  1. 6. Composite Bridges : Innovative ways of achieving composite action

    Författare :Robert Hällmark; Peter Collin; Ian May; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composite action; bridges; steel; concrete; shear connectors; prefabrication; coiled spring pins; shear studs; post-installation; design guidance; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The topic of this thesis is steel-concrete composite bridges and innovative ways of achieving composite action. The typical superstructure consists of three main components: the steel girders, the concrete deck slab and the shear connectors. LÄS MER

  3. 7. Prefabricated composite bridges : a study of dry deck joints

    Författare :Robert Hällmark; Ian May; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge construction; prefabrication; monitoring; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business.

  4. 8. A Chemometric Approach to Process Monitoring and Control - With Applications to Wastewater Treatment Operation

    Författare :Christian Rosén; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotics; Automation; Elektroteknik; Electrical engineering; wastewater treatment; supervisory control; simulation; process monitoring; principal component analysis PCA ; multivariate statistics; modelling; activated sludge; detection; control engineering; Automatiska system; robotteknik; reglerteknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : In this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. LÄS MER

  5. 9. Phase Equilibria and Structures of Oppositely Charged Polymers and Surfactants in Water

    Författare :Anna Svensson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; self diffusion; PFG NMR; hexagonal; cubic Pm3n; liquid crystals; SAXS; polymer; counterion; complex; polyelectrolyte; surfactant; Monte Carlo simulations; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : A new approach to the study of aqueous mixtures of oppositely charged polymers and surfactants has been introduced. Pure polyion-surfactant ion complex salts have been synthesized and used as the point of departure. The elimination of the simple ions reduces the number of components in the mixtures, thus greatly simplifying the system. LÄS MER

  7. 10. Modeling and Control of Stiff Robots for Flexible Manufacturing

    Författare :Isolde Dressler; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To survive on a global market, small and medium size enterprises (SMEs) require affordable and competitive industrial automation for high quality flexible manufacturing. This thesis contributes to the development of robot concepts that fit the needs of SMEs. LÄS MER
