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

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

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

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

In the 20th century, big innovative steps were made in the cutting tool industry. Two Swedish companies, today Seco Tools AB and Sandvik Coromant, were some of the first companies to use cemented carbide as tool material. In 1969 Sandvik Coromant introduced a layer of titanium carbides on top of a cemented carbide substrate to improve its performance. Coating materials have been continuously devel

Architecture and space in the scale of a family house can be about rounded shapes interplaying with straight lines and light. In today’s newly built houses in Sweden I sense a lack of variety in combinations of these elements. This project therefore aims to experiment with rounded shapes and straight lines together with light. A collection of the explorations act as the base to draw a house. A vil

Portfolio optimization involves selecting assets to maximize risk-adjusted returns, typically using linear methods like Mean-Variance Optimization (MVO). However, such approaches may not fully capture the complexities of financial markets. This study leverages recent advances in machine learning, specifically reinforcement learning with deep neural networks, to identify alternative methods that ma

As the life expectancy continues to increase in Sweden, with an estimated increase of 5 years for women and 6 years for men between 2024 and 2070, there is an increasing need for solutions that enables elderly people, and individuals with a need for extra safety, to live an independent and healthy life. One solution that is under development, is a mobile social alarm in the form of a watch, which

With the rapid growth of software dependencies in critical systems, detecting vulnerabilities early in the development cycle has become a necessity. While extensive research exists on vulnerability detection in low-level languages like C/C++, there is a significant gap in addressing vulnerabilities in higher-level languages, including JavaScript, Python, and PHP. This thesis explores the feasibili

This thesis examines the norms, boundaries, and perceptions surrounding homosexuality in Swedish gay press between 1969 and 1973. The aim is to analyse how normative systems influenced the formation of identity, self-image, and sense of community among homosexual individuals. The aim is also to analyse how heteronormativity and the transgression of norms affected their relationship with society an

Bakgrund: Världshälsoorganisationen (WHO) rekommenderar att barnet helammas under de första sex månaderna. Trots amningens hälsofördelar för både moder och barn har det visat sig att rekommendationerna är svåra att uppnå globalt. Modern upplever psykologiska, fysiologiska och sociala svårigheter med amning. Syfte: Syftet var att belysa mödrars upplevelser av främjande respektive hämmande faktorerBackground: The World Health Organization (WHO) recommends exclusive breastfeeding for the first six months. Despite the health benefits of breastfeeding for both mother and child, it has been shown that these recommendations are difficult to achieve globally. Mothers face psychological, physiological, and social difficulties with breastfeeding. Aim: The aim of this study was to highlight mothers&

I Sverige lever många barn i hem präglade av våld och övergrepp, trots att de har en ovillkorlig rätt till skydd. Umgänge med en våldsutövande förälder, även kallat tvångsumgänge, kan få allvarliga konsekvenser för barnet. När domstolen beslutar om umgänge ska barnets bästa vara avgörande. Vid bedömningen av barnets bästa ska risken för att barnet far illa särskilt beaktas. Syftet med uppsatsen äIn Sweden, many children live in homes marked by violence and abuse, despite having an unconditional right to protection. Contact with a violent parent, often referred to as forced contact, can have severe consequences for the child. When courts decide on contact arrangements, the best interests of the child must be the determining factor. In assessing the child’s best interests, particular consid

Bakgrund: Barnmisshandel är ett globalt problem, som påverkar barn i alla samhällsklasser och miljöer. Vårdpersonal är en viktig och central del i identifieringen av barnmisshandel. Trots det uteblir anmälningar av barnmisshandel i viss mån, även i de länder där det råder anmälningsplikt. Syfte: Syftet var att undersöka vårdpersonalens upplevelser av att identifiera och anmäla barnmisshandel med

Det primära syftet med studien var att undersöka genomförbarheten av dagliga skattningar två gånger dagligen av symtom, psykologisk flexibilitet (PF) och funktion hos vuxna med systemisk lupus erythematosus (SLE). Det sekundära syftet var att undersöka sambandet mellan de vanligaste och mest besvärande symtomen på SLE (dvs. smärta, trötthet, ångest, depression och kognitiv påverkan), hälsorelateraThe primary aim of this study was to assess the feasibility of obtaining twice-daily recordings of symptoms, psychological flexibility (PF) and functioning from adults with Systemic Lupus Erythematosus (SLE). The secondary aim was to investigate the relationship between the most common and burdensome symptoms of SLE (i.e., pain, fatigue, anxiety, depression and cognitive impairment – CI), health r
