摘要： Methods to in-situ monitor production of additive manufacturing products collects images from the deposition process on a layer-by-layer basis, including a void image of the pattern left in a slurry layer after deposition of a layer and a displacement image formed by immersing the just-deposited layer in a renewed slurry layer. Image properties of the void image and displacement image are corrected and then compared to a binary expected image from a computer generated model to identify defects in the just-deposited layer on a layer-by-layer basis. Additional methods use the output from the comparison to form a 3D model corresponding to at least a portion of the additive manufacturing product. Components to control the additive manufacturing operation based on digital model data and to in-situ monitor successive layers for manufacturing defects can be embodied in a computer system or computer-aided machine, such as a computer controlled additive manufacturing machine.

摘要： A method designs nuclear reactors using design variables and metric variables. A user specifies ranges for the design variables and threshold values for the metric variables and selects design parameter samples. For each sample, the method runs three processes, which compute metric variables for thermal-hydraulics, neutronics, and stress. The method applies a cost function to compute an aggregate residual of the metric variables compared to the threshold values. The method deploys optimization methods, either training a machine learning model using the samples and computed aggregate residuals, or using genetic algorithms, simulated annealing, or differential evolution. When using Bayesian optimization, the method shrinks the range for each design variable according to correlation between the respective design variable and estimated residuals using the machine learning model. These steps are repeated until a sample having a smallest residual is unchanged for multiple iterations. The final model assesses relative importance of each design variable.

摘要： Pre-ceramic particle solutions can prepared by a Coordinated-PDC process, a Direct-PDC process or a Coordinated-Direct-PDC process. The pre-ceramic particle solution includes a polymer selected from the group consisting of (i) an organic polymer including a metal or metalloid cation, (ii) a first organometallic polymer and (iii) a second organometallic polymer including a metal or metalloid cation different from a metal in the second organometallic polymer, a plurality of particles selected from the group consisting of (a) a ceramic fuel particle and (b) a moderator particle, a dispersant, and a polymerization initiator. The pre-ceramic particle solution can be supplied to an additive manufacturing process, such as digital light projection, and made into a structure (which is pre-ceramic particle green body) that can then be debinded to form a polymer-derived ceramic sintered body. In some embodiments, the polymer-derived ceramic sintered body is a component or structure for fission reactors.

摘要： An absorbent article, such as a sanitary napkin, includes a top sheet and a back sheet with a resilient, composite absorbent core sandwiched therebetween. To decrease the stiffness, the absorbent core includes an outer line and an inner line on each side of a longitudinal centerline. The outer line includes a plurality of slits having spaces therebetween, and the outer line extends convexly when viewed from the longitudinal centerline. The plurality of slits in the absorbent core impart better bending ability of the absorbent article, particular for stiff airlaid absorbent cores.

摘要： A method (20) for determining a maintenance interval for a consumable part and/or for equipment containing a consumable part obtains a plurality of measurements of temperature of the consumable part (22), receives each of the measurements at a totalizing unit (24), correlates each of the measurements to one of a plurality of temperature subranges (26), accumulates for each of the subranges an amount of time the measurements of temperature were correlated to each of the subranges (28), determines a total time by aggregating the accumulated time for each subrange with a weighting function (30), and generates a signal to prompt a maintenance event when the total time equals or passes a runtime setpoint (32). In supplement to or in alternative to the above, the method also correlates a subrange of two sequential measurements (34), indexes a breakpoint register if the correlated subranges are different (36), and generates a signal to prompt a maintenance event when a value of the breakpoint register equals or passes a breakpoint setpoint (32). A system for collecting, storing, and displaying runtime data of a resistive heating element in a semiconductor processing unit is also disclosed.

摘要： An exemplary embodiment of a material removal tool (200, 300) has a housing (202) at a mating end (204), an extension (208) longitudinally extending from the housing (202) to a distal end (210), a plurality of spacers (218) arranged along the extension (208), and a nut (212) at the distal end (210) of the extension (208), wherein the plurality of spacers (218) are formed from a material having a Young's modulus of greater than about 1.5 times that of steel. The spacers (218) along the extension (208) of the tool (200) place the stiffer material of the spacer at a location of greatest resistance to bending moments (i.e. highest sectional modulus). Optionally preloading and "built-in" relief points contribute to improved performance of the material removal tool (200, 300). A method of manufacturing a material removal tool (200, 300) and a method of machining a workpiece are also disclosed.

摘要： Additive manufacturing compositions include low-absorbing particles or non-absorbing particles that have an absorbance for wavelengths of 300 nm to 700 nm that is equal to or greater than 0 Au and is less 1.0 Au, such as 0.001 Au ≤ absorbance ≤ 0.7 Au. Slurries including such particles and an uranium-containing particle and that are used in additive manufacturing processes have an increased penetration depth for curative radiation. Removal of low-absorbing particles or non-absorbing particles during post-processing of as-manufactured products results in pores that create porosity in the as-manufactured product that provide a volume accommodating fission gases and/or can enhance wicking of certain heat pipe coolant liquids. Low-absorbing particles or non-absorbing particles can be functionalized for improved properties, for example, with fissionable material for improved ceramic yields, with burnable poisons or stabilizers for increased homogeneity, with stabilizers for localized delivery of the stabilizer, or with combinations thereof.
