Parametric Design of a Finger Rehabilitation Mechanism with Double Action and Two Degrees of Freedom
Applied Sciences, 2022 The objective of this work is to design a rehabilitation mechanism for the index finger that can replicate the finger’s natural movements in the sagittal plane; this mechanism must also be able to adapt to an individual’s anthropometric dimensions.

The Darboux theorem on plane trajectories of two-parametric space motions [PDF]
Applications of Mathematics, 1988 In dieser Arbeit wird eine vollständige Klassifikation der zweiparametrigen Bewegungen, bei denen mindestens fünf Punkte in Bahnebenen laufen, gegeben. Sie baut dabei wesentlich auf einer Arbeit von G. Darboux auf, in der neben einem expliziten Beispiel für eine solche Bewegung vor allem der Beweis dafür gegeben wird, daß bei einer derartigen Bewegung ...

Parametric Object Motion from Blur [PDF]
Computer Vision and Pattern Recognition, 2016 Motion blur can adversely affect a number of vision tasks, hence it is generally considered a nuisance. We instead treat motion blur as a useful signal that allows to compute the motion of objects from a single image.

A Contribution to Avalanche Dynamics: A Formal and an Exact Solution of the Voellmy/Perla Two-Parametric Equation of Motion (Abstract only) [PDF]
Annals of Glaciology, 1983 The two-parameter equation of motion for snow avalanches proposed by Voellmy in 1955 was later formally derived by Perla in 1979. It has been the object of numerous investigations, mainly to its applications. It has been solved for tracks approximated by straight lines, and this solution has, in some countries, been used extensively with a two-segment ...

On amplification of light in the continuous EPR state [PDF]
, 2003 Two schemes of amplification of two-mode squeezed light in the continuous variable EPR-state are considered. They are based on the integrals of motion, which allow conserving quantum correlations whereas the power of each mode may increase.

An Investigation of Harmonic Oscillation of an Ion Particle in a Non-uniform Electrostatic Field [PDF]
Journal of Electromagnetic Engineering and Science, 2023 In this study, we investigate the possibility to trap an ion particle in a non-uniform electrostatic field generated by two ionic rings, with the aim to obtain and verify general results regarding our proposition.

Dynamics of entanglement of a three-level atom in motion interacting with two coupled modes including parametric down conversion [PDF]
, 2014 In this paper, a model by which we study the interaction between a motional three-level atom and two-mode field injected simultaneously in a bichromatic cavity is considered; the three-level atom is assumed to be in a Λ-type configuration.

Local resonances and parametric level dynamics in the many-body localized phase [PDF]
Physical review B, 2021 By varying the disorder realisation in the many-body localised (MBL) phase, we investigate the influence of resonances on spectral properties. The standard theory of the MBL phase is based on the existence of local integrals of motion (LIOM), and ...

THE LOGARITHMIC SPIRAL AND ITS SPHERICAL COUNTERPART
Journal of Industrial Design and Engineering Graphics, 2020 Logarithmic spirals are isogonal trajectories of pencils of lines. From a series of geometric consequences, we pick out a few which are relevant for kinematics: When a logarithmic spiral rolls on a line, its asymptotic point traces a straight line. Hence,

MR-based motion correction for cardiac PET parametric imaging: a simulation study
EJNMMI Physics, 2018 Background Both cardiac and respiratory motions bias the kinetic parameters measured by dynamic PET. The aim of this study was to perform a realistic positron emission tomography-magnetic resonance (PET-MR) simulation study using 4D XCAT to evaluate the ...
