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

We present fully self-consistent results for the self-energy of the electron gas within the GW approximation. This means that the self-consistent Green’s function G, as obtained from Dyson’s equation, is used not only for obtaining the self-energy but also for constructing the screened interaction W within the random-phase approximation. Such a theory is particle and energy conserving in the sense

The paper describes a novel method for self tuning cylinder pressure based heat release computation that is suitable for online usage in e.g. combustion phasing control applications. The method estimates the polytropic exponents and cylinder pressure offsets immediately preceding and succeeding the combustion event respectively using a fast nonlinear least squares method. The polytropic exponent a
