Permanent deformation properties of asphalt concrete mixtures
(Dr. ingeniøravhandling, 0809-103X; 2002:78, Doctoral thesis, 2002)
Rutting is recognized to be the major distress mechanism in flexible pavements as a result of increase in tire pressures and axle loads. Rutting is caused by the accumulation of permanent deformation in all or some of the ...
Wind flow studies for drifting snow on roads /
(Dr. ingeniøravhandling, 0809-103X; 2002:82, Doctoral thesis, 2002)
During strong winds, drifting snow causes problems on roads in many harsh winter climate countries. Increased snow-removal costs, reduced access and safety problems are typical results of excessive snowdrift sedimentation ...
No fire without smoke : prediction models for heat release and smoke production in the SBI test and the Room Corner test based on Cone Calorimeter test results
(Doktoravhandlinger ved NTNU, 1503-8181; 46, Doctoral thesis, 2002)
Smoke production in fire represents a threat because fire smoke reduces visibility and because fire smoke is toxic. One way to reduce the risk of persons being overcome by smoke during evacuation is by setting requirements ...
Shock Tube Experiments on Nitromethane and Promotion of Chemical Reactions by Non-Thermal Plasma
(Dr. ingeniøravhandling, 0809-103X; 2002:67, Doctoral thesis, 2002)
This dissertation was undertaken to study two different subjects both related to molecular decomposition by applying a shock tube and non-thermal plasma to decompose selected hydrocarbons. The first approach to molecular ...
Molecular Effects on Evaporation and Condensation
(Dr. ingeniøravhandling, 0809-103X; 2002:123, Doctoral thesis, 2002)
In this thesis the evaporation from and condensation on a plane liquid surface have been studied by analysis and molecular dynamics simulations. The effect of the condensation coefficient on the inverted temperature gradient ...
Flow vaporization of CO2 in Microchannel Tubes
(KKT-rapport, 1503-0342; 2002:1, Doctoral thesis, 2002)
Real-time reconfigurable devices implemented in UV-light programmable floating-gate CMOS
(Dr. ingeniøravhandling, 0809-103X; 2002:52, Doctoral thesis, 2002)
This dissertation describes using theory, computer simulations and laboratory measurements a new class of real time reconfigurable UV-programmable floating-gate circuits operating with current levels typically in the pA ...
Freeze-Thaw Resistance of Concrete: Effect of: Curing Conditions, Moisture Exchange and Materials
(Dr. ingeniøravhandling, 0809-103X; 2001:4, Doctoral thesis, 2001)
Research on freeze-thaw resistance of concrete in general and on curing and moisture conditions in particular is motivated from an economic and product sustainability point of view. Specifically, it is argued for the ...
Fatigue Life Prediction of an Aluminium Alloy Automotive Component Using Finite Element Analysis of Surface Topography
(Doctoral Theses at NTNU, 1503-8181; 2006:25, Doctoral thesis, 2006)
A 6082 aluminium alloy has been characterized with regard to the influence of surface roughness on fatigue strength. Fatigue life testing of smooth specimens was used to establish reference curves for the material in ...
Computer Simulation of Residual Stress and Distortion of Thick Plates in Multielectrode Submerged Arc Welding: Their Mitigation Techniques
(Dr. ingeniøravhandling, 0809-103X; 2001:75, Doctoral thesis, 2001)
Welding is the main joining method used in shipbuilding. A multi-electrode submerged arc welding is usually applied to long joints of massive components since the early 1950s. The problem of welding stresses and deformations ...
