Detta är den populärvetenskapliga sammanfattningen av masteruppsatsen ”Designing and Maximizing Switch-Mode Efficiency of MODPSU, the Modular Power Supply”. Den sammanfattar teoretiska studier och resultat från mätningsexperiment som genomförts i syfte att minimera totala förluster för DC/DC-switchade nätaggregat.This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. However, one of the major

The purpose of this thesis is to question and discuss whether the complication of power-relations created upon the present surface of the human body can be surpassed, by re-conceiving the body and ultimately leaving the body behind, without the loss of Being, through the critique of art and photography. This overall query has been broken down into three questions. (1)‘Does the solution behind the

This work investigates visualizations of two crises; terrorism and climate change. Focus lies on mediated images concerning Paris 2015, where terrorist attacks had an impact on the following UN climate change conference (COP21). The symbol of the Eiffel Tower was used to portrait both issues and will be studied through a semiotic analysis. Terrorism and climate change are argued to be interlinked,

Surveillance cameras are vital in the nuclear power industry where the reactor equipment must constantly be kept under surveillance to maintain safety. Constant monitoring is however difficult due to the highly radioactive environment, which cause cameras to malfunction and eventually break. Malfunction typically manifests itself as quality degradation of the image from the cameras. Initially, tem

The present paper aims to analyze the impact of eleven macroeconomic factors and the one-month lagged stock return on the performance of ten sectors within the United States. The set of potential factors is based on previous research as well as published methodologies of credit rating agencies. It includes the one-month lagged stock return, earnings per capita, consumer price index, private consum

Bakgrund: Vårdskador är ett globalt problem inom hälso- och sjukvården. Rapportering av avvikande vårdskador är av stor betydelse för patientsäkerhetsarbetet att förbättra kvalitet och säkerhet i vården. Syfte: Syftet var att undersöka antalet avvikelser som rapporterats, samt fördelningen mellan avvikelser rapporterade från operations- och anestesisjuksköterskor vid ett regionsjukhus under de sen

This study examines the generalization process of trademarks from a consumer perspective. The phenomenon verbification, when trademarks are used as verbs, is particularly in focus. Since it is the consumers that determine whether trademarks are generic, this study examines consumers’ role more closely. Through a qualitative study of the trademark Vipps, qualitative interviews has been conducted to

Global environmental issues concern a growing number of people and businesses are expected to communicate efforts towards environmental sustainability. Due to the controversial nature of its business practices and contribution to environmental problems, the oil industry holds a poor reputation and is considered to have a special need to communicate their efforts towards more sustainable business p

Although successful intranet requires active employees that engage in dia-logues to exchange knowledge, the employee is neglected in the research within the field of internal communication on intranet. This study problema-tizes organizations’ high expectations on intranet and highlights the em-ployee perspective. The purpose of this study is to gain a deeper knowledge and understanding of sensemak

Miljöproblemen i Hanöbukten, hur går vi vidare? Att kunna bada och fiska i havet är något som de flesta av oss tar för givet, men är något vi inte kan göra längre. Dessa intressen är hotade på grund av de kombinerade effekterna av klimatförändringar och mänskliga aktiviteter, såsom övergödning, överfiske samt föroreningar, vilka har betydande negativa effekter på flera kustområden runtom i världHuman activities such as eutrophication, overfishing and pollution have significant effects on marine ecosystems. The marine environment of the Baltic Sea is historically one of the seas in the world that has been contaminated for the longest time. This study focuses on Hanö bay, which is a part of the Baltic Sea where the problems are presumed to be of major character. Poor water quality, poor fi

I takt med att EU skapat sig en större roll för samhandeln mellan de anslutande medlemsländerna har den EU-rättsliga ordningen inverkat på vissa av de nationella rättsystemen. Ett relativt nytt system har frivilligt införts i den svenska rätten vilket behandlar bekämpningsmedel för konkurrensöverskridande samarbeten som karteller. Denna kartellbekämpande ordning, kallad eftergiftssystemet, har intAs the EU has become an important role for the reciprocal trade between the acceding Member States, the legal order of EU has had an effect on some of the national legal systems. A relatively new system has been voluntarily introduced into the Swedish law, with the purpose to combat competitive cross-collaborations like cartels. This cartel enforcement order, known as the Leniency system, has not

Syftet med studien är att undersöka hur sociala entreprenörer i Sverige konstruerar sin organisationsidentitet samt hur de positionerar sig gentemot närliggande aktörer.

The empirical material consisted of seven children’s books published between the years of 2008 and 2015. The method used for this study was Fairclough’s Critical discourse analysis. The empirical findings were analyzed from Hirdmans (1988) theory on gender system to make visible the norms
