Midwestern Universities Research Association. The Midwestern Universities Research Association (MURA) was a collaboration between 15 universities with the goal of designing and building a particle accelerator for the Midwestern United States. It existed between 1953–1967, but could not achieve its goal in this time and lost funding. It was thought that President John F. Kennedy would have supported the MURA machine, while one of President Lyndon B. Johnson's first actions was the shutdown of the MURA machine and laboratory.

In its formative years, Donald Kerst was the director of MURA. At this institution, Keith Symon invented the FFAG accelerator, independently to Tihiro Ohkawa, which combines several concepts of cyclotrons and synchrotrons. FFAG concepts were extensively developed in MURA. The proposed MURA accelerators were scaling FFAG synchrotrons, meaning that orbits of any momentum are photographic enlargements of those of any other momentum.

The concept of FFAG acceleration was revived in the early 1980s, and gained interest up to the present day, see e.g. EMMA (accelerator).

Emerald Coast XL2 Sport. The Emerald Coast XL2 Sport is an American powered parachute that was designed and produced by Emerald Coast Aircraft.

The aircraft is no longer in production.

Design and development
The aircraft was designed as a US FAR 103 Ultralight Vehicles two-seat trainer. It features a parachute-style high-wing, two seats in tandem, tricycle landing gear and a single  Rotax 503 engine in pusher configuration.

The aircraft is built from a combination of bolted and welded 4130 steel tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes via a 2:1 ratio block system, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates sprung steel landing gear with large tundra tires.

When it was in production the XL2 was supplied in a number of forms. It could be purchased as a fully assembled and test flown aircraft, for US$ 9000 in 2003. It was also available as a just the basic carriage for US$3000 in 2003, with the buyer supplying his or her own canopy, instruments, engine and propeller. The company also built custom versions to order.

Roller electrospinning. Roller Electrospinning system a method for producing nanofibres was developed by Jirsak et al.. This method is known under the name Nanospider from Elmarco Company in Liberec. Roller electrospinning is the unique method which has been used in industry to produce nanofibers continuously.
Nanospider consists of rotating roller to spin fibers directly from the polymer solution. This roller spinning electrode partially immersed in the tank with the polymer solution. A grounded collector electrode is placed at the top of the spinner . A nonwoven backing material moves along the collector electrode which makes the production of the nanofibre layer a continuous process. Many Taylor cones are simultaneously formed on the surface of the rotating spinning electrode, which makes the technology highly productive.

Parameters
There are independent and dependent parameters for roller electrospinning.

Independent Parameters
Solution parameters: concentration of polymer solution, molecular weight of polymer, viscosity of polymer solution, surface tension and conductivity of polymer solution.
Process parameters: Applied voltage, velocity of rotating cylinder, collector type, distance from electrodes, velocity of take-up fabric, ambient parameters.

Dependent Parameters
Density of cones,
Life time of jet,

Edouard Dubied & Co. Edouard Dubied & Cie S.A. (French: Edouard Dubied & Co) was a Swiss enterprise producing machines for the textile industry.  It was formed in 1867 and closed in 1987.  It was based in Neuchâtel and then in Couvet.

History
Henri-Edouard Dubied was born in Couvet as the son of an absinthe distiller.  He founded the business after attending the Exposition Universelle (1867), where he bought the rights to make hand-cranked knitting machines from Isaac W. Lamb.  These knitting machines were originally designed for making socks and hosiery, and used a recently invented kind of mechanical needle.

His son, Paul-Edouard Dubied, who had trained as an engineer at the École polytechnique fédérale de Zurich (French: Zurich federal polytechnic college), succeeded him in 1878.  He added motors to the knitting machines and created a department of general mechanics specialising in lathes.  He focused on this new field, and in time expanded to Pontarlier in France, and handed over the knitting machine business to his son Pierre-Edouard.

Pierre-Edouard Dubied developed not only the two departments of the business, but also its social side: infirmary, dining hall, family support, health insurance, property and so on.  He created the Neuchâtel factory and a new department of machine tools.  In 1935 he bought Chemnitzer Strickmaschinen-fabrik AG (German: Chemnitz knitting machine factory), a German corporation that produced circular knitting machines.  These gave rise to the Wevenit family of knitting machines that later became famous.

Pierre Dubied had two sons and a daughter, and outlived all of them.  His daughter Pierrette married Rodo de Salis, by whom she had a son, Sker de Salis.  Sker joined the board of directors and was named Managing Director in 1973.  By this date, both kinds of knitting machine (circular and rectilinear) were electrically operated.

In 1967 the business celebrated its centenary.  Twenty years later, it went into administration.  The corporation was wound up in 1988.

Race engineer. A race engineer is a motorsport team member who analyses data to achieve the best performance from the vehicle and driver. The race engineer communicates with the team's data analyst, mechanics, and driver, both between and during races. Off the race track, the race engineer analyses historical data to determine the initial set-up for the next race event or test. The race engineer's duties also include hands-on management of the vehicle mechanics, organization of the testing schedule, and assurance of compliance with regulations. The race engineer seeks to make these activities occur as seamlessly as possible for the driver. Race engineers almost always have an academic degree in engineering or a related field.

A good race engineer must have good people skills. To be effective, the race engineer must have a good working relationship with not only the driver but also the rest of the team, both at and away from the track. Many times the race engineer is also "the face" of the team for the media; this is especially true during the race while the driver is inaccessible. This makes the race engineer's media skills a priority.

History
The role of the race engineer on racing teams has grown in importance since the adoption of on-board sensors that collect performance data. The race engineer's job is to evaluate the vehicle's performance gathered from both telemetry and the driver's feedback. The race engineer then seeks to improve performance with regard to the driver's desires by adjusting suspension, engine calibrations, aerodynamics, and other variables which affect the vehicle's performance on the race track.

Travel
Race engineers tend to travel extensively, especially during the racing season of their motorsport teams. At the highest level of professional motorsports, international travel is common. Offseason travel for race engineers is usually for testing, training, and visiting vendors.

Frequency domain decomposition. The frequency domain decomposition (FDD) is an output-only system identification technique popular in civil engineering, in particular in structural health monitoring.  As an output-only algorithm, it is useful when the input data is unknown.  FDD is a modal analysis technique which generates a system realization using the frequency response given (multi-)output data.

Algorithm 
 Estimate the power spectral density matrix  at discrete frequencies .
 Do a singular value decomposition of the power spectral density, i.e.  where  is a unitary matrix holding the singular vectors ,  is the diagonal matrix holding the singular values .
 For an  degree of freedom system, then pick the  dominating peaks in the power spectral density using whichever technique you wish (or manually).  These peaks correspond to the mode shapes.
 Using the mode shapes, an input-output system realization can be written.

Acme motorcycle (1939–1949). The Acme motorcycle was assembled and marketed by Bennett & Wood of Wentworth Avenue, Sydney, who also built Speedwell bicycles and were also BSA importers for New South Wales. The engine was a Villiers 122cc Mark 9D, and the frame was built locally. The bike was aimed at city commuters as a cheap and economical mode of transport. Production began in May 1939, and was phased out in 1949, due to the success of the imported BSA Bantam. The Acme, along with the Waratah, were the only two Australian-made motorcycles whose production span was before and after World War II.

Ardaite. Ardaite is a very rare sulfosalt mineral with chemical formula Pb19Sb13S35Cl7 in the monoclinic crystal system, named after the Arda River, which passes through the type locality. It was discovered in 1978 and approved by the International Mineralogical Association in 1980. It was the second  well-defined natural chlorosulfosalt, after dadsonite.

Greenish gray or bluish green in color, its luster is metallic. Ardaite occurs as 50 μm fine-grained aggregates of acicular crystals associated with galena, pyrostilpnite, anglesite, nadorite, and chlorine-bearing robinsonite and semseyite, in the Madjarovo polymetallic ore deposit in Bulgaria. Ardaite has a hardness of 2.5 to 3 on Mohs scale and a density of approximately 6.44.

The type locality is the Madjarovo polymetallic ore deposit in the Rhodope Mountains. Later its occurrence was proved in the Gruvåsen deposit, near Filipstad, Bergslagen, Sweden.

Union Aircraft Company. Union Aircraft Company  was an American aircraft manufacturer specializing in race aircraft.

California based aircraft designer Keith Rider had developed aircraft since 1916, and specialty aircraft for the National Air Races in the early 1930s. Starting his career as a draftsman for the Glen L. Martin Company. His five early racing designs built in a casket factory were state of the art monoplanes of the era. Despite large payoffs in the height of the depression, Rider fell into debt with the Story-Gawley Propeller company. He founded the Union Aircraft Company as a subsidiary of Story-Gawley to produce an aircraft that would provide enough winnings to pay off the debts, and seek future profits. The company produced the Rider R-6 "Eight-Ball".

The profits did not come about, leading to the end of aircraft production. In 1941 the parent company Story-Gawley was absorbed by Industrial Forming. Rider went on to become Vice President of Doak Aircraft, and project engineer for the Timm Aircraft Company.
