As the application of interactive media systems expands to address broader problems in health, education and creative practice, they fall within a higher dimensional space for which it is inherently more complex to design. In response to this need an emerging area of interactive system design, referred to as experiential media systems, applies hybrid knowledge synthesized across multiple disciplines to address challenges relevant to daily experience. Interactive neurorehabilitation (INR) aims to enhance functional movement therapy by integrating detailed motion capture with interactive feedback in a manner that facilitates engagement and sensorimotor learning for those who have suffered neurologic injury. While ...

Nanocrystalline (nc) thin films exhibit a wide range of enhanced mechanical properties compared to their coarse-grained counterparts. Furthermore, the mechanical behavior and microstructure of nc films is intimately related. Thus, precise control of the size, aspect ratio and spatial distribution of grains can enable the synthesis of thin films with exceptional mechanical properties. However, conventional bottom-up techniques for synthesizing thin films are incapable of achieving the microstructural control required to explicitly tune their properties. This dissertation focuses on developing a novel technique to synthesize metallic alloy thin films with precisely controlled microstructures and subsequently characterizing their mechanical properties using in ...

In this work, the hydrodynamics of Suction Stabilization is studied. Suction stabilization was found to stabilize floating platforms/floats in a much better way as compared to the conventional methods. This was achieved by an effective increment in the metacentric height due to the Inverse Slack Tank (IST) effect. The study involves the analysis of the existing designs and optimizing its performance. This research investigates the stability of such floats and the hydrodynamic forces acting on the same for offshore applications, such as wind turbines. A simple mathematical model for the condition of parametric resonance is developed and the results are ...

The symphonies of Gustav Mahler (1860 - 1911) constitute an essential element of the orchestral repertory; they are therefore essential for young conductors to understand and for instrumentalists to play. Yet they are impractical in many school situations because they call for large orchestras. One solution to this problem is for the conductor to study the original, full version of the works as Mahler composed them, but to consider performing one of the reduced instrumentations now available. A smaller-scale version provides an opportunity for both the conductor and the instrumentalists to confront the challenges of performing Mahler's music and to ...

Optical Fibers coupled to laser light sources, and Light Emitting Diodes are the two classes of technologies used for optogenetic experiments. Arizona State University's Flexible Display Center fabricates novel flexible Organic Light Emitting Diodes(OLEDs). These OLEDs have the capability of being monolithically fabricated over flexible, transparent plastic substrates and having power efficient ways of addressing high density arrays of LEDs. This thesis critically evaluates the technology by identifying the key advantages, current limitations and experimentally assessing the technology in in-vivo and in-vitro animal models. For in-vivo testing, the emitted light from a flat OLED panel was directly used to stimulate ...

The purpose of this study is to examine and explore Hatha Yoga and how it relates to a practice consisting of singer-friendly yoga postures, how these postures may benefit the singer's mental and physical health, and how these techniques relate to designated research. The study also investigates yogic breathing techniques and how these exercises relate to selected research. Lastly, the paper examines how the voice student and professional singer may alleviate anxiety by introducing a practice of daily yogic mediation of mudra and mantra techniques, and how voice teachers may better understand and assist their students with stage performance anxiety. ...

Breast cancer cell invasion is a highly orchestrated process driven by a myriad of complex microenvironmental stimuli. These complexities make it difficult to isolate and assess the effects of specific parameters including matrix stiffness and tumor architecture on disease progression. In this regard, morphologically accurate tumor models are becoming instrumental to perform fundamental studies on cancer cell invasion within well-controlled conditions. In this study, the use of photocrosslinkable hydrogels and a novel, two-step photolithography technique was explored to microengineer a 3D breast tumor model. The microfabrication process presented herein enabled precise localization of the cells and creation of high stiffness ...

This research paper recounts the work done in founding an opera company and putting on its inaugural show. It also provides some of the insights acquired during the process, which may be helpful for other future opera producers in creating a framework and guideposts for starting their own companies. The paper consists of two main sections followed by several short appendices. The first section methodically reconstructs the process by which Windy City Opera's La Bohème was brought to the stage. It covers the background experiences that prompted the author to found her own company, the research and decisions involved, and ...

Some cyanobacteria, referred to as boring or euendolithic, are capable of excavating tunnels into calcareous substrates, both mineral and biogenic. The erosive activity of these cyanobacteria results in the destruction of coastal limestones and dead corals, the reworking of carbonate sands, and the cementation of microbialites. They thus link the biological and mineral parts of the global carbon cycle directly. They are also relevant for marine aquaculture as pests of mollusk populations. In spite of their importance, the mechanism by which these cyanobacteria bore remains unknown. In fact, boring by phototrophs is geochemically paradoxical, in that they should promote precipitation ...
