Informatics Forum. The Informatics Forum is a major building on the Central Area campus of the University of Edinburgh. Completed in 2008, it houses the research institutes of the university's School of Informatics.

Design 
The Forum is designed by Bennetts Associates with Reiach and Hall, architects, and Buro Happold, engineers. The architects' brief was to provide a "forum for interaction" that will foster synergies among the 500 researchers in Informatics: Artificial Intelligence, Cognitive Science, Computer Science, and Systems Biology, who have been brought together, under one roof, by this development.

The building was the first in Scotland to achieve a BREEAM rating of "excellent", and was constructed by Balfour Beatty.

History 
One of the major recommendations of the 1997 international review that led to the formation of Informatics as an academic grouping at Edinburgh, was that the university should provide a building for the collocation of Informatics. An options appraisal recommended that the university should plan for the collocation of Informatics in a new construction within the university's George Square Campus, using the long-vacant Crichton Street site.

In 2002, the university embarked on a fund-raising campaign. This was followed closely by the Edinburgh Cowgate Fire of December 2002, which destroyed a number of buildings, including some of the school's accommodation at 80 South Bridge. The school took over four floors of the Appleton Tower as emergency accommodation. In the following years, plans for the school's accommodation were revised to include six floors of the Appleton Tower, and a new building on the Crichton Street Site.

In all, £42M was raised from public and philanthropic sources. Planning approval was confirmed on 12 September 2005, and work on site commenced in October 2005. The Informatics Forum was opened by then First Minister Alex Salmond in September 2008.

The Forum is the first phase of the Potterrow Project, the redevelopment of a site, bordered by Potterrow, Crichton Street, Charles Street and Marshall Street, that was cleared for redevelopment by the university in 1963, and has been used as a car park ever since. The Potterrow Project is itself part of a more extensive masterplan, that will see the Potterrow underpass removed and the campus extended to link Old College to George Square.

Awards
The Informatics Forum, as part of the wider Potterrow development, was joint winner of the RIAS Andrew Doolan Best Building in Scotland Award in 2008.

EasyLanguage. EasyLanguage is a proprietary programming language that was developed by TradeStation and built into its electronic trading platform. It is used to create custom indicators for financial charts and also to create algorithmic trading strategies for the markets. External DLL's can be referenced using EasyLanguage which greatly extends its functionality.

The language was originally intended to allow creation of custom trading strategies by traders without specialized computer training. Simple practical commands may consist of regular English words, which makes some of the basic elements of EasyLanguage more intuitive to learn than more complex programming languages.

Example:
 Plain English: "If the close is greater than the high of 1 day ago, then buy 100 shares at market."
 EasyLanguage: "if the Close > the High[1] then Buy 100 shares next bar at market;"

While rudimentary commands can be executed using plain language expressions, computer programming experience is generally required to take full advantage of the more sophisticated algorithmic features of Object Oriented EasyLanguage (OOEL), which has been influenced by Object Pascal, C#, and C++ and makes extensive use of classes and dynamic-link libraries.

GuideWorks. GuideWorks, LLC is the joint venture of Comcast and Gemstar-TV Guide International that was formed in April 2004 for the purpose of creating navigation software (also known as Interactive Program Guides) for digital cable television. Comcast owns a majority stake in the venture.

The software developed by GuideWorks is widely deployed in Comcast digital cable systems throughout the USA, and delivers both Video On Demand and Digital Video Recorder features to consumers. Gemstar TV Guide markets the GuideWorks software to other cable companies.

Prior to the formation of the joint venture, Gemstar-TV Guide International, Inc developed and marketed the navigation software to Comcast and other cable operators. During this period, the name i-Guide became associated with the products, which gained a reputation for strong promotion of advertising similar to the ads that appear on web pages today. This advertising aspect underwent significant deemphasis after the formation of the GuideWorks joint venture in 2004.

In 2010, Rovi, the corporate descendant of Gemstar-TV Guide, pulled out of the venture. GuideWorks is now wholly owned by Comcast.

Almirante-class destroyer. The Almirante class were two destroyers built for the Chilean Navy by Vickers in Barrow in Furness, UK, in 1960, named after Chilean admirals. Their weapons and Marconi sensors were in advance of the RN , but their internal layout resembled that of the . They served until the late 1990s. They were fitted with a unique Vickers-designed 4-inch dual purpose naval gun, which fired up to 50 rounds per minute. The gun was in advance of the standard RN 4.5-inch guns, more automated and reliable than the  3 and 6-inch mounts, but not water-cooled. It was rejected for RN use because of doubt about its sustained firing, the large stocks of surplus WW2 single 4.5 and twin 4-inch guns which the RN claimed wrongly were close to the new 4-inch N(R) in performance, and mainly because it was a private out-of-house, Vickers design. The ships were modernised in Britain in 1975, and decommissioned in the late 1990s.

Programme

Chile decided to upgrade its destroyer fleet in the early 1950s and turned to British yards to fulfil the order. Bids were received from Vickers and Thornycroft; the Vickers design was chosen. The order was announced in January 1954 and finalised in 1955. The sensors were a mixture of British- and Netherlands-made radars.

Chile had considered buying a second pair of destroyers in the mid-1960s but instead purchased two s, a derivative of the , instead.

Ships

Vickers offered two similar ships to the Colombian Navy but the Colombians bought two s from Sweden instead.

George Edward Holbrook. George Edward Holbrook (March 4, 1909 – February 26, 1987) was a noted American chemical engineer and a founding member of the National Academy of Engineering.

Biography
Holbrook was born in St. Louis, Missouri, and studied chemical engineering at the University of Michigan where he received his BS (1931), MS (1932), and Ph. D. (1933). He then joined Du Pont, by 1939 was head of new products research at Jackson Laboratory, and in 1943 its assistant director. In 1949 Holbrook was appointed general superintendent of product development at Chambers Works, then the world's largest chemical plant. He subsequently moved to Du Pont headquarters, first as manager of process development for the Organic Chemicals business, and later as assistant director of the Development Department.

After a brief leave for government service - as deputy director and then director of the Chemical, Rubber, and Forest Products Bureau of the National Production Authority - Holbrook resumed his prior Du Pont work but also chaired Du Pont's Corporate Committee for Educational Fellowships and Grants. In 1955 he was named assistant general manager of the Organic Chemicals Department, and in 1957 general manager of the Elastomer Chemicals Department. In 1958 he was further promoted to vice president, director, and member of the Executive Committee.

Holbrook served on boards and committees for a number of universities, including the Carnegie Institute of Technology, University of Delaware, University of Michigan, University of Pennsylvania, University of Rochester, and Newark College. He was a member of the American Chemical Society, American Physical Society, Society of Chemical Industry, New York Academy of Sciences, Franklin Institute, American Association for the Advancement of Science, the Chemical Society (London), and honorary member of the Institute of Chemical Engineers (London), and served as president of the American Institute of Chemical Engineers in 1958.

Bell 207 Sioux Scout. The Bell 207 Sioux Scout is a modified Bell 47 helicopter, developed by Bell Helicopter under contract from the United States Army, as a proof-of-concept demonstrator for the Bell D-255 helicopter gunship design, featuring a tandem cockpit, stub wings, and a chin-mounted gun turret.

Design and development

After several years of development, Bell displayed the mockup of its D-255 "Iroquois Warrior" to Army officials in June 1962, hoping to solicit funding for further development. The D-255 was planned to be a purpose-built attack helicopter based on the UH-1B airframe and dynamic components with a new, slender airframe and a two-seat, tandem cockpit, featuring a grenade launcher in a ball turret on the nose, a 20 mm belly-mounted gun pod, and stub wings for mounting rockets or SS.10 anti-tank missiles.

A proof-of-concept contract was awarded to Bell in December 1962 for the Model 207 Sioux Scout, which was, in essence, a new forward fuselage and Bell 47G-3 dynamic parts fitted to a Bell 47J center and rear fuselage. The Sioux Scout included all the key features of a modern helicopter gunship – a tandem cockpit, stub wings for weapons, and a chin-mounted gun turret. The tandem cockpit placed the gunner in the lower front seat with the pilot in the rear, with both crew positions featuring flight controls. The gunner's position featured a gunsight and turret controls located in the center, so the flying controls were moved to the side of the front cockpit. The gunner controlled a chin-mounted gun turret with twin 7.62 mm (.308 in) M60 machine guns. The stub wings held external fuel tanks.

First flown on 27 June 1963, the Bell 207 demonstrated improved manoeuvrability over the Bell 47/OH-13, derived from the stub wings. A variety of different wings, cowlings and tail surfaces were tested on the 207 before it was turned over to the Army pilots at Fort Benning, Georgia for further testing at the end of 1963.  After evaluating the Sioux Scout in early 1964, the Army was impressed, but also felt the Sioux Scout was undersized, underpowered, and generally not suited for practical use.

Later in 1964, the Army requested proposals for its Advanced Aerial Fire Support System (AAFSS). Bell proposed the D-262, a smaller version of the D-255, making better use of the T53 engine from the UH-1. However, the Bell D-262 was not selected as a finalist in the competition, which was won by the abortive Lockheed AH-56 Cheyenne.

USNS Worthy. The USNS Worthy (T-AGOS-14) was a modified Stalwart-class ocean surveillance ship operated by the United States Navy.

Design
The Stalwart-class ocean surveillance ships were succeeded by the longer Victorious-class ocean surveillance ships. Worthy had an overall length of  and a length of  at its waterline. It had a beam of  and a draft of . The surveillance ship had a displacement of  at light load and  at full load. It was powered by a diesel-electric system of four Caterpillar D-398 diesel-powered generators and two General Electric  electric motors. This produced a total of  that drove two shafts. It had a gross register tonnage of 1,584 and a deadweight tonnage of 786.

The Stalwart-class ocean surveillance ships had maximum speeds of . They were built to be fitted with the Surveillance Towed Array Sensor System (SURTASS) system. The ship had an endurance of thirty days. It had a range of  and a speed of . Its complement was between thirty-two and forty-seven. Its hull design was similar to that of the s.

History

Stalwart-class ships were originally designed to collect underwater acoustical data in support of Cold War anti-submarine warfare operations in the 1980s. USNS Worthy was struck from the Navy registry in 1993 and modified to be Kwajalein Mobile Range Safety System (KMRSS) Worthy, a missile range instrumentation ship at Kwajalein Atoll's Ronald Reagan Ballistic Missile Defense Test Site, operated by the United States Army.

Rubber technology. Rubber Technology is the subject dealing with the transformation of rubbers or elastomers into useful products, such as automobile tires, rubber mats and, exercise rubber stretching bands.  The materials includes latex, natural rubber, synthetic rubber and other polymeric materials, such as thermoplastic elastomers. Rubber processed through such methods are components of a wide range of items.

Rubber products can be categorized into two main categories. 

 Dry rubber products (dry form)
 Latex (wet rubber) products (liquid form)

Vulcanization
Most rubber products are vulcanized, a process which involves heating with a small quantity of sulphur (or equivalent cross-linking agent) so as to stabilise the polymer chains, over a wide range of temperature. This discovery was made by Charles Goodyear in the 1844, but is a process restricted to polymer chains having a double bond in the backbone. Such materials include natural rubber and polybutadiene. The range of materials available is much wider however, since all polymers become elastomeric above their glass transition temperature. However, the elastomeric state is unstable because chains can slip past one another resulting in creep or stress relaxation under static or dynamic load conditions. Chemical cross links add the stability to the network that is needed for most practical applications.

Processing of rubber

Methods for processing rubber include mastication and various operations like mixing, calendering, extrusion, all processes being essential to bring crude rubber into a state suitable for shaping the final product. The former breaks down the polymer chains, and lowers their molecular mass so that viscosity is low enough for further processing. After this has been achieved, various additions can be made to the material ready for cross-linking. Rubber may be masticated on a two-roll mill or in an industrial mixer, which come in different types.

Rubber is first compounded with additives like sulfur, carbon black and accelerators. It is converted into a dough-like mixture which is called "compound" then milled into sheets of desired thickness. Rubber may then be extruded or molded before being cured.

2-Methylhexane. 2-Methylhexane (C7H16, also known as isoheptane, ethylisobutylmethane) is an isomer of heptane. It is structurally a hexane molecule with a methyl group attached to its second carbon atom. It exists in most commercially available heptane merchandises as an impurity but is usually not considered as impurity in terms of reactions since it has very similar physical and chemical properties when compared to n-heptane (straight-chained heptane).

Being an alkane, 2-methylhexane is insoluble in water, but is soluble in many organic solvents, such as alcohols and ether. However, 2-methylhexane is more commonly considered as a solvent itself. Therefore, even though it is present in many commercially available heptane products, it is not considered as a destructive impurity, as heptane is usually used as a solvent. Nevertheless, by concise processes of distillation and refining, it is possible to separate 2-methylhexane from n-heptane.

Within a group of isomers, those with more branches tend to ignite more easily and combust more completely. Therefore, 2-methylhexane has a lower Autoignition temperature and flash point when compared to heptane. Theoretically 2-methylhexane also burns with a less sooty flame, emitting higher-frequency radiation; however, as heptane and 2-methylhexane differ by only one carbon atom, in terms of branching, both burn with a bright yellow flame when ignited.

Compared to n-heptane, 2-methylhexane also has lower melting and boiling points.  A lower density of liquid is found in 2-Methylhexane than heptane.

On the NFPA 704 scale, 2-methylhexane is listed as a reactivity level-0 chemical, along with various other alkanes. In fact, most alkanes are unreactive except in extreme conditions, such as combustion or strong sunlight. At the presence of oxygen and flame, 2-methylhexane, like heptane, combusts mostly completely into water and carbon dioxide. With UV-light and mixed with halogens in solvents, usually bromine in 1,1,1-trichloroethane, a substitution reaction occurs.

Magnetic induction tomography. Magnetic induction tomography (MIT) is an imaging technique used to image electromagnetic properties of an object by using the eddy current effect. It is also called electromagnetic induction tomography, electromagnetic tomography (EMT), eddy current tomography, and eddy current testing.

Applications
The method is used in nondestructive testing and geophysics, and has potential applications in medicine. It is also used to generate 3D images of passive electromagnetic properties, which has applications in brain imaging, cryosurgery monitoring in medical imaging, and metal flow visualization in metalworking processes. Recently, eddy current sensors has been used to scan additive manufacturing for metal process layer-by-layer, producing eddy current tomography images. The company AMiquam has been developing this technology since 2020.
