The Aura project [11] incorporates a location module which, besides being able to handle multiple sources of positioning information, is also structured to protect access to people's location [13].
Dr Thomas added: "We concluded that the UK was already dangerously dependent on GPS as a single source of position, navigation and timing (PNT) data.
In unrelated transgenic mouse experiments, the expanded GAA triplet-repeat sequence was found to be a source of position effect variegation (PEV) i.e., a source of heterochromatin spreading into adjacent euchromatin [5].
On the other hand, the backlash is the main source of positioning error and impact.
Airflow is the main source of positioning error in outdoor environments, so a strategy based on a differential emitter fixed at a known position is used, which permits to cancel out the effects of uniform air motion.
The vibrations of the mechanical parts of the system and particularly the vibrations of the thin carbon wire have been identified as the major error sources of wire position uncertainty.
Now there are five sources of influence Position, Knowledge/Expertise, Network, Character, and Success.
Possible sources of eye position information can include proprioceptive feedback from ocular muscles and motor efference copy [59], [60].
43 In the current study, subjects actively moved the matching arm in the vertical plane during the position matching test to match the reference arm; therefore, the source of the position signal in the matching arm was a combination of inflow and outflow signals.
Takai et al. [4] proposed a skeleton cube as a reference object that creates a self cast shadows from a point light source of arbitrary position.
