1. Performing Punk : Subcultural Authentications and the Positioning of the Mainstream
Sammanfattning : This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic.

2. Control of weldability : Research leading to the development of two new quenched and tempered tool steels
Sammanfattning : The understanding of the hardenability is important in steel development with respect to weldability of steels as well as to the design of quenched and tempered steels.The common way to judge if steel is suitability to welding is the use of a carbon equivalent, which reflects the alloy content to the hardenability of the heat affected zone (HAZ).

3. Impact wave process modeling and optimization in high energy rate explosive welding
Sammanfattning : Impact waves are used in many different industries and are classified according to whether they cause plastic or elastic deformations. In the plastic deformation mode, these waves can be used to produce special electrical joints. In the elastic deformation mode, they can be used to detect leakage or to measure the thickness of pipes. LÄS MER
