  2. 1. An Embodied Account of Action Prediction

    Author : Claudia Elsner; Gustaf Gredebäck; Claes von Hofsten; Amanda L. Woodward; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Action prediction; biological motion; direct-matching; embodied simulation; eye movements; eye-tracking; give-me gesture; mirror neuron; motor cortex; point-light; social interaction; TMS; Psychology; Psykologi;

    Abstract : Being able to generate predictions about what is going to happen next while observing other people’s actions plays a crucial role in our daily lives. Different theoretical explanations for the underlying processes of humans’ action prediction abilities have been suggested. READ MORE

  4. 2. Direct Extraction of MOS Transistor Current Model Parameters

    Author : Peter R. Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis presents a study of MOS transistor model parameter extraction. The objective of this study was to develop an efficient, accurate, robust extraction strategy which determines physically reasonable parameter values. The direct parameter extraction approach was chosen to meet these requirements. READ MORE

  5. 3. Zero and Multi-Dimensional Modeling of Internal Combustion Engines with respect to Ion Current and Soot Formation

    Author : Abdelhadi Ahmedi; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine knock; pollutant emissions; detailed chemical kinetics; thermal ionization.; ion current sensor; method of moments; ionization; soot formation oxidation; modeling; auto-ignition; Spark ignition engine; diesel engine;

    Abstract : The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. READ MORE

  6. 4. On methods of measuring magnetic properties of power transformers

    Author : Claes Carrander; Göran Engdahl; Anders Bergqvist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; No-load; magnetizing current; losses; diagnostics; delta; three-phase; power transformer; magnetic core; electrical steel; measurements; simulation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The core of a power transformer can weigh hundreds of tons, and represents a significant part of the total ownership cost of the transformer, in terms of both the construction cost and of the monetary cost of losses. It is therefore desirable to have a method of diagnosing the core to ensure optimal performance, and to enable the operator to plan repairs of damaged or defective cores. READ MORE

  7. 5. Charge and Energy Noise from On-demand Electron Sources

    Author : Nastaran Dashti; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Boltzmann-Langevin approach.; fluctua- tions and noise; single-electron source; energy and heat currents; time-dependently driven mesoscopic capaci- tor; charge current; Floquet scattering theory;

    Abstract : On-demand single electron sources (SES) are of key importance for future electronic applications such as metrology or quantum optics with electron. They allow for achieving a controlled, low-fluctuations flow of particles in a coherent mesoscopic conductor. READ MORE
