Nuclear Propulsion
In 1954, atomic energy became available with the commissioning of the USS Nautilus. Because a nuclear reactor did not require any oxygen, a single power plant was sufficient for both surface and underwater operation. Furthermore, a very small amount of nuclear fuel (enriched uranium) provided energy for a very long period of time, allowing a nuclear submarine to travel completely underwater at high speeds indefinitely.
This change was revolutionary. In a typical submarine attack before the advent of nuclear technology, the submarine would approach a target on the surface to avoid draining its batteries, and would only dive just before the target was sighted. Underwater entries had to be made at very slow speeds, probably no more than 2-3 knots, to avoid wasting battery power. Submarine commanders had to conserve battery charge until after the attack and use full underwater power (and perhaps at speeds of 7-10 knots) to avoid counterattacks. Even then, a full battery charge would only last about 1-2 hours at top speed. The need to conserve battery power meant that diesel-electric submarines had to approach their target as quietly and slowly as possible, meaning they could not attack most fast surface warships such as aircraft carriers or battleships.
For these reasons, diesel-electric submarines remain stealthy yet effective platforms, operating very quietly and conserving energy for escape after an attack. Since electric motors are quieter than nuclear units (and can even be shut off temporarily), they are sometimes proposed as anti-submarine vessels that silently wait for prey in areas where enemy submarines are known to pass. AIP offers the possibility of other tasks, such as: B. long-term operation in polar waters under ice, tracking coastal shipping in anti-terrorism operations, or sending special forces to foreign shores. Modern diesel-electric submarines, with or without AIP capabilities, are therefore affordable weapons platforms for many navies around the world that want to defend their coastal areas against any potential adversary (including nuclear-armed states).

Ciena introduces intelligent analytics service
New pall service provides Ciena networks providers and large enterprises with practicable intelligence to produce more flexible and adaptive networks
As networks come more complex, with further and further connected bias, druggies and operations, new analytics capabilities enable network providers to turn network performance data into practicable perceptivity. Network providers can now also address this complexity by using Ciena perceptivity Service, the new comprehensive and pall- driven analytics- as-a-service service from Ciena( NYSE CIEN).
The Ciena perceptivity Service is powered by a platoon of largely educated cooperative experts in data, services and network structure, along with artificial intelligence and software machine literacy capabilities. Ciena perceptivity Service helps network providers make better opinions, optimize network asset application, reduce time to vend and induce new profit openings.
Crucial Data
• Ciena perceptivity Service brings together a wide range of analytics functionality into onemulti-tiered service, enabling networks to operate with' secure inflexibility' – now and in the future. The service is offered in a subscription format with three situations of service to choose from, with multiple benefits for Ciena guests
Discover Provides network operation labor force with lesser visibility into network means, vacuity, network health and threat areas.
Analytics Uses machine literacy functionality to reuse trend information into practicable perceptivity to optimize the network.
prognosticate Helps network directors to help problems before they be. This prevents expensive network dislocations and client loss. Preventively, it can be determined where the network can best be optimized and converted for, among other effects, better vacuity of the network, advanced client satisfaction and lower functional costs.
• Ciena perceptivity Service builds on Ciena's expansive portfolio of consulting services and network results, designed to help service providers with moment's complex and changeable network requirements. Ciena perceptivity Service can be stationed on both Ciena packet- optic networks and networks with third- party outfit.

• As a pall- driven analytics- as-a-service immolation, it complements Ciena's Blue Planet ® Analytics( BPA) which is stationed as on- demesne software to enable unrestricted- circlemulti-domain robotization.
