Abstract: A mobile selective catalytic reduction (SCR) system for a gas turbine includes a base trailer and a selective catalytic reduction duct assembly disposed on the base trailer. The selective catalytic reduction duct assembly is configured to be operably coupled with the gas turbine and receive exhaust from the gas turbine. The SCR system also includes a selective catalytic reduction stack configured to be disposed on the base trailer and operably coupled with the selective catalytic reduction duct assembly. The SCR system further includes a self-erecting trailer detachably coupled with the selective catalytic reduction stack and configured to position the selective catalytic reduction stack on the base trailer.

Abstract: Modular bag system having one or more base bags and a plurality of attachable gear sets. In some configurations, a base bag or a gear set includes a pocket flap that easily moves from an external orientation to an internal orientation to permit access to the pocket. In some configurations, a bag has a strap arrangement that converts from a two-strap arrangement to a single-strap arrangement.

Abstract: A system includes a base configured to be positioned on a ground. The base includes a funnel configured to be positioned under a knife gate. The base also includes a first conveyor positioned under the funnel. The funnel is configured to direct a material from the knife gate onto a middle portion of the first conveyor. The system also includes a derrick having a first end that is coupled to the base. The derrick includes a second conveyor configured to receive the material from the first conveyor and to convey the material upward when the system is in an unfolded state. The derrick also includes a drum motor positioned proximate to an end of the derrick and configured to provide power to the second conveyor. The system also includes a first arm having a first end that is coupled to the end of the derrick.

Abstract: A system includes a base configured to be positioned on a ground. The base includes a first conveyor configured to convey a granular material. The system also includes a derrick coupled to the base. The derrick is configured to be oriented substantially horizontally when the system is in a folded state. The derrick is configured to be oriented substantially vertically when the system is in an unfolded state. The derrick includes a second conveyor configured to receive the granular material from the first conveyor and to convey the granular material. The system also includes a first arm coupled to the derrick. The first arm includes a third conveyor configured to receive the granular material from the second conveyor and to convey the granular material.

Abstract: Methods, systems, and computer-readable media are disclosed for packet sanitization. A particular method intercepts a packet of a packet stream, where the packet stream is transmitted in accordance with a particular protocol. The packet is analyzed based on a specification associated with the particular protocol. Based on the analysis, a data value of a field of the packet is replaced with a sanitized data value to create a sanitized packet. The sanitized packet may be injected into the packet stream or may optionally be forwarded to a signature module that checks the sanitized packet for malicious content. When malicious content is found, the sanitized packet may be dropped, the sanitized packet may be logged, the sanitized packet may be redirected, or a notification regarding the sanitized packet may be sent to an administrator.

Abstract: An apparatus (500) for fatigue testing elongate test articles (404) including wind turbine blades through forced or resonant excitation of the base (406) of the test articles (404). The apparatus (500) includes a testing platform or foundation (402). A blade support (410) is provided for retaining or supporting a base (406) of an elongate test article (404), and the blade support (410) is pivotally mounted on the testing platform (402) with at least two degrees of freedom of motion relative to the testing platform (402). An excitation input assembly (540) is interconnected with the blade support (410) and includes first and second actuators (444, 446, 541) that act to concurrently apply forces or loads to the blade support (410). The actuator forces are cyclically applied in first and second transverse directions. The test article (404) responds to shaking of its base (406) by oscillating in two, transverse directions (505, 507).

Abstract: A system (1100) for fatigue testing wind turbine blades (1102) through forced or resonant excitation of the base (1104) of a blade (1102). The system (1100) includes a test stand (1112) and a restoring spring assembly (1120) mounted on the test stand (1112). The restoring spring assembly (1120) includes a primary spring element (1124) that extends outward from the test stand (1112) to a blade mounting plate (1130) configured to receive a base (1104) of blade (1102). During fatigue testing, a supported base (1104) of a blade (1102) may be pivotally mounted to the test stand (1112) via the restoring spring assembly (1120). The system (1100) may include an excitation input assembly (1140) that is interconnected with the blade mounting plate (1130) to selectively apply flapwise, edgewise, and/or pitch excitation forces.

Abstract: A human-readable list of patch differences ranked by weight helps vulnerability analysts allocate their time. From binary code, identified source functions and recognized sink functions are used when assigning relative weights to changes caused by a patch. Source functions are identified using an export table, import table, and remote procedure call interface. Sink functions are recognized using blacklisted functions, patch-targeted functions, memory functions, string functions, and functions called with mismatched parameters. A change prioritizer assigns weights based on an architectural graph and a set of prioritization rules that specify what kind of change is made by a patch, and what kind of function is changed. Weight assignments may be additive. Rules may assign certain kinds of change a higher priority for subsequent scrutiny by an analyst.
