  2. 1. Defects in E-PBF Ti-6Al-4V and their Effect on Fatigue Behaviour : Characteristics, Distribution and Impact on Life

    Author : Viktor Sandell; Marta-Lena Antti; Pia Åkerfeldt; Thomas Hansson; Hans Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Defects; Additive Manufacturing; Ti-6Al-4V; Probabilistic Modelling; Fatigue; Materialteknik; Engineering Materials;

    Abstract : Layer by layer manufacturing (additive manufacturing, AM) of metals is emerging as an alternative to conventional subtractive manufacturing with the goal of enabling near net-shape production of complex part geometries with reduced material waste and shorter lead times. Recently this field has experienced rapid growth through industrial adaptation but has simultaneously encountered challenges. READ MORE

  4. 2. Slag/Metal Metallurgy in Iron and Steel Melts

    Author : Johan Ekengård; Pär Jönsson; Attila Dioszegi; Johan Björkvall; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenit; syreaktivitet; slagg; fördelning; primär dendrit; metalldroppar; lamellär grafit; svavel; kompaktgrafit; skänk; nodulär grafit; raffinering; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : In this work, the metal and slag phase mixing in three steps of a ladle refining operation of steel melts and for an oxygen balance during cooling of cast iron melts have been studied at two Swedish steel plants and at two Swedish cast iron foundries, respectively. In order to predict the oxygen activity in the steel bulk in equilibrium with the top slag as well as in metal droplets in the top slag in equilibrium with the top slag, three slag models were used.

  5. 3. Growth and decline in rural Sweden : geographical distribution of employment and population 1960–2010

    Author : Martin Hedlund; Linda Lundmark; Emma Lundholm; Olof Stjernström; Kjell Overvåg; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; rural restructuring; rural heterogeneity; manufacturing decline; agricultural decline; urbanization; rural typology; life-course perspective; cluster analysis; Sweden; Social and Economic Geography; kulturgeografi;

    Abstract : This thesis investigates the combination of changes in the population and employment into sectors in rural Sweden for the period 1960-2010. The aim is to describe and analyze the demographic changes together with the labour market changes, and to account for the spatial outcome of these changes by considering the heterogeneity of rural areas.

  6. 4. Cognition Seen Through the Eyes of Hearing Aid Users : Working Memory Resource Allocation for Speech Perception and Recall

    Author : Andreea Micula; Jerker Rönnberg; Elaine Hoi Ning Ng; Piers Dawes; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Working memory; Free recall; Pupillary responses; Noise reduction; Arbetsminne; Återgivning; Pupillmätning; Brusreducering;

    Abstract : This thesis investigates how hearing aid users allocate working (WM) memory resources under various task demands when listening to and storing speech in memory for later recall. This was done by combining an auditory recall task, the Sentence-final Word Identification and Recall (SWIR) test, with pupillometry. READ MORE

  7. 5. On the efficiency of the Bayesian bootstrap

    Author : Raul Cano; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Poisson-fördelning;

    Abstract : The efficiency of the Bayesian bootstrap is treated for large and small samples from infinite and finite populations. The Bayesian bootstrap is compared with nonparametric and parametric Bayesian methods in the infinite case, for large samples and considering the mean and truncation functionals. READ MORE
