Ficus plant grown under a white LED grow light. A grow light is an electric light that can help plants grow. Grow lights either attempt to provide a light spectrum similar to that of the sun, or to provide a spectrum that is more tailored to the needs of the plants being cultivated (typically a varying combination of red and blue light, which generally appears pink to purple to the human eye).
The simulated growth of plants is a significant task in of systems biology and mathematical biology, which seeks to reproduce plant morphology with computer software. Electronic trees (e-trees) usually use L-systems to simulate growth. L-systems are very important in the field of complexity science and A-life.
The daily light integral (DLI) is the number of photosynthetically active photons (photons in the PAR range) accumulated in a square meter over the course of a day. It is a function of photosynthetic light intensity and duration (day length) and is usually expressed as moles of light (mol photons) per square meter (m −2) per day (d −1), or: mol·m −2 ·d −1.
This is a list of lighting design software for use in analyzing photometrics, BIM (Building Information Modeling), and 3D modeling. The software is typically used by importing the structural design via CAD files. Then lighting elements are inserted. And finally, the lighting objects are associated with a photometry via IES files.
Freeway Express appeared around the same time as version 3.5. It is a more entry level version of Freeway aimed at home users and priced accordingly compared to the Pro version. [ 12 ] Version 6 for Freeway Expres became the freeware version of Freeway Pro.
Revenue from software sales was $2.44 million in 2007 (no new version of NetObjects Fusion was released), down from $3.58 million in 2006 and $3.86 million in 2005. [ 6 ] [ 7 ] [ 8 ] NetObjects Fusion reached the biggest resonance in Germany , reaching nearly two-thirds of the market by the end of the 1990s. [ 9 ]
A freshwater aquatic food web. The blue arrows show a complete food chain (algae → daphnia → gizzard shad → largemouth bass → great blue heron). A food web is the natural interconnection of food chains and a graphical representation of what-eats-what in an ecological community.
Over time, software was created to help design web pages. For example, Microsoft released FrontPage in November 1995. By 1998, Dreamweaver had been established as the industry leader; however, some have criticized the quality of the code produced by such software as being overblown and reliant on HTML tables.
