L'impressionismo di Octave Mirbeau: un'estetica del fluido
… da un fermento di idee, situiamo la figura di Octave Mirbeau, critico d arte, romanziere, drammaturgo, saggista, del quale evidenziamo lo stretto legame tra le sue idee in ambito artistico e la sua poetica. Dopo un rapido schizzo della storia della critica d arte ed una panoramica della …

Octave-spanning lasers for optical metrology applications
This thesis describes the first octave-spanning frequency comb based on a prismless, Ti:sapphire laser. It covers in detail the design and construction of the laser system, as well as the electronic stabilization scheme used to control the frequencies of the mode comb. The system developed is …

Dans les affres de la création: la double figure de l'artiste dans le roman Dans le ciel d'Octave Mirbeau
… de la fin du XIXe siècle : Dans le ciel d'Octave Mirbeau. Écrit au fil de la plume, ce roman est paru pour la première fois dans le quotidien L'Écho de Paris de 1892 à 1893, mais n'a été publié en volume qu'une centaine d'années plus tard. Dans le ciel décrit la déchéance …

Living French colonial theory : an examination of France's complex relationship with Islam in its African colonies as viewed through the lives of Octave Houdas and Xavier Coppolani
… of the lives of two colonial figures, Octave Houdas and Xavier Coppolani. Both men were prominent Islamists with career trajectories deeply steeped within Orientalist rhetoric in the late nineteenth-century and with strong ties to Algeria. However, a detailed and comprehensive …

Design and Analysis of Star Spiral with Application to Wideband Arrays with Variable Element Sizes
… with variable element sizes (WAVES) is a multi-octave array that uses different sized circular Archimedean spirals for each octave of frequency coverage. A two-octave WAVES array has been presented in the literature, but a gap in the two-octave frequency coverage exists along the principal axes. …

Anomaly detection for environmental noise monitoring
Octave-band sound pressure level is the preferred measure for continuous environmental noise monitoring over raw audio because accepted standards and devices exist, these data do not compromise voice privacy, and thus an octave-band sound meter can legally collect data in public. By setting up an …

Creating an Accessible Microtonal System
… system with an alternate division of the octave that includes all the necessary material such that a performer or composer could utilize this system efficiently and intuitively. For the purposes of this project, the system will be applied to the cello, as its rich timbre and continuous …

Neural correlates of pitch and roughness : toward the neural code for melody and harmony
… universality of many aspects of music, such as octave-based tuning systems and the use of dissonance and consonance to create harmonic tension and resolution, suggests that their perception may have fundamental neurophysiological bases. Thus, music provides a natural set of stimuli and …

The Well Tempered Building; A Music Conservatory
… move to different keys within a composition. The Octave is the most significant key signature because it completes the circle of fifths. The Octave, if in perfect tune will create an overtone, which is a tune unable to be created on its own. The movement through the Circle of Fifths led to a …

Broadband RF Power Amplifier Design Methodology Using Sequential Harmonic Characterization
… In this thesis, a design methodology for multi-octave RF power amplifiers is presented based on the proposed sequential harmonic characterization. Compared to the conventional method, a more optimal performance is achieved using the proposed technique. To validate the proposed method, a …

Synthesis, design, and fabrication techniques for reconfigurable microwave and millimeter-wave filters
… up to 90% reduction of bandwidth variation in octave-tunable bandstop filters.</p> <p>Lastly, a new differential coupling structure for evanescent-mode cavity resonators is developed, enabling the design of fully-balanced and balanced-to-unbalanced (balun) filters. An octave-tunable 3-pole …

Source activity and tonotopic organization of the auditory cortex in musicians and non-musicians
… (the lower frequencies more superficial, 2.3 mm/octave), the late activity at 100 ms a mirror-imaged tonotopic map (the higher frequencies more superficial, 1.45 mm/octave) in the planum temporale. A correlation with the music aptitude was not found.

Second Harmonic Generation in Silicon Photonic Crystal Resonators for Quantum Optic Applications
… cavities. A silicon architecture that has octave-separated resonances with high quality factor, low mode volume, high nonlinear coupling is implemented in the form of a one dimensional photonic crystal nanobeam cavity for efficient second harmonic generation.

Long-Term Ambient Noise Statistics in the Gulf of Mexico
… of 10-1000 Hz. Data are processed in eight 1/3-octave frequency bands, centered from 25 to 950 Hz, and monthly values of the following statistical quantities are computed from the resulting eight time series of noise spectral level: mean, median, standard deviation, skewness, kurtosis and …

High-energy sub-cycle optical waveform synthesizer
… which requires a fully phase-controlled multiple-octave-spanning spectrum. To date, no single laser source can support a bandwidth of more than an octave. Coherent synthesis of pulses with different spectra, or wavelength multiplexing, presents a route towards obtaining a multi-octave spanning …

Investigation of physical and psychophysical methods for the attenuation measurement of circumaural hearing protectors with implication for field use
… alternative measures were made across nine 113 octave bands centered at 125, 250, 500, 1000, 2000, 3150,4000, 6300, and 8000 Hz. The experiment also explored a means for predicting broadband attenuation from data of a single 113 octave band through a regression analysis for both PT -REAT tests …
