  2. 16. Bipolar Transistor Parameter Extraction, Modeling and Test Structure Design

    Author : Fredrik Ingvarson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis, techniques are presented for determining the model parameter values required by compact bipolar transistor models in circuit simulators. Specifically, extraction of the Early voltages and the transistor series resistances are treated in detail. Extraction of other compact model parameters is also covered. READ MORE

  4. 17. Modeling and Model-based Control of Automotive Air Paths

    Author : Robin Holmbom; Lars Eriksson; Daniel Jung; Christopher Onder; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The strive towards cleaner and more efficient combustion engines, driven by legislation and cost, introduces new configurations, as exhaust gas recirculation, turbocharging, and variable valve timing, to name a few. Beside all the positive effects on the emissions and fuel consumption, they all affect the air-charge system, which increases the cross-couplings within the air-path control, making it an even more complex system to control.

  5. 18. Electromagnetic modeling using the partial element equivalent circuit method

    Author : Jonas Ekman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : This thesis presents contributions within the field of numerical simulations of electromagnetic properties using the Partial Element Equivalent Circuit (PEEC) method. Numerical simulations of electromagnetic properties are of high industrial interest. READ MORE

  6. 19. Stellar Models in General Relativity

    Author : Lars Samuelsson; Kjell Rosquist; Brandon Carter; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; General relativity; compact objects; neutron stars; Physics; Fysik;

    Abstract : Neutron stars are some of the most fascinating objects in Nature. Essentially all aspects of physics seems to be represented inside them. Their cores are likely to contain deconfined quarks, hyperons and other exotic phases of matter in which the strong interaction is the dominant force. READ MORE

  7. 20. Multi-objective CFD-based design method for axial compressors

    Author : Lars R Ellbrant; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Q3D; Turbomachinery; Design; Meta-modeling; Optimization; CFD; Validation; Compressor; Transonic;

    Abstract : Economic aspects such as reducing specific fuel consumption and ever growing environmental requirements on emissions and perceived noise levels are the major incentives in the pursuit to improve aircraft engines. The overall efficiency of the engine is a combination of propulsive efficiency and thermal efficiency. READ MORE
