This paper presents tip-grasp experiences with a robotic hand with three 1 dof anthropomorphic fingers of human sizes. The last prototype of LARM Hand built at LARM in Cassino is illustrated as a low-cost easy-operation design. Cylindrical-grasp experiences have been previously carried out in order to compare the force measure results with the force results that are measured during the tip-gras...

A prerequisite for rehabilitation is that patients preserve their ability to adapt to novel dynamic environments, an ability that has been associated with the cerebellar system. In this study, we use a robot manipulandum to assess the ability of multiple sclerosis (MS) subjects in the early phase of the disease to adapt to a speed-dependent force field. Their performance is compared with an equ...

A methodology is given to determine the effect of different mass distributions for triatomic reactions using the geometry of shape space. Atomic masses are incorporated into the non-Euclidean shape space metric after the separation of rotations. Using the equations of motion in this non-Euclidean shape space, an averaged field of velocity-dependent fictitious forces is determined. This force fi...

[Abstract] Using the gauge field model with massive gauge bosons, we could construct a new model to describe the strong interaction. In this new quantum chromodynamics(QCD) model, we will introduce two sets of gluon fields, one set is massive and another set is massless. Correspondingly, there may exists three sets of glueballs which have the same spin-parity but have different masses. A possib...

Recent advances in biomolecular modeling have emphasized the importance of inclusion of explicit electronic polarizabilty, and a description of electrostatic interactions that includes atomic multipoles; however, these additional levels of treatment necessarily increase a model’s computational cost. Ultimately, the decision as to whether inclusion of these more rigorous levels are justified res...

An exact solution for the Casimir force between two arbitrary dielectric gratings with the same period d is presented. The Casimir energy for two dielectric gratings or periodic dielectrics is expressed in terms of Rayleigh coefficients. The theory is applied to calculate the Casimir force in several cases of interest.

A model of human behavior is first presented based upon the force field analysis of Lewin. This model includes feedback forces and represents the entire system rather than isolated parts. The model is constructed with weights and input forces; these are combined to produce output forces which are fed back to other components. A questionnaire is used to gather the input for the model, and the re...

We consider liquid drops or crystals lying in equilibrium under the action of a potential energy. For small masses, the proximity of the resulting minimizers from the Wulff shape associated to the surface tension is quantitatively controlled in terms of the smallness of the mass and with respect to the natural notions of distance induced by the regularity of the Wulff shape. Stronger results ar...

With pondered task assignment methods which utilize the dynamic state of the grid resources to solve task-to-processor mappings, an important problem arises from the difficulty of collecting the information from the remote nodes. In this paper we show that with the use of the force field method for task assignment, the information collection is not a problem and the method outperforms random no...
