Measuring overcast colors with all-sky imaging.
Digital images of overcast skies as seen from the earth's surface open new windows onto the angular details of overcast colors and visible-wavelength spectra. After calibration with a spectroradiometer, a commercial CCD camera equipped with a fisheye lens can produce colorimetrically accurate all-sky maps of overcast spectra. Histograms and azimuthally averaged curves of the resulting chromatic...
متن کاملMeasuring Wind Plant Capacity Value
Electric utility planners and wind energy researchers pose a common question: What is the capacity value of a wind plant? Tentative answers, which can be phrased in a variety of ways, are based on widely varying definitions and methods of calculation. From the utility's point of view, a resource that has no capacity value also has a reduced economic value. Utility planners must be able to quant...
متن کاملSurvey of Plant Pigments: Molecular and Environmental Determinants of Plant Colors
It is difficult to estimate the importance of plant pigments in plant biology. Chlorophylls are the most important pigments, as they are required for photosynthesis. Carotenoids are also necessary for their functions in photosynthesis. Other plant pigments such as flavonoids play a crucial role in the interaction between plants and animals as visual signals for pollination and seed scattering. ...
متن کاملLuminance contours can gate afterimage colors and "real" colors.
It has long been known that colored images may elicit afterimages in complementary colors. We have already shown (Van Lier, Vergeer, & Anstis, 2009) that one and the same adapting image may result in different afterimage colors, depending on the test contours presented after the colored image. The color of the afterimage depends on two adapting colors, those both inside and outside the test. He...
متن کاملThe Inheritance of Virescent Yellow and Red Plant Colors in Cotton.
Deficiencies in the amount of chlorophyll in the cotton plant have been reported in relatively few instances. BALLS (1908) made a cross between an upland cotton with light green leaves and a dark green Egyptian cotton. He states that in the Fz generation, plants with light green leaves and plants with dark green leaves appeared in a 3 : 1 ratio. STROMAN and MAHONEY (1925) recovered two chloroph...
