Framtagning av frekvenssyrd filterkärra

Rapporten handlar om framtagning av användarvänlig konstruktionslösning till en frekvensstyrd filterkärra och görs på uppdrag av Lars-Olof Larsson vid Filterteknik AB i Karlstad. Kursen är Examensarbete högskoleingenjörsexamen i maskinteknik, MSGC17 vid fakulteten för teknik- och naturvetenskap på Karlstads universitet under vårterminen 2014.I detta examensarbete tas en konstruktionslösning fram till en frekvensstyrd filterkärra som är en blivande produkt och ersättare till två tidigare filterkärror. Filterkärrans uppgift är att filtrera olika oljor från vatten och partiklar. En testkörningsprototyp fanns från början och huvudkomponenterna var utvalda. Genom produktutvecklingsprocessens metodik har ett antal prototyper tagits fram och utifrån det har den med bäst lösning valts och arbetats vidare med. Resultatet blev en kärra med samma ramstomme som tidigare liknade kärror.

Institutionella investerare - aktiva ägare eller passiva förvaltare? : En studie av hur institutionellt ägande påverkar ersättningar till ledande befattningshavare i Sverige

The purpose of this thesis is to examine whether institutional ownership has an influence on CEO compensation in companies where the institutions have invested. In order to fulfil the purpose of the thesis a quantitative study was carried out within the Swedish corporate context where we have studied Swedish institutional investors and companies quoted on the Stockholm Stock Exchange. Our period of study was the financial year of 2007.The empirical questions at issue is; Was there a connection between Swedish institutional ownership and the size of the CEO compensation, and, does Swedish institutional ownership lead to a certain type of CEO compensation in terms of structure?Our results did not suggest that an increased institutional ownership neither leads to a certain type of salary level nor a certain kind of salary structure. These results contradict earlier American research, which has been done within this area and has previously shown a secured connection.The reasons for our results may be many and it is difficult to state any concrete conclusions to why we received differing results.

COPD och Uppdragstaktik

Nato:s planeringsmodell Comprehensive Operations Planning Directive ska framgent användas för nationell militär planering. Anpassning till svenska förhållanden kommer att genomföras. Överbefälhavaren betonar redan i inledningen på ny Militärstrategisk doktrin att uppdragstaktik ska vara grunden för ledning i Försvarsmakten. Forskningen i uppsatsen fokuserar till mötet mellan planeringsmetod och betoning av att uppdragstaktik ska vara grunden för ledning.Syftet är att identifiera om operativ planering enligt COPD och doktrinens betoning av uppdragstaktik harmonierar. Genom det kan uppsatsen bidra med ny kunskap inom området och med ett analysverktyg för uppdragstaktik.För att genomföra analys av COPD har ett analysverktyg skapats, baserat på olika forskares teorier om vad som stödjer och motverkar uppdragstaktik.Forskningen visar att COPD i hög grad stödjer uppdragstaktik i ett filosofiskt perspektiv, men i lägre grad i praktiken.

Skapa värde med integrationer - En studie av hur affärsvärde och konkurrensfördelar skapas från integrationer i industribranschen.

Companies will increasingly begin to link their applications, and the technology that makesthis possible is called integration. The more applications that are connected, the more of the company's data flows through these integrations. It is also clear that data analyses to create business value and to get competitive advantages against its competitors are important. In this paper, we examine how companies create business value and competitive advantages throughthe integration platforms and metadata from the integrations. We have interviewedpeople from three companies in the industrial sector, each with an integration platform.We have also interviewed Enfo Zystems, a company that provides development andmanagement of integration platforms to these customers.

AUTOMATISK PAN/TILT-KONTROLLER FÖR ANTENNINRIKTNING

This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.

Dynamisk tredimensionell visualisering av fot med datortomografi

Projektets syfte var att med modern datortomografi (computed tomography, CT) skapa tidsupplösta tredimensionella sekvenser, även kallade 4D-sekvenser, med låg stråldos och tillräckligt bra upplösning samt att påbörja en implementering av denna metod på Karolinska Universitetssjukhuset i Huddinge. För att få ett så bra resultat som möjligt involverades ett antal personer med olika medicinsk yrkesbakgrund och olika kompetensområden.En fantomstudie utfördes genom att dra ett fantom med en konstant hastighet genom CT:n med hjälp av en motor. Efter detta utfördes en pilotstudie på två försökspersoners högerfötter som utförde en rörelse under olika lång tid under en CT-undersökning.Scanningen av fötterna genomfördes först efter att det visade sig att scanningen av fantomet gav adekvat resultat med avseende på bildkvalitet och stråldos. För att avgöra detta gjordes en analys av bilderna på fantomet och en dosberäkning.Scanningen av fötterna genererade tolkningsbara bilder med tillräckligt låg stråldos. Denna metod kommer därför säkerligen användas i undervisnings- och forskningssyfte.

Rapportera Mera?: En kvalitativ studie av hur svenska finanschefer uppfattar kravet på kvartalsrapportering

The purpose of this paper is to study how Swedish CFOs perceive that the requirement for companies to issue quarterly reports affect business operations in the company. The fact that it is regulations on the Stockholm Stock Exchange, and not the law, that requires companies to issue quarterly reports makes Sweden unique in Europe. The paper is based on interviews with CFOs from 32 companies quoted on the Stockholm Stock Exchange. The major finding in the study is that a majority of the CFOs perceive that the pressure for short term results, created by quarterly reports, affect their work and the investment decisions made in the company. Also CFOs feel that the market over interprets the information given in quarterly reports.

Solenergisystem i Hammarby Sjöstad

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

Elektronisk motorstyrning för ottomotorer

The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.
