Gas turbine maintenance is crucial due to high cost for the replacement of its components and associated loss of power during shutdown period. Conventional scheduled maintenance, based on equivalent operating hours, is not the best alternative as it can require unnecessary shut downs.

Ungdomars engagemang i föreningsverksamhet och organisering förutsägs ofta á priori vara något bra. Mer sällan problematiseras frågan, t.ex. genom att ställa frågan vem som organiserar sig. Denna artikel utgår från litteraturen om socialt kapital och har bl.a. tagit intryck av Bourdieus modell för socialt kapital. I en ekonomisk modell med inspiration från Bourdieu kommer värdet av en individs so

A threshold analysis of terminated generalized LDPC convolutional codes (GLDPC CCs) is presented for the binary erasure channel. Different ensembles of protograph-based GLDPC CCs are considered, including braided block codes (BBCs). It is shown that the terminated PG-GLDPC CCs have better thresholds than their block code counterparts. Surprisingly, our numerical analysis suggests that for large te

Hur ställer sig samhället till en samverkan mellan universitetsforskare, som själva vill delta i den fortsatta kommersialiseringen, och industriella aktörer – dominanten eller utmanarna? Svaret har en tydlig EU-koppling och berör ett centralt satsningsområde för unionen, men hänsyn måste också tas till EU-rättens krav på att en effektiv konkurrens bevaras på viktiga innovationsmarknader.

One of the broken promises of democracy is the failure of the market in guaranteeing a vigorous political debate. The European Court of Human Rights has ascribed to the press the vital role of Public Watchdog, making it incumbent on it to

Många pensionssystem är ohållbara. Sverige är ett av de länder som lyckats genomföra en pensionsreform. Kapitlet ger en politisk-ekonomisk analys av hur detta var möjligt.

Popular Abstract in English In May 1619, the Finnish astrologer Sigfridus Aronus Forsius (d. 1624) was examined by clerical authorities. In the verdict, astrology was rejected as a pagan craft, forbidden for any Christian. Yet still astrology was inseparable from the scholarly conception of the world. The principles of astral influence were more or less self-evident in physical theory and in medicThe purpose of this thesis is to analyse a displacement of the limits between allowable and illicit knowledge in the orthodox, Lutheran discourse of early modern Sweden. Focusing on the debate over astrology, exemplified in the works of Laurentius Paulinus Gothus (1565-1646) and Sigfridus Aronus Forsius (d. 1624), the thesis aims to challenge the view of how the Reformation, regarded as a prelimin
