  1. 1. Birds in the Flow: Flight Mechanics, Wake Dynamics and Flight Performance

    Författare :Mikael Rosén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Eleonora s falcon.; hunting; optimum wingspan; tail posture; wingbeat kinematics; wake topology; DPIV; flight performance; wake dynamics; flight mechanics; wind tunnel; Flight; bird;

    Sammanfattning : I share my fascination of bird flight with many others, and here I summarise my thesis on the subject. This thesis emphasises the mechanics of bird flight by focusing on flight mechanics, wake dynamics and flight performance. LÄS MER

  3. 2. New Perspectives on Analysis and Design of High-Speed Craft with Respect to Slamming

    Författare :Mikael Razola; Anders Rosén; Ermina Begovic; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : High-speed craft are in high demand in the maritime industry, for example, in maintenance operations for offshore structures, for search and rescue, for patrolling operations, or as leisure craft to deliver speed and excitement. Design and operation of high-speed craft are often governed by the hydrodynamic phenomena of slamming, which occur when the craft impact the wave surface. LÄS MER

  4. 3. On Structural Design of High-Speed Craft

    Författare :Mikael Razola; Jakob Kuttenkeuler; Anders Rosén; Olav Fredrik Rognebakke; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slamming; high-speed craft; finite-element analysis; design methods; experimental analysis; numerical simulations; design loads; statistical analysis;

    Sammanfattning : The development in structural design and construction of high-speed craft has been extensive during the last decades. Environmental and economical issues have increased the need to develop more optimized structures, using new material concepts, to reduce weight and increase performance efficiency. LÄS MER

  5. 4. Noticing nature : exploring more-than-human-centred design in urban farming

    Författare :Anton Poikolainen Rosén; Maria Normark; Mikael Wiberg; Ron Wakkary; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human-Computer Interaction; Sustainability; Posthumanism; Urban farming; design; design; human-computer interaction; människa-datorinteraktion;

    Sammanfattning : This thesis articulates, theorises and furthers the concept of “more-than-human-centred design” by studying the use and design of technology for noticing nature and caring for nature. The emerging field of more-than-human-centred design focuses on the mutual interdependence between humans and non-humans (e.g. LÄS MER

  7. 5. Flaskor på löpande band : Arbete och arbetskraftsrekrytering vid Surte glasbruk 1943-1978

    Författare :Gunnel Holmér; Ulla Professor (befordrad); Mikael Docent; Ann-Catrin Östman; Linnéuniversitetet; []
    Nyckelord :HUMANIORA; HUMANITIES; glass-work; glass-workers; labour immigration; gender division of labour; durable inequality; glasbruk; glasarbetare; arbetskraftsinvandring; könsarbetsdelning; beständig ojämlikhet; Historia; History;

    Sammanfattning : This dissertation considers how the transition from craft manufacture to mechanized glass production affected the organization of work and the consequences for the recruitment of labour. Based on gender and ethnicity, the dissertation studies the composition of the workforce, the significance of qualifications, and differences in career paths and length of stay have been investigated at Surte glassworks 1943–1978.
