1. Development and Implementation of a Mouldable Soft Magnetic Composite
Sammanfattning : Electrical machines, chokes and induction heaters are found in most homes,offices and factories all over the world. They are used to create movement, filtrate the power or to generate heat. A typical unit consist of a coil and a flux conductor material. LÄS MER
2. Structure-Performance Relations of Oxygen Barriers for Food Packaging
Sammanfattning : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. LÄS MER
3. Process Modeling of Composite Manufacturing
Sammanfattning : The focus of this research thesis is toward developing a framework for holistic modeling of composites manufacturing of fiber reinforced structural composites. The processes that have been considered are Liquid Composite Molding (LCM) and Out Of Autoclave (OOA) processes, ranging from Liquid Resin Infusion (LRI) and Resin Transfer Molding (RTM) in LCM processes, to Vacuum Bag Only (VBO) and Evac prepregs in OOA processes.

4. Novel RF MEMS Devices Enabled by Three-Dimensional Micromachining
Sammanfattning : This thesis presents novel radio frequency microelectromechanical (RF MEMS) circuits based on the three-dimensional (3-D) micromachined coplanar transmission lines whose geometry is re-configured by integrated microelectromechanical actuators. Two types of novel RF MEMS devices are proposed. LÄS MER
5. Environmentally friendly plasticized PVC by means of nanotechnology
Sammanfattning : Polyvinyl chloride (PVC) is used in a wide range of industrial areas. Manufacturing of PVC products requires use of additives, such as plasticizers, heat stabilizers and flame retardants. LÄS MER
