The hills were covered with mist at frequent intervals, rendering observation from the air and visual signalling impossible.

This principle applies to all visual signalling.

Visual signalling, on which pains had been lavished during training, proved of little use.

At the right of the drop associated with the trunks are seven visual signals, these being the calling signals of the local lines.

In news:

Here we analyze visual signaling in populations of ganglion cells recorded from the isolated salamander retina .
Scientists have developed a dual technique that allows the simultaneous visualization of protein modifications and downstream mRNA production that occur as a result of cell signaling at the single-cell level.
Safety Integrity Level (SIL) audible and visual signaling devices are designed to conform to SIL 1 and SIL 2 safety requirements.
The low-profile SSPKWLP Series from Gentex Corporation of Zeeland, Michigan, is a line of speaker /strobes that offers dependable evacuation signaling and visual alarms.
They also include easyID local visual indication of surge module status and optional remote contact signaling integration with monitoring systems.
The system displays both percent of Total Polar Material and temperature on a bright backlit display as well as signals an audible and visual alarm when thresholds are exceeded.

Personal Memex can use various methods such as vibrations, haptic or tactile outputs, electronic signals, audio playback, and visual displays.
Human Information Processing with the Personal Memex
Note that, due to the high level of the noise (small amplitude of the signal with respect to the noise variance), it is difficult to detect visually the changes in the criterion behavior.
Estimation of the distribution of random shifts deformation
First developed by Kohonen (1995), the technique has subsequently found application to automatic speech recognition, analysis of electrical signals from the brain, data visualization and meteorology.
Interpreting self-organizing maps through space--time data models
We visually inspect the polarization maps to search for weak linear signals between two patches of circular polarization with opposite polarity.
Emergence of small-scale magnetic loops through the quiet solar atmosphere
In Secs. 2 and 3 we have treated incomplete delta functions in infnite dimensional spaces; here, in order to visualize better the finite dimensional case we will treat finite samples of signals with their finite Fourier transforms.
Incomplete Delta Functions
The result is presented on Fig. 7, from which it is seen that only the case phase = 3 provides nontrivial ordering leading to definite branches, that is we have clear visual presentation of the strong triplet signal.
Determinative degree and nucleotide sequence analysis by trianders
In the case of discrete AE, the time delay can visually be estimated from a marked jump in the burst of the AE signal, or can be instrumentally determined using a threshold function.

The rms intensity contrast of the granulation is about 7.5%, which represents the highest angular resolution ever obtained in spectropolarimetric studies of the quiet Sun. A visual inspection of the circular and linear polarization maps reveals a wealth of magnetic signals in the field of view (FOV).

However, to explore the possibility of an automated application, notwithstanding the information rendered by visual inspection of the plot K vs N in figure 5, it is necessary to determine the N dependence of the critical time series length N beyond which K correctly classifies the signal.
Probing Hamiltonian dynamics by means of the 0-1 test for chaos
For example, in a human being, the property of visual recognition allows specialized cells to process light signals from another ob ject to classify entities in the environment into different colors, sizes etc.
Organization and Complexity in a Nested Hierarchical Spin-Glass like Social Space
For example, the interconnection of the brain with the eyes and the ears enables the entire agent to respond to visual signals (how various ob jects within the environment interact with light) and auditory signals (vibration propagated through a medium within a certain range).

Recent studies such as confirmed that the retina is doing non-trivial operations to the input signal before transmission to the visual cortex.

The visual similarity between these independent maps therefore provides reassuring evidence that the bulk of the signal being detected is in fact due to temperature-fluctuations on the sky rather than unknown systematic problems.

This signal-to-noise level is adequate to portray an accurate overall visual impression of the anisotropy.

In this section we present visual results of using our estimator ˆθn to reconstruct various signals, given access only to smoothed and noisy, but repeated, observations of that signal.
