Commercial Orbital Transportation Services
Commercial Orbital Transportation Services (COTS) was a NASA program to spur the development of Private spaceflight, private spacecraft and launch vehicles for deliveries to the International Space Station (ISS). Launched in 2006, COTS successfully concluded in 2013 after completing all demonstration flights. NASA's final report on the program considered it a success and a model for future public-private collaboration. Compared to traditional cost-plus contracts employed by NASA, such as the $12 billion contract for the Orion (spacecraft), Orion spacecraft, the $800 million COTS investment resulted in "two new U.S. Medium-lift launch vehicle, medium-class launch vehicles and two automated cargo spacecraft". After the conclusion of the COTS program, NASA shifted towards Fixed-price contract, fixed-price contracts for crew and cargo services. While the approach has significantly lowered costs for NASA, companies other than SpaceX have struggled under the fixed-price system, with som ...

Commercial Off-the-shelf
Commercial-off-the-shelf or commercially available off-the-shelf (COTS) products are packaged or canned (ready-made) hardware or software, which are adapted aftermarket to the needs of the purchasing organization, rather than the commissioning of custom-made, or bespoke, solutions. A related term, Mil-COTS, refers to COTS products for use by the U.S. and Canadian militaries. In the context of the Federal government of the United States, U.S. government, the Federal Acquisition Regulation (FAR) has defined "COTS" as a formal term for commercial items, including services, available in the commercial marketplace that can be bought and used under government contract. For example, Microsoft is a COTS software provider. Goods and construction materials may qualify as COTS but bulk cargo does not. Services associated with the commercial items may also qualify as COTS, including installation services, training services, and cloud services. COTS purchases are alternatives to custom softwa ...

Crown-of-thorns Starfish
The crown-of-thorns starfish (frequently abbreviated to COTS), ''Acanthaster planci'', is a large starfish that preys upon hard, or stony, coral polyps (Scleractinia). The crown-of-thorns starfish receives its name from venomous thornlike spines that cover its upper surface, resembling the biblical crown of thorns. It is one of the largest starfish in the world. ''A. planci'' has a very wide Indo-Pacific distribution. It is perhaps most common around Australia, but can occur at tropical and subtropical latitudes from the Red Sea and the East African coast across the Indian Ocean, and across the Pacific Ocean to the west coast of Central America. It occurs where coral reefs or hard coral communities occur in the region. Description The body form of the crown-of-thorns starfish is fundamentally the same as that of a typical starfish, with a central disk and radiating arms. Its special traits, however, include being disc-shaped, multiple-armed, flexible, prehensile, heavily spine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Connection-oriented Communication
In telecommunications and computer networking, connection-oriented communication is a communication protocol where a communication session or a semi-permanent connection is established before any useful data can be transferred. The established connection ensures that data is delivered in the correct order to the upper communication layer. The alternative is called '' connectionless communication'', such as the datagram mode communication used by Internet Protocol (IP) and User Datagram Protocol (UDP), where data may be delivered out of order, since different network packets are routed independently and may be delivered over different paths. Connection-oriented communication may be implemented with a circuit switched connection, or a packet-mode virtual circuit connection. In the latter case, it may use either a transport layer virtual circuit protocol such as the Transmission Control Protocol (TCP) protocol, allowing data to be delivered in order. Although the lower-layer switc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
