A GUI for online presentation of steel and steelmaking ladle temperature data and simulation.

Continuous casting is a casting process that produces steel slabs in a continuous manner with steel being poured at the top of the caster and a steel strand emerging from the mould below. Molten steel is transferred from the AOD converter to the caster using a ladle. The ladle is designed to be strong and insulated. Complete insulation is never achieved. Some of the heat is lost to the refractories by convection and conduction. Heat losses by radiation also occur. It is important to know the temperature of the melt during the process. For this reason, an online model was previously developed to simulate the steel and ladle wall temperatures during the ladle cycle. The model was developed as an ODE based model using grey box modeling technique. The model’s performance was acceptable and needed to be presented in a user friendly way. The aim of this thesis work was basically to design a GUI that presents steel and ladle wall temperatures calculated by the model and also allow the user to make adjustments to the model. This thesis work also discusses the sensitivity analysis of different parameters involved and their effects on different temperature estimations.

Sports and mediatization : a case of women´s ski-jumping

Ski jumping was the only sport included in the Winter Olympics, where women were not allowed to take part until the first week of April 2011, when IOC decided to let them in to the Olympic family, a major victory for women´s ski-jumping. Since 2004 the Norwegian media had women ski jumping as one important topic in their media coverage. The third of March 2010 the new Holmenkollen ski-jumping hill was inaugurated. It had been rebuilt for the World Championships 2011. The first jump on the hill was surrounded by an intense debate. Annette Sagen was decided to be the first jumper on the hill after a poll on the social media channel Facebook that gave Annette Sagen over 40 000 votes.  However Tuesday the second of March Björn Einar Romören, a world cup jumper, did the first jump during a training session. This act started a significant chain of events. The biggest Norwegian web – magazines Verldens Gang and Aftenposten made this the head story and they invited the readers to interaction. Within 24 hours 11 000 comments were written, most of them in favor of Sagen and against Romören´s behavior. The Norwegian Ski Association excluded Romören from two World Cup competitions. What did happen during these days in the media?  I want to present the activities, which went on in two web-magazines, and analyze the articles written on the topic. Main issues are to show what an impact a social media network had on the sport in this specific case and how different actors appeared in the media and discuss if Romörens exclusion was a result of the mediatization.
