American composer David Kechley was profoundly impacted by a 1990 trip to the Ryoan-ji Temple in Kyoto, Japan. The composer describes the finely raked, small white stones in the midst of fifteen large rocks in the Japanese Zen garden as "planned randomness." Kechley's inaugural composition for saxophone-guitar duo, In the Dragon's Garden, reflects his experience at the Ryoan-ji Temple. The use of minimalistic compositional techniques without literal repetition in the work represents a departure from the first generation of Minimalist composers, such as LaMonte Young, Steve Reich, Phillip Glass, and John Adams. An analysis of minimalistic compositional elements, combined with an interview with the commissioning ensemble, the Ryoanji Duo, provides insights into the interpretation and preparation of this complex work. Furthermore, this document contains helpful information pertinent to the saxophone-guitar duo. Details on balance and amplification, orchestration, and collaboration with the composer will supply performers and composers with essential knowledge needed to participate in this growing musical medium.

Pianists often have trouble in determining where a phrase ends, or in other words, cadence identification. This is especially true of certain cadences that can be considered either as half cadences or authentic cadences. This analytically ambiguous cadential point can result in different performance decisions, so pianists should make informed decisions about what kind of cadence it is. This study aims to investigate such cadential ambiguity shown at points of phrase boundaries by focusing on Chopin's Piano Sonata No. 2 in B-flat minor, Op. 35, first movement. I offer both possibilities (a half cadence or an authentic cadence) at the phrase ending, suggesting a performance-related strategy based on each possibility. My objective is not to support only one cadential status, but to bring up the cadential problem from the analytical perspective and to demonstrate how cadence identification affects performance results. The dissertation is divided into two parts: analysis and performance, so it relies on a combined method of analytical terminologies and performance-related musical elements. In the analysis, the terminology of William Caplin is employed. The performance part refers to several method books written by prestigious piano pedagogues. After an introduction in Chapter 1, Chapter 2 reviews some literature on cadences. Chapter 3 specifically analyzes the first movement of Chopin's second sonata by means of Caplin's terminologies. Chapter 4 provides a performance-related method and Chapter 5 deals with a practical performance strategy.

The Peabody Conservatory commissioned Estudios De Frontera by Alejandro Viñao in 2004. Percussionist Robert Van Sice initiated the commissioning process. Estudios De Frontera is the first composition for percussion ensemble by Viñao. Viñao's Estudios is written in two movements. The first is titled Homage to Nancarrow. As the title implies the compositional processes are directly influenced by Conlon Nancarrow. The composer states: "Homage to Nancarrow is concerned with the perceptual illusion of multiple simultaneous speeds or tempi....This movement explores the type of rhythms that create the illusion that multiple independent tempi are being heard while remaining playable by musicians." The purpose of this document is to provide a rhythmic analysis describing the techniques used by Chopin, Ligeti, and Nancarrow, and demonstrating their manifestation in the first movement of Alejandro Viñao's Estudios de Frontera. The analysis provides detailed information in regards to Nancarrow's rhythmic structures including: ostinato, hemiola, isorhythm, accelerations, and implied poly-tempo. Additionally, by seeking advice from notable performers and ensembles, the areas of greatest concern are identified, and strategies towards rehearsal and performance are recommended. The performance guide is included as an appendix to the analytic body of the paper.

The topic of my thesis is "Information security management in healthcare organization." Medical facilities are generally the ones who should put emphasis on information security. For my thesis I chose aesthetic private clinic called Visage, I underwent safety analysis. The analysis showed that only a small part of the security process is documented in the clinic. This is particularly deficient in terms of business. There may be a leak of sensitive information on the health status of individual patients. It is necessary to better treat the handling of these data. The aim of this thesis is a security manual that will describe the personal, physical and IT security.

Cette thèse est une contribution à la modélisation et à l'étude expérimentale de cavités à cristaux photoniques à fente développées en vue d’un intégration hybride de matériaux actifs sur silicium. Parmi les travaux de conception, nous avons d'abord utilisé la méthodes des ondes planes et la méthode des différences finies (FDTD) pour concevoir une série de cavités SOI à hétérostructures, mécaniquement robustes, infiltrées par des liquides d’indices (n environ 1,5), présentant des longueurs d'onde de résonance dans la gamme des télécommunications (1,3 μm - 1,6 μm), des facteurs de qualité de plusieurs dizaines de milliers, et des volumes modaux proches de 0,03 (lambda/n)3. Nous avons ensuite étudié analytiquement et numériquement le couplage entre une cavité à cristaux photoniques à fente et un guide d'onde à fente par la théorie des modes couplés, complétée par des simulations FDTD, qui ont permis de confirmer la possibilité d'exciter efficacement les modes de fente des cavités à partir d'un guide externe. Enfin, nous avons étudié numériquement et semi-analytiquement des géométries de molécules photoniques constituées de deux cavités à cristaux photoniques à fentes couplées, dont l’écart fréquentiel entre les supermodes a pu être ajusté en amplitude et en signe. Nous avons utilisé une méthode perturbative (« Tight binding ») pour estimer les distributions spatiales des modes des molécules photoniques et prédire leurs fréquences dans plusieurs configurations de cavités à cristaux photoniques à fentes couplées.Ce travail exploratoire a été complété par une partie expérimentale qui a porté sur l'étude d'une famille de cavités de hétérostructure à cristaux photoniques à fente. Les cavités à cœur creux fabriquées ont montré des facteurs de qualité (Q) de plusieurs dizaines de milliers, associés à des volumes modaux de l’ordre de V=0,03 (λ/n)^3 après infiltration de la fente et des trous des structures par des liquides d'indice de réfraction proches de 1,46. Des facteurs Q/V supérieurs à 600 000 et atteignant 1 000 000 dans le meilleur des cas (vers lambda=1,3µm) ont ainsi été observés. Cette phase expérimentale préliminaire a donné ensuite lieu à deux types de développements.Tout d'abord, les propriétés des cavités à cristaux photoniques à fentes ont été étudiées pour des applications en détection d'indice en volume, et testées en utilisant différents liquides d'indice de réfraction compris entre 1,345 à 1,545. Les résonateurs étudiés ont présenté des sensibilités de ~ 235 nm / RIU et des facteur de mérite de détection d'indice de l’ordre de 3700, à l’état de l’art pour des résonateurs silicium intégrés à cœur creux.Dans une autre direction, le potentiel des résonateurs diélectriques à fente a été exploré en vue d’une intégration des matériaux actifs sur silicium. Un polymère dopé aux nanotubes de carbone semiconducteurs a été déposé comme matériau de couverture en vue d’étudier le renforcement de la photoluminescence (PL) des nano-émetteurs sous pompage optique vertical à lambda=740nm. Les expériences conduites ont permis de corréler le renforcement de la PL des nanotubes avec les modes de résonance des cavités et de démontrer le couplage partiel de cette PL vers des guides SOI longs de plusieurs millimètres (collection par la tranche vers lambda=1.3µm), apportant une preuve de principe d’une possible intégration des nanotubes émetteurs en photonique sur silicium. / This Ph.D. work is a contribution to the modeling and the experimental study of slot photonic crystal cavities for hybrid on-silicon integration. Among the design works, we first have used plane the wave expansion and finite-difference time-domain methods to design a series of mechanically robust (non-free membrane) SOI slot photonic crystal heterostructure cavities with resonance wavelengths in the telecommunication range, i.e. from 1.3 µm – 1.6 µm, with Q-factors of around several tens of thousands and mode volumes around 0.03(lambda/n)^3 after being infiltrated by cladding materials with typical index values around 1.5. We have then analytically and numerically studied the coupling between a slot photonic crystal cavity and a slot photonic crystal waveguide by using the coupled mode theory and FDTD simulation. Then we confirmed the ability to excite the cavity slot modes from a waveguide by using FDTD simulation. Finally, as a preliminary step towards the use of several coupled slotted cavities for future hybrid integration schemes, we have numerically and semi-analytically investigated photonic molecules made of two coupled slot photonic crystal cavities providing two different supermodes (bonding and antibonding ones) with controllable wavelength splitting. We successfully employed the tight-binding (TB) approach, which relies on the overlap of the two tightly confined cavity electric fields, to predict the supermodes frequencies and spatial distributions in several coupled slot photonic crystal cavity configurations.This exploratory work was supplemented by an experimental part, which focused on the investigation of a family of slot photonic crystal heterostructure cavities. The fabricated silicon on insulator hollow core cavities showed quality factors of several tens of thousands, i.e. from 18,000 to 31,000 and mode volume V of ~0.03(λ/n)3 after being infiltrated with liquids of ~1.46 refractive index, yielding Q/V ratio larger than 600,000, and reaching 1,000,000 in the best case (at λ ≈ 1.3 μm).This preliminary experimental stage gave rise to two types of additional developments.Firstly, the properties of the studied slot photonic crystal cavities have been investigated for index sensing applications by using different liquids with refractive index values ranging from 1.345 to 1.545. The considered photonic crystal resonators have demonstrated quality factors of several tens of thousands with sensitivities of ~235 nm/RIU and index sensing FOMs around 3,700, i.e. at the state of the art considering hollow core silicon integrated resonators.Secondly, in the view of the integration of active materials on silicon, the potential of these hollow core nanoresonators has been considered to enhance the photo-luminescence (PL) of semiconductor single-walled carbon nanotubes (SWNTs) integrated in thin films deposited on top of silicon. We have brought the first experimental demonstration of SWNTs PL collection (around lambda=1.28 µm) under vertical pumping at short wavelength (lambda=740 nm) from a slotted resonator into millimeter long integrated silicon waveguides, providing a first proof-of-concept step towards nanotube/Si-PhC integration as an active photonic platform. The reported works demonstrate the feasibility of integrating telecommunication wavelength nanotube emitters in silicon photonics as well as emphasize the role of slot photonic crystal cavities for on-chip hybrid integration.
