Digitalisering inom högre utbildning är ett länge pågående projekt som fått sig en upptrappning under Covid-19-pandemin. Lärosäten världen över fick snabbt anpassa sig och ställa om till onlineundervisning för att skydda folkhälsan. Efter perioden av påtvingad onlineundervisning har högskolor och universitet mestadels återgått till campus-undervisning med en fortsatt strategi för digitalisering avDigitalization in higher education is a long-running project that has escalated during the Covid- 19 pandemic. Higher education institutions around the world had to adapt quickly and switch to online teaching to protect the public health. After this period of forced online teaching, universities have mostly returned to campus teaching with a continued strategy for digitization within higher educat

The norm critical perspective aims to make visible the norms that influence the planning of snow removal in Sweden. Norms are everywhere around us and can only be challenged if first they are made visible. As previous research has focused on the technical implications of snow removal this essay aims to bridge the gap between the technical and the social aspects of snow removal. By conducting a cas

This study focuses on the human factors associated with elevator use during evacuation in residential buildings. An online survey is conducted to explore seven factors that may influence people’s choice of elevators in China and the United Kingdom, including floor height, waiting time for elevators, crowd density in front of elevators, mobility limitations, instructions, fire location concerning p

Bakgrund: Anestesisjuksköterskan har en nyckelroll att genom sitt förhållningssätt, bemötande och kunskap om olika strategier, minska den preoperativa oron hos patienten inför anestesi. Denna studie har sin utgångspunkt i personcentrerad vård utifrån anestesisjuksköterskans perspektiv för att undersöka vilka strategier anestesisjuksköterskan använder sig av för att minska oron. Syftet: Var att be

When designing steel frames used in large hall buildings it is favourable to use a design tool set up with a programming language that can consider many different load cases and load combinations. These design tools can use the finite element method in order to perform the calculations needed to design the frames. Due to the extent of these design tools, the amount of elements used are restricted

Amelogenin, a critical protein in enamel formation, self-assembles into supramolecular structure that guide hydroxyapatite (HAP) crystal growth that is essential for the development of strong and healthy enamel. Phosphorylation of amelogenin at Ser-16 plays a pivotal role in modulating its self-assembly and functional properties, impacting the overall enamel biomineralization process. This post-tr

This master’s thesis is part of the project SolarFood, aimed at reducing post-harvest losses through improved solar drying techniques. The project focuses on developing locally adapted solar dryers, with short drying times while considering socio-economic factors for technology adoption and diffusion. This paper investigates adoption barriers and potential drivers for the diffusion of solar dryer

This paper focuses on constructing models that predict a Value at Risk (VaR) estimation for financial portfolios using hierarchical clustering and copulas. Traditional VaR models often assume linear dependencies and normal distributions, which can be poor assumptions for financial data - especially during extreme market events. This paper introduces a non-linear modeling approach using copulas to

Despite the widespread adoption and advanced capabilities of existing learning management systems (LMS), critical usability and functionality issues persist, hindering user experience and educational outcomes. Our research addresses these challenges by developing a comprehensive set of design principles designed to enhance LMS by following the design science research methodology. Through extensive

This thesis explores the Point-in-Time (PIT) in probability of default (PD) models, focusing on evaluating the degree of PIT-ness. Unlike previous studies that developed new measures for PIT characteristics, this research compares existing measures and frameworks to identify unique challenges and opportunities. By analyzing and testing existing measures for 1-year PD models, the study offers new i

The protein amyloid beta (Aβ) is a major component in the amyloid plaques associated with Alzheimer’s disease. This project concerns the most common version of this protein, Aβ40. In a supersaturated solution, Aβ40 monomers can aggregate to form amyloid fibrils. The solubility of an amyloid protein is equal to the concentration of the monomeric peptide in solution at equilibrium. To study the solu

This master's thesis explores the potential of integrating floating wind power into Power-to-X (P2X) megaprojects, with a focus on maximizing the output of chemical energy carriers through optimal energy mix strategies. The study evaluates the economic viability and technological efficiency of combining floating wind turbines with photovoltaic panels and battery energy storage systems (BESS) i

Syftet med denna uppsats är att utifrån ett referensobjekt undersöka hur broar med integrerade stöd grundlagda på stålrörspålar kan utformas för att uppfylla högt ställda deformationskrav för höghastighetståg. Användningen av integrerade stöd är stor i bland annat USA och England. De främsta fördelarna med integrerade stöd är att de innebär att broar kan utformas utan lager och fogar. Detta är fö

The awakening of the musical world from the Covid-19 pandemic has brought to life issues within our musical communities that are no longer deferrable, particularly from the composers’ perspective. The culturally niche status of contemporary western art music has remained largely unchallenged. However, the complications that arose during the Covid-19 lockdowns. concerning financial and physical lim

The increased density of base stations within cities provides improved radar coverage opportunities. The new generation of communication technology has given radar and other functions more room to maneuver. The work presented in this report aims to utilize existing communication base stations to implement radar functions to provide sensing services. In this way, the utilization of current dev

Small Modular Reactors (SMRs) present a transformative approach to nuclear energy, offering enhanced cost-effectiveness and ease of implementation compared to traditional large-scale reactors. This study investigates the dynamic behavior of the steam cycle within SMRs using Simscape MATLAB for simulation. The research focuses on understanding the thermodynamic principles and fluid dynamics that go

Den här uppsatsen ämnar att undersöka varför Sverige skickade in en Natoansökan efter Rysslands invasion av Ukraina under 2022 istället för efter annekteringen av Krimhalvön 2014. Sverige har en lång historia av militär alliansfrihet och den svenska säkerhetspolitiken har präglats av Hultqvist doktrinen sedan 2014. Varför övergavs den 2022? Genom en kritisk diskursanalys kombinerat med säkerhetise

Our problem considered was whether a virtual environment could be used for development of visual servoing control algorithms.

We have used a virtual environment for the comparison of several kinds of controllers. The virtual environment is done in Java, and it consists of two industrial robots, IRB 2000 and IRB 6, a camera stereo system with two cameras mounted on the end-effector of the IRB 6,

In process industry many control loops are far from optimally tuned. In this master's thesis a tool for rapid process identification and control design has been developed. The tool, which is implemented in Matlab 5.3, identifies a process model out of the step response of the real process. A PI or PID controller can then be designed and evaluated. The tool contains three different automatic de
