1. Snow contamination of cars: Collisions of ice particles with surfaces
Sammanfattning : Seasonal snow cover on roads causes car accidents that lead to human suffering and economic loss. Snow cover decreases visibility and road-tire friction. Advanced active safety systems have been developed to cope with sudden changes in driving conditions and have been engineered to act as quickly as possible. LÄS MER
2. Ice accretion and ice adhesion to polymer material
Sammanfattning : .... LÄS MER
3. Toward Anti-icing and De-icing Surfaces : Effects of Surface Topography and Temperature
Sammanfattning : Icing severely affects society, especially in the Nordic countries. Iceaccumulation can result in critical performance problems and safetyconcerns for instance in road, air and sea transportation, transmissionlines, marine and offshore structures, wind turbines and heat exchangers.

4. Freezing Temperature Flows in Railway Tunnels and its Consequence on the Rock Supporting Structure, the Rock and the Reinforcing Elements
Sammanfattning : Water in the surrounding rock mass flows into the tunnel via naturally occurring joints and via cracks caused by the blasting used to excavate the tunnel. The most common method in Sweden to reduce or prevent leakage problems are first and foremost the use of grouting. LÄS MER
5. Snow Contamination of Cars: Adhesive Particle Collisions with Exterior Surfaces
Sammanfattning : An ongoing challenge regarding autonomous vehicles is the obstruction of sensors by contaminants on exterior surfaces. This often occurs when driving in harsh weather conditions, where the contaminant can be, for example, water spray, dirt, or snow. LÄS MER
