This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

This essay is an examination of the examples in Kant?s Critique of Judgement. The examples which I have focused on all converge in an idea of wildness. These examples of the beautiful are illuminated by a culture-historical perspective, where the literary and scientific travelogue genre is of great importance. Apart from being exegetic and culture historical, my method is also analytic.

The company Västra Mälardalens Kommunalförbund, VMKF, wishes to revise and optimize their present data and IP-telephony network as of today consists of the three municipalities Köping, Arboga and Kungsör. As a municipal corporation, they seek consultation regarding internal as well as external review and investigation of the main structure of the network, its functionality and safety. By today?s increasing demands of Internet accessibility, availability of services and security far more extends the requirement of a complete network design. The foundation of networking rests on the balance between each of these necessities.

This thesis investigates the effect of profit growth and profitability on market capitalization amongst Nordic companies during the turbulent period 1997-2005. Our results suggest that profitability have a significant impact on market capitalization for six of the nine years studied, whereas profit growth does not seem to affect market capitalization. Consequently, our results imply that the effect of other factors on share price performance may be greater than previously suggested. These findings are only partly in line with theories on corporate valuation which suggest that market capitalizations are to a great extent driven by both profit growth and capital returns, regardless of whether the stock market is particularly unstable..

Itera Networks is no exception when it comes to rapidly developing new and better network solutions for themselves and for their customers. With these requirements in mind their needs for an analysis of the existing communication solution becomes very obvious. This project contains such an analysis in which various studies of the existing network environment have been made.

Syfte med min studie var att undersöka hur idrottslärare tänker kring individanpassad undervisning som erbjuder valmöjligheter. Mina frågeställningar var:Ska man anpassa undervisningen så att eleverna erbjuds olika valmöjligheter och i så fall varför?Vilka för- och nackdelar finns det med en anpassad undervisning som erbjuder valmöjligheter inom ämnet idrott och hälsa?Hur kan man genomföra anpassad undervisning som erbjuder valmöjligheter inom ämnet idrott och hälsa på ett bra sätt? Som metod valde jag att ha en kvalitativ ansats för att på så sett få en djupare förståelse för hur idrottslärarna tänker och resonerar kring att erbjuda valmöjligheter. Jag genomförde fyra intervjuer med olika idrottslärare som alla hade ett minimum av 10 års praktisk yrkeserfarenhet. Samtliga idrottslärare ansåg att det är viktigt att erbjuda eleverna valmöjligheter samt att det finns många för- och nackdelar som man måste vara medveten om.

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

This study examines the effects of credit risk and information disclosure in the new bank regulating system Basel II on bank and bank customer. The effects are then discussed in a perspective of the economic man and information asymmetric theories. Furthermore is the Basel II effects on the capital adequacy of Andelsbanken för Åland examined.The approach of the study is qualitative and several interviews with individuals on different levels of the examined bank, Andelsbanken för Åland, have been carried out during the collecting of empirical facts about the effects of the regulating change from the Basel I system to Basel II.The research findings are as follows:Andelsbanken för Åland have increased its capital adequacy ratio from 12,7 percent to 14,4 percent, mostly due to lower risk weights on housing mortgages compared to Basel I. Andelsbanken för Åland have started to use a completely new credit risk and customer assessment system which classifies every customer and gives them a credit rating. The system cause a much heavier information gathering of the customers profile as well as a much better assessment of risk than the previous system, which the bank finds positive.

The requirement on audit was introduced when ownership was separated from management. The situation that arouse was that not only the owners, but also the stakeholders, required information about the company?s financial position. On this basis the audit would contribute to quality assurance of the financial information. One of the auditor's functions is to assess an ongoing stakeholder opinion.

In this degree project I write about how the farmers who grows carrots in Sweden get influenced by different rules, investments and demands. The Swedish agriculture are heading towards a harder time, and then you have to find new things to do. Now its hardly no profit to grow grain so you have find other crops. This paper is not a comparison between the contract cultivation to Findus and the cultivation where the farmer maked his products by a own company on the farm. If you have a small processing company on the farm, you have to increase the standard with different certificate. The farmer binds a lot of capital in machines, both field and in the process.

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.
