  1. 1. Real-Time Control Systems with Delays

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Johan Nilsson; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timing jitter; Stochastic parameters; Stochastic control; Real-time systems; Linear quadratic control; Jump linear systems; Distributed computer control systems; Clock synchronization; Delay compensation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : Control loops that are closed over a communication network get more and more common. A problem with such systems is that the transfer delays will be varying with different characteristics depending on the network hardware and software. READ MORE

  2. 2. State Estimation for Distributed and Hybrid Systems

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Peter Alriksson; Lunds universitet.; Lund University.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Joint Maximum a Posteriori Estimation; Sensor Networks; Distributed State Estimation; Networked Embedded Systems; Markov Jump Linear Systems; Sensor Scheduling;

    Abstract : This thesis deals with two aspects of recursive state estimation: distributed estimation and estimation for hybrid systems. In the first part, an approximate distributed Kalman filter is developed. Nodes update their state estimates by linearly combining local measurements and estimates from their neighbors. READ MORE

  3. 3. Structural Changes in Nonionic Surfactant Systems

    University dissertation from Lund University (Media-Tryck)

    Author : Sanja Bulut; Lunds universitet.; Lund University.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vesicles; Nonionic Surfactant; Wormlike Micelles; Lamellar Phase; NMR; MRI; SLS; DLS; cryo-fracture-TEM; centrifugation; cryo-TEM;

    Abstract : In this thesis we have studied structural changes of a nonionic surfactant self-assembly, as governed by changes in temperature and concentration. The techniques used in experimental investigations were dynamic and static light scattering, nuclear magnetic resonance and cryo-transmission electron microscopy (using a novel specimen preparation protocol).

  4. 4. Investigations of Waterjet/Hull Interaction Effects

    University dissertation from Lund University (Media-Tryck)

    Author : Arash Eslamdoost; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pressure jump method; thrust deduction; numerical simulation; waterjet propulsion; gross thrust; trim angle; waterjet hull interaction; net thrust; potential flow; sinkage; non-linear free-surface;

    Abstract : A waterjet propulsor operates in a different way than a conventional propeller. This makes it hard to use the same concepts for studying the thrust and powering of these systems. READ MORE

  5. 5. Concept evaluation and contact problems in simple rotordynamical systems

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Magnus Karlberg; Luleå tekniska universitet.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : Rotating machines serves an important role in many different applications. Extensive research has been made, manly during the last century, in order to develop these systems and understand the dynamics. The theory of rotordynamics differs in many fundamental aspects from structural dynamics and is therefore usually treated as an own research area. READ MORE
