1. Fragmentation of Amino Acids and Microsolvated Peptides and Nucleotides using Electrospray Ionization Tandem Mass Spectrometry
Sammanfattning : This thesis presents three different series of high energy (keV) collision experiments as well as a brief scientific introduction to the field. In the first series, protonated glycine and leucine were collided with carbon dioxide and a beam attenuation method was applied to determine their total fragmentation cross sections. LÄS MER
2. Urban Consolidation Centres : On Relationships between Customer Needs and Services in City Logistics
Sammanfattning : Urban Consolidation Centres (UCCs) are often conceived as an enabler to alleviate negative effects associated with distribution of goods in cities, such as traffic congestion and hazardous emissions. UCCs not only have the potential to reduce these effects but also provide alternative distribution solutions by introducing new transhipment points. LÄS MER
3. Ionization and Fragmentation of Complex Molecules and Clusters : Biomolecules and Polycyclic Aromatic Hydrocarbons
Sammanfattning : This work deals with ionization and fragmentation of biomolecules and polycyclic aromatic hydrocarbon (PAH) molecules. They are studied in the gas phase both as isolated molecules and as weakly bound clusters. LÄS MER
4. Nonconformity Measures and Ensemble Strategies : An Analysis of Conformal Predictor Efficiency and Validity
Sammanfattning : Conformal predictors are a family of predictive models that associate with each of their predictions a measure of confidence, enabling them to provide quantitative information about their own trustworthiness. In risk-laden machine learning applications, where bad predictions may lead to economic loss, personal injury, or worse, such inherent quality control appears highly beneficial, if not required.

5. Compensating for Unreliable Communication Links in Networked Control Systems
Sammanfattning : Control systems utilizing wireless sensor and actuator networks can be severely affectedby the properties of the communication links. Radio fading and interferencemay cause communication losses and outages in situations when the radio environmentis noisy and low transmission power is desirable. LÄS MER
