Organization:Internet Archive
The Internet Archive discovers and captures web pages through many different web crawls.At any given time several distinct crawls are running, some for months, and some every day or longer.View the web archive through theWayback Machine.
The seed for Wide00014 was:

- Slash pages from every domain on the web:

-- a list of domains using Survey crawl seeds
-- a list of domains using Wide00012 web graph
-- a list of domains using Wide00013 web graph

- Top ranked pages (up to a max of 100) from every linked-to domain using the Wide00012 inter-domain navigational link graph

-- a ranking of all URLs that have more than one incoming inter-domain link (rank was determined by number of incoming links using Wide00012 inter domain links)
-- up to a maximum of 100 most highly ranked URLs per domain 

The seed list contains a total of 431,055,452 URLs
The seed list was further filtered to exclude known porn, and link farm, domains
The modified seed list contains a total of 428M URLs

Pipeline Technology

Much has changed in the design and operations of oil pipelines since the first were built in Canada and the United States during the 1860s. Those early small-diameter pipelines have long since been decommissioned, and modern-day pipelines benefit from some of the most advanced and environmentally-conscious technology available:

Centralized Control Centre

Centralized Control Centre monitors flow rates, pressures and fluid characteristics 24 hours a day, seven days a week. Fluctuations can be quickly detected, alerting operators to potential leaks, and allowing them to shutdown lines and dispatch crews.

Valves

Check valves can only open when upstream pressure exceeds downstream pressure. If the downstream pressure exceeds upstream pressure for any reason, then the valve automatically closes and reverse flow in the pipeline is blocked.

Block Valves are typically automated and can be controlled remotely. They feature an electric actuator that is connected via satellite or other communications system. If a problem is detected and sent to the Control Centre as an alarm, the operator will follow written procedures, which may include stopping the pipeline and closing the Block Valves to isolate the area until the condition can be investigated and resolved.

High-Performance Coating

High-performance coating systems greatly reduce corrosion hazards.

Smart Pigs

Internal inspection tools called Smart Pigs are sent down the pipeline with the product. Carrying onboard computers and sensors, they measure the diameter of the pipe and the thickness of the pipe wall and can detect dents, gouges or other damage to pipeline. Ultrasonic or EMAT (Electro magnetic acoustical transmission) testing further detects signs of any corrosion or cracks that have initiated in the pipe.
