1. Road surface characterization using near infrared spectroscopy
University dissertation from Luleå : Luleå tekniska universitetAbstract : This thesis presents a technology and method for classifying and characterizing different road conditions such as dry asphalt and asphalt covered with water, ice and snow. The method uses light sources of different wavelengths to illuminate the road surface and a detector to measure the reflected light from the road surfaces, dependent on how the surface have absorbed, scattered and polarized the light it is possible to classify the road condition.

2. Vibration-based Assessment of Tensegrity Structures
University dissertation from KTH Royal Institute of TechnologyAbstract : Vibration structural health monitoring (VHM) uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life.The whole function, expressed by stiffness and frequencies of tensegrity structures are primarily related to the level of pre-stress.

3. Vibration Frequencies as Status Indicators for Tensegrity Structures
University dissertation from Stockholm : KTH Royal Institute of TechnologyAbstract : Applications of vibration structural health monitoring (VHM) techniques are increasing rapidly. This is because of the advances in sensors and instrumentation during the last decades. VHM uses the vibration properties to evaluate many civil structures during the design steps, building steps and service life. READ MORE

4. Computational model of abdominal aortic aneurysm inception and evolution
University dissertation from KTH Royal Institute of TechnologyAbstract : Incidence of abdominal aortic aneurysm (AAA) is increasing in the aging society of the western world. Development of AAA is mostly asymptomatic and is characterized by a bulge in the abdominal aorta. However, AAA may suddenly rupture, which results in an internal bleeding associated with a high mortality rate. READ MORE

5. Transitional and turbulent fibre suspension flows
University dissertation from KTH Royal Institute of TechnologyAbstract : In this thesis the orientation of macro-sized fibres in turbulent flows is studied, as well as the effect of nano-sized fibrils on hydrodynamic stability. The focus lies on enabling processes for new materials where cellulose is the main constituent. READ MORE
