A Unified Global Reference Frame of Vertical Crustal Movements by Satellite Laser Ranging
Sensors, 2016 Crustal movement is one of the main factors influencing the change of the Earth system, especially in its vertical direction, which affects people’s daily life through the frequent occurrence of earthquakes, geological disasters, and so on.

Blazars define a stable celestial reference frame
Astronomy & AstrophysicsContext. Recent work has shown that optical-radio position offsets and radio position variability are inversely correlated with the optical photometric variability of active galactic nuclei (AGN).

Frame-Free Continuum Thermomechanics [PDF]
, 2018 The principle of material frame-indifference is a fundamental concept in classical physics. In 1972 Walter Noll showed that one can formulate constitutive laws without using any external frames of reference.

Concept of spatial coordinate systems, their defining and implementation as a precondition in geospatial applications [PDF]
Glasnik Srpskog Geografskog Društva, 2015 There are many users of spatial information, and quite large interest about the nature and genesis of such information. Different users found spatial information in the form of maps, plans or alphanumerical tables. Recently, there are more often

Motion compensation reference frame compression [PDF]
, 2020 In a video encoder (100), a motion estimation module (102) identifies for a portion of a frame to be encoded, a similar portion in a reference frame. The reference frame is a decoded version of an already encoded frame.

Two Degree of Freedom Resonant Structure for Robust Current Control and Active Power Filtering [PDF]
, 2005 This paper introduces a novel two degree of freedom resonant control structure for current control in a stationary reference frame in one- or three-phase power electronics systems. The main focus is put on the design of the controller for robust tracking

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.
