   Abstract : In the production of paper, the quality of the pulp is an important factor both for the productivity and for the final quality. Reliable real-time measurements of pulp quality are therefore needed. READ MORE

4. 2. Feedback Control of Robotic Friction Stir Welding

   Author : Jeroen De Backer; Gunnar Bolmsjö; Anna-Karin Christiansson; Jorge Dos Santos; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; Process automation; Temperature control; Force control; Deflection model; Robotics; Svetsning; FSW; processtyrning; temperaturstyrning; robot; utböjning; kraftstyrning; Industriell arbetsvetenskap; Industrial engineering; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.

5. 3. Optimized processes in sawmills

   Author : Carl Gustav Lundahl; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Technology; Träteknik;

   Abstract : This work was initiated in order to show the potential for Swedish sawmills to achieve higher productivity by implementation of improved process control tools in breakdown and production flows. Accessible and reliable production data are crucial information concerning the area of process control; hence the objective in this study was to create a "toolbox" of suitable tools for decision support, surveys and analyses.

6. 4. Geometrical and dimensional Measurement Planning : - a systematic and holistic approach

   Author : Richard Lindqvist; Lars Mattsson; Martin Helgoson; KTH; []
   Keywords : Geometrical; dimensional; measurement planning; controllability; GMCP; quality assurance matrix and methodology; QAM; critical key characteristic;

   Abstract : För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras.

7. 5. Public procurement of engineering services : Task characteristics, control modes and effects on adaptability

   Author : Klara Granheimer; Tina Karrbom Gustavsson; Per-Erik Eriksson; Göran Lindahl; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; client; construction management; engineering services; organizational control; public procurement; beställare; infrastrukturprojekt; offentlig upphandling; organisationsteori; tekniska konsulttjänster; Real Estate and Construction Management; Fastigheter och byggande;

   Abstract : Previous research has emphasized the importance of engineering services and adaptability in the early stages of construction projects. Public clients usually procure engineering services from private companies, which makes their procurement strategies important in creating incentives for adaptability and innovation for the service providers.
