This is a thesis project done on behalf of BillerudKornäs in collaboration with Örebro University in a research project investigating grip stiffness of carton board packages. This is of interest because a better understanding of it would allow optimizing of the packaging design and result in a better product. In this thesis the mission has been to develop a setup for a sensor enabling a method of testing on packages. This has been carried out as a product development project. After a preparation study a specification of requirements was written. With the use of this a number of concepts were generated. Through evaluation one concept was chosen for further development and built as a prototype model. The prototype did not work satisfactory at the end of the project but could with some improvements be useful in testing packages with the intended sensor. / Detta är ett examensarbete utfört åt BillerudKorsnäs i samarbete med Örebro universitet inom ett forskningsprojekt där greppstyvhet hos kartongförpackningar undersöks. Det här är intressant eftersom att en djupare förståelse inom området skulle möjliggöra optimering av förpackningsdesignen och resultera i en bättre produkt. Uppgiften i detta examensarbete har varit att utveckla en testrigg för en sensor med syfte att möjliggöra en laborativ metod för att testa förpackningar. Detta har bedrivits som ett produktutvecklingsprojekt. Efter att en förstudie gjorts togs en kravspecifikation fram. Med hjälp utav vad som definierats i denna generades ett antal koncept. Genom utvärdering valdes ett koncept för vidareutveckling och byggdes sedan som prototypmodell. Prototypen fungerade inte tillfredställande vid projektets slut men skulle efter vissa förbättringar kunna vara användbar vid tester av förpackningar med den avsedda sensorn.

This experimental study investigates the second language acquisition of the four Mandarin aspect markers -le, -guo, -zhe, and zai- by native Swedish university students enrolled in Chinese language courses in Sweden. The main points of inquiry are acquisition order, the Aspect Hypothesis, the Distributional Bias Hypothesis, and the Prototype Model. The study contains a cross-sectional study and a longitudinal study. Both written and spoken data are collected. The tasks in the cross-sectional study include film-retelling, picture-retelling, grammaticality judgment, fill-in-the-blank questions and comprehension. The longitudinal study includes written data produced by seven students in their tri-monthly journal. The study shows that perfective markers are produced before imperfective markers. The results of the experiments are consistent with the Aspect Hypothesis. The Distributional Bias Hypothesis can account for most of the Aspect Hypothesis but there are exceptions that indicate that other factors could also influence the acquisition process, such as L1 transfer. The Prototype Model cannot be conclusively proven. Apart from contributing to second-language acquisition theo-ries on cross-linguistic tense-aspect morphology, this study can provide empirical evidence with significant pedagogical implications for the second-language learning classroom.

The author of this diploma thesis deals with the Proposal of a Risk Analysis Procedure in Technological Preparation for Foundry. Risk management is not currently applied in much detail at this present time. Analysis of the present risk management process in serial and prototype model tools will lead to the identification of risks within this discussion. It is then proposed for corrective actions for improvement of managing the current status to be presented and discussed. Target of this thesis is therefore the proposal of an updated risk analysis procedure in technological preparation for foundry.
