1. Introducing New Materials in the Automotive Industry : Managing the Complexity of Introducing New Materials in Existing Production Systems
Sammanfattning : Passenger vehicles are central to Western society, and contribute to a significant part of our greenhouse gas emissions. In order to reduce emissions, the automotive industry as a whole is working to reduce mass in passenger vehicles in order to reduce energy consumption. LÄS MER
2. On Material selection and its consequences in product development
Sammanfattning : Technological development, and increased demands on sustainable solutions, have impacted the development of new products. New products need to be more efficient, and there are increased possibilities for a more diversified and informed decision regarding what materials are used in the product. LÄS MER
3. Nanosecond tandem optical parametric oscillators for mid-infrared generation
Sammanfattning : This thesis discusses a new scheme for generating radiation in the mid infrared spectral region, especially the 3.5-5 µm range. The scheme uses established Nd3+-lasers at 1.06 µm and down conversion in nonlinear optical crystals. LÄS MER
4. Tandem optical parametric oscillators using volume Bragg grating spectral control
Sammanfattning : This thesis describes research on near degenerate quasi phase-matched opticalparametric oscillators (OPO) where volume Bragg gratings (VBG) are used toproduce narrow oscillation bandwidth. These OPOs are then used to pump a secondOPO to generate mid-infrared radiation. The atmospheric transmission windows in the 3. LÄS MER
5. Towards a sustainable mobility paradigm? An assessment of three policy measures
Sammanfattning : Transportation and mobility are important components in the organisation and structure of people´s daily activities, but the transport sector has considerable environmental impacts, e.g. greenhouse gas emissions and land use. LÄS MER
