For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

The trend towards increasingly large farming units raises questions regarding how to better monitor production. Larger units make the impact from possible errors more severe, which increases the pressure on management supervision. To cope with management issues, prevent errors and handle increased demands on traceability and documentation, the Real Time Location Systems (RTLS) concept is making its way into various parts of agriculture. In sectors outside agriculture, RTLS are already being used successfully to track and locate items through nodes at different levels of accuracy, such as room level or the relative or absolute position. Empirical data can be received in real time from the nodes.

Claw diseases are common diseases in modern dairy production. They are painful for the cow and costly for the producer. Differences in the prevalence of claw disease depending on housing system have previously been observed. This raises the question if there are genotype by environment (GxE) interactions for claw diseases in different housing systems. To investigate this claw trimming records for Swedish Red dairy cattle (SR) and Swedish Holstein cows (SH) were retrieved from the Swedish Dairy Association.

The aim of the study was to evaluate the social integration amongst newly arrived students in the two different school systems Sweden welcomes them into. The first school system takes in newly arrived students into preparation classes whilst the other integrates the students directly into ordinary classrooms. The examination is based on qualitative observations in the classroom, canteen, and playground, and interviews with teachers and a select few students from each school system.The result of the study showed that newly arrived students in ordinary classes are socially integrated more into the school than the newly arrived students that are welcomed into a preparation class. Newly arrived students are offered a larger chance of being integrated into the school environment if they are introduced directly into an ordinary class. In preparation classes, social integration is narrowed down to between the classmates.

Examensarbetets mål är att bygga en Quadcopter som kan flyga och styras via en radio-sändare i alla riktningar, stabilisera sig själv i luften, kunna landa autonomt och den skall även motverka krock i framåtgående riktning.För att uppnå grundmålet att kunna flyga så implementerades en PID-kontroller som används för att stabilisera Quadcoptern i luften genom att reglera motorer efter sensor-orientering. Denna sensororientering fås kombinera vinkeldata från en accelerometer och ett gyroskop.För att uppnå målet med autonom landning så användes en ultraljudssensor. En egen algoritm utvecklades för att läsa avstånd från marken. Avståndet från marken användes som grund för att skapa en egen algoritm för den autonoma landningen.Quadcoptern kan i slutprodukten stabilisera sig själv i luften, styras via radio och landa autonomt. Säkerhetsfunktioner som att aktivera autonom landning ifall Quadcoptern kommer utanför radions täckning är implementerade och även en brytare som stänger av motorerna.

The purpose of this essay is to study uses of history in a complementary teaching material in the subject of history. The material in question is a 170 page book titled Hitler och Stalin- En bok om ondska. In English, ?Hitler and Stalin- A book on evil?. Essential to the study is that it is expressed within the material that it might be used as the basis for a discussion of the threats against an open democratic society.

This thesis is carried out at Portsystem 2000 AB who manufactures and markets industrial doors and docking systems. The background to this thesis is that the company?s management considers that their follow-up process of cost accounts is not fully functioning.The aim with this report is to investigate and describe the present procedure of the follow-up process concerning the time of operations and come up with suggestions for improvements. This thesis is performed within the range of the following areas: Information systems, quality, processes and cost calculation. The main method we used were semi structured interviews with a fairly opened framework.

This study was conducted at VikingGenetics' bull breeding station in Falkenberg, Sweden. The bulls waiting for the results of their progeny testing at this station are either kept in group housing or individual housing. Since both of these housing systems have advantages and disadvantages, it was in the interest of VikingGenetics to know which of these housing systems is the best. The aim of this study was to investigate the welfare of the bulls in these two housing systems through behavioural observations and the use of activity monitors. In the preparations for the study 16 bulls, 8 in each housing system, were chosen.

This is the final documentation of the basis that can be the foundation of how to solve theproblem with leaking hydraulic oil in a shoe press at the company Albany InternationalAB in Halmstad, Sweden.The project has been performed at Halmstad University as a degree project commissionedby Albany International AB. The purpose of the degree project was to find a way ofdetecting the hydraulic leak of a shoe press. The reason is that the shoe press runsunattended during nights and weekends, this can cause an extensive decontaminationwork and production stop if leak. The hydraulic oil could be leaking in large amounts orslowly as a fine mist. The development of a working system that can detect a hydraulicoil leak and stop the machine before a large amount of hydraulic oil leaks out wouldconsiderably reduce the cost of the decontamination work.

This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".

The purpose of this thesis work was to develop an automatic fault detection system for surveillance of bearing temperature in hydropower turbines. The parameters used except the bearing temperature were cooling water temperature and cooling water flow. A simple static model based on data sampled every minute was developed to estimate the bearing temperature. Then a detector for detection of change in bearing temperature based on the CUSUM-algorithm was designed. Since the amount of data was very small the developed model was too uncertain to be used in a working system.The designed fault detection system showed to work well for the available data.

Milkability or ease of milking, has higher importance today for Swedish dairy cattle producers after the introduction of milking parlours and automatic milking systems. Milkability is the cow?s ability to quickly milk out and be completely milked. There are several measures of milkability available. Today the farmer measures the traits subjectively in relation to the conformation scoring of the cow 30-270 days after her first calving.

The purpose of this report was to compare Lilluns egg production with other Swedish egg producers based on the flow of nutrients (nitrogen, phosphorus and potassium) in the egg production systems. The main focus in the report was the utilization rate of the forage and the excess of nutrients per kg egg. Additionally, the purpose was to identify the environmental impact from Lilluns egg production and compare the results with other egg producers. The inflow of nutrients associated with forage and poultry was compared with the nutrients that were exported from the production. All of the egg producers in this study had an excess of nutrients.
