Warren P. Mason
Warren Perry Mason (September 28, 1900 – August 23, 1986) was an American electrical engineer and physicist at Bell Labs. A graduate of Columbia University, he had a prolific output, publishing four books and nearly a hundred papers. He was issued over two hundred patents, more than anyone else at Bell Labs. His work included acoustics, filters, crystals and ceramics, materials science, polymer chemistry, ultrasonics, bonding to semiconductors, internal friction, and viscoelasticity. Mason founded the field of distributed-element circuits. He was the first to experimentally show viscoelasticity in individual molecules. He found experimental evidence of electron-phonon coupling in solids and made measurements that aided the theories of phonon drag and superconductivity. Many of Mason's inventions in electronics are still widely used by modern circuit designers. Family and education Mason was born in Colorado Springs, Colorado, on September 28, 1900, to Kate Sagendorp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distributed-element Circuit
Distributed-element circuits are electrical circuits composed of lengths of transmission lines or other distributed components. These circuits perform the same functions as conventional circuits composed of passive components, such as capacitors, inductors, and transformers. They are used mostly at microwave frequencies, where conventional components are difficult (or impossible) to implement. Conventional circuits consist of individual components manufactured separately then connected together with a conducting medium. Distributed-element circuits are built by forming the medium itself into specific patterns. A major advantage of distributed-element circuits is that they can be produced cheaply as a printed circuit board for consumer products, such as satellite television. They are also made in coaxial and waveguide formats for applications such as radar, satellite communication, and microwave links. A phenomenon commonly used in distributed-element circuits is that a length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warren P Mason
A warren is a network of wild rodent or lagomorph, typically rabbit burrows. Domestic warrens are artificial, enclosed establishment of animal husbandry dedicated to the raising of rabbits for meat and fur. The term evolved from the medieval Anglo-Norman concept of free warren, which had been, essentially, the equivalent of a hunting license for a given woodland. Architecture of the domestic warren The cunicularia of the monasteries may have more closely resembled hutches or pens, than the open enclosures with specialized structures which the domestic warren eventually became. Such an enclosure or ''close'' was called a ''cony-garth'', or sometimes ''conegar'', ''coneygree'' or "bury" (from "burrow"). Moat and pale To keep the rabbits from escaping, domestic warrens were usually provided with a fairly substantive moat, or ditch filled with water. Rabbits generally do not swim and avoid water. A ''pale'', or fence, was provided to exclude predators. Pillow mounds The most ch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
School Principal
A head master, head instructor, bureaucrat, headmistress, head, chancellor, principal or school director (sometimes another title is used) is the staff member of a school with the greatest responsibility for the management of the school. In some English-speaking countries, the title for this role is '' principal.'' Description School principals are stewards of learning and managing supervisors of their schools.

A Deptford culture campsite existed in Gainesville and was estimated to have been used between 500 BCE and 100 CE. The Deptford people moved south into Paynes Prairie and Orange Lake during the first century and evolved into the Cades Pond culture. The Deptford people who remained in the Gainesville area were displaced by migrants from southern Georgia sometime in the seven ...

Acoustical Society Of America
The Acoustical Society of America (ASA) is an international scientific society founded in 1929 dedicated to generating, disseminating and promoting the knowledge of acoustics and its practical applications. The Society is primarily a voluntary organization of about 7500 members and attracts the interest, commitment, and service of many professionals. History In the summer of 1928, (See Wallace Clement Sabine.) Floyd R. Watson and Wallace Waterfall (1900–1974), a former doctoral student of Watson, were invited by UCLA's Vern Oliver Knudsen to an evening dinner at Knudsen's beach club in Santa Monica. The three physicists decided to form a society of acoustical engineers interested in architectural acoustics. In the early part of December 1928, Wallace Waterfall sent letters to sixteen people inquiring about the possibility of organizing such a society. Harvey Fletcher offered the use of the Bell Telephone Laboratories at 463 West Street in Manhattan as a meeting place for an ...

Research Associate
Research associates are researchers (scholars and professionals) that usually have an advanced degree beyond a Master's degree. In some universities/research institutes, such as Harvard/Harvard Medical School/Harvard School of Public Health, the candidate holds the degree of Ph.D. or possess training equivalent to that required for the Ph.D. In addition, the candidate must have demonstrated exceptional fitness in independent research. This position allows the candidate to enlarge professional network, get more experience, get publications, fellowships, grants to establish independence as a PI or start looking for a more secure permanent job. It can advance to Senior Research Associate (higher pay with more responsibilities equivalent to a PI), Research Scientist, Senior Research Scientist, Principal Research Scientist, and later Head of Research or equivalent.
