  1. 1. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    University essay from KTH/Betongbyggnad

    Author : Mohammad Mustafa Angar; [2020]
    Keywords : Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Abstract : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. READ MORE

  2. 2. Carbon capture from reheating furnaces in the Swedish steel industry : evaluation of techno-economic feasibility

    University essay from Luleå tekniska universitet/Energivetenskap

    Author : Anna Haglund; [2020]
    Keywords : Carbon capture; CCS; Swedish steel indusrty; post-combustion;

    Abstract : The reduction of greenhouse gas emissions is important to keep climate change under control. One of the largest CO2 emitters of the Swedish industries is the steel industry. This is, among others, due to the need of heat treatments and reheating processes depending on high temperatures and fossil fuels. READ MORE

  3. 3. Adaptive Trajectory Tracking Control of a UAV using Gaussian Processes

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Philipp Rothenhäusler; [2020]
    Keywords : ;

    Abstract : Unmanned aerial vehicles are a popular choice for various transport and monitoringapplications. In many outdoor applications frequent variations of thevehicle conguration and time-varying disturbances originating from the environmentare expected. READ MORE

  4. 4. Optimal Control Model for an Autonomous Underwater Vehicle

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Gustav Holm; [2020]
    Keywords : ;

    Abstract : The main goal with this thesis was to develop an optimal control model for anautonomous underwater vehicle (AUV) and evaluate whether reference trackingusing Model Predictive Control (MPC) based on a linear dynamics modeldescribing all six degrees of freedom (DOF) is a suitable method for waypointnavigation. MPC is an advanced receding horizon optimal control method capableof including constraints in the optimization. READ MORE

  5. 5. Reinforced Concrete Structures Subjected to Imposed Deformations: A Study of Cracking due to Shrinkage in Slab Foundations for Residential Houses

    University essay from Lunds universitet/Avdelningen för Konstruktionsteknik; Lunds universitet/Institutionen för bygg- och miljöteknologi

    Author : Henrik Johansson; Martin Heinegård; [2020]
    Keywords : Reinforced concrete structures; nonlinear finite element analysis; crack widths; imposed deformations; shrinkage; foundation slabs; fracture mechanics; Atena 2D; Technology and Engineering;

    Abstract : The need for limiting crack widths in reinforced concrete structures is due to durability, tightness towards gaseous and liquid substances, and for aesthetic reasons. Although concrete cracks at relatively low tensile stresses and can not be avoided, strategies for crack control can be adopted to meet the requirements. READ MORE
