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

Detta arbete är en personlig analys med målet att stegvis få kunskap kring och slutligen definiera den musikaliska rösten hos artisten som filmkompositör. Med hjälp av en musikanalytisk metod, en undersökning och reflektioner är målet att kartlägga de huvudsakliga musikaliska och icke-musikaliska aspekterna som bygger den konstnärliga stilen.This work is a personal step by step analysis with the goal of defining the musical voice of the artist as a film composer. With the use of a music analytical method, research and reflections the aim is to map out the major musical and non-musical aspects that build the artistic style.

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

This project entails the development of a model for determining the spatial resolution in scanning applications of pulsed-neutron sources, such as at the European Spallation Source (ESS). The development of this model involves the simplification of the problem of representing a pulse neutron scanning across a sample by approximating the pulsed neutron beam as a continuous laser beam scanning acros

Increasing global temperatures have been shown to advance the breeding phenology of migratory birds, not least in temperate regions, causing birds to adapt the timing of other life-history events such as molt. At high latitudes, summers are shorter, and the birds must complete their post-breeding molt in the few weeks available before the conditions in the breeding site become unfavorable. I exami

Ögonen speglar om du flyttar eller stannar Migration är vanligt förekommande inom många olika djurgrupper. Att migrera kan ha många fördelar, som att undvika säsongsenliga utmaningar, men det finns också många nackdelar. Det tar på krafterna att förflytta sig och en migrant behöver dessutom olika anpassningar för att optimera resan. Här utgör synen ett viktigt sinnesorgan då många basbehov, som aAnimal migration is a widespread phenomenon that has evolved repeatedly in a diverse set of taxa. To cope with migration, individuals express a large variety of specialized behavioural adaptations, that rely on efficient sensory systems for extraction of relevant external information. Many behaviours are visually guided, such as foraging and predator avoidance, and most migratory animals possess e

Vägarna i Sverige är totalt cirka 57 000 mil långa. Av dessa anses cirka 43 000 mil vara tillhöriga enskilda väghållare, det vill säga någon annan än offentliga aktörer så som stat eller myndighet. Vägar har länge haft en stor betydelse ur ett flertal aspekter och det har alltid funnits ett stort intresse av att vidhålla ett gott infrastruktursystem. Bestämmelser om vägar fanns det redan i de äldThe aim of this paper is to improve the management of joint facilities and private roads. This was done by identify and investigat different problems connected to the private road organisations, formed through the regulation of joint facility and associations connected to them. One aspect of the investigation was if the area of included land connected to one joint facility had grown in size. By st

Bakgrund: Med anledning av Barnkonventionens inkorporering i svensk lag är det idag högst aktuellt att undersöka och diskutera hur barn upplever att de ges möjlighet att vara delaktiga i sin vård. Barns delaktighet bygger på en god kommunikation och relation till hälso- och sjukvårdspersonal. Trots föreskrifter om att barn bör vårdas på avdelningar avsedda och anpassade till dem, förekommer det re
