Abstract: A method and system for identifying short message service (SMS) spammers identifies senders as spammers by determining that the senders are sending SMS messages to devices included in a grey phone space. Devices in the grey phone space are identified using various methods including an analysis of call detail records. A grey ratio for a sender is determined as a ratio of messages sent to grey phone numbers by the sender to messages sent to all phone numbers by the sender. A sender is identified based on a difference between the grey ratio for the sender and a second grey ratio being above a threshold.

Abstract: A neutron generator includes carbon nanotubes that function as the anode and provide deuterium storage. The ionization source includes a layer of carbon nanotubes that provides a pulse of deuterium ions through field-induced desorption and ionization of deuterium atoms on the surface or retained in the bore of the nanotubes. A high-yield (>1010 n/s) neutron generation is achieved by employing a field desorption ion source and applying an electric field of 10-40 V/nm. Such high fields may be achieved with carbon nanotubes having high aspect ratios with field enhancement factors on the order of 1000. By operating the ion source in a background pressure of deuterium or hydrogen, the gas adsorption on the nanotubes may be regenerated after each pulse.

Abstract: A continuous serpentine cooling circuit forming a progression of radial passages (44, 45, 46, 47A, 48A) between pressure and suction side walls (52, 54) in a MID region of a turbine airfoil (24). The circuit progresses first axially, then tangentially, ending in a last radial passage (48A) adjacent to the suction side (54) and not adjacent to the pressure side (52). The passages of the axial progression (44, 45, 46) may be adjacent to both the pressure and suction side walls of the airfoil. The next to last radial passage (47A) may be adjacent to the pressure side wall and not adjacent to the suction side wall. The last two radial passages (47A, 48A) may be longer along the pressure and suction side walls respectively than they are in a width direction, providing increased direct cooling surface area on the interiors of these hot walls.

Abstract: Multi-scale turbulation features, including first turbulators (46, 48) on a cooling surface (44), and smaller turbulators (52, 54, 58, 62) on the first turbulators. The first turbulators may be formed between larger turbulators (50). The first turbulators may be alternating ridges (46) and valleys (48). The smaller turbulators may be concave surface features such as dimples (62) and grooves (54), and/or convex surface features such as bumps (58) and smaller ridges (52). An embodiment with convex turbulators (52, 58) in the valleys (48) and concave turbulators (54, 62) on the ridges (46) increases the cooling surface area, reduces boundary layer separation, avoids coolant shadowing and stagnation, and reduces component mass.

Abstract: A dielectric layer is directly applied onto the surface of a heat sink part. For example, the composition for making the dielectric layer may be made into a paste or ink and then printed as a paste or ink, or applied with some other equivalent method, such as a lamination technique. The electrical circuit traces are then printed in a similar fashion onto the dielectric layer in the required pattern for whatever circuitry is to be applied. That circuitry (e.g., circuit elements) is then attached to the electrical traces as needed for the particular application.
