Abstract: Disclosed are an apparatus and method for control of 3D printing. The apparatus includes a color data generation unit configured to generate entity-specific color data representing a color of each entity forming a 3D object based on modeling information about the 3D object, a color quantization unit configured to convert the entity-specific color data to represent one of a plurality of output-able colors as the color of each entity, and an output file generation unit configured to generate an output file to be used for output of the 3D object from the modeling information and the converted entity-specific color data.

Abstract: A three-dimensional printing control apparatus and method is provided. The apparatus comprising: a control command generator configured to: generate a control command for outputting a three-dimensional object having a first shape, and generate, in response to a request for changing a shape of the three-dimensional object from the first shape to a second shape is received while performing a output work for the three-dimensional object, an additional control command for outputting a changed three-dimensional object having the second shape; and a control command transmitter configured to, in response to determining that it is possible to output the changed three-dimensional object through the output work, substitute the additional control command for the control command with respect to a non-printed portion of the three-dimensional object.

Abstract: A powertrain of a hybrid vehicle may include a planetary gear set, a first motor unit and a second motor unit. The planetary gear set may include three rotary members in which one rotary member is connected to an engine and another rotary member is connected to a front driveshaft. The first motor unit is connected to the remaining rotary member in the three rotary members, and the second motor unit is connected to a rear driveshaft and supplying power to the rear driveshaft.

Abstract: An apparatus for controlling 3D printing includes an output determiner configured to determine, after generating a first control command to output a 3D object, whether an additional 3D object is able to be output through an output task for the 3D object, and a control command generator configured to generate a second control command to output a not-yet-output part of the 3D object and the additional 3D object if it is determined that the additional 3D object is able to be output through the output task.

Abstract: Provided is a cluster system including a first physical server having registered therein an active virtual machine; and a plurality of physical servers, wherein the plurality of physical servers comprises a second physical server having registered therein a standby virtual machine corresponding to the active virtual machine, the active virtual machine failing over to the standby virtual machine when a failure occurs in the first physical server, wherein each of the plurality of physical servers stores post-failure registration information when the failure occurs, wherein the post-failure registration information associates the active virtual machine with a physical server among the plurality of physical servers, and wherein the physical server is different from the second physical server.

Abstract: New types of photocatalyst materials are disclosed together with methods for preparing and using these materials, as well as air treatment systems incorporating such materials. The photocatalyst materials of this invention consist essentially of very small particles of a first-metal oxide, the first-metal being a metal that exhibits photo-induced semiconductor properties, having ions of a second-metal dispersed throughout its lattice structure, the second-metal being selected from the group of dopant metals. Such photocatalyst materials are prepared by the steps of mixing first-metal and second-metal precursors, removing nonessential ions from the mixture, drying the resulting product, and calcinating the dried product to produce the completed photocatalyst material.

Abstract: Water discharged at a top region of an eliminator flows, e.g., by gravity into, along, and between the portions of the eliminator while an air flow also travels therein, e.g., horizontally and transverse to the water flow. As the air flow encounters the water, e.g., strikes portions of the eliminator having water flowing downward therealong or encounters water falling between portions of the eliminator, contaminants pass from the air flow to the water flow. The air flow, relieved of certain contaminants, continues onward and the water flow collects at the bottom of the eliminator for filtration and re-circulation through the eliminator.
