This diploma thesis on the topic Home Pet contains art approaches that lead students to a sensitive and conscious behaviour towards animals. The theoretical part presents imaging of an animal in the history of art and possibilities of involvement of the animal themes to Framework Education Programme and School Education Programme for Elementary Art Schools. The thesis also focuses on the relationship between children and animals and the healing power of animals. Further, the thesis discusses the project method of teaching, which was chosen for the given topic at Elementary Art School. The practical part of the thesis was realized in the preparatory year and the first year of Elementary Art Schools in Dačice and Jemnice and reflects the course of my own lesson on the topic Home Pet.

We are developing a tabletop extreme-ultraviolet source using high harmonic generation at Brigham Young University. The thesis goes over the theory of high harmonic generation using the three-step model. This tabletop source was designed for probing magnetic domains of iron nanoparticles. We present optimization of the 42 eV and 52 eV harmonics through phase matching. Phase matching consists of tuning the intensity of the IR beam and pressure of the gas medium. The target gas medium used for this thesis is argon. The 42 eV harmonic was optimized to 8.2 billion photons per second. This was used with a 1500 mm focal-length lens, 15 mm medium length, laser power of 1.53 Watts, and a pressure of 12 Torr of argon gas. The 52 eV harmonic was optimized to 1.5 billion photons per second with a 1500 mm focal-length lens, 20 mm medium length, laser power of 3.29 W, and 14.9 Torr of argon gas. There are two designs for selection of harmonics: 1) a tunable design consisting of a toroidal mirror and flat diffraction grating and 2) a set of normal-incidence extreme-ultraviolet mirrors designed for 42 or 52 eV photons. Magnetic imaging uses x-ray magnetic circular dichroism to obtain magnetic contrast and use it to visualize magnetic nanosystems. Therefore, the high harmonic source also needs to generate circularly polarized light. Generating circularly polarized high harmonics is possible with a bichromatic beam. This is achieved using an apparatus called the MAZEL-TOV designed by Oren Cohen’s group at Technion University in Israel. The MAZEL-TOV consists of a BBO crystal for second harmonic generation, a pair of pulse delay compensation plates, and a quarter-wave plate. These optics are placed inline with the laser beam. We have successfully optimized the circularly polarized extreme-ultraviolet harmonics with the MAZEL-TOV. A spectrometer was made to calibrate the harmonics in the MAZEL-TOV spectrum. The tabletop source was then used to demonstrated coherent diffraction imaging of two pinholes.

In this dissertation, I develop and apply an original voice-leading method to the music of Shostakovich. Between the years of 1926 and 1948, his music involved extreme chromaticism that required analytical views from both Russia and the West. In the mid-twentieth century, Russian theorists such as Lev Mazel' and Alexandr Dolzhansky wrote about the modal language of Shostakovich's works, but their writings lacked how to identify them within extremely chromatic passages. In the West, scholars describe his music as both tonal and atonal, sometimes combined within one work. I unify these two views with my voice-leading system consisting of an intervallic resolution of the doubly augmented prime (DAP), which appears seemingly random on the musical surface, but occurs for specific compositional reasons. First mentioned by name in Aleksei Ogolevets' 1946 "An Introduction into Contemporary Musical Thought," the DAP served no harmonic or modal purpose. While Ogolevets mentions and includes examples that show this interval, he does not discuss its resolutions nor how it functions in musical contexts. This structure, however, has broader conceptual and analytical implications. Therefore, I develop a method based on the voice leading and semitonal resolutions of the DAP, which I apply to the music of Shostakovich. The DAP contributes to his compositional style by functioning in three ways: 1) identifying one mode or two simultaneous modes, 2) completing traditional triadic harmonies, and 3) facilitating both tonal and modal modulations.
