  1. 36. Numerical Modeling of Atomization in Spray Systems

    Författare :Michele Pütz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; spray modeling; quadrature-based moment methods; atomization; numerical simulation; Multiphase; population balance equations;

    Sammanfattning : Dispersed multiphase flows refer to dynamic systems comprising two or more phases where at least one phase is in the form of fine particles evolving in and interacting with a surrounding fluid. Spray systems fall into that category. LÄS MER

  3. 37. Thin Films and Multilayers of Yba2Cu3O7-δ and Srtio3; Growth, Characterization, And secondary Phase Formation

    Författare :Niclas Edvardsson; Michael Karkut; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Sputter-deposited thin films and multilayers of YBa2Cu3O7-δ (YBCO) and SrTi03 (STO) have been grown and studied. Microstructure in general, and formation of secondary phases, in particular, have been studied in relation to growth conditions. LÄS MER

  4. 38. Studies of transport in oxides on Zr-based materials

    Författare :Clara Anghel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zirconium; hydrogen; oxygen diffusion; second-phase particle; oxidation; dissociation; hydration; carbon monoxide; adsorption; porosity; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Zr-based materials have found their main application in the nuclear field having high corrosion resistance and low neutron absorption cross-section. The oxide layer that is formed on the surface of these alloys is meant to be the barrier between the metal and the corrosive environment. LÄS MER

  5. 39. CFD and data-driven modeling for safe spillway discharge

    Författare :Shicheng Li; Anders Ansell; James Yang; Robert Boes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discharge safety; hydraulic design; spillway; discharge capacity; aerator; two-phase flow; air entrainment; energy dissipation; CFD; data-driven modeling; Betongbyggnad; Concrete Structures;

    Sammanfattning : A spillway is a crucial dam structure that regulates water levels and prevents the dam from overtopping. The majority of the dams in the world were constructed before the 1980s. Compared to the current design flood standards, many spillways are undersized, e.g. LÄS MER

  7. 40. Movement Control after Stroke : Studies on Sit-to-walk and on the Relations between Clinical and Laboratory Measures

    Författare :Gunilla Elmgren Frykberg; Jörgen Borg; Helga Hirschfeld; Charlotte Häger-Ross; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; sit-to-walk; movement analysis; force analysis; postural control; Berg Balance Scale; Physiotherapy; Sjukgymnastik fysioterapi; Rehabilitation Medicine; Rehabiliteringsmedicin;

    Sammanfattning : Aims: The principal aims of this research were 1) to extend existing knowledge of the everyday sit-to-walk (STW) transfer in subjects with stroke and in matched controls by exploring temporal, kinematic, and kinetic aspects, and 2) to investigate the relations between some clinical and laboratory measures of postural control and locomotion in stroke rehabilitation and research. Methods: Ten community-living subjects with stroke (mean age 59 years) and ten matched controls were enrolled in the STW studies (Studies I, II, and IV). LÄS MER
