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 ...
