Fuel cells are electrochemical devices that transform chemical energy into electricity. Solid oxide fuel cells (SOFCs) are particularly interesting because they can handle the reforming of hydrocarbon fuels directly within the cell. This is possible due to their high operating temperature. The purpose of this study is to develop an anode-supported SOFC model, to enhance the understanding of the in

The densification of mobile networks in order to meet increased capacity demands is ongoing, needed and costly. A few papers have been published based on the insight that the fixed broadband networks offer a multitude of sites, for instance our homes, for potential small cell deployment providing backhaul capacity and power without site costs. However, in order to reach economical large-scale bene

Texten tar upp gränsmotivet i jugoslavisk film, framför allt genom att lyfta fram två filmer, Innan regnet faller (Pred Dozhdot, Mancevski, 1994) och Ingenmansland (Nicija zemlja, Tanovic, 2001). Dessutom diskuteras begrepp som jugoslavisk och postjugoslavisk film.

Abstract in UndeterminedWe investigated age-related changes in the semantic distance between successively generated words in two letter fluency tasks differing with respect to demands placed on executive control. The semantic distance was measured by Latent Semantic Analysis (LSA). The results show that older people have a larger semantic distance between successively generated items than young pe

Popular Abstract in English It is hard to imagine present day’s lifestyle without the use of modern technologies as prevalent in sectors including bioscience & technology and the semiconductor & chemical industries. In technological advances of biosensors, catalysis, and microelectronics, the surface modification of materials (which includes modification of the wetting, structural, electriThe research work described in this thesis is concerned with the modification of oxide surfaces, as reflected by its title. The surfaces and their modification have been studied using a range of experimental surface characterization tools, in particular x-ray photoelectron spectroscopy (XPS), fluorescence microscopy, scanning electron microscopy, atomic force microscopy, and scanning tunneling mic

In this paper, we propose a method for selfcalibration of a robotic manipulator force observer, which fuses information from force sensors and accelerometers in order to estimate the contact force exerted by a manipulator to its environment, by means of active motion. In robotic operation, during contact transition accelerometers and force sensors play a very important role and serve to overcome m
