Since long, Sweden has had exceptionally low calf mortality compared to most other countries. The tradition has been to keep calves in individual pens. With increasing number of cows per herd there is now a larger interest in more efficient and economical group systems for housing calves. However it has been noticed that bigger herds have more health problems and higher calf mortality than smaller herds. The early signs of disease are harder to detect when the animals are not fed manually.

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

This thesis serves to examine how manufacturing SMEs consider outsourcing. Furthermore, we aim to identify the main characteristics and patterns for these types of companies that can explain their rationale in such a decision. The chosen method for this thesis is abduction and selected research approach is multiple case studies. Seven case studies have been conducted at EAB AB, Esbe AB, Hörle Automatic AB, Pelly Industri AB, SGV Industrier AB, Swede-Wheel AB and Wulkan AB. Our findings have illustrated that although traditional outsourcing theory provides a good platform for explaining the rationale behind outsourcing decisions in SMEs, we have identified additional considerations that SMEs, operating as 2, 3 or 4-tier suppliers towards OEM-corporations, make.

Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.

This paper describes the design and implementation of an automated build system for the JAS39A simulator FUS39A at HiQ:s offices in Arboga. The assignment was to automate the process in which modules are built; the simulator is composed of a number of modules which are built manually at the end of each week, this process takes about a day of manual labor. The system can automatically build a module as either a scheduled service or by manual invocation. The system contains functionality for reporting the build results to any given recipient by e-mail. The purpose of the system is to free up the time put into manually building the modules for better suited tasks by automating the build of FUS39A.The assignment was split into two parts, an analysis part where information of the old system was gathered, tools and methods were chosen and the new system was designed.

Since feeding fodder crops to dairy cows is a heavy and time-consuming but often disregarded line of work, this study wishes to view the different possibilities that are currently available to decrease the time to feed and apply this knowledge on an existing farm. For this purpose, four farms have been studied due to what feeding systems that are currently used and how long time the feeding required. The occurring systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer which fills an automatic feeder.

Huvudsyftet med det här examensarbetet är att se om det finns ett skäl eller behov att skapa ett serviceföretag inom IT och finna affärsmodeller för detta företag. Vidare avses utvärdera dagslägets hantering av IT hos små till medelstora företag. IT har blivit viktigt för företagsverksamheten men kan lätt försummas i mindre och medelstora företag Vi vill genom en marknadsundersökning se om det finns ett behov av ett serviceföretag. Därtill genom en undersökning av existerande teknologi och öppen mjukvara utvärdera om ett serviceföretag kan skapas för hantering av IT hos dessa företag. I vår undersökning fann vi vissa företag som är intresserade av vår lösning och vi fick svar på en del av våra frågor om hur situationen ser ut för företag inom Gävleborgsområdet.

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..

The aim of this literature study was to analyze how milk urea concentration is working as a measure of the nitrogen supply to rumen microbes and indicator of the environmental load. Questions included in this literature study were how to improve the dairy cattle nitrogen efficiency and what correlations there are between milk urea, nitrogen efficiency and crude protein content in the feed. Effects on the reproduction from high ration protein content are also addressed. Dairy cattle are today fed with large proportions of protein which could lead to high expenditure of feed and environmental pollutions. The nitrogen can be lost to the environment by different pathways; leaching, denitrification or by emission to the air.

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

Communication is a part of everyday life. The more sensitive information we handle, the more interesting the question around security of your information becomes. There are two ways of handling security around the information you want to communicate, either you control the means by which you are communicating. Or you control the way you communicate, making you able to use existing communication channels. Existing methods within cryptography enables two parties to communicate information securely.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..
