Popular Abstract in Swedish Jorden är ett ytterst komplext och dynamiskt system. Livet har format planeten och utvecklats i takt med förändrade livsvillkor. Ekosystemen kontrolleras i hög grad av klimatet. Snabbt förändrade villkor innebär betydande påfrestningar för åtskilliga arter och ekosystem, inklusive planetens mest dominerande art, människan. Avhandlingens huvudfokus är att undersöka samsThe Earth is a highly complex and dynamic system. Life has shaped the entire planet and evolved in response to living conditions. Ecosystems are heavily affected by climate. Rapidly changing conditions imply considerable stress on several species and ecosystems, as well as to the most dominant species on the planet. The main focus of this thesis is to investigate climate and anthropogenic interac

Continuum based elasto-plastic models for paperboard have been established in the work herein. The thesis begins with an introductory section that describes some of the background of the problem and gives some more motivation for the modeling choices made in the appended papers. Some preliminary simulation results on the folding operation is also provided. The main part of the thesis consists of t

This textbook is a 4th year(Sweden)/5th year (USA) text in digital communication theory and practice. Chapters include baseband pulse transmission, carrier transmission, synchronization, channels, coding and information theory, and advanced topics. Each chapter ends with 25 home exercises. Worked examples and Matlab tools are integrated with the text.

Excited states in 59Zn were observed for the first time following the fusion-evaporation reaction 24Mg + 40Ca at a beam energy of 60 MeV. The GASP array in conjunction with the ISIS Silicon ball and the NeutronRing allowed for the detection of n-rays in coincidence with evaporated light particles. The mirror symmetry of 59Zn and 59Cu is discussed.

In order to increase the knowledge on human behavior in smoke, an evacuation experiment was performed in a road tunnel in Stockholm in July, 2014. The experiment included 66 participants, who individually were instructed to evacuate a smoke-filled tunnel. The experiment focused on measuring the participants’ walking speed in smoke-filled, as well as smoke-free parts of the tunnel. In addition, exi

THE POINT has its point of departure in the indivisible point of mathematics. In Swedenborg's Principia rerum naturalium (1734) the mathematical points are given an ontological significance. The world appears when God, like an artist drawing with his pencil, gives motion to the point. The world consists of circulating points. With spider metaphors Swedenborg postulated that the world is built on m
