  4. 13. Microwave Transistor Noise Model Extraction Methods and a Non-Contacting Scattering Parameter Measurement Method

    Författare :Jörgen Stenarson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extraction; S-parameter; noise parameter; vector network analyzer; electro-magnetic probe; microwave; non-contacting testing; transistor noise model; VNA; EM-probe; non-invasive testing;

    Sammanfattning : This thesis has two parts. The first part discuss noise model extraction methods for FETs. The second part describe theory and implementation of a non-contacting S-parameter measurement method. Noise is an important aspect for a circuit designer, because noise generated in the circuit is a sensitivity limiting factor. LÄS MER

  5. 14. Spelling Normalisation and Linguistic Analysis of Historical Text for Information Extraction

    Författare :Eva Pettersson; Joakim Nivre; Beáta Megyesi; Michael Piotrowski; Uppsala universitet; []
    Nyckelord :NLP for historical text; spelling normalisation; digital humanities; information extraction; character-based statistical machine translation; SMT; Levenshtein edit distance; language technology; computational linguistics; Computational Linguistics; Datorlingvistik;

    Sammanfattning : Historical text constitutes a rich source of information for historians and other researchers in humanities. Many texts are however not available in an electronic format, and even if they are, there is a lack of NLP tools designed to handle historical text. LÄS MER

  7. 15. Feature Extraction for Low-Frequency Signal Classification

    Författare :José Chilo; Thomas Lindblad; Christian Bohm; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; infrasound; seismic signals; feature extraction; wavelets; fingerprints; mining; multimodal data space; Atomic physics; Atomfysik; Electronics;

    Sammanfattning : The development of the International Monitoring System (IMS) for the verification of the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has led to a rapid revival of interest in infrasound. Furthermore, the installation of low-frequency sensors at seismic sites has increased in recent years, providing researchers with large and heterogeneous data-sets in near real-time. LÄS MER
