Abstract: Calibrating Friction Factors. At least some of the illustrative embodiments are methods including: calibrating friction factor for a drilling operation by: plotting on a display device the expected hook load versus depth for the drilling operation; displaying plot points on the display device, each plot point indicative of a measured hook load versus depth for the drilling operation; selecting a plot point associated with a depth, the selecting responsive to a cursor hovering over the plot point on the display device; displaying a friction factor values which correlates the expected hook load versus depth for the particular depth to the measured hook load versus depth for the plot point, selecting the value responsive to the cursor hovering over the value; and then shifting on the display device at least a portion of the indication of expected hook load versus depth based on the value of friction factor.

Abstract: An illustrative scenario compiling method that includes providing a visual representation of a well having well components mapped to different areas of the visual representation, responding to a selection of one of the well components with a list of data sets corresponding to the well component, retrieving a selected data set from a corresponding database, storing the data set in a common location with selected data sets of other well components, and saving the selected data sets as a scenario to be used for assembling a future collection of data sets as input for analysis software.

Abstract: Methods and devices useful in high-speed scalable switching systems include a memoryless switch fabric, per virtual channel queuing, digital phase aligners, randomized and complement connection modes, a mid-point negative acknowledge and output negative acknowledge scheme among other elements. A particular implementation of a routing table and switch element is described in part to illustrate the various techniques and devices of the invention.

Abstract: In a CT imaging system which includes a gantry having a rotatable ring member and a DAS comprising circuit boards grouped in a selected number of sets, a DAS housing is provided which is disposed to dissipate heat away from the DAS circuit boards. The housing includes a frame for mounting each of the circuit boards on the gantry ring so that the boards of a set are in spaced-apart relationship with each other, and further includes a cover for each frame, to form an enclosure for the circuit boards supported thereby. Each cover is provided with a panel member, a section of each panel being provided with a specified pattern of perforations. Each panel is positioned with respect to its set of circuit boards to provide an unobstructed space of selected dimension between its pattern of perforations and its corresponding circuit board set.
