The present invention relates to novel high-latency liquid hardeners for hardening of curable polymer resins, especially epoxy resins, and to epoxy resin compositions comprising liquid hardeners for the production of fiber composite materials. Any arbitrary attributed roadway trajectory point on the curve passes a predetermined proximity test for proximity to point cloud points discriminated as representing part of the along-roadway physical feature. Additionally, congestion is reduced in an upstream ingress port of the packet switch that receives completion packets in response to non-posted packets output from the upstream egress port and provides the completion packets to the downstream egress port. A second mobile communication terminal that cannot execute interference rejection combining offsets the reception quality value of radio waves from the second radio base station by using a second bias value that is lower than the first bias value. Another method increases the flux density by reducing a cross-sectional area of a portion of the current line, wherein the portion of the current line is adjacent to the to the magnetic memory cell structure. The system includes an output device for presenting a media data stream, a communication port for linking to the output device, and a controller coupled to the port.
