Hodological patterning as an organizing principle in vertebrate motor circuitry by Joel C. Glover

“…In vertebrate motor circuits, hodological patterning has been demonstrated at different levels, from the final motor output of somatic and preganglionic autonomic neurons targeting peripheral motoneurons and ganglion cells, to premotor inputs from spinal and brainstem neuron populations targeting the somatic motoneurons and preganglionic autonomic neurons, to cortical neurons that delegate movement commands to the brainstem and spinal neurons. …”

Massive MIMO LEO Satellite Communications System by Kexin LI, Li YOU, Xiqi GAO

“…Extending massive multiple-input multiple-output (MIMO) technique to low earth orbit (LEO) satellite communication systems enables satellites to implement fl exible beamforming, which can make full use of the spatial degrees of freedom of massive MIMO and signifi cantly improve the spectral effi ciency and energy effi ciency of LEO satellite communication systems.Several related issues in massive MIMO-based LEO satellite communication systems were studied.The characteristics of massive MIMO LEO satellite channels were analyzed.The important diff erences between them and terrestrial wireless channels were revealed.With the aim of addressing the problems on channel information acquisition, multi-user transmission and user scheduling in massive MIMO LEO satellite communication, the main difficulties faced by the current work were discussed, and how to use the characteristics of massive MIMO LEO satellite channels to design tailored solutions with low implement complexity was conceived.…”

Indoor BLE and MEMS based multi-floor fusion positioning algorithm by Mu ZHOU, Bin WANG, Zeng-shan TIAN, Qian-kun ZHANG

“…Based on the data fusion from micro electro mechanical system (MEMS) sensors and low-power bluetooth (BLE),an indoor BLE and MEMS based multi-floor positioning algorithm was proposed.First of all,the affinity propagation clustering,outlier detection and received signal strength indicator (RSSI) filtering algorithms were applied to denoise the fingerprint database.Second,by using the extended Kalman filter,the robust M estimation algorithm was used to perform the optimal estimation of the two-dimensional target position.Finally,the barometer output and geographical position information was considered to realize the height estimation of the target.The experimental results show that the proposed system is able to achieve the horizontal and vertical positioning errors lower than 0.7 m and 0.35 m respectively in multi-floor fusion positioning.…”

Dynamics Analysis of the Crank and Connecting Rod Mechanism with Clearance and Flexibility by Tingting Li, Zhenshan Zhang, Guohua Cui, Lianzhe Guan

“…On this basis，the influence of clearance size，connecting rod flexibility and their coupling on the mechanism dynamics output response is systematically studied. The results show that，within the same cycle，the collisions are mainly concentrated in the early stage of the campaign close to the two sides of the crank，the connecting rod clearance increases，the collision between articulated components intensify，the oscillation amplitude of impact force and the embedding depth of increase obviously，and the stability of the axis trajectory is reduced，and the appropriate component flexible processing can reduce collisions caused by clearance joint.…”
