Texte intégralThis work deals with the simulation of virtual acoustic spaces using physics-based models. The acoustic space is what we perceive about space using our auditory system. The physical nature of the models means that they will present spatial attributes (such as, for example, shape and size) as a salient feature of their structure, in a way that space will be directly represented and manipulated by means of them.

Natural organisms evolved gene networks that measure continuous environmental information and adjust gene expression to maximize fitness. Engineered cells will need to be capable of similar signal processing and computation in order to operate efficaciously in complex environments, like the human body. In this thesis I describe the development of synthetic biological circuits that enable such capabilities. In the first chapter, analog gene networks are engineered to measure the concentration of molecules and to perform mathematical operations such as addition and division. Building on this work, analog gene networks are next engineered to compensate for input-sensor circuit crosstalk. Finally, in the third chapter, analog-to-digital converters are introduced to convert signals from analog gene circuits into discrete regimes of gene expression. This mixed-signal approach merges the benefits of analog signal processing and of digital signal integration to enable robust continuous signal processing. I posit that the computational architecture demonstrated herein will enable novel applications for the field of synthetic biology.

Texte intégralIncludes bibliographical references (p. 135-148).
In this thesis, techniques for high-precision synthesis of optical and microwave signals and their distribution to remote locations are presented. The first topic is ultrafast optical pulse synthesis by coherent superposition of mode-locked lasers. Timing and phase synchronization of ultrabroadband Ti:sapphire and Cr:forsterite mode-locked lasers is studied. Subfemtosecond (<0.4 fs) timing synchronization over 12 h is demonstrated. In addition to the timing lock, phase synchronization to a local oscillator with subfemtosecond accuracy (<0.5 fs) over 1000 s is achieved. Drift-free subfemtosecond timing and phase synchronization enables a phase-coherent spectrum over 1.5 octaves that has a potential to generate single-cycle optical pulses at 1 pm. The second topic is long-term stable microwave signal synthesis from mode-locked lasers. Although mode-locked lasers can produce ultralow-noise microwave signals as a form of optical pulse trains, the transfer of stability from optical to electronic domain is a highly non-trivial task. To overcome the limitations of conventional photodetection, an optoelectronic phase-locked loop based on electro-optic sampling with a differentially-biased Sagnac-loop is proposed. Long-term (>1 h) 3-mrad level phase stability of a 10.225 GHz microwave signal extracted from a mode-locked laser is demonstrated. The third topic is timing stabilized fiber links for large-scale timing distribution. Precise optical timing distribution to remote locations can result in synchronization over long distances. In doing so, acoustic noise and thermal drifts introduced to the fiber links must be canceled by a length-correction feedback loop. A single type-II phase-matched PPKTP crystal is used to construct a compact and self-aligned balanced optical cross-correlator for precise timing detection.
(cont.) Using this correlator, a 310 m long fiber link is stabilized with long-term sub-10 fs accuracy. The final topic is photonic analog-to-digital conversion of high-frequency microwave signals. Sampling of high-frequency (>10 GHz) microwave signals is challenging due to the required aperture jitter below 100 fs. An optical subsampling down- converter for analog-to-digital conversion of narrowband high-frequency microwave signals is studied. The measured signal to noise-and-distortion ratio of 1-Mbps signals at 9.5 GHz carrier frequency is 22 dB over 2 MHz bandwidth. By integrating the demonstrated techniques, large-scale femtosecond-precision timing distribution and synchronization systems can be implemented.

Texte intégralNonstationarity characterizes transient physical phenomena. For example, it may be caused by a speed variation of an accelerating engine. Similarly, because of the Doppler effect, a stationary sound emitted by a moving source is perceived as being nonstationary by a motionless observer. These examples lead us to consider a class of nonstationary signals formed from stationary signals whose stationarity has been broken by a physically relevant deformation operator. After describing the considered deformation models (chapter 1), we present different methods that extend the spectral analysis and synthesis to such signals. The spectral estimation amounts to determining simultaneously the spectrum of the underlying stationary process and the deformation breaking its stationarity. To this end, we consider representations of the signal in which this deformation is characterized by a simple operation. Thus, in chapter 2, we are interested in the analysis of locally deformed signals. The deformation describing these signals is simply expressed as a displacement of the wavelet coefficients in the time-scale domain. We take advantage of this property to develop a method for the estimation of these displacements. Then, we propose an instantaneous spectrum estimation algorithm, named JEFAS. In chapter 3, we extend this spectral analysis to multi-sensor signals where the deformation operator takes a matrix form. This is a doubly nonstationary blind source separation problem. In chapter 4, we propose a synthesis approach to study locally deformed signals. Finally, in chapter 5, we construct a time-frequency representation adapted to the description of locally harmonic signals

Texte intégralThis work belongs to the field of performative control of voice synthesis, and more precisely of real-time modification of pre-recorded voice signals. In a context where such systems were only capable of modifying parameters such as pitch, duration and voice quality, our work was carried around the question of performative modification of voice rhythm. One significant part of this thesis has been devoted to the development of Vokinesis, a program for performative modification of pre-recorded voice. It has been developed under 4 goals: to allow for voice rhythm control, to obtain a modular system, usable in public performances situations as well as for research applications. To achieve this development, a reflexion about the nature of voice rhythm and how it should be controlled has been carried out. It appeared that the basic inter-linguistic rhtyhmic unit is syllable-sized, but that syllabification rules are too language-dependant to provide a invariant inter-linguistic rhythmic pattern. We showed that accurate and expressive sequencing of vocal rhythm is performed by controlling the timing of two phases, which together form a rhythmic group: the rhythmic nucleus and the rhythmic link. We developed several rhythm control methods, tested with several control interfaces. An objective evaluation showed that one of our methods allows for very accurate control of rhythm. New strategies for voice pitch and quality control with a graphic tablet have been established. A reflexion about the pertinence of graphic tablets for pitch control, regarding the rise of new continuous musical interfaces, lead us to the conclusion that they best fit intonation control (speech), but that PMC (Polyphonic Multidimensional controllers) are better for melodic control (singing, or other instruments).The development of Vokinesis also required the implementation of the VoPTiQ (Voice Pitch, Time and Quality modification) signal processing method, which combines an adaptation of the RT-PSOLA algorithm and some specific filtering techniques for voice quality modulations. The use of Vokinesis as a musical instrument has been successfully evaluated in public representations of the Chorus Digitalis ensemble, for various singing styles (from pop to contemporary music). Its use for electro music has also been explored by interfacing the Ableton Live composition environnment with Vokinesis. Application perspectives are diverse: scientific studies (research in prosody, expressive speech, neurosciences), sound and music production, language learning and teaching, speech therapies
