  1. 41. Shapes of pipes

    Författare :Valerio Lupi; Philipp Schlatter; Ramis Örlü; Jean-Christophe Robinet; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Global stability; curved pipes; secondary flow; wall-bounded turbulence; Global stabilitet; krökta rör; sekundärflöde; turbulens; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Curved pipes are ubiquitous in several industrial applications and biological systems. The study of flows through these configurations is therefore of significant practical interest.In the present thesis, the modal stability of flows in both toroidal and spatially developing bent pipes is investigated to understand the onset of transition.

  3. 42. Some Extensions of Fractional Ornstein-Uhlenbeck Model : Arbitrage and Other Applications

    Författare :José Igor Morlanes; Andriy Andreev; Hans Nyquist; Henrik Hult; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fractional Ornstein-Uhlenbeck process; insider information; simulation embedding method; jump times; least-squares estimator; likelihood process; Ito calculus; Malliavin calculus; stochastic calculus; Statistics; statistik;

    Sammanfattning : This doctoral thesis endeavors to extend probability and statistical models using stochastic differential equations. The described models capture essential features from data that are not explained by classical diffusion models driven by Brownian motion.New results obtained by the author are presented in five articles.

  4. 43. On Statistical Methods for Safety Validation of Automated Vehicles

    Författare :Daniel Åsljung; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; performance evaluation; extreme value theory; Automotive; validation; automated vehicles; simulation; verification; automated driving systems;

    Sammanfattning : Automated vehicles (AVs) are expected to bring safer and more convenient transport in the future. Consequently, before introducing AVs at scale to the general public, the required levels of safety should be shown with evidence. However, statistical evidence generated by brute force testing using safety drivers in real traffic does not scale well. LÄS MER

  5. 44. Relational Networks and Family Firm Capital Structure in Thailand : Theory and Practice

    Författare :Suranai Chuairuang; Barbara Cornelius; Håkan Boter; Anura De Zoysa; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Networks; relationships; capital structure decisions; family firm; small firm; information asymmetry; pecking order hypothesis; företagsekonomi; Business Studies;

    Sammanfattning : Firms must access capital to remain in business.  Small firms have greater difficulty accessing financial resources than have large firms because of their limited access to capital markets.  These difficulties are exacerbated by information asymmetries between a small firm’ s management and capital providers.

  7. 45. Unpacking Rational Use of Antibiotics : Policy in Medical Practice and the Medical Debate

    Författare :Hedvig Gröndal; Tora Holmberg; Ericka Johnson; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Antibiotics; Policy; Medical Sociology; Actor-Network Theory; Human-microbial relations; Antimicrobial Resistance; Everyday Infections; Material semiotics; Medical sociology; Medical objects; Medical technologies; Medical knowledge; Sociologi; Sociology;

    Sammanfattning : Rational use of antibiotics–using antibiotics only when needed and in the right way–is a prioritized goal in policy aimed at preventing antimicrobial resistance. A vast body of research is devoted to understanding why unnecessary antibiotics are prescribed. LÄS MER
