  2. 1. Controlling the Roll Responses of Volume Carriers

    Author : Carl-Johan Söder; Anders Rosén; Jan De Kat; KTH; []
    Keywords : PCTC; parametric roll; roll response; roll damping; rudder control; aerodynamic roll damping; roll mitigation; racking; Ikeda’s method; CFD; model tests; Full-scale tests; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : Modern volume carriers such as container vessels, cruise ships and Pure Car and Truck Carriers (PCTC’s) have become more vulnerable to critical roll responses as built in margins have been traded against increased transport efficiency. The research presented in this doctoral thesis aims at enhancing the predictability and control of these critical roll responses. READ MORE

  5. 3. Local and Piecewise Affine Approaches to System Identification

    Author : Jakob Roll; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Identification of nonlinear systems is a multifaceted research area, with many diverse approaches and methods. This thesis considers two different approaches: (nonparametric) local modelling, and identification of piecewise affine systems. READ MORE

  6. 4. Robust Verification and Identification of Piecewise Affine Systems

    Author : Jakob Roll; Lennart Ljung; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piecewise affine systems; Verification; Robustness; Identification; Mixed-integer programming;

    Abstract : iecewise affine systems constitute an important subclass of hybrid systems, and consist of several affine dynamic subsystems, between which switchings occur at different occasions. As for hybrid systems in general, there has been a growing interest for piecewise affine systems in recent years, and they occur in many application areas. READ MORE

  7. 5. The neurophysiology of grammatical constraints : ERP studies on the influence of prosody and pragmatics on the processing of syntax and morphology in Swedish

    Author : Mikael Roll; Allmän språkvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; linguistics; event-related potentials; ERP; pragmatics; language processing; prosody; syntax;

    Abstract : This dissertation investigates the interaction of information from word order, morphology, lexical semantics, and prosody in the on-line processing of Swedish sentences using Event-Related Potentials. Study I examines how the form, meaning, and syntactic position of objects influence their interpretation in ‘Object Shift’ contexts. READ MORE
