Avhandlingen syftar till att undersöka om det är mjöligt att finna billiga approximationer till extremvärdena för kvadratiska former. Dessa extremvärden kan t.ex. användas för feluppskattningar i tidsstegningsmetoder för lösning av differentialekvationer, men då extremvärdena måste uppdateras varje steg måste metoden vara billig. Här undersöks dessutom "stora" matriser och möjligheten atIn this thesis approximations to quadratic forms using Krylov subspaces are presented. These quantities are approximations of the norm and logarithmic norm of a matrix. In order to find these quantities an eigenvalue problem has to be solved, but because of limited storage and time, this is not feasible in practice with large matrices. Instead one can project this problem down to a problem of smal

Att spåra kunder i online-butiker har länge varit en självklarhet för branschen. Det de flesta inte vet är att det även är möjligt att spåra kunder i fysiska butiker, utan att den personliga integriteten går förlorad.Retail intelligence is a big and upcoming thing in the brick and mortar-world of retail. This simply means that the resellers want to gather as much data about their products,and possibly also their customers, as possible. Some stores might want to know different information than others, but the fact of the matter is that gathering off-line data is slowly entering the world of business. There are

China has recently completed an important part of the reform process of its banking system partially privatising its major Commercial banks with both domestic and foreign capital. This paper investigates the effect of different ownership structures to banks’ economic performance, using a panel data analysis of 57 banks over the 2000-2016 period. A specific focus will be given to the Big-Five Comme

This thesis conducts a comparative analysis between Sweden and China on the topic of consumer adoption of cross-border e-commerce. Based on the data collected by a questionnaire survey, it offers description about demographic characteristics and behaviour of consumers in cross-border e-commerce from both countries. Moreover, then, the linear regression firstly shows the relation among adoption, co

Uppsatsen är en beskrivning och analys av pariskorrespondenten Claes Lundins arbete och artiklar från Paris till svensk press men också av den bild av det franska samhället under 1860-talet, som Lundin förmedlar till tidningarnas läsare. Utrikeskorrespondentens position i mediesystemet analyseras både utifrån begrepp i Ulf Hannerz forskning kring utrikeskorrespondenters arbetssätt och arbetsvillko

The Gorkha earthquake that happened on the 25th of April and its aftershocks on the 26th 2015 was a remarkable event in Nepal’s history. Okharpauwa, a village development committee in Nuwakot District, was considerably affected by the aftershocks and the affected people were in the process of recovering when this master’s thesis was written. A dominant idea within disaster recovery literature is

This thesis examines a local low-carbon energy transition in an urban context with regard to energy justice. It takes the Vauban district in Freiburg (Germany) as a case study which has been described as a successful case of energy transition and a model for sustainable urban development. From a theoretical point of view, energy justice encompasses a fair distribution of costs and benefits of an e

Arkitektur som har spår av förändring och på olika sätt förmedlar tidens förlopp har ett mångfacetterat djup. De förändringar som sker i byggnader går att avläsa som en ansamling fysiska och mentala lager, vilka genereras i en kontinuerlig och ständigt föränderlig process. Lagren är ett resultat av mänsklig aktivitet och tillsammans förmedlar de vilka vi än gång varit men återspeglar också hur vi

För att upprätthålla vår höga levnadsstandard och ha möjlighet att fortsätta utveckla vårt samhälle måste vi lära oss att hantera våra resurser på ett hållbart sätt. På kommunnivå kan man arbeta med detta genom att arbeta avfallsförbyggande. Ett allt vanligare sätt för kommuner att arbeta med dessa frågor är genom att arrangera kampanjer som fokuserar på avfallsförebyggande hos privata hushåll. Ma

An increasing amount of research findings is showing that higher engagement in cognitive tasks alleviates the interference of anxiety and worry on task performance as compared to lower task engagement. Yet, it is still not clear which cognitive functions are mostly contributing to this relieving effect. To add to the current knowledge, the present experimental work investigated the relations bet

In recent years Swedish social services have experienced increased workload and employee turnover. Eight out of ten social workers experience a high workload. The reported work related diseases within the field increased by 123 % between 2014 and 2015 and one out of four social workers experiences psychological strains. Young and new employees within childcare services are often more represented i

Resource related challenges are becoming increasingly severe. The shift towards a circular economy is viewed as one prominent way to overcome the challenges. A shift towards a circular economy would partly require new business models, commonly referred to as circular business models. In order to enhance the development of circular business models, there is a need to understand how companies with c

Intresset för upphandling med partnering ökar stadigt i Sverige då samarbetsformen medför goda effekter såsom till exempel minskade konflikter, ökad kvalité, tidsoptimering, minskade kostnader samt närmare relationer. Idag tenderar partnering i största utsträckning ske mellan entreprenör och beställare men även andra aktörer, såsom till exempel underentreprenörer, inkluderas allt oftare i samarbet

Purpose: The purpose of this thesis is to make a comparison and measure what effect the integration of real-time in transmedia storytelling has on social media engagement. Furthermore, this research aims to add new insights to the social media engagement and real- time marketing field, by incorporating knowledge from the transmedia storytelling literature. Problem: Previous research argues that tr

-The purpose of this work is to investigate and identify the most efficacious methods to optimize train maintenance and operations during winter months. The study analyzes scheduled and unscheduled maintenance problems during winter months and considers various options on how to streamline current methods and procedures by identifying key areas and addressing optimization. This study presents prop

The aim of this study was to investigate how older people are described as victims in the morning and evening press in Sweden. The aim was further to make a brief comparison of how it looked at 25-year intervals during the periods 1991-1992 and 2016-2017 to see if and how the victim discourse has changed. The three issues I assumed were: how older people exposed to crime are presented in Swedish p

Epilepsy is one of the most common neurological diseases that affects 1 % of the human population. After an initial insult, the brain undergoes several changes that lead to hyperexcitability. These changes include downregulation of both GABAA receptor subunits and CB1 receptors. These receptors normally work to decrease excitability, so their downregulation leads to an increase in excitability. If

Since the early 1990’s, sector-wide evaluation reports have identified substantial weaknesses connected to women’s empowerment and gender equality interventions. These weaknesses result from the failure to institutionalise activities, a lack of resources and deficient reporting of results. Additionally, recent evaluation reports have identified the same weaknesses as were identified in the early 1
