Like the radius function, it is piecewise sinusoidal.
They found that receptive-field parameters derived from edge contrast reversal were similar to those obtained using sinusoidal stimuli.
Speech analysis synthesis based on a sinusoidal representation.
These geometrically regular cells of hypodermis strongly contrasted the epidermis, composed of smaller cells with sinusoidal anticlinal walls.
These were determined using a circular patch of drifting sinusoidal grating of modest contrast.
Musical sound signal analysis/synthesis: sinusoidal-plus-residual and elementary waveform models.
The 'breaking' of the waves is therefore associated with the formation of a flow separation on the downstream face of sinusoidal wave.
In the present context, it seems unclear whether these models would respond appropriately to sinusoidal contrast modulation stimuli, which lack well-defined terminations or corners.
