  2. 1. Corresponding States Correlations for the Prediction of Thermodynamic Properties of Refrigerants

    Author : Maria Sörner; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; refrigerant mixtures; corresponding states; parameter estimation; equation of state; refrigerants; thermodynamic properties;

    Abstract : When process equipment such as separation units, heat pumps, and refrigeration systems are simulated or designed, physico-chemical properties of the fluids involved must be known. The outcome of the simulation or design depends on the accuracy of the correlations used in the prediction of physico-chemical data, so it is of the utmost importance that the correlations used correctly describe the properties of the fluids.

  5. 3. Ferromagnetic Resonance as a Probe of Magnetization Dynamics : A Study of FeCo Thin Films and Trilayers

    Author : Yajun Wei; Peter Svedlindh; Sujeet Chaudhary; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ferromagnetic resonance FMR ; Gilbert damping; magnetic coupling; FeCo;

    Abstract : The high frequency dynamic magnetic responses of FeCo thin films and structures have been investigated mainly using ferromagnetic resonance (FMR) technique.The FMR resonance condition and linewidth are first derived from the dynamic Landau- Lifshitz-Gilbert equation, followed by a study of the conversion between FMR field and frequency linewidths.

  6. 4. The Dynamic Development of Cognitive and Socioemotional Traits and Their Effects on School Grades and Risk of Unemployment : A Test of the Investment Theory

    Author : Elias Johannesson; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Fluid intelligence Gf ; Crystallized intelligence Gc ; cognitive abilities; socioemotional traits; academic achievement; unemployment; discrete-time survival analysis;

    Abstract : The purpose of this thesis is to examine the dynamic development of cognitive and socioemotional traits and how these traits influence academic achievement and predict risk of unemployment. Data was retrieved from the Evaluation Through Following-up (ETF) database. READ MORE

  7. 5. Aspects of Wave Interaction in Nonlinear Media

    Author : Björn Hall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear Schrödinger equation; incoherent solitons; partial incoherence; nonlinear wave interaction; Gross-Pitaevskii equation; modulational instability; collective dynamics; Wigner transform; nonlinear guided waves; Bose-Einstein condensation;

    Abstract : Selected aspects of various types of nonlinear wave interaction are investigated. These aspects are studied in terms of models described by Nonlinear Schrödinger equations, mainly analytically and numerically, but also experimentally. READ MORE
