  1. 1. Price policy estimation for Demand Response of heat-pump-based loads

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Carlos Eduardo Gil Simancas; [2023]
    Keywords : Differential Evolution; Electricity Grids; Flexibility Services; Heat-pumps; Heterogeneous Loads; Implicit Demand Response; Optimization; Differentiell utveckling; elnät; flexibilitetstjänster; heterogena belastningar; implicit efterfrågesvar; optimering; värmepump;

    Abstract : The electricity grids have become a key player in the society. An increased usage of electricity is both a result from the more electrified society, but also as a main solver in reaching the climate goals by reducing emissions. READ MORE

  3. 2. Short-horizon Prediction of Indoor Temperature using Low-Order Thermal Networks : A case study of thermal models for heat-system control applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Jonas Cederberg; [2023]
    Keywords : Lumped Parameter Thermal Network; Resistance-Capacitance model; Parameter estimation; Modelling of Dynamical Systems; Thermal modelling; Temperature Prediction; Termiskt nätverk med klumpade parametrar; Mostånds-kapacitans modell; Parameterestimering; Modellering av dynamiska system; Termisk modellering; Temperaturprediktion.;

    Abstract : Optimizing and controlling the heating systems in buildings is one way to decrease their load on the power grid, as well as introduce load flexibility to be used in Demand Response (DR) applications. A requirement in occupied buildings is that the thermal comfort of the residents is guaranteed, making the optimization of heating systems a constrained problem with respect to indoor temperature.

  4. 3. Investigating and Fabricating High-K (Al2O3) and Ferroelectric (HfO2) MIM-Capacitors for use in BEOL Fabrication Applications

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Thomas Hackett; [2021]
    Keywords : atomic layer deposition ALD ; ferroelectric; metal-insulator-metal MIM capacitors; low thermal budget; rapid thermal annealing RTA ;

    Abstract : Integration of high-K Metal-Insulator-Metal (MIM) capacitors in the Back-end-of-line (BEOL) is a topic of interest for the further development of the process at KTH Royal Institute of Technology. MIM-capacitors benefit from having constant capacitance values over a range of voltages and/or frequencies. READ MORE

  5. 4. Ferroelectricity in nanocrystalline Hf0.5Zr0.5O2 thin films

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Lun Sang; [2018]
    Keywords : ferroelectricity; Hf0.5Zr0.5O2; GIXRD; XRR; Technology and Engineering; Physics and Astronomy;

    Abstract : Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. READ MORE

  6. 5. Optimization of through-silicon via structures in a fingerprint sensor package

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Gustaf Onsbring Gustafson; [2017]
    Keywords : Through-silicon via; Fingerprint sensor; Semiconductor package; Technology and Engineering;

    Abstract : The through-silicon via (TSV) is a type of vertical electrical connection that can pass through a silicon wafer or die. By using TSVs, compared to using wire bonding as interconnections in a capacitive fingerprint sensor, the capacitive strength between the sensor die and the finger can be increased. READ MORE
