With the huge amount of computers connected to the Internet the IP-addresses are starting to run out. The Internet Engineering Task Force, IETF, have decided that it is about time to exchange the old 32 bits Internet protocol, Ipv4, to a more modern 128 bits protocol called Ipv6. This thesis explores the possibility to install Ipv6 in different operating systems. By testing various operating systems and by set up criteria compare them to each other we give the reader a picture of how the installation is done. We also show which operating systems to prefer if you want to use IPv6.

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

In the country of Jordan, egg production is very important economically, but several bacte-ria are involved in food borne diseases transmitted from eggs or other poultry products. The most important are Salmonella spp., Campylobacter jejuni and Escherichia coli. In Jordan two different housing systems are used for hens in large scale egg production; con-ventional cages and litter floor systems. Eggs from four different farms were analysed and compared to see if a difference could be found regarding the presence of pathogenic bacte-ria on the egg surfaces between these two systems. Total number of aerobic bacteria was analysed, the presence of Salmonella spp., C.

The purpose of this essay was to study how youths think about their youth and future. Our intention was to study in which order of priority today's high school students in Helsingborg ranked family life, education, career and vagabonding. We also investigated what the term adolescence meant to them.Our main questions were how our respondents looked upon their youth and their future. In which way did they give priority to family life, education, career and vagabonding and why did they give these priorities? Which meaning did the respondents lay in the term adolescence?The study was based on interviews with seven young people, studying at a communal high school in Helsingborg.

The purpose of this thesis is to analyze the design and function of an engine production management?s control system and its intended function, and to contrast it with the present management control systems in use on an operational level. Interviews conducted with employees from all levels of the engine production are the main source of this study?s empirical foundation. Information has also been gathered from relevant written material such as annual reports, internal documents etc.

A manufacturing machine at the engineering company Sandvik Coromant has a positioning table which task is to move an item linearly. The positioning table has a linear motor capable of high velocity and acceleration. This makes it possible to achieve short cycle times and a more profitable production.The purpose of this thesis is to bring forward a new concept which is more adapted to the requirements of the positioning table. The reason is that the current positioning table provides an unnecessarily positioning accuracy of 0.01 mm, while the requirement for the positioning accuracy is just 0.1 mm. The goal is to reduce manufacturing and component costs.To develop a suitable solution an approach for the concept development process has been performed.

The study aimed to investigate the acute medical chain consisting of SOS operator, ambulance nurse, emergency nurse and emergency physician with regard to the assessment and prioritization of the victim.The design of this journal study is retrospective with descriptive approach. Data were collected from all ambulance missions carried out in Uppsala county 2009-01-01 between the hours 00:00 to 12:00. Sample period was chosen because the prerequisite for high frequency on the ambulance mission was supposed to be good. In order to be able to systematize the compilation of data a protocol were prepared and used. Applicable data were collected from three databases SOS Alarms, ambulance operations, and the University Hospital in Uppsala.

This study is focused on small scale water and wastewater handling in Sweden. The study is divided into two major parts; the first describes common methods for water- and wastewater handling and the second part is a case study on three small and expensive systems in Gällivare municipality, in the north of Sweden. In the case study, abilitys for the local government to hand over unwanted systems to the water users is investigated and found to be a plausible solution to cut costs for two out of the three studied systems. In the third case, water and wastewater systems is not recommended to be handed over but other ways of cutting costs are suggested..

Certifications is common for IT in relation to individual program languages or program applications. Certifications for educations that endures several years is not as common to see. In this paper the situation for the Systems Science programme is researched, by investigating how the programme looks around in Sweden. Also by using interviews, show how companies and people responsible for the programme in Umeå, think the contact is between them and how the knowledge of the Systems Science students are from the view of the companies that employ them. In the end the conclusions show that there are differences in the Systems Science programme, and that the companies have quite a similar view of what the Systems Science students are good and not so good at.

The computer consultant company Create in Lund AB wishes to facilitate their invoice routines, as it at present is required that the administration finds and compares information from two different systems.The purpose of this thesis is to develop an invoice management system that simplifies the invoice management process for the administration at Create. During the development of the system, I have chosen to follow the software development process Unified Process and also tried to find design patterns that can be applied to the integration.The result of my project is a self-contained application developed using the Java programming language that communicates with the databases of the other two systems and presents relevant information to the user as a set of invoices. Of the 23 design patterns I studied, I used four of them in the invoice management system. However I couldn?t find any connection between any design pattern and the integration of systems.

The increasing administration in IT-systems is the target of much debate today. It is viewed as taking time from what is considered to be managers? real tasks as well as resulting in an ineffective and stressful work environment. This view of IT-systems as problematic and time consuming can also been found among unit managers in a municipality in the north of Sweden. To be able to understand why IT-systems are perceived in this way this study?s aim has been to find what leads to this view.

The purpose of this report is to collect, compile and complement the scientific and experience based knowledge concerning high pressure fire fighting today. The goal is to produce a decision data for the Rescue Service concerning the use of high pressure systems for fire fighting. Focus is on hose reel high pressure systems but other systems are discussed too. The report begins by describing the technical properties of the different systems. Then the fire fighting properties are evaluated, including manoeuvrability and safety for users.

The aim of this study was to compare the Query-by-Humming systems Midomi, Musicline and Tunebot regarding their retrieval effectiveness. The aim was to see if there were differences between the systems but also between the user groups common users, musicians and singers. Query-by-Humming system means that the user sings a tune that the system then use to find the right melody.To compare the systems and their users, queries where collected from the different user groups and replayed for the systems. Mean Reciprocal Rank and Friedman test was used to do the comparison.The results showed that the system did not achieve equivalent and that there were no difference between the user groups. The Mean Reciprocal Rank showed that the systems had very different retrieval effectiveness, where Midomi was the system with best result and Musicline with the lowest result..
