In this paper we extend previous work [Aubel00] and propose a muscle model suitable for computer graphics based on physiological and anatomical considerations. Muscle motion and deformation is automatically derived from an action line that is deformed using a 1D mass-spring system. The resulting model is fast and can accommodate most superficial human muscles.

We present a straightforward method for estimating the parameters of a physical mass-spring model of the vocal folds using a glottal flow signal. Initial experiments show that the method can successfully be used to model the glottal flow waveform. Parameters obtained can be used to characterise the underlying physical system in, for example, when used as features for speech recognition applicat...

A multi-objective evolutionary algorithm is applied to optimize the design of a helical spring made out of a composite material. The criteria considered are the minimization of the mass along with the maximization of the stiffness of the spring. Considering the computation time required for finite element analyses, the optimization is performed using approximate relations between design paramet...

The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...

In the literature, it has been hotly debated whether the brain uses internal models or equilibrium point (EP) control to generate arm movements. EP control involves specification of EP trajectories, time series of arm configurations in which internal forces and external forces are in equilibrium; if the arm is not in a specified EP, it is driven toward this EP by muscle forces arising due to ce...

Modeling a system means developing mathematical representation to simulate certain properties observed in real systems. These systems can range from car suspension the most complex robotics. In modern mechanical engineering, it is routine model physical dynamic as set of differential equations that will later be simulated using computer. This Use software for numerical analysis and qualitative ...

In this study, we investigated dispersion curves and the band gap structure of a multiresonator mass-in-mass lattice system. The unit cell of the lattice system consists of three separate masses connected by linear springs. It was demonstrated that the band gaps can be shifted by varying the spring constant and the magnitude of the internal masses. By using the conventional monatomic (single ma...
