The method comprising applying an X-ray field to the cable, detecting the X-ray field intensity that passes through the cable, obtaining a digitized output waveform of the X-ray field intensity as a function of cable position, and determining a trough location of the waveform by averaging calculated position values for the center of the conductor at several longitudinal positions along a cross section of the conductor.

Abstract: The invention is a method of determining all the components of an absolute permeability tensor of a porous medium sample from permeability measurements, obtained for example by placing the sample in a permeameter which is useful for fast determination of permeability anisotropies of rocks and detention of internal heterogeneities. A pressure difference ?P is applied between the inlet and outlet faces of a laboratory rock sample, with zero flow conditions on the edges parallel to the mean flow obtained by confining it in a sheath under pressure. Starting from conventional permeability measurements in three directions and from the measurements of the two components of the viscous forces transverse to the sample, a permeability tensor k can be “inverted” by numerical solution of the corresponding boundary-value problem.

Abstract: It is possible to significantly reduce a prediction error of the high-speed RFV and the high-speed TFV in a tire having a large PRO growth amount at high speed. Three or more sample tires are extracted from each lot. The PRO and RFV are measured and the least-square method is used to predict (100) the upper and lower and front and back natural angle frequency, attenuation ratio, upper and lower spring constant, and rolling radius coefficient. By using the PRO measurement apparatus, the PRO during idling is measured. By using an AAV measurement apparatus, an actual measurement value AAVL of the angle acceleration fluctuation at a low speed is measured (102). The PRO and AAV at a high speed are predicted (104) and the actual measurement value and prediction value are used to predict the high-speed RFV and TFV.

Abstract: Disclosed are a method and system for calibrating grid parameters for a photolithographic tool. One embodiment of the invention utilizes at least two artifacts located on the wafer stage. The artifacts are located outside of the area where a substrate would be placed. Typically, four artifacts are used, with two artifacts located along the same axis. The stage moves a first artifact to the alignment system and the system measures the location of the first artifact. The stage then moves the second artifact, which is on the same axis but on the other side of the wafer stage, under the alignment system and measures the location of the second artifact. This is repeated for the other two artifacts that line up in a second axis (i.e., perpendicular to the first axis). Grid offsets are calculated to provide, for example, grid magnification and rotation calibrations.

Abstract: A control unit receives a sensor output and performs signal processing on the sensor output to produce an internal signal. The control unit produces internal data by adding time data to an internal signal and transmits the internal data to an in-vehicle network. A diagnostic unit receives the internal data from the in-vehicle network and stores the internal data in an internal data storing device. The diagnostic unit also receives a measurement signal produced based on the sensor output. The diagnostic unit produces external data by adding time data containing time at which the second timer resets a time count when an ignition switch is closed and stores the external data. The diagnostic unit reproduces the internal data and the external data and extracts the internal signal and the measurement signal. The diagnostic unit displays or stores the internal signal and the measurement signal according to the time data.

Abstract: A system is provided for obtaining parameters about the position and orientation of a camera, where the camera has a fixed position and orientation, by using the image coordinates and world coordinates of markers included in an image photographed by the camera.

The markers can be extracted by using the image obtained in either mode. The system can select either automatic-extraction mode or manual-extraction mode for extracting the marker in live images, so that the markers can be extracted with a high degree of accuracy under all conditions to obtain the position and orientation parameters of the camera.

Abstract: The present invention is directed to a system and method for monitoring the performance of a heat exchanger. In accordance with the system and method, baseline values of a performance factor (E) for baseline sets of heat exchanger operating values are calculated and stored. A current value of E is calculated for a current set of the operating values and is compared to a retrieved baseline value of E for a baseline set of the operating values that at least substantially matches the current set of the operating values. E provides a measure of the performance of the heat exchanger and is calculated using differential temperatures across the heat exchanger and without using any information concerning the physical construction of the heat exchanger.

Abstract: Combining of reference measurement collections (RMCs) of at least three reference measurement systems into a weighted reference measurement collection (wRMC) is disclosed. Each RMC includes a plurality of corresponding sample measurements, each of which has a measurement value of the same sample. The invention plots corresponding measurement values to generate a plurality of data pairs for each possible RMC pairing. A best-fit line of the plurality of data pairs for each RMC pairing is then generated, and a residual for each data pair is calculated. A weight is then assigned to each sample measurement for each RMC based on the residuals associated with a respective RMC to which the sample measurement belongs, favoring a smaller residual more than a larger residual. A weighted reference measurement is then generated based on the weights, and the measurement value for the respective sample measurement for each RMC.
