Walraven 2. 

The Walraven 2 was a colonial Indonesian, twin-engine cabin monoplane, commissioned by the Chinese-Indonesian aviation pioneer Khouw Khe Hien, designed by , and built by personnel of the Netherlands East Indies Army Air Force during the 1930s.

Design and development
The Walraven 2 was a two-seat low-wing cabin monoplane powered by two Pobjoy Niagara radial engines. Utilising a Göttingen 681 airfoil, the aircraft was designed by Laurens Walraven, who was Chief Engineer of the Royal Netherlands East Indies Army Air Force, to the specification of Khouw Khe Hien, son of the millionaire .

Operational history
The aircraft first flew on 4 January 1935. It was registered as "PK-KKH". Finding the aircraft to be satisfactory, the younger Khouw intended to start an aircraft company in the Netherlands East Indies, to build aircraft designed by Walraven. To promote this venture, the Walraven 2 was flown from Indonesia to the Netherlands and back at the end of 1935. His sister, Khouw Keng Nio, also made a name for herself by becoming the first woman of Chinese or colonial Indonesian nationality to become a certified pilot in March 1936.

However, the factory plan did not materialize after Khouw Khe Hien was killed in an air crash in February 1938. The aircraft was placed in storage at Andir airfield in Bandung shortly thereafter, and was destroyed on 19 February 1942 in a Japanese air attack.

AEG Wagner Eule. The AEG Wagner Eule was a German reconnaissance aircraft built in 1914 by Allgemeine Electricitäts Gesellschaft.

Development

The Eule (English: Owl) was one of a series of aircraft developed by the German electrical company AEG. Designed by an engineer named Wagner (first name unknown), the single engine, two seat, mid-wing monoplane aircraft featured a fuselage of welded steel tubs with fabric covering and a wing of oak wood with fabric covering.  The fuselage measured 4.77 meters with a cross section of 110 cm x 98 cm.  The wings were tapered and featured a scalloped, bat-like trailing edge and a curving leading edge, with an overall look that was much like that of a bird or bat.

The first prototype was built with a Gnome rotary engine and was used for taxi tests.  It was engulfed in a fire during the test period when a fire broke out during a repair being made on the aircraft's fuel tank. The second prototype of the aircraft was equipped with either a rotary engine or an inline 4-cylinder engine from a Ford Model T.   A few short flights were carried out to test the aerodynamic characteristics of the prototype before the design was abandoned.

The unusual wing configuration was not featured in AEG's subsequent aircraft designs, however, the welded metal framed, fabric-covered fuselage was carried forward into AEG's B, C, and J class aircraft.

Subsequently, the Eule prototype was put on display in the AEG aircraft assembly hall. Later, after the end of World War I, AEG donated the prototype to the German Aviation Collection in Berlin. During World War II, the Eule prototype was moved to German-occupied Poland and stored at Czarnków, near Poznań.  In 1945, the Russians advanced into Poland and the aircraft, along with many other planes from the German Aviation Collection, were abandoned by retreating German forces.

The collection was then put into storage by the Polish government in the Technical Museum and thereafter, in 1963, was shipped to the Narodowe Museum Lotnictwa (Kraków Aviation Museum), where it was put in storage for future conservation.

GECI SK-105 Skylander. The Skylander SK-105 was a project for a new twin-turboprop light aircraft, developed by Sky Aircraft, a subsidiary of GECI Aviation. The Skylander SK-105 was projected to enter service in late 2014. However, in July 2012, no prototype was even built. The project was stopped by the dissolution of the company, announced on 16 April 2013.

Design and development
The first reference to this project is known to be 1988 and the aircraft was called SB 100C 1 2 3.
The project was announced on 17 October 2001 at the Seoul Air Show. Design supervision was by the late Desmond Norman, co-designer of the Britten-Norman Islander. The first metal cut was scheduled for January 2004; the first of two prototypes were expected to fly in May 2005, but this has been postponed indefinitely, pending adequate funding.

By December 2007, plans were in hand for the formal programme launch in April 2008, following the signature of letter of intent by Turkish freight carrier ACT Airlines Group for 15 aircraft to be delivered between 2011 and 2021. Simultaneously, there was an announced partnership agreement for distribution  of the Skylander in Bulgaria, Hungary, Macedonia, Turkey and several Middle East countries. Progress was slowed by a change of manufacturing plant from Portugal to France during 2008, and the target in-service date remained 2011. The programme was structured for joint funding (initially US$120 million) by three risk-sharing partners, Korean Aerospace Industries being first, on 17 October 2001, to pledge US$30 million to secure responsibility for wing production.

In October 2009, a new design of the aircraft was presented. After another change of manufacturing plant location (Chambley-Bussières Air Base in Lorraine), the target date of entry into service has been postponed year after year and was proposed for 2014.

On October 4, 2012, given the lack of funding, GECI Aviation Sky Aircraft went into receivership.

Neurogrid. Neurogrid is a piece of computer hardware that is designed specifically for simulation of biological brains. It uses analog computation to emulate ion channel activity, and digital communication to softwire structured connectivity patterns. Neurogrid simulates one million neurons and six billion synapses in real time. The neurons spike at a rate of ten times a second. In terms of the total number of simulated neurons, it rivals simulations done by the Blue Brain Project. However, by running the simulation of whole neurons, instead of simulation on molecular level, it needs only one millionth of Blue Brain's power. The entire board consumes less than two watts of electrical energy.

Neurogrid was designed and built by the Brains in Silicon group at Stanford University, led by Kwabena Boahen. The Neurogrid hardware was first up and running in late 2009. Since then, it has been used to start performing simulation experiments.

The Neurogrid board contains sixteen Neurocores, each of which has 256 x 256 silicon neurons in an 11.9 mm x 13.9 mm chip. An off-chip RAM and an on-chip RAM (in each Neurocore) softwire horizontal and vertical cortical connections, respectively. With 61 graded and 18 binary programmable parameters, common to all of its silicon neurons, a Neurocore can model a variety of spiking and interaction patterns.

Thomas Davidson (naval architect). Thomas Davidson (28 August 1828 – 18 February 1874) was a naval constructor for the United States Navy.

Biography
Davidson was born in Nottingham, England on 28 August 1828. He came to the United States at the age of four with his parents, and settled in Philadelphia. Early on, he developed a talent for mechanical invention and construction, following which he was apprenticed to the trade of ship building with Matthew Van Dusen, while also studying mathematics with his brother George Davidson. His capabilities soon attracted the attention of John Lenthall, then chief constructor of the U. S. Navy.

In 1850, at the age of 22, he built his first vessel "from the stumps" on the banks of the James River, and soon after entered into business in Philadelphia. In 1861, he was appointed quartermaster over the ship carpenters in the Philadelphia Navy Yard, and in 1863 was promoted to assistant naval constructor. He attained the full grade in 1866 with the relative rank of commander, the office which he held until his death. At one time during the Civil War he conducted repairs of 42 vessels, both large and small, at the Philadelphia Navy Yard, and also built several new ships. The Tuscarora, sister ship of the Kearsarge, was built under his direction in 58 working days, and the Miami in 27 days. His greatest feat was the building, in 70 days, of the Juniata (1,240 tons, 7 guns) from the frame of a Florida live-oak frigate that had been seasoned for 23 years.

Davidson displayed his engineering abilities in the floating of the Monongahela, which had been driven inland on Santa Cruz Island during the earthquake of 18 November 1867, and left stranded  high. With a body of skilled men selected from different navy yards, in a little over three months he succeeded in moving the ship sideways to the water's edge, and thence for  over a bed of coral to deep water.

Subsequently, he was ordered on duty at the bureau of construction in Washington, and was busy with plans for developing a navy of armored vessels, torpedo boats, and fast cruisers. The models and drawings for the first large torpedo boats built in New York were executed by him. Davidson was about to be sent to Europe for an exhaustive study of foreign navies and navy yards when his health failed, leading to his death at the age of 45, in Philadelphia.

RagWing RW2 Special I. The RagWing RW2 Special I is a family of biplane, single engine homebuilt aircraft designed by Roger Mann and sold as plans by RagWing Aircraft Designs for amateur construction.

Design and development
The RW2 was designed as a single seat lightweight Pitts Special S-1 replica for the US experimental homebuilt aircraft category. The RW26 was added later and is a replica of the Pitts S-2 two-seater.

As with many RagWing designs the RW2 and 26 feature airframes constructed entirely from wood and covered with aircraft fabric. The airframe uses a Pratt truss. The RW2 has an optional 4130 steel tube fuselage. The landing gear is of conventional configuration with bungee suspension. The wings are detachable for storage or ground transport.

The RW2's installed power range is  and the standard engines are the  Kawasaki 440A and the  2si 460, although the  Rotax 447 has also been used. The RW26's installed power range is  and the standard engines are the  Rotax 503 and the  Rotax 912S.

In the early 2000s kits were available for construction, but today the aircraft are available only as plans. The designer estimates it will take 400 hours to complete either aircraft and claims that the RW2 can be built for US$5000, including a new engine.

LB&SCR A1X class 55 Stepney. London, Brighton and South Coast Railway A1X Class number 55 Stepney, named after the district of Stepney, is a preserved steam locomotive based at the Bluebell Railway in East and West Sussex, England. Stepney is well known as the first standard gauge engine to be based at the Bluebell Railway, arriving by rail on 17 May 1960. The junior (8 years old and under) membership scheme of the Bluebell Railway Preservation Society is known as the Stepney Club.

Stepney re-entered service on the Bluebell in May 2010 after a fast track overhaul and was used on light duties until its main steam pipe failed in early 2014. Stepney currently wears Stroudley Improved Engine Green, but previously wore the lined black livery that was carried during the first (1960) season on the Bluebell. On 14 January 2012, Stepney made an "only-morning" appearance in BR Lined Black with the "cycling lion" crest and its BR number, 32655, for a special photographic charter. It carried the same BR Lined Black Livery again on 17 April 2012 for another photographic charter, this time though with the later "ferret and dartboard" crest. It returned to "Bluebell Black" in time for its visit to the National Railway Museum's "Railfest" in the first week of June 2012. Stepney is now on static display at the Bluebell railway, awaiting new cylinders and work on the frames and boiler.

In popular culture 

Stepney appears in the music video for Tracey Ullman's "Move Over Darling" (1983).

Stepney was featured in The Railway Series book Stepney The "Bluebell" Engine by Wilbert Awdry, as well as its television adaptation Thomas & Friends.

Models 

Father H. T. Brown built a 2-inch scale model of the A1X Stepney in 1954, which was exhibited at The Model Railway Exhibition, Westminster, London.
