The two variable frequency oscillators track each other at frequencies 100 kHz apart. The output of a 0.5-250 MHz oscillator, [1] F1, is fed into a bridge. When the impedance network to be measured is connected one arm across the bridge, the equivalent parallel resistance and reactance (capacitive or inductive) unbalances the bridge and the resulting voltage is fed to the mixer.
This arrangement favors four- and eight-car trains in A–B–B–A and A–B–B–A–A–B–B–A configurations, but six-car trains in A–B–B–A–B–A and trains in any configuration are also in use. The following diagram depicts an eight-car train, with couplers represented by crosses and semi-permanent link bars represented by dashes.
The A650 is an electric multiple unit rapid transit (known locally as a subway) car built for use on the Los Angeles Metro Rail system. The cars were manufactured by the Italian company Breda at its Pistoia plant in Italy between 1988 and 1997 and are used on the Metro B and D Lines.
The FTSE 250 Index, also called the FTSE 250, or, informally, the "Footsie 250" / ˈ f ʊ t s i /, is a stock market index that measures the real strength of the economy of the United Kingdom [1] and consists of the 101st to the 350th mid-cap blue chip companies listed on the London Stock Exchange.
The Sd.Kfz. 250 (German: Sonderkraftfahrzeug 250; 'special motor vehicle') was a light armoured half-track, very similar in appearance to the larger Hanomag-designed Sd.Kfz. 251, and built by the DEMAG firm, for use by Nazi Germany in World War II.
2-opt. In optimization, 2-opt is a simple local search algorithm for solving the traveling salesman problem.The 2-opt algorithm was first proposed by Croes in 1958, [1] although the basic move had already been suggested by Flood. [2]
The name Pendolino is used to identify a family of high-speed, tilting-technology trains, produced in Italy.These trains owe their name (pendolino can mean "small pendulum" in Italian) to the mechanism enabling them to tilt when going around a curve.
Mahoney Lake Ecological Reserve. The Okanagan Country, also known as the Okanagan Valley, is a region located in the Canadian province of British Columbia and the U.S. state of Washington (where it is spelled the Okanogan Country), defined by the basin of Okanagan Lake and the Okanagan River.
