Combining parallel search and parallel consistency in constraint programming

Program parallelization becomes increasingly important when new multi-core architectures provide ways to improve performance. One of the greatest challenges of this development lies in programming parallel applications. Declarative languages, such as constraint programming, can make the transition to parallelism easier by hiding the parallelization details in a framework. Automatic parallelizatio

Modeling of a Boiler Pipe with Two-Phase Flow Instabilities

Tubes with boiling are common elements of many processes. They appear in steam generators and refrigerators and many other systems. The behavior of such systems is complicated and many physical phenomena are involved. It has for example been observed that different types of instabilities can occur. In this paper we will discuss modeling of tubes with boiling. As an application we will discuss an i

Absorption and scattering of light from ensembles of randomly oriented aggregates

Ensembles of aggregates are important in the areas of aerosols and combustion physics. This paper presents one approach to the absorption and scattering of light from aggregates where the individual primary particles are small compared to the wavelength, whereas the aggregate can be large compared to the wavelength. The method is related to the Rayleigh-Debye-Gans (RDG) theory. The difference is t

Investigation of the Hyperfine Structure of Te 125 in the 5p^(3)6s^(5)S_(2) Level of the Te I Spectrum by Optical Double Resonance and Level Crossing Spectroscopy

Using an enriched sample in a high temperature scattering cell we have determined the hyperfine structure of Te 125 in the 5 p 3 6 s 5 S 2 level of the Te I spectrum by the optical double resonance and level crossing techniques. For the magnetic dipole interaction constant a we obtain | a (5 p 3 6 s 5 S 2 Te 125 )| = 1 010.4 (1.3) MHz The spin density at the nucleus, calculated using this value, i

Riskbaserad utvärdering av alternativ brandskyddsutformning av byggnader

In this report a riskbased method is used to verify the fire protection in a fictitious building. The purpose of the report is to evaluate if it is possible to use a riskbased method when performing the construction of the fire protection in a building. The riskbased method is used to calculate the risk, with respect to the occupants, associated with an accepted fire protection solution according

Analyzing Material Properties for Efficient Processing of Spruce to Ethanol

Fuel production from renewable resources will likely be a prerequisite for reducing the negative anthropogenic impact on the environment and, at the same time, ensuring future energy security. In this thesis, the conversion of typical Swedish biomass, mainly Norway spruce, to ethanol was studied. The first part of the work focused on the degradation of biomass to fermentable sugars.
