Book Description
The report is intended to serve as a reference work for all those concerned with the selection, specifications, and use of signal * -light colors.It discusses the nature of the problem, and the mathematical representation, recognition, production, control, and use of such colors.The characteristics of different types of chromaticity boundaries and the purpose and effect of the requirement for similarity of chromaticity characteristics are given special consideration.The treatment is varied according to the intended use.The discussion of the control of colors and the section on the use of colors are nontechnical, whereas the section on the production of signal colors is designed for the colorimetrist who is faced with the problem of selecting limit filters or drafting a specification.(Author).

Book Description
“One of the best thrillers you'll read this year.”—Lee Child, #1 New York Times bestselling author No one knows what CIA desk jockey Zac Miller is capable of—including himself—until a routine surveillance job becomes a do-or-die mission in the Middle East. When a commercial flight violates restricted airspace to make an emergency landing at a closed airport in Iran, the passengers are just happy to be alive and ready to transfer to a functional plane. All of them except one... The American technology consultant in business class is not who he says he is. Zac Miller is a CIA analyst. And after an agent's cover gets blown, Zac—though never trained to be a field operative—volunteers to take his place, to keep a surveillance mission from being scrubbed. Zac thinks it will be easy to photograph the earthquake-ravaged airport that is located near a hidden top secret nuclear facility. But when everything that can go wrong does, he finds himself on the run from the Islamic Revolutionary Guards and abandoned by his own teammates, who think he has gone rogue. Embarking on a harrowing journey through the mountains of Iran to the Persian Gulf and across Europe, Zac can only rely on himself. But even if he makes it out alive, the life he once had may be lost to him forever...

Curves of Input Impedance Change Due to Ground for Dipole Antennas

Curves of Input Impedance Change Due to Ground for Dipole Antennas PDF Author: Lewis E. Vogler
Publisher:
ISBN:
Category : Antennas (Electronics).
Languages : en
Pages : 368

Book Description
Graphs of the change in input impedance of electrically short dipole antennas in the presence of an isotropic and homogeneous ground are presented, considering four types of antennas: horizontal and vertical, electric and magnetic dipoles.Curves of the change in both the input resistance and reactance are shown for a wide range of values of the frequency, antenna height above the ground, and electromagnetic ground constants.(Author).
