To develop a meaningful allocation policy as the basis for economic welfare, it’s necessary to make some kind of comparison of the utility different people get with the various options that are available. If you put the greatest emphasis on raising the overall benefit of society, or seek to maximize other ideals such as liberty, equality and justice, the allocation will be different. I have in thi
By introducing spectral or polynomial functions to perturb the shape of the rotor in an electrical machine that was previously optimized by conventional means, it was shown that performance parameters can be further improved, in some cases significantly. This was accomplished by developing and applying an optimization method designed for use with a commercial finite element simulation software (Ma
A personal transporter is under development at LTH, Industrial Electrical Engineering and Automation, IEA. A wireless link is desired to develop control remotely for the transporter. The development of the control becomes easier without wires and if the transporter can move freely within the range of the link. A link is built, using Bluetooth devices and a microprocessor from Microchip. This link
In a modern society there is a constant increase in electrical use but at the same time the environmental awareness among consumers is rising. This master theses aims at investigating the possibilities in cost and energy efficient lighting control techniques. This master thesis is written for the Measurement Technology and Industrial Electrical Engineering division, IEA, within the Faculty of Engi
The increasing environmental awareness in today’s society has created a demand for vehicles with less environmental impact. One way to meet the resulting need is to construct hybrid vehicles, hybrid operation which involves a combination of different energy conversion- and storage principles. This project deals with just such a hybrid solution, a parallel hybrid. To construct a competitive solutio
The project was performed for FAS Converting Machinery AB (FAS) in Ystad with supervision from Industriell Elektroteknik och Automation at LTH. FAS is a company that makes machines for producing plastic bags on a roll. The problem given was to develop a sensor for detecting the perforations in the bags to ensure that the correct amount of bags was rolled up and that the tearing was in the right pl
The forceful storms and the stricter regulations from the government within the last years have forced E.ON to start a project called “Krafttag”. The goal of the project is to ensure uninterrupted power supply to the customers by investing in underground cables. A problem with the underground cables is the high natural capacitance that contributes to an enlarged current in the case of an earth fau
This project was done for the company Beijer Electronics Products AB and the task was given by the hardware development department of the company. The project was about developing a concept proposal for a new generation operator panels. This was done to inspire the product developers at Beijer Electronics with innovative ideas before the actual operator panel development. More in detail the object
I want to find out whether it is possible to draw any connection between payment behaviour and corporate reputation on a business-to-business level or whether it is rather trust that is effected and if so in both cases how and why. My qualitative research has an inductive approach and has been done by using an unstructured interview technique. I have used Chun’s definition of corporate reputation
Värdeskapande: musikbranschen i förändring är en kvalitativ studie av "den lilla" musikindustrin. Det empiriska materialet kommer primärt från åtta personliga intervjuer. Syftet är att försöka undersöka hur man kan skapa och finansiera värde i en bransch med sviktande intäktsflöden. Huvudteorierna i uppsatsen är Porters Five Forces samt Normann och Ramírez Värdestjärna. Författarnas slut
Syftet med denna uppsats är att undersöka hur beslutsprocesserna ser ut i nystartade konsultföretag. Syftet med uppsatsen är också att försöka identifiera en eller flera viktiga faktorer som styr beslutsprocesserna under företagsetableringen. I uppsatsen har vi använt oss av en abduktiv ansats samt av undersökningsdesignen fallstudier. Vi har varit helt inriktade på att genomföra kvalitativa inter
En sammanfattning av uppsatsen på maximalt 8000 tecken.
Syfte: Uppsatsen har som syfte att söka förståelse på anställdas reaktion på organisationsförändring utifrån ett kommunikationsperspektiv. Metod: Till sin karaktär är uppsatsen en fallstudie med en icke generaliserande deduktiv ansats som riktas gentemot Försäkringskassan. Teoretiskt ramverk: Uppsatsen teoretiska ramverk är uppbyggt på en socialkonstruktivistisk grund och riktar fokus gentemot kom
In recent years considerable investments have been made in the Swedish infrastructure and they are expected to continue in the near future. Large public investments within one particular area stimulate market growth and more companies will choose to establish themselves within this industry. When the market environment changes, even major players with large market shares will have to review their
Summary The station has always played an important role in development. In Sweden, railway building started in the middle of the 1900th century. The government financed the main rail lines, while private railway companies financed the small lines. The expansion of the railway lines was lead and planned by militaries, therefore the stations generally were drawn by trained militaries. Several statio
This paper describes the development of a DLNA digital media server. The server runs on top of an OSGi stack on a residential gateway. The server supports adding and removal of content sources at runtime. The problems with handling updates from diffrent media sources are analyzed and discussed. Also soulutions to these problems are also proposed. The diffrent techniques for the implementation are
Denna uppsats undersöker skillnaden i risk mellan en portfölj av bolag som är i råvarubranschen som producenter, och en portfölj av de råvaror de producerar och handlar med. Vi undersökte vilken portfölj som kan anses vara mest riskabel. Med hjälp av riskmåttet Value at risk (VaR) kom vi fram till spännande resultat, som visar på att det inte alltid är det förväntade som blir verklighet. Vi har ta
Med 30 miljoner dödsoffer är HIV/AIDS rankad som den fjärde vanligaste dödsorsaken i moden tid. En epidemi så omfattande påverkar hela samhällsstrukturer. Att HIV/AIDS påverkar den ekonomiska tillväxten har klargjorts men det råder delade meningar om hur den påverkar. Syftet med denna uppsats är därför att teoretiskt och empiriskt undersöka sambandet mellan HIV/AIDS och ekonomisk tillväxt, i ett f
