1. Absorbing boundary techniques for the time-dependent Schrödinger equation
Sammanfattning : Chemical dissociation processes are important in quantum dynamics. Such processes can be investigated theoretically and numerically through the time-dependent Schrödinger equation, which gives a quantum mechanical description of molecular dynamics.This thesis discusses the numerical simulation of chemical reactions involving dissociation.

2. Analys av statistik om spårväxlars underhållsbehov
Sammanfattning : Banverket har behov att det genomförs analyser till orsaker till funktionstörningar och förseningstid vid infrastrukturen. Spårväxlar är en av de anläggningar som har många funktionstörningar. Syftet med studien har varit att ta fram ett arbetssätt för att värdera enskilda spårväxlars funktionssäkerhet. LÄS MER
3. Development of life cycle cost model and analyses for railway switches and crossings
Sammanfattning : Infrastructure managers need to have a safe and available infrastructure, so that train operators can deliver a transport product at an affordable price. In the future, as traffic volume increases, higher utilisation of the existing capacity, less time for maintenance and fewer unplanned interruptions will be critical for meeting the ever increasing need of transport capacity.

4. Effects of some ward routines on behavioural and physiological adaptation to breast-feeding
Sammanfattning : The overall aim of this thesis was to study how early breast-feeding would be influenced by pethidine given during labour and by an emergency Caesarean section. Eighteen mother-infant pairs which were exposed and 26 which were not exposed to pethidine during labour were observed the first two hours after birth. LÄS MER
