Converting was easy enough, and also inexpensive. Then, as today, you picked a vehicle shell hopefully light in weight and/or easy to modify added a motor, controller, and batteries, and went. Unfortunately, the most available motors in the appropriate size were decades-old war surplus aircraft starter DC motors; do-it-yourself controllers were barely more sophisticated than their turn-of-the-century counterparts; and battery technology, although cosmetically improved by modern manufacturing and packaging techniques, was virtually unchanged from 1900. As the most readily available controllers came from golf carts that typically used six 6-volt batteries (36 volts), and aircraft starter motors were typically rated at 24 to 48 volts, many first-time do-it-yourself EV attempts suffered from poor performance, and contemporary internal combustion muscle car owners of the 1960s just laughed at them. Then someone discovered motors were actually underrated to ensure long life, and began driving them at 72 to 96 volts. Some early owners found they could make simple, non-current-limiting controllers, and create vehicles that could easily embarrass any internal combustion muscle car at a stoplight. For a conceptual picture of this, imagine a subway traction motor in a dune buggy. In fact, these owners simply left the starting resistance out of a series DC motor, or equivalently diddled a shunt or compound motor. A series DC motor delivers peak torque at stall, and while starting currents were enormous, these early innovators just made sure they had a load attached when they switched on the juice. The immediate result was a rush. Predictably, the longer-term results were burned-out motors and, occasionally, broken drive shafts or axles. But the sanely driven and controlled 72- to 96-volt EV conversions were not bad at all. This was the 1960s, and the Electric Auto Association was founded in 1967.

To correctly create a complex join, select the join on CUST_ID and double-click it to bring up the Edit Join box. Use a CTRL-click to select the additional join relationships between the two tables. Alternatively, in the Expression box, type AND at the end of the join statement. As soon as you enter AND, Designer changes the join type to Complex. Your join should read

If we were radio listeners we might be familiar with the fact that there are different ways to indicate where to find a certain station on the radio dial. For example, we could say that a station is operating on 4250 kilohertz (kHz), 4.25 megahertz (MHz), or even on 71 meters. And all three ways would be correct! Radio waves are transmitted as a series of cycles, one after the other. The hertz, named in honor of the German physicist Hertz (abbreviated Hz), is equal to one cycle per second (cps). In fact, if you re as old as the author of this book, you might have used the term cps in your highschool physics classes instead of the more modern term Hz. If you were to visit the fuse box or circuit breakers in your home or apartment you might view a label that indicates the specification for the box or circuit breaker. In addition to telling you information about the amperes and voltage, if you reside in North America, you will also note a reference to the electric power being supplied to your home rated at 60 Hz. Electric power is distributed to your residence as alternating current (ac), meaning it goes through a cycle of changing directions of flow. When we say that electric power is 60 Hz, we mean it changes its direction of flow 60 times per second. Radio waves cycle more frequently than electricity resulting in such , waves going through far more cycles per second than electric current. Thus, we need to use bigger units to measure them. One such unit is the kilohertz (kHz), which is equal to 1000 cycles per second. Another commonly used unit is the megahertz (MHz), which is equal to 1,000,000 cycles per second, or 1000 kHz. The relationship between these units is shown below: 1,000,000 Hertz = 1000 kilohertz = 1 megahertz On the wonderful road to optical networking we began to use light, which requires even larger units for expression. This resulted in the use of the term gigahertz (GHz) for representing 1000 MHz. Thus another relation that warrants notice is:

In this example, you can see that a router s flash holds many files. Below the list of files, you can see how much flash is used (about 32MB), how much is available (about 32MB), and the total amount of flash on the router (64MB). You can also see how much flash you have installed on your IOS device with the show version command.

In an acid-base neutralization reaction, the hydronium (hydrogen) ions of the acidic solution react with the hydroxide ions in the basic solution. The reaction may be shown by this equation. H3O (aq) OH (aq) 0 H2O(l) Note that one mole of hydronium ions reacts with one mole of hydroxide ions. The solution is neutral when chemically equivalent amounts of acid and base are present. Indicators are chemical dyes that change color with a change of pH. Litmus paper and phenolphthalein are two common indicators used in acid-base reactions. They are chosen because they change color at or very near solution neutrality. Litmus paper is red in acidic solutions and blue in basic solutions. Phenolphthalein is colorless in acidic solutions and turns red in basic solutions.

All but one of these values is self-explanatory. The one that needs some explanation is ThreadState.WaitSleepJoin. A thread enters this state when it is waiting because of a call to Wait( ), Sleep( ), or Join( ).
