Abstract: Disclosed herein are system, method, and computer program product embodiments for the programmatic buying and selling television advertisement. An embodiment operates by receiving a request for an available advertising segment inventory meeting one or more criteria. The system transmits to a buyer system available advertising segment inventory meeting the criteria, and receives an offer for the advertising segment including an offer price and a desired date range. The system then performs a comparative analysis of the order with one or more additional received offers for the advertising segment and transmits an offer acceptance notification based on the analysis.

Abstract: High-efficiency method and device, to produce coherent Smith-Purcell radiation. A conductive diffraction grating, delimited by two conductive walls, is used, and an electron beam is passed above the grating to generate the radiation. According to the invention, the speed of the electrons is sufficiently low in order that, in a diagram (wave number k, frequency f), the beam line (I) intersects a portion (V) of a branch of the dispersion relationship, located in the first Brillouin zone, and corresponding to the grating's fundamental mode, at a point (P) located outside the zone delimited by the light lines (III, IV), and the current density of the beam is sufficiently high to excite the grating's fundamental mode which is radiated towards the outside thereof.

Abstract: A dual mode gas turbine engine includes a dual mode fan and low pressure compressor section upstream of radially inner and outer gas generators which include radially inner and outer combustors disposed in radially inner and outer working fluid flowpaths, respectively, in fluid flow communication with the dual mode fan and low pressure compressor section. An outer low pressure turbine downstream of the outer combustor is drivingly connected to the fan and low pressure compressor section. A common exhaust duct downstream of the inner and outer gas generators is in fluid flow communication with the flowpaths. The outer low pressure turbine may include outer low pressure turbine blades mounted on a rotatable turbine shroud connected to a low pressure rotor which includes the fan and low pressure compressor section. Inner low pressure turbine blades on the low pressure rotor and downstream of a diffusing duct extend across the inner working fluid flowpath and connect the turbine shroud to the low pressure rotor.

Abstract: A nail plate pressing machine for use in manufacturing timber trusses and adapted to travel in a horizontal plane to a selected position, including: locating means for locating two or more truss members to be connected in respective predetermined design positions; a press head adapted for movement from a pre-pressing position in which one or more nail plates may be loaded for pressing to a range of pressing positions in which the one or more loaded nail plates may be pressed into engagement with the two or more adjacent truss members in a predetermined securing position and vice versa, and securing means on said press head adapted to secure any one of a plurality of magazines within a range of magazine sizes, each magazine being adapted to hold a plurality of nail plates or a plurality of nail plate cartridges of a predetermined size respectively for loading, said securing means being adapted to secure each sized magazine in a position in which a selected edge of a nail plate or a nail plate cartridge to be l
