RESEARCH OF THE PROCESSES OF NON-ISOTHERMAL FLOW OF MELTING OF A PROPYLENE BLOCKOPOLYMER WITH ETHYLENE IN THE CABLE HEAD CHANNEL

The article is devoted to the numerical study of the processes of nonisothermal melt flow of a block copolymer of propylene with ethylene in the channels of the forming tool of cable heads when two-layer insulation is applied. The influence of technological parameters on the fields of speeds and temperatures is determined

Information Transfer Capacity of Articulators in American Sign Language

The ability to convey information is a fundamental property of communicative signals. For sign languages, which are overtly produced with multiple, completely visible articulators, the question arises as to how the various channels co-ordinate and interact with each other. We analyze motion capture data of American Sign Language (ASL) narratives, and show that the capacity of information throughput, mathematically defined, is highest on the dominant hand (DH). We further demonstrate that information transfer capacity is also significant for the non-dominant hand (NDH), and the head channel too, as compared to control channels (ankles). We discuss both redundancy and independence in articulator motion in sign language, and argue that the NDH and the head articulators contribute to the overall information transfer capacity, indicating that they are neither completely redundant to, nor completely independent of, the DH.

The Design of Damping Block in the Tire Tread Extrusion Die

It is one of the keys that determining reasonable damping block geometry in the process of designing the extrusion dies. In this paper, the finite element software POLYFLOW was used to simulate the flow process of tread rubber in the head channel. In addition, the orthogonal experiment method was adopted for the optimum design of the damping block in the head channel. After optimum design, the flow velocity of rubber melt becomes more uniform in the full width at the head outlet. Consequently, the warping deformation of the rubber, which flow through the head channel, is also significantly reduced.
