Coping with complexity. Sociocybernetics as a Framework for Communication Management.
This paper presents a generic hardware-MAC for systems designed based on high rate (IEEE 802.15.3) and low rate (IEEE 802.15.4)Wireless Personal Area Networks. functionality that are better run in hardware are moved over from the software part of the MAC layer. An easy to access memory like interface has been defined for data and control transfer between the software and hardware parts of theMAC l
The aim of this report is to describe the concept of Double Skin Façades based on different sources of literature. Although the concept is not new, there is a growing tendency from the architects to put it into practice. Its complexity and adaptability to different climatic conditions increase the need for careful design. Since the construction types can differ from one location to another, it is
Fuel production from renewable resources will likely be a prerequisite for reducing the negative anthropogenic impact on the environment and, at the same time, ensuring future energy security. In this thesis, the conversion of typical Swedish biomass, mainly Norway spruce, to ethanol was studied. The first part of the work focused on the degradation of biomass to fermentable sugars. More specifica
Saccharomyces cerevisiae ferments hexoses in lignocellulosic hydrolysates under anaerobic conditions with high rates and ethanol yields. However, S. cerevisiae is naturally unable to utilize the pentose fraction of the hydrolysates. Xylose is the most abundant pentose sugar, and although recombinant S. cerevisiae strains capable of ethanolic xylose fermentation have been obtained through metabolic
