There has been a recent paradigm shift in the computer animation industry with an increasing use of pre-recorded motion for animating virtual characters. A fundamental requirement to using motion capture data is an efficient method for indexing and retrieving motions. In this paper, we propose a flexible, efficient method for searching arbitrarily complex(More)

Novel extended tetrahedral forms of CO2 have been synthesized recently under high-pressure conditions. We perform ab initio density functional theory calculations to investigate whether doping with Si can extend the stability range of such tetrahedral forms of CO2 to ambient pressure. Calculations are performed with a simple cubic cell containing eight(More)
Two different soft-chemical, self-assembly-based solution approaches are employed to grow zinc oxide (ZnO) nanorods with controlled texture. The methods used involve seeding and growth on a substrate. Nanorods with various aspect ratios (1-5) and diameters (15-65 nm) are grown. Obtaining highly oriented rods is determined by the way the substrate is mounted(More)
New multicomponent equiatomic rare earth oxides (ME-REOs) containing 3-7 rare earth elements (Ce, Gd, La, Nd, Pr, Sm and Y) in equiatomic proportions are synthesized using nebulized spray pyrolysis. All the systems crystallized as a phase pure fluorite type (Fm3[combining macron]m) structure in spite of the high chemical complexity. A nominal increase in(More)
A high speed moirC photography system has been developed for measuring dynamic 2-D strain fields. The method is illustrated by an impact onto tiles of Silicon Carbide to display the history of the strain field. The steel blunt cylinder projectile is fired by a gas gun at a speed of 330 m/s. A checked grating with 28 lineslmm was reproduced on the target(More)
Red light emitting cubic Zr0.99Eu0.01O2:Li(+) (0-9 mol%) nanoparticles are synthesized by a low temperature, self-propagating solution combustion method using oxalyl di-hydrazide (ODH) as fuel. In this study, we report systematic investigation of the effect of lithium ion (Li(+)) concentration on the structural properties and the photoluminescence of(More)
LaTiO2 N photocatalysts were prepared by thermal ammonolysis of flux-synthesized La2 Ti2 O7 and La2 TiO5 , and were investigated for water oxidation. Though LaTiO2 N derived from La2 TiO5 appears defect-free by UV/Vis/near-IR and electron paramagnetic resonance (EPR) spectroscopy, its performance is much lower than that of conventional La2 Ti2 O7 -derived(More)
