In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f
Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. I den här studien vill vi strukturera och analysera observationer av huvudsakligen svavelpartiklar positionerade i stratosfären från naturliga och möjligtvis mänskliga källor, med hänvisning till va
Recently, several regions in southern Sweden suffered extremely low groundwater levels following a long-term infrequency in rainfall. In response, irrigation was banned in many of the affected municipalities during 2016–2017, amongst which Mörbylånga municipality was one. Because nearly half of the nation’s drinking water is extracted from groundwater, protecting and managing this vital resource i
For efficient treatment of many diseases of the lung, it is beneficial to deliver the medicine to the respiratory tract directly. This ensures a rapid response since it can enter the bloodstream directly through the alveolar epithelium. Consequently, also decreases systemic effects due to the local treatment. Dry powder inhaler (DPI) is today one of the most used inhalers for pulmonary delivery.
In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a
This paper examines the properties of the two recent structural break unit root tests developed in Harvey, Leybourne and Taylor (2013) and Narayan and Popp (2010). The properties are investigated by Monte Carlo simulations in an environment where two trend breaks of small to large magnitudes are present. We find that the Harvey, Leybourne and Taylor (2013) test has superior size and power properti
Perfluoroalkyl and polyfluoroalkyl substances (PFASs) are found globally in the environment, in humans and in wildlife and it is still not sure how these substances affect humans and animals. This study was performed as a systematic review to examine when these substances first attracted attention in different research areas. Also, to examine when the first publication was published and how the rese
Automatic segmentation of organs and tissues in computed tomography (CT) images can aid clinicians in anatomical contextualization for planning surgery or dosimetry. CT scans can cover varying axial ranges of the body. This thesis aims to develop a neural network based on vision transformers for segmenting organs and tissues in CT images of arbitrary axial ranges. Two models are presented, one bas
Title: AI regulation within auditing? - The Implementation of the AI Act and its Effects in the Audit profession Seminar date: May 29, 2024 Course: BUSN79, Master thesis in Accounting and Finance, 15 hp Authors: Emilia Werner and Alva Tvede-Jensen Advisor: Liesel Klemcke Key words: Isomorphism, AI Act, sensemaking, AI, audit profession Research question: “How is the audit profession adapting to th
This thesis examines the interplay between gender and the perception of impoliteness in the Japanese workplace. Firstly, impoliteness is an area in sociolinguistics that discusses face-threatening acts, perceived in situations modified by different aspects, e.g. context and the gender of the interlocutors. Secondly, gendered language is another area within sociolinguistics which gained popularity
This research examines how consideration of place attachment and community values can inform the development and implementation of fair and equitable climate change adaptation (CCA) practices in the Australian local government context. The research adopts a qualitative approach, using semi-structured interviews with expert interviewees and reflective thematic analysis to answer three research ques
In the context of China’s concerning decline in fertility rates and the widespread normalization of the ‘996’ overtime culture, the connection between overtime work and fertility assumes considerable importance. This research is firmly grounded in the theoretical framework of the Theory of Planned Behavior (Ajzen, 1991), which investigates the complex relationship between overtime work and fertili
This thesis conducts a legal investigation and critical analysis of the creation and establishment of a digital currency in the transactional agora of the European Union. The implementation of the digital euro as a new method of the European numismatic zone is a revolutionary neoteric strategy for efficiency in monetary transactions. A profound problem at the epicentre of this novel concept is the
Studying dissolution of oral drug substances is crucial throughout the drug development process. Current methods are time consuming and require large quantities of both the drug and dissolution media. Thus, exploring new methods is highly desirable. UV imaging, an analytical technique based on real-time absorbance measurements, can be used in early drug discovery to study drug dissolution and has
Transylvania’s countryside, characterized by a mostly agrarian society with a rich multicultural heritage is being threatened by Romania’s tendencies of chaotic modernization and rapid urbanization. This research aims to find a viable solution for sustaining the cultural, natural, and social environment in rural Transylvania, by analysing the potential of tourism development. Integrated Rural Tour
Motivation Efforts to address health disparities are often limited by the lack of robust computational tools for inferring genetic ancestry by calculating an individual's genetic similarity to continental groups. We have already shown that a preferred alternative to self-described race is using ancestry-informative markers (AIMs) that can be classified into ancestral components and used to estimat
Purpose: Developmental language disorder (DLD) has known consequences on academic performance, and adaptations to teaching methods and material are often required to counteract negative outcomes. This study used first-hand reports from students with DLD and their caregivers to explore how individual and school-related factors influence academic achievement and provision of educational support. Met
Spatially fractionated radiotherapy (SFRT) is emerging as a powerful tool in cancer therapy for patients who are ineligible for treatment with clinically established irradiation techniques. Microbeam radiotherapy (MRT) is characterized by spatial dose fractionation in the micrometre range. This presents challenges in both treatment planning and dosimetry. While a dosimetry system with a spatial re
