The goal of developing high fidelity simulation of muscle force is of considerable interest for the biomedical community. Traditionally Hill models have been incorporated. However, feasible scope of the Hill model is inherently limited, especially in light of the growing relevance of muscle history dependence. History dependence is considered to be significant for motor control and stability. Attempts...
Muscle's contractile properties are complicated by its viscoelastic properties. Failure of early viscoelastic muscle models led to Hill's force-velocity relation embodied as the contractile element. Adopting a particular force-velocity relation to describe muscle is neither easy, nor unique [1]. Time-varying elastance based models of the left ventricle have been popular since the idea was presented...
This paper presents a mass-spring model for real-time simulation of volume preserving deformable solids. A new type of springs that show collective behavior was developed called “support springs”, which model the “matter” inside the object and make it preserve its volume without the need of explicit volume computations during the simulation as it is done in conventional methods. Comparing the volume...
This paper builds a two dimensional oculomotor plant mathematical model (2DOPMM) that is capable of generating eye movement trace on a two dimensional plane. The key difference between the proposed model and the models presented previously is a design that is geared towards linearity and capability of integration into a real-time human computer interaction system while providing force output for each...
This paper introduces volume springs that provide the volume effect to a surface model when it is deformed. The estimation of the properties of the model takes the real material properties into consideration, where each spring stiffness is derived based on the elasticity, rigidity and compressibility modulus. The proposed model can be adopted to simulate soft objects such as a deformable human breast,...
