The demand for improved models for simulation of mechanical problem is today very great, especially since today's computer capacity makes it possible to simulate large and complicated problems. In some applications, temperature effects and the heat generated from inelastic deformation can not be neglected in order to achieve a good accuracy of the simulation. In this thesis, a model for simulatio
Historik över fäktmästarinstitutionen vid Lunds universitet, dess lokaler och andra yttre förutsättningar samt kortbiografier över samtliga ämbetets innehavare.
The scientific study of mysticism includes at least the following dimensions: the mystical experience, its consequences in the life of the mystic, ritual behavior, and intellectual and traditional aspects. The author distinguishes between two types of mystical experience: the cataphatic type and the apophatic type, also know as via affirmativa and the via negativa. The study is psychological in th
Popular Abstract in Swedish Människan har märkbart ändrat Jordens ekosystem och dess funktioner. Genom avskogning och konvertering av naturliga ekosystem till åkrar och betesmarker så har människor skapat helt nya typer av ekosystem. Cirka en tredjedel av den koldioxid (CO2) som människor har släppt ut i atmosfären, kommer från dessa aktiviteter, resten beror till största delen på utsläpp från förThrough deforestation and conversion of natural ecosystems to croplands and pastures, have humans released vast amounts of carbon (C) dioxide (CO2) into the atmosphere. Roughly one third of the cumulative anthropogenic emissions until today stem from these practices, the remainder being mostly due to fossil fuel combustion. The extra CO2 has caused an increase in global air temperature, and both t
In this paper, the results from a joint industry-academia project in industrial robotic force control are presented. The extension and implementation of an external sensor system for an industrial robot system, which can be used for high-bandwidth force control, are described. Results from two industrial applications using the system are presented, a stub grinding application using a new compliant
Mit einer Thermopuppe wurde die Erwärmung durch langwellige Wärmestrahlung beim Tragen von Schutzkleidung erfasst, wobei Material und Anzahl der Schichten der Unterbekleidung variiert wurden. Die Unterbekleidung minderte die durch Strahlungs-Absorption hervorgerufene Erwärmung. Die dabei beobachtete hohe negative Korrelation mit der thermischen Isolation zeigt Möglichkeiten zur Berücksichtigung vo
A sequential Bayesian estimation algorithm for joint positioning and multipath mitigation in global navigation satellite systems is presented, with an underlying process model that is especially designed for dynamic user scenarios and dynamic channel conditions. In order to facilitate efficient integration into receivers it builds upon complexity reduction concepts that previously have been applie
