tide, any of the cyclic deformations of one astronomical body caused by the gravitational forces exerted by others. The most familiar are the periodic variations insea levelonEarththat correspond to changes in the relative positions of theMoonand theSun. The tides may be regarded as forcedwaves,...
Dredging is the periodic manual removal of sediment to keep channels open for navigation. In some estuaries, dredging is controversial because it may have negative effects on the biota (living plants and animals). Once the sediment is dredged, it is usually deposited nearby in specially designeddi...
“Coupon” refers to a periodic interest payment, so zero-coupon means there are no interest payments during the CD term. For example, if you bought a 10-year, $100,000 CD for $85,000, you wouldn’t receive interest payments during the CD term. Instead, you’d receive the $100,000...

Observium is best suited for medium to large networks. The paid version provides periodic notifications. Observium has both a free Community edition and commercial subscriptions. For open-source enthusiasts, LibreNMS, a fork of Observium’s last GPL-licensed version, is available. ...
sin x describes the ratio of a right triangle's opposite side to its hypotenuse for an angle of measure x. Trigonometric functions are distinct in that they are periodic, meaning the graph repeats after a certain amount of time. The graph of a standard sine wave has a period of 360 ...

If considering one of these antennas, the initial overall performance and gain can be good, but over time their performance may deteriorate more than others if the mechanical arrangements start to fail.Log periodic antennaThe log periodic antenna may look a little like a Yagi...
A more formal definition (for those interested) would be –"The periodic short term changes in the height of the ocean surface at a particular place." So what causes this rise and fall of sea levels? Most people have been taught that the tides are the result of the moon’s gravitational...
As a widely available natural resource, plant fibers are economical and have a good resistance to rain, although they can be easily attacked by biological agents or by strong winds. Similar to wood, they require periodic maintenance because they degrade rapidly and present a fire ha...
