    Sammanfattning : The effects of greenhouse gas net emissions on global warming, stricter legislation on waste handling, and the pursuit of ever cheaper heat- and power production are all important factors driving the introduction of complex fuels in incineration plants. However - without fundamental knowledge regarding ash transformation, corrosion control, and materials selection – this introduction of potentially economically and environmentally beneficial fuels, might instead cause economic loss and environmentally adverse effects.

  3. 2. Towards a learning system for process and energy industry : Enabling optimal control, diagnostics and decision support

    Författare :Moksadur Rahman; Konstantinos Kyprianidis; Anders Avelin; Bengtsson Gunnar; Agostino Gambarotta; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Learning system; Supervisory system; Pulp and paper; Micro gas turbine; Process modelling; Model-based control; Diagnostics; Decision support; Anomaly detection; Fault detection; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Driven by intense competition, increasing operational cost and strict environmental regulations, the modern process and energy industry needs to find the best possible way to adapt to maintain profitability. Optimization of control and operation of the industrial systems is essential to satisfy the contradicting objectives of improving product quality and process efficiency while reducing production cost and plant downtime.

  4. 3. Ortnamnsanpassning som process : En undersökning av vendiska ortnamn och ortnamnsvarianter i Knýtlinga saga

    Författare :Alexandra Petrulevich; Henrik Williams; Staffan Nyström; Michael Lerche Nielsen; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; place-name replication; place-name adaptation; Old Norse; Knýtlinga saga; Wendish place-names; contact onomastics; philology; ortnamnsreplikation; ortnamnsanpassning; fornvästnordiska; Knýtlinga saga; vendiska ortnamn; kontaktonomastik; ortnamnsvariant; filologi; Pommern; vender; språkkontakt; polabiska; pomoranska; Nordiska språk; Scandinavian Languages;

    Sammanfattning : The aim of the thesis is to theoretically and empirically describe and explain the phenomenon of place-name adaptation which does not necessarily end with the borrowing or replication of place-names but can continue further. 48 Wendish place-names in Knýtlinga saga, including their attestations and variants in a selection of the saga’s text carriers and corresponding text witnesses, constitute the primary material for the investigation.

  5. 4. Pawsitive selection : Genetics of dog-human communication

    Författare :Mia Persson; Per Jensen; Lina Roth; Dominic Wright; Ádám Miklósi; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Through domestication and recent selection, dogs have evolved a unique set of communicative skills to attract and redirect human attention. These social skills have not been seen to the same extent in socialised wolves and are therefore believed to have a significant genetic basis. LÄS MER

  7. 5. Tools for Autonomous Process Control

    Författare :Anders Wallén; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential control; software architectures; fast set point response; spectral estimation; frequency domain identification; relay feedback; non-linear system identification; Autonomous Control; Process Control; Grafcet; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor.
