  2. 1. Non-selfadjoint operator functions

    Author : Axel Torshage; Christian Engström; Marco Marletta; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Non-linear spectral problem; numerical range; pseudospectrum; resolvent estimate; equivalence after extension; block operator matrices; operator functions; operator pencil; spectral divisor; joint numerical range; Mathematics; matematik;

    Abstract : Spectral properties of linear operators and operator functions can be used to analyze models in nature. When dispersion and damping are taken into account, the dependence of the spectral parameter is in general non-linear and the operators are not selfadjoint. READ MORE

  4. 2. Quantifying Operability of Working Machines

    Author : Reno Filla; Jan-Ove Palmberg; Kjell Ohlsson; Jonas Larsson; Linköpings universitet; []
    Keywords : Operability; machine harmony; operator workload; control effort; simulation; operator model; human operator; working machines; construction equipment; wheel loaders; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In working machines the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. READ MORE

  5. 3. Integrable Systems and Operator Equations

    Author : Cornelia Schiebold; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; integrable systems; operator equations; asymptotics of solutions; MATHEMATICS; MATEMATIK;

  6. 4. Laser on kinetic operator

    Author : Håkan Fredriksson; Ivan Kalaykov; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : This thesis highlights a variety of aspects within the field of mobile robots. The hinge is system architecture for mobile robots. For a mobile robot to be put into operation all necessary systems have to be functioning and control mechanisms have to be established. The robot may be set to operate autonomously as well as remotely controlled. READ MORE
