When creating datasets for modelling of human grasping and manipulation skills based on training examples from human motion one can encounter the problem that the kinematics of the robot does not match the human kinematics. We present a simple method of bypassing the explicit modelling of the human kinematics.

Objective. This paper proposes machine learning models for mapping surface electromyography (sEMG) signals to regression of joint angle, velocity, acceleration, torque, and activation torque. Approach. The models, collectively known as MuscleNET, take one four forms: ANN (forward artificial neural network), RNN (recurrent CNN (convolutional RCNN convolutional network). Inspired by conventional ...

We present a kinematic study of a large sample of chromospherically active binaries (CAB) in order to determine their membership to representative young disk stellar kinematic groups: the Local Association (Pleiades moving group, 20-150 Myr), Ursa Mayor group (Sirius super-cluster, 300 Myr), Hyades supercluster (800 Myr), IC 2391 supercluster (35 Myr) and Castor moving group (200 Myr). Precise ...

Diffraction methods are at the heart of structure determination of solids. While Bragg-type scattering pure point diffraction is a characteristic feature of crystals and quasicrystals, it is not straightforward to interpret continuous diffraction intensities, which are generally linked to the presence of disorder. However, based on simple model systems, we demonstrate that it may be impossible ...

The kinematic filter is a common tool in control and signal processing applications dealing with position, velocity and other kinematical variables. Usually the filter gain is given a fixed value determined due to dynamic and measurement conditions. Most studies provide analytical solutions for optimal gains in particular scenarios. In practice, due to a lack of information (or under timevaryin...

Robotic hands differ in kinematics, dynamics, programming, control and sensing frameworks. Their common character is redundancy, which undoubtedly represents a key feature for dexterity and flexibility, but it is also a drawback for integrated automation since it typically requires additional efforts to seamlessly integrate devices, particularly robotic hands, in industrial scenario. This paper...

We prove that the mapping class group of a compact surface with a nite number of punctures and non-empty boundary is order automatic. More precisely, the group is right-orderable, has an automatic structure as described by Mosher, and there exists a nite state automaton that decides, given the Mosher normal forms of two elements of the group, which of them represents the larger element of the g...

The well-known finite-dimensional first-order open mapping theorem says that a continuous map with a finite-dimensional target is open at a point if its differential at that point exists and is surjective. An identical result, due to Graves, is true when the target is infinite-dimensional, if “differentiability” is replaced by “strict differentiability.” We prove general theorems in which the l...

More precisely, the group is right-orderable, has an automatic structure as described by Mosher, and there exists a finite state automaton that decides, given the Mosher normal forms of two elements of the group, which of them represents the larger element of t...
