The even-odd staggering observed in the experimental fission-fragment nuclear-charge yields is investigated over a wide systematics of fission fragments measured at Lohengrin in direct kinematics and at GSI in inverse kinematics. The general increase of the even-odd staggering in the fission-fragment charge yields towards asymmetric charge splits is explained by the absorption of the unpaired n...

Dedicated ionization chamber was built and installed to measure the energy loss of very heavy nuclei at 2.7 MeV/u produced in fusion reactions in inverse kinematics (beam of Pb). After going through the ionization chamber, products of reactions on C, O targets are implanted in a Si detector. Their identification through their alpha decay chain is ambiguous when their half-life is short. After c...

Aquatic animals swimming in isolation and in groups are known to extract energy from the vortices in environmental flows, significantly reducing muscle activity required for locomotion. A model for the vortex dynamics associated with this phenomenon is developed, showing that the energy extraction mechanism can be described by simple criteria governing the kinematics of the vortices relative to...

This work is devoted to the development of mechatronic hand that can be used as prosthetic hand and as grasper for humanoid robot. The structure and kinematics of the construction, physical appearance, the principle of fingers flexion were inspired byhumanhand.In order to analyze flexing principle, direct kinematics task and force analysis had defined. This study has allowed define more precise...

Motion planning and redundancy resolution of a multi-segment continuum robot is studied. The direct and inverse kinematics model of the robot is derived assuming a constant radius of curvature in each flexible segment of the robot. Due to the primary and secondary backbone structure of the segment, each segment is modelled by two configuration variables and three joint space variables. This int...

Most successful state-of-the-art robo-tic manipulators have the characteristic of producing precise, fast, smooth and reproducible movements. Their drawback is that they tend to have a limited repertoire which can only be extended by costly inverse kinematics calculations or direct teach-in sessions. The goal of our project is to develop a exible open world robot , which adapts to its task and ...

In this paper a method for solving the inverse kinematics of an humanoid robot based on artificial neural networks is presented. The input of the network is the desired positions and orientations of one foot with respect to the other foot. The output is the joint coordinates that make it possible to reach the goal configuration of the robot leg. To get a good set of sample data to train the neu...

The introduction of multiparameter high energy electron momentum spectroscopy (EMS) spectrometers, with high energy and momentum resolution and coincidence count rates, has made it possible to obtain detailed information on the electronic structure of condensed matter and surfaces. In particular it gives direct information on the spectral-momentum density of the material under study, which may ...

this article addresses an efficient and novel method for singularity-free path planning and obstacle avoidance of parallel manipulator based on neural networks. a modified 4-5-6-7 interpolating polynomial is used to plan a trajectory for a spherical parallel manipulator. the polynomial function which is smooth and continuous in displacement, velocity, acceleration and jerk is used to find a pat...
