  2. 1. Progressives in use and contact : A descriptive, areal and typological study with special focus on selected Iranian languages

    Author : Ghazaleh Vafaeian; Östen Dahl; Agnes Korn; Maria Koptjevskaja Tamm; Pier Marco Bertinetto; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; progressive; use; contact; areal; parallel corpora; typology; grammaticalization; Iranian; Persian; Mazandarani; Gilaki; Taleshi; Tati; Linguistics; lingvistik;

    Abstract : Progressives are grammatical patterns primarily used to refer to events that are ongoing at a specific time. This thesis investigates uses of such patterns in a number of languages as well as the interaction of a number of progressives in contact. READ MORE

  4. 2. Cam Roller Contact : Surfaces and Tribology

    Author : Frédéric Cabanettes; Bengt-Göran Rosén; Ulf Olofsson; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wear reduction; camshaft; roller; surface topography; relocation; elasto plastic rough contact; elasto hydrodynamic lubrication; Mechanical engineering; Maskinteknik;

    Abstract : The automotive industry and the design of engines are strongly ruled by performance and legislation demands. In the valve train, mechanical components such as camshafts and rollers are defined by specifications including more and more constraints concerning their ability to face wear thus prolonging lifetime.

  5. 3. Wheel-rail contact modelling in vehicle dynamics simulation

    Author : Matin Shahzamanian Sichani; Mats Berg; Roger Enblom; Elena Kabo; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wheel-rail contact; non-elliptic contact; vehicle-track interaction; rail vehicle dynamics; rolling contact; MBS; virtual penetration; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Fordonsteknik; Järnvägsgruppen - Tribologi; The KTH Railway Group - Tribology;

    Abstract : The wheel-rail contact is at the core of all research related to vehicle-track interaction. This tiny interface governs the dynamic performance of rail vehicles through the loads it transmits and, like any high stress concentration zone, it is subjected to serious damage phenomena.

  6. 4. The Plasma Contact System : New Functional Insights from a Hemostatic and Thrombotic Perspective

    Author : Jennie Bäck; Bo Nilsson; Kristina Nilsson Ekdahl; Ulla Hedner; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Contact activation; factor XII; platelets; coagulation; antithrombin; C1 inhibitor; hemostasis; biomarkers; vascular disease.; Klinisk immunologi; Clinical Immunology;

    Abstract : The physiological role of the plasma contact system still remains a partial enigma. The aim of the presented work was to expand our understanding of the plasma contact system, focusing on its physiological activation and function, principally from a hemostatic perspective. It also explored contact system activation under pathological conditions. READ MORE

  7. 5. Development Towards Sustainable Ironmaking : The IronArc Process

    Author : Jonas Svantesson; Mikael Ersson; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IronArc; Refractory wear; plasma generator; freeze-lining; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The IronArc process is a novel process for a more sustainable production of liquid pig iron using electricity for heating and hydrocarbons for reduction. This thesis aims to facilitate its use by investigating possible refractory solutions and the gas blowing in the process which is done by a plasma generator. READ MORE
