Inertial Sensor-Based Lower Limb Joint Kinematics: A Methodological Systematic Review

open access: yesItalian National Conference on Sensors, 2020
The use of inertial measurement units (IMUs) has gained popularity for the estimation of lower limb kinematics. However, implementations in clinical practice are still lacking. The aim of this review is twofold—to evaluate the methodological requirements

Scattering forms and the positive geometry of kinematics, color and the worldsheet [PDF]

open access: yes, 2017
A bstractThe search for a theory of the S-Matrix over the past five decades has revealed surprising geometric structures underlying scattering amplitudes ranging from the string worldsheet to the amplituhedron, but these are all geometries in auxiliary ...

Structure and Kinematics of Early-Type Galaxies from Integral Field Spectroscopy [PDF]

open access: yes, 2016
Observations of galaxy isophotes, long-slit kinematics, and high-resolution photometry suggested a possible dichotomy between two distinct classes of elliptical galaxies. But these methods are expensive for large galaxy samples.

A speedup method for solving the inverse kinematics problem of robotic manipulators

open access: yesInternational Journal of Advanced Robotic Systems, 2022
The inverse kinematics problem involves the study that the inverse kinematics solver needs to calculate the values of the joint variables given the desired pose of the end-effector of a robot.

Finite-Time Convergence Adaptive Fuzzy Control for Dual-Arm Robot With Unknown Kinematics and Dynamics

open access: yesIEEE transactions on fuzzy systems, 2019
Due to strongly coupled nonlinearities of the grasped dual-arm robot and the internal forces generated by grasped objects, the dual-arm robot control with uncertain kinematics and dynamics raises a challenging problem.

Born–Infeld Kinematics [PDF]

open access: yesAnnals of Physics, 2002
We encode dynamical symmetries of Born-Infeld theory in a geometry on the tangent bundle of generally curved spacetime manifolds. The resulting covariant formulation of a maximal acceleration extension of special and general relativity is put to use in the discussion of particular point particle dynamics and the transition to a first quantized theory.
