1. 1. Improved Furnace Control : System identification and model predicative control of Outokumpu’s reheating furnace

   University essay from Uppsala universitet/Signaler och system

   Author : Oscar Holmqvist; [2023]
   Keywords : Systeem Identification; Model Predictive Control;

   Abstract : This thesis investigates one option for improving the control of a reheating furnace used in heating steel slabs before hot rolling; an essential part of the steel manufacturing process. The furnace consumes a significant amount of energy, leading to high cost and high carbon dioxide emissions. READ MORE

3. 2. Optimization of Material Cost and Carbon Footprint of Flat Reinforced Concrete Slabs with Simple Steel Piles : Designed according to Eurocode and Swedish appendix EKS

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Oskar Lönn; [2023]
   Keywords : Optimization; RC slab; Material cost; API;

   Abstract : When designing reinforced concrete (RC) slabs with steel piles various variables must be considered, from the internal force to the distance of piles. An endless number of designs are possible, leaving space for optimizing designs. READ MORE

4. 3. Macrosegregation Prediction in Continuously Cast Steel Slabs

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Malek Al-Ameri; [2022]
   Keywords : ;

   Abstract : A prediction model [3] of macrosegregation in continuously cast steel slabs developed by Barber et al from Corus Teesside Technology Centre, UK as an extension of the work of Miyazawa and Schwerdtfeger [4] is presented in this thesis. Improvements have been made in the model to include the effect of many bulges between the supporting rolls induced by the ferrostatic pressure exerted on the solidifying shell by the liquid phase, which were approximated following a deflection of an elastic beam model.

5. 4. Structural strengthening and sustainability improvements of existing buildings – A case study

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Pardis Niknafs; [2022]
   Keywords : Building retrofit; structural strengthening; energy efficiency; environmental impact; integrated and sustainable intervention; cross-laminated timber; life cycle assessment;

   Abstract : In Sweden, a large share of residential buildings was built more than 50 years ago. Consequently, old materials, poor maintenance, and corrosion can affect the structural performance of these buildings. Additionally, these buildings do not meet the latest energy efficiency and Eurocode regulations. READ MORE

6. 5. Concrete reinforced with FRP rebars : Evaluation of durability and behaviour in the Service Limit State (SLS)

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : David Ottosson; [2021]
   Keywords : GFRP; Durability; SLS; Atena;

   Abstract : One of the most common building materials is concrete and it has been for a long time. To overcome its low tensile capacity concrete structures are normally reinforced with steel rebars. READ MORE
