Spin-torque building blocks
Nature Materials, 2014Co-Authors: Nicolas Locatelli, Vincent Cros, Julie GrollierAbstract:The discovery of the spin-torque effect has made magnetic nanodevices realistic candidates for active elements of memory devices and applications. Magnetoresistive effects alLow the read-out of increasingly small magnetic bits, and the spin torque provides an efficient tool to manipulate — precisely, rapidly and at Low Energy Cost — the magnetic state, which is in turn the central information medium of spintronic devices. By keeping the same magnetic stack, but by tuning a device's shape and bias conditions, the spin torque can be engineered to build a variety of advanced magnetic nanodevices. Here we show that by assembling these nanodevices as building blocks with different functionalities, novel types of computing architecture can be envisaged. We focus in particular on recent concepts such as magnonics and spintronic neural networks. Memory devices based on the spin-transfer-torque effect offer a range of attractive properties, such as speed of operation and Low Energy Cost. This Progress Article outlines a strategy for assembling different nanodevices based on the spin-torque effect to achieve qualitatively different computing architectures.

Low Energy Cost reference trajectories for a biped robot
International Conference on Robotics and Automation, 1998Co-Authors: Christine Chevallereau, Alexander Formalsky, B PerrinAbstract:The impulsive torque at the beginning and end of the ballistic motion between these two instants give energetically optimal motion for a pendulum. Many authors assume that in human walking, muscle activities alternate with some periods of relaxation. From these two arguments, we assume that a motion defined by ballistic motion and impulsive control at dual support instances will lead to an energetically economical trajectory. Optimal configurations are defined, and smooth changes on the reference trajectory are proposed to obtain a trajectory which can be folLowed with finite torques. The physical constraints on the reaction forces to avoid take off or sliding of the biped walking robot, and saturation on the torques produced by the actuators are explicitly taken into account.

Pinning synchronization with Low Energy Cost
Communications in Nonlinear Science and Numerical Simulation, 2014Co-Authors: Fuzhong Nian, Qianchuan ZhaoAbstract:Abstract The pinning synchronization on complex networks with Low Energy Cost was investigated. Two basic problems were considered, in this paper. One is how to achieve synchronization on complex network with weak coupling. Another is how to reduce the Energy Cost in the process of achieving and keeping synchronization. On the other hand, for a good pinning strategy, the synchronizing speed should also be ensured. In this paper, a switching pinning strategy was proposed to enhance the synchronizing speed. And from the point of view of Energy saving, some selected links were strengthened. Theoretical analysis and simulations on different complex networks indicate that the proposed pinning strategy is effective. Compare with conventional existing method, the superiority of our method is significant.
