Biomechanical Modeling of Hip Abduction Exercise Using Optimized Inverse Dynamics

Voice source analysis using biomechanical modeling and glottal inverse filtering

This paper studies the use of glottal inverse filtering together with a biomechanical model of the vocal folds to simulate the glottal flow waveform. The glottal flow waveform is first estimated by inverse filtering the acoustic speech pressure signal of natural speech. The estimated glottal flow is used as a template in an optimization process which searches for a set of parameters for a deter...

Inverse modeling of HEM data using a new inversion algorithm

Helicopter-borne frequency-domain electromagnetic (HEM) surveys are used extensively for mineral and groundwater exploration and a number of environmental investigations. To have a meaningful interpretation of the measured multi- frequency HEM data, in addition to the resistivity maps which are provided in each frequency or for some particular depth levels, it is a necessity ...

Dynamics kin deformation based on biomechanical modeling

Animating the human body with realistic skin deformation is a big challenge. Current approaches rely on approximations by using simple techniques such as skinning. We propose an approach based on the simulation of the deformation of the underlying musculoskeletal model. Our approach is based on subject-specific models that are constructed from medical images, 3D body scanner data and motion cap...

Hip-abduction, knee-extension orthosis.

T he Hip-Abduction, KneeExtension Orthosis (HA, KE) is designed to aid in preventing or correcting deformities in spastic hip abductor and hamstring muscles when stretching and exercise do not suffice. Spasticity in this group of muscles is not uncommon in paraplegia or in other selected diseases of the central nervous system-for example, in multiple sclerosis. The orthosis consists of bila ter...
