Hygrothermal conditions in exterior walls for passive houses in cold climate considering future climate scenario

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

Imitation, Line-up selection and Semantics

Recent studies have shown that the ability to recognize an imitated voice is affected by topic and familiarity with the person being imitated. These studies have used professional imitations of a well-known politician. In one of the training passages is a political text and in the other a text explaining how to bake a cake. The signal detection methods used in these recent studies gave no specific

Real time observation of ultrathin epitaxial oxide growth during alloy oxidation

We have studied the thermal oxidation of the intermetallic alloy CoGa in situ, in real time on the atomic scale, during the growth of an ultrathin, epitaxial Ga oxide layer. On the basis of an extended set of surface x-ray diffraction data, density functional theory calculations and core level spectroscopy data, we find that the oxide film consists of an oxygen ion double layer, which contains the

Agency autonomy - not that stable?

Building on the idea of path-dependency, studies on agency autonomy typically assume that de facto autonomy is relatively stable over time within national politico-administrative contexts. This assumption is challenged in this paper, which maintains that de facto autonomy may just as well be understood as a state in constant flux. The paper highlights the limitations of historical institutionalism

Biocatalysis in Organic Media: Parameters Influencing Activity, Stability and Enantioselectivity

Biocatalysis in organic media offers very attractive methods to prepare fine chemicals. The biocatalyst performance regarding activity, stability and enantioselectivity will determine the viability of the bio-process. Therefore, the understanding and optimization of the parameters influencing enzyme performance in organic solvents are extremely important. In this thesis, reactions catalysed by hyd

Valid inequalities for a shortest-path routing optimization problem

In autonomous systems of the Internet packets are routed on shortest paths to their destinations, for example according to the ECMP principle. The problem of finding a feasible traffic routing configuration realized on paths which can be generated by a system of weights assigned to IP links is NP-hard. This problem can be formulated as a mixed-integer program and attempted with a branch-and-cut al
