Validation of RFR Bermuda Swaption Priced with Hull-White model

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

Svavelutfällningar i västsvenska gasnätet: litteraturgranskning och dataanalys av biometan-, och naturgassammansättning

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

Distriktssköterskans möte med tonåringar drabbade av akne. En kvalitativ intervjustudie

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

Volcanic environment impact on andic properties and carbon dynamics in drained peatlands

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

The Brand Behind the Binge: Understanding Streaming Series as Brands

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

A Fully Integrated Transformer-Coupled Active Power and Impedance Detector for WLAN 802.11ax 5 and 6 GHz Frequency Bands

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

Påverkan på anläggningsbranschen till följd av onormala prisökningar på material och förnödenheter

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

Energy, economic, and environmental assessment of a solar-assisted heat pump system in Germany

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

Sulfur compounds in white and green liquor: Comparison of analytical methods for the determination of reduction degree

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

Diabetessjuksköterskors erfarenheter av att främja hälsosamma levnadsvanor hos patienter med diabetes typ 2 i den regionala primärvården – en kvalitativ intervjustudie

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

A 2x Time-Interleaved 24-GS/s 12-Bit Resistive DAC

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

S3P vs Arc Vapour deposition coating performance in machining 316L and Ti-6Al-4V

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

The balancing act of private forest certification schemes and public policy : A case study of Sweden's governance strategies in addressing forest degradation challenges

Concerns about the degradation of forests in Sweden have given rise to several sustainability initiatives, coming both from the private and the public sector. Forest certification established itself in a Swedish context in the 1990s and its uptake has coincided with developments in public policy. By applying Cashore et al. 's (2021) theoretical and conceptual framework, highlighting the intera

Brandtekniska beräkningar och simuleringar i brandutredningar

Fire investigations are used to analyze fire scenes, typically with the aim of finding the cause of the fire or to understand the fire spread. Fire investigations can be the basis for the outcome of legal cases, future accident preventative work or the outcome of financial disputes and can thus be important and impactful. It is therefore of the outmost importance that they are conducted so that

Evaluation of LLMs for Hardware Test Generation

Testing electrical units and systems is an important part of the production process. The development and generation of hardware tests are a labor-intensive process that requires expertise and deep understanding of the system’s behavior. This thesis explores the application of Large Language Models (LLMs) in generating hardware test steps. The research employs a comparative analysis of several LLM
