Children television productions have been using puppets for a long time. Since the early days of computer animation, computer puppet simulation has been researched intensively. Complex motion capture equipment allows nowadays the real time mapping of movement for virtual puppets (performance animation). However, the costs of capturing equipment are too high and the difference in the workflow ma...

[1] Numerous hot springs flow within the steeply incised gorges of the central Nepal Himalayan front. The spring fluids have total dissolved solids (TDS) up to 7000 mg/L and Na, and K typically comprise >50% of the cationic charge, indicating that high-temperature silicate alteration is the dominant source of hot spring alkalinity. HCO3 is normally the dominant anion. Sr isotope ratios from the...

objectives: attached gingival width (agw) is an important marker for diagnosis of periodontal disease and normal gingival sulcus depth (gsd) is a sign of healthy periodontium. the aim of this study was to determine the agw and gsd in3-15 year-olds with three dentition systems in isfahan in 2001.   methods: a total of 360 students (120 students in each system) eligible for this cross sectional s...

This study explores the hypothesis that the sharper, high frequency Korotkoff sounds come from resonant motion of the arterial wall, which begins after the artery transitions from a buckled state to an expanding state. The motions of one mass, two nonlinear springs, and one damper, driven by transmural pressure under the cuff, are used to model and compute the Korotkoff sounds according to prin...

This paper presents an open-loop control method for suppressing payload oscillation or swing caused by operator commanded maneuvers in rotary boom cranes and the method is experimentally verified on a one-sixteenth scale model of a Haggluncls shipboard crane. The crane configuration consists of a payload mass that swings like a spherical pendulum on the end of a lift-line which is attached to a...

An improved mass-spring model for a dripping faucet is presented. The model is constructed based on the numerical results which we recently obtained from fluid dynamical calculations. Both the fluid dynamical calculations and the present mass-spring model exhibit a variety of complex behavior including transition to chaos in good agreement with experiments. Further, the mass-spring model reveal...

We analysed the execution of multijoint pointing movements in humans while weight or spring loads were applied to the pointing hand. Visual feedback on arm and hand position was excluded. Movement paths, final positions, and normalized velocity profiles were found to be load-independent, except for the very first movement after a load change. With increasing size of a weight load movement veloc...

Integrative approaches to studying the coupled dynamics of skeletal muscles with their loads while under neural control have focused largely on questions pertaining to the postural and dynamical stability of animals and humans. Prior studies have focused on how the central nervous system actively modulates muscle mechanical impedance to generate and stabilize motion and posture. However, the qu...

The coupled motion between shallow water sloshing in a moving vessel with baffles and the vessel dynamics is considered. Here the vessel dynamics is restricted to horizontal motion such as in Tuned Liquid Dampers. It was shown by Turner et al. [20] (Phys. Fluids (2013) 25(10) 112102) that partitioning a moving vessel into n separate compartments leads to an interesting dynamical behaviour of th...
