Nokia N1
The Nokia N1 is a tablet developed by Nokia, running on Android 5.0. Unveiled on 18 November 2014, it is Nokia's first mobile device since the sale of its original mobile phone business to Microsoft earlier in the year. It was released in January 2015. Development According to Sebastian Nyström, Head of Products Business Nokia Technologies, work on the tablet began on 28 April just days after the acquisition of its former mobile phone division by Microsoft. The unveiling of the N1 came shortly after an announcement on 17 November 2014 by Nokia Technologies President Ramzi Haidamus, that the company would begin to contract the manufacturing of future Nokia products to third-party companies, to ensure a continued consumer presence for the "valuable" Nokia brand. As part of the sale, Nokia is subject to non-compete clauses forbidding it from producing Nokia-branded smartphones until the end of 2015, and feature phones for 10 years after the closure of the Microsoft sale, but ...

N-1 Contingency Planning
In an electrical grid, contingency is an unexpected failure of a single principal component (e.g., an electrical generator or a power transmission line) that causes the change of the system state large enough to endanger the Security (electrical grid), grid security. Some protective relays are set up in a way that multiple individual components are disconnected due to a single fault, in this case, taking out all the units in a group counts as a single contingency. A scheduled outage (like maintenance) is not a contingency. The choice of term emphasizes the fact that a single fault can cause severe damage to the system so quickly that the operator will not have time to intervene, and therefore a reaction to every single fault has to be defensively pre-built into the system configuration. Some sources use the term interchangeably with "disturbance" and "fault". Contingency analysis The contingency analysis application periodically runs on the computers at the operations centers pro ...

N1 (rocket)
The N1 (from , "Carrier Rocket"; Cyrillic: Н1) was a super heavy-lift launch vehicle intended to deliver payloads beyond low Earth orbit. The N1 was the Soviet counterpart to the US Saturn V and was intended to enable crewed travel to the Moon and beyond, with studies beginning as early as 1959. Its first stage, Block A, was the most powerful rocket stage ever flown for over 50 years, with the record standing until Starship's first integrated flight test. However, each of the four attempts to launch an N1 failed in flight, with the second attempt resulting in the vehicle crashing back onto its launch pad shortly after liftoff. Adverse characteristics of the large cluster of thirty engines and its complex fuel and oxidizer feeder systems were not revealed earlier in development because static test firings had not been conducted. The N1-L3 version was designed to compete with the United States Apollo program to land a person on the Moon, using a similar lunar orbit rendezvou ...

VR Class Pr1
VR Class Pr1 (original classification N1, nickname ''Paikku'', from Finnish “paikallinen”, local) was a tank steam locomotive for local passenger services of Finnish railways. Ordering and delivery In the 1920s, VR was concerned about the low power and speed of their existing class Vk1-3 class locomotives that were used in local services, especially on the Helsinki commuter rail services. A decision was reached to order a new and powerful, by standards of that time, local traffic locomotive from Hanomag with the intention of licence manufacture of more units by Finnish locomotive works. At the same time, a shunting locomotive based on a similar design, Vr3, was also ordered. The classes share many parts, including as frames, boilers and spaces for coal, but wheel arrangement, domes and top speed are very different because of their completely different roles. The locomotive was of tank design with small coal bunker in the rear, which limited operational range. The first batc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SECR N1 Class
The SECR N1 class was a type of 3-cylinder 2-6-0 ('mogul') steam locomotive designed by Richard Maunsell for mixed traffic duties, initially on the South Eastern and Chatham Railway (SECR), and later operated for the Southern Railway (SR). The N1 was a development of the basic principles established by the Great Western Railway's (GWR) Chief Mechanical Engineer (CME) George Jackson Churchward and by Maunsell's previous N class design.Scott-Morgan (2002), p. 18 The N1 prototype was the result of modifications made to N class No. 822 during construction in 1922. The locomotive became operational in 1923 and used parts interchangeable with other Maunsell locomotive classes. The prototype N1 was the only member of the class constructed before the SECR became part of the Southern Railway at the Grouping in 1923, and featured Holcroft conjugated valve gear, Holcroft's experience in this field later aided in the development of the Gresley conjugated valve gear which ...

PRR N1s
The Pennsylvania Railroad (PRR) N1s was a class of 2-10-2 "Santa Fe" steam locomotives built for the Pennsylvania's Lines West. 60 engines were built between December 1918 and November 1919, and worked heavy mineral freight to and from ports on the Great Lakes until their retirement in the late 1940s. All examples were scrapped by 1950. Overview The 2-10-2 wheel arrangement, ten driving wheels with a two-wheel leading truck and a two-wheel cast KW-pattern trailing truck under a large Belpaire firebox, suited the N1s' intended purpose well. They were drag freight engines, designed to haul heavy freight up the 0.3% grade leading out of the PRR's "Lake ports," and were rated at 6000 tons (5443 tonnes) on these relatively easy grades. The design was developed by the PRR's Fort Wayne Shops and orders were placed with Alco (Brooks) (35 locomotives) and Baldwin (25 locomotives) for a total of 60; the first Alco locomotive was delivered in December 1918, with the remainder arriving duri ...

GNR Class N1
The Great Northern Railway (Great Britain), Great Northern Railway (GNR) Class N1 was an 0-6-2T side tank steam locomotive designed by Henry Ivatt and introduced in 1906. They were all withdrawn from service between 1947 and 1959. None have survived. Most of the class were fitted with Condensing steam locomotive, condensing apparatus and worked in the London area, from King's Cross and Hornsey depots, on empty coach trains, and on cross-London exchange freight trains. In 1914, Crewe Works built an armoured train which used a Class N1 engine. The engine was covered by a 14mm steel plate, and featured observation apertures to the front and side, closed by sliding steel shutters. Two of the Ivatt tank engines No. 1587 and No. 1590 were loaned to Crewe to be fitted with armor plating and were named HMT Norna and HMT Alice respectively. They were sold back to the LNER in 1923 and had their armor plating removed. References * * *Ian Allan ABC of British Railways Locomotives, 19 ...

Northrop N-1M
The Northrop N-1M (''Northrop Model 1 Mockup''), also known by the nickname "Jeep", is a retired American experimental aircraft used in the development of the flying wing concept by Northrop Aircraft during the 1940s. Design and development Jack Northrop became involved with all-wing aircraft designs in the late 1920s, with his first flying wing research prototype being built in the 1928–1930 time period. That first prototype, registered X-216H, had evolved from earlier design studies but was not yet a true flying wing as it retained a tail unit comprising twin rudders with a single horizontal stabilizer running between them; both rudders were connected by twin booms to the thick, all-wing blended fuselage. The aircraft had an open cockpit in the center wing section and single, rear-facing, pusher propeller connected to a Menasco Cirrus inverted-four piston engine blended into the all-wing shape. X-216H was first flown in 1929 with Edward Bellande at the controls; the airc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop N-1
The Northrop N-1 (''Northrop Model 1'') was a projected flying wing medium bomber designed by Jack Northrop. Design and development The N-1 was a development of an earlier flying wing bomber concept from 1937, when Jack Northrop worked for Douglas Aircraft Company at El Segundo, California. This concept featured a fuselage that protruded forward of the leading edge of the wing, two pusher propellers, and vertical stabilizers on the tips of the wings. Its engines were never specified, but its defensive armament was to consist of a nose and tail turrets. A wind tunnel model of the concept was built and tested, but the project was abandoned shortly after Northrop left Douglas. Northrop continued work on the bomber after he formed his own company, Northrop Corporation, in 1939. In response to the United States Army Air Corps' XC-219 specification, which called for a new high-altitude medium bomber, Northrop made several major changes to the design, and gave it the model number N-1. ...

Naval Aircraft Factory N-1
The Naval Aircraft Factory N-1 or Davis Gun Carrier was a 1918 maritime patrol aircraft built by the Naval Aircraft Factory (NAF), the in-house aircraft production arm of the United States Navy. A floatplane of biplane configuration with a single Liberty L-12 engine driving a pusher propeller, it was the first aircraft to be both designed and built by the NAF, and was designed to carry the Davis gun, the first recoilless gun A Recoilless rifle ( rifled), recoilless launcher ( smoothbore), or simply recoilless gun, sometimes abbreviated to "rr" or "RCL" (for ReCoilLess) is a type of lightweight artillery system or man-portable launcher that is designed to eject some .... The first prototype crashed during its maiden flight due to poorly designed floats but was rebuilt. However, the aircraft's performance did not meet expectations, and navy leaders canceled the program after 2 of the 4 prototypes were subsequently damaged in serious crashes.

Caproni Campini N
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era and the Società Italiana Caproni went out of business in 1950. Many of the company's former assets wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
