Supportive legislation and improving technologies are making bioenergy an increasingly attractive energy source for Europe both economically and environmentally. However, abundant resources remain untapped across many member states in the European Union (EU). The Bioenergy Network of Excellence (NoE) entitled Overcoming Barriers to Bioenergy in Europe is charged with the task to identify critical
Cationic polymers in the form of anion-exchange membranes (AEMs) may enable a route towards low platinum or even platinum-free alkaline membrane fuel cells with the potential to oxidize more complex fuels than hydrogen and methanol [1-4]. The main challenges for the AEMs are currently to enhance the alkaline stability of the cationic group and to improve the ion conductivity. In this context, ther
Popular Abstract in Swedish I detta arbete har utvecklats automatiserade system för analys av miljöprover och av biologiska material. Två olika membranbaserade provupparbetningsmetodiker har använts för provförberedelse tillsammans med olika typer av kromatografi för själva analysen. Dessa principer har applicerats på tre olika tillämpningsområden. Extraktion med vätskemembran har kopplats med etThe main objective of this work was to construct practical analytical systems for the analysis of environmental and biological samples, using membrane-based techniques for sample pretreatment and chromatography for final analysis. Two types of membrane processes have been applied, with emphasis on automation. The supported liquid membrane (SLM) extraction was carried out in an automated continuou
How can qualitative, ethnographic and emotional aspects from probe users be mapped at the same time as they get something meaningful in return? The emphasis is here on intellectual rewards during probe work rather than future good designs that in a long term perspective can be beneficial for the probe user. This case study has elaborated the traditional use of cultural probes [1] with a selection
Critical infrastructures provide society with services that are essential for its functioning and extensive disruptions of these give rise to large societal consequences. Vulnerability analysis gives important decision information concerning improving their ability to withstand strains. To analyze vulnerabilities in infrastructures models for estimating consequences due to failures are needed. Con
Based on a case study of a telecom company’s transition towards more software value in their products, we describe and discuss SCM issues related to when traditional manufacturers go from a “hardware focus” to a mixed product configuration. Although software supply chain is not much discussed in logistics, it seems that logistics/SCM frameworks also fit many software supply issues. A specific soft
Reduction of energy use constitutes as an important measure for climate change mitigation. Buildings today account for 40% of the world’s primary energy use and 24% of the greenhouse gas emissions [International Energy Agency (IEA) 2011]0. The concept of passive houses is one of many necessary measures for climate change mitigation. To reach the passive house ambition in cold climates, increased t
A 7th order polyphase G/sub -m/C IF filter with automatic frequency tuning, implemented in a 0.35/spl mu/m CMOS process, is presented. The filter has a center frequency of 3MHz and a passband of 1MHz. The image band rejection is higher than 57dB, the stop band attenuation is at least 40dB. The in-band spurious free dynamic range is around 53dB. On-chip automatic frequency tuning provides more than
With increased market competition and advances in modern manufacturing technologies, requirements on customer orders and manufacturing conditions have become more diversified. This paper addresses a dynamic production planning problem for a steel plate fabrication plant with practical flexibility of both customers and manufacturing, such as steel slab-plate matching rules, plate substitution optio
Quality requirements complement functional requirements with information on the target quality levels of software functions or emergent system quality aspects. In release planning the allocation of development effort in further investments into product enhancements, new or enhanced functions are competing with quality improvements for limited resources. When setting balanced quality targets for de
