Abstract: A geometry model is defined of a part targeted for a manufacturing operation that includes an additive process followed by a subtractive process. Potential build orientations of the geometry model used in the additive processes are defined, as are one or more removal tools of the subtractive process. For each of the potential build orientations, supports that are used by the additive process at the orientation are determined. One of the build orientations is selected that minimizes portions of one of the supports that are inaccessible via at least one of the removal tools.
Abstract: Embodiments described herein provide a system for facilitating efficient dataset management. During operation, the system obtains a first dataset comprising a plurality of elements. The system then determines a set of categories for a respective element of the plurality of elements by applying a plurality of AI models to the first dataset. A respective category can correspond to an AI model. Subsequently, the system selects a set of sample elements associated with a respective category of a respective AI model and determines a second dataset based on the selected sample elements.

Abstract: A digitally controlled LED illuminator sheet that produces far-field illumination patterns or light field distributions that increase light utilization and application efficiency. A dynamic directional LEDs (or other kinds of solid-state light sources) sheet is positioned under each lenslet of a microlens array. Individual LED beam pointing direction depends on off-axis position relative to optical axis of lenslet. Individual beams from independent LEDs form illumination pixels at the illumination plane or within a volume space and can be modulated in intensity. Illumination pixels partially overlap in far-field illumination plane and illumination volume. Over a large illumination space many illumination pixels will partially superimposed on neighboring illumination pixels, with the overlap being in increments smaller than the size of a pixel.

Abstract: Methods and systems (e.g., for generating selecting a model-order reduction (MOR) technique and/or level of granularity for a MOR that provide at least one of: (a) flexible cost-accuracy tradeoffs, (b) a priori error bounds, and (c) a priori preservation of properties that provide physical fidelity) may include: providing governing equations for a physical system; defining quantities of interest (QoI) for the physical system; semi-discretizing the governing equations to obtain a full-order model (FOM) using a state-space representation; applying a MOR technique to the FOM to obtain a family of ROMs with different cost and accuracy tradeoffs, wherein each ROM approximates the FOM with respect to the QoI; and selecting one or more preferred ROMs from the family of ROMs based, at least in part, on the cost and accuracy tradeoffs.

Abstract: Methods and systems for modeling physical systems may use a hybrid approach for surrogate modeling that incorporates both modeling based on physical principles and fitting to data. For example, a method for developing a reduced-order models (ROM) of a physical system may comprise: defining a quantity of interest (QoI) for the physical system; defining a lumped-parameter surrogate (LPS) of the physical system based on physical principles; deriving a topology from the LPS; deriving a governing equation of the ROM from the topology, wherein the governing equation has unknown parameters; collecting data about the QoI of the physical system; and fitting the governing equation based on the data to derive values for the unknown parameters and yield the ROM, wherein the ROM approximates the QoI.

Abstract: A monitoring system includes an array of optical sensors disposed within a transformer tank. Each optical sensor is configured to have an optical output that changes in response to a temperature within the transformer tank. An analyzer is coupled to the array of optical sensors. The analyzer is configured to determine a sensed temperature distribution based on the sensed temperature. The sensed temperature distribution is compared to an expected distribution. Exterior contamination of the transformer tank is detected based on the comparison.

Abstract: A system and method for translating a 3D image into a 2D image is provided. A 3D image of voxels and properties associated with the voxels is analyzed. Each of the voxels in the 3D image is scaled to match a size of an output tile for a 2D image. Colors are added to the 2D image based on the properties of the voxels. Contour lines are added to the 2D image based on changes in altitude represented by the 3D image. The 2D image is output.

Abstract: Embodiments of the present invention provide a system for querying a graph based on applying filters to a visual representation of the graph. The system allows complicated graph query operations to be performed with ease visually. During operation, the system obtains data indicating vertices and edges of a graph. The system displays a visual representation of the graph for a user. The system receives, from the user, a command defining a local graph filter comprising a region in the visual representation. The system then filters a representation of the graph, and stores the filtered representation.

Abstract: A system is provided for generating a custom article to fit a target surface. During operation, the system compares an input dataset with a number of cut template cut meshes. A respective cut template cut mesh includes one or more cutting paths that correspond to a boundary of the mesh. Next, the system identifies a template cut mesh that produces a closest match with the input dataset, and applies global geometric transformations to the identified template cut mesh to warp the template cut mesh to conform to the input dataset. The system further refines and projects a set of boundary and landmark points from the template cut mesh to the input dataset to define cutting paths for the input dataset. Next, the system applies cutting paths to the input dataset to produce a cut-and-trimmed mesh.

Abstract: One embodiment of the present disclosure provides a system and method for facilitating a search for a hybrid-manufacturing process plan for manufacturing an object. During operation, the system can obtain a set of partial order constraints constraining the order in which a set of at least two manufacturing actions, corresponding to addition or removal of predefined regions of space, appear in a process plan. The system can constrain, based on the set of partial order constraints, a search space. The search space can correspond to a tree in which the nodes represent the object's state and the edges represent available actions at each node. The system can then determine a set of optimized process plans represented by orderings of the actions, corresponding to paths on the search tree, that produce the desired final state in a cost-effective manner.
