Hydrocyclones are important pieces of equipment used within the mineral processing industry, where they are used for sorting ore particles suspended in water based on their size. The turbulent flow within a hydrocyclone is today usually modelled using demanding computational fluid dynamics (CFD) simulations. In this thesis, we explore the use of physics-informed neural networks (PINNs) as an alter
The use of technology, specifically machine learning, to address complex issues in developing regions has become increasingly prominent. In the context of wildlife conservation, combating poaching has emerged as a significant application of such technology. This research project aims to develop machine-learning-based low-cost antipoaching solutions. It presents three case studies, each exploring a
The date is October 8th, 2022 in Herzogenaurach, Germany. You are a board member of Adidas, a world renowned sportswear brand - a brand which has seen an immense growth over the past decade, growth which has also translated into a record valuation for the company in the stock market. But today is not a day which calls for celebration. One of your key collaborators, a person which you could attribu
Eating disorders are a common psychiatric issue, with women aged 19-24 at the highest risk of becoming ill. Research indicates that one of the primary causes of this illness is media usage, driven by the content of media platforms. Although it has been established through research that media content contributes to young women's critical perception of their body image, the publication of an est
Multi-agent pathfinding (MAPF) is becoming increasingly interesting because of its role in complex systems, such as warehouse sorting, search-and-rescue missions and autonomous vehicles. Another application for path planning is within production in industry when more advanced solutions than conveyor belts are developed. One such advanced transportation system is the XPlanar system, which is produc
Sialinsyra är ett samlingsnamn för enkla sockerarter som har en ryggrad bestående av 9 kol, med bland annat en karboxylsyra och en glycerolsvans. Sialinsyra förekommer naturligt i kroppen hos däggdjur. Hos människan är Neu5Ac den mest förekommande sialinsyran, och när man refererar ospecifikt till sialinsyra brukar det vara Neu5Ac som avses. Neu5Ac går att hitta i änden av de kolhydratkedjor som Sialic acids are a family of 9-carbon sugars which contain a carboxyl group and a glycerol chain. Neu5Ac is the most common sialic acid in humans and occurs at the terminal position of glycoconjugates covering the cell surface. Neu5Ac is involved in several different processes in the human body and plays an important role in several physiological conditions and pathogenic diseases. Sialic acid is
This case explores the rise and challenges of Vässla, a Swedish electric micromobility startup that positioned itself as a premium, sustainable alternative to gas-powered scooters. Despite strong brand differentiation, consumer demand, and initial success, Vässla faced operational difficulties and financial instability. Set in 2019, this case challenges students to assess whether Vässla’s brand st
This thesis explores the application of machine learning techniques to predict mortality risk using data from the Swedish Adoption/Twin Study of Aging (SATSA). Through the development and evaluation of multiple supervised learning models, including Random Forest and Histogram Gradient Boosting classifiers, the study examines mortality predictors across 10-year and 20-year timeframes. The models ac
Introduction: PARP14 belongs to the superfamily of PARPs that perform ADP-ribosylation of target proteins. The enzyme is involved in many cellular processes, including regulation of glycolysis, protein degradation, and genomic reparation. Background: PKM2 has been shown to be regulated indirectly by PARP14 to promote the Warburg effect. This describes an alternative glycolysis that cancer cells a
This study focuses on attitudes towards ADHD in social work amongst social workers diagnosed with ADHD, their managers, and their colleagues. The study consists of six semi-structured interviews, done mostly over video calls. Two of the participants are social workers diagnosed with ADHD and four of the participants are managers who have co-workers that have been diagnosed with ADHD. The result ha
This study aims to gain knowledge about social workers' experience of their work with undocumented clients and their perception of their room of action about their experiences with this client group. The study is of qualitative orientation and it’s been carried out through semi-structured interviews. The interviews were carried out with five social workers in different workplaces including non
De senaste 50 åren har antalet äldre i det svenska samhället mer än fördubblats. Trenden är densamma runtom i världen - människor lever generellt längre nu än förr. Samtidigt som vi får glädjas över att få spendera mer tid med våra älskade innebär denna högre ålder samtidigt en ökad risk för vissa sjukdomar. En av dessa åldersrelaterade sjukdomar är demens, vilket idag ca 140 000 personer i SverigIn 2022, approximately 32 million patients worldwide suffered from Alzheimer’s disease dementia. In addition to this, about 380 million people carried the biomarkers indicating Alzheimer’s, while displaying little to no symptoms. These people, however, always live with the risk of the disease progressing - making the development of a drug that can slow down or stop progression an endeavour of glob
