Danit Peleg. Danit Peleg () is a fashion designer based in Tel Aviv, who created the first commercially available, 3D-printed clothing, and was recognized by Forbes as one of Europe's Top 50 Women in Tech.

Education and career 

Danit Peleg studied Fashion Design at the Shenkar College of Engineering and Design. Her dissertation researched the possibility of 3D-printing clothes. In 2014, she designed her first 3D-printed jacket, the Liberte, after a lot of experimentation with different materials and setups. After this initial success, she created more designs to create a complete collection.

After graduating in 2015, she started her own studio, via which she provides custom, 3D-printed designs for clients.

In 2016, she designed a 3D-printed dress for Amy Purdy, who wore this dress during a dance performance during the opening ceremony of the paralympics of 2016.

In 2017, a limited edition-set of 100 Bomber jackets were created. For $1500 a piece, clients could get their own customized jacket printed.

Danit Peleg organized a three-day workshop on 3D-printed fashion in 2018, where 15 students from all over the world could learn about her design process. That year she was also recognized as one of Europe's 50 most influential woman in tech by Forbes. She was named as one of the BBC 100 Women in 2019.

Flapper locking. Flapper locking is a type of locking mechanism used in self-loading firearms. It involves a pair of flappers on the sides of the bolt that each lock into an outwards recess in the receiver as the bolt is in battery. As the bolt is forced backwards after the firing of a cartridge, the flappers recede back into the bolt, therefore unlocking and sending the bolt backwards to cycle the gun. The design was patented in 1870 by Lieutenant Friberg of the Swedish Army, but the first actual example of a firearm that used this was made by another Swedish man named Kjellman in 1907. Most use of flapper locking came from the designs of the Soviet Union's Vasily Degtyaryov in the years surrounding World War II.

Alan Buchanan (naval architect). Alan Buchanan (1922–2015) was an English naval architect and sailor. He designed over 2400 vessels, including yachts that won Admiral's Cup, Cowes Week, and the Fastnet Race.

Buchanan started his career as a draftsman and aircraft engineer at the De Havilland Aircraft Company.   His family having a summer house in West Mersea, he was a regular visitor from a young age.   After he left de Havilland, he started as a boat designer firstly from his home in Enfield and then at his office which he established in Burnham-on-Crouch.

In the early years many of his designs were built by the boatyard of  William Wyatt in West Mersea. By 1950 he had a busy design office in Burnham employing about ten staff.

In 1948 the Burnham boatyard of RH Prior & Son started work on his first design specifically for ocean racing. This was the 10.3 metre (34 feet) Red Gurnet.

The first yacht he designed for himself and his wife was the 9.4m (31') LOA Bermudan Sloop Taeping. She was launched on 15 May 1954 having been built by Priors of Burnham.

In 1956 he was commissioned by the London Rowing Club for a vessel (Casamajor) which had to be fast but with minimal wash for use as a coaching boat for their racing eights on the River Thames. She was built by Tucker Brown & Co. of Burnham.

Sir Maurice Laing commissioned Buchanan to design him a yacht for ocean racing which was the 11.2m (37') Vashti. She was very successful in RORC racing and her sistership Rival, built in Australia, was handicap  winner in the 1961 Sydney Hobart race.

In the 1950s and 60s Buchanan was designing steel-built yachts where the basic steelwork was completed in Dutch yards, with the fitting-out being done in England.

Also in the mid-1950s the Buchanan Design Office was working on fibreglass designs and developed the first European-built glassfibre yacht, the 10.6m (35') Bonito. Their first production design was the 6.8m Crystal Class which later became the well-known Halcyon 23 of which well over 1000 have been built. The Diamond Class shortly followed, becoming in 1968 the Halcyon 27, and remained in production until 1975, about 200 having been built.

Although mainly known as a sailing yacht designer, Buchanan was also responsible for motor yachts like the 19.8 metre twin-screw Sita II, as well as numerous commercial motor vessels such as ferries and fishing vessels.

In 1997 he received a medal from the RINA for his small craft designs.

T. J. Jones Apartments. The T.J. Jones Apartments in Boise, Idaho, is a 2-story, brick and stone building originally designed in 1904 by Tourtellotte & Co. and expanded in 1911 by Tourtellotte and Hummel. The structure features a prominent Queen Anne corner turret, but Renaissance Revival characteristics also were discovered in preparation for adding the building to the National Register of Historic Places in 1982.

The original design included 12 2-story apartments, and after the building was expanded in 1911, it contained 17 2-story apartments. The foundation and load bearing walls were designed for a 4-story building to be completed at a future date, but the building has remained a 2-story structure.

Yamuna biodiversity park. Yamuna biodiversity park, located on Yamuna river front is a 9770 hectares biodiversity area in Delhi, India. It is developed by Delhi Development Authority (DDA) with the technical help of Centre for Environmental Management of Degraded Ecosystems (CEMDE), University of Delhi. It serves as an ideal alternative habitat for migratory and resident bird species. It also is designed to conserve the wild genetic resources of agricultural crops and enhance groundwater recharge and augment freshwater availability.

History

Delhi has 7554 hectares of fragmented forests which are deprived of wild animals due to unplanned urbanisation, and of the 400 wetlands, fewer than 3 or 4 were left. In 2015, Delhi already had Aravalli Biodiversity Park and Yamuna biodiversity park. Delhi Development Authority (DDA) engaged the scientist of Delhi University to develop four more biodiversity parks in Delhi, including the Northern ridge biodiversity park (Kamla Nehru Ridge), Tilpath Valley Biodiversity Park, Neela Hauz biodiversity park and phase-2 of the Yamuna Biodiversity Park. Phase-I of Yamuna biodiversity park focused on barren floodplains commenced in 2005 and phase-2 focused on the active floodplains commenced in 2015.

Restoration
In 2005 restoration of floodplains of Yamuna commenced, which had been lying barren due to sodic soil making it difficult for plants to grow. In Phase-I, 157 acres ecosystem was restored by developing two wetlands, a grassland and forest communities. Native plant species were reintroduced to reduce the salt content in the soil. The pH level (scale of acidity) of the soil was not neutral and detrimental to the success of the native Indian plants. Researchers from Delhi University had to plant one specific species of grass that brought the pH level from 10 to seven (neutral) level.

Flora
According to prof. C R Babu of Delhi University, initially only mongooses, lizards and 31 species of birds were there in the park up until 2004.
By 2014 the biodiversity park already had 900 species of native plants. The native species reintroduced included adina, sal, teak and hardwickia. As of 2019, it has about 1,500 species of plants and animals, and 200 species of birds.

Fauna
By 2014, the wetlands was already attracting thousands of migratory birds from Siberia, Central Asia and Europe. It had 200 species of birds, 75 species of butterflies, 10 species of snakes, and big mammals like porcupine, small Indian civet and wild boars.

William Henry Wheeler. William Henry Wheeler (1832–1915) was an English civil engineer, author, architect, inventor and antiquarian.

Wheeler was born in Hammersmith in 1832. He read for a degree at King's College London, and in 1867 became a member of the Institution of Civil Engineers, from which he was the recipient of the Telford Medal. He later became a member of the British Association, The Royal Agricultural Society and the International Congress on Navigation.

For forty-four years he was the Borough and Harbour Engineer of Boston, Lincolnshire, and there designed the town's New Dock, built between 1882 and 1884. He designed Boston Corporation's swimming baths, opened in 1880, Lincolnshire's first public park, and Boston Cottage Hospital, which opened in 1875 and later became Pilgrim Hospital. He carried out commercial and residential work, including designing a Jacobean-style staircase for a house on Boston High Street, and designed his own house on London Road which today is a preparatory school.

Wheeler was an authority in the field of low-lying land reclamation and Lincolnshire history, writing books on the topics including The History of the Fens of South Lincolnshire. He was an inventor of the eroder-dredger for which he received a bronze medal at the St Louis Exhibition, a freemason, and a member of Boston's Rifle Volunteer Corps, becoming its quartermaster sergeant.

He married Martha E. Sills of Casthorpe, near Barrowby, Lincolnshire, they producing two sons who both drowned at sea, and a daughter. He died in Bromley in 1915; his cremated remains were interred in St Nicholas' churchyard, Skirbeck, a church where he provided two stained glass windows in memory of his wife and sons.

Halberstadt CLS.I. The Germania C.I was a prototype two-seat general-purpose biplane built by Halberstadt during World War I.

Design and development
Halberstadt based the CLS.I on the earlier CL.IV design, with modifications including a modified wing profile of a lower curvature and a more streamlined rear fuselage. All these improvements were introduced to obtain a higher flight speed, (hence "S" in CLS standing for schnell, meaning "fast" in German). The prototype flew on 2 October 1918, but the aircraft didn't enter production due to the Armistice.

Halberstadt had plans for derivatives of the CLS.I armed with  revolver cannon, the CLS II and CLS X, but these designs never left the drawing board by the end of World War I.

IEC 61000-4-4. IEC 61000-4-4 is the International Electrotechnical Commission's immunity standard based on electrical fast transient (EFT) / burst transients. This publication is part of the greater IEC 61000 group of standards which is covered under IEC TR 61000-4-1:2016. The current third version of this standard (2012) replaces the second version (2004). The goal of this standard is to establish a common and reproducible reference for evaluating the immunity of electrical and electronic equipment when subjected to electrical fast transient/bursts on supply, signal, control and earth ports.

Note: This tables purpose is a quick overview. It does not contain the same level of detail as the official IEC 61000-4-4.

The cause of electrical fast transients (EFT) come from an arc when mechanical contact is open due to a switching process. Given the fast rise time and voltage of these pulses having a solid ground connection is important during the testing process. Testing for EFT often requires a capacitive coupling clamp (CCL), which is employed to add disturbances to nominal signals.

Moritz Schröter. Maximilian Moritz Schröter (25 February 1851 – 12 March 1925) was a German industrial engineer and university professor of thermodynamics and the theory of machines.

Life and career 
Moritz Schröter was the son of Moritz Schröter, who himself was a university professor. After his father′s death in 1867, Gustav Zeuner became the guardian of 16-year-old Schröter. After finishing the Gymnasium in Zürich, Schröter studied at the Polytechnikum Zürich, where he was awarded a diploma in engineering. From 1873 to 1876 he worked in the locomotive factory Georg Sigl in Wiener Neustadt. He then returned to Zürich, to become the university assistant of Georg Veith. In 1879, Schröter became a professor of theory of machines at the Technical University of Munich, where he built a new laboratory for machine design. From 1908 to 1911, he was the university's rector. Schröter helped designing four important machines in engineering history: the refrigerator (1887), the steam superheater (1894/1895), the Diesel engine (1897), and the steam turbine (1900).

Kondor D 1. The Kondor D 1, given the unofficial name Kondorlaus, was a German single seat, biplane fighter aircraft designed and built close to the end of WWI.

Design and development
The Kondor D 1 was an unequal span single-seat biplane of wooden construction, powered by a  Gnome Monosoupape rotary engine and armed with two  LMG 08/15 Spandau machine guns. The D 1 had a single spar lower wing with V interplane struts, similar to Nieuport 11 practice.
 
The first flight of the Kondor D 1 occurred in the autumn of 1917, but test flights showed it to be underpowered and Walter Rethel, with Paul Ehrhardt, developed an improved version of the design, the Kondor D 2, which Rethel completed after Ehrhardt retired due to ill health.

Confusion reigned after the second D-type competition at Aldershof because the Idflieg referred to the two Kondor D 2 prototypes as the D.I and D.II during the competition, which were actually fictitious designations.
