Many continuous wave navigational systems are not capable of independently resolving the integer number of wavelengths in a range measurement; the range is said to be ambiguous. The fractional part of the range can be measured but the integer must be initially given, and then tracked. If the number of ranges required to triangulate a fix exceeds the(More)
The treatment process described in this research explores the impact of exposing water samples containing fecal coliforms to the radiation produced by single ultraviolet (UV) light-emitting diodes (LEDs) operating at 265 nm. UV LEDs are long lasting, compact in size and produce more efficient light output than traditional mercury-vapour bulbs, making them(More)
