2. 1. Fragmentation of Amino Acids and Microsolvated Peptides and Nucleotides using Electrospray Ionization Tandem Mass Spectrometry

   Author : Henrik Johansson; Henning Schmidt; Henrik Cederquist; Jens Jensen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atomic and molecular physics; Atom- och molekylfysik; fysik; Physics;

   Abstract : 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. READ MORE

4. 2. Urban Consolidation Centres : On Relationships between Customer Needs and Services in City Logistics

   Author : Henrik Johansson; Maria Björklund; Martina Berglund; Henrik Pålsson; Linköpings universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Abstract : 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. READ MORE

5. 3. Ionization and Fragmentation of Complex Molecules and Clusters : Biomolecules and Polycyclic Aromatic Hydrocarbons

   Author : Henrik A. B. Johansson; Henning Schmidt; Henrik Cederquist; Henning Zettergren; Thomas Schlathölter; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

   Abstract : 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. READ MORE

6. 4. Nonconformity Measures and Ensemble Strategies : An Analysis of Conformal Predictor Efficiency and Validity

   Author : Henrik Linusson; Ulf Johansson; Henrik Boström; Alexander Gammerman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Data Science; Machine Learning; Conformal Prediction; Classification; Regression; Computer and Systems Sciences; data- och systemvetenskap;

   Abstract : 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.

7. 5. Compensating for Unreliable Communication Links in Networked Control Systems

   Author : Erik Henriksson; Karl Henrik Johansson; Henrik Sandberg; Bruno Sinopoli; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; packet loss compensation; unreliable communication; control over wirless networks; Automatic control; Reglerteknik;

   Abstract : 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. READ MORE
