1. Konceptstudie kring snabb-fästen för skärutrustning till en motorsåg
M1-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och designSammanfattning : This report describes a thesis project together with Husqvarna Group at the Advanced Development Handheld department. The aim of the project was to develop a prototype for a more efficient rapid bar exchange for one of Husqvarnas chainsaws. The reason for this is that the current design for changing the bar and chain is time consuming. LÄS MER
2. Are large clearcuts the only way to manage forests? : a study of economic performance and deadwood production of various silviculture systems
Master-uppsats, SLU/Southern Swedish Forest Research CentreSammanfattning : Our forests are a natural resource which is needed for many purposes. Their importance and different values are expressed in the Swedish legislation, where production and environmental goals are set as equal. To many it is not sufficient, there has been a debate regarding how forests are managed and the practice of clear-cutting for decades. LÄS MER

5. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER
