Abstract: A processing system employs a processing tool to process workpieces, for example cold working holes and/or installing expandable members into holes. Sensors sense various aspects of the processing. Information regarding performance of the process and/or materials may be stored, for example a hole-by-hole or a workpiece-by-workpiece basis, allowing validation of processing. Information also allows dynamic operation of the processing tool. Analysis of response relationships (e.g., pressure or force versus position or distance) may provide insights into the process and materials, and/or facilitate the real-time feedback including control, alerts, ordering replacement for consumable components.

Abstract: One or more crack inhibitors can be installed to improve fatigue performance by producing stress states that prevent or inhibit crack initiation. Crack inhibitors can also prevent or retard crack growth. A mandrel can be used to radially expand the crack inhibitors to both induce compressive residual stresses and to form an interference fit between the crack inhibitor and a workpiece. The mandrel can be removed from the installed crack inhibitor, which is left in the workpiece to ensure proper stress states are maintained.

Abstract: A processing tool to process workpieces, for example cold working holes and/or installing expandable members into holes includes an expansion assembly with a plurality of elongated expansion segments. A first band and a second band couple the expansion segments into an array with the expansion segments circumferentially distributed about a longitudinal axis, with a passageway extending between the arrayed segments. The processing tool may include a tuning assembly that allows a radial expansion amount of the expansion assembly to be adjusted without altering a stroke length of a drive member of the processing tool. Sensors may sense various aspects of the processing performed by the processing tool to enable analysis and storage of information regarding performance of the process and/or materials processed by the processing tool.

Abstract: A document analysis tool provides a 3-dimensional network representation of temporal evolution of text in a document. First and second portions of text are extracted from one or more documents. The texts are parsed to identify noun phrases. The noun phrases are stemmed to remove word variations. Words from the first portion of the text are linked together to form a first layer in the network. Words from the second portion of the text are linked together to form a second layer in the network. The second layer exists in a different temporal plane from the first layer. Words that are common between first and second layers are linked together between the first and second layers to provide a visual and analytical representation of relationship between the first and second portions of the text.

Abstract: A network text analysis called center resonance analysis (CRA) is presented which represents texts (or transcribed conversations) as networks of centering words. The networks of centering words are components of utterances or (specifically noun phrases) that authors and/or speakers deploy in a manner that makes their utterances coherent. A CRA network can be derived for any text, and abstractly represents its main concepts, their influence, and their interrelationships.
