RoadXML. RoadXML is an open file format for the road networks description used by driving simulators.

Overview 

RoadXML was initiated to contribute to road network format standardization in order to enhance the interoperability between simulators. It is the outcome of the compilation of several original formats (GRS, RNS/RS, RND) developed in 1994 by academic and industrial partners: INRETS, Oktal, PSA Peugeot Citroën, Renault, Thales.

RoadXML offers a multi layer description of the environment for fast data access for real time applications.  Here are the four main layers of information:
 Topological: element’s location and connections with the rest of the network.
 Logical: element’s signification in a road environment.
 Physical: element’s properties (road surface or obstacles).
 Visual: element’s geometry and 3D representation.

History 

Until its 2.0 version, RoadXML was called RND (for Road Network Description):
 The version 1.0 was released in 2007 and used by PSA Peugeot Citroen.
 The version 1.3 was released in 2008 and was an alternative file format for the SCANeR II driving simulator, co developed by Oktal and Renault.
 The version 2.0 was released in 2009 as an open file format and was renamed RoadXML.
 The version 2.1 was released in June 2010.
 The version 2.2 was released in September 2010
 The version 2.3 was released in December 2011
 The version 2.4 was released in July 2013
 The version 2.4.1 was released in July 2016
 The version 2.4.6 was released in April 2019
 The version 3.0.0 was released in March 2020

Since the version 2.1, an open source parser for RoadXML is also available on SourceForge.

SPCA 90. The SPCA 90 was a civil transport aircraft built in France in the early 1930s.

Design and development
The SPCA 90 was a high-wing monoplane of conventional layout with a thick-sectioned, cantilever wing. The cabin was fully enclosed, and was large enough that the aircraft could be used as an air ambulance to carry two stretchers plus attendants. The fixed undercarriage consisted of divided main units and a tailskid. Only a single example was built (registration F-AKFJ), which saw service in Morocco.

In 1935, SPCA built an airliner version of the same design, designated 91T. The cargo area was fitted out as a passenger cabin with seats for eight passengers, a baggage compartment, and a lavatory. This was to be SPCA's last aircraft.

Variants
90 — utility aircraft (1 built)
91T — airliner

Weir Greenhouse. Weir Greenhouse is a historic greenhouse located across the street from the main entrance of Green-Wood Cemetery in Sunset Park, Brooklyn, New York City. It was designed by George Curtis Gillespie and built in 1895 by James Weir, Jr., a Brooklyn florist who had been in business for 50 years when he built the greenhouse for the business he operated with his son and grandson. It is a rectangular, wood frame and galvanized iron building with projecting bays and domes in the Victorian commercial style. The main entrance is set at an angle to the street corner and is octagonal in form. The rooftop features an octagonal cupola with a ball finial. Attached to the greenhouse is a one-story brick office structure.

The Weirs continued to operate the business until 1971, when they sold to the McGovern family. The building was designated a New York City Landmark in 1982. On February 2, 2012, the Weir Greenhouse was purchased by the neighboring Green-Wood Cemetery, which planned to preserve the greenhouse and restore elements which have decayed in recent years. By early 2015, structural stabilization of the vacant, decayed building was complete, and the project was scheduled to move toward restoration of the building to its 1895 appearance. , the restoration is still underway, but Green-Wood planned to convert the greenhouse into the cemetery's visitor center.

The greenhouse was made a New York City designated landmark in 1982. It was listed on the National Register of Historic Places in 1984.

House I. House I is a sculpture by Roy Lichtenstein. It has an illusion, which makes it appear inside out, or normally, depending on which way the viewer sees it.

It is located at the National Gallery of Art Sculpture Garden.

It was constructed of painted aluminum, modeled in 1996 and constructed in 1999.

Among his last works, it was a part of the House series (Lichtenstein). House II was shown at the Venice Biennale in 1997, and House III was shown at the Metropolitan Museum of Art.

Illusion 
The house uses optical illusion to play with perspective. To appreciate the full effect, walk at a steady rate along the arc of the sidewalk that runs in front of and nearly perpendicular to the sculpture, with your head turned to one side, facing the sculpture. The house will appear to be spinning in space.

Berkshire Concept 70. The Berkshire Concept 70, sometimes called simply the C-70, is an American, single seat, high-wing, 15 metre class competition glider that was designed by Arthur Zimmermann and produced by the Berkshire Manufacturing Corporation of Lake Swannanoa, New Jersey between 1971 and 1974.

Design and development
The Concept 70 was intended to be a domestic US fiberglass sailplane that would compete with the best European 15 metre aircraft being produced in the late 1960s. The company started out as a fiberglass aircraft repair shop founded by Zimmermann and Wolfgang Schaer, but quickly progressed to aircraft design and construction.

The aircraft is made from molded fiberglass, with an internal fuselage steel frame skeleton that connects the monowheel landing gear and the wing fittings to the fuselage, while also providing a protective cockpit cage for improved impact survivability. The prototype has an Eppler airfoil and an all-flying horizontal stabilator. Production aircraft featured a Wortmann airfoil, a more conventional tail, and flaps that deploy to 90° for glidepath control, as the aircraft lacks the speedbrakes or spoilers common to most sailplane designs. The flaps permit very steep approaches, allowing the aircraft to land in small fields with obstacles. The aircraft also has retractable landing gear and was available with optional water ballast tanks with a  capacity.

Production of the Concept 70 ended with 21 produced, when Zimmermann died in 1974. The aircraft was never type certified and all aircraft were registered as experimental aircraft in the Racing/Exhibition category.

Operational history
In March 2011 there were still 14 Concept 70s registered in the US.

North American Trade Schools. North American Trade Schools (NATS) is a private career school vocational school in Baltimore, Maryland. The school's campus is located in the unincorporated community of Woodlawn, Baltimore County, Maryland, adjacent to Security Square Mall. Its current enrollment consists of 529 full-time students.

History
In 1970, the Diesel Institute of America (DIA) was founded by Sheldon Monsein, then president of Central GMC/Kenworth inc. in Landover, Maryland. His intent in starting the DIA was born from his company's need for additional qualified mechanics to service the diesel engine vehicles in the Central GMC/Kenworth fleet.

Not too long afterward, DIA offered its first class for diesel engine technicians in a  garage in Landover, making the DIA the first trade school in the state of Maryland to offer training in the repair and maintenance of diesel engines. 
In September 1983, the Diesel Institute of America moved its operation to Grantsville, Maryland and, three years later, began offering training in driving commercial trucks.

In 2002, the DIA was purchased by EFC Trade, a Canada based business that specializes in providing career training through specialty schools. It was in 2004 that the Diesel Institute of America relocated from Grantsville to its current location in Baltimore and its name changed to North American Trade Schools. Matt Daly is the school director and has been with the company since it moved to Baltimore

Sharklet (material). Sharklet, manufactured by Sharklet Technologies, is a bio-inspired plastic sheet product structured to impede microorganism growth, particularly bacterial growth. It is marketed for use in hospitals and other places with a relatively high potential for bacteria to spread and cause infections.

The inspiration for Sharklet's texture came through analysis of the texture of shark skin, which does not attract barnacles or other biofouling, unlike ship hulls and other smooth surfaces. The texture was later found to also repel microbial activity.

History 

Sharklet is a bio-inspired material that was invented by Anthony Brennan, a materials science and engineering professor at the University of Florida, while working to improve antifouling technology for ships and submarines at Pearl Harbor.

Brennan noticed that sharks do not get fouled. He discovered that shark skin denticles are structured in a characteristic diamond-repeating micro-pattern with millions of small ribs at the micrometer scale. His mathematical model for the texture of a substance that would deter microorganisms from settling corresponds to the width-to-height ratio of shark denticle riblets. When compared to smooth surfaces, the first test resulted in an 85% reduction in green algae settlement.

Stress gradient 

Adherence prevention and translocation restriction have been demonstrated and are believed to significantly reduce the risk of device-associated infections. Sharklet's topography creates mechanical stress on settling bacteria, a phenomenon known as mechanotransduction. The surface variations induce stress gradients within the plane, which disrupt normal cell functions, forcing the microorganism to adjust its contact area on each topographical feature to equalize the stresses. Sharklet is made, however, with the same material as other plastics.

Sharklet micro-patterns can be incorporated onto the surfaces of a variety of medical devices during the manufacturing process. Sharklet micro-patterns have been tested to control the bio-adhesion of marine microorganisms, pathogenic bacteria, and eukaryotic cells. They reduce S. aureus and S. epidermidis colonization in a simulated vascular environment by around 70% when compared to smooth controls. This micro-pattern similarly reduces platelet adhesion and fibrin sheath formation by approximately 80%. An in vitro study found that it reduced the colonization of S. aureus and P. aeruginosa bacterial pathogens in a central venous catheters-relevant thermoplastic polyurethane.

Jelly roll (battery). The jelly roll or Swiss roll design is the design used in the majority of cylindrical rechargeable batteries, including nickel–cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), and lithium-ion (Li-ion). The design has this name because the cross section of the battery looks like a Swiss roll.

In this design, an insulating sheet is laid down, then a thin layer of an anode material is laid down, a separator layer is applied, and a cathode material is layered on top. This sandwich is then rolled up and inserted into a hollow cylinder casing. The battery is sealed, metal contacts are attached, and an optional button top is applied if the battery is intended to replace an AAA/AA/C/D alkaline battery. A label with the brand name is then applied, or a blank protective label, often green (for Ni-MH) or blue (for Ni-Cd) for a generic or OEM battery.

Occasionally, the design is also used for primary (non-rechargeable) batteries, like lithium iron disulfide (Li-FeS2) patented by Energizer, although most common primary batteries use the conventional rod-paste-tube design, like the zinc-carbon and its successor the alkaline battery.

The Swiss roll design is likewise used for the plates of cylindrical capacitors.
