Swedish emigration to America is a topic that does not hold a major position in Swedish historical research anymore. At one time, during the 1960s and 1970s, there were a major research project, Sweden and America after 1860, that focused primarily on the reasons of the migration, the demographics of the migration and to some extent what happened to the emigrants in America. The research project d
Based on recent advances in control theory, we propose the notion of jitter margin for periodic control tasks. The jitter margin isdefined as a function of the amount of constant delay in the controlloop, and it describes how much additional time-varying delay can betolerated before the loop goes unstable. Combined with schedulingtheory, the jitter margin can be used to guarantee the stability and

In relativistic heavy ion physics, nuclei are collided at large center-of-mass energies and the dynamics of the collision is probed by measuring the produced particles. In the collisions the baryon number of the initial nuclei is conserved. By measuring the baryon rapidity densities and subtracting the anti-baryon rapidity densities it is possible to study the stopping of the participating nucleon
This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. This allows the fabrication of thre
Empirical and theoretical literature on elections in authoritarian regimes has illustrated the importance of oppositional cohesion. It has been argued that these elections are more likely to result in positive democratic effects as well as oppositional victory if the opposition has formed a unified pre-electoral coalition. Still, our knowledge is limited when it comes to explaining why and when
