Abstract (sommario):

A new method for musical steganography for the MIDI format is presented. The MIDI standard is a user-friendly music technology protocol that is frequently deployed by composers of different levels of ambition. There is to the author’s knowledge no fully implemented and rigorously specified, publicly available method for MIDI steganography. The goal of this study, however, is to investigate how a novel MIDI steganography algorithm can be implemented by manipulation of the velocity attribute subject to restrictions of capacity and security. Many of today’s MIDI steganography methods—less rigorously described in the literature—fail to be resilient to steganalysis. Traces (such as artefacts in the MIDI code which would not occur by the mere generation of MIDI music: MIDI file size inflation, radical changes in mean absolute error or peak signal-to-noise ratio of certain kinds of MIDI events or even audible effects in the stego MIDI file) that could catch the eye of a scrutinizing steganalyst are side-effects of many current methods described in the literature. This steganalysis resilience is an imperative property of the steganography method. However, by restricting the carrier MIDI files to classical organ and harpsichord pieces, the problem of velocities following the mood of the music can be avoided. The proposed method, called Velody 2, is found to be on par with or better than the cutting edge alternative methods regarding capacity and inflation while still possessing a better resilience against steganalysis. An audibility test was conducted to check that there are no signs of audible traces in the stego MIDI files.

Abstract (sommario):

This paper describes the development of a low cost, compact and portable automated piano player CantaPlayer. The system accepts digital MIDI (Musical Instrument Digital Interface) files as input and develops pushing actions against piano keys which in turn produces sounds of notes. CantaPlayer uses Pure Data, an audio processing software to parse MIDI files and serve as user interfaces. The parsed information will be sent to Arduino, an open source microcontroller platform, via serial communication. The Arduino I/O pins will be triggered based on the information from Pure Data of which connected transistors will be activated, acting as a switch to draw in larger power supply to power the solenoids. The solenoids will then push the respective piano keys and produce music. The performance of CantaPlayer is evaluated by examining the synchronousness of the note playing sequence for a source MIDI and the corresponding reproduced MIDI. Three types of MIDI playing sequence (scale, polyphonic and rapid note switching) were tested and the results were satisfactory.

Abstract (sommario):

In order to protect the security of information networks, a dedicated MIDI audio steganalysis algorithm is proposed. The least significant bit embedding scheme in MIDI audio is discussed, and the parameter of music velocity is picked up, and the steganalysis in MIDI audio based on entropy estimation is analyzed. Experiments show that when embedded rate is high, FPR and FPR are all slow, and the entropy estimation could be taken as a dedicated MIDI audio steganalysis algorithm.

Abstract (sommario):

This work reports development of a MIDI-to-Singing song synthesis that will produce audio files from MIDI data and arbitrary Romaji lyrics in Japanese. The MIDI-to-Singing system relies on the Flinger (Festival singer) for singing voice synthesis. Originally, this MIDI-to-Singing system was developed by English. Based on some Japanese pronunciation rules, a Japanese MIDI-to-Sing synthesis system was developed and derived. For a language transfer like Festival synthesized singing, two major tasks are the modifications of a phoneset and a lexicon. Originally, MIDI-to-Sing song synthesis can create singing voices in many languages, but there is no existing Japanese festival diphone voice available right now. We therefore used a voice transformation model in festival to develop Japanese MIDI-to-Singing synthesis. An evaluation of a song listening experiment was conducted and the result of this voice conversion showed that the synthesized singing voice successfully migrate from English to Japanese with high voice quality.

Abstract (sommario):

The Yale-Classical Archives Corpus (YCAC) contains harmonic and rhythmic information for a dataset of Western European Classical art music. This corpus is based on data from <a href="http://www.classicalarchives.com/">classicalarchives.com</a>, a repository of thousands of user-generated MIDI representations of pieces from several periods of Western European music history. The YCAC makes available metadata for each MIDI file, as well as a list of pitch simultaneities ("salami slices") in the MIDI file. Metadata include the piece's composer, the composer's country of origin, date of composition, genre (e.g., symphony, piano sonata, nocturne, etc.), instrumentation, meter, and key. The processing step groups the file's pitches into vertical slices each time a pitch is added or subtracted from the texture, recording the slice's offset (measured in the number of quarter notes separating the event from the file's beginning), highest pitch, lowest pitch, prime form, scale-degrees in relation to the global key (as determined by experts), and local key information (as determined by a windowed key-profile analysis). The corpus contains 13,769 MIDI files by 571 composers yielding over 14,051,144 vertical slices. This paper outlines several properties of this corpus, along with a representative study using this dataset.

Abstract (sommario):

Music is a type of time-series data. As the size of the data increases, it is a challenge to build robust music genre classification systems from massive amounts of music data. Robust systems require large amounts of labeled music data, which necessitates time- and labor-intensive data-labeling efforts and expert knowledge. This paper proposes a musical instrument digital interface (MIDI) preprocessing method, Pitch to Vector (Pitch2vec), and a deep bidirectional transformers-based masked predictive encoder (MPE) method for music genre classification. The MIDI files are considered as input. MIDI files are converted to the vector sequence by Pitch2vec before being input into the MPE. By unsupervised learning, the MPE based on deep bidirectional transformers is designed to extract bidirectional representations automatically, which are musicological insight. In contrast to other deep-learning models, such as recurrent neural network (RNN)-based models, the MPE method enables parallelization over time-steps, leading to faster training. To evaluate the performance of the proposed method, experiments were conducted on the Lakh MIDI music dataset. During MPE training, approximately 400,000 MIDI segments were utilized for the MPE, for which the recovery accuracy rate reached 97%. In the music genre classification task, the accuracy rate and other indicators of the proposed method were more than 94%. The experimental results indicate that the proposed method improves classification performance compared with state-of-the-art models.

Abstract (sommario):

Il progetto realizzato consiste in uno strumento software in grado di effettuare una conversione di file, dal formato MIDI al formato MusicXML. Il tool è il proseguimento di un’attività basata sull'analisi di reti complesse e sullo sviluppo di strumenti per la modellazione di spartiti musicali. Melodie, assoli ed in generale tracce musicali sono rappresentabili come reti complesse, in cui i nodi identificano le note del brano e gli archi mostrano le sequenze con cui queste vengono suonate. Utilizzando la teoria delle reti è possibile estrarre alcune metriche principali che caratterizzano il brano in questione. Per la generazione della rete si è fatto uso di spartiti musicali descritti tramite lo standard MusicXML. File in questo formato sono difficilmente reperibili, per cui lo strumento realizzato si propone di effettuare una conversione da formato MIDI a formato MusicXML, con l’obiettivo di ottenere un database più esteso. Attraverso il tool sono stati convertiti brani di diverso genere, le cui reti relative sono state poi analizzate applicandovi le metriche principali ed effettuando le dovute valutazioni.

Abstract (sommario):

En tant que laboratoire national pour la métrologie des rayonnements ionisants, le Laboratoire National Henri Becquerel met au point les méthodes de mesures absolues pour établir les références dosimétriques. Il dispose, entre autres, de références dans des faisceaux de rayons X utilisés en radiothérapie et ayant une taille de champ comprise entre 10 et 2 cm de côté. Afin de s’approcher des plus petits champs utilisés en clinique, la miniaturisation des détecteurs absolus n’étant pas possible, il est proposé dans cette thèse de remplacer la dose absorbée en un point par le produit dose surface (PDS). L’applicabilité du PDS mesuré à l’aide de dosimètres dont la surface sensible est plus grande que celle du champ de rayonnement a été vérifiée. Ainsi, un calorimètre graphite avec une surface sensible de 3 cm de diamètre a été conçu, construit et testé. En vue du transfert des références dosimétriques à l’utilisateur, une chambre d’ionisation de même diamètre a elle aussi été réalisée et testée. Son coefficient d’étalonnage en termes de PDS a été déterminé dans des faisceaux circulaires de 2, 1 et 0.75 cm de diamètre avec une incertitude type inférieure à 0.7 %. La distribution relative de la dose absorbée dans l’eau en deux dimensions a été mesurée au moyen d’un dosimètre diamant, d’une chambre d’ionisation PinPoint et de films gafchromiques, pour lesquels un protocole de lecture spécifique a été mis au point. Les résultats dans le faisceau de 2 cm de diamètre ont montré un bon accord entre les approches en termes de PDS et de dose absorbée dans l’eau en un point, après application des facteurs de correction obtenus au moyen de simulations Monte Carlo et des mesures de distribution de dose. Les coefficients d’étalonnage de la chambre d’ionisation de grandes dimensions établis dans les champs de 1 et 0.75 cm de diamètre sont compatibles aux incertitudes près mais s’écartent de -2.6 % de celui établi dans le champ de 2 cm de diamètre. L’utilisation du PDS nécessite donc une surface de détection notablement plus grande que la section du mini-Faisceau
The French primary standard dosimetry laboratory “Laboratoire National Henri Becquerel” is in charge of the establishment of dosimetric standards for ionizing radiation beams. Absolute dose measurements are thus available for X-Ray beams used in radiotherapy for field sizes between 10 and 2 cm. Since the miniaturization of absolute dosimeters is not possible for smaller field sizes, a dose area product (DAP) has been suggested as a substitute to the absorbed dose at a point.In order to measure a DAP with dosimeters which sensitive surface is larger than the beam, a graphite calorimeter with a sensitive surface of 3 cm diameter was designed, built and tested. An ionization chamber with the same diameter was realized and tested to transfer the dosimetric references to the end users. Its calibration factor in terms of DAP was determined in circular beams of 2, 1 and 0.75 cm diameter with an uncertainty smaller than 0.7 %. The two-Dimension relative dose distribution was measured thanks to a diamond dosimeter, a PinPoint ionization chamber and gafchromic films, using a specific protocol.Both approaches, respectively based on a PDS and an absorbed dose to water at a point, were in good agreement in the 2 cm beam. Correction factors determined from Monte Carlo simulations and measured dose distributions were needed for this comparison. The calibration factor of the large ionization chamber in the 1 and 0.75 cm diameter beams were in good agreement within the uncertainties but a gap of -2.6 % was found with the one established in the 2 cm diameter beam. As a result, the DAP can be used if the sensitive surface is much larger than the beam section

Abstract (sommario):

Quan una aeronau travessa núvols situats a mitja altitud que estan principalment compostos d'incomptables gotes d'aigua en subfusió, corre el risc d’engelament en les seves parts més exposades. Fins i tot una capa submilimètrica de gel formada sobre elements com ales, motors o tubs de pitot pot reduir dràsticament la seva sustentació i rendiment i, per tant, afectar a la seva eficiència i maniobrabilitat fins al punt de causar una pèrdua de control i posterior accident. Les tecnologies anti-gel instal·lades en aeronaus modernes busquen reduir aquest problema mitjançant sistemes que no solament fonguin el gel acumulat si no que ho detectin abans que resulti perillós. En aquesta Tesi es presenta un nou i ultrasensible, però a la vegada robust, sensor de gel basat en fotònica integrada d’IR-mitjà que pot ser muntat en qualsevol superfície sense pèrdua aerodinàmica. A partir de la detecció de canvis en les característiques de l'aigua a l’IR-mitjà que estan associats intrínsecament a variacions en la seva estructura molecular per a les seves diferents fases, es demostra la detecció de gel amb alta sensibilitat i rapidesa per aconseguir una alerta prematura d’engelament en vol. Al llarg d'aquesta Tesi, es tracta, des de les perspectives fonamental i aplicada, el desenvolupament complet del sensor abastant des de la concepció teòrica fins a la demonstració experimental del seu rendiment i fiabilitat en un túnel de vent. Finalment, es presenta un segon sensor amb millor sensibilitat a costa d'una menor robustesa per a la detecció de petits volums de contaminants químics en aigua. El sensor aprofita l'excitació d'un plasmó superficial a l’IR-mitjà que intensifica la interacció entre llum i anàlit al voltant de ressonàncies moleculars. Això emfatitza encara més els enormes beneficis que operar a l’IR-mitjà pot aportar a futurs sensors fotònics integrats.

Abstract (sommario):

Two thin film materials - intermetallic and porous silicon thin films, have been studied in this thesis. The first part focuses on the hydrogen storage and electrochemical properties of single layer LaNi5-based thin films fabricated by magnetron sputtering. The aim is to enhance their performance in mini hydrogen storage systems, and their application as electrodes in thin film Ni-MH micro-batteries. Such LaNi5-based thin films were fabricated by magnetron puttering. Using X-ray diffraction (XRD), these thin films revealed a crystalline structure with uniform chemical composition. Using AFM, SEM and TEM, they were found to have a unique microstructure: (1) Nanopores of approximately 15-40 nm which could possibly act as hydrogen reservoir (2) A dense, defect free cross sectional region which would ultimately improve the efficiency and lifetime of the thin film electrodes used in thin film battery. The hydrogen absorption/desorption behaviour of these thin films were determined by volumetric method. The maximum hydrogen content of the La-Ni-A1 film was found to be 1.45 wt% at 333 K which was very close to the theoretical capacity of 1.47 wt%; and higher than that of the La-Ni-AI powder materials (1.2 wt%). Electrochemical properties of the films were measured by simulated battery tests. When discharged at low current, the discharge capacity of the film was similar to that of powder materials - about 220 mAh/g for the first 30 cycles. When the thin film electrode was discharged at a high rate, 4C (current density of 100 mA/g), it could reach the maximum specific capacity of 200 mAh/g and maintained this capacity for 200 cycles; the value was not attainable for La-Ni-AI powder electrode. The presence of crack propagation in film during charge/discharge cycles would improve the electrochemical performance which was different to that of powder materials. Cyclic voltammetry reported that the efficiency of the film could maintain at 80% for the first 200 cycles and gradually decreased due to the formation of corrosion products on surface, which is consistent with the galvanostatic results. XPS (X-ray Photoelectron Spectroscopy) revealed that the corrosion products ??? A1203, La203 and La(OH)3 formed on the film surface after cyclic voltammetry. The second part reported the hydrogen absorption/desorption behaviour of porous silicon thin films. The hydrogen content was determined quantitatively by both volumetric method and thermogravimetric analysis (TGA) and found to be 15 wt% at 423 K under 15 atm of hydrogen pressure. This is an extraordinary amount of hydrogen absorption which supersedes the US Department of Energy's 2007 target of 6.5 wt%. Hydrogen depth profiles of the film after hydrogenation performed by Secondary Ion Mass Spectroscopy confirmed there was hydrogen within the film structure, this was an indication that hydrogen was not just physisorbed on the film surface, but chemisorbed into the porous Si lattice. X-ray diffraction found that there was a lattice contraction upon hydrogen insertion, again suggesting the hydrogen entered into the film structure by chemisorption.

Abstract (sommario):

AbstractThis chapter examines the role of film and television in embedding sociotechnical imaginaries of civil defence during the early nuclear age (c. 1949–1965) by zooming in on Sweden and Denmark, two neighbouring countries that differed both in terms of their political position in the Cold War and in the scale of their civil defence efforts. Following a theoretical discussion of the psychosocial effects of films and their manner of circulation, we analyse Swedish and Danish films in two periods demarcated by the thermonuclear disruption of civil defence during the mid-1950s. The analysis highlights how films were used to frame technologies and script and perform social norms. We argue that films constitute an important source for understanding the difficulties of embedding sociotechnical imaginaries of civil defence.

Abstract (sommario):

Faced with the representational challenge of visually communicating musical information, we developed Mandrit: a system for automatic generation of musical visualizations for rhythm analysis. It uses data extracted from MIDI files to plot graphs for different songs, representing their rhythmic signatures. The system is customizable and presents new ways to visualize pace through different metrics. We aim to encourage the discussion in this field and the development of tools to generate musical visualizations, as a means to help musicians and scholars in musical analysis, teaching, composing and complementing musical performances.

Abstract (sommario):

Between January 2015 and mid-2020, about 69 of the approximately 2,160 small-to-medium independent oil companies operating in the tight oil sector filed for Chapter 11 protection. These filings mostly occurred in 2016 and 2019. A lack of financial discipline and poor financial risk assessment meant that these companies were negatively impacted by the low oil prices in these years. Hence, they declared bankruptcy.

Abstract (sommario):

Poly-,Per-fluorinated alkyl substances (PFAS) are versatile chemicals that were incorporated in a wide range of products. One of their most important use was in aqueous film-forming foams for fighting liquid fuel fires. PFAS compounds have recently been identified as potential environmental contaminants. In the United States there are hundreds of potential military sites with PFAS contamination. The ERDC designed and constructed a mobile treatment system to address small sites (250,000 gallons or less) and as a platform to field test new adsorptive media. The PFAS Effluent Treatment System (PETS) has cartridge filters to remove sediments and a granular activated carbon (GAC) media filter to remove organic compounds that might compete with PFAS in the ion exchange process, although it may also remove PFAS too. The last process is an ion exchange resin specifically designed to remove PFAS to a target level of 70 ng/L or less (equivalent to the US Environmental Protection Agency (EPA) Drinking Water Health Advisory). The system was tested at Hurlburt Field, a US Air Force facility in Florida and at Naval Support Activity (NSA) Mid-South in Millington, TN.
