Wait-free shared-memory irradiance caching [PDF]

open access: yes, 2011
Parallelizing rendering algorithms to exploit multiprocessor and multicore machines isn't straightforward. Certain methods require frequent synchronization among threads to obtain benefits similar to the sequential algorithm.

Outdoor Inclined Plastic Column Photobioreactor: Growth, and Biochemicals Response of Arthrospira platensis Culture on Daily Solar Irradiance in a Tropical Place

open access: yesMetabolites, 2022
Implementation of outdoor photobioreactors has been challenged by an extremely oversaturated daily peak of solar irradiance. This study aims to understand the role of column size and paranet shading as well as to investigate the most convenient light ...

Effects of sucrose and irradiance on germination and early gametophyte growth of the endangered tree fern Dicksonia sellowiana Hook (Dicksoniaceae) Efeito da sacarose e irradiância na germinação e crescimento inicial do gametófito da samambaia arbórea Dicksonia sellowiana Hook (Dicksoniaceae) em perigo de extinção

open access: yesActa Botânica Brasílica, 2004
It is an endangered tree fern that grows in mixed umbrophylus forests in the tropics. Sterilized spores were germinated at 25 ± 2ºC under a 16-hour photoperiod, in Dyer and MS medium supplemented with 0 to 5% sucrose.

Comparison of Decadal Trends among Total Solar Irradiance Composites of Satellite Observations

open access: yesAdvances in Astronomy, 2019
We present a new analysis of the two-decade-old controversy over interpretation of satellite observations of total solar irradiance (TSI) since 1978 and the implications of our findings for TSI as a driver of climate change.

Shortwave Radiance to Irradiance Conversion for Earth Radiation Budget Satellite Observations: A Review

open access: yesRemote Sensing, 2021
Observing the Earth radiation budget (ERB) from satellites is crucial for monitoring and understanding Earth’s climate. One of the major challenges for ERB observations, particularly for reflected shortwave radiation, is the conversion of the measured ...

Irradiance gradients

open access: yesACM SIGGRAPH 2008 classes, 2008
A new method for improving the accuracy of a diffuse interreflection calculation is introduced in a ray tracing context. The information from a hemispherical sampling of the luminous environment is interpreted in a new way to predict the change in irradiance as a function of position and surface orientation.
