Sigma knowledge engineering environment. In the computer science fields of knowledge engineering and ontology, the Sigma knowledge engineering environment (SigmaKEE) is an open source computer program for the development of formal  ontologies. It is designed for use with the Suggested Upper Merged Ontology. It originally included only the Vampire theorem prover as its core deductive inference engine, but now allows use of many other provers that have participated in the CASC/CADE competitions.

Overview 

SigmaKEE is viewed as an integrated development environment for ontologies. The user's typical workflow consists of writing the theory content in a text editor and then debugging it using the SigmaKEE's tools.

It is written in Java and uses JSP for its web-based user interface. The interface allows the user to make queries and statements in SUO-KIF format and shows proof results with hyperlinks. For each step in the proof, SigmaKEE either points out that it is an assertion in the knowledge base or shows how the step follows from the previous steps using the rules of inference. The interface allows to browse the theory content with hyperlinks and presents hierarchies in a tree-like structure. It also allows to browse WordNet and Open Multilingual WordNet.

SigmaKEE supports THF, TPTP, SUO-KIF, OWL and Prolog formats and is able to translate theories between these formats. The theorem prover E, which supports TPTP standards for input and output, is integrated into SigmaKEE. It provides the e_ltb_runner control program which runs in an interactive mode. This program receives queries and applies relevance filters. It then runs multiple instances of E which search for an answer to the queries. If one of the instances finds the proof, all other instances are stopped and e_ltb_runner returns the answer to the SigmaKEE's backend.

Pál Király. Pál Király (1880–1965) was a Hungarian engineer and weapons designer.

Királyv was born in Budapest, Hungary in 1880. In 1902 he earned a degree in mechanical engineering, and later joined the Austro-Hungarian army, where he rose up to the rank of Artillery Captain by the end of World War I. Pál was employed by SIG Group from 1921-1924, where he and Gotthard End designed the SIG KE7. 

Király is best known for development of lever-delayed blowback firearms, and being employed by the Danuvia company in the 1930s and 1940s to design and produce weapons for the Royal Hungarian Army. He designed the Danuvia 39M and improved it into the Danuvia 43M submachine gun. After he moved to the Dominican republic, he designed the .30 Kiraly-Cristobal carbine, which was essentially a copy of his earlier work, specifically the 44M (an improved 43M). He made two more Cristobal carbine versions, the delayed blowback M2 in .30 Carbine and the gas-operated M3 in 7.62×51mm NATO. He patented the latter in 1961 as a competitor to the Belgian FN FAL.

Pál moved to the Dominican Republic in 1947, where he worked for the Armería San Cristóbal Weapon Factory and designed the Cristóbal Carbine.

WorldView-1. WorldView-1 (WV 1) is a commercial Earth observation satellite owned by DigitalGlobe. WorldView-1 was launched on 18 September 2007, followed later by the WorldView-2 in 2009. First imagery from WorldView-1 was available in October 2007, prior to the six-year anniversary of the launch of QuickBird, DigitalGlobe's previous satellite.

WorldView-1 was partially financed through an agreement with the National Geospatial-Intelligence Agency (NGA). Some of the imagery captured by WorldView-1 for the NGA is not available to the general public. However, WorldView-1 freed capacity on DigitalGlobe's QuickBird satellite to meet the growing commercial demand for multi-spectral geospatial imagery.

Design
Ball Aerospace built the WorldView-1 satellite bus and camera using an off-axis camera design identical to Quickbird, with the instrument's focal plane being supplied by ITT Exelis. The camera is a panchromatic imaging system featuring half-meter resolution imagery. With an average revisit time of 1.7 days, WorldView-1 is capable of collecting up to  per day of half-meter imagery.

Launch
 Launch Date: 18 September 2007
 Launch Time: 18:35 UTC (2:35 p.m. EDT)
 Launch Vehicle: Delta II 7920-10C, s/n D-326
 Launch Site: Space Launch Complex 2 West, Vandenberg Air Force Base, California

Edward Wilson (engineer). Edward Wilson (1820 in Edinburgh, Scotland – 1877) was a civil and locomotive engineer, notable for his work on the development of railways in the nineteenth century.

Career
After working initially for his father Wilson was articled to Stark & Fulton, Engineers, of Glasgow.

Wilson worked on the Caledonian Canal and various railways, including acting as the locomotive superintendent for the Hull and Selby Railway. From 1847 to 1853, he was engineer to the York and North Midland Railway, before assuming this position on the Midland Great Western Railway, Ireland in 1853. From 1858 he was Locomotive and Permanent Way Engineer for the Oxford, Worcester and Wolverhampton Railway (later the West Midland Railway).

In 1864 Wilson set up his own practice, Edward Wilson & Co, and worked on the Metropolitan Railway and on several new lines on the Great Western Railway and on many Great Eastern Railway projects, including the first phase of Liverpool Street Station in 1874. He was joined in the practice by his nephew, John Wilson (1846–1922), who was his apprentice, and by the architect W. N. Ashbee; collectively the three contributed to the Great Eastern works.

After Wilson's death in 1877 the practice of Edward Wilson & Co was carried on by John Wilson, in partnership with J. S. Macintyre, until it was dissolved in 1883 when John Wilson and Ashbee joined the permanent staff of the GER.

Myasishchev M-18. The Myasishchev M-18 was a design for a Soviet supersonic bomber with a variable-sweep wing. The aircraft was developed in response to a Soviet 1972 program for a new multi-misson, supersonic, variable geometry wing strategic bomber, with a maximum speed of Mach 2.3, as a response to the U.S. Rockwell B-1 Lancer program. The project was dropped in favour of the Tupolev Tu-160 program. Although the design was the most successful compared to the Tu-160 and Sukhoi T-4, it was dropped as Tupolev had the most potential to go ahead with the supersonic bomber project.

In 1973, Tupolev was assigned the development of a new aircraft based on the Myasishchev design.

Suzanna Darcy-Henneman. Suzanna Darcy-Henneman (some sources say her name is Susan Darcy)   is a Boeing test pilot and lead test pilot of Boeing 777 program. She was a pilot of a record-breaking 21,602.22 km flight from Hong Kong to London over the Pacific Ocean, America, and the Atlantic on November 9, 2005 in a Boeing 777-200LR. She joined Boeing in 1974, spent seven years as engineer, became trainer of airline pilots, and in 1985 was named Boeing Production Test pilot.

She graduated from the University of Washington in 1981 with a Bachelor of Science degree in Aeronautics and Aeronautical Engineering.

Career
She joined the Boeing company in 1974 as an assistant engineer, but was inspired to fly and began to take lessons in 1977. Around the same time, she attended the University of Washington to study aeronautics and astronautics, graduating with a Bachelor of Science degree in 1981. The following year, she was promoted at Boeing to an instructor in the training department. This job involved training pilots in how the aeroplanes functioned and writing parts of the operations manuals.

She was promoted to a test pilot position on October 31, 1985. This made her the first female test pilot employed by the company. In 1986, she was one of the speakers at the first World Aviation Education and Safety Congress, held in New Delhi. Over the next three years, Darcy accrued accreditation on the Boeing 737, 757 and 767. When she was accredited for the Boeing 747-400 in 1989, she was the first woman to Captain that type of plane. Her job also involved testing prototype planes, and on occasion, flying them to overseas buyers. By 1991, she remained one of two female test pilots for Boeing, alongside Rose Looper who joined shortly after her. She was part of the promotional Asian tour of the Boeing 777 in 1995, and was part of the team who flew a plane from Bangkok, Thailand, to Seattle in a world record time.

Suzanna appears in Season 1 Episode 1 “Flight” of Bill Nye the Science Guy in 1993 as a test pilot for Boeing.

Sodium phenoxide. Sodium phenoxide (sodium phenolate) is an organic compound with the formula NaOC6H5.  It is a white crystalline solid. Its anion, phenoxide, also known as phenolate, is the conjugate base of phenol. It is used as a precursor to many other organic compounds, such as aryl ethers.

Synthesis and structure
Most commonly, solutions of sodium phenoxide are produced by treating phenol with sodium hydroxide.  Anhydrous derivatives can be prepared by combining phenol and sodium. A related, updated procedure uses sodium methoxide instead of sodium hydroxide:
NaOCH3 +  HOC6H5   →   NaOC6H5  +  HOCH3
Sodium phenoxide can also be produced by the "alkaline fusion" of benzenesulfonic acid, whereby the sulfonate groups are displaced by hydroxide:
C6H5SO3Na  + 2 NaOH  →  C6H5OH  +  Na2SO3
This route once was the principal industrial route to phenol.

Structure
Like other sodium alkoxides, solid sodium phenoxide adopts a complex structure involving multiple Na-O bonds.  Solvent-free material is polymeric, each Na center being bound to three oxygen ligands as well as the phenyl ring. Adducts of sodium phenoxide are molecular, such as the cubane-type cluster [NaOPh]4(HMPA)4.

Reactions
Sodium phenoxide is a moderately strong base.  Acidification gives phenol:
PhOH  ⇌  PhO−  +  H+          (K = 10−10)
The acid-base behavior is complicated by homoassociation, reflecting the association of phenol and phenoxide.

Sodium phenoxide reacts with alkylating agents to afford alkyl phenyl ethers:
NaOC6H5  +  RBr →   ROC6H5  +  NaBr
The conversion is an extension of the Williamson ether synthesis.  With acylating agents, one obtains phenyl esters:
NaOC6H5  +  RC(O)Cl →   RCO2C6H5  +  NaCl

Sodium phenoxide is susceptible to certain types of electrophilic aromatic substitutions. For example, it reacts with carbon dioxide to form 2-hydroxybenzoate, the conjugate base of salicylic acid.  In general however, electrophiles irreversibly attack the oxygen center in phenoxide.

Jakob Ackeret. Jakob Ackeret, FRAeS (17 March 1898 – 27 March 1981) was a Swiss aeronautical engineer. He is widely viewed as one of the foremost aeronautics experts of the 20th century.

Birth and education 
Jakob Ackeret was born in 1898 in Switzerland. He received his diploma degree in mechanical engineering from ETH Zurich in 1920 under the supervision of Aurel Stodola. From 1921 to 1927 he worked with Ludwig Prandtl at the "Aerodynamische Versuchsanstalt" in Göttingen, witnessing a legendary period in the development of modern fluid dynamics. He received his PhD from ETH Zurich in 1927.

Academic career 
After completing his PhD, Ackeret worked at Escher Wyss AG in Zurich as chief engineer of hydraulics, where he applied, with great success, modern aerodynamics to the design of turbines.

He became a professor of Aerodynamics at ETH Zurich in 1931, where Wernher von Braun was one of his students.

Research 
Ackeret was an expert on gas turbines and was known for his research on propellers and on high-speed propulsion problems.

When he was at ETH Zurich, he actively participated in the solution of practical engineering problems, such as the design of variable-pitch propellers for ships and airplanes. His most important invention was the gas turbine with a closed circuit. He made the invention together with C. Keller.

Ackeret also contributed significantly to research in supersonic aerodynamics. He led the initial work on calculating the lift and drag on a supersonic airfoil and he proposed the designation of the "Mach number" for multiples of the speed of sound. On the 5th Volta Conference in Rome in 1935 Ackeret was planning to talk about supersonic lift, but because of "sensitive developments" for the Luftwaffe Adolf Busemann arranged their topics to be swapped (his paper about swept wings, which seemed an academic curioisuty back then, later became seminal) and presented a design for a supersonic wind tunnel.

Ackeret was awarded the Ludwig-Prandtl-Ring from the Deutsche Gesellschaft für Luft- und Raumfahrt (German Society for Aeronautics and Astronautics) for "outstanding contribution in the field of aerospace engineering" in 1965.

In 1976, he was elected foreign associate member of the American National Academy of Engineering for his "contributions to the understanding of high-speed and supersonic fluid mechanics, leading to significant improvements to the science of flight".

Tetrabutylammonium bromide. Tetrabutylammonium bromide (TBAB) is a quaternary ammonium salt with a bromide commonly used as a phase transfer catalyst. It is used to prepare many other tetrabutylammonium salts by salt metathesis reactions. The anhydrous form is a white solid.

In addition to being cheap, tetrabutylammonium bromide is also environmentally friendly, has a greater degree of selectivity, is operationally simple, non-corrosive, and can be recycled easily as well.

Preparation and reactions
Tetrabutylammonium bromide can be prepared by the alkylation of tributylamine with 1-bromobutane.

Tetrabutylammonium bromide is used to prepare other salts of the tetrabutylammonium cation by salt metathesis reactions.

It serves as a source of bromide ions for substitution reactions. It is a commonly used phase transfer catalyst. As its melting point is just over 100 °C and decreases in the presence of other reagents, it can be considered an ionic liquid.

Role in semi-clathrate formation 
TBAB is being extensively studied as a thermodynamic promoter in the formation of semi-clathrate hydrates which greatly brings down the pressure - temperature requirement for forming gas hydrates.
