1. Genetic variability commonly affecting neurodegeneration and neuroinflammation
Sammanfattning : Loss of nerve cells and axons is a common feature of common complex neurodegenerative disorders, such as Alzheimer’s and Parkinson’s diseases. However, also Multiple Sclerosis (MS), primarily an autoimmune disorder, has a prominent neurodegenerative component. LÄS MER
2. Applying lean principles and set-based approaches in product development
Sammanfattning : The research described in this thesis addresses the problem of transformation to lean product development (LPD) and how to introduce and support the use of set-based design (SBD) in the concept development process. The original description of SBD does not define how to generate, evaluate and reduce a set of design solutions. LÄS MER
3. Improving engineering change processes by using lean principles
Sammanfattning : The purpose of this research was to test the usefulness of the 13 lean principles for product development by Morgan & Liker when improving an engineering change (EC) process. The EC-process was studied at four firms. The firms were active in three different industrial branches. Two of the firms are situated in Sweden and two in Finland. LÄS MER
4. On the Agglomeration of Particles in Exhaust Gases
Sammanfattning : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. LÄS MER
5. Electron Tunneling and Field-Effect Devices in mm-Wave Circuits
Sammanfattning : Short high-frequency electromagnetic pulses, also referred to as wavelets, are considered for use in various short-range impulse based ultra-wideband applications, such as communication, imaging, radar, spectroscopy, and localization. This thesis investigates field-effect and tunneling based semiconductor devices and their operation in millimeter-wave (mm-wave) impulse transceivers. LÄS MER
