1. A space-time shape for easier spatiotemporal visualization in traffic networks
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknikSammanfattning : Modern big data systems are enabling new possibilities that never were thought possible in the past. The ability to gather massive data on an individual level has made fields like space-time geography bloom in the latest decennia. The usage of shapes in a 3D space allows us to visualize certain phenomena over time. LÄS MER
2. A novel approach for functionalising and separating Tröger's Base Analogues
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Tröger’s Base (TB) is a bicyclic compound containing a methanodiazocine group between two aromatic rings. The methylene bridge forces the molecule to have a bent formation; thus, the aromatic rings are close to 90 degrees relative to each other, resulting in a rigid concave aromatic cavity. LÄS MER

5. Competition & R&D Subsidies: New Perspectives on the Public-Private Nexus
C-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomiSammanfattning : Using a dynamic panel model, this paper empirically examines the effect of public R&D subsides on privately funded R&D in a new light. By synthesizing the theories on public R&D support with those on the relationship between R&D and market structure, we explore to what extent R&D expenditures may depend on public funding in a non-linear, concave fashion with respect to product market competition.
