Aircraft Ship Integrated Secure and Traverse. The Aircraft Ship Integrated Secure and Traverse (ASIST) system is a shipboard helicopter landing system developed by Canadian company Indal Technologies (now part of US conglomerate Curtiss-Wright). ASIST completed sea trials by July 31, 1992, and production units are in operation with the Chilean Navy, Republic of Singapore Navy, Turkish Navy and United States Navy.

Mode of Operation
The ASIST system employs a sophisticated electro-optic tracking system which detects a laser beacon-equipped helicopter. The system tracks the helicopter and provide real time helicopter position simultaneously via visual cues to the pilot. A computer-controlled rapid securing device will also be driven by the position data to track the helicopter at low hover. Once the system has detected that the helicopter has landed on the deck, the securing device automatically approaches the helicopter and secures it. The securing device and traversing system are then used to align the helicopter with the deck tracks and manoeuvre it into a hangar, all without the need for manned intervention. All ASIST electrical and mechanical systems are modular and are housed in the hangar or below deck level to minimize space and weight requirements.

Kugelfischer. Kugelfischer injection (also called System Kugelfischer) is the name for a mechanical fuel injection (MFI) pump. It was produced by FAG Kugelfischer and later by Robert Bosch GmbH
Derived from diesel pumps from the early 1960s, the Kugelfischer system was a mechanical injection pump for performance vehicles.  It was among the first units with manufacturer-customizable fuel delivery maps which used rpm, throttle position, temperature, and sometimes barometric pressure as inputs.  This was accomplished mechanically, not electronically, using cones (irregularly shaped, two-dimensional cams) to encode the maps. 

In the late 1960s and early 1970s, it was fitted to a variety of production vehicles from BMW, Ford UK, Lancia, Peugeot - 404 and 504 between 1961 and 1983, and others.  It is perhaps best known for its use by BMW in the 2000tii/2002tii (and later, the 2002 Turbo) from 1970 to 1975, the 1964–1976 Porsche 911/911S/Carrera RS/RSR/Carrera MFI, and the BMW M1 supercar from 1978 to 1981.   Due to high manufacturing cost however, it became economically undesirable with the introduction of cheaper electronic engine management systems (and continuous-injection mechanical systems) by the end of the decade.  However, the Kugelfischer system continued to be used as a specialty injection pump for purpose-built race engines into the 1980s such as the 1982 Porsche 911 SC/RS.

Taiwan Strait Tunnel Project. The Taiwan Strait Tunnel Project is a proposed undersea tunnel to connect Pingtan in Mainland China to Hsinchu in Taiwan as part of the G3 Beijing–Taipei Expressway.  It has seen a few academic studies from the China side, but no interest from the Taiwan side, which views such proposals as propaganda.  In addition to political factors, the project is generally not considered realistic due to technical and cost concerns.

Proposals 

First proposed in 1996, the project has since been subject to a number of academic discussions, including by the China Railway Engineering Society. The route between Pingtan and Hsinchu has been proposed because of its short distance and its relative geological stability (in a region frequented by earthquakes). In 2005, an academic from the Chinese Academy of Engineering stated that the project was one of five major undersea tunnel projects under consideration for the next twenty to thirty years.

Reception in Taiwan 
The project is not considered viable due to the staggering costs, unsolved technical problems, and foremost a lack of interest from the Taiwanese. At nearly   m undersea, the proposed tunnel would be 6.4 times longer than the existing Seikan Tunnel (), nearly 4 times longer than the Channel Tunnel () (the current longest underwater tunnel segment), and two-thirds longer than the proposed Bohai Strait tunnel project . In addition, Taiwan is much concerned about the tunnel's potential use by China in military actions.  Nonetheless, in July 2013, the Chinese State Council approved plans for the project.

As the relation between Taiwan and China worsens, the proposal has been mocked in Taiwan, along with the Beijing–Taipei high-speed rail corridor.

LIPNUR Sikumbang. 

The LIPNUR Sikumbang () was a low-wing monoplane of mixed construction built in Indonesia in 1954 as a COIN and anti-guerrilla-warfare aircraft. Of conventional configuration, it had fixed tricycle undercarriage and seated the pilot under a bubble canopy. A single example was built under the designation NU-200 in 1954, and another as the NU-225 in 1957. The latter machine was grounded in 1967.

Design and development

NU-200
Due to various internal rebellions that happened across Indonesia in the early 1950s, Major Nurtanio Pringgoadisuryo, head of Indonesian Air Force’s Research, Development, and Production Depot, was inspired to design and build a light counter-insurgency aircraft to meet the demands of the Air Force. Nurtanio, together with two technicians, Second Lieutenant Achmad and Second Lieutenant Tosin, built the aircraft in their spare time with limited funds from the Air Force and tooling, spare parts and materials available at the depot's facility in Andir airfield, Bandung.

The aircraft was powered by a single 200 hp de Havilland Gipsy Six air-cooled inverted inline piston engine with two-bladed fixed-pitch propeller. The fuselage was made from welded 4130 steel (chromoly) with metal skins, while the wings and tail surfaces were all-wood material. It has cantilevered low wing with NACA 23012 airfoil, with the wing consisted of one-piece two-spar wooden construction with plywood covering, fitted with electric split-type flaps and statically balanced ailerons. The tail surfaces were made of wood with plywood skins, with trim-tab fitted to the port elevator and rudder. The aircraft has a fixed tricycle landing gear with cantilever oleo shock struts and non-steerable nose wheel.

The first prototype was dubbed NU-200 Sikumbang. The "NU" stands for Nurtanio, while "200" refers to the power of its Gipsy Six engine. The NU-200 first flew on 1 August 1954.

Yakovlev Yak-30 (1960). The Yakovlev Yak-30 (NATO reporting name Magnum), originally designated Yakovlev 104, was Yakovlev's entry in a competition for the first military jet trainer aircraft designed for Warsaw Pact nations. Designed to succeed the Yak-17UTI, it also led to the development of the Yakovlev Yak-32 sport jet. The Yak-30 lost to the L-29 Delfin, and neither it nor the Yak-32 entered production.

Factory testing took place from 20 May 1960 through March 1961. A total of 82 flights were made with 43 hours 36 minutes of flight time. No difficulties in operating the aircraft were found.
The competition ultimately came down to three aircraft, the rivals being the Czechoslovak L-29 Delfin, and the Polish TS-11 Iskra. The Iskra was quickly eliminated and sent back to Poland, leaving the Yak-30 in a head-to-head competition with the L-29, in which the Yak design showed far better performance, including lower weight, better maneuverability and lower production costs. However, in the end, a political decision was reached to select the more robust Czechoslovak L-29 in August 1961 to serve as the primary jet trainer for all Soviet and Warsaw Pact nations except for Poland. Immediately after this decision OKB pilot Smirnov set several official light jet world records in the Yak-30.
These included speed over a 25 kilometer course  (767.308 km/h), and maximum altitude of 16,128 meters.
One of the surviving prototypes is on display at the Central Air Force Museum, at Monino, outside of Moscow.

Transferability (chemistry). In chemistry, transferability is the assumption that a chemical property that is associated with an atom or a functional group in a molecule will have a similar (but not identical) value in a variety of different circumstances. Examples of transferable properties include:
Electronegativity
Nucleophilicity
Chemical shifts in NMR spectroscopy
Characteristic frequencies in Infrared spectroscopy
Bond length and bond angle
Bond energy

Transferable properties are distinguished from conserved properties, which are assumed to always have the same value whatever the chemical situation, e.g. standard atomic weight.

Gather (sewing). Gathering turns the edge of a piece of fabric into a bunch of small folds that are held together by a thread close to the edge. Gathering makes the fabric shorter where it is stitched. The whole of the fabric flares out into irregular, rolling folds beyond the gathered stitching. Gathering can be done by hand, with a machine, automatically, with elastic, or through channels.

Pleating and shirring are two different types of gather sewing.

In simple gathering, parallel rows of running stitches are sewn along one edge of the fabric to be gathered. The stitching threads are then pulled or "drawn up" so that the fabric forms small folds along the threads.

Gathering seams once involved tedious hand sewing of basting, which was time-consuming, especially with heavy fabric. However, finer gathers could be achieved. Now, a quick and easy way to make a gather is to use a wide zigzag stitch with a sewing machine. Both the upper and lower thread are pulled long and placed in front of the sewing machine. Then zigzagging is carefully sewn over the two threads without catching the threads in the process. Finally, the upper and lower threads are pulled to gather the fabric.

Types
Pleating or plaiting is a type of gathering in which the folds are usually larger, made by hand and pinned in place, rather than drawn up on threads; however, very small pleats are often identical to evenly spaced gathers. Pleating is mainly used to make skirts, but can have other uses. (See main article Pleat.)
Shirring or gauging is a decorative technique in which a panel of fabric is gathered with many rows of stitching across its entire length and then attached to a foundation or lining to hold the gathers in place. It is very commonly used to make larger pieces of clothing with some shape to them.

John David Gwynn. John David Gwynn (13 July 1907 – 21 November 1998) was a civil engineer with a special interest in renewable energy generation. In his youth he was one of Ireland's most distinguished cricketers.

John David Gwynn (known to family and friends as "David" or "JD") was born in Dublin on 13 July 1907. He was the eldest child of Edward Gwynn, an academic and sometime Provost of Trinity College Dublin, and Olive Mary Gwynn née Ponsonby. In accordance with family tradition he was educated at St Columba's College, Dublin and then at Trinity College Dublin, where he studied civil engineering. While still an undergraduate he was employed by the Siemens company to assist in their work on the Shannon hydroelectric scheme.

Gwynn went on to become a chartered civil engineer, a Fellow of the Institution of Civil Engineers and a Member of the Institute of Mechanical Engineers. After graduating BAI in 1930 he worked on Newport Bridge in Middlesbrough as an employee of the company Mott, Hay and Anderson. In 1936 he joined Balfour Beatty and was engaged on the extension of the Piccadilly Line for London Transport.

In the early 1940s J. D. Gwynn was again involved in developing hydro-electric power infrastructure, this time in Scotland. As the second World War continued he was put in charge of building the Churchill Barriers in Scapa Flow, Orkney, a task which occupied him from 1942 to 1944.

After the war he supervised further hydro-electric schemes both in the UK and overseas. Among other assignments he was chief engineer for the Kainji Dam Project in Nigeria. He became a director of Balfour Beatty in 1963, and a director of Engineering Power and Development Consultants in 1967. In 1966 an honorary MAI degree was conferred upon him by Trinity College, Dublin.

After his retirement from Balfour Beatty David Gwynn turned to the field of renewable energy, where with characteristic vigour and enthusiasm he proceeded to undertake research and develop innovative experimental designs. With his team he mounted trial schemes for various small scale stream-driven turbines as well as much larger tidal power devices, and he continued this voluntary work right up to the end of his life.

J D Gwynn married twice. His first wife, Grace Lee, was a historian; she died in 1964. They had two children: Lee Penelope, a teacher and local government politician, and Robin David, an academic historian and philatelist. J D Gwynn later married Esther Hulbert, a musicologist and singer, who also predeceased him. He died at the age of 91 on 21 November 1998.

Cricketing career

A right-handed batsman, he played one first-class match for Dublin University against Northamptonshire in July 1926, a match that also featured the Irish playwright Samuel Beckett.

Gwynn came from a cricketing family. Three of his uncles (Arthur, Lucius and Robin) all represented Ireland, whilst a fourth uncle, Jack, played first-class cricket in India.

De Havilland Doncaster. The de Havilland DH.29 Doncaster was a British long-range high-wing monoplane of the 1920s built by de Havilland.

History
The DH.29 Doncaster was ordered by the British Air Ministry as an experimental long-range monoplane. The aircraft was a high-wing cantilever monoplane with unswept wings of wooden structure with a fabric covering. It had a box section wooden fuselage with a single fin. The crew of two sat in an open cockpit ahead of the wing. Two aircraft were built between 1920 and 1921 at Stag Lane Aerodrome. Early testing of the first aircraft (Serial J6849) resulted in a redesign of the engine installation. The second aircraft (Registered G-EAYO) was built as a ten-seat commercial aircraft. The airlines were not interested and further development was abandoned, effort being put into the biplane de Havilland DH.34. A proposed military reconnaissance version, the DH.30, was never built. The two aircraft finished their life at RAF Martlesham Heath with tests and trials, particularly on the thick-section cantilever wings. The Doncaster was the first British aircraft to use such wings.
