Abstract: The invention relates to radiation-treated reinforcement fibers, reinforced asphalt and portland cement concrete, and grout, methods for producing the same and application for their use. The radiation treatment includes exposing reinforcement fibers to electromagnetic energy, e.g., gamma rays, and/or electron-beam (E-beam) radiation. As a result of the treatment, the radiation-treated reinforcement fibers have a modified or deformed surface, e.g., an abraded and/or porous surface, as compared to reinforcement fibers without a radiation treatment.

Abstract: A method and system for a wireless communication system for a moving vehicle having a plurality of carriages is disclosed. The system comprises at least one internal network onboard said vehicle and at least one router, connected to the internal network and to at least one exterior mobile network, wherein the internal network comprises a plurality of network switches, connected together by cables, wherein the network switches are Power over Ethernet (PoE) switches. In at least one of the network switches it is determined if an input power received from a power supply is below a minimum power level. In case it has been determined that the input power level is below the minimum power level, power is received as Power over Ethernet from at least one of the other network switches, and the switch continues at least part of the network switch operation also when powered by the at least one other network switch.

Abstract: Methods and apparatus for implementing high-bandwidth memory subsystems in a multiprocessor computing environment. Each component in the memory subsystem has a recalibration procedure. The computer provides a low-frequency clock signal with a period substantially equal to the duration between recalibration cycles of the components of the memory subsystem. Transitions in the low-frequency clock signal initiate a deterministically-determined delay. Lapse of the delay in turn triggers the recalibration of the components of the memory subsystem, ensuring synchronous recalibration. Synchronizing the recalibration procedures minimizes the unavailability of the memory subsystems, consequently reducing voting errors between CPUs.
