This study created a new type of inflatable metamorphic origami that has the advantage being highly simplified deployable system capable realizing multiple sequential motion patterns with monolithic actuation. The main body proposed unit was designed as soft chamber sets contiguous/collinear creases. In response to pneumatic pressure, motions are characterized by an initial unfolding around first set creases followed another second Furthermore, effectiveness approach verified constructing...

With flexibility...
In this paper, the semi-global exponential stability of semi-Markov jump systems with distributed delay under sampling control is studied. Besides, a new definition functional derivative associated given. By using global system continuous control, incorporation inequality technique, criteria are given, including Lyapunov-type theorem and coefficient-type theorem. Eventually, an application about class oscillator combining theoretical results discussed corresponding numerical example...
Image-based mechanical modeling of the complex micro-structure human bone has shown promise as a non-invasive method for characterizing strength and fracture risk in vivo. In particular, elastic moduli obtained from image-derived micro-finite element (μFE) simulations have been to correlate well with results by testing cadaveric bone. However, most existing large-scale finite-element simulation programs require significant computing resources, which hamper their use common laboratory...
Flexible robots have been widely used in minimally-invasive surgery because of their dexterity and accuracy. However, the torsion end-effector under bending state usually produces unnecessary concomitant motion robot arm. This letter proposes a novel design <i>in-situ</i> torsionally-steerable tendon-driven flexible for otolaryngology surgery. kind three modes: pure torsion, fusion modes. Among them, mode provides torsional which can maintain position approach vector during operation. A...
This paper researches the path tracking problem for four-wheel steering (4WS) autonomous vehicles (AVs). A 4WS dynamics model of error is established. An analysis steady state point that AVs can eliminate in ideal condition but traditional Front-Wheel (FWS) cannot achieve. By introducing sideslip angle, two sliding mode controllers are utilized to converge lateral offset and heading zero keep vehicle stability extreme condition. J-turn test a single lane change conducted CARSIM-Simulink...
Flexible robots with <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">in-situ</i> torsion can be used in laryngeal endoscopic surgery which maintain the position and approach vector of end-effector during operation. However, inherent errors would produced by torsional motion are different due to various configuration serpentine module robot.

In this paper, synchronisation between multi-links stochastic delayed drive complex networks with semi-Markov jump and the corresponding response via hybrid multi-delay impulsive control is researched. Thereinto, impulses include synchronous asynchronous without delay, multi delays. We put up a concept of average gain to quantify effects. A novel differential inequality also established. Utilizing it, combining Lyapunov method graph theory, we provide two sufficient criteria make achieve...
In this letter, a novel folded monopole antenna with an ultrawideband (UWB) bandwidth and omnidirectional radiation performance has been proposed. An inverted “S”-type structure was formed by folding the planar monopole, which not only realizes dimension reduction, but also contributes to decrease in size of ground plane; proposed antenna, meanwhile, more circular pattern frequency ratio 3.4:1, compared antenna. Simulation carried out together measurement fabricated Good agreement between...
This paper addresses the problem of moving dim target detection in radar systems using track-before-detect approaches (TBD), which are implemented by a fast Viterbi algorithm (FVA). Traditional algorithms (VA) traverse all resolution cells including many noise every frame, whereas FVA improves searching method combining with Constant False Alarm Rate (CFAR) approach to expel cells, and provides same performance much less computational cost. What's more, it avoids extend no post-processing...
摘要: 针对振动条件下系统级封装(System in Package,SiP)器件的振动可靠性问题,利用ANSYS软件进行随机振动仿真,并对模型进行参数校正从而获得器件的随机振动疲劳寿命。首先,采用Surface Evolver软件对鸥翼形引脚焊点形态进行预测,并将模型数据导入ANSYS中完成模型建立;进行不同载荷量级的正弦振动试验,对SiP器件模型进行材料参数校正,并对校正后模型进行振动仿真,获得危险点应力数据,结合试验所得的疲劳寿命数据拟合得到材料的S-N曲线;最后,通过随机振动仿真分析确定器件危险薄弱点,通过S-N曲线和Dirlik寿命预测模型,得到SiP器件的随机振动可靠性寿命。本文介绍了针对SiP器件的随机振动可靠性试验及模拟结果,提出了针对器件寿命的评价通用方法,为器件在整机应用条件下的寿命评价提供理论依据。
