Disk brakes or sawing processes represent complicated thermo-mechanical systems where the dynamic interaction of the different components involved including heat effects establish a physical problem very interesting for theory and practical applications. In both cases the main structural element is a rotating disk where heat and mechanical loads are induced via frictional or cutting force conta...

To calculate the RDF, for each time frame we used the centers of the neurofilaments in the domain [−0.2μm, 0.2μm] × [−0.2μm, 0.2μm] as reference points. We chose to use reference points in a smaller domain in order to avoid boundary effects. For each reference point we binned the center-to-center distances (r) between the reference neurofilament and all other neurofilaments with a bin size ∆r =...

Recent blood oxygenation level-dependent (BOLD) imaging work has suggested flexible coding frames for reach targets in human posterior parietal cortex, with a gaze-centered reference frame for visually guided reaches and a body-centered frame for proprioceptive reaches. However, BOLD activity, which reflects overall population activity, is insensitive to heterogeneous responses at the neuronal ...

This paper presents an algorithm for the efficient numerical analysis and simulation of modest to heavily constrained multi-rigid-body dynamic systems. The algorithm can accommodate the spatial motion of general multi-rigid-body systems containing arbitrarily many closed loops in O(n+m) operations overall for systems containing n generalized coordinates, and m independent algebraic constraints....

The aim of this study was to further understand how the brain represents spatial information for shaping aiming movements to targets. Both behavioral and neurophysiological studies have shown that the brain represents spatial memory for reaching targets in an eye-fixed frame. To date, these studies have only shown how the brain stores and updates target locations for generating a single arm mov...

Reaching to a location in space is supported by a cortical network that operates in a variety of reference frames. Computational models and recent fMRI evidence suggest that this diversity originates from neuronal populations dynamically shifting between reference frames as a function of task demands and sensory modality. In this human fMRI study, we extend this framework to nonmanipulative gra...

ABSTRACT Equations of fully general relativistic radiation hydrodynamics around a rotating black hole are derived by using the Kerr-Schild coordinate where there is no coordinate singularity at the event horizon. Since the radiation interacts with matter moving with relativistic velocities near the event horizon, the interplay between the radiation and the matter should be described fully relat...

Abstract: An optimal reconfiguration control for satellites formation flying with attitude constraints by the use of a small number of thrusters is addressed. These thrusters are fixed to the satellite body and generate unilateral forces. This study assumes that the satellite’s attitude angle during the reconfiguration maneuver is restricted within a certain bound from a specified direction in ...
