In his expedition account South, Shackleton gives a description of a Fata Morgana observed on 1915, coincidentally as his ship Endurance drifted close to the recorded position of New South Greenland: "The distant pack is thrown up into towering barrier-like cliffs, which are reflected in blue lakes and lanes of water at their base.
Bronson (1990 , 1994 recorded infants' gaze positions using an early corneal reflection-based device, replayed infants' recorded position of gaze (POG) onto a rear projection screen post hoc, and identified fixations by hand.
In order to provide a numerical description of the robots' behavior, chaotic measures are estimated on the attractor reconstructed from the recorded positions of the agent.
Computer-assisted recording and long-term analysis of movements were used to record positions of joints and body regions while performing certain tasks in terms of angular degrees of joints (ADJ) according to the neutral zero method.
Considering the sufficient sampling of Na+ ions within the SF in the equilibrium simulation, we recorded positions of all valid Na+ ions (staying in the SF for at least 1 ns) and then generated the 3D probability density map for these positions (Fig. 1E).
Considering the recorded positions of the 2-dimensional feature vector in Figure 2 and the corresponding contribution rate, together with our analysis, the following conclusion is obtained: the higher the redundancy of the data is, that is, the greater its correlation is, the smaller the corresponding concentration level is.
Multi-tracker was used for interfacing and recording positions of tested individuals [ 48, 49].
Eye movements were recorded using a Tobii 1750 eye tracker (Tobii Technology Inc., Stockholm, Sweden), which records the position of the eyes approximately every 20 ms (50 Hz).
The FeelTrace program records the position of the moving spot on the rating scale every 25ms giving a near continuous recording at a rate of 40Hz.
A roof-mounted GPS antenna records the position of the vehicle.
