  2. 11. Application-Oriented Input Design and Optimization Methods Involving ADMM

    Author : Mariette Annergren; Bo Wahlberg; Håkan Hjalmarsson; Lieven Vandenberghe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis is divided into two main parts. The first part considers application-oriented input design, specifically for model predictive control (MPC). The second part considers alternating direction method of multipliers (ADMM) for ℓ1 regularized optimization problems and primal-dual interior-point methods. READ MORE

  4. 12. Dilute Nitride Lasers and Spectrally Engineered Semiconductor Laser Resonators

    Author : Göran Adolfsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; single mode laser; transfer matrix method; threshold current; InGaAs; GaAs; multiple quantum wells; dilute nitrides; two-color laser; GaInNAs; Semiconductor lasers; molecular beam epitaxy; characteristic temperature; temperature dependence; ambipolar diusion; Fabry-Perot resonator; spectral engineering;

    Abstract : The first part of this thesis deals with long wavelength (1.2-1.3 um) InGaAs(N)multiple quantum-well (QW) lasers grown on GaAs, with the aim of understandingand improving their threshold and temperature characteristics. The epitaxialmaterial is grown by molecular beam epitaxy (MBE). READ MORE

  5. 13. SEMANTIC INFORMATION AND PHYSICAL MULTI-DOMAIN MODELING AND SIMULATION FOR POWER SYSTEMS

    Author : Francisco José Gómez; Luigi Vanfretti; Svein Olsen; Peter Palensky; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; POWER SYSTEMS; MODELING; SIMULATION; CIM; MODELICA; ISO 15926; MULTI-DOMAIN; UML; SYSML; Energy Technology; Energiteknik;

    Abstract : There are different reasons for combining different modeling languages and simulationlanguages: Exchange of more detailed information about power network components, theirparameters and, most importantly, mathematical equations describing their behavior andthe exchange of a mathematical description, using equation-based languages (e.g. READ MORE

  6. 14. Novel Processing and Electrical Characterization of Nanowires

    Author : Kristian Storm; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gate; Capacitance; Hall effect; InP; InAs; Characterization; Nanowires; Processing; LED; Transistor; Fysicumarkivet A:2013:Storm;

    Abstract : This thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. READ MORE

  7. 15. Analog Circuit Topology Development: Practice methods for technology and teaching based on comprehensible transistor models

    Author : Roger Malmberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; episteme; analog design; circuit synthesis; field-effect transistor; teaching method; phronesis; techne; bipolar transistor; transistor model;

    Abstract : To obtain adequate knowledge for design of robust analog circuits in industry, circuit engineers gain main knowledge from own practice experience, because theory taught by universities rarely states validity limits and result spreads. Therefore, when going from university to industry, the engineers find this theory nontrustworthy and relinquish it. READ MORE
