Having worked in the support sell for dedup appliances in the past year or so I've learned that there's a great lack of understanding with regards to Ethernet technologies. A common example of it is a customer who replaces a vintage VTL appliance once you get your "fast" NAS based backup appliance. They read a marketing and advertising document stating that this new NAS dedup appliance can do approximately 650 MB/s, purchase it and connect it for their LAN using multiple 1 GbE ports. They start backups to discover that their performance is well below those of both the or 4 GBs fiber channel VTL that they had just replaced. Eventually they've created an appointment to the vendor complaining concerning the speed.
Spacecraft flew hundreds of thousands to hundreds of millions of kilometers from the earth, injecting speed when the size and direction of a slight error, arrived at target planets will appear large deviation error, for example, when Mars probe injecting speed 1 m/s speed (about one over ten thousand), arrived at Mars, about 100000 km distance deviation. Therefore, precise control and navigation must be carried out during the long flight. Flying to the moon is usually controlled by the orbital control system of the ground and space probe (see orbit control). Interplanetary flight distances, radio signal transmission time is long, the real-time remote control, can't so planets and interplanetary spacecraft orbit control system shall have the ability of autonomous navigation (see interstellar travel navigation and control). The United States, for example, "pirates" spacecraft in space flight of more than eight hundred million km, for 11 months of 2000 times of autonomous orbit adjustment, the final surface to achieve a soft landing on Mars, placement accuracy up to 50 km. In addition, in order to ensure the accuracy of the orbit control engine, the communication antenna is always aimed at the earth, and other systems work normally, and the detector has the autonomous attitude control ability
British Glass is calling for seminar presentations, based on practical examples of large manufacturing businesses securing funding for improvement in energy efficiency and carbon reduction, for a one-day glass industry event in November 2017.
