6. System Simulation of Partially Premixed Combustion in Heavy-Duty Engines : Gas Exchange, Fuels and In-cylinder Analysis
Sammanfattning : The concept of partially premixed combustion (PPC), applied to conventional diesel engines, has shown to yield high gross efficiencies and low emissions of oxides of nitrogen and soot. PPC emerged from the knowledge gained from homogeneous charge compression ignition (HCCI) research. LÄS MER
7. Compaction, Flow and Dispersion in a Chromatographic Column
Sammanfattning : An experimental and theoretical study of compaction, flow and hydrodynamic dispersion in a chromatographic column containing non-rigid particles is presented. Experiments were performed using chromatographic columns packed with either a dextran-based chromatographic gel or glass beads. LÄS MER
8. Influence of inhomogeneities on the tensile and compressive mechanical properties of paperboard
Sammanfattning : The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. LÄS MER
9. Truncated Signed Distance Fields Applied To Robotics
Sammanfattning : This thesis is concerned with topics related to dense mapping of large scale three-dimensional spaces. In particular, the motivating scenario of this work is one in which a mobile robot with limited computational resources explores an unknown environment using a depth-camera. LÄS MER
10. Thermoset polymers and coatings subjected to high compressive loads
Sammanfattning : This study describes the mechanical response of thermoset polymers under high compressive loads. The study is divided into two parts. The first part focuses on the behaviour of a powder coating when used in a clamping force joint and how the properties vary when the chemical and physical structure of the coating is changed. LÄS MER
