Texte intégralNegli ultimi 50 anni il diametro dei principali telescopi a terra del mondo è più che raddoppiato, passando dai circa 5 m del telescopio Hale ai più di 10 m del telescopio Gran Telescopio Canarias, in risposta alle necessità del mondo astronomico nel suo tentativo di spingere sempre più lontano i confini della nostra conoscenza della volta celeste. La comunità astronomica è ora proiettata ed in attesa dell’era dei telescopi da 40 m, che permetteranno di migliorare le nostre conoscenze e la nostra comprensione in moltissimi campi astronomici, permettendo di osservare sorgenti sempre più deboli e lontane, spingendo il nostro sguardo oltre i limiti attuali, fino ai sfiorare i confini dell’Universo appena nato. Tuttavia, dal momento che i telescopi a terra sono affetti dal fenomeno naturale del seeing, dovuto alla presenza di un mezzo turbolento tra il telescopio e la volta celeste (l’atmosfera), anche il telescopio più grande diverrebbe equivalente, quantomeno in termini di risoluzione e qualità dell’immagine, a un telescopio di poche decine di centimetri se non si risolve il problema del seeing. Questo è esattamente il proposito dell’Ottica Adattiva, che gioca un ruolo chiave nelle osservazioni astronomiche da terra, dal momento che permette ai telescopi di riacquisire, totalmente o in parte a seconda della tecnica di Ottica Adattiva utilizzata, il loro limite di risoluzione teorico imposto dalla diffrazione. Data la sua importanza, negli ultimi decenni sono stati sviluppati molti sistemi e concetti di Ottica Adattiva, ognuno con le sue peculiarità e caratteristiche. LINC-NIRVANA, l’interferometro di Fizeau per il Large Binocular Telescope, è equipaggiato con un complesso modulo di Ottica Adattiva Multiconiugata (MCAO), che consente di correggere uniformemente un campo di vista di 2 arcmin, permettendo di ottenere immagini interferometriche su un campo di 10 x 10 arcsec, molto esteso se comparato ad altri interferometri, con una risoluzione equivalente a quella di un telescopio di 23 m. In sostanza, in questa configurazione, LBT può essere considerato un precursore degli ELTs. In questo Tesi darò una descrizione dettagliata del modulo MCAO equipaggiato a LINC-NIRVANA, concentrandomi in particolare sui due principali sottosistemi che lo costituiscono: il Ground layer Wavefront Sensor (GWS) e l’High layer Wavefront Sensor (HWS). Darò una panoramica dei concetti di ottica su cui si basano questi sensori, definirò le procedure di allineamento utilizzate per soddisfare le rigide tolleranze imposte per poter operare lo strumento con buone prestazioni e infine descriverò i risultati dell’allineamento e di verifica. Inoltre, descriverò le attività e i risultati ottenuti durante un Pathfinder Experiment, il cui scopo principale è stato sia verificare le prestazioni di uno dei due GWSs come un sistema a sé stante, comandando lo specchio secondario adattivo di LBT, sia le nostre capacità di renderlo possibile, acquisendo esperienza per il futuro commissioning di LINC-NIRVANA, previsto per la fine del 2016. Essendo LINC-NIRVANA una collaborazione Italia/Germania, le attività effettuate dallo scrivente e descritte in questa Tesi sono state svolte in Italia, Germania e USA (per il Pathfinder).

Texte intégralThe thesis is devoted to the solution of the actual scientific and practical problem in telecommunication systems, namely increasing the bandwidth of the semantic speech data transmission channel due to their efficient coding, that is the question of increasing the efficiency of semantic coding is formulated, namely – at what minimum speed it is possible to encode semantic features of speech signals with the set probability of their error-free recognition? It is on this question will be answered in this research, which is an urgent scientific and technical task given the growing trend of remote human interaction and robotic technology through speech, where the accurateness of this type of system directly depends on the effectiveness of semantic coding of speech signals. In the thesis the well-known method of increasing the efficiency of semantic coding of speech signals based on mel-frequency cepstral coefficients is investigated, which consists in finding the average values of the coefficients of the discrete cosine transformation of the prologarithmic energy of the spectrum of the discrete Fourier transform treated by a triangular filter in the mel-scale. The problem is that the presented method of semantic coding of speech signals based on mel-frequency cepstral coefficients does not meet the condition of adaptability, therefore the main scientific hypothesis of the study was formulated, which is that to increase the efficiency of semantic coding of speech signals is possible through the use of adaptive empirical wavelet transform followed by the use of Hilbert spectral analysis. Coding efficiency means a decrease in the rate of information transmission with a given probability of error-free recognition of semantic features of speech signals, which will significantly reduce the required passband, thereby increasing the bandwidth of the communication channel. In the process of proving the formulated scientific hypothesis of the study, the following results were obtained: 1) the first time the method of semantic coding of speech signals based on empirical wavelet transform is developed, which differs from existing methods by constructing a sets of adaptive bandpass wavelet-filters Meyer followed by the use of Hilbert spectral analysis for finding instantaneous amplitudes and frequencies of the functions of internal empirical modes, which will determine the semantic features of speech signals and increase the efficiency of their coding; 2) the first time it is proposed to use the method of adaptive empirical wavelet transform in problems of multiscale analysis and semantic coding of speech signals, which will increase the efficiency of spectral analysis due to the decomposition of high-frequency speech oscillations into its low-frequency components, namely internal empirical modes; 3) received further development the method of semantic coding of speech signals based on mel-frequency cepstral coefficients, but using the basic principles of adaptive spectral analysis with the application empirical wavelet transform, which increases the efficiency of this method. Conducted experimental research in the software environment MATLAB R2020b showed, that the developed method of semantic coding of speech signals based on empirical wavelet transform allows you to reduce the encoding speed from 320 to 192 bit/s and the required passband from 40 to 24 Hz with a probability of error-free recognition of about 0.96 (96%) and a signal-to-noise ratio of 48 dB, according to which its efficiency increases 1.6 times in contrast to the existing method. The results obtained in the thesis can be used to build systems for remote interaction of people and robotic equipment using speech technologies, such as speech recognition and synthesis, voice control of technical objects, low-speed encoding of speech information, voice translation from foreign languages, etc.
