Everett Dunn. Everett Wesley Dunn, (born August 1, 1892, Summit, South Dakota, died October 3, 1980, Hartley, Iowa, age 88) was a civil engineer and labor negotiator. He was known for his work with the Iowa State Highway Commission, which demonstrated his knowledge not only of engineering but of financing as well.

Early life

Everett Dunn was the son of Moncena and Lois Woodward Dunn. Moncena Dunn (1867–1944) was a farmer, optometrist, and inventor of the patented Dunn Ballot (fraud-proof coupon ballot). Everett Dunn was born August 1, 1892, at Summit, South Dakota. After graduating from high school in Minneapolis, he attended South Dakota State College at Brookings, South Dakota and graduated with a degree in Civil Engineering in 1913.

Engineering career
Dunn was county engineer at Eldora, Iowa, for several years, then served as District Highway Engineer for the State of Iowa at Sioux City, Iowa, until 1941, when he entered private practice. Dunn was employed by, or was a consultant for, the U.S. Water Adjustment Board (1944–1946), the Industrial Stabilization Commission (1950–1952), a Portsmouth, Ohio, plutonium plant (1952–1953), and was a special consultant for the Atomic Energy Commission at the Nevada proving grounds (1964–1967). During this time Dunn gained wide recognition for his facility with labor negotiations, contractors, and government agencies.

Family
Dunn was the brother of educator Wendell E. Dunn, uncle of chemical engineer Wendell E. Dunn, Jr. and musician Thomas Dunn.

Magnetis. Magnetis is a WiiWare and PC video game developed by Yullaby, and was released in 2009. The game is notably Yullaby's first independent project, after previously being commissioned to develop video games by third parties.

Gameplay
Magnetis is set in a fantasy industrial environment where various magnets and metallic blocks will stack up.  The combination of the magnets, gathered according to their polarity, aligned or not with metallic blocks, allow the player to make a complete line of elements to disappear. It is also possible to get rid of several lines in a row, such as combos.

Magnetis was developed for the WiiWare and Steam platforms using the GameStart engine, now known as Harfang 3D.

Interview with developers
NintendoLife Interviews: Magnetis - Yullaby

Reception
Despite its poor sales, Magnetis was generally met with good reviews.

IGN UK gave the game a 7.5 (out of 10), praising its "slick presentation" and "deep mechanics", but said that the "lack of any online functionality was disappointing".

Nintendo Life also gave it a similar score of 7 stars (out of 10), saying that "the music is possibly amongst the best you'll hear on WiiWare", but said there was a lack of variety in the gameplay.

Wiiloveit.com assigned the game a 25/30 with a "Very Good" rating. They felt it was a "captivating" and "unique take on the falling block concept". Praise was also given to the game for "work[ing] so well in a group setting", its "amazing musical soundtrack" and for its "sense of quality".

Ayrton–Perry winding. An Ayrton–Perry winding (named for William Edward Ayrton and John Perry) is a type of bifilar winding pattern used in winding wire on forms to make RF resistors.  Its advantage is that the resulting coil of wire has low values of parasitic inductance and parasitic capacitance.  Ayrton–Perry windings of resistance wire are used to make wirewound RF resistors that are used at high frequencies, where inductance and capacitance are unwanted.

The winding is made of two separate wires wound in opposing directions along an insulating form and connected in parallel at the ends.  Since there are the same number of turns of wire in either direction, the magnetic fields of the two wires cancel each other out, so the coil has little inductance;  and since adjacent turns of the two wires are at approximately the same voltage, there is little parasitic capacitance between the turns.    

One disadvantage is that because the two lengths of resistive wire are connected in parallel, four times the length of wire (twice the length for each coil) is needed to make a given resistance, compared to when a single coil is used.

Roxxxy. Roxxxy, termed a "sex robot", is a full-size interactive sex doll. The robot is built by the New Jersey–based company TrueCompanion. Its engineer is Douglas Hines, founder and president of the company, who worked as an artificial intelligence engineer at the Bell Labs before he founded TrueCompanion. Development of Roxxxy is claimed to have cost between $500,000 and $1 million.

Roxxxy made its public debut at the AVN Adult Entertainment Expo (AEE) in Las Vegas on January 9, 2010. The gynoid stands 5 feet 7 inches tall and weighs 120 pounds (170 cm and 54 kg). It has synthetic skin and an artificial intelligence engine programmed to learn the owner's likes and dislikes. An articulated skeleton allows Roxxxy to be positioned like a human being but the doll cannot move its limbs independently. A pump installed in the robot powers an internal liquid cooling system. The Roxxxy prototype is claimed to have been modeled after a college-aged Caucasian fine arts student.

According to the website of the company, Roxxxy is not limited to sexual uses and "can carry on a discussion and expresses her love to you. She can talk to you, listen to you and feel your touch." Other features include touch sensors that give Roxxxy the ability to sense when it is being moved. The robot's vocabulary may be updated with the help of a laptop (connected to the back by cables) and the Internet.

Customers can ask TrueCompanion to customize the Roxxxy according to personal preferences, such as hair color, eye color, skin color, breast size and other features. Roxxxy is priced at $7,000 to $9,000 plus a separate subscription fee.

According to Douglas Hines, Roxxxy garnered about 4,000 pre-orders shortly after its AEE reveal in 2010. However, as reported by Jenny Kleeman in April 2017, no actual customers have ever surfaced with a Roxxxy doll, and the public has remained skeptical that any commercial Roxxxy dolls have ever been produced.

Deadweight tester. A dead weight tester apparatus uses weights to apply pressure to a fluid for checking the accuracy of readings from a pressure gauge.  A dead weight tester (DWT) is a calibration standard method that uses a piston cylinder on which a load is placed to make an equilibrium with an applied pressure underneath the piston. Deadweight testers are secondary standards which means that the pressure measured by a deadweight tester is defined through other quantities: length, mass and time.
Typically deadweight testers are used in to calibrate pressure measuring devices.

Formula

The formula on which the design of a DWT is based basically is expressed as follows :

where :

Piston cylinder design
In general there are three different kind of DWT's divided by the medium which is measured and the lubricant which is used for its measuring element :

 gas operated gas lubricated PCU's
 gas operated oil lubricated PCU's
 oil operated oil lubricated PCU's

Bratukhin B-11. The Bratukhin B-11 was a prototype Soviet twin-rotor transport helicopter and the last design of the Bratukhin aircraft design bureau to be built.

Development
The B-11 was similar to the design bureau's earlier B-5, a twin-rotor helicopter, with each rotor driven by an Ivchenko AI-26 radial engine. Each engine was housed in a pod on an outrigger with the related rotor above. Designed for a 1947 air force design competition for a general-purpose helicopter. Two prototypes were built and flown in June 1948, test flights showed a problem with rotor-blade stall at high speed and high resonant vibrations in the whole helicopter. In August 1948 the first prototype was grounded for investigation, but limited testing carried on with the second to find the causes of the problems.

On 13 December 1948 a blade on the right-hand rotor of the second prototype broke, and the subsequent crash killed the two crew. The prototype was then re-designed and re-built to overcome the problems, but when flying resumed in 1949 the stall occurred again. Bratukhin further modified the helicopter in May 1950 with new rotor blades, but development was soon abandoned, and soon after the design bureau was closed down.

Finite element limit analysis. A finite element limit analysis (FELA) uses optimisation techniques to directly compute the upper or lower bound plastic collapse load (or limit load) for a mechanical system rather than time stepping to a collapse load, as might be undertaken with conventional non-linear finite element techniques. The problem may be formulated in either a kinematic or equilibrium form.

The technique has been used most significantly in the field of soil mechanics for the determination of collapse loads for geotechnical problems (e.g. slope stability analysis). An alternative technique which may be used to undertake similar direct plastic collapse computations using optimization is Discontinuity layout optimization.

Kevlar KM2. Kevlar KM2 is a synthetic para-aramid fiber produced by DuPont. The fiber is an evolution of the original Kevlar fiber. The following quotes summarize Kevlar KM2's properties.

"DuPont created Kevlar KM2 to achieve the performance goals defined by casualty reduction testing for the United States Department of Defense. Today it is used extensively for fragmentation protection in the U.S. military. Helmets and vests made with Kevlar KM2 provide enhanced bullet and fragmentation resistance while remaining comfortable and breathable in the most inhospitable climates.

Excellent thermal stability at temperature extremes, water repellency, chemical stability and resistance to petroleum products have made Kevlar KM2 an indispensable asset to the military personnel who use it every day."

"Kevlar KM2 fiber is a transversely isotropic material. Its tensile stress–strain response in the axial direction is linear and elastic until failure. However, the overall deformation in the transverse directions is nonlinear and nonelastic, although it can be treated linearly and elastically in infinitesimal strain range. For a linear, elastic, and transversely isotropic material, five material constants are needed to describe its stress–strain response."

GE Dash 8-44CW. The GE C44-8W is a  diesel-electric locomotive built by GE Transportation Systems of Erie, Pennsylvania, part of the GE Dash 8 Series of freight locomotives. They are considered to be pre-production Dash 9s with D9-44CW internals and software housed in a Dash 8 carbody. They were numbered CSX 9000-9052. The first three were originally supposed to be the last order of Dash 8s for CSX thus having the smaller Dash 8 carbody. They have been derated to 4000 horsepower and are now designated C40-9W.

In keeping in GE tradition of giving nicknames to its locomotive series beginning with the "Dash 7" of the 1970s, the C44-8W was dubbed the "Dash 8" upon its debut. The design has since proven popular with North America railroads.

Harvey Slocum. Harvey Slocum (October 23, 1887 – November 11, 1961) was an American civil engineer and dam-building expert, known primarily for his part in the construction of Grand Coulee Dam in the United States and the Bhakra Dam in India. Slocum had little formal education, he started out as a labourer in a steel mill but eventually rose to the position of construction superintendent on the Grand Coulee Dam. Harvey Slocum was then Construction Superintendent of the Bull Shoals Dam built between 1947 and 1951.

Slocum joined the Bhakra Dam construction project as chief engineer in 1952 and imprinted on it his own distinctive style of working. He was a flamboyant personality who drove a current model powder blue Cadillac convertible; not expected of an engineer in those times in India. He was also known as a stern disciplinarian. All officers and workers on the dorm were mandated to dress uniformly and historian Ramachandra Guha writes that Slocum "could not abide the sloth and inefficiency that was rampant around him". Many workers from the United States Bull Shoals Dam project joined Slocum on the construction of the Bhakra Dam. A small city was constructed to house the U.S. workers. Slocum died in New Delhi at age 74.

Glass-Jet. Glass Jet is the name brand of a line of fiberglass runabout boats manufactured in the 1950s. These boats are some of the earliest examples of fiberglass boat construction. Inspired by aviation and the arrival of jet airplane technology, the boats have extra large tail fins like many of the automobiles of the same era. Glass Jet boats were manufactured by the J&R Plasticraft Corporation in Reeseville, Wisconsin.  This firm later ceased boat manufacturing and relocated to Waterloo, Wisconsin. Boat manufacturing continued in Reeseville, Wisconsin however by Quality Plastics, Inc. which produced the "Quality Glass" line of fiberglass boats. This firm went out of business in 1961. Though production numbers are unknown, many Glass Jet boats are known to exist and are presently sought after as collector's items.
