Mitra personal mover. The Mitra personal mover is an Indian battery-operated mobility device. The vehicle is capable of carrying a single person and aimed to be useful particularly in airport corridors, institutional campuses and in speciality buildings such as hospitals where low noise pollution is required. The vehicle is twin motor based and works on unique hybrid steering mechanism developed by inventors Rishabh Sinha and Subhav Sinha.

History
Subhav Sinha, one of inventors, was selected as the 'International Climate Champion' for year 2010, a program run by British Council. The creation has been covered by CII (Confederation of Indian Industries) in Journal of Small Business and Enterprise as "Mitra shows path of Innovation". The Economic Times has featured their exhibition at The Auto Expo with the article 'Personalised mover' draws eyes at Auto Expo' Entrepreneur India magazine has also featured the Mitra in its start-up section in the article 'Mobility Gets Personal'. Techpedia, a portal of technology projects by students, an initiative of SRISTI (Society for Research and Initiatives for Sustainable Technologies and Institutions) has featured this vehicle in a list of its top-ranking projects. The vehicle has been covered by leading daily locals like The Hindu, and Deccan Chronicle.

Mitra was used at the Commonwealth Games 2010 held at New Delhi. It was also featured in the CII- I3 National Fair Exhibition, organised jointly by CII, Agilent Technologies and DST (Department of Science and Technology).  Mitra was displayed at the 10th Auto Expo held at Pragati Maidan in New Delhi, India.

Design
Rishabh Sinha and Subhav are the Mitra's developers. The vehicle is self balanced and has both standing and sit provision for a single person. Its unique alignment of wheels gives the vehicle additional stability by controlling the centre of gravity, and prevents the person from falling while accelerating, braking or during sharp turns. Being battery operated, this vehicle is eco-friendly as it does not emit any effluents and consumes less energy compared to existing petrol and diesel vehicles.

Sivel SD27 Corriedale. 

The Sivel SD27 Corriedale is an Italian two-seat light touring or training monoplane designed and built by Sivel Aeronautica. The Corriedale is a low-wing monoplane with side-by-side seating for two, and is powered by a nose-mounted Rotax 912 piston engine. It has a fixed landing gear with a swivelling nosewheel. Five pre-series aircraft were produced in 1994 before production started in 1995 and the aircraft was certified under the JAR-VLA. An aerobatic variant flew in 1995 with a larger 119 kW (160 hp) engine.

Frelon (material). Frelon is a polytetrafluoroethylene (PTFE) based material with other proprietary fillers to increase bearing characteristics, such as low wear, low friction, and high strength. It is chemically inert and self lubricating. It qualifies as a class III plain bearing. The load capacity of a frelon-lined bearing is typically four to eight times that of a comparable ball bearing; for instance, a  Frelon-lined bearing can support the same load as a  ball bearing.

Characteristics
Frelon creates a self-lubricating bearing surface by transferring some of the soft PTFE to the shafting during the running in process. It is almost universally chemically inert; the only materials that attack it are molten sodium and fluorine at elevated temperatures.

It has a plain bearing pressure rating (P) of ; dry velocity rating (V) of 140 surface feet per minute (sfm) (0.71 m/s); and a PV rating of 10,000 psi sfm (0.35 MPa m/s).

Additional lubrication can reduce friction and wear by 50%.

Fairmont Railroad Bridge. The Fairmont Railroad Bridge is a truss bridge that carries the Norfolk Southern Railway across the Monongahela River just north of Fairmont, West Virginia. The bridge was built in 1853 as one of the early works of Albert Fink, the engineer who popularized the use of iron structures as opposed to those that are made of stone masonry or wood. It was reconstructed in 1912 and continues to serve as a major industrial route.

Makhonine Mak-10. The Makhonine Mak-10, was a variable-geometry research aircraft, built to investigate variable area / telescopic wings during 1931 in France.

Design and development
In the early 1930s several designers became interested in the possibility of changing the configuration of wings between take off and fast flight. Two routes were explored, the first primarily involving camber and hence lift coefficient reduction and the other a decrease of wing area by span reduction at high speed.  The Schmeidler variable wing and that of the Gloster built Antoni-Breda Ba.15  were examples of the first group and the Makhonine Mak-10 of the second.

Details of the Mak-10 are sparse but its novel feature was a telescopic wing which increased the span for take-off by  or 60% of its high speed configuration.  The outer panels retracted into the central ones, their inner ends supported on bearings rolling along one or more spars. The ends of the centre section were reinforced with cuffs. The wing apart, it was a conventional cantilever low wing monoplane, with twin open cockpits, the rear one  sometimes faired in, and faired, fixed landing gear.  It was powered by a , three bank, W-configuration, twelve cylinder Lorraine 12Eb engine.

The first flight of the Mak-10 was on 11 August 1931. During four years of development the Mak-10 was re-engined with a  Gnome-Rhône 14K Mistral Major fourteen cylinder, two row radial engine which gave it a top speed of  and the new designation Mak-101.

44 years later, the Akaflieg Stuttgart FS-29 experimental high performance sailplane also used telescopic wings to optimise both low speed thermalling and high speed penetration performance without the added induced drag of camber and area changing flaps.

Crawford CLM. Crawford CLM was an all-metal, single-engine, high-wing transport based on the German Junkers F.13-type wing, produced by Crawford All Metal Aircraft & Motor Company, Los Angeles, California, in 1931.   Powered by a Wright Whirlwind radial air-cooled engine of approximately 220 hp.  Unique in its closely spaced enclosed landing gear, with large landing lights installed in the forward part. Only one was produced and there were no production orders.  It was evaluated by the Mexican Air Force.   One photo from the Museum of Alaska Transportation & Industry would seem to indicate that the one prototype was sold to an Alaskan bush plane operator.

Reverse architecture. Reverse architecture is a process of deducing the underlying architecture and design of a system by observing its behaviour. It has its roots in the field of reverse engineering.

Practicing reverse architecture is used to decipher the logistics of building. There are a variety of techniques available, the most notable being architecture driven modelling.
