Time-Domain Nu-Gap Robustness Analysis for Shift-Invariant Systems

A nu-gap measure of distance between linear time-invariant systems is defined in terms of projections onto system graphs directly, without appealing to the existence of normalised strong graph representations as in the literature. A robust stability result is derived by exploiting an assumption on the compactness of a Hankel-type operator in a similar manner to recent developments on time-varying

Laccase from a Litter Degrading Fungus: Evaluation for Environmental Applications and Modification of Lignin to a Bioadhesive

Popular Abstract in Swedish The phenol oxidase “laccase” was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. However, its use in one of the oldest biotechnologies, i.e. the making of lacquerware in East-Asia, dates back to 5000-6000 BC. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes one elecLaccase, the phenol oxidizing enzyme, was first described towards the end of the 19th century from the wound sap of the lacquer tree Rhus vernicifera. The enzyme has the widest distribution in nature among the multicopper oxidases. It catalyzes single electron transfer oxidation in the presence of molecular oxygen producing water as by-product. Based on these highly desired mild oxidising conditio

Manual annotation of evaluative language expressions : bridging discourse and corpus approaches

The analysis of evaluation in text poses significant methodological challenges, which mainly arise from the fact that: a) evaluative meanings can be expressed through an open-ended range of lexico-grammatical resources; b) they can span multiple words; c) context and co-text play a key role in determining the evaluative meaning of words or phrases; d) the interpretation of evaluation in text depen

Determination of Heavy Metals and Fluorine in Airborne Particulate Matter in an Indoor Environment by Simultaneous Use of PIXE and γ-Ray Detection

The current rapid development within work-environment research has created a considerable demand among industrial hygienists for suitable analytical methods. PIXE (particle-induced X-ray emission analysis), which was introduced in Lund in 1970, has been shown to be a feasible method for use in studying the elemental composition of aerosols. However, in some work environments, fluorine, an element
