Abstract: A communications system includes a source, a destination, and multiple relays. In a first time period, the source emits a first transmission and a first relay retransmits a prior source transmission. Then, in a second, subsequent time period, the source node emits a second transmission and a second relay transmits the source transmission from the first time period. Optionally, the transmission from the second relay also includes the message from the first relay during the first time period. Similarly, in a third time period, the first relay transmits a message that includes the second relay's transmission and the second source transmission from the second time period. Alternatively, the source node transmit in a first frequency band, the first and second relays receive only in the first frequency band, and retransmit in a second frequency band, and the destination receives in both the first and second frequency bands.

Abstract: A system and method for increasing the efficiency and/or power produced by an integrated gasification combined cycle system by increasing the integration between the air separation unit island, the heat recovery steam generator and the remainder of the system. By integrating heat produced by the heat recovery steam generator in the remainder of the integrated gasification combined cycle system, heat may be utilized that may have otherwise been lost or used further downstream in the system. The integration helps to increase the efficiency of the combustion reaction and/or the gasification reaction used to produce the syngas utilized in the integrated gasification combined cycle system.

Abstract: A diffuser for decelerating a compressed gas, is provided, which includes a ring divided at circumferential positions around the ring into several arcuate sections, the complete ring is assembled from these sections. The ring defines one or more passages, the cross-section of which increases in the direction of flow of a fluid through the diffuser.

The interface is configured to have a series of interlocking serrations along the axial length of the diffuser. In an embodiment, there are two arcuate sections involving two interfaces, and the peaks and troughs of the serrations of each of the two sections are arranged at an angle to a longitudinal axis of the diffuser. A small relative movement between the sections is achieved when the two angles at the two interfaces have opposite signs.

Abstract: A method is disclosed for homogenization of threshold values of a multichannel, quanta-counting radiation detector. In an embodiment of the method empty measurements are carried out with the detector at different spectral compositions of the radiation with different settings of threshold values of the comparators. For each channel of which the comparators is to be set to the same energy threshold, an adapted threshold value is determined for this energy threshold from the empty measurement, at which a variation of the normalized count rate of the channel is minimized over the different spectral compositions of the radiation. This avoids problems in the further processing of the measurement data of the detector, which can occur during alterations of the spectrum.

Abstract: A railway vital or critical application system substitutes commercial off-the-shelf (COTS) hardware and/or software for railway-domain specific product components, yet is validated to conform with railway vital system failure-free standards. The vital system uses a pair of COTS personal computers and operating systems with asymmetric communications capability. Each computer and operating system may differ for additional redundancy. Both computers receive and verify vital systems input message data and security code integrity and separately generate output data responsive to the input message. The first computer has sole capability to send vital system output messages including the output data and an output security code, but only the second computer has the capability of generating the output security code. A failure of either computer's hardware, software or processing capability results failure to transmit a vital system output message or an output message that cannot be verified by other vital systems.
