  • SNPD – On higher-order communication of Erlang
    2016 17th IEEE ACIS International Conference on Software Engineering Artificial Intelligence Networking and Parallel Distributed Computing (SNPD), 2016
    Co-Authors: Xian Xu

    Abstract:

    Erlang is a concurrent Functional programming language and is used to program concurrent, distributed and fault-tolerant systems. In this paper, we study the higher-order communication mechanism of Erlang’s Functional programming, which is actually achieved by means of sending the references to Functions in the current implementation. We propose an improved design. In this design, we realize purely higher-order communication, i.e., strict program-passing. Moreover, we realize automatic determination of module dependency and simplification of communicating Anonymous Function, i.e., only sending the definition of Anonymous Function instead of the entire module. Finally, experiments are designed to test the implementation.

  • Anonymous Function Method and its Application in Screw Pump’s Design and Processing
    Applied Mechanics and Materials, 2011
    Co-Authors: Yuan Xun Zhang, Qian Tang, Xian Zhi Ye

    Abstract:

    Matlab Anonymous Function method combining graph with analytical method was proposed in this paper, which was based on the low solving efficiency and low precision of trigonometry transcendental equation for shape line design and sectional profile calculation of screw pump rotor. Parameters of Anonymous Function can be nested within each other to solve enveloping conditional formula of shape design or intersecting line of sectional profile design for screw pump, the process of which only took several seconds with high precision of 10E-08mm. What’s more, this method could also be adopted in the forming tool design with spiral cross section, which could largely improve design efficiency and calculation precision.

  • Optimal design of screw and flow field analysis for twin-screw pump
    Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011
    Co-Authors: Qian Tang, Yuan Xun Zhang, Linqing Pei, Jiong Tang

    Abstract:

    A new solving transcendental equation method combining graphics and analyzing approach—Matlab Anonymous Function Method (MAFM) was developed to solve the screw contact line equation. The influence of contact line on screw sealing property was revealed and the effect of involute meshing angle on the screw contact line properties of type A twin-screw pump was investigated. The tooth profiles, spiral surface equations and contact line equations of type A twin-screw pump were obtained based on the optimal involute meshing angle. The three dimensional model and flow field digital model with modified involute meshing angle for screw rotors was developed to analyze the pressure field, velocity field and other screw pump’s characteristics by applying finite volume method, and the volumetric efficiency of flow channel for twin-screw pump study has been gained. The study provides the theoretical basis for the further screw pump development and property evaluation.Copyright © 2011 by ASME
