Frederick B. Llewellyn
Frederick Britton Llewellyn (September 16, 1897 - December 10, 1971) was a noted American electrical engineer. Llewellyn was born in New Orleans, Louisiana. He took a course at the Marconi School for Wireless Operators in 1915, spent some three years in the merchant marine, and almost a year in the Navy in 1917-18. He then studied under Professor Alan Hazeltine at Stevens Institute of Technology, receiving his M.E. degree in 1922. After a year as laboratory assistant to Dr. F. K. Vreeland, he joined Western Electric in 1923, transferring in 1925 to Bell Telephone Laboratories, where he worked on the long-wave transatlantic telephone based in Rocky Point, New York. From 1924-28 he studied at Columbia University, receiving his Ph.D in 1928. Llewellyn helped develop the first public ship-to-shore telephone service, inaugurated in 1929 on the SS Leviathan. In the 1930s he studied noise in vacuum tubes and constant-frequency oscillators, and researched the behavior of vacuum tubes ...

Electrical Engineer
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrica ...

Project Diana
Project Diana, named for the Roman moon goddess Diana, was an experimental project of the US Army Signal Corps in 1946 to bounce radar signals off the Moon and receive the reflected signals. This was the first experiment in radar astronomy and the first active attempt to probe another celestial body. It was the inspiration for later EME (Earth-Moon-Earth) communication techniques. History Following the end of World War II, Col. John H. DeWitt Jr., Director of the Evans Signal Laboratory at Camp Evans (part of Fort Monmouth), in Wall Township, New Jersey, was directed by the Pentagon to determine whether the ionosphere could be penetrated by radar, in order to detect and track enemy ballistic missiles that might enter the ionosphere. He decided to address this charge by attempting to bounce radar waves off the moon. For this task he assembled a team of engineers that included Chief Scientist E. King Stodola, Herbert Kauffman, Jacob Mofenson, and Harold Webb. Input from oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Michigan Faculty
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

People From New Orleans
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...
