摘要： A packet transmission apparatus includes a transmission unit dividing input data and transferring segments, which are obtained by adding sequence numbers to the respective pieces of the divided data, a switch unit transferring the segments to one of a plurality of reception units, and a reception unit reconstructing an original input packet from the plurality of segments that arrive from the switch units on the basis of the sequence numbers. The reception unit includes a packet buffer storing segments that arrive from the switch units, a determination unit determining, on the basis of the sequence number, whether the segment stored in the packet buffer is to be discarded; and a discard part reading the segment stored in the packet buffer in an order from the segment having an older sequence number and discarding the segment that is determined to be discarded.

摘要： An optimization model analysis apparatus configured with a finite element model generation unit that generates on the basis of a structural configuration of a design model having a 3D shape a finite element model for analyzing acoustic characteristics of the design by a finite element method. The apparatus is configured with a shell model generation unit that generates a model by dividing a surface of the finite element model into a plurality of plate elements having a polygonal shape; an optimization model generation unit that superimposes the shell model on the surface of the finite element model to generate an optimization model; and an optimization model modification unit that displaces nodal points which serve as vertexes of the plate elements in a direction intersecting a plane of the plate elements by displacing at least one of the nodal points in a direction of reducing a thickness of the optimization model.
