1. 16. Effects of Testing and Enactment on Memory

   Författare :Veit Kubik; Lars-Göran Nilsson; Fredrik Jönsson; Jonas Olofsson; Monika Knopf; Mihály Racsmány; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; testing effect; test-potentiated learning; enactment effect; cued recall; forgetting; episodic memory; Psychology; psykologi;

   Sammanfattning : Learning occurs not only when we encode information but also when we test our memory for this information at a later time. In three empirical studies, I investigated the individual and combined effects of interleaved testing (via repeated rounds of study and test practice) and encoding (via motor enactment) during learning on later cued-recall performance for action phrases.

3. 17. First-principles theory of electrically-induced spin and orbital magnetization

   Författare :Leandro Salemi; Peter M. Oppeneer; Yuriy Mokrousov; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spin-orbit torque; spin Hall effect; Rashba-Edelstein effect; spin Nernst effect; relativistic DFT; spin-orbitronics;

   Sammanfattning : Spin-orbit torques (SOTs) have emerged recently as practical tools to control the magnetization in spintronic devices, but it is debated what the underlying fundamental processes are that enable fast and energy-efficient magnetization switching.In this thesis, we investigate theoretically possible means of controlling magnetization in magnetic materials and heterostructures.

4. 18. Inclusions and/or Particles Engineering for Grain Refining Purposes in Ferritic Fe-20mass%Cr alloys

   Författare :Jesper Janis; Pär Jönsson; Keiji Nakajima; Lauri Holappa; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inclusions; Particles; Grain size; High Cr; Ferritic; Grain refining; Solidification; Pinning effect; Stainless steel; Oxides; Nitrides; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : Compared to more common used austenitic stainless steels, ferritic stainless steels contain very low amounts of the expensive alloying element Ni. In addition, they have good corrosion properties, but are sometimes suffering from poor weldability and bad mechanical properties. LÄS MER

5. 19. Competition, Division and Unity : The Impact of Market Structures on Trading Quality

   Författare :Chengcheng Qu; Björn Hagströmer; Lars Nordén; Michał Dzieliński; Roman Kozhan; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Market microstructure; latency arbitrage; fragmentation; tick size; lot size; liquidity; adverse selection; market efficiency; Business Administration; företagsekonomi;

   Sammanfattning : The financial market operates as an ecosystem, involving diverse yet interconnected marketplaces and participants. Market design, intricately interacting with technology, regulation, and competition, shapes how participants adapt their trading behavior and therefore influences market performance. LÄS MER

7. 20. On the in-plane mechanical properties of birch plywood

   Författare :Tianxiang Wang; Magnus Wålinder; Roberto Crocetti; Bo Källsner; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Birch plywood; in-plane mechanical properties; load-to-face grain angle; failure criteria; size effect; moisture; Björkplywood; mekaniska egenskaper i planet; belastningsvinkel relativt ytfaneren; brott kriterier; storlekseffekt; fukt; Building Materials; Byggnadsmaterial;

   Sammanfattning : Birch plywood has favorable mechanical properties that could be used in new types of connections for timber structures, and thus enable a substitution of the current system with steel plates. Such new connections could result in significant advantages in terms of environmental impact and economy as well as ease of prefabrication and mountability. LÄS MER
