Arbetet bygger på att de informationssystem som används idag men som blir allt äldre och därigenom inte klarar de krav som ställs på dem. Detta medför att informationssystemen måste migreras till modernare plattformar, då företagen dels inte klarar sig utan dess nuvarande funktionalitet och dels måste vidareutveckla systemen.Detta arbete tar upp olika sätt som detta kan genomföras på och vilka problem som kan komma att uppstå när detta sker. För att kunna undersöka detta så genomfördes ett antal migrationer. Språken som migrationen kommer att ske mellan är Visual Basic 6 och Visual Basic .net. Migrationerna kommer att ske med hjälp av ett migrationsverktyg, samt ett ramverk som i arbetet skräddarsys för just arbetets typ av migrationer.Det arbetet kommer fram till är att det sker problem vid användande av ett verktyg och även att det inte ger tillräckligt med respons på vad som gått snett under migrationerna..

In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease. This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.

Every year more than 6000 thefts, to a value of 1.5 billion SEK, are reportedwithin the Swedish building trade. Plus all the indirect costs of having theconstruction site standing still.SafeTool is a newly started company that will try to prevent this problem witha modern technology solution.The key to SafeTool?s solution is RFID ? Radio Frequency Identification ? andthe solution looks like this;All tools are stored in a container on the construction site. Every tool isequipped with a RFID-tag that uniquely identifies the tool. With antennas in thecontainer it is possible to detect when a tool is leaving the container and whenit comes back.

This study examined the factors influencing dairy farmers´ decisions to invest in automated milking systems (AMS). The problem studied involves uncertainty, information and complexity for dairy farmers in specific decision contexts. The frame of reference in the thesis combines contingency theory and decision theory and is used in a qualitative analysis of a set interview with dairy farmers who have recently bought an AMS and salespersons from Delaval, one of the AMS suppliers.The aim of this study is to develop an understanding of the decision making processes of dairy farmers, and in particular to identify which types of factors influence the outcome of an investment decision in the technological development of a farm.The study uses Thompsons` (1967) theory about the structure that organizations develop to handle the input of information. Thus, interest is focused on how a farm business structure handles information in the AMS decision, investigating the differences in information with Delaval?s "feed first principle" system and Lely?s "free cow traffic" system.The results of the qualitative interviews with the dairy farmers who bought an AMS show that there are three important factors that influence the outcome: employees, suppliers and the owner.

The objective of this work was to evaluate and implement a number of energy saving functions for a specific embedded system. The functions were then grouped into a number of energy levels with known properties in terms of functionality, energy consumption, and transition time between the levels.The embedded system consisted of an AT91 ARM9 processor, GSM/GPRS modem, display, Ethernet and other peripheral units. Some energy saving methods that were considered were suspend to RAM, suspend to disk, frequency scaling, and methods for saving energy in the modem, Ethernet, USB and display backlight. The functions were grouped into levels and an interface was specified for controlling the energy level.It proved possible to get known properties within the defined energy levels, even though the paritioning of functions into these levels proved to be sub-optimal in a typical application usage scenario because it was designed for mainly energy consumption, not usage.The final result is a number of energy saving functions grouped into levels, which are controllable via an application interface. Each of the levels have a known energy consumption in both loaded and un-loaded mode..

The waveform of a radar signal affects the resolution in velocity and distance. The ambiguity function is used as an aid for analysing narrow band radar signals simultaneously in time and frequency. An analysing tool for wide band radar signals is missing.This thesis describes a generalised ambiguity function to be utilised for study of wide band signals. Waveforms are further synthesised with help of the developed analysing tool. The aim is to start with a certain ambiguity function and find a waveform that reproduces the same ambiguity function.Mathematical formulas are presented and implemented in Matlab to produce the wide band ambiguity function.

The main focus of this essay is to analyze whether strict employment protection legislation has a negative effect on the labour market possibilities for youth in the EU or not. To empirically examine the labour market possibilities for youth, data for unemployment rates and incidence of temporary jobs are used. By doing simple correlations between the different labour market characteristics and OECD?s employment protection legislation index the effect of the latter is tested. The result is that a tendency for youth unemployment and frequency of youth with temporary employment to be higher when employment protection legislation is strict can be seen.

The aim of this study was to determine which type of fluid to use in trauma care to improve patient survival. The method used was a systematic review, where a total of 18 studies were reviewed and 13 included in the results. The inclusion criteria used in this study were Randomized controlled trial, or studies relevant for the purpose, written in English and published during the last ten years. The studies were identified in the PubMed data base. The results showed that in trauma with hypovolaemia, colloid infusion has a better effect than infusion of crystalloid fluid on blood pressure and colloid infusion reduced the body's cascade systems in a beneficial way. Colloid infusion administered to head injury patients lowered their intracranial pressure more than crystalloid infusion.

Radio Frequency Identification (RFID) är en teknik som enligt många utsetts till framtidens teknologi inom Supply Chain Management. Detta då RFID, utan involvering av människan och utan behov av fri sikt, på distans kan utföra effektiva identifieringar av objekt. Det har emellertid, genom forskning, uppmärksammats problem med RFID och dess i vissa fall bristfälliga ändamålsenlighet inom logistiska sammanhang. Utifrån de möjligheter och hot som RFID innebär, har detta examensarbete kritiskt undersökt hypotesen: "Logistiska RFID-implementeringar är lönsamma och tillförlitliga". Analysen grundar sig på ett arbete genomfört vid Volvo Car Corporation (Volvo) i Göteborg och Olofström, där ett pilotförsök med RFID- utrustning för lång avläsningsdistans installerats och processeffektivitetsstudier fullföljts.

The purpose of this paper is to highlight the issue of preferential rights in relation to the increased practice of hiring temporary staff. The object is illuminated from a diversity perspective by seeing what a circumvention of the preferential rights may have consequences for vulnerable groups on the Swedish labor market. The question of preferential rights to reinstatement is controlled in  The Employment Protection Act. The preferential right is for the protection of workers made redundant due to redundancy. The use of agency workers has increased significantly in the Swedish labor market since the industry's legalization in 1993. This has created some problems in terms of preferential rights. To a circumvention of the law, shall exist requires that the measures constitute circumvention is justified, measures should have been sought to circumvent the law and been unfair in view of the particular case.

The purpose of this thesis is to examine whether Swedish, Internet-based travel agencies, acting on a consumer market are working towards creating added value for their customers. If that is the case, how and why do they use such a mode of operation.The theoretical framework was based on Grönroos´ ?Augmented service offering?, which treats added value as an addition to the core service. The services offered on five of the larger companies´ websites on the market were examined and 3 representatives of the five companies were interviewed.The study shows that 2 of the examined companies did not produce any added value, while 3 of the companies did produce added value for the customer. The added value was generated through packaging of core-, facilitating- and supporting services for the purpose of differentiating the company towards competitors and generating service fees..

A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.

The aim of this study was to examine the discourse of asylum seekers in Sweden from January 2009 to December 2013 in the newspapers Helsingborgs Dagblad and Dagens Nyheter. By using discourse analysis as a theory and method, combined with the theory of orientalism, I have analysed and compared news articles from these two newspapers. The findings of the study shows that asylum seekers are often portrayed as a group rather than individuals. Included in the group identity are several subgroups, for example asylum seekers are portrayed as victims, as a cost to society and as a highly suspect group that cannot be controlled. Furthermore, asylum seekers are depicted as ?the other? in contrast to the Swedish ?we?, where differences in culture and tradition are frequently mentioned.
