  1. 1. Weld Pool Simulations

    Author : Marcus Edstorp; Högskolan Väst; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Arc Welding; Weld Pool; Multiphysics Simulations; Moving Boundaries; Free Surfaces; Mesh Motion; Two-Phase Flow; Incompressible Flow; Electromagnetics; Finite Element Methods; Applied mathematics; Tillämpad matematik; Manufacturing engineering; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling.

    Abstract : After several years of disussions, tests, investigations and additional tests, the suppliers and retailers within the Swedish business sector for food and commodities formed a jointly owned, non-profit company in 1997, which subsequently started in physical operations in 2000. This company, Svenska Retursystem AB (www.retursystem. READ MORE

  4. 4. Essays on Behavioral Economics and Fisheries: Coordination and Cooperation

    Author : Lisa Björk; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public good; conditional cooperation; experiment; uncertainty; risk; ambiguity; common pool; TURF; co-management; coordination; shrimp; ITQ; fisheries; social network;

    Abstract : Kapitel 1: Samarbete under risk och sann osäkerhet (ambiguity). Avkastningen på investeringar i kollektiva nyttigheter är nästan alltid osäker till skillnad från den design som används i ekonomiska experiment i den rådande empiriska litteraturen. READ MORE

  5. 5. Simple Models for Complex Nonequilibrium Problems in Nanoscale Friction and Network Dynamics

    Author : David Andersson; Astrid de WIjn; Supriya Krishnamurthy; Nicola Manini; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; tribology; nanofriction; 2d materials; graphene; image reconstruction; social dynamics; common-pool resource; collective action; simple models; Theoretical Physics; teoretisk fysik;

    Abstract : This doctoral thesis investigates three different topics: How friction evolves in atomically thin layered materials (2D materials); How social dynamics can be used to model grand scale common-pool resource games; Benchmarking of various image reconstruction algorithms in atomic force microscopy experiments. While these topics are diverse, they share being complex out-of-equilibrium systems. READ MORE
