Motion in gauge theories of gravity

, 2012
A description of motion is proposed, adapted to the composite bundle interpretation of Poincar\'e Gauge Theory. Reference frames, relative positions and time evolution are characterized in gauge-theoretical terms.

The Relativistic N-body Problem in a Separable Two-Body Basis

, 2000
We use Dirac's constraint dynamics to obtain a Hamiltonian formulation of the relativistic N-body problem in a separable two-body basis in which the particles interact pair-wise through scalar and vector interactions.

Improvements of the Inverse Compositional Algorithm for Parametric Motion Estimation [PDF]

Image Processing On Line, 2018
In this work, we propose several improvements of the inverse compositional algorithm for parametric registration. We propose an improved handling of boundary pixels, a different color handling and gradient estimation, and the possibility to skip scales in the multiscale coarse-to-fine scheme.

Study on graphite motion law of copper-based graphite composites during friction

Journal of Advanced Mechanical Design, Systems, and Manufacturing
To analyze self-lubricating mechanism of copper-based graphite composites, the discrete element method (DEM) was used to study motion law of graphite particles of copper-based graphite composite/45 steel during friction.

Towing Motion Characteristics of Composite Bucket Foundation for Offshore Wind Turbines

Energies, 2019
Composite bucket foundation (CBF) is an environmentally friendly form of offshore wind power foundation. By virtue of the air-floating subdivision structure in the bucket, the foundation has a self-floating characteristic and can allow for long-distance ...

Composite Fermion Metals from Dyon Black Holes and S-Duality

, 2010
We propose that string theory in the background of dyon black holes in four-dimensional anti-de Sitter spacetime is holographic dual to conformally invariant composite Dirac fermion metal.

Pulmonary Dysfunction Is Associated With Sleep Study Abnormalities in Children With Sickle Cell Disease: A Multicenter Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Pulmonary dysfunction and sleep abnormalities are common in children with sickle cell disease (SCD) and are associated with worse clinical outcomes. Whether spirometry abnormalities are associated with polysomnography (PSG) findings remains unclear.

Fast and Intelligent Proportional–Integral–Derivative (PID) Attitude Control of Quadrotor and Dual-Rotor Coaxial Unmanned Aerial Vehicles (UAVs) Based on All-True Composite Motion

Drones
The construction of a six-degree-of-freedom (6-DOF) model for the composite motion of the actual mechanical structure (defined as an all-true composite motion model) of unmanned aerial vehicles (UAVs) is a prerequisite for achieving stable control of ...
