Aiming at the demand of rehabilitation training of upper limb hemiplegia patients, a gesture adjustable rehabilitation training robot is proposed. The composition of the robot is described. The kinematics analysis of the designed robot mechanism is conducted, and the transformation matrix and the Jacobian matrix of various links of the robot are obtained. On the basis of the description of the robot system architecture, a controller with affected limb condition monitoring function was designed, which satisfies the trajectory tracking requirement of the robot in rehabilitation training process; and when abnormal phenomena such as twitches occur, the robot can release the bondage of the robot on the affected limb timely to avoid secondary injury to the affected limb. Experiment was conducted to verify the proposed design; the experiment results prove the effectiveness of the designed rehabilitation training robot system.

The model of rigid cascade was built up in this paper. The model has two pipe lines, and there is waste orifice plate in each stage of rigid cascade. The parameters influencing effect of rigid cascade are mainly orifice plate size and feed flow. The two factors were analyzed and compared. The calculation results indicate that the product concentration minishes with the increase of feed flow. The influence on waste was obvious. The influence of orifice plate size on the product in cascade is larger than that on waste. When the orifice plate size deviates to the original size, smaller size is chosen.

The possibility of estimating the minimum total flow in a cascade with concentrations of a target component given in the product and waste flows by means of a model match abundance ratio cascade (MARC) is studied. The parameters required to describe MARC characteristics are the total number of separation stages, the feed flow location, and the M* parameter, which is equal to a half-sum of mass numbers of the target and the supporting components. Specific research carried out independently in two scientific labs in China and Russia has demonstrated that the integral parameters of the MARC, optimized by the M* parameter, are very close to that of the optimum by the minimum total flow cascade found by means of numerical optimization. The calculation is performed for separation of krypton isotopes when the end component 78Kr and the intermediate component 83Kr are considered to be the targets. It paves the way to use the optimized MARC parameters for two purposes: first, for fast and easy evaluation of the real cascade parameters and second, as an initial guess in its further direct numerical optimization, thereby allowing significant savings in computation time. © Taylor & Francis Group, LLC.

Magnon density distribution can be affected by the spin-transfer torque in a perpendicular ferromagnetic anisotropy nanowire. We obtain the analytical expression for the critical current condition. For the cases of below and above the critical value, the magnon density distribution admits bright and dark soliton states, respectively. Moreover, we discuss two-soliton collision properties that are modulated by the current. Each magnetic soliton exhibits no changes in both velocity and width before and after the collision. © 2015 Chinese Physical Society and IOP Publishing Ltd.

Anatase TiO2 microcrystals containing ∼15% highly reactive {110} facets were successfully synthesized by a one-step hydrothermal method, in which H2O2, HF, and Cl- ions showed a synergistic effect on the formation of {110} facets. Benefiting from the surface heterojunction structure, TiO2 microcrystals with {110} facets showed an enhanced photocatalytic activity for dye degradation. © 2016 The Royal Society of Chemistry.
