  1. 31. Development of a Free Surface Capability in a RANS Solver with Coupled Equations and Overset Grids

    Författare :Michal Orych; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-surface; overset; RANS;

    Sammanfattning : This thesis is a result of investigations carried out during the implementation of a free surface capturing method in a RANS solver. The work consists of two distinct parts which complement each other, and the purpose is to improve the free surface interface sharpness and to reduce numerical diffusion of the gravity waves.

  3. 32. Developing a Value Proposition of Maritime Ergonomics

    Författare :Cecilia Österman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; operational performance; socio-technical systems.; Ergonomics; value proposition; maritime economics; human element; shipping; participatory ergonomics;

    Sammanfattning : There is a large body of knowledge available on the importance of ergonomics for successful(and unsuccessful) systems. Domain specific handbooks, guidelines and standards can befound also for the maritime industry. LÄS MER

  4. 33. Technology Carriers: The Role of Engineers in the Expanding Swedish Shipbuilding System

    Författare :Lars O. Olsson; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; sociotechnical systems; shipbuilding; engineering education; 20-th century; user-producer interaction; professional associations; engineers; technological systems; technological knowledge; history of technology; systems of innovation; industrial research;

    Sammanfattning : This study analyses the process which shaped the role or function of college-trained engineers within a technological system or innovation system during the period from the start of the 20th century until the 1950s and 1960s. With a conceptual framework of sociotechnical systems and of engineers as a social group of technology carriers this process is studied in one particular system, namely the Swedish shipbuilding system.

  5. 34. Huvudbaner och anvapen under stormaktstiden

    Författare :Inga von Corswant-Naumburg; Hans Soop; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ancestral Coat of arms; Baroque; Ceremonial; Contract for a Sculpture; Funeral; Funeral Escutcheon; Heraldry; Sculptor; Sweden as a Great Power; 17th-Century Crafts; konstvetenskap; Art History;

    Sammanfattning : This is the first major piece of research which has been carried out dealing with funeral escutcheons and ancestral coats of arms which are typical of the period when Sweden was a great power. Funeral escutcheons and ancestral coats of arms are wooden shields which were often carried at noblemen’s funerals and afterwards were hung in the church where the funeral service took place.

  7. 35. Fully Nonlinear Unsteady Three-Dimensional Boundary Element Method for Ship Motions in Waves

    Författare :Martin Kjellberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BEM; potential flow; MEL; ship motions; free surface; wave resistance; fully nonlinear; time-dependent;

    Sammanfattning : The prediction of the behavior of ships in a seaway has been an important topic in ship design since the beginning of modern naval architecture. In recent years, computer simulations using numerical methods based on mathematical models of the ship hydrodynamics problem has become a valuable tool for researchers and engineers working in this field.
