The generalized bimodal traffic stream model and two regime flow theory

A new generalized bimodal traffic stream model deriving theoretically (i.e., via some underlying model of driver behavior) from (local) equilibrium solutions of a kinetic equation of vehicular traffic is presented and shown to have the correct flow behavior at jam density. This bimodal traffic stream model depends not only on parameters such as the desired speed w, the headway σ(0) at jam density

15 nedslag i klimatforskningen : dåtid, nutid, framtid

Från humlor, metanbomber och luftpartiklar till markkonflikter och klimatanpassning på medborgarnivå. Klimatförändringen och dess konsekvenser blir alltmer tydlig och sträcker sig allt längre in i samhällsfrågorna och vardagslivet. Klimatfrågan handlar dels om naturvetenskapliga frågeställningar, om atmosfärsprocesser och förändringar i havet och på tundran, och om naturresurser och tjänster som v

Some Aspects of Wear and Structural Dynamics

The topic of this thesis is dynamics and wear of structures. In the six appended papers different aspects of wear and dynamics of a model system are studied. The considered system consists of a long slender rod with unilateral supports, subject to harmonic and stochastic excitation. The rod is held at one end with stiff springs preventing translation and rotation and constrained by loose sup

Small-Molecule Galectin Inhibitors - On Tweezers and Talosides

Abstract Work on the design, synthesis, and biological evaluation of galectin inhibitors is presented. The most significant results relate to the development of galactose-based arginine “tweezers” and taloside-based galectin inhibitors. The galectins are a β-galactoside binding protein family. They are involved in cancer and inflammation, thus comprising interesting pharmaceutical targets. Galact

Glass, alcohol and power in Roman Iron Age Scotland

Roman glass from indigenous sites is a key source material for studying the impact of Rome on Iron Age Scotland, but it has never been properly studied. This work fills that gap. This study is based on the Roman glass vessels found on non-Roman/native sites north of Hadrian’s Wall, dated mainly to the Roman Iron Age (AD 10-400 AD). These often-overlooked broken sherds of glass are shown to be pa

Altering the Point of You : Perspectives on Intersubjectivity and Metacognition

Popular Abstract in Swedish Syftet med denna avhandling var att undersöka olika aspekter på intersubjektivitet, metakognitiv utveckling och mellanmänsklig förståelse. Mer precist var syftet att undersöka hur några specifika teorier – mentaliseringsteorin, teorin om primär intersubjektivitet, samt interaktionsteorin – beskriver vilken roll intersubjektivitet har att spela i denna utveckling. De förThe aim of the thesis was to examine different aspects of the role of intersubjectivity in metacognitive development and in social understanding. More specifically, it investigates how different theoretical frameworks, such as mentalization theory, the theory of primary intersubjectivity, and interaction theory describe the developmental role of intersubjectivity. The suggestions these theories ma

Markups and Export Pricing

We analyze empirically product-price variation across export destinations using detailed firm-product data. Most recent studies using highly disaggregated data emphasize variations in product quality as an explanation as to why firms charge different prices for the same product on different export markets. In this paper, we take an alternative approach and assume that variations in firms' export p

New Codes on Graphs Constructed by Connecting Spatially Coupled Chains

A novel code construction based on spatially coupled low-density parity-check (SC-LDPC) code chains is presented. The proposed code ensembles are described by graphs in which individual SC-LDPC code chains of various lengths serve as edges. We demonstrate that connecting several appropriately chosen SC-LDPC code chains results in improved iterative decoding thresholds compared to those of a single
