This research investigates the subject of Data Democratization (DD), the effect it has on fact-based decision-making, and how users perceive this within the organization. DD is a fairly new initiative, empowering more employees with increased access to data to improve their use of it and to a greater extent be able to make decisions based on data. The idea for this paper originated from the lack o
The aim of this empirical study was to find out which characteristics, behaviors, and drives high-performing women have in common in order to illuminate why they have become successful in their work. The aim also included getting insights into some of the challenges that these women meet. Participants were fifteen high-performing women who work in business and academia in Sweden. Semi-structured,
The nuclear reaction 10B(n,alpha)7Li* was utilised to develop a neutron detection system. This system has the purpose of being used to detect the thermal neutron radiation emitted by spent nuclear fuel, before it is transported to a final repository. This to investigate the content of the fuel-containing capsules, primarily to ensure non-proliferation of radioactive materials in the nuclear waste
Cancer is a widespread and commonly fatal disease in constant need of new treatments. Traditionally, new pharmaceuticals have been tested in 2D models. This is not ideal, as 2D environments do not reflect the in vivo milieu of the cells. Instead, it has been increasingly suggested to implement 3D models, which are thought to be more predictive of in vivo responses to treatment. It has been shown t
Background: environmental impact from health care contribute to a substantial part of the public sector’s consumption based emission of greenhouse gases in Sweden. An issue, recognized by the health care sector itself, is the increasing use of single-use products. Objective: to compare environmental impact and cost differences between a single-use, ResposableTM, and mixed setup of the surgical in
Aim: Renography with 99mTc-MAG3 is one of the most common nuclear medicine examinations. It’s extensive use justifies a thorough investigation of the methods used to accurately determine the split renal function, for instance with regard to background subtraction and correction for renal depth differ- ences. Previous studies on this subject have been made, mainly on patient image data, thus the ”t
This thesis focuses on predicting the usage efficiency of e-scooters through the application of a Spatio-Temporal Graph Neural Network (STGNN). The predictions made by the STGNN will be compared with classical machine learning (ML) methods, including Random Forest (RF), Artificial Neural Network (ANN), and Linear Regression (LR). To facilitate the prediction of usage efficiency, the Time to Bookin
As technology progresses, it seems to become increasingly inevitable for everyday objects in our homes to incorporate advanced features, to increase functionality, convenience, and energy management. This master’s thesis presents the continuation of a Bluetooth lighting system, aiming to develop a comprehensive website solution for handling the provisioning and configuration of Bluetooth Mesh devi
Background/purpose Quantitative susceptibility mapping (QSM) is an MRI-based post processing technique to evaluate the magnetic susceptibility, χ, of human tissue using phase data. While brain imaging has been the most common application, other areas have also raised interest. For example, QSM of the articular cartilage of the knee has been suggested as a means to study the degeneration of this ti
Terahertz radiation is a useful tool for inducing lower-energy excitations in matter, where it can be used to cause structural changes through direct interaction with the crystal lattice. Sub-picosecond optical pulses can be used to generate intense broadband terahertz pulses through optical rectification in nonlinear crystals, reaching peak electric fields of several MV/m and conversion efficienc
This master’s thesis aims to support product-centered companies in their transition to a circular economy (CE) by developing a digital self-assessment and decision support tool. Circularity is a complex field that demands collaboration across multiple system levels. Although a wide range of frameworks, regulations and guidelines exist, the transition remains difficult for companies to navigate. Ex
Lignin is a by-product from the paper industry and has shown good liquid barrier properties according to previous studies. The objective of this work was therefore to study the liquid barrier properties of hydrotropic extracted lignin through steam explosion (STEX), obtained from spruce. The lignin was dissolved in three different solvents (concentrations: acetone 65 %v/v, ethanol (EtOH) 80%v/v an
This thesis studies the flood risks in Yogyakarta City, Indonesia, focusing on the Kali Belik River area, and explores the regulations and design principles aimed at enhancing flood risk reduction and management in the city. The discussion begins at the global level, analysing frameworks such as the Sendai Framework for Disaster Risk Reduction, and transitions to the local level, assessing the cha
Galectins are proteins that bind to carbohydrate structures, with high affinity for β-galactoside ligands that exists naturally in our bodies. They are involved in the development of various diseases, including central nervous system diseases and cancer proliferation. Galectin-1, which is the focus in this thesis, is related to anti-inflammatory and neuroprotective functions in the brain. Drug del
One measure required to reduce greenhouse gas emissions is changed consumption behaviours in affluent contexts. This might be motivated by sufficiency, and while the concept is often related to reduced material consumption, its practical implications regarding food consumption have not been explored to the same extent. To investigate how the literature on sufficient consumption may offer new insig
In Axel Honneth's "The Struggle for Recognition" (1995), love as mutual recognition is dealt with through the psychoanalytic theory of Donald Winnicott, who focused principally on relations between parents and their young children. Consequently, Honneth's conceptualisation of love is ill-suited for application in the study of late modern adult romantic relationships. In this thes
HPLC is one of the most widely used analytical techniques in the pharmaceutical industry used for separation and identification of compounds in complex formulations. Despite its advantages, HPLC method development remains challenging. This is due to the need to optimize multiple interdependent parameters simultaneously, while gaining high precision, reproducibility, and efficiency. Even minor cha
This thesis analyzes Socialstyrelsens (Swedish Social Services) guidelines for endometriosis healthcare, with the aim of understanding the social aspects of the medicalized field of endometriosis. Former research on transnational and Swedish endometriosis experience, studies on endometriosis guidelines and Socialstyrelsens’ guidelines for healthcare, is presented to contextualize the project. The
CERN operates complex underground facilities, with the Large Hadron Collider (LHC) posing unique fire detection challenges due to ionising radiation, long tunnel spans, and variable ventilation. To address the limitations of aspirating smoke detectors in both current and future CERN facilities, Distributed Temperature Sensing (DTS) systems using radiation-resistant optical fibers are being exp
As industrial sectors and digital infrastructure expand, the global demand for high-volume, reliable manufacturing of thermal management solutions like heat exchangers continues to accelerate. This thesis investigates the design and optimization of an automated robotic assembly cell for heat exchanger production at Alfa Laval using Discrete Event Simulation (DES). The primary objective was to defi
