    Sammanfattning : The aim of a text-to-speech synthesis (TTS) system is to generate a human-like speech waveform from a given input text. Current TTS sys- tems have already reached a high degree of intelligibility, and they can be readily used to read aloud a given text. For many applications, e.g. LÄS MER

  3. 2. Robust Transceiver Design and Waveform Synthesis for Wideband MIMO Radar

    Författare :Marie Ström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wideband radar; Robust analysis; Interference; Waveform synthesis; Transmit–receive filter design; MIMO radar;

    Sammanfattning : This thesis deals with the problem of designing and synthesizing waveforms that are optimal, both in a signal-to-noise-and-interference ratio (SNIR), and in a system hardware design perspective, i.e., to synthesize time domain waveforms with a low peak-to-average power ratio (PAPR), or even constant modulus.

  4. 3. Electrothermal Simulation in a Concurrent Waveform Relaxation Based Circuit Simulator

    Författare :Magnus Wiklund; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit synthesis; Bond graphs; Nullor; Circuit theory; Analog simulation; Circuit simulation; Multiprocessor computer; CONCISE; Parallel computation; Waveform relaxation; Thermal models; Transistor models; Electro-thermal simulation; Electro-thermal modeling; Translinear circuits; Electronics; Elektronik; Electrical engineering; Elektroteknik;

    Sammanfattning : The main purpose of this work is to study methods to simulate electro-thermal effects in integrated circuits using CONCISE a waveform relaxation based circuit simulator. WR is a method that is suitable to run on a multi-computer with state of the art computing power. Especially CMOS VLSI circuits have been simulated successfully with WR. LÄS MER

  5. 4. A Solution Exchange Platform for Exposure of Cells to Chemical Waves

    Författare :Jessica Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; waveform synthesis; solution exchange; cell signalling; patch clamp; receptor; high through-put; microfluidics; microfabrication; channel; chemical oscillations; ion channel; poly dimethylsiloxane ; drug discovery;

    Sammanfattning : This thesis presents the development, characterization and suggested applications of a platform for controlling the chemical environment around a cell or a cell constituent. The platform is unique in its capability to combine rapid solution switching with precise timing and access to a manifold of solution environments. LÄS MER

  7. 5. On Prosodic Modification of Speech

    Författare :Barbara Resch; Bastiaan Kleijn; Thomas Eriksson; KTH; []
    Nyckelord :;

    Sammanfattning : Prosodic modification has become of major theoretical and practical interest in the field of speech processing research over the last decades. Algorithms for time and pitch scaling are used both for speech modification and for speech synthesis. LÄS MER
