We investigated a retirement home, where we looked at whether there are differences, disagreements or conflicts between teams who work day and night shifts. Our purpose was to examine the Heads of Unit and the employees perspectives on their perceived work situation, cooperation difficulties and why they emerged. We chose the general systems theory as our theoretical basis, which gave us the opportunity to highlight different parts that can affect the working climate and the cooperation of the working groups. The study also highlights the importance of structure, common goals, reporting and dialogue meetings. To understand the perceived work situation, we used methodological triangulation, using quantitative and qualitative methods (surveys, semi-structured interviews).

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications. A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM. The case study showed that Intent Specifications and CBSE could successfully be combined.

This master thesis project will describe and evaluate the interfaces between applications and Controller Area Network, CAN, interface boards from different manufacturers. The interfaces have corresponding functions but the usage of parameters is different. The simply communication of sending and receiving messages is more alike than the supplementary functions between the different interfaces. The CAN communication is more controlled by the CAN protocol and is therefore more alike. The evaluation shows differences and similarities between different interfaces and also difficulties and options to translate them.

This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.

This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.

When investigating mechanical problems it is often more convenient to deal with scalars rather than vectors. In this project methods stemming from the field of analytical mechanics, which lets one derive the equations of motion using scalar quantities instead of vectors, have been used. Two mechanical problems were investigated, a double pendulum with a spring and particles orbit in a sphere. The equations of motion of the two systems were derived with the assistance of computer algebra, using Maple and the external package Sophia. The systems were investigated with regard to periodicity and conserved quantities..

The aim of this study was to investigate how seasonal variations affect the quality of logging residues. The study was hosted by VIDA Energy. Logging residues can be processed and transported within different systems. Today the dominant systems are chipping at landing and bulk transportation of logging residues. In these systems the handling of the logging residues are carried out in the same manner up to the landings. Moisture content at the time of chipping is the primary quality parameter. Fine fractions of logging residues are strongly dependent on moisture content in storage.

This thesis examines the approach for implementing strategy that has been applied by the study object, Svenska Spel. The specific approach originates from the theories of Elliot Jaques, whose key proposal is that individuals have different capability of carrying out tasks over different time-spans. The main purpose of the study is to analyze how the approach has influenced the management control systems in use, in order to ensure that the strategy is successfully implemented on corporate as well as operational level. Twenty in debt interviews conducted with employees, representing a vertical cross section throughout the organization, are the main source of the study?s empirical foundation.

The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation. The possibility to protect oneself against attacks from the outside becomes increasingly difficult.

Denna rapport sammanfattar resultat av ett examensarbete på en högskoleingenjörsutbildning som utfördes av två studenter på Malmö högskola. Arbetets syfte var att genomföra en mängd olika experiment med accelerometer, barometer och GPS i en modern smarttelefon. Ett antal scenarier för en tänkbar sensoranvändning i applikationer formulerades för att vägleda olika experiment. Experimentdata dokumenterades noggrant och analyserades med avsikten att skapa en databank med information för framtida studier. Analys av data inkluderar höjdbestämning i naturen och i byggnader med hjälp av barometersensor, geografisk position med hjälp av GPS, hastighet och acceleration under en hissfärd med hjälp av accelerometer. Rapporten innehåller en omfattande litteraturstudie om användning av sensorer vid inomhuspositionering. Från analys av mätdata, kom vi fram till slutsatsen att är möjligt att beräkna höjden från barometerdata med bra noggrannhet under optimala omständigheter. GPS höjden från mätningarna har stor felmarginal jämfört med den verkliga höjden samt när den jämförs med den beräknade höjden från barometern. Genom att utföra en numerisk integration på accelerometer-data kom vi fram till att det är möjligt att beräkna ungefär hur långt man har färdats med en hiss, dock att vissa detaljer måste tas i beaktning..

To be able to feel a sense of belonging, people need to have the possibility to take part of the information from the society. Hearing-impaired don?t have the same possibility as hearing people when they want to take part of the information, therefore they don?t get the same benefit. This contributes to a feeling of not belonging and a sense of limitation in different social occasions. Therefore the society needs to be accessible to everyone regardless disability.

The purpose of this study was to examine the routines of performance related pay systems in two Swedish municipal upper secondary schools. A second purpose was to examine what data was included for evaluation of a co-worker?s performance and how a principal collects data. The purpose was also to examine a principal and teachers´ view of performance related pay systems and if it was possible to note an agreement. Principals have been interviewed and teachers have answered a questionnaire to fulfil the purposes of this study.The study shows that the municipality had a good routine that included individual discussions with co-workers about their salary and had fixed municipal criteria.

Computers and business systems are used more frequently in a world where IT gradually is taking over. This is also true when it comes to the real estate valuation process where actors on the Swedish real estate market are using automatic valuation systems for real estate appraisal. But the real estate agents have not yet seen the charm in using these automatic valuation systems for real estate appraisal. Can the real estate agents also use the automatic valuation systems? We developed our three main subjects: the valuation process, an automatic valuation system and the real estate market with assistance from scientific articles.

The purpose of our study was to examine 13 to 14 year olds experience of bullying from a perspective of human developmental ecological systems. The questions at issue were: How do the young people themselves define the concept of bullying? Which own experiences do the young people have of bullying? How come bullying exists according to the young people? How do the young people experience that their surroundings view bullying? What do the young people consider that you can do about bullying? We used a qualitative method to collect and handle our primary empirical data. We did individual interviews with ten young people.The results of our study shows that the majority of the persons interviewed thought people bully because they have bad home conditions and that they are unsure of them selves. Many of the young people talked about three different groups in a school class: The popular, the less popular and the nerds.

The purpose of this essay was to compare the Swedish and the Japanese pension system and see if there were any big differences or similarities. I was looking for answers to such questions as if the systems were modelled with the problematic demographic situation in mind and also how these two countries had tried to manage the problems. Path dependency was also a central conception when I studied the reforms of the two pension systems. I mainly used literature and Internet sources in my study. There were many books on the Swedish pension system and the debates that had been going on since the 80's.
