Disclosed is an improvement to the bag computer of application Ser. For each functional block within the device-containing layer, lateral heat flow is calculated to laterally adjacent functional blocks. Concurrently, at least one second lateral speed of the aircraft is estimated according to at least one second set of parameters, among which at least one parameter is of different nature from each parameter of the first set of parameters. In other embodiment the bevel angle promotion layer is integrated with a leading edge taper material, which is formed of a magnetic material, to broaden the magnetic flux path between the yoke and the main pole. Compounds prepared by the processes of the invention have demonstrated activity as histamine-3 receptor ligands. The frameless grafting prostheses include a stiffening member useful in the attachment of the frameless grafting prostheses to a wall of a body lumen.
