Test bench for air bearingsThis thesis work consisted of bringing forward and defining the test parameters relevant for a test bench and constructing a test bench that can test and verify the largest existing air bearings that are of use in Micronic Laser Systems AB machines. Because the knowledge about air bearings is limited it is thought that with the help of the test bench the knowledge would increase and in that way improve the air bearings.After learning more about air bearings and their purpose at Micronic Laser Systems AB, I started the concept phase for the test bench. For each part in the test bench I consulted my two tutors, Torbjörn Hedevärn and Johan Bergqvist, at Micronic Laser Systems AB. The final concepts where documented as 3D-modells in Solidworks and some of them have been tested in Solidworks FEM-program.The test bench is designed so that, with the help of a pneumatic cylinder, 25 kilo weights are placed on the air bearing to test its stiffness, damping and the pressure performance under its surface area. To test these parameters the test bench has to have a pressure meter, accelerometer and a microcator.

System Andersson AB is a company located in Jönköping that works with developing computer systems for the mechanical engineering industry. As of today, when this report is written, the company is working on the development of a new Manufacturing Planning and Control (MPC) system. This new system aims to create not only a user friendly interface but also a modern, stylish interface. To achieve this, the company has decided to work with a, for them, new application framework; Windows Presentation Foundation (WPF).System Andersson is well known for developing systems for different kinds of touch screens, this project is no exception. For this new user interface the company wishes to implement different types of Drag&Drop functionality.

The aim of the study was to through a qualitative method with two focus groups investigate how young women percieve that their identity creation is influenced by them reading celebrities Blogs and in that case, whether this type of Internet activity affect their autobiographical memory, the foundation for personal identity. Since the main task of the autobiographical memory is to give the ego and its social mode a foundation by sharing memories with others, the Internet activity should be seen as an important factor for the identity formation of young people. Today, the young spend equally mauch time being connected to various media as they do socializing with family and friends. The results indicate that young women view the world and lifestyle that known Bloggers expose intheir Blogs as a kind of ideal. The young women got an aha reaction when they realized that what the Bloggers expose is not always equal to the real life..

My essay is about a dilemma that came up on a preschool that I worked in. My purpose with my essay is to examine and to get an understanding for what children with attachement and separation anxiety goes through, and how a preschool teacher the best way can help them.The background story is about a boy named Sixten (not his real name). When separated from one of the preschool teachers Sixten exhibits a great deal of separation anxiety. In the story I give some clear examples of situations where Sixten displays this separation anxiety. I have in the essay viewed it from different perspectives and I have questioned my own role as an educator, but also my entire team.

Baled silage has become one of the most important conservation methods in Sweden. Because we take our grass as silage we get the quality and the good hygenic that we would like to have. Silage has become a big buisiness also in the horse feeding where many of the breeders have changed from the hay to the hay-silage. The difference between regular silage and haysilage is that the hay silage is dryer (60-70%DM). The hay-silage has also put higher demands on machinery and wrapping material since the grass gets sharper and harder to press together real hard. The main reason for the test was to compare two different systems for wrapping, the new Cross Pac and conventional.

Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigated in the report. .

The purpose with this bachelor thesis is to identify risks and insufficiencies concerning the production at WilloMaskin AB. The project is limited to only 4 machines, where theories as ?OEE? (overall equipment efficacy) should be illuminated and analyzed. The theory of ?Single Minute Exchange of Die? is also presented.The method used in this project is mostly based on qualitative studies but also quantitative studies are presented.

Sara Lidman?s second novel Hjortronlandet (1955) unfolds in the north of Sweden in the early 20th century. It describes the progress of modernity and the conflicting interests of an old local culture and a new more ?civilised? one. The two cultures are constituted by different value systems and in the novel they are represented by two neighbour communities.

Cross-suckling, i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of knowledge regarding cross-suckling increases. The overall aims with this thesis was to investigate how sow behaviour and productivity are associated with the occurrence of cross-suckling, and to investigate consistency in sow nursing behaviour related to cross-suckling. The study included information about the first 4 parities of 40 LxY sows kept in outdoor and indoor production environments. Sows were single housed the first 2 weeks after farrowing and group housed (4 or 5 sows per group) from 2 weeks after farrowing until weaning, 7 weeks after farrowing.

The purpose of this essay is to acquire variables that explain and may be used as a base for wage estimation in the private sector in Sweden. The factors that are assumed to have an impact on wage estimation are based on earlier Swedish and international studies. Business survey data, which is based upon monthly questions to firms in various sectors of the Swedish economy posed by the Swedish National Institute of Economic Research, will be analyzed to find out weather they have an impact on Swedish wage settings or not. Tests including business survey data are yet rarely frequent, why this essay will be some kind of a pioneer within the area. To estimate significant factors that influence wage setting in Sweden, three different wage equations have been modeled and tested with a regression model.

The aim of this study was to quantify the productivity and the costs of different harvesting systems (teams), containing harvesters equipped with accumulating harvester heads and forwarders, in first commercial thinnings were an integrated harvest of pulpwood and energy wood were performed. In the beginning the plan was to study and measure 20 sites before and after harvest. Due to storms during the summer of 2010, complete data could only be obtained from 8 of these 20 sites. Seven of these sites were privately owned and one was owned by UPM, all of the sites had been pre-commercially thinned. The mean stem density before harvest was 2578 stems per ha and the mean stem volume was 0.074 m3solid over bark.On average 1518 stems/ha was harvested.

This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.

I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has. The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time. I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today. What is drag hose system? You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.

This report is the final part within our education, Industrial Organization and Economy focusing on Logistics and Management at Jönköping School of Engineering. The aim with this report is to coordinate recycle drives for deposited aluminum-cans and bottles collected from grocery stores within Jönköping county and locality.In the present situation both aluminum cans and bottles filled with drinks are distributed to the grocery stores by the brewery?s own distributers. At the same time as they supply the drinks they also discharge the grocery stores units with restored aluminumcans and bottles. To make it easier for the grocery stores to handle the goods in the future, all distribution of drinks ought to be directly delivered to the grocery stores own separate central warehouse.

In recent decades here has been a huge development in information technology (IT), where we humans are increasingly using IT in our daily lives, ranging from social media to music streaming services; this has also been a reflection of the technologies developed to our cars. Infotainment systems have become an increasingly regular feature in modern cars where the high degree of integration such as navigation, mobile and Internet has become more common and more sought after. Despite this, relatively little research problemized User Experience of a complex infotainment system in a car. This study thus has the intention to consider the relevance of reality based tests by examining how the user experiences a complex infotainment system in a car. We asked ourselves; How do the user experience a complex infotainment system in a car? We conducted our qualitative study, an interview with researchers in the field of vehicle and road safety and designed a number of system-related activities in a test session where we observed three users.
