Current ripple can cause a lot of problems as it spreads in the DC-side of the TVS of electric and electric hybrid vehicles. Fully knowing the properties of the TVS can be used to build a simulation model to determine the spreading of current ripple beforehand, which in turn is useful for calculating component placement, optimal filter sizes, and component lifetime. Being the second in line of an

Idag är det många äldre flerbostadshus som står inför behov av renovering och energieffektivisering. Äldre byggnader har en betydligt högre energianvändning, för uppvärmning och varmvatten, än dagen nybyggda byggnader. Uppvärmningen av lokaler och bostäder svarade år 2014 för ungefär 35 procent av den totala energianvändningen. I kombination av en ökad urbanisering och ett renoveringsbehov av äldr

Cameras mounted on boats and in other similar environments can be hard to use if waves and wind cause unwanted motions of the camera which disturbs the desired image. However, this is a problem that can be fixed by applying mechanical image stabilization which is the goal of this thesis. The mechanical image stabilization is achieved by controlling two stepper motors in a pan-tilt-zoom (PTZ) camer

Background: Capsaicinoids are the compounds responsible for the pungent taste in the chili pepper genus capsicum. They are potent agonists of TRPV-receptors have large potential to be used as pharmaceutical agents for the treatment of various disease conditions associated to the peripheral and central nervous systems. Capsaicinoids are synthesized by the acylation of the aromatic compound vanillyl

Until now we still depend on oil and natural gas to supply us with fuels and other chemicals as a foundation to our economic advance. The global population is expected to reach 9 billion by 2050. With increasing population, the oil resource consumption will also increase, and an alternative source must be found and developed to supply us with chemicals and fuel needed for our economical advances,

Genetics for Manganese Manganese (Mn) is one of the essential minerals for humans and it is mainly present in blood, liver, intestine, and brain. However, at elevated concentrations, for example from occupational or environmental exposure, Mn may be toxic to the nervous system. Despite that Mn concentrations are tightly regulated in the body, concentrations seem to depend on our genetics. The ai

”How to win the war outside of the battlefield in ancient Greece and Rome – the generals explain” The purpose of this thesis is to shed some light on the topic of psychological warfare in two ancient, war-describing texts: The History of the Peloponnesian War, written by Thucydides, and The Commentaries on the Gallic War, written by Julius Caesar. The main reason behind this lays in modern approa

This study aims to give an overview of how nation branding is organised in the Netherlands by analysing the collaboration of individual institutions involved in nation branding and the so called ‘Holland Branding Collective’. Nation branding in the Netherlands is a fragmented field where institutions approach nation branding bottom-up with a combination of public and private actors. There are seve

The use of Electronic Flight Bags (EFBs) have become widespread and common among a majority of commercial airlines in Scandinavia and the United States in recent years. This development was enabled by modernized rules and regulations and the availability of suitable and affordable commercial-off-the-shelf (COTS) devices. This bachelor thesis studied EFB usage and user experience among pilots in com

Threat and Error Management (TEM) har framförts som en modell för att förstå, förklara och utbilda i hur olika flygsäkerhetsrisker uppkommer och kan hanteras för att uppnå en ökad flygsäkerhet. Den bygger till stor del på den tidigare utvecklade modellen för övervakning av operationell flygverksamhet, Line Operations Safety Audit (LOSA). Information har insamlats med hjälp av litteraturstudier, in

Denna uppsats syftar till att undersöka det så kallade parodiundantaget. Det upphovsrättsliga fenomenet innebär att ett bearbetat konstverk, i syfte att vara en parodi, faller utanför den ursprungliga upphovsrätten. Detta eftersom bearbetningen i egenskap av en komedibetonad prägel innehar ett i förhållande till sin förebild främmande innehåll och är därmed att anses som ett nytt och självständigtThis essay aims to investigate the so-called parody exception. The copyright phenomenon means that a processed artwork, in the purpose of being a parody falls outside the original copyright. Because of its form of parody, the processed artwork holds a foreign content in relation to the original and is thus considered a new and independent artwork, regardless of the copyright of the original. For s

The aim of this study is to do a qualitative research on the campaign Stop the Trucks. My methods include visual analysis of the campaign film and website, text analysis of the press release and interviews with three animal welfare organizations that were all part of the campaign. I will use a social constructionist perspective to depict how our moral view of non-human animals is socially construc

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

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
