voltage standing wave ratio (VSWR) - permalink - collapse

All > Technology > Telecommunications

In a transmission line, the ratio of maximum to minimum voltage in a standing wave pattern. Note: The VSWR is a measure of impedance mismatch between the transmission line and its load. The higher the VSWR, the greater the mismatch. The minimum VSWR, i.e., that which corresponds to a perfect impedance match, is unity.

All > Technology > Telecommunications

In alternating-current power transmission and distribution, the product of the rms voltage and amperage, i.e., the apparent power, multiplied by the sine of the phase angle between the voltage and the current. Note 1: Vars represents the power not consumed by a reactive load, i.e., when there is a phase difference between the applied voltage and the current. Note 2: Only effective power, i.e., the actual power delivered to or consumed by the load, is expressed in watts. Volt-amperes reactive is properly expressed only in volt-amperes, never watts. Note 3: To maximize transmission efficiency, vars must be minimized by balancing capacitive and inductive loads, or by the addition of an appropriate capacitive or inductive reactance to the load.

volume - permalink - collapse

All > Business > Finance > Personal Finance

Volume is the number of shares traded in a company's stock or in an entire market over a specified period, typically a day.
Unusual market activity, either higher or lower than average, is typically the result of some external event. But unusual activity in an individual stock reflects new information about that stock or the stock's sector.

Volume of Concrete - permalink - collapse

All > Science > Water

The total space occupied by concrete forming the dam structure computed between abutments and from the top to the bottom of the dam. No deduction is made for small openings such as galleries, adits, tunnels, and operating chambers within the dam structure. The volume includes all mass concrete appurtenances not separated from the dam by construction or contraction joints. Where a powerplant is located at the downstream toe of a concrete dam, the limit of concrete in the dam should be taken as the downstream face projected to the general excavated foundation surface.
