Aeroacoustics
Aeroacoustics is a branch of acoustics that studies noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces. Noise generation can also be associated with periodically varying flows. A notable example of this phenomenon is the Aeolian tones produced by wind blowing over fixed objects. Although no complete scientific theory of the generation of noise by aerodynamic flows has been established, most practical aeroacoustic analysis relies upon the so-called ''aeroacoustic analogy'', proposed by Sir James Lighthill in the 1950s while at the University of Manchester. whereby the governing equations of motion of the fluid are coerced into a form reminiscent of the wave equation of "classical" (i.e. linear) acoustics in the left-hand side with the remaining terms as sources in the right-hand side. History The modern discipline of aeroacoustics can be said to have originated with the first publication of Lighthill in the early 1950s, when noise ge ...

Roadway Noise
Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. In developed and developing countries, roadway noise contributes a proportionately large share of the total societal noise pollution. In the U.S., it contributes more to environmental noise exposure than any other noise source. History Roadway noise began to be measured in a widespread manner in the 1960s, as computer modeling of this phenomenon began to become meaningful. After passage of the National Environmental Policy Act and Noise Control Act, the demand for detailed analysis soared, and decision makers began to look to acoustical scientists for answers regarding the planning of new roadways and the design of noise mitigation. Partial bans on motor vehic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Women's Engineering Society
The Women's Engineering Society is a United Kingdom professional learned society and networking body for women engineers, scientists and technologists. It was the first professional body set up for women working in all areas of engineering, predating the Society of Women Engineers by around 30 years. History The society was formed on 23rd June 1919, after the First World War, during which many women had taken up roles in engineering to replace men who were involved in the military effort. While it had been seen as necessary to bring women into engineering to fill the gap left by men joining the armed forces, the government, employers, and trades unions were against the continuing employment of women after the war. The Restoration of Pre-War Practices Act 1919 gave soldiers returning from World War I their pre-war jobs back and meant many women could no longer work in roles they were employed to fill during the war. This led a group of seven women, including Lady Katharine Parso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woman's Hour
''Woman's Hour'' is a radio magazine programme broadcast in the United Kingdom on the BBC Light Programme, BBC Radio 2, and later BBC Radio 4. It has been on the air since 1946. History Created by Norman Collins and originally presented by Alan Ivimey, ''Woman's Hour'' was first broadcast on 7 October 1946 on the BBC's Light Programme. Janet Quigley, who was also involved with the birth of the UK radio programme ''Today'', has been credited with "virtually creating" the programme. The programme was transferred to its current home in 1973. Over the years it has been presented by Mary Hill (19461963), Joan Griffiths (19471949), Olive Shapley (19491953), Jean Metcalfe (19501968), Violet Carson (19521956), Marjorie Anderson (19581972), Teresa McGonagle (19581976), Judith Chalmers (19661970), Sue MacGregor (19721987), Jenni Murray (1987–2020), Martha Kearney (1998 to March 2007), and Jane Garvey (8 October 2007 to December 2020).

National Academy Of Engineering
The National Academy of Engineering (NAE) is an American nonprofit, non-governmental organization. The National Academy of Engineering is part of the National Academies of Sciences, Engineering, and Medicine, along with the National Academy of Sciences (NAS), the National Academy of Medicine, and the National Research Council (now the program units of NASEM). The NAE operates engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. New members are annually elected by current members, based on their distinguished and continuing achievements in original research. The NAE is autonomous in its administration and in the selection of its members, sharing with the rest of the National Academies the role of advising the federal government. History The National Academy of Sciences was created by an Act of Incorporation dated March 3, 1863, which was signed by then President of the United States ...

Non-executive Director
A non-executive director (abbreviated to non-exec, NED or NXD), independent director or external director is a member of the board of directors of a corporation, such as a company, cooperative or non-government organization, but not a member of the executive management team. They are not employees of the corporation or affiliated with it in any other way and are differentiated from executive directors, who are members of the board who also serve, or previously served, as executive managers of the corporation (most often as corporate officers). However they do have the same legal duties, responsibilities and potential liabilities as their executive counterparts. Non-executive directors provide independent oversight and serve on committees concerned with sensitive issues such as the pay of the executive directors and other senior managers; they are usually paid a fee for their services but are not regarded as employees. All directors should be capable of seeing corporate and business ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Excellence Framework
The Research Excellence Framework (REF) is a research impact evaluation of British higher education institutions. It is the successor to the Research Assessment Exercise and it was first used in 2014 to assess the period 2008–2013. REF is undertaken by the four UK higher education funding bodies: Research England, the Scottish Funding Council (SFC), the Higher Education Funding Council for Wales (HEFCW), and the Department for the Economy, Northern Ireland (DfE). Its stated aims are to provide accountability for public investment in research, establish "reputational yardsticks", and thereby to achieve an efficient allocation of resources. Critics argue, inter alia, that there is too much focus on the impact of research outside of the university system, and that impact has no real relevance to the quality of research. It is suggested that REF actually encourages mediocrity in published research, and discourages research which might have value in the long term. It has repeatedly bee ...

Jerome Clarke Hunsaker
Jerome Clarke Hunsaker (August 26, 1886 – September 10, 1984) was an American naval officer and aeronautical engineer, born in Creston, Iowa, and educated at the U.S. Naval Academy and the Massachusetts Institute of Technology. His work with Gustav Eiffel outside Paris led to the first wind tunnel in the US at MIT. He was instrumental in developing a weather reporting and airway navigation. Hunsaker was also pivotal in establishing the theoretical and scientific study of aerodynamics in the United States. And he was primarily responsible for the design and construction of the Navy-Curtiss airplane (NC-4) that accomplished the first transatlantic flight (May 1919), and the first successful shipboard fighter. Later he championed lighter-than-air flight but the loss of the Navy airship he designed, the USS Akron, led to the withdrawal of federal support. His WW2 chairmanship of the National Advisory Committee for Aeronautics (NACA) was notable for favouring the development of existi ...

Concorde
The Aérospatiale/BAC Concorde () is a retired Franco-British supersonic airliner jointly developed and manufactured by Sud Aviation (later Aérospatiale) and the British Aircraft Corporation (BAC). Studies started in 1954, and France and the UK signed a treaty establishing the development project on 29 November 1962, as the programme cost was estimated at £70 million (£ in ). Construction of the six prototypes began in February 1965, and the first flight took off from Toulouse on 2 March 1969. The market was predicted for 350 aircraft, and the manufacturers received up to 100 option orders from many major airlines. On 9 October 1975, it received its French Certificate of Airworthiness, and from the UK CAA on 5 December. Concorde is a tailless aircraft design with a narrow fuselage permitting a 4-abreast seating for 92 to 128 passengers, an ogival delta wing and a droop nose for landing visibility. It is powered by four Rolls-Royce/Snecma Olympus 593 turbo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
