    Sammanfattning : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

  3. 17. SiC CMOS and memory devices for high-temperature integrated circuits

    Författare :Mattias Ekström; Carl-Mikael Zetterling; B. Gunnar Malm; Tobias Erlbacher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bismuth titanate Bi4Ti3O12 ; CMOS; ferroelectric capacitor; field oxide; inverter; metallisation; metal oxide semiconductor field effect transistor MOSFET ; ohmic contacts; ring oscillator; semiconductor processing; silicon carbide 4H-SiC ; CMOS; ferroelektrisk kondensator; fältoxid; halvledartillverkning; inverterare; kiselkarbid 4H-SiC ; metallisering; MOSFET; ohmska kontakter; ringoscillator; vismuttitanat Bi4Ti3O12 ; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : High-temperature electronics find use in extreme environments, like data logging in downhole drilling for geothermal energy production, inside of high-temperature turbines, industrial gas sensors and space electronics. The simplest systems use a sensor and a transmitter, but more advance electronic systems would additionally require a microcontroller with memory. LÄS MER

  4. 18. Sparse Modeling Heuristics for Parameter Estimation - Applications in Statistical Signal Processing

    Författare :Stefan Ingi Adalbjörnsson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parameter estimation; sparse models; convex optimization; fundamental frequency; inharmonicity; audio localization; symbolic periodicity; alternating directions method of multipliers; N-dimensional decaying sinusoids.;

    Sammanfattning : This thesis examines sparse statistical modeling on a range of applications in audio modeling, audio localizations, DNA sequencing, and spectroscopy. In the examined cases, the resulting estimation problems are computationally cumbersome, both as one often suffers from a lack of model order knowledge for this form of problems, but also due to the high dimensionality of the parameter spaces, which typically also yield optimization problems with numerous local minima.
