Quasi-real time translation of morse-coded signals using digital delay processing.
… thesis investigates the problems in automatic translation of Morse-coded signals. Specific modifications to a commercially available decoder are made and evaluated. The delay algorithm presented is based upon the attributes of a human operator and is implemented using integrated circuit static …

Sensemble : a wireless inertial sensor system for the interactive dance and collective motion analysis
… for interactive performance demands the real-time translation of data into an efficient feature set that a composer, designer, or choreographer can interpret. Now that it is possible to extend expressive motion sensing to multiple points on multiple dancers, an interactive system is capable of …

Generating Canonical Sentences from Question-Answer Pairs of Deposition Transcripts
… and ``Grass Script" to Certified Access Real-time Translation (CART). Since the boom of digitization, there has been a shift to storing these in the PDF/A format. Deposition transcripts are in the form of question-answer (QA) pairs and can be quite lengthy for common people to read. This gives …

Symmetries, unitarity and positivity of cosmological effective field theories
… Theory (QFT) and General Relativity (GR). The time dependence of cosmological spacetimes, upon which quantum fields propagate, spontaneously breaks time translation and Lorentz boost invariance. Thus the usual tools of particle physics, which assume full Lorentz invariance, need to be adapted …

A General Study of the Complex Ginzburg-Landau Equation
… with additive noise. Due to the fact that time translation invariance is broken following a critical quench from a random initial configuration, an independent ``initial-slip'' exponent emerges to describe the crossover temporal window between microscopic time scales and the asymptotic …

Driven Magnetic Flux Lines in Type-II Superconductors: Nonequilibrium Steady States and Relaxation Properties
… slow power-law relaxation, breaking of time-translation invariance, and the presence of the dynamical scaling. We measure the dynamical exponents b and lambda_c/z and compare to other work. We find exponent values increase for increasing pinning strength, smaller interaction range, lower …

Topics in gauge/gravity duality
… on a $(d+1)$-dimensional ``bulk"" spacetime, enabling one to extract interesting information about the field theory spectrum and dynamics by performing relatively simple semi-classical calculations using standard general relativity techniques. Although much of the original progress in …

Relaxation and Spontaneous Ordering in Systems with Competition
… manifests in both the formation of space-time patterns in reaction-diffusion systems and collective rhythmic behaviors in coupled oscillators. In this thesis, we present the results of two studies: 1) The response of a multi-species predator-prey system to perturbation. 2) The features of …

Effect of control interface implementation on operation of a multi degree of freedom telerobotic arm
… scenarios must be able to be directed in real time to react to environmental unknowns. In this work, use of a fully-wearable gesture system was proposed to provide control of the robot to the human in the field. A wearable gesture interface would allow user mobility in the field, would allow …

Decay for quasilinear wave equations on cosmological black hole backgrounds
… on subextremal Schwarzschild de Sitter spacetimes. These are integrated decay statements whose bulk energy density, though degenerate at highest order, is everywhere comparable to the energy density of the boundary fluxes. As a corollary, we prove that solutions of the Klein Gordon equation …

Topological phases, non-equilibrium dynamics and parallels of black hole phenomena in condensed matter
… dynamical evolution of the ground state under time variation of a Hamiltonian parameter is studied. The key result is the failure of the ground state to evolve into opposite parity sectors under the dynamical tuning of the system within the topological phase. This dramatic lack of adiabaticity …

Time-resolved linear and non-linear rheology of thixotropic and aging complex fluids: Application to particulate and biopolymeric physical gels
… or breakdown of microstructure is commonly both time– and shear-rate (or shear-stress)–dependent resulting in a range of complex phenomena collected under the term thixotropy. It is becoming increasingly im- portant to develop time-resolved rheometric techniques to quantify the behavior of …

Novel Rheometric Techniques and Constitutive Models for Linear and Nonlinear Rheology: Applications to Polymeric Solutions and Colloidal Gels
… these complex fluids is important for predicting time-varying material performance under various processing conditions, thus helping prevent failures in large-scale industrial operations. However, modeling the rheological behavior of such complex fluids using canonical constitutive laws that …

Ontogenetic and comparative aspects of cerebellar and motor development
… improve in precision and are at the same time continuously calibrated to the changing body dimensions. The cerebellum is critical for movement coordination and adaptation in adults. Also, interfering with cerebellar development during early life causes behavioural deficits suggesting an …
