Abstract: Disclosed is a system and method for improving oil and gas drilling scheduling. A plurality of project projections is performed by accessing data elements, each associated with criteria. Each of the criteria is used to project expected gas production from gas wells, and the criteria include a number of crews to perform jobs and a total number of jobs. The criteria are converted into a uniform data format. Next, a total number of simulations (M) are executed in parallel up to the total number of jobs or until a time period expires. The simulations include evaluating each of the jobs to be performed and which crews are available to perform jobs and executing an algorithm to produce results, wherein the results include a schedule of crews and jobs and a production timeline. The results are ranked with the highest gas production. The results are sent to a display.

Abstract: A method of designing and manufacturing a replica composite object based on an original object. The method identifies the structure and physical properties of an original object. Base materials, bodies, and structural templates, each of which includes associated physical properties, are utilized to generate a 3-dimensional model. The 3-dimensional model is discretized and tested to determine if the selected combination of base materials and bodies have physical properties that substantially equal the physical properties of the original object. If the physical properties do not equate, the 3-dimensional model is optimized by adjusting the combination of base materials, bodies, and structural templates. When the difference between the measured physical properties of the 3-dimensional model and the identified physical properties of the original object is less than a tolerance value, the method instructs an additive manufacturing system to generate a replica composite object based on the original object.

Abstract: A system and method that relies on the principles of material science, deformable body mechanics, continuum mechanics and additive manufacturing to reduce the costs associated with additive manufacturing.

Abstract: Methods of optimizing additive manufacturing processes for improved efficiencies and accuracies, particularly by simplifying the user interface portions of the processes. The methods use path-finding calculations, such as vector fields, vector trails, and texture maps, to form accurate models from which replica composite objects can be printed, without requiring complex parameter inputs and calculations from the user. The methods measure and plot vector fields by considering the location of a particle within the volume of an object at various points of time to develop a strand-like model that is used to manufacture a replica object.

Abstract: Embodiments relate to multi-focal intravascular pressure catheters and related systems and methods. In an embodiment, a catheter comprises a plurality of pressure sensors spaced apart along at least a portion of the catheter. Each of the plurality of pressure sensors can comprise a pressure membrane arranged over an aperture in the catheter. In an embodiment, the pressure membrane can comprise carbon nanotubes, silver or gold nanoparticles, or another suitable material that can provide a signal in response to a mechanical change (e.g., deformation or flexing of the pressure membrane) to indicate a pressure or change in pressure. Signals from the plurality of pressure sensors can be communicated to an electrical interface which can calibrate or convert the signals into a visual indication of the pressure at any one of the plurality of pressure sensors as well as pressure gradients between various ones of the plurality of pressure sensors.

Abstract: Methods of optimizing additive manufactured three dimensional structures that are designed to output a desired set of optical properties, particularly for use in tactile-based sensing applications. The optical properties within an object are highly-customizable and can be altered on a voxel-by-voxel level, such that the resulting optical properties can be used in applications in which discreet points within the object are interactable in different ways, thereby providing for different sensations depending on the selected discreet point. Moreover, the selected optical properties can differ between adjacent voxels, allowing for precise customization of the object depending on the requirements of the manufactured object. As a result, the resulting three dimensional structures include a precise, desired set of optical properties, providing for intricate interactions by a user in tactile applications.

Abstract: A method of selecting, printing, and removing a support removal structure from an additive manufactured object, such that the support removal structure provides structural support for the object during printing. The inclusion of support removal structure within a printed object prevents the object from collapsing during printing. After the printed object is completed and cured during post-processing, the support removal structure is removed from the object to provide an object including accurate physical properties. The support removal structure is elongated and compliant and is specially designed for an individual printed object to provide optimal support during a printing process without tangling during removal.

Abstract: A stackable, modular additive manufacturing printer filament feed device including various modules, or components, used to track, quantify, feed, and treat filament used in a 3D printer. The device is designed to provide an accurate quantification of the amount of filament remaining in an additive manufacturing printer by tracking the bidirectional linear translation of filament being fed into the additive manufacturing printer. In addition, the device is portable and does not require an input from the printer to operate; instead, the device mechanically couples to the printer, such that filament passes through the device and is fed into the printer during a printing project. The stackable nature of the device allows for customization depending on printing needs—as such, the device can perform multiple functions, in addition to feeding and tracking filament to an additive manufacturing printer.
