Port-Hamiltonian modeling for soft-finger manipulation [PDF]
2003 IEEE International Conference on Robotics and Automation (Cat. No.03CH37422), 2010 In this paper, we present a port-Hamiltonian model of a multi-fingered robotic hand, with soft-pads, while grasping and manipulating an object. The algebraic constraints of the interconnected systems are represented by a geometric object, called Dirac ...

On chain models for contact electrification [PDF]
Journal of Physics: Condensed Matter, 2022 Abstract An exact analytical model of charge dynamics for a chain of atoms with asymmetric hopping terms is presented. Analytic and numeric results are shown to give rise to similar dynamics in both the absence and presence of electron interactions.

Simplified DEM-Based Modelling and Simulation of the Track Ballast
Buildings, 2023 This study proposes a rational method for modelling ballast in tracks based on the discrete element method (DEM) approach. To simulate a ballast consisting of a group of gravels, it is essential to use the discrete element method.

Modeling the Emergence of Contact Languages [PDF]
PLOS ONE, 2015 Contact languages are born out of the non-trivial interaction of two (or more) parent languages. Nowadays, the enhanced possibility of mobility and communication allows for a strong mixing of languages and cultures, thus raising the issue of whether there are any pure languages or cultures that are unaffected by contact with others. As with bacteria or

Contact Hypersensitivity as a Murine Model of Allergic Contact Dermatitis
Journal of Visualized Experiments, 2022 Contact hypersensitivity (CHS) is an experimental model of allergic contact dermatitis (ACD) that can be studied in mice. This study aims to present an objective laboratory method that may help to study the CHS reaction in mice, which can be measured and quantified by various tests. To induce CHS, on day "0", mice were sensitized on a previously shaved
