1. 1. Human-centred design for maritime technology and organizational change

   Författare :Nicole Almeida Costa; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; participatory ergonomics; organizational change; technology acceptance; digitalization; systems theory; e-Navigation; human-centred design;

   Sammanfattning : Context: The shipping industry is undergoing a transitional phase at different levels, including IMO’s e-Navigation initiative, and with this comes the need to use a human-centred design (HCD) approach to avoid accidents linked to automation issues, and to cater for the maintenance of safety and efficiency within this global transport system. Aims: The aim of this thesis is to investigate the value and challenges in HCD practice and how ergonomics/human factors (E/HF) principles can be introduced, as well as what gaps and opportunities exist in current standard operations and technologies in navigation that can potentially be followed upon by future e-Navigation developments, not only from a technological perspective but also regulatory, operational etc. LÄS MER

3. 2. Plasmonics with a Twist: from Single Particles to Metasurfaces

   Författare :Robin Ogier; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; colloidal lithography; localized surface plasmons; circularly polarized light; metsurfaces; nanofabrication; chirality; optical trapping;

   Sammanfattning : Nanophotonics deals with how electromagnetic fields can be confined and squeezed to orders of dimensions below the light wavelength. Plasmonics, one of the fields of nanophotonics, study collective free electron oscillations driven by light in metallic nanostructures and interfaces. LÄS MER

4. 3. Technological Change in an International Industrial System

   Författare :Leif Linnskog; Ulf Johanson; Peter Söderbaum; Hans Hasselbladh; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology; technological change; industrial networks; business relationships; strategic intention; power; negotiations; social capital; coalitions; structural inertness; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi; Industriell ekonomi och organisation;

   Sammanfattning : Industrial systems resist change, more often, because heavy production facilities and industrial constructions are expensive and have long economic lives, but also because people tend to defend ingrained conceptions of how things are and how activities ought to be performed. Starting out from the question: “How does technological change come about in an international, industrial system?” the thesis investigates the interplay between technological, social, and economic factors.

5. 4. Thermal and Photon Stimulated Reactions on Metal Particles

   Författare :Kristina Wettergren; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plasmons; Platinum Clusters; Platinum Nanoparticles; Hydrogen Oxidation; Sodium; Silver Nanoparticles; Nitric Oxide; Photodesorption; Sintering; Graphite; Water;

   Sammanfattning : The interaction between molecules and solid surfaces influence our daily lives in many ways. One important example is heterogeneous catalysis where surface reactions, for example, are used for production of chemicals and exhaust after-treatment. LÄS MER

7. 5. Dynamiskt belastade tribologiska system under plastisk formning, del II --- analyserade genom akustisk emission

   Författare :Thomas Skåre; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Mechanical engineering; supervision; wear; waves; vibrations; tribology; surfaces; stick-slip; sliding; sheet metal; quality check; plastic forming; monitoring; galling; machining; deep drawing; friction; cracking; contact surfaces; Acoustic emission AE ; contact pressure; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Material technology; Materiallära; materialteknik; Production technology; Produktionsteknik;

   Sammanfattning : The dynamic friction process and contact surface between tool and working material in a plastic forming process is hard to describe in mathematical form and hard to monitor and control in real time. High production speed and highly optimised forming operations result in great demands on the control equipment. LÄS MER
