Abstract: A testing apparatus for obtaining mechanical properties of a polymer composite extruded from a nozzle of a compounding extruder includes a plurality of pairs of roller units that roll the polymer composite along a first direction. Each of the pairs of roller units includes a first roller unit and a second roller unit disposed such that a center of the first roller unit and a center of the second roller unit are separated by a predetermined distance in a second direction that is perpendicular to the first direction. The pairs of roller units are disposed along the first direction such that the predetermined distance of each of the pairs of roller units increases stepwise along the first direction. The pairs of roller units strain a vulnerable portion of the polymer composite in the second direction. The testing apparatus further includes a sensor that measures stress in the vulnerable portion.

Abstract: A method for generating a thermoset Fiber-Reinforced Polymer (FRP) composite preform includes: dispensing, from a print head of a 3D-printer, a dual-cure resin coated fiber including a dual-cure resin with a ultra-violet (UV)-curable component and a thermally-curable component; curing, during the dispensing of the dual-cure resin coated fiber, the UV-curable component with a UV light source such that the dual-cure resin coated fiber is partially cured and contacting lengths of the partially-cured dual-cure resin coated fiber bond together; and positioning the print head during the dispensing and curing of the dual-cure resin coated fiber to three-dimensionally print the thermoset FRP composite preform.

Abstract: A carbon nanotube (CNT) resonator includes: a first CNT having a first end and a second end both fixed to a substrate; and a second CNT having a first end fixed to the substrate. The second CNT creates a Van der Waals (VdW) bond with the first CNT where the second CNT overlaps the first CNT. A length of the VdW bond along a distance between the first and the second CNTs oscillates based on a DC voltage applied between the first end of the first CNT and the first end of the second CNT. An electrical current passing through the first and the second CNTs using the VdW bond oscillates based on the oscillation of the length of the VdW bond.

Abstract: A fabrication method achieves bump bonds (to connect two electronic devices) with a pitch of less than 20 ?m using UV-curable conductive epoxy resin cured with an array of nano-LEDs. Nano-LEDs are devices with sizes less than or equal to 5 ?m, typically arranged in an array. After deposition of the uncured conductive epoxy layer, the nano-LED array enables a fast curing of the bumps with high spatial resolution. Next, the uncured resin is washed off and the chips are assembled, before final thermal curing takes place.

Abstract: A method, a non-transitory computer readable medium, and a system are disclosed for recommending products based on usage of one or more multifunctional printers. The method includes collecting usage data from a multifunctional printer; classifying the usage data from the multifunctional printer into one or more categories; comparing the usage data from the multifunctional printer in each of the one or more categories to usage data from one or more other multifunctional printers; determining one or more usage patterns for the multifunctional printer from the comparison of the usage data between the multifunctional printer in each of the one or more categories to the usage data from one or more other multifunctional printers; identifying one or more products or services based on the one or more usage patterns for the multifunctional printer; and recommending one or more products or services for the multifunctional printer on a graphical user interface (GUI).

Abstract: A business object model, which reflects data that is used during a given business transaction, is utilized to generate interfaces. This business object model facilitates commercial transactions by providing consistent interfaces that are suitable for use across industries, across businesses, and across different departments within a business during a business transaction. In some operations, software creates, updates, or otherwise processes information related to a cost object settlement rule and an inventory notification business object.

Abstract: A computer network architecture for making procurement-related information that has been generated on a transaction level available to data warehousing techniques is described. The network includes a transaction processing layer with at least one accounting component with a general ledger data base for centrally storing information contained in accounted-related data sets, a data warehousing layer and an additional data sourcing layer. A duplicator receives the data sets that will be or have been stored in the general ledger data base and delivers duplicates of those data sets that fulfil a predefined criteria in a procurement context. A source data base stores the duplicated data sets on a data line level. An extractor of the data sourcing layer interfaces with the data warehousing layer and selectively moves data contained in data lines or sets of data lines from the source data base to the data warehousing layer.
