Det finns huvudsakligen tre olika sätt att konstruera ett partitionerat system på: Federerad arkitektur, Integrerad Modulär Avionik (IMA) med ARINC 653 eller IMA med virtualisering. I den här rapporten undersöks de olika arkitekturernas egenskaper och vilka möjligheter som finns för certifiering av dem. Efter den teoretiska undersökningen har Virtualisering, och framförallt Xen, valts ut för en testimplementation och tillförlitlighetstester.Testimplementationen består av fyra partitioner där varje partition har sin specifika uppgift att lösa. Den fjärde partitionen används för att undersöka hur Xen hanterar en partition som aggressivt nyttjar I/O, processor eller arbetsminne.Testerna visar att Xen har en svag punkt: all I/O hanteras via en egen, speciell, partition. Denna partition saknar dessutom möjligheter att prioritera I/O från specifika partitioner.

Syfte: Syftet var att undersöka vad kommunikationsbrister kan bero på och hur en organisation kan gå tillväga för att lösa problem som uppstår på grund av dem. Med detta som grund har studien utformat rekommendationer för hur förvärvsorganisationer kan arbeta med den interna kommunikationen och på så sätt överkomma och förebygga brister i kommunikationen.Metod: En fallstudie utifrån en deduktiv forskningsprocess användes genom att ställa upp påståenden utifrån teorin som prövades på empirin. Datainsamlingen skedde genom kvalitativa intervjuer och en kvantitativ enkät.Slutsats: Brister som uppstår i kommunikationen har en verkan på hela organisationens finansiella och prestationsmässiga resultat. Genom att lägga beslag på kommunikationen kan en förvärvsorganisation bli mer framgångsrik..

Scania CV is one of the world's largest truck manufacturer. It is not only the directproduction of vehicles and methods that are important for Scania but also the servicemarket handling spare parts, repairs and workshops. The department Vehicle ServiceInformation construct standard times through work measurement for particularworks in the workshops. The software application STAM is used in the servicemarket to create and store standard times which then are exported to theworkshops' own systems.The purpose of this master thesis is to analyse and evaluate the internal workmeasurement system that includes standard times and the software STAM. Also,based on external analysis and benchmarking of other systems suggest appropriatefuture development within the area for Scania Vehicle Service Information.In order to perform the investigation, interviews and studies have been doneinternally at the departments that are involved in work measurement as well asexternally at Scania workshops.

The city of Uppsala and its surroundings are a very expansive area. A prerequisite for a sustainable development of the area is well-functioning supply of drinking water. In Uppsala municipality, the Uppsala esker and Vattholma esker are the groundwater storages for drinking water. Besides the eskers, other sources of qualitative groundwater in the Uppsala municipality are relatively poor and more than half of the area consists of ground conditions with a risk of saline groundwater. The neighbourhood of Vreta-Ytternäs is situated 10 km south of Uppsala, in the area with risk of saline groundwater but outside the municipal water supply.

Syftet med uppsatsen var att undersöka vad som gör att en användare vill använda SMS i en organisation och vilka faktorer som påverkar användandet av detta system, det vill säga acceptansen av att använda det. Då denna typ av system är relativt nya tyckte vi att detta var ett intressant ämne att undersöka, samtidigt som vi ville se vilka faktorer som påverkar användaren i avseende till användning av ett specifikt SMS-baserat system. Det kan även vara intressant för företag som vill implementera eller utveckla den här typen av system. Utifrån syftet bestämde vi oss för ett visst tillvägagångssätt som vi skulle använda oss av för att kunna få svar på våra frågor. Tillvägagångssättet var att leta i den litteratur vi haft på tidigare kurser inom det systemvetenskapliga programmet för att hitta en teori som kunde ge oss stöd för ett resonemang.

This master thesis describes the development of an UPS module. UPS is an acronym for Uninterruptable Power Supply. The UPS module has been developed at the company AerotechTelub AB. The UPS module delivers the necessary voltage and current in case of a power interrupt. If a power interrupt occur, the computer system has one to three minutes available to store data and shut down correctly.

Vad är det som gör att införandet av ett nytt IT-system i en organisation upplevs som framgångsrikt eller inte? För att söka svar på frågan studerades införande av ett nytt IT-system vid en svensk myndighet. Ramen för studien utgörs därmed av den offentliga sektorn och e-förvaltningskontexten. Genom att återge och analysera systemägares och användares berättelser om införandet och användandet gavs möjlighet att jämföra berättelserna med myndighetens intentioner med IT-systemet utgående från olika beslut och planer. Syftet med studien var att i den jämförelsen kunna fånga upp och bidra med kunskap om gap mellan olika perspektiv/berättelser vid införande av IT-system och utgående från det kunna visa på olika aspekter som kan bidra till förståelse av och förklaringar till upplevelser och resultatet av införande av nya IT-system i offentlig verksamhet. Studiens teoretiska ramverk baserade sig på idén om att IT konstrueras socialt och att man vid studier om informationssystem och organisationer behöver beakta både tekniska och sociala system/institutionell kontext.

Objective ? To study the requirement of nursing care of the equine patient during eye treatment with a lavage system together with a constant rate infusion pump. Procedures ? Three veterinary nurses at ATG: s Hästsjukhus in Skara were asked nine questions at individual interviews. Inclusion criteria for participation in the interview were that the nurse should have treated equines with and without the infusion pump to the lavage system, but also traditionally with eye drops. Results ? The equine had a higher well-being since it experienced less stress during eye treatment with the infusion pump compared to treatment given by hand through the lavage system. The treatment would be more effective with constant rate infusion and save costs for the owner.

The purpose of this Master Thesis is to analyze what suitable hardware platforms there are on the market in order to build a low price control and information system for mobile applications, called small display module. The thesis will be underlying material for making a decision for further development. The result of the thesis consists mainly of a Windows CE kernel and a schematic for a CPU card, on which it would be suitable to build the display module. Another major part of the report is the introduction of different techniques that could be of interest when designing a processor based system. The processor architecture that was chosen is the x86.

Emwiro Vibe is a complete system for seismic measurements. The functionality of the system was before the completion of this project handled using a software contruction based on a state machine. Emwitech, the company developing Emwiro Vibe, expressed a desire to replace this solution with a real-time operating system (RTOS). The project consisted of two parts. Firstly the existing software was studied, available RTOSes was evaluated, and the RTOS most suitable for the application was selected.

The paper?s focus is on Max Hamburgarerestauranger AB?s incentive system, that is directed to the managers of all of its restaurants.We had interviews with the CEO, as well as the head of the Economics Department of Max H.

The purpose of this thesis is to examine and analyze the characteristics of the management control system private equity firms use to manage their portfolio companies. The thesis takes a share holder value perspective, and it is assumed that the goal of the management control system is to increase the shareholder value in the portfolio company. In a qualitative study two private equity firms and two portfolio companies, one for each private equity firm, were studied in detail. In total, nine in debt interviews were completed. The results from this study suggest that the characteristics of the control system are dependent on the surrounding context; the focus on shareholder value and the specific characteristics of the private equity industry shape the characteristics of the management control system.

Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB. Certain issues have been chosen for further studies.In order to identify the consumption of compressed air at PM 8 and 9, several measurements were made. At PM 8 there were not found any pressure drop, only large pressure variations for short periods of time. The causes of these pressure variations were not established.

The Scanian woodfences has been determined by two mainly elements: Scania's composition of tree species, with a large element of deciduous forest, and the local building tradition which has more in common with the European continent than the Swedish tradition. By examining responses from ethnological question lists deriving from the first half of the 1900s, combined with literature studies, I have been able to deepen and broaden the knowledge behind the various fencing design. In addition I ?ve constructed maps which could illustrate their historical geographic distribution.I have come to the conclusion that there was three main types of woodfences that was most common until the barbed wire was introduced in the early 1900s and later on replaced the elderly woodfences. Common for the three main types is that the base material was made out of Juniperus communis, this largely because of its durability against rot.
