diurnal
Art History
(adjective)
Happening or occurring during daylight, or primarily active during that time.
Physics
Examples of diurnal in the following topics:
-
Introduction to the Fourier Series
- So buried in the time-series on the top you would expect to see two dominant frequencies, one that was diurnal (1 cycle per day) and one that was semi-diurnal (2 cycles per day).
- You'll notice in the tiltmeter spectrum that the two peaks (diurnal and semi-diurnal seem to be split; i.e., there are actually two peaks centered on 1 cycle/day and two peaks centered on 2 cycles/day.
- Given what we know about the physics of tilt, we should expect that the diurnal tide (once per day) should peak at 1 cycle per day, while the semi-diurnal tide (twice per day) should peak at 2 cycles per day.
-
Tides
- Shorelines where two almost equally high tides and two low tides occur each day experience a semi-diurnal tide.
- The occurrence of only one high and one low tide each day is known as diurnal tide.
-
Dimensions of Human Development
- At first, this sleep is evenly spread throughout the day and night but after a couple of months, infants generally become diurnal.
-
Non-Native Hawaiian Art
- Some of the artists also produced watercolors, which, by the nature of the medium, tended to be diurnal.
-
Malabsorption of Nutrients
- Diarrhea (watery, diurnal and nocturnal, bulky, frequent stools) is the clinical hallmark of overt malabsorption.
-
Characteristics and Evolution of Primates
- In general, prosimians tend to be nocturnal (in contrast to diurnal anthropoids, excluding the nocturnal Aotus, owl monkey) and have a smaller brain/body ratio than anthropoids.
