Abstract: Hydrogen-producing fuel processing systems and related methods. The systems include a hydrogen-producing region configured to produce a mixed gas stream from a feedstock stream, a hydrogen-separation membrane module having at least one hydrogen-selective membrane and configured to separate the mixed gas stream into a product hydrogen stream and a byproduct stream, and an oxidant delivery system configured to deliver an oxidant-containing stream to the hydrogen-separation membrane module in situ to increase hydrogen permeance of the hydrogen-selective membrane.

Abstract: A method includes evaluating a transaction using a first swarm member to generate a first cooperative prediction related to the transaction. The first cooperative prediction is based, at least in part, on a first affinity value of the first swarm member to one or more other swarm members. The method also includes evaluating the transaction using a second swarm member to arrive at a second cooperative prediction related to the transaction. The second cooperative prediction is based, at least in part, on a second affinity of the second swarm member to one or more other swarm members. A swarm prediction related to the transaction is generated based on both the first cooperative prediction and the second cooperative prediction.

Abstract: Techniques and systems suitable for performing low-loss fusion splicing of optical waveguide sections are provided. According to some embodiments, multiple laser beams (from one or more laser) may be utilized to uniformly heat a splice region including portions of the optical waveguide sections to be spliced, which may have different cross-sectional dimensions. According to some embodiments, the relative distance of the optical waveguide sections and/or the power of the multiple laser beams may be varied during splicing operations.

Abstract: To secure an accessible computer system, the computer system is monitored for connection transactions. An access requestor is denied access to the computer system when the access requestor initiates a number of connection transactions that exceed a configurable threshold number during a first configurable period of time. The monitoring may include detecting connection transactions initiated by the access requestor, counting the number of connection transactions initiated by the access requestor during the first configurable period of time, and comparing the number of connection transactions initiated by the access requestor during the first configurable period of time to the configurable threshold number.

Abstract: To secure an access provider, communications to/from the access provider are monitored for a partially-completed connection transaction. Detected partially-completed connection transactions are terminated when they remain in existence for a period of time that exceeds a threshold period of time. The monitoring may include detecting partially-completed connection transactions initiated by an access requestor, measuring the period of time that a partially-completed connection transaction remains in existence, comparing the period of time with the threshold period of time, and resetting a communication port located on the access provider.

Abstract: Securing an accessible computer system typically includes receiving a data packet that includes a payload portion and an attribute portion, where the data packet is communicated between at least one access requestor and at least one access provider. At least the payload portion of the received data packet typically is monitored, where monitoring includes scanning the payload portion for at least one predetermined pattern. When the payload portion is determined to include at least one predetermined pattern, access by the access requestor to the access provider may be controlled. Monitoring the data packet may include scanning the payload portion while handling the data packet with a switch. Controlling access may include denying access by the access requestor to the access provider.

Abstract: Fuel cell stacks and systems with thermal management systems to deliver a liquid heat exchange fluid into thermal communication with the stack and thereafter recycle the stream. In some embodiments, the system is adapted to selectively apportion the recycled liquid stream between a stream that, prior to reuse as a heat exchange stream, is returned to a fluid reservoir and/or selectively cooled, and/or selectively returned to the reservoir and mixed with heat exchange fluid in the reservoir, and a stream that is returned into thermal communication with the stack without returning the stream to the reservoir and/or without heating or cooling and/or without being mixed with additional heat exchange fluid. In some embodiments, the system is adapted to automatically apportion the recycled stream responsive to its temperature. In some embodiments, the system includes a thermostatic valve and/or selectively apportions the recycled stream without requiring an electronic controller or manual input.
