  2. 1. Studies in the Conceptual Development of Mathematical Analysis

    Author : Kajsa Bråting; Anders Öberg; Hans Niels Jahnke; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; History of mathematics; conceptual development; mathematical analysis; Other mathematics; Övrig matematik; Mathematics; Matematik;

    Abstract : This dissertation deals with the development of mathematical concepts from a historical and didactical perspective. In particular, the development of concepts in mathematical analysis during the 19th century is considered. The thesis consists of a summary and three papers. In the first paper we investigate the Swedish mathematician E. READ MORE

  4. 2. Integral equations and function extension techniques for numerical solution of PDEs

    Author : Fredrik Fryklund; Anna-Karin Tornberg; Alex Barnett; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : Today many phenomena from science and engineering can be simulated accurately thanks to computational methods. Still, many challenges remain, one of them being close interface interactions when simulating e.g. the dynamics of a substance concentration in multiphase flows at the micro level. READ MORE

  5. 3. Optimization-Based Models for Measuring and Hedging Risk in Fixed Income Markets

    Author : Johan Hagenbjörk; Jörgen Blomvall; Ou Tang; Giorgio Consigli; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Finance; Fixed income; Interest rate risk; Credit risk; Risk management; Optimization; Mathematics;

    Abstract : The global fixed income market is an enormous financial market whose value by far exceeds that of the public stock markets. The interbank market consists of interest rate derivatives, whose primary purpose is to manage interest rate risk. READ MORE

  6. 4. Dynamic Optimization for Agent-Based Systems and Inverse Optimal Control

    Author : Yibei Li; Xiaoming Hu; Per Enqvist; Yishao Zhou; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Inverse optimal control; formation control; differential game; credit scoring; Mathematics; Matematik;

    Abstract : This dissertation is concerned with three problems within the field of optimization for agent--based systems. Firstly, the inverse optimal control problem is investigated for the single-agent system. Given a dynamic process, the goal is to recover the quadratic cost function from the observation of optimal control sequences. READ MORE

  7. 5. Intrinsic Formation and Macroscopic Intervention in Multi-agent Systems

    Author : Silun Zhang; Xiaoming Hu; Johan Karlsson; Jorge Goncalves; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Attitude control; agents and autonomous systems; distributed control; formation control; nonlinear systems; moment based modelling; large- scale systems; reduced order modeling; nonlinear system identification; Mathematics; Matematik;

    Abstract : In this dissertation, we study two problems within the field of the multi-agent systems theory. One is the formation control for multiple reducedattitudes, which are extensively utilized in many pointing applications and under-actuated scenarios for attitude maneuvers. READ MORE
