  1. 1. Numerical modelling of swirling drying flow

    Author : Simon Johansson; Per Carlsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Waste hydrochloric acid (HCl) from the pickling process at SSAB EMEA in Borl¨ange, Sweden, is regenerated using a technique called spray roasting where waste HCl is sprayed into a hot reactor through four spray nozzles at the top of the reactor. The regeneration (drying) process is driven by four natural gas burners placed symmetrically along the periphery of the reactor and causes the water in the waste acid droplets to evaporate.

  2. 2. Towards better understanding of the flow inside industrial processes: a CFD study

    Author : Simon Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Computational Fluid Dynamics (CFD) is a method to numerically pre- dict flow patterns. In this thesis the method is used to predict the flow in a hydrochloric acid regeneration plant located at SSAB EMEA in Borl ̈ange and to investigate the flow in a burner region of a rotary kiln at LKAB in Kiruna.

  3. 3. Comeback Detroit : The return of whites and wealth to a Black city

    Author : Simon Johansson; Johan Lindqvist; Andrew Newman; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Detroit; Comeback; Urban Change; Gentrification; Race; Social Anthropology; socialantropologi;

    Abstract : Since the 1950s, the city of Detroit has declined in terms of demography and economic prosperity.  Once among the wealthiest and largest cities of America, Detroit now continually ranks as one of nations poorest, Blackest and most abandoned urban areas. READ MORE

  4. 4. Intelligent data acquisition for drug design through combinatorial library design

    Author : Simon Johansson; Chalmers tekniska högskola; []
    Keywords : HUMANIORA; HUMANITIES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; determinantal point processes; generative models; machine learning; drug discovery; active learning; Cheminformatics;

    Abstract : A problem that occurs in machine learning methods for drug discovery is a need for standardized data. Methods and interest exist for producing new data but due to material and budget constraints it is desirable that each iteration of producing data is as efficient as possible. READ MORE

  5. 5. Core-hole Clock Spectroscopy Using Hard X-rays : Exciting States in Condensed Matter

    Author : Fredrik Johansson; Andreas Lindblad; Carla Puglia; Tomas Edvinsson; Marc Simon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; core-hole clock; resonant Auger; XPS; black phosphorous; TMDC; perovskite; graphene; coincidences spectroscopy; synchrotron radiation; HAXPES;

    Abstract : This thesis is about how electrons move from one place to another, that is charge transfer dynamics. Charge transfer dynamics is an important property governing chemical and physical changes that form the base for many applications such as electronics, optoelectronics and catalysis. READ MORE
