typical household in Germany. The system integrates Photovoltaic-Thermal (PVT) collectors and a heat pump (HP) to meet space heating, domestic hot water, and appliance electricity demands using solar thermal energy, solar electrical energy, and grid electricity. The objectives were to evaluate the thermodynami

Introduction: The forest industry might not be the first thing to come to mind when thinking of chemistry, but the analysis of cooking chemicals in wood pulping involves many laboratory methods. Background: The chemical recovery cycle is an integral part of the Kraft process, which makes laboratory analyses of different steps of the process necessary. In the recovery boiler, sulfur is reduced to

Bakgrund: Det är välkänt att ohälsosamma levnadsvanor, såsom osund kost, fysisk inaktivitet, alkoholriskbruk och rökning är välkända riskfaktorer som kraftigt ökar risken för komplikationer vid diabetes typ 2. Trots insikten om riskerna kan det vara utmanande att ändra levnadsvanor, vilket gör diabetessjuksköterskans hälsofrämjande arbete avgörande för att stödja och motivera patienter till positi

This study evaluates a 12-bit Time-Interleaved (TI) Digital-to-Analog Converter (DAC) operating at 24 GS/s, incorporating Return-to-Zero (RZ) scheming within its sub-DAC cores. Initially, the TI DAC demonstrates superior performance compared to a traditional single-channel DAC. However, the evaluation in this thesis reveals that the TI DAC is more sensitive to timing errors, such as clock skew and

Surface finish and surface integrity is important to produce high quality parts in the manufacturing industry. This is controlled by properties on the cutting tools such as edge radius, edge preparation, coating etc. Solid carbide tools are often coated with PVD coating technologies where AlCrN is a common coating composition. Tooling for small parts machining often creates issues with coating as
