1. Structure of Zero Pressure Gradient High Reynolds Number Turbulent Boundary Layers
Sammanfattning : This thesis presents part of the large research program funded by the European Commission calledWallturb: A European synergy for the assessment of wall turbulence. The main aim of this researchprogram is to create new experimental and numerical databases on the characteristics of turbulent wall-bounded flows, especially turbulent boundary layers. LÄS MER
2. The Statistics of Emission and Detection of Neutrons and Photons
Sammanfattning : One particular purpose of nuclear safeguards, in addition toaccounting for known materials, is the detection, identifying and quantifying unknown material, to prevent accidental and clandestine transports and uses of nuclear materials. This can be achieved in a non-destructive way through the various physical and statistical properties of particle emission and detection from such materials. LÄS MER
3. The Diversity and Unity of Reactor Noise Theory
Sammanfattning : The study of reactor noise theory concerns questions about cause and effect relationships, and the utilisation of random noise in nuclear reactor systems. The diversity of reactor noise theory arises from the variety of noise sources, the various mathematical treatments applied and the various practical purposes. LÄS MER
4. Safeguards: Modelling of the Detection and Characterization of Nuclear Materials
Sammanfattning : Nuclear safeguards is a collective term for the tools and methods needed to ensure nonproliferation and safety in connection to utilization of nuclear materials. It encompasses a variety of concepts from legislation to measurement equipment. LÄS MER
5. Azimuthal Correlations in Dijet Events from Deep Inelastic Positron-Proton Scattering at HERA
Sammanfattning : Correlations in the azimuthal angle between dijets produced in deep inelastic $e^{+}p$ scattering events, collected by the H1 experiment during 1999-2000, have been investigated. Cross sections are presented as a function of the azimuthal separation between the two jets in the hadronic center of mass frame, $Deltaphi^{*}$, in different regions of the photon virtuality $Q^{2}$ and in different regions of the Bjorken scaling variable $x_{Bj}$.
