Nutation and Reference Frame [PDF]
Highlights of Astronomy, 1995 The reference frames are of fundamental importance in all kinds of the precession and nutation studies involving the theory, the coordinate transformation and the observations. The aim of this paper is to review all the frames used in such studies and to lead to a better consistency between them in order that theory and reductions of observations be ...

A persistent prefrontal reference frame across time and task rules. [PDF]
Nat CommunBehavior can be remarkably consistent, even over extended time periods, yet whether this is reflected in stable or 'drifting' neuronal responses to task features remains controversial. Here, we find a persistently active ensemble of neurons in the medial

From line to dots: an improved computerised rod and frame system for testing subjective visual vertical and horizontal [PDF]
, 2010 Background Perception of subjective visual vertical (SVV) and horizontal (SVH) has traditionally been measured by rotating a mechanical rod either with or without a frame present. The computerised rod and frame (CRAF) system has previously only been used

Frontiers in Integrative Neuroscience, 2011 The motor layers of the superior colliculus (SC) are thought to specify saccade amplitude and direction, independent of initial eye position. However, recent evidence suggests that eye position can modulate the level of activity of SC motor neurons.

Characterizing the Dynamic Response of a Chassis Frame in a Heavy-Duty Dump Vehicle based on an Improved Stochastic System Identification [PDF]
, 2015 This paper presents an online method for the assessment of the dynamic performance of the chassis frame in a heavy-duty dump truck based on a novel stochastic subspace identification (SSI) method. It introduces the use of an average correlation signal as

Different roles of alpha and beta band oscillations in sensorimotor gating
Frontiers in Human Neuroscience, 2014 Alpha (8-12Hz) and beta band (18-30Hz) oscillations have been implicated in sensory anticipation and motor preparation. Here, using magneto-encephalography, we tested whether they have distinct functional roles in a saccade task that induces a remapping ...

Reference frame integration in spatial collaboration [PDF]
, 2023 Based on the previous studies, this study created a spatial collaboration situation, intended to explore how individuals establish spatial reference frame and explore the psychological mechanism of individuals' integration of spatial reference frame in ...

Recherches Sociologiques et Anthropologiques, 2013 The goal of this article is to show how, from a simple concept, “active ageing” was gradually transformed into an international frame of reference in public policies on the subject of ageing.

Reduced Reference Frame Transformation Assessment in Unbalanced Three-Phase Four-Wire Systems
IEEE Access, 2023 Three-phase four-wire systems require a reference frame similar to that used in 3-phase 3-wire system configurations that allow them to be easily analysed, modelled and controlled.
