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

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

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

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

A charge sampling mixer with embedded and programmable filter function is described, which is not based on the conventional sub-sampling but the proposed bandpass charge sampling (BPCS) principle. A BPCS circuit samples a radio signal by integrating the weighted current of the clocked radio signal in n clock cycles. The large sampling capacitor used in the circuit results in low noise and low char

Vid effektivitetsrevision i statsförvaltningen används genomslag ofta som ett mått på framgång för en NAO (National Audit Office). Media spelar en viktig roll för genomslaget, i synnerhet när det saknas beredningskrav för granskningarna i riksdagen. Relationen till media kan vara problematisk på flera vis och äventyra granskningsmyndighetens oberoende och trovärdighet. I detta papper diskuteras m
