Vancouver's Celebration of Light is the largest firework competition on the planet, attracting around 1.six million spectators annually. In 2009, Canada, South Africa, the UK and China do battle during four nights of amazing displays over English Bay. Each country presents a complete display, with dates as follows; Canada on 22 July, South Africa on 25 July, the UK on 29 July and China on 1 August. Each show lasts about 25 minutes and local firefighters raise funds to the continuing festival along with the Vancouver Fire Fighters Charitable Society.
14. In order to ensure the train operation safety and order, as far as possible not to stop delivery scheduling command, scheduling command wireless transmission system, the system should be used to value multiplied driver release scheduling command, is involved in running conductor, by the driver to operate the commander to convey; When the content and conditions of dispatching and dispatching orders are issued and conveyed by using the wireless dispatching communication equipment, the dispatch and dispatch order of the wireless dispatching communication equipment shall be applied. In the absence of the above conditions, there is a suspension station in this section, and the train dispatcher delivers the dispatch order at the stop station before entering the relationship interval; There is no stop in this section. The bureau may entrust the station with the station to forward the dispatching order to the operator and the operator. The entrusted office shall indicate to the entrusted authority the contents and specific vehicles of the dispatch and dispatching order, and the entrusted office shall not refuse the commission when the time permits. If the train is not in time, it must stop at the station before the train enters the relationship. The entrusted telephone shall have a good communication recording device.
The first known patent with an electric mixer, according to the book ?Antique Electric Mixers? by Dennis Thompson, was handed to Rufus W. Eastman in 1885. It was a peculiar machine developed to operate on electricity or water power. Herbert Johnston, an engineer around 1908 saw a baker blend bread dough with only an iron spoon. As a result, Johnston was inspired to produce the most popular standing mixer. Eighty quart commercial grade mixers went on the market and instantly were thought of as a large labor saving tool around 1914. Trying out a home model, the wife of an executive proclaimed that it is ?the most effective kitchen aid I?ve ever endured? and therefore a brandname name is made. Since then, the standard home based mixers may be called KitchenAid. Validating KitchenAid?s advertisement which stated that it is mixer with attachments could ?do everything!?, today?s attachments have the capability to make pasta, fill up sausage, crush food, squeeze citrus, in addition to creating frozen goodies.
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
