Robots used in manufacturing today are tailored to their tasks by system integration based on expert knowledge concerning both production and machine control. For upcoming new generations of even more flexible robot solutions, in applications such as dexterous assembly, the robot setup and programming gets even more challenging. Reuse of solutions in terms of parameters, controls, process tuning,

After World War II the food sector in Sweden developed very quickly, following the example of the USA. The introduction of frozen food and self-service stores were rated as the major innovations since 1945, followed more recently by chilled products. For these products both packaging and an efficient supply chain are prerequisites. The innovations were supported by changes in society and by govern

Previous studies have shown that female ECAs are more likely to be abused than male agents, which may cement gender stereotypes. In the study reported in this paper a visually androgynous ECA in the form of a teachable agent in an educational math game was compared with a female and male agent. The re-sults confirm that female agents are more prone to be verbally abused than male agents, but also

This paper reports on an inquiry into the use of metadata, publishing formats, and markup in editor-managed open access journals. It builds on findings from a study of the document architectures of open access journals, conducted through a survey of 265 journal web sites and a qualitative, descriptive analysis of 4 journal web sites. The journals’ choices of publishing formats and the consistency

Out-of-body experiences (OBEs) are characterized by disruptions between normally integrated subsystems that modulate the visuo-spatial representation of embodied consciousness. Similar disruptions in the coordination of cognitive processes, and corresponding alterations in cortical functional connectivity, have been observed in highly suggestible individuals following a hypnotic induction and afte

In this study, we will show that children, in their 2L1 acquisition, begin with the adverbs from the lower part of the hierarchy, and start using their higher level adverbs clearly later on, which seems to support a Structure Building Model. Inversely, we will show that adult L2 learners, even from the very earliest stages of acquisition, use the adverbs from the highest levels, which indicates th

Concepts of cognitive radio are yet in an early stage of development. They aim at improving the efficiency of spectrum utilization by exploiting locally and temporally vacant parts of the spectrum. When hierarchical spectrum access is considered, secondary users are authorized to use spectrum white spaces on a non-interfering basis, where minimal impact on the primary systems has to be ensured.

Popular Abstract in Swedish Råttans urinblåsa har studerats ur olika aspekter, sedan antingen ett standardiserat avflödeshinder åstadkommits eller hälften av urinblåsans nervförsörjning avlägsnats. Avflödeshindret har åstadkommits genom att en silkestråd knutits runtom urinröret så att det försnävats. Genom att en knappt mm-vid metallstav knutits om samtidigt och sedan avlägsnats, har graden av avMedian micturition volume decreased early after partial outlet obstruction, 24 hrs total obstruction and hemidenervation. Degeneration release of transmitter may explain this, assuming that bladder wall distension causes nerve degeneration. Micturition pressure decreased simultaneously in the partially denervated and 24 hrs obstructed groups, probably due to the reduced number of functionally inta

Popular Abstract in Swedish Allt levande består till stor del av proteiner. De bygger upp muskler och hår, transporterar syre i blodet och ser till att kemin i kroppen fungerar som den ska. Men hur tillverkas då dessa proteiner? Jo i alla celler finns ribosomer, proteinfabriker. En bakterieribosom är ungefär 0.02 mikrometer stor. Den är sammansatt av proteiner och RNA-kedjor. RNA utgör den funktioTranslation is a central biological process, that is catalysed by a machinery consisting of RNA and protein. In this thesis three different protein components of the bacterial protein synthesis system have been structurally studied. Ribosome recycling factor (RRF) is essential for the recycling step of the translation cycle, elongation factor SelB is a specialised elongation factor needed for co-t
