  1. 16. Organic and organometallic compounds for nonlinear absorption of light

    Författare :Per Lind; Bertil Eliasson; Adolf Gogoll; Umeå universitet; []
    Nyckelord :Organic chemistry; Nonlinear absorption; thiophene; platinum complexes; optical limiting; sonogashira coupling reactions; molecular orbital calculations; Organisk kemi; organisk kemi; Organic Chemistry;

    Sammanfattning : The demand for protection of eyes and various types of optical sensors from laser-beam pulses has resulted in the search for optical limiting devices that have the property of being transparent at low intensity of light (normal light), but non-transparent towards high intensity (laser) light. This type of protection may be obtained by using an organic material that displays nonlinear optical (NLO) properties. LÄS MER

  2. 17. Development of Separation Phenomena on a Passenger Car

    Författare :Sabine Bonitz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; complex flows; vortex formation; vehicle aerodynamics; flow separation; limiting streamlines; crossflow separation;

    Sammanfattning : The general shape of a vehicle influences its aerodynamic performance through separation phenomena and flow structure development. Since these flow characteristics have a direct influence on the energy efficiency, safety and comfort, it is essential to study their formation and evolution into the freestream. LÄS MER

  3. 18. Weighted inequalities involving Hardy-type and limiting geometric mean operators

    Författare :Maria Nassyrova; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis consists of an introduction and five papers, which all are devoted to different questions connected to weighted Hardy-type inequalities and their generalizations. The introduction gives an elementary overview of the area and serves as a frame for the following papers. In particular, it is pointed out where the obtained results fit in. LÄS MER

  4. 19. On the fluid mechanics of electrochemical coating and spray painting

    Författare :Pedro Olivas; KTH; []
    Nyckelord :mass transfer; electrochemical coating; ion transport; forced convection; diffusion; magnetoelectrolysis; electrolyte; limiting current; numerical simulation;

    Sammanfattning : Finite-volume methods have been used for modeling of fluidflows involved in forced convection electrochemical coating androtating spray painting systems. Electrodeposition on a singlecircular cylinder under forced convection for Reynolds numbers10 and 200 was simulated. LÄS MER
