consideration is whether the new HDTV standard should be compatible with the existing color TV standards‚ supplant the existing standards‚ or be simultaneously broadcast with the existing standards (with the understanding that the existing standards would be faded out over time). There is precedence for both compatibility and simultaneous broadcast. In 1957‚ the US chose compatibility when

Hyperbolic navigation Hyperbolic navigation refers to a class of radio navigation systems based on the difference in timing between the reception of two signals‚ without reference to a common clock. This timing reveals the difference in distance from the receiver to the two stations. Plotting all of the potential locations of the receiver for the measured delay produces a series of hyperbolic lines on a chart. Taking two such measurements and looking for the intersections of the hyperbolic lines

The use of forensic science improved investigating policing over the years because things like fingerprinting‚ radios‚ discovery of DNA evidence and CCTV was all introduced in the 1900s. Fingerprinting Fingerprinting is used to take fingerprints of people and can later be used to identify people by a distinctive mark or characteristic. Fingerprinting is useful as it helps to identify victims or criminals quickly and accurately. Fingerprinting is very useful in forensic science as fingerprints

time-synchronized using a separate GPS receiver‚ and our data was later correlated with that acquired at a nearby wired sensor array. In addition to continuous sampling‚ we have developed a distributed event detector that automatically triggers data transmission when a well-correlated signal is received by multiple nodes. We evaluate this approach in terms of reduced energy and bandwidth usage‚ as well as accuracy of infrasonic signal detection. I. I NTRODUCTION Wireless sensor networks have the potential

light output in the range 30 - 60 nm. In view of this the signal will be subject to chromatic dispersion‚ and this will limit the distances over which data can be transmitted It is also found that the light emitted for a LED is not particularly directional and this means that it is only possible to couple them to multimode fibre‚ and even then the overall efficiency is low because not allt he light can be coupled into the fibre optic cable. LEDs have significant advantages as fibre optic transmitters
