1. Water-Metal Surfaces : Insights from core-level spectroscopy and density functional theory
Sammanfattning : Computational methods are combined with synchrotron-based techniques to analyze the structure and bonding of water and water plus hydroxyl at metal surfaces under UHV and at near-ambient conditions. Water-metal interaction plays a crucial role in a multitude of cosmic, atmospheric and biological phenomena as well as heterogeneous catalysis, electrochemistry and corrosion. LÄS MER
2. Geometry and Critical Configurations of Multiple Views
Sammanfattning : This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. LÄS MER
3. Searing apparent surfaces : infernal females in four early works of William Blake
Sammanfattning : This study explores the quality of the infernal as a specifically female expression of desire in William Blake's work. The contention is that the infernal constitutes an essential female element of the divine in Blake's early work but is demonized in the late work as an attribute of the Female Will. LÄS MER
4. Dynamiskt belastade tribologiska system under plastisk formning, del II --- analyserade genom akustisk emission
Sammanfattning : The dynamic friction process and contact surface between tool and working material in a plastic forming process is hard to describe in mathematical form and hard to monitor and control in real time. High production speed and highly optimised forming operations result in great demands on the control equipment. LÄS MER
5. Rough surfaces in contact : artificial intelligence and boundary lubrication
Sammanfattning : Interacting surfaces are found in mechanical systems and components. Since engineered surfaces are not perfectly smooth, only a fraction of the nominal surface area is actually in contact. This fraction is denoted as the real area of contact, Ar, and is formed by the sum of the contact spots between the two touching surfaces. LÄS MER
