Deltagande i förändring : en förklaringsmodell av motivationsfaktorer till deltagande i förändringsarbete.
Hospital Mergers have been proved to be troublesome, the most crucial ingredient is believed tobe the participation of members of the organization on all levels. When the hospital mergerbetween the hospital of Malmö and the hospital of Lund is a fact, it seems clear that knowledgeabout managing motivation is important. The knowledge could also lead to increased possibilitiesto improve support for motivation where needed at the hospital.I have through a literature review created a descriptive model of the theoretical view onmotivational factors for participation in change and their relationships. The theoretical modelwhere then tested in a empirical study in which additional data created a more true model of themotivation on participation at the hospital.The findings of the study show how the descriptive model illustrates how the twodifferent departments both work with a empowering philosophy that have built in properties thatenable the employees to gain more motivation. The model also underline the importance of thecommunication role to enlighten the employee in what, where, when and why the change takesplace.
Är det svårt att hitta i en mobitelefonmanual? : En kvalitativ fallstudie om informationssökning och användbarhet
This master thesis states the following questions: Is it easy or difficult to retrive information from a mobile phone manual? How can the search process be described among user for a mobile phone manual? What similarities and differeces can be identified between users? Arhe there any variables that affect search performance such as reading skills or technical domain knowledge? Eight mobile phone users participated in an empirical observation and the scope was to find information in a paper version of a mobile phone manual according to given tasks. The results shows that some users has problems to retrieve information due to that the correct page in the mobile phone manual could not be located. The results show that the user is using several search strategies, for example the table of contents and the index, when trying to locate information. The results also revel that the user initiates multiple search steps before the correct information can be located.

GNSS-Styrning : Information för platschefer
An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

The society in which we live is controlled by various kinds of rules, both written and unwritten. These rules tell us not only how we should act as humans but also how we should act as women and men. Adults teach their children the rules of the society in various ways, but they also act as model figures. Children are influenced by conscious and unconscious actions and also by activities performed by the adults. Furthermore, adults write children?s books which bring the essential content into children?s lives.
Strukturkalkningens möjlighet att hindra fosforutlakning : en litteraturstudie
The purpose of this essay is to find out if liming with Ca(OH2) and CaO can reduce leachingof phosphorus from agricultural land and the problem with eutrophication. This purpose alsoincludes getting knowledge about how to make the phosphorus retained in the soil and beaccessible for the plants. This essay is supposed to show if more research is needed in thissubject. There has not been much research about this subject and therefore the amount ofmaterial to study is limited in this literature review. The research reports that have beenstudied have similar results.
Mätsystem för effektförluster i en högfrekvenstransformator
To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.
