This report details a project I undertook with Lument AB, a company developing a new oral contrast agent that patients drink before CT-scans. The new formula has multiple benefits over current contrasts agents on the market for both patients and radiologists, however, it is harder for nurses to prepare. In the project, I research the feasibility of a medical device capable of preparing the contra
In this study a module for calculating the solar exposure of individual fluid cells was developed to more accurately represent the effect of photolysis on the pollutant dispersion in an urban street canyon. The module was tested and validated on 12 different cases, each with a different geographical location, time of year and/or time of day. It was used for four parallel simulations performed on a
Kvantifiering av motoriskt beteende hos råttor i fri rörelse Cirka 10 miljoner människor världen över lever med Parkinsons sjukdom och cirka 40 % av världens befolkning lever med långvarig smärta. Den här avhandlingen handlar om att implementera ett system för att hjälpa till att utvärdera behandlingar för dessa tillstånd, såsom djup hjärnstimulering (DBS). System som används för att förbättra DSystems evaluating potential treatment methods for Parkinson’s disease and chronic pain conditions, using rodent experimental models, are highly needed. Currently used systems are aiming to evaluate these kinds of treatment methods by analyzing the animal’s motor behavior. These systems either generate binary data or multifaceted data for when the rodent is spatially limited or data for when the r
Dystopian fiction first appeared as a literary genre in the 1870s and has since been known to conduct social criticism of the real world in a futuristic, fictive form. As it has evolved during the 20th century it has grown into a widely researched topic. In this essay I will analyze two young adult dystopian novels: Suzanne Collins’ The Hunger Games (2008) and Marie Lu’s Legend (2011). I have chos
It is a well-known fact that in any Application Specific Integrated Circuit (ASIC) design, verification consumes most time and resources. And when it comes to huge designs, finding bugs can be tedious given the area and the complexity. As per Moore’s law, the design complexity is increasing exponentially due to the growing demand for performance. Therefore, On-Chip communication becomes crucial. T
Eigenvalue analysis has been a key tool to science and engineering for several decades. Eigenvalues can predict the behaviour of many mathematical systems of equations but alone they cannot fully explain phenomena such as stability or stiffness. Together, eigenvalues and pseudospectra can give a better understanding of several phenomena such as instability in nonnormal matrices or operators. In th
Studien undersöker om och i sådana fall vilka könsstereotyper som används vid framställning av spelavatarer i League of Legends (LoL). I motsats till tidigare forskning avser uppsatsen att begripa varför detta inträffar. Forskningens resultat tog fram att föreställningar om kön appliceras på kvinnliga och manliga spelavatarer i LoL. Det framgick att spelavatarerna är överdrivna, sexualiserande ochThis thesis investigates if stereotypes and norms are projected in the virtual world. The study specifically aims to understand this through delving into the virtual game League of Legends to inquire if and, in that case, what gender stereotypes are used when constructing gaming avatars. Lastly, our thesis aims to answer and give an explanation for why this occurs. This dissertation is based on t
Online food delivery is becoming increasingly popular and has attracted more and more attention of scholars. However, the study on online food delivery faces a gap of consumer complaints. Those complaints can help service providers improve their service and business. This thesis aims to identify the factors that cause customers to complain and the behaviors customers show when they complain in the
Safety practitioners in high-risk organizations face many challenges in an ever changing safety environment. How do they keep up with these day-to-day challenges? This study explored the possibilities for a safety strategy to contribute to the Safety of the Royal Netherlands Air Force. Nineteen depth interviews and one a focus group comprising of thirteen participants were held. The participants w
Ohövligt beteende på arbetsplatsen är ett fenomen som uppmärksammats allt mer på de svenska arbetsplatserna. Syftet med undersökningen var att undersöka om det finns ett samband mellan upplevt ohövligt beteende på arbetsplatsen och hur detta är kopplat till individuella skillnader i personlighetsfaktorerna agreeableness och openness, samt till ålder och upplevd anställningstrygghet. Detta undersökWorkplace incivility is a phenomenon which has been observed increasingly in Swedish workplaces. The aim of the study was to examine whether there is a relation between experienced workplace incivility and how it is connected to individual differences in the personality factors agreeableness and openness, as well as to age and experienced job security. This was examined through a cross-sectional s
Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures

En studie i arkitektoniska kvaliteter i tid och rum Detta projekt är något av en lågmäld hyllning till en typ av arkitektur som utgör en bas i många av våra städers yttrekantsområden. Byggnader som inte från början var menade att göra något väsen av sig, men som i en senare kontext står ut och attraherar. Ambitionen är att undersöka vilka komponeneter som genrerar dessa platser; som på något sät
Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissio
The concept of this research is that by applying the proposed method, the trajectory of drift into failure can be made visible. The method itself consists of two sequential steps. For research purposes a third step is added. The first step is constructing a phased narrative, consisting of all the changes that have taken place within a particular organisational process subject to research. What has
This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13.7 keV, generated by the synchrotron radiation, impinges the material, and fluorescent X-ray spectra
Fracture risk in osteoporosis is increased and osteoporosis is the most common metabolic bone disease and treatment is expensive. Osteoporosis is diagnosed by measuring Bone Mineral Density (BMD), which does not consider other factors such as bone geometry or architecture. 3D-based models can predict risk fracture better than BMD, but they require 3D computed tomography. Solution of the problem is
Det är sen länge känt att de proteiner som utför cellernas funktioner mestadels inte är oberoende och enskilda, utan sitter ihop i proteinkomplex. Förståelsen om hur dessa komplex ser ut och sitter ihop är väsentlig för att till exempel kunna avgöra deras funktion eller förstå hur strukturändringar från sjukdomar och mutationer kan påverka dem. Bestämning av strukturerna på proteinkomplex brukar gDetermining how proteins interact with each other to form complexes is very important for understanding both disease and cellular functions, but experimentally determining the structures of these complexes is both tedious and slow, which is why a great number of protein-protein docking algorithms have been developed to predict them. To this day, conformational changes in protein backbones have bee
