1. On the Characteristics of Fires in Tunnels
Sammanfattning : Important phenomena related to tunnel fires are presented including both experimental and theoretical work. The main focus is on the large-scale fire tests performed in 2003, in the Runehamar tunnel in Norway. LÄS MER
2. Catalytic Converters for Automotive Exhaust Applications. Flow Dynamics, Mass Transfer and Optimization
Sammanfattning : In order to reduce emissions from vehicles powered by an internal combustion engine, an exhaust aftertreatment system is normally mounted on the engine. This aftertreatment system normally consists of one or several catalytic converters. LÄS MER
3. Flow Pulsations in Fluid Power Machines - a Measurement and Simulation Study
Sammanfattning : Stricter requirements for better working environment involve noise and vibration control of hydraulic machines. The operational conditions for hydraulic machines, such as pressure and rotational speed, are also increasing and this makes it even more difficult to develop a quiet, vibration-free machine due to the interdependence between noise and escalating operational conditions.

4. Mitigation of Pressure Pulsations in Francis Turbine Draft Tube with a GuideVane System : A Numerical Investigation
Sammanfattning : The use of renewable energy such as water and wind to produce electricity has been proven extremely effective in Sweden. The ability of these renewable resources to produce clean output energy counters the adversities caused by non-renewable resources. LÄS MER
5. Pulse-Synchronous Intramuscular Pressure Oscillations
Sammanfattning : Background Intramuscular pressure (IMP) is measured in studies of tissue nutrition and in the diagnosis of compartment syndromes. Patients with compartment syndromes have an elevated IMP due to increased volume in a muscle compartment. LÄS MER
