For a real number x and an integer n ≥ 0, let [x] n denote the (finite) decimal expansion of the greatest number that is not greater than x that has exactly n digits after the decimal mark. Let d i denote the last digit of [x] i. It is straightforward to see that [x] n may be obtained by appending d n to the right of [x] n−1. This way one has
is the smallest closed set containing at least three points which is completely invariant under f. is the closure of the set of repelling periodic points. For all but at most two points , the Julia set is the set of limit points of the full backwards orbit (). (This suggests a simple algorithm for plotting Julia sets, see below.)
This computation accounts for the well-to-wall losses resulting from the extraction of crude oil and refinement into gasoline (T p), conversion to electricity (T g), and the transmission grid (T t); in summary, the total amount of useful electrical energy that can be extracted from gasoline is just 36.5% of its total theoretical stored energy.

At the low range of capacity factors is the photovoltaic power station, which supplies power to the electricity grid from a large-scale photovoltaic system (PV system). An inherent limit to its capacity factor comes from its requirement of daylight , preferably with a sun unobstructed by clouds, smoke or smog , shade from trees and building ...
A pendulum with a period of 2.8 s and a frequency of 0.36 Hz. For cyclical phenomena such as oscillations, waves, or for examples of simple harmonic motion, the term frequency is defined as the number of cycles or repetitions per unit of time.
While modern firearms are generally referred to by the name of the cartridge the gun is chambered for, they are still categorized together based on bore diameter. [citation needed] For example, a firearm might be described as a "30 caliber rifle", which could accommodate any of a wide range of cartridges using a roughly 0.30 inches (7.6 mm) projectile; or as a "22 rimfire", referring to any ...
Aluminium is widely used in sheet metal form due to its flexibility, wide range of options, cost effectiveness, and other properties. [6] The four most common aluminium grades available as sheet metal are 1100-H14, 3003-H14, 5052-H32, and 6061-T6.
Though California was now under the jurisdiction of the United States, land grants were allowed to continue in the form of private property. [18] In 1873, the United States Army built a telegraph line between San Diego and Fort Yuma which ran through Telegraph Canyon in Chula Vista; [ 21 ] [ 22 ] its construction was under the command of ...
