Methods and systems for detecting a closure and/or opening of a navigable element
A method of detecting the closure and/or opening of a navigable element forming part of a network of navigable elements within a geographic area. A passability parameter is associated with each segment of an electronic map representing the navigable network and indicates a likelihood of closure of the element represented by the segment. The value of the passability parameter decays over time. When a device is detected on the element represented by the segment, the passability parameter is increased, and when a closure report is received relating to the segment, the parameter is decreased. In one set of embodiments, when the passability parameter decreases below a first threshold value, the element represented by the segment is determined to be potentially closed. In another set of embodiments, when the passability parameter increases above a second threshold value, the closed element represented by the segment is determined to be opened. |

Uniformity of deposition can be improved by rotating the deposition source through T degrees and back through T±d, with a total of 360/d repetitions. The reactor can be a CVD reactor that deposits polysilicon onto a heated filament. |

Method of manufacturing fuel rail for gasoline direct injection
To obtain, at low cost, a fuel rail that maintains low hardness and good formability before being formed into a tube stock, can be made to form a welded pipe, and has high-strength properties with which the fuel rail can withstand a high fuel pressure even when formed so as to be relatively thin. A fuel rail for gasoline direct injection that is used at a fuel pressure of at least 30 MPa and is formed from an iron-alloy welded pipe. The fuel rail comprises an iron alloy that contains chemical components of C, Si, Mn, P, S, Nb, and Mo. The plate thickness t and the outer diameter D of the fuel rail have a ratio t/D of 0.2 or less. A bainitic structure can be precipitated by brazing the fuel rail in a furnace during manufacturing. |
