Walter Edwin Arnoldi. Walter Edwin Arnoldi (December 14, 1917 – October 5, 1995) was an American engineer mainly known for the Arnoldi iteration, an eigenvalue algorithm used in numerical linear algebra. His main research interests included modelling vibrations, acoustics, aerodynamics of aircraft propeller, and oxygen reclamation problems of space science. His 1951 paper The principle of minimized iterations in the solution of the eigenvalue problem is one of the most cited papers in numerical linear algebra.

Life and career
Born in New York City, Arnoldi earned a degree in mechanical engineering from the Stevens Institute of Technology in 1937 before achieving a Master of Science degree from Harvard University. He worked at the Hamilton Standard Division of the United Technologies Corporation from 1939 until his retirement in 1977; known as United Aircraft for much of his career. He was married to Flora (von Weiler) Arnoldi with whom he had two sons, Douglas and Carl. He lived in West Hartford, Connecticut since 1950. He died in West Hartford on October 5, 1995.

Krotite. Krotite is a natural mineral composed of calcium, aluminium and oxygen, with the molecular formula CaAl2O4. It is the low-pressure dimorph of CaAl2O4, of which the high-pressure dimorph is named dmitryivanovite.

Krotite was reported in 2011 in a calcium-aluminium-rich inclusion (CAI) in the carbonaceous chondrite meteorite NWA (North West Africa) 1934, which landed in Morocco. The mineral name was approved by the International Mineralogical Association (IMA 2010-038) and honors Alexander N. Krot, a researcher in cosmochemistry at the University of Hawaii at Manoa in Honolulu, Hawaii.

Researchers have found that the mineral, which has the same atomic arrangement as a man-made component of some types of concrete (specifically, calcium aluminate cements), forms under low pressure at a temperature of at least . These conditions of high temperature and low pressure are consistent with a hypothesis that the krotite grains found in the meteorite formed as high-temperature condensates from the solar nebula from which the Solar System formed, approximately 4.6 billion years ago. Thus, they are likely to be among the earliest minerals formed in the solar system.

The CAI containing the krotite was said to resemble a "cracked egg" because its rim was crosscut by cracks filled with iron and aluminum hydroxides. Researchers suggest that the mineral assemblage in the CAI was at one time surrounded by a hot gas that reacted with krotite crystals on the surface of the CAI. It is likely that cracks on this rim of the CAI were filled with hydrated oxides as a result of weathering that occurred after the meteorite landed on Earth.

Associated minerals include perovskite, gehlenite, hercynite, mayenite, grossite, hibonite, spinel and diopside.

Palmer BB Machine Gun. The Palmer BB Machine Gun is a training weapon capable of firing ball bearings.

During World War II, the USAAF and US Navy used thousands of Palmer BB machine guns to hone the skills  of aerial gunnery. This much larger gun is cycled by an electric solenoid and powered by compressed air. The air pressure is higher, at 180-200 psi, but the velocity runs between 500 and 600 f.p.s.

CloudTran. In computing, CloudTran, a transaction management product, enables applications running in distributed computing and cloud computing architectures to embed logical business transactions that adhere to the properties of ACID transactions.  Specifically, CloudTran coordinates ACID transactionality for data stored within in-memory data grids (e.g., Oracle Coherence, GigaSpaces, and Gemfire), as well as from the data grid to persistent storage systems (e.g., Oracle, MySQL, Microsoft SQL Server, MongoDB).

Distributed computing has traditionally relied on a technology called distributed transactions which is an algorithm used to coordinate the storing of a logically related set of data within more than one database or computer. CloudTran is aimed at addressing issues with this approach to improve on performance, scalability, and ease of implementation for application developers. In doing so, CloudTran enables a broad range of developers to implement highly scalable applications that run in cloud computing environments and distributed architectures. In addition, CloudTran is a manifestation of “Cloud Transaction Processing, or, “CloudTP”.

Iveco PowerStar. The Iveco PowerStar is an Australian developed and built tractor unit, assembled in Dandenong, Victoria. It is based on the European cab-over engine models, but with a bonnet, it was available as both a day cab, as well as a sleeper cab. When first released in 1998, it was available with Iveco engines, and also American engines, including the Detroit Diesel Series 60, Cummins ISM, ISX and Signature and Caterpillar C12 and C15. A selection of transmissions was also available, such as Iveco's ZF "Eurotronic", Eaton's RoadRanger and Eaton's automated manual the Autoshift. Rear diffs were usually Meritor units, drive shafts were usually Spicer 1810 series on the main shaft and 1710 series on the jack shaft between the two diffs. Rear suspension was either Hendrickson HAS461 or NeWay. Electrical system was a 24 volt system.

The Iveco PowerStar could be rated for single trailer use all the way to multi-trailer road train applications.

Initially, the first generation PowerStar was very popular with operators who had traditionally only brought North American sourced prime movers, due to the fact the PowerStar could be sourced with the same driveline as their North American Prime Movers, but with the comfort of a European cab. The PowerStar was very well priced also.

The second generation PowerStar, based on the newer European Stralis cab-over-engine design, was initially not available with the North American driveline, but the Iveco Cursor engine and EuroTronic II Transmission only. Because of this the second generation PowerStar was not as popular as the first generation with the American driveline.

However, from 2010 the Cummins ISX engine was again made available with coupled to the EuroTronic II 16 speed transmission, alongside the Iveco Cursor engine in the model line up.

Iveco Strator

A European version of the PowerStar is built in the Netherlands. These trucks are rebuilt Iveco Stralis, designed to meet European safety rules. There are some small exterior differences between the Strator and the PowerStar. It is the only Iveco heavy-duty truck with a bonnet currently sold in Europe.

Motorsport
Dutch driver Gerard de Rooy won the 2012 and 2016 Dakar Rally using modified Iveco PowerStar trucks. As did the Dutch Janus van Kasteren in 2023.

Conair of Scandinavia. Conair of Scandinavia A/S was a Danish charter airline based at Copenhagen Airport. It merged with Scanair to establish Premiair in 1994.

History

Conair was founded by the Scandinavian charter pioneer Simon Spies in 1965. The fleet was from scratch old Douglas DC-7s, which were taken over from Flying Enterprise. Around 1970, Conair got in to the "jet age", and bought second-hand Boeing 720Bs from Eastern Air Lines instead. In autumn of 1987, two Conair Boeing 720s had their nose gear cracked during otherwise normal landings in Salzburg, Austria and Rome, Italy. The fleet was already set to be renewed to second-hand Airbus A300B4s. But after the two incidents the changing of the fleet became a very urgent issue.

After the death of Simon Spies, his rather new wife and former secretary Janni Spies got ahead of the whole Spies corporation (where the traveling agency Spies rejser was included) and she employed her brother, a former carpenter, as general manager.

They soon ordered six new Airbus A320s at the same time as the Gulf War occurred. In the aftermath of the war, a sudden drop in numbers of flight passenger worldwide was a factor (which among other things) led to the bankruptcy of Pan Am. Conair and the Spies traveling agency were saved (almost as a Danish national treasure due to the huge popularity for the former "charter-king", the deceased Simon Spies) by banks, and Janni Spies and her staff were replaced. On 1 January 1994, Conair merged with a Swedish charter airline Scanair, forming a new carrier, Premiair. Today, the airline still operates under the new name Sunclass Airlines, still having its base at Copenhagen Airport.

Operations
Conair primarily flew tourists from the Spies traveling agency, but also served several other travel agencies. The vast majority of flights had their destinations in the Mediterranean area but also at Canary Islands, Gambia, London, Rome and Paris. Beside their main base at Copenhagen, flights also departed from Billund Airport and Stockholm Arlanda Airport.

Fleet
Over the years, Conair of Scandinavian operated the following aircraft:

Fram (bicycle company). Fram (Swedish for Front or Forward) was a Swedish bicycle manufacturer. Fram dated back to 1897 and was manufactured in Uppsala, Sweden until the early 1970s . The company B. Bernh. Oberg & Co. was founded by Bernhard Oberg in 1897 and began manufacturing bicycles similar to competitor Nyman companies . The name probably came from Fridtjof Nansen's ship of the same name. In 1905 took over the production of AB Josef Eriksson's Bicycle Factory (later AB Joseph Erickson).  

In 1932 the company was purchased by the Industrial Company of Helsingborg, which manufactured King bike brand. In 1955 the company changed its name to the bicycle factory Fram. Two years later made it a three-wheel micromobile, as final assembly factory in Helsingborg, but demand was poor. Instead it was for some time sales agents for the German three-wheelers Messerschmitt and Heinkel. In 1973 production was moved almost entirely to Helsingborg.  

The bikes now being called Front-King, and faded away completely during the 1980s. Bernhard Oberg & Co. had offices at Svartbäcksgatan 14 Uppsala. Josef Eriksson came to take over a team building at Österplan which the factory was to last from 1917 until 1960 when a new facility at Verkstadsgatan 8 Bolandsområdet near Uppsala was introduced. After that the production left Verkstadsgatan came some frame parts that are produced during a period in Wellington near Uppsala. 

The old factory building, or "Joffe" as it was called, at Österplan remains and now houses theater operations. Likewise is the more modern factory building at Verkstadsgatan eight remaining houses and engineering companies. 

Monark Crescent, who took over Fram-King in the early 1980s, has occasionally used King brand name. However, the Fram brand name belongs to history.

Yram. Marcel Louis Forhan (alias Yram) (November 1884 – 1 October 1927) was a French electrical engineer who specialized in the electrical installations of trams and TSF stations and an occult writer. He owes his notoriety to a metaphysical trilogy published in many countries.

Early life 

Marcel Louis Forhan was born on November 17, 1884, in Corbeil-Essonnes, France. Son of Louis Forhan and Céline Berthelot, he had a brother, Julien, and two sisters, Marcelline and Léa.

Career
He worked as an electrical engineer for the French company of tramways and electric lighting which sent him to settle, shortly before the First World War, in the French concession of Shanghai.  This was in order to install an important power station there, which provided electricity on which French Trams depended. He also participated in the installation of TSF broadcasting stations.

Occultism

His books relate experiences lived outside the physical body using a technique named astral projection. The deductions he reaches found in his eyes a new paradigm, perhaps utopian, capable of creating a more equitable society which would no longer fear the advent of death and act in a philanthropic way.

Some of its themes are common (but not specific) to Theosophy (the notion of karma, astral body, successive higher planes and spiritual evolution) and to representative authors such as Arthur Edward Powell.

His books describe several out of body experiences.

Personal life and death
His fiancée, Suzanne Garbe (Born February 4, 1892, Guise), joined him in China from Egypt where she lived with her mother. They got married on August 17, 1914, in Shanghai. In China, they had three children, Max (born in 1915), Marcel-André (born in 1919) and Robert (born in 1920).

In 1927, he contracted dysentery which developed into sepsis. Forhan died on October 1, 1927, in Shanghai.

Mitsubishi MC-1. The Mitsubishi MC-1 was a 1920s Japanese single-engined biplane airliner designed and built by the  Mitsubishi Aircraft Company.

Design and development
In 1927, the Japanese Department of Communications launched a competition to design and build an indigenous passenger transport aircraft. Mitsubishi's design to meet this requirement was based on its Mitsubishi B1M torpedo bomber, using the wings of the earlier aircraft combined with a new fuselage. The MC-1 was large three-bay biplane powered by a  Armstrong Siddeley Jaguar radial engine and it had an open cockpit behind the wings for the pilot and room for four (some sources say eight) passengers in an enclosed cabin in the forward fuselage. The MC-1 had a fixed conventional landing gear but could also be fitted with twin floats.

The MC-1 was completed in April 1928, and was evaluated against the other two competitors, the Aichi AB-1 and Nakajima N-36, both of which were also biplanes.  No production followed of any of the aircraft, as they were considered obsolete compared with foreign types, and the state-owned airline Japan Air Transport (Nihon Koko Yuso KK) ordered Fokker Universal monoplanes instead.

Operational history
Although no production of the MC-1 followed, the prototype was used to operate an experimental air service between Tokyo and Osaka sponsored by the Asahi Shimbun newspaper between June 1928 and April 1929, and then by Japan Air Transport for services in Korea until May 1930.  It was then used as a seaplane flying sightseeing flights around the north coast of Honshu until 1938.

Alexander Dennis Enviro350H. The Alexander Dennis Enviro350H was a hybrid-electric powered single-decker bus manufactured by Alexander Dennis between 2010 and 2013. It was the first Alexander Dennis bus model which was only sold as a hybrid-electric vehicle, the Enviro200H, 400H and 500H models having diesel-powered equivalents.

The Enviro350H has its powertrain located at the nearside of the rear overhang, similar with the full-low-floor buses in Europe. It can be equipped with BAE Systems' HybriDrive series-hybrid system with a Cummins ISBe engine as generator.

In 2014, Alexander Dennis announced the virtual electric version known as the Enviro350VE, which can be powered by wireless charging in addition to the hybrid power system. However, there were no confirmed orders of this type and it was subsequently replaced by variants of ADL's newer Enviro200 MMC.

Operations 
The bus was targeted for sale in Continental Europe and Australia. The first bus with Tata Hispano Habit bodywork was unveiled at the FIAA 2010 trade show in November 2010, this bus and another similar vehicle were sold for use in the Canary Islands.

Another was bodied in Australia by Custom Coaches and evaluated by the State Transit Authority for 14 months from March 2011. It was later purchased by Torrens Transit.

Stagecoach East Scotland purchased 22 for use at its Bluebird (13) and Perth (9) subsidiaries. All 22 now operate out of Aberdeen's Tullos depot with Stagecoach Bluebird. First Essex purchased four and Transports Metropolitans de Barcelona, Spain 12.
