Each streamlined body extends in a first transverse direction into the gas-flow channel, and has two lateral surfaces that are arranged essentially parallel to the main-flow direction. The lateral surfaces are joined to one another at their upstream and downstream sides to form leading and trailing edges of the body, respectively. At least one of the streamlined bodies includes a mixing structure and at least one fuel nozzle at its trailing edge for introducing at least one fuel essentially parallel to the main-flow direction into the flow channel. At least two of the streamlined bodies have different lengths along the first transverse direction such that they may be used for a can combustor.

Abstract: Techniques for facilitating transactions are described in which the system facilitating the transaction engages in natural language dialog with the user to achieve the desired result. Instead of treating successive input independently, the system maintains a dialog context in which information generated in response to recent input may be used to inform responses to further input.

Abstract: A knockdown bed is formed of a first bed frame and a second bed frame. The first bed frame includes a top side, a bottom side, and an insertion member. The insertion member has an insertion end, a fixed end connected with the bottom side, two lateral sides, and two abutment surfaces connected with the two lateral sides. The two abutment surfaces gradually approach each other from the fixed end to the insertion end. The second bed frame includes a top side, a bottom side, and a slot member adjacent to the first bed frame. The slot member is formed of two sidewalls, two abutment walls connected with the two sidewalls, and a slot, into which the insertion member can be inserted to interconnect the first and second bed frames. In this way, the knockdown bed can be easily assembled and structurally firm.
