Denna rapport består av information och data som har samlats in i syfte att kunna presentera en genomförbar konvertering av linfärjan Toras framdrivningssystem, som idag utgörs av dieselelektrisk drift, till bränslecellsdrift. Den bränslecell som behandlas i rapporten är PEMFC och är en bränslecellstyp som drivs av ren vätgas. Resultaten tjänar som en informationskälla för en potentiell konvertering och presenteras för Trafikverket, som ett alternativ i linje med Sveriges regerings mål att reducera mängden CO2 utsläpp på en nationell nivå. Informationen i rapporten har insamlats via mail- och telefonkontakt samt ett besök på Tora på plats i Stockholm. Ett genomförande av konverteringen är fullt möjligt men mer kostsamt än dieseldrift i dagsläget med avseende på höga bränsle- och inköpskostnader utav bränsleceller.

S2 CRM is a Customer Relations Management system built in classic ASP that runs on a web server servicing customers with varying needs. The purpose of this thesis work is to convert parts of the system to the web development environment ASP.NET. The purpose is also to gain knowledge of the framework itself. The ASP.NET environment is compared with another framework, JBoss Seam, in order to understand the differences and to evaluate the possibility of using another framework than ASP.NET, when building the new system. The outcome of this comparison is that although JBoss Seam is just as good, and in some aspects better than ASP.NET, the use of ASP.NET simplifies the continuation of development on the S2 CRM product.

The data acquisition system COMET developed by Saab AB contains a unit for signal conditioning and A/D conversion, called KSM. The varieties in signal conditioning constitutes of a number of specific PBAs and maintenance as well as reconfiguration of these are complicated not to mention costly. This thesis has aimed to investigating whether the signal conditioning circuits can be replaced by a general purpose, programmable solution. If so, how can this be done? The development has been carried out by evaluating ideas through the use of a laboratory environment and has resulted in an analog design for laboratory purpose.

In this thesis work a Geographical Information System (GIS) based methodology to identify locations suitable for the installation of wave energy converters has been developed. Parameters of importance have been identified and a GIS-database has been set up, containing data about the marine environment. In a case study of the Swedish west coast the methodology has been applied, resulting in a number of maps showing possible areas. The results show that large areas are suitable for installation of wave energy converters, from a technical and economical point of view. When consideration is taken to other interests in the area, such as navigation, fishing and environmental protection, the size of the suitable area diminishes considerably.

On today?s competitive market, it is difficult to achieve profitability trough high prices on manufactured products. Profitability must be obtained through low manufacturing costs, high quality and short lead times. One of the companies on the market is Sandvik Coromant, manufacturer of tools and chips for metal cutting. This master thesis investigates the methods of manufacturing for boring bars at the manufacturing unit GVH4 at Sandvik Coromant in Gimo, Sweden.

Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

Syfte:Att kartlägga om en förändring av ett företags kassaflödescykelpåverkar räntabiliteten för företaget. Dessutom undersöks omkassaflödescykelns längd kan säga något om branschlika företags lönsamhet och om omsättningsförändringar påverkar ett företags kassaflödescykel och räntabilitet. Metod: Vi har gjort en kvantitativ undersökning baserad på empiriska data från 11 utvalda företags årsredovisningar. Linjära regressioner har utförts för att fastställa om det finns några samband mellan kassaflödescykeln och räntabiliteten. Slutsatser: Vi har inte hittat några signifikanta samband som stöder deetablerade uppfattningar som finns om att ändringar ikassaflödescykeln påverkar räntabiliteten.

This thesis studies the stock price reaction around 68 announcements of special dividends and share redemptions on the Swedish stock market between the years of 2003 and 2007. We show that for the Swedish private investor, the tax effect of a share redemption is lower than that of a special dividend. Moreover, a share redemption could be interpreted as a signal of undervaluation. These two factors lead us to assume that the stock market would react more positively in connection to the announcement of a share redemption. We test this hypothesis through an analysis of the risk-adjusted abnormal return for the observations in the sample.

The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive. The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of association analyses.

Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.
