Abstract: A mechanism is provided in a data processing system for minimizing uncertainty envelopes in trajectories of evolving ensemble members. The mechanism generates a trajectory forecast of each member object of an ensemble based on an initial state-space and a model for predicting trajectories of the member objects to generate a plurality of trajectory forecasts. Each of the plurality of trajectory forecasts has an individual uncertainty envelope. The mechanism applies a classification algorithm on the plurality of trajectory forecasts to identify at least one group of member objects having similar trajectory forecasts, generates a reduced ensemble of member objects including the identified group of member objects, and reconfigures the state-space and the model for predicting trajectories. The mechanism generates an updated trajectory forecast of each member object of the reduced ensemble based on the reconfigured state-space and the reconfigured model for predicting trajectories of the member objects.

Abstract: System and method for predicting the mud weight window in formations, particularly those formations having geologic structures such as salt domes. One embodiment is a computer-implemented method of modeling a formation in 3-D and determining a plurality of effective stress ratios for the modeled 3-D formation using finite element analysis. Thereafter, the trajectory of a proposed wellbore through the 3-D modeled formation is plotted and the specific effective stress ratios along the wellbore are selected to form a data set. The 3-D data set of effective stress ratios is then imported into 1-D modeling software and combined with 1-D data. The combined data is thereafter utilized to estimate the mud weight window for the formation around the wellbore.
Abstract: Methods for providing sketch dimensions for a drawing view and corresponding systems and computer-readable mediums. A method includes receiving a geometric model including a revolved feature generated using a sketch having sketch dimensions. The sketch and the sketch dimensions are in a sketch plane. The method includes, in response to one or more sketch objects being visible in a current view plane of the revolved feature, generating a drawing view of the one or more sketch objects in the current view plane. The drawing view includes the sketch dimensions of the one or more sketch objects.

Abstract: Apparatuses, systems, methods, and computer program products are presented for electronically emulating the impedance characteristics of materials, e.g., for standardizing and calibrating electromagnetic measuring devices for the measurement of physical properties of materials. The electronic impedance emulation apparatus according to some embodiments includes an electronic material emulation circuit in communication with the electromagnetic measuring device. The electronic material emulation circuit and the electromagnetic measuring device are controlled by a at least one computing device, which can control the frequency of signal(s) generated by the electromagnetic measuring device. The at least one computing device can instruct the electronic emulator to produce signals having complex impedance characteristics of the material under test at the test frequency. The emulation data can be stored and used for the calibration and/or standardization of the electromagnetic measuring device.
Abstract: A novel and useful method of visualization by detection of EM radiation being irradiated or reflected from objects in the imager's field of view using Finite Element Method (FEM) simulation software tools. The methodology provides a verification method of antenna operation from an electrical point of view since bolometer performance cannot be estimated using regular antenna parameters such as directivity, gain, impedance matching, etc. as the bolometer does not behave as an antenna but rather behaves as an absorber. An incident wave is triggered on the absorber and the absorption of the bolometer structure is estimated using commercially available Finite Element Method (FEM) software (e.g., ANSYS® HFSS software, CST MICROWAVE STUDIO®, etc.). How much of the energy is reflected is subsequently measured. The energy which is not reflected is considered to be absorbed by the absorber.
