Immediate treatment of heat stroke is body cooling; currently the preferred method of cooling is evaporation cooling by spraying the patient with cold water or covering them with cold water soaked sheets, and using fans to augment evaporative cooling.
Orthogonal Frequency Division Multiplexing or OFDM is a modulation format that is being used for many of the latest wireless and telecommunications standards. OFDM has been adopted in the Wi-Fi arena where the standards like 802.11a, 802.11n, 802.11ac and more.
For the radio station, see DWDM-FM. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light.t this stage, a basic DWDM system contains several main components: 1  A DWDM terminal multiplexer. 2  An intermediate line repeater is placed approximately every 80â100 km to compensate for the loss of optical power as the signal travels along the fiber. 3  An intermediate optical terminal, or optical add-drop multiplexer. 4  A DWDM terminal demultiplexer. 5  O
