What is the CFL criterion and how does it determine the stability of numerical methods?
The CFL criterion is a rule used to determine the stability of numerical methods in solving partial differential equations. It stands for Courant-Friedrichs-Lewy criterion. It states that the product of the time step and the speed of the wave in the system must be less than a certain value for the method to be stable. If this condition is not met, the method may produce inaccurate or unstable results.
What are the CFL conditions for growing healthy and vibrant plants indoors?
To grow healthy plants indoors using CFL lights, you need to ensure the lights are placed close to the plants (2-4 inches away), provide 12-16 hours of light per day, and use bulbs with a color temperature of 6500K for vegetative growth and 2700K for flowering. Additionally, make sure to rotate the plants regularly to ensure even light distribution and consider supplementing with natural light if possible.
What display is used for portable computers and other applications where weight and space considerations are critical?
An LCD display or nowadays OLED Display ( Cathode ray tube a physically too heavy due to lead glass and consume any where between 80 - 120 watts of power) LCD use a filter crystal matrix in the display for each colour (Red Green Blue) to filter light in each pixel from a CFL or led backlight
