Acupoints positioning and tracking technology (APTT) is the key technology of Chinese massage robot (CMR) and the premise to ensure the efficacy of massage. Research status of APTT are introduced, with emphasis on APTT based on vision, based on template matching (TM), and based on Back-Propagation neural network (BPNN). Moreover, the shortcomings of existing techniques and the prospect of the techniques are discussed in this paper.

Abstract

The design of mechanism scheme is the primary phase and the creative and challenging part in product lifecycle. In this paper, we research the multiple attribute group decision making (MAGDM) problems for evaluating the design of mechanism scheme with uncertain linguistic variables. We employ the uncertain linguistic weighted harmonic mean (ULWHM) operator to aggregate the uncertain linguistic information corresponding to each alternative and get the overall value of the alternatives, then rank the alternatives and select the most desirable one(s) by using the formula of the degree of possibility for the comparison between two uncertain linguistic variables. Finally, a practical example for evaluating the design of mechanism scheme is used to illustrate the developed procedures.

The article discusses a new technology of terminal processing of container traffic, which involves direct transfer of containers by rail mounted gantry cranes between groups of railcars instead of additional shunting procedures for their selection before supplying and withdrawal at loading and unloading railway tracks. In order to implement the accessibility to the gantry crane span, the additional loading and unloading railway track is introduced, intended to discard incoming containers by a gantry crane and their transhipment to the trains marshalling in the specific destination. This technology is applicable in the organization of container trains in regional distribution and storage centers and in the implementation of modal container block-trains with loading and unloading procedures in the same direction. Based on the analysis of technical development of the terminal network, the opportunity of implementing the proposed approach on Russian railways has been provided. The effect of this innovative technology is proposed to be evaluated from the perspective of decreasing the duration of rolling stock handling and, accordingly, reducing the operating costs of a terminal. The simulation of the terminal processing time of a container flow with the traditional and new approaches was carried out on the basis of the Monte Carlo method. On the basis of modeling, the dependence of the magnitude effect size on the number of the containers transhipped is determined.
