Hilbert curve scheduling. In parallel processing, the Hilbert curve scheduling method turns a multidimensional task allocation problem into a one-dimensional space filling problem using Hilbert curves, assigning related tasks to locations with higher levels of proximity. Other space filling curves may also be used in various computing applications for similar purposes.

The SLURM job scheduler which is used on a number of supercomputers uses a best fit algorithm based on Hilbert curve scheduling in order to optimize locality of task assignments.

Peripheral bus. In computing, a peripheral bus is a computer bus designed to support computer peripherals like printers and hard drives. The term is generally used to refer to systems that offer support for a wide variety of devices, like Universal Serial Bus, as opposed to those that are dedicated to specific types of hardware. Serial AT Attachment, or SATA is designed and optimized for communication with mass storage devices. 

This usage is not universal, some definitions of peripheral bus include any bus that is not a system bus, including examples like PCI. Others treat PCI and similar systems as a third category, the expansion bus.

MIL-STD-461. MIL-STD-461 is a United States Military Standard that describes how to test equipment for electromagnetic compatibility.

The United States Department of Defense issued MIL-STD-461 in 1967 to integrate electromagnetic compatibility into the research and development stage for defense communications technology. Various revisions of MIL-STD-461 have been released.

Many military contracts require compliance to MIL-STD-461E. The latest revision (as of 2015) is known as "MIL-STD-461G". While MIL-STD-461 compliance is technically not required outside the US military, many civilian organizations also use this document. In 1999, MIL-STD-462 was combined with MIL-STD-461D into MIL-STD-461E.

Albert S. Janin. Albert Stanley Janin (1881–1931) was an American inventor of a hydro-airplane in 1907, independently of Glenn Curtiss. Even though Janin had had a prior patent, he lost in prolonged patent litigations to Curtiss on the grounds that Janin's designs did not disclose sufficient detail. Janin did win his claim first but then lost it on appeals. He was also credited with invention of the "inflammable [flammable] bullet" used during that war, and a catapult used to launch planes from ships. During World War I, he donated many of his patents to the government, for which he was honored by President Woodrow Wilson.

Edwin Edward Hunnisett. Serjeant Mechanic Edwin Edward Hunnisett (1896 – 30 June 1918) was a World War I British aviator who was shot down by German flying ace Hans Goerth.

Background
Edwin Hunnisett was born in 1896 in Newhaven, East Sussex, England. He was the son of Benjamin Hunnisett and his wife Harriet Sarah Daniels. His father also served in World War I, receiving the Victory Medal, British War Medal, and the 1914 Star and Clasp.

Military career
Edwin Hunnisett enlisted in the Royal Naval Volunteer Reserve on 6 January 1913. He served with the Howe Battalion of the Royal Naval Division from 22 August 1914 to 27 July 1915. On 18 September 1915, he was invalided back to the United Kingdom after development of a hernia. However, Hunnisett was transferred to Dunkirk (Dunkerque) in Nord, France on 16 February 1916. As a private, he flew with Australian Flight Lieutenant Charles Jarvis Moir. However, the Australian was killed in action on 10 May 1917 while flying N6185 'A' on an escort mission. In the spring of 1918, Hunnisett became a member of the No. 217 Squadron of the Royal Air Force. By June 1918, the aviator had the rank of serjeant mechanic. His aircraft was an Airco de Havilland DH.4 with serial number A8013. Edwin Hunnisett received the Victory Medal and the British War Medal.

Death

On the evening of 30 June 1918, Edwin Hunnisett's Airco de Havilland DH.4 (A8013) engaged in aerial combat with the Albatros D.Va with serial number 7167/18 piloted by German flying ace Hans Goerth. The plane was shot down over Mariakerke, Belgium by the Vizeflugmeister of Marine Feld Jasta III, and the serjeant mechanic, who had been acting as observer, died in the conflict. The downing of the plane was the first of seven aerial victories for Vizeflugmeister Goerth. Edwin Edward Hunnisett is commemorated on a headstone at Newhaven Cemetery in Newhaven, East Sussex, England. However, the British aviator is also represented on a second cenotaph, the Arras Flying Services Memorial, at the Faubourg d'Amiens Cemetery in Arras, Pas-de-Calais, France. There are two additional memorials which acknowledge the contribution of Serjeant Mechanic Hunnisett. One is the Newhaven War Memorial, which is located in the park adjacent to Newhaven Harbor in Newhaven, East Sussex, England. The obelisk records 127 names of the area's fallen from the Great War. The last memorial is in Saint Michael and All Angels Anglican and Methodist Church in Newhaven, East Sussex. It records 90 names of the parish's fallen, in the chronological order of their deaths.

Aeromarine EO. The Aeromarine EO was a light sport flying boat that was built in the mid-1920s.

Design and development
The Aeromarine EO was designed as an updated replacement of the Aeromarine Model 44 for the customer Earl Dodge Osborn. Osborn was a former accountant for Aeromarine, assistant editor of Aviation magazine and future founder of Edo Aircraft Corporation. The aluminum hull was scaled down from the Aeromarine AMC design, offering advantages in durability, weight and the inability to become waterlogged.

The EO was an open-cockpit aluminum-hulled biplane seaplane with a single tractor engine center mounted in a nacelle on the top wing which also housed the fuel tank and oil tank. The upper wing was staggered well forward of the lower wing. The wings were constructed with spruce I-beam spars and ribs with aircraft fabric covering. The hull was built with four watertight compartments. The tip floats were all-aluminum. A cross-through tube accepted a wheel assembly for ground movement.

Operational history
The first flight tests were performed by Osborn in June 1924. The sole EO was used for demonstration flights for the EDO company. It then transferred ownership several times with a planned flight to Puerto Rico. It was listed as "Washed Out" at Cape May, New Jersey and its registration was cancelled on 21 January 1932.

MDZ Shield. The MDZ Shield (or Minimize Danger Zone Shield) is a safety device for school buses, consisting of a two-piece polyurethane guard that encloses the upper wheel well opening and covers the gap in front of the right rear wheels, designed to deflect a person out of the path of the wheels in order to prevent injury or death. The "danger zone," which the shield acts to mitigate, refers to the area extending 10 feet to the front, rear and sides of the school bus, where children are at most risk of being hit by passing vehicles or by their own bus. Invented and developed by Mark B. Barron of Public Transportation Safety International, developer of the similar S-1 Gard for transit buses, and distributed by The C.E. White Company, the MDZ Shield first came to market in 2011.

Statistics
On average, fatal injuries occur outside the school bus at a rate of four times those occurring inside the bus; besides being struck and killed by other vehicles, the greatest number of child fatalities occur by the right rear tire of the student’s own bus. Since the 1970-1971 school year, the Kansas State Department of Education has compiled an annual National School Bus Loading and Unloading Survey, detailing fatalities occurring in the danger zone surrounding school buses on which an MDZ Shield is not present. According to the reports, from the 2004-2005 through 2010-2011 school years, there have been 48 fatalities involving the school bus while loading and unloading. Of those, half were caused by the right rear wheels. Of all fatalities involving the rear wheels, 83% took place on the right side of the bus. The reports have shown that in a majority of cases involving the wheels, children first incur injuries by coming in contact with the tire before being propelled underneath the bus wheels. In addition to the 10 feet surrounding the school bus, there is typically an approximately 2 foot vertical gap in front of the rear wheels between the undercarriage and the ground, in which a child is at increased risk of coming in contact with the tire.

Design
The MDZ Shield is mounted around the right real wheel (or wheels), and consists of two pieces: a wheel shield, which covers the wheel well opening, and a lower tire safety guard, which mounts to a receiver on the undercarriage of the bus and sits approximately four inches from the ground. The shield can deflect a child out of the path of the school bus, thereby minimizing the extent of injury in the danger zone.

Dimethyl trisulfide. Dimethyl trisulfide (DMTS) is an organic chemical compound and the simplest organic trisulfide, with the chemical formula CH3SSSCH3. It is a flammable liquid with a foul odor, which is detectable at levels as low as 1 part per trillion.

Occurrence
Dimethyl trisulfide has been found in volatiles emitted from cooked onion, leek and other Allium species, from broccoli and cabbage, as well as from Limburger cheese, and is involved in the unpalatable aroma of aged beer and stale Japanese sake. It is a product of bacterial decomposition, including the early stages of human decomposition, and is a major attractant for blowflies looking for hosts. Dimethyl trisulfide along with dimethyl sulfide and dimethyl disulfide have been confirmed as volatile compounds given off by the fly-attracting plant known as dead-horse arum (Helicodiceros muscivorus). These flies are attracted to the odor of fetid meat and help pollinate this plant. DMTS contributes to the foul odor given off by the fungus Phallus impudicus, also known as the common stinkhorn. DMTS causes the characteristic malodorous smell of a fungating lesion, e.g., from cancer wounds, and contributes to the odor of human feces.

DMTS can be synthesized by the reaction of methanethiol with hydrogen sulfide (in the presence of copper (II)) and with sulfur dichloride, among other methods:

2 CH3SH + SCl2 → CH3SSSCH3 + 2 HCl

Chemical reactions
On heating at 80 °C, DMTS slowly decomposes to a mixture of dimethyl di-, tri-, and tetrasulfides. The reactivity of DMTS is related to its weak sulfur-sulfur bond (ca. 45 kcal/mol). Dimethyl tetrasulfide, which is thermally more reactive than dimethyl trisulfide, has a still weaker (central) sulfur-sulfur bond (ca. 36 kcal/mol). Oxidation of DMTS by meta-chloroperoxybenzoic acid (mCPBA) gives the corresponding S-monoxide, CH3S(O)SSCH3.

Uses
Trap baits containing dimethyl trisulfide have been used to capture Calliphora loewi and other blowflies. Dimethyl trisulfide has been found to be an effective cyanide antidote in a rodent model for cyanide poisoning both against subcutaneous potassium cyanide and inhaled hydrogen cyanide, converting cyanide to much less toxic thiocyanate. It is suggested that dimethyl trisulfide can be used in a mass casualty cyanide exposure setting. In conjunction with these studies, the LD50 of dimethyl trisulfide in CD-1 mice was found to be 598.5 mg/kg, which may be compared to the LD50 of potassium cyanide of 8.0 mg/kg.

Cottbus-Großenhain Railway Company. The Cottbus-Großenhain Railway Company (, CGE) was a railway company in Prussia. It owned rail links between Großenhain, Cottbus and Frankfurt (Oder).

History 

It was founded in 1868, with the Leipzig–Dresden Railway Company (Leipzig-Dresdner Eisenbahn-Compagnie) holding a third of the capital, as it had hoped for additional traffic as a result of the construction of the new line. They also took over its management when the 80 km long Cottbus–Senftenberg–Großenhain line opened on 20 April 1870. The first Director of the CGE until 1876 was Karl Eduard Zachariae von Lingenthal. The company was based in Cottbus.

The 71 km long extension of the main line to the northeast of Cottbus via Grunow to Frankfurt (Oder) was opened to traffic on 31 December 1876.

From 1 June 1874. the CGE decided—at the request of the Prussian government—to operate its own line, as well as the newly opened Upper Lusatian Railway Company (Oberlausitzer Eisenbahn-Gesellschaf). From 1 July 1878 it also managed the Ruhland–Lauchhammer (Ost) branch line.

Since the traffic of the CGE was well developed, the Prussian government decided to acquire the company. It took over the administration and operation of the railway on 1 May 1882 and ownership on 1 September 1883. The CGE was dissolved.
