Detection of Harmful Algal Blooms
Detection of Harmful Algal Blooms

... A hazardous algal bloom occurs when a sudden increase of nutrients in large bodies of water leads to a rapid growth of first-order organisms that can cause harm to their environment, e.g. the release of the toxin microcystin. Our plan is to create a remote sensing node that will monitor for the pres ...

Electrical ballast



An electrical ballast is a device intended to limit the amount of current in an electric circuit. A familiar and widely used example is the inductive ballast used in fluorescent lamps, to limit the current through the tube, which would otherwise rise to destructive levels due to the tube's negative resistance characteristic.Ballasts vary in design complexity. They can be as simple as a series resistor or inductor, capacitors, or a combination thereof or as complex as electronic ballasts used with fluorescent lamps and high-intensity discharge lamps.
