1. Thermally cured coil-coatings utilizing novel resins and fatty acid methyl esters as reactive diluents
Sammanfattning : Solvent-borne thermally cured coil-coating resins contain large amounts of volatile organic solvents in order to obtain suitable flow for film application. This work describes how the expensive and environmental hazardous volatile organic solvent content of a solvent-borne thermally cured polyester/melamine coil-coating system can be reduced by introduction of fatty acid methyl esters (FAMEs) as reactive diluents and modification of the polyester binder resin.

2. Multivariable Adaptive Control
Sammanfattning : This thesis treats the problem of direct adaptive control of linear multivariable systems. The parametrization problem of adaptive control is discussed extensively. A pole-placement problem and a model-matching problem are formulated and interpreted in terms of model reference control. LÄS MER

4. Multiple-Bit Errors in Computer Systems
Sammanfattning : This thesis discusses the types of transient faults caused by heavy-ion or a-particle radiation that manifest as multiple-bit errors and how information redundancy techniques can achieve fault tolerance with respect to some classes of multiple-bit errors. The first part of the thesis considers the fault modelling problem, beginning with the problem of how single event upsets (SEUs) originating from faults in register cells in microprocessors manifest as primary errors.

5. Stereo and regio controlled halogenation, and synthesis of low molecular weight carbohydrates
Sammanfattning : The regio- and stereoselective introduction of halogens as well as unsaturation into carbohydrates is investigated with triphenylphosphine - halide systems. Three different glycosidation methods are presented. LÄS MER
