Dissipative Contact Force Models
2016In this chapter, some of most relevant dissipative contact force models utilized in multibody dynamics are presented. In particular, attention is given to the constitutive laws proposed by Kelvin and Voigt, Hunt and Crossley, Lankarani and Nikravesh, and Flores et al. Additionally, other nonlinear contact force models are briefly presented. The contact

Proceedings of the 2008 ACM symposium on Virtual reality software and technology, 2008
In this paper we investigate attraction techniques, using the haptic modality, for CAD applications. An important issue in CAD systems is the modification of the Boundary Representation (B-Rep) of 3D objects. However, this fundamental task is possible only if a geometric element (vertex, edge, face) has already been selected.

HIERARCHICAL MODELING OF A FORCED ROBERTS DYNAMO
International Journal of Bifurcation and Chaos, 2007We investigate the dynamo effect in a flow configuration introduced by G. O. Roberts in 1972. Based on a clear energetic hierarchy of Fourier components on the steady-state dynamo branch, an approximate model of interacting modes is constructed covering all essential features of the complete system but allowing simulations with a minimum amount of ...

Modeling of force sensing and validation of disturbance observer for force control
IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat. No.03CH37468), 2004Controlling robots in contact with the environment is an important problem in industry applications. Generally, a force sensor is used for sensing the external force. It is well known that information of a force sensor has much noise. Furthermore, unstable state is also caused by the narrow bandwidth of force information by a force sensor.

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2003
This paper presents a hybrid modelling (HM) approach, which uses a fuzzy logic (FL) wheel-force modelling of the non-trivial case of a non-holonomic 4/spl times/4 wheeled skid steer small-scale electric vehicle. An analytical vehicle-actuator explicit model was firstly derived by explicitly modelling the permanent magnet direct current machines which ...

Forced Model Equation for Turbulence
The Physics of Fluids, 1969An artificial random force is introduced into Burgers' model equation for turbulence. This forced model equation is solved numerically as an initial-value problem. Both the driving force and initial velocity field are assumed Gaussian and are generated by a white noise process. Many statistical properties of this model for turbulence are studied.

A Nonlinear System Model of Isometric Force
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006The analysis of isometric force may provide early detection of certain types of neuropathology such as Parkinson's disease. Our long term goal is to determine if there are detectable differences between model parameters of healthy and unhealthy individuals.

Force Fields for Homology Modeling
2011Accurate all-atom energy functions are crucial for successful high-resolution protein structure prediction. In this chapter, we review both physics-based force fields and knowledge-based potentials used in protein modeling. Because it is important to calculate the energy as accurately as possible given the limitations imposed by sampling convergence ...

The force model: concept, behavior, interpretation
Proceedings of the 2004 Congress on Evolutionary Computation (IEEE Cat. No.04TH8753), 2004Most experiments in research on autonomous agents and mobile robots are performed either in simulation or on robots with static physical properties; evolvable hardware is hardly ever used. One of the very rare exceptions is the eyebot on which Lichtensteiger and Eggenberger (1999) have evolved simplified insect eyes. Even though substantially improved,
