Det är inte ett nätproblem vi har på halsen, det är mer världsligt än så. Men det betyder samtidigt att vi har många av lösningarna närmare än vi tror. Istället för att se allt som rör internet som svårt, läskigt eller rentav magiskt har vi redan det mesta som behövs nära till hands.

In production industry today a lot of engineering time is required to develop and maintain control applications. One part of the control applications are the state machines which typically are written in Grafcet/SFC. Several efforts have been made to extend Grafcet/SFC to achieve more effective and convenient development, e.g. by introducing hierarchical structuring, reusable sub-state machines, a

This study empirically tests DeLone and McLean IS success model in the context of a Business Intelligence (BI) system in a police organization. Based on a literature review, for the model’s first five dimensions, we generated a questionnaire. The questionnaire was distributed to the potential users of the BI system in the organization. Out of eight relationships tested, five were significant. The

Popular Abstract in Swedish Den här avhandlingen handlar om att skräddarsy mikroorganismer så att de kan utföra specifika kemiska reaktioner. Nästan alla material och produkter vi har omkring oss idag har framställts genom kemiska metoder. Ofta används olja vilken så småningom kommer sina, som utgångskemikalie. När de framställda produkterna sedan förbränns efter användning släpps koldioxid ut vilChiral building blocks are important molecules for synthesis of fine chemicals and pharmaceuticals. Biocatalysis has gained in relevance over traditional organic methods for synthesis of chiral compounds, as reactions can be performed at high enantio-selectivity and purity with environmentally friendly, simple, and cheap methods. The aim of the present study was to explore the feasibility of using

Rate R=(c-1)/c convolutional codes of constraint length nu can be represented by conventional syndrome trellises with a state complexity of s=nu or by binary syndrome trellises with a state complexity of s=nu or s=nu+1, which corresponds to at most 2^s states at each trellis level. It is shown that if the parity-check polynomials fulfill certain conditions, there exist binary syndrome trellises wi

Large-scale software development is a complex undertaking and generates an ever-increasing amount of information. To be able to work efficiently under such circumstances, navigation in all available data needs support. Maintaining traceability links between software artefacts is one approach to structure the information space and support this challenge. Several researchers have proposed traceabili

When the constructions from the industrial society are abandoned and start to decay, former workplaces gain a new potential. Through activities like urban exploration old abandoned factories become arenas for photographic expeditions. The photos are presented on websites and in books, and are characterized by a kind of postindustrial romanticism. Meanwhile other industrial settings are refurbished

In this paper the frequency domain sensitivity shaping of pole placement controllers is discussed. The sensitivity function is shaped in order to improve robustness and disturbance attenuation, and it is done with the use of controller overparametrization. A design example shows the capabilities of the method. The computation is done by a weighted least squares procedure which is suitable for adap

The anonymous Libellus de Magno Erici Rege gives an outline of King Magnus Eriksson’s reign, painting it in dark colours. The author emphasises that Sweden is an elective, not a hereditary kingdom, and that the king can be deposed if he commits evil deeds and turns into a tyrant. The detailed account of King Magnus’s reign is designed to show that he had wilfully and systematically broken the law,
