Velocity Tower. Velocity Tower is a mixed use development next to the Inner Ring Road in Sheffield City Centre, South Yorkshire, England, overlooking Ecclesall Road.  The build is a continuation of a previous design to be built by Cala, titled 'Eclipse'.

Cala Eclipse 
The original plans for the site were for a single tower named Eclipse, the result of a project by Cala Developments and initially designed by Broadway Malyan. These designs called for a charcoal-grey cladded 22-story tower with a 12-story brickwork skin wing that was to provide 263 new apartments.

After successfully selling most of the apartments before construction began - Cala decided that the economic conditions were unfavourable and abandoned the scheme in 2005, causing concern among early investors by putting the land up for sale without a public announcement.

Velocity Tower 

In 2007 it was eventually confirmed that Velocity Estates were to take over the project with some design changes from Sheffield-based architects AXIS Architecture. The altered design included a high-quality glass cladding façade to replace the previously proposed brickwork skin. A taller ground floor was also introduced, and a rooftop wind turbine array was added to improve the building's green credentials.

Construction started in 2007 under the agreed planning permission of the previous Eclipse building while a further application was submitted to alter the appearance of the tower and meet the City Council's design standards.

An application for the tower to go up to 36 storeys was submitted on 6 March 2008, but this was ultimately rejected by Sheffield Council stating that a 33-36 storey tower "would unacceptably break the city's skyline in important distant views".

A further revision to the plans was submitted limiting the building to a 30-storey tower and also lowering the west-facing wing of the building to 5 floors. To compensate for this reduction, however, the plans included the design of a second smaller tower at the far end of the wing, which would climb to 17 storeys. These plans were accepted by the council on 9 September 2008.

On 23 November 2008, the construction crane was removed from the Velocity Tower site and structural work was halted. The tower now stands at 22 storeys of the 30 storeys planned, with, as of August 2009, the second tower and wing an unfinished concrete frame of two storeys, and the grounds fenced off.

Grand opening 
In December 2008, Velocity Tower - although unfinished - opened its doors to potential tenants.

William H. Doherty. William H. Doherty (August 21, 1907 – February 15, 2000) was an American electrical engineer noted for his invention of the Doherty amplifier.

Doherty was born in Cambridge, Massachusetts, received his B.S. degree in electrical communication engineering in 1927 and M.S. degree in engineering in 1928, both from Harvard University. After a few months in the American Telephone and Telegraph Company Long Lines Department in Boston, he joined the National Bureau of Standards to study radio phenomena. In 1929 he began work at Bell Telephone Laboratories where he developed high power radio transmitters for transoceanic radio telephones and broadcasting.

In 1936 he invented a means to greatly improve the efficiency of RF power amplifiers, quickly termed the "Doherty amplifier" (U.S. Patent 2,210,028). It was first used in a 500-kilowatt transmitter made by Western Electric Company and proposed for WHAS, Louisville, Kentucky, but the Federal Communications Commission restricted broadcast stations to 50 kilowatts maximum power, and WHAS would go on to install a 50,000 watt Western Electric Doherty transmitter. By 1940 Western Electric had incorporated Doherty amplifiers in 35 commercial radio stations worldwide, nearly all of these at the 50,000 watt level, and employing a 5,000 watt driver of conventional design. Post-World War II Western Electric would offer 5,000 and 10,000 watt Doherty transmitters, and several were installed in the United States as backup transmitters for Class I (now Class A) stations, and a few as main transmitters for Class II/III (now Class B) stations.

Doherty received the 1937 IEEE Morris N. Liebmann Memorial Award for his improvement in the efficiency of radio-frequency power amplifiers.

Port of Spain International Waterfront Centre. The Port of Spain International Waterfront Centre is a construction project aimed at revitalising and transforming the waterfront of the capital-city Port of Spain located in Trinidad and Tobago. The project is a part of the overall Vision 2020, a government policy attempting to take Trinidad and Tobago to developed country status by 2020. That policy has since been shelved. The towers, which were supposed to usher in the beginning of a "Financial Centre" never materialized, and have slowly been occupied by government departments and offices.

The master plan involves constructing two 26-story office towers, a 22-story Hyatt Regency Hotel, and the English-speaking Caribbean region's largest conference centre. It was completed in 2009. It has since become the tallest building in Trinidad and Tobago at  tall.

The location of the complex is #1 Wrightson Road, Port of Spain.

Kinetic Dynamic Suspension System. The Kinetic Dynamic Suspension System (KDSS) technology was employed initially in the Lexus GX 470, and subsequently the 200 Series Toyota Land Cruiser. The system was invented and developed by Kinetic Pty Ltd, a small R&D company based in Dunsborough, Western Australia. It optimally adjusts front and rear stabilizers based on a set of interconnected hydraulic cylinders.  The interconnection is made up of hydraulic piping and a control cylinder which is located at the frame rail.  KDSS, which is fully mechanical, can disengage the stabilizer bars (the bars are jointed, allowing movement independent of one another). This system will not engage during normal driving conditions, when hydraulic pressure is equal. In off-road conditions, KDSS activates when it senses that a wheel has dropped.

The Kinetic Dynamic Suspension System was first available as an option on the model year 2004 Lexus GX 470, a sport utility vehicle that was only sold in North America, and based roughly on the 120 Series Land Cruiser Prado. The system was also introduced in similar form on the 2008 Toyota Land Cruiser. For the 2008 Lexus LX 570, an electro-mechanical suspension was employed, retaining the function of the KDSS design but adding electronic components.

For the 2025 model year, KDSS became a Lexus-exclusive feature. Toyota will instead use a Stabilizer with Disconnection Mechanism (SDM), only for the front sway bar, which debuted in the 2024 Land Cruiser. This is a conventional stabilizer bar with an electronic actuator directly mounted to the bar at the front axle, activated by a button inside the cab.

Vehicles 
Models that have adopted the Kinetic Dynamic Suspension System to date include:
 2010–2016 Toyota 4Runner Trail Edition 
 2017–2024 Toyota 4Runner TRD Off-Road
 2008–2023 Toyota Land Cruiser 
 2004–present Lexus GX
 2010–2023 Toyota Prado

California Institute for Water Resources. The California Institute for Water Resources (formerly the University of California Water Resources Center) was an interdisciplinary research institute dedicated to developing and coordinating a system-wide approach to water conservation. The center was funded by the California State Legislature in 1957, and was located on the original 1907 site of the UC Citrus Experiment Station on Mount Rubidoux in Riverside County, California. WRC was administered by the UC Division of Agriculture and Natural Resources (ANR). It collected historic and other documents related to water topics through the Water Resources Center Archives (WRCA) (located on the UC Riverside campus) and made the collection available to the public.

ANR announced the impending closure of WRC on October 2, 2009. WRC officially closed on December 31, 2009. The website, publications and data continue to be hosted by WRCA.

1,3-Butanediol. 1,3-Butanediol is an  organic compound with the formula CH3CH(OH)CH2CH2OH, not to be confused with 1,4 Butanediol. With two alcohol functional groups, the molecule is classified as a diol. The compound without the R (or D) designation is racemic, which is what has been used in most studies before 2023. The compound is a colorless, bittersweet, water-soluble liquid. It is one of four common structural isomers of butanediol. It is used in grape flavoring, and as a precursor to some antibiotics.

Production and uses
Hydrogenation of 3-hydroxybutanal gives 1,3-butanediol:
CH3CH(OH)CH2CHO  +  H2  →  CH3CH(OH)CH2CH2OH
Dehydration of 1,3-butanediol gives 1,3-butadiene:
CH3CH(OH)CH2CH2OH  →  CH2=CH-CH=CH2  +  2H2O

Pharmacology
1,3-Butanediol has sedative, hypotensive and hypoglycaemic action comparable to ethanol, with the (R), also known as (D), enantiomer being more active. Fatty acid esters of 1,3-butanediol such as the acetoacetate, lactate or hexanoate have been researched for inducing ketogenesis.

Occurrence
1,3-Butanediol has been detected in green bell peppers, orange bell peppers, pepper (Capsicum annuum), red bell peppers, and yellow bell peppers. 1,3 Butanediol, | quote = Also referred to as 1,3-Butylene glycol, maintains FDA GRAS status as a flavor molecule.

3820. 3820 (pronounced Thirty-eight twenty) is a 4-6-2 steam locomotive operated by the New South Wales Government Railways between 1947 and 1970. It has been preserved by the NSW Rail Museum, Thirlmere.

Construction
3820 was built in 1947 by the New South Wales Government Railways', Eveleigh Railway Workshops as the 20th of 30 38 class locomotives built to haul express trains. The first five were built by Clyde Engineering to a streamlined design, whilst the later 25 locomotives in the class were built by the NSWGR's Eveleigh and Cardiff Locomotive Workshops and were unstreamlined.

Construction was delayed mostly due to material shortages during World War II. It was at various times allocated to Eveleigh, Enfield, Lithgow and Broadmeadow Locomotive Depots.

During the rundown of steam operation in New South Wales, 3820 had the distinction of some lasts:
May 1964: hauled official last steam hauled Riverina Express in May 1964
May 1964: last official revenue steam duty on the Main South line beyond Goulburn
13 December 1968: was the last C38 class to be overhauled whilst in regular service, both being overhauled together at Cardiff Locomotive Workshops
29 December 1970: worked the official last steam hauled express passenger train in Australia, the Newcastle Flyer
29 December 1970: last 38 class in revenue service when withdrawn

Preservation
Upon withdrawal, 3820 was placed in the custody of the New South Wales Rail Transport Museum and based at Enfield Locomotive Depot operating excursion trains including a journey to Melbourne with 3801, and the Last Run which it triple headed with 3203 and 3526 to Tarana on 21 April 1973 before the Public Transport Commission banned main line steam operation.

3820 was steamed on 1 January 1975, to act as a standby for 3801, which was used to haul fundraising trains for Cyclone Tracy survivors. In June 1975, it hauled 4001 and 2419 to Thirlmere when the New South Wales Rail Transport Museum relocated. It was then withdrawn. In 1980 it was hauled to Central station for display at an event commemorating 125 years of rail operations in New South Wales.

3820 is painted black with red lining whereas 3801 and 3830 wear a green livery. 3820 is considered to be of historic significance as the only remaining 38 class locomotive that remains in the same condition it was in at time of withdrawal and as such retains a significant amount of evidence for research purposes.

Operational system. An operational system is a term used in data warehousing to refer to a system that is used to process the day-to-day transactions of an organization. These systems are designed in a manner that processing of day-to-day transactions is performed efficiently and the integrity of the transactional data is preserved.

Synonyms 
Sometimes operational systems are referred to as operational databases, transaction processing systems, or online transaction processing systems (OLTP). However, the use of the last two terms as synonyms may be confusing, because operational systems can be batch processing systems as well.

Any enterprise must necessarily maintain a lot of data about its operation.

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 at very high frequencies. During World War II, he served as a consultant to the Office of Secretary of War. He and Edwin H. Armstrong designed a sensitive receiver used to detect a radar signal reflected from the Moon (Project Diana).

After the war, he served as a consulting engineer, primarily on military electronics systems, assistant to the President of Bell Telephone Laboratories 1956-1961, affiliate of the Institute of Science and Technology at the University of Michigan 1961-1965, and research director of the Polytechnic Institute of Brooklyn 1965 until retirement in 1967.

Llewellyn was president of the Institute of Radio Engineers in 1946, and awarded the 1936 IEEE Morris N. Liebmann Memorial Award for his results on high-frequency electronics and constant-frequency oscillators.

Browder J. Thompson. Browder J. Thompson (August 14, 1903 – July 4/5, 1944) was a noted American electrical engineer.

Thompson was born in Roanoke, Louisiana, and in 1925 received his Bachelor of Science degree in electrical engineering from the University of Washington, Seattle. In 1926 he joined General Electric's research laboratory to design vacuum tubes. In 1931 he transferred to the RCA Radiotron Company, in Harrison, New Jersey, as part of the company's antitrust settlement, to lead its electrical research. In 1941 he was elected a Fellow of the American Physical Society. Thompson was co-director of RCA Laboratories, Princeton, New Jersey, from 1942 until December, 1943, when he accepted a special assignment for the Secretary of War. He was killed in action in World War II while observing an air-to-ground radar during a night flight over Italy.

Thompson was a Fellow of the Institute of Radio Engineers, and received the 1936 IEEE Morris N. Liebmann Memorial Award "for his contribution to the vacuum-tube art in the field of very-high frequencies." The Browder J. Thompson Prize Award was named in his honor.

Stuart William Seeley. Stuart William Seeley (June 23, 1901 – November 4, 1978) was a noted American electrical engineer, best known for inventing the Foster–Seeley discriminator and SHORAN.

Seeley was born in Chicago, Illinois, and received his B.Sc. degree in electrical engineering from Michigan State College in 1925. From 1915 to 1924 he was an amateur radio experimenter and commercial operator, then worked at General Electric 1925–1926, Sparks Withington 1926–1935, and the RCA License Laboratory, starting in 1935.

In 1936, Seeley invented the Foster–Seeley discriminator with D. E. Foster, publishing details in 1937. It helped reduce the cost of FM radio receivers to a level comparable to AM receivers.

In 1938, while attempting to remove "ghost" signals from an experimental television system, Seeley realized that he could measure distances by time differences in radio reception. In summer 1940, Seeley proposed building SHORAN, a bombing navigation system for the United States Army Air Forces. Contract was awarded 9 months later, and SHORAN given its first military flight tests in August 1942. First procurement was spring 1944, with initial combat operations in northern Italy on December 11, 1944.

Seeley received the 1948 IEEE Morris N. Liebmann Memorial Award "for his development of ingenious circuits related to frequency modulation", and the 1960 Magellanic Premium from the American Philosophical Society for Shoran.

In 2007 the Pittsburgh Antique Radio Society published a bibliography of Seeley's writings. The U.S. Patents of Stuart W. Seeley (with a bibliography of Seeley's writings), 2nd edition, 2007.
