Plurality (company). Plurality Ltd. is an Israeli semiconductor company, the developer of the HyperCore technology and the HAL (HyperCore Architecture Line) multi-core processor. The company is a member of the Multicore Association.

HyperCore 
Plurality develops the HyperCore CPU technology, which is a MIMD 32-bit RISC based multi-processor on a single chip, and contains from 16 to 256 cores. HyperCore technology supports executing both fine-grained and coarse-grain parallelism due to its special hardware Synchronizer/Scheduler, shared memory and task based programming model.

The HyperCore technology's synchronizer/scheduler (patented, see below also) eliminates the need of repeatedly executing a special kernel program controlling and deciding which task (or thread) to currently assign and execute on a given processor. The ability to synchronize tasks in hardware allows the processor to support fine-grained programs and to achieve almost a linear speedup. Fine grained programs can only be executed when tasks' duration is significantly shorter than the overhead time introduced by the scheduler. The HyperCore's shared memory (patent pending) avoid the coherency problem and keep a single memory space for all cores in the system thus simplifying the programming model significantly.

Patents

Synchronizer/scheduler 
Dr. Nimrod Bayer and Dr. Ran Ginosar, two of Plurality's founders, received United States Patent 5202987 ("A High Flow-Rate Synchronizer/Scheduler for Multiprocessors") for the company's core technology on April 13, 1993. The patent has been cited by more than 30 subsequent patents. The patent abstract is as follows:

"A high flow rate synchronizer/scheduler apparatus for a multiprocessor system during program run-time, comprises a connection matrix for monitoring and detecting computational tasks which are allowed for execution containing a task map and a network of nodes for distributing to the processors information or computational tasks detected to be enabled by the connection matrix. The network of nodes possesses the capability of decomposing information on a pack of allocated computational tasks into messages of finer sub-packs to be sent towards the processors, as well as the capability of unifying packs of information on termination of computational tasks into a more comprehensive pack. A method of performing the synchronization/scheduling in the multiprocessor system of this apparatus is also described."

Electric dragbike. An electric dragbike is an electric motorcycle used for drag racing.

Electric dragsters have come of age with new developments in battery and motor technology. Electric motors powered by lithium cells can deliver power-to-weight ratios similar to high performance gasoline engines. Drag races last around ten seconds so battery range is not an issue. A number of electric dragbikes and dragsters (cars) are competing with Top Fuel classes.  Electric drag racing records are listed at NEDRA.

Batteries
Electric dragbike tend to use lithium-ion or nickel-metal hydride cells due to their higher energy density which means they are less bulky to carry. In addition fewer cells are needed compared to a car as the "payload" of bike and rider is lighter. Typical weights:  rider,  bike excluding battery weight.

Hall XFH. The Hall XFH was an American fighter aircraft built by the Hall Aluminum Company. It was the first fighter with a semi-monocoque metal fuselage.

Development
The XFH was designed in 1927 by Charles Hall. It was a single-bay biplane with N-struts for the fabric-covered wings. Its fuselage was made of steel tubing covered with a watertight aluminum skin, enabling it to float if ditched in the ocean. Also for ditching on water or on land, the landing gear could be jettisoned. Power was provided by a Pratt & Whitney Wasp radial engine. Testing in June 1929 showed poor handling characteristics and performance. During one test flight, the upper wing separated from the aircraft. After repairs, the XFH made test flights from an aircraft carrier. Designated XFH by the Bureau of Aeronautics, it was purchased not for active service, but to study new metal construction techniques.

LFG Roland D.I. The LFG Roland D.I was a fighter aircraft produced in Germany during World War I. It was a single-seat aircraft based originally on the Roland C.II two-seat reconnaissance type. It shared its predecessor's unusual design feature of having a deep fuselage that completely filled the interplane gap, but in comparison, the fuselage was much sleeker. While the C.II's appearance had earned the Walfisch ("Whale"), the D.I became known as the Haifisch ("Shark"). The I-struts that had been used to brace the C.II's wing were replaced by more conventional struts. Other changes to the wing included the removal of stagger from the design and the introduction of slight sweepback.

The prototype flew in July 1916 and was accepted by the Idflieg for military service. Production was interrupted, however, by a fire at the factory after only around twenty machines had been built. When production eventually resumed, it was of the improved Roland D.II.

Variants

LFG WD Two float seaplane version first flown 29 June 1917 and tested at Warnemünde in July.  It was found wanting both in its flight characteristics and the view forward and downwards.  The latter criticism was frequently made of the D.I and its descendants, visibility blocked by engine radiators and the lower wing.modifications were made, but further official testing in September lead to the refusal of a production order.  Modified yet again, the single example ended with the seaplane single-seat fighter school. It is sometimes referred to as the LFG W, though this name is also used for a LFG floatplane version of the Albatros C.Ia.

LFG Roland D.III. The LFG Roland D.III was a fighter aircraft produced in Germany during World War I.

Design and development
The D.III was a further development of the D.I fighter. These machines had a fuselage that completely filled the interplane gap, a design feature intended to improve aerodynamics. However, it also resulted in limiting the pilot's field of vision in the down and forward direction, leading to complaints. LFG attempted to remedy this in the D.III design by introducing a gap between the upper fuselage and the upper wing, braced by cabane struts. The size of the tailplane was also increased.

While this did indeed result in an improvement over the Roland D.II that had preceded it, the performance of the D.III was inferior to that of other contemporary fighters available to the German Army, in particular those produced by Albatros, and the aircraft was therefore only produced in small quantities.

Forward visibility, though better in the D.III than the D.I was still not good and LFG tried to improve it with another variant, the D.V. The fuselage diameter was decreased and the decking forward of the cockpit lowered exposing all of the upper parts of the engine cylinders.  Three were built, one with the Argus engine of the D.II and two with the   Mercedes D.III, another upright 6-cylinder engine.  The visibility was not much improved and the problem was only solved with the LFG Roland D.VII, which used a V-8 engine.

Variants
D.V Lowered fuselage to improve pilot's view.  Three built, one with Argus and two with Mercedes engines.

HMS Viper (1865). HMS Viper was an armoured iron gunboat, the only ship of her class, and the fourteenth ship of the Royal Navy to bear the name.

Design
Designed by the Admiralty, Viper was a half-sister to  and , and all three were built mostly as experimental vessels.  While Viper and Vixen were twin screw vessels, Waterwitch had a water-pump propulsion system.  Vixen was almost identical to Viper, but was of composite construction.

Hull
Viper was an armoured gunboat of the breastwork type.  Her hull was of iron construction, with  of teak backing.  Vertical trunks were provided at the stern to lift the screws clear of the hull, thereby allowing a better hull-form for purely wind-driven sailing.

Propulsion
She was equipped with two sets of 4-cylinder horizontal single-expansion steam engines, each set powering one of her two-bladed, 9 ft diameter Maudslay & Griffiths screws.  In total she developed an indicated 696 horsepower, sufficient for a top speed of . Steam was provided by two Maudslay iron fire-tube boilers with six furnaces.

Sail plan
She was equipped with a barquentine rig, but in 1873 all masts, rigging and upper deck obstructions were removed after the decision for Vixen and Viper to remain permanently in Bermuda.

Armament
Viper was armed with two 7-inch (6½-ton) muzzle-loading rifled guns and two 20-pounder breech-loading rifled guns.  One of Vixen or Viper's 7-inch guns was displayed on the waterfront at St Georges as recently as 1991.

Construction
Viper was ordered from J & W Dudgeon of Cubitt Town on 22 March 1864 and laid down the same year.  She was launched on 21 December 1865 and commissioned in 1867 for comparative trials.  Her total cost was £51,127.

Career
Vixen, Viper and Waterwitch conducted comparative trials at Stokes Bay in the Solent during the late 1860s.  Although turning ability was impressive, none of the ships attained more than  in an era when  could achieve .  Furthermore, Vixen was nearly lost in the Irish Channel during a winter gale in 1876, making them unsuitable for the open sea under steam or sail.  Vixen and Viper were towed to Bermuda in 1868 where the geography favoured the use of steam-powered rams.

In July 1869 both ships were employed to bring the floating dock Bermuda from The Narrows to the dockyard. 1873 saw the loss of all rigging, masts and upperdeck equipment, and this must have helped her to survive the 1878 hurricane which caused serious damage to the floating dock and other dockyard facilities.

Fate
Viper was reduced to harbour service in 1890, was converted to a tank vessel in 1901 and was sold in 1908.

Paul Daimler. Paul Daimler (13 September 1869 – 15 December 1945) was a German mechanical engineer who designed automobiles. He was the eldest child of Gottlieb Daimler who founded Daimler-Motoren-Gesellschaft and (with Wilhelm Maybach) invented the petrol engine.

After studying at the Technische Hochschule Stuttgart, he worked in his father's factory in Cannstatt. On 10 November 1885 he travelled with his father in the "riding car"—the world's first motorcycle—from Cannstatt to Untertürkheim. In 1902, Paul was sent to the general partners of Austro-Daimler, where he became the technical director. In 1903, he designed an armoured car. From 1907 to 1922 he was Technical Director of Daimler-Motoren-Gesellschaft Untertürkheim, Sindelfingen and Berlin-Marienfelde. On 1 July 1923, he joined Horch, part of Argus Motoren Gesellschaft and made a name for himself there as a developer in the department of motor aircraft engines, remaining until 1928.

Examples of his work include the hydraulic valve lifters, which he introduced in 1931.

LFG V 13. 

The LFG V 13 Strela (named for the Strelasund off Rügen) was a seaplane airliner produced in small quantities in Germany in the early 1920s. It was a conventional, three-bay biplane with an enclosed cabin for four passengers. The original design featured twin pontoons, but a landplane version was developed as the V 130.

The V 13s were operated by Luft-Fahrzeug on its Hamburg-Stettin-Danzig and Stettin-Swinemünde-Stralsund routes. These services were later shared by V 13s operated by Luftverkehr Pommern and later were absorbed into Deutsche Luft Hansa. In Norway, Norske Luftruter operated two second-hand V 13s until the late 1920s.

New South Wales D53 class locomotive. The D53 class was a class of 2-8-0 steam locomotives built for the New South Wales Government Railways of Australia.

History

This class of locomotive was designed by the New South Wales Government Railways as an improved version of the T class. All the coupled wheels had flanges and a certain amount of side movement was given to the middle pairs with a laterally operating knuckle joint being provided in the middle section of the coupling rods.

Clyde Engineering delivered the first locomotive in April 1912 and by November 1917, a total of 190 were in service. Most were fitted with superheaters when built and some fitted at a later date. There was a problem with the locomotives being unbalanced, causing speed restrictions to be imposed to avoid rough riding and track damage. Following further investigations, 24 of the class received balanced coupled wheels and these were permitted to operate at higher speed on mail and fruit trains.

When introduced, most of the class were fitted with a standard bogie tender, similar to those attached to the 50 class, although some saw service with large capacity "Wampu" tenders. In the later period of their lives, the majority were fitted with larger turret type tenders. In later years some were used as heavy shunting locomotives and from 1963 on some of these had automatic couplers fitted to the front.

Following the removal of the knuckle joints from the coupling rods, flanges from the second coupled and driving wheels and the fitting of boilers standard for 50 class; 53 class and 55 class, they became most useful locomotives.

The 24 not fitted with superheaters were scrapped in the 1930s. The first superheated example was withdrawn in January 1957 with the fleet down to 39 by July 1969 with the last withdrawn in January 1973. 

The Commonwealth Railways used the design of these locomotives for their 26 strong KA class for the Trans-Australian Railway.

Preservation
Three have been preserved:

Locomotive 5461 is fitted with the last "Wampu" style tender and was known as 1174 in the pre-1924 numbering scheme. 1174 was known to be an exceptionally bad steamer and was the subject of many poems.

Kaiwera Downs Wind Farm. The Kaiwera Downs Wind Farm is a wind farm in the Southland region of New Zealand. It is consented to have a maximum capacity of 240MW and use up to 83 turbines. Originally proposed by Trustpower, it is now owned and operated by Mercury Energy. The 10 turbine, 43MW stage 1 of the project was opened in November 2023.

The New Zealand Ministry for Culture and Heritage gives a translation of "hot food" for Kaiwera.

Location and Resource
The wind farm is located about 15 kilometres south-east of Gore, within an area of . Access to the site from the port at Bluff is "considered excellent".

The prevailing south-west/ westerly winds blow with an average wind speed of 8.7 – 8.9 m/s.

Construction
The project received resource consent in June 2008. In September 2018 Tilt said that the development was waiting for favourable market conditions. In June 2021 Tilt announced the project was being acquired by Mercury Energy. In June 2022 Mercury began talks with the local community over the wind farm.

Stage 1 
Installation of an initial ten turbines totalling 43MW of generation is expected to start in October 2022. Earthworks began in the first week of October 2022. A sod-turning ceremony was held in November 2022. As of February 2023, Mercury say they expect all turbines to be operational by October 2023. The first turbines arrived in April 2023, and were transported to the site during May and June. As of July 2023, two of ten turbines had been erected, and the wind farm was expected to be complete by October. As of mid October 8 of 10 turbines are operational and stage 1 of the project is on track to be completed by the end of October. The wind farm was officially opened on 20 November.

Stage 2 
Mercury is building stage 2 of the project starting in June 2024 with first generation coming on stream by mid-2026 and completion by mid-2027. They are building an additional 155MW of capacity.  In June 2023 they received approval to amend their resource consent. This change reduces the total number of turbines for the project from 83 to 66 but allows the remaining turbines to be built with an additional 20 meters of height, a maximum blade tip height of 165m. Mercury say this will help reduce stress on the blades and increase their lifespan.

Construction of stage 2 began in July 2024.

Transmission 

Power from Stage 1 is exported via a new  33,000-volt line to Transpower's Gore substation.

Power from Stage 2 will be exported via a short new 220Kv transmission line connecting to Transpower’s North Makarewa to Three Mile Hill Line.
