黄卫星(Huang Weixing) 한양대학교 수행인문학연구소 2009 수행인문학 Vol.39 No.2
There is am important episode of “Lai Jian” in Biography of Yingying by Yuan Zhen: Yingying wrote a poet to Zhang Shen for a secret date, but flatly refused him when Zhang Sheng came for the date by climbing the wall. Why did Yingying “LaiJian” (deny the appointment)? A mainstream explanation accounting for it is “Appointment Breaking Argument”, which was retorted the theory of “Misunderstanding Argument” proposed by Jiang Xingyu. Based on the discussions of the two arguments, and the two books of Wang West Chamber and Dong West Chamber, the thesis is intended to explore the third possibility accounting for her “LaiJian”, which can be called “Attempt of experimental Probe”.

Multi-scale Local Difference Directional Number Pattern for Group-housed Pigs Recognition
( Weijia Huang ),( Weixing Zhu ),( Zhengyan Zhang ),( Yizheng Guo ) 한국인터넷정보학회 2021 KSII Transactions on Internet and Information Syst Vol.15 No.9
In this paper, a multi-scale local difference directional number (MLDDN) pattern is proposed for pig identification. Firstly, the color images of individual pig are converted into grey images by the most significant bits (MSB) quantization, which makes the grey values have better discrimination. Then, Gabor amplitude and phase responses on different scales are obtained by convoluting the grey images with Gabor masks. Next, by calculating the main difference of local edge directions instead of traditionally edge information, the directional numbers of Gabor amplitude and phase responses are encoded. Finally, the block histograms of the encoded images are concatenated on each scale, and the maximum pooling is adopted on different scales to avoid the high feature dimension. Experimental results on two pigsties show that MLDDN impressively outperforms the other widely used local descriptors.

<P>In this paper, we report a flexible comb electrode triboelectric-electret coupling nanogenerator using a separated friction microfiber object for self-powered position, motion direction and acceleration tracking sensing and its energy harvesting. The power was generated from the coupling of the electrostatic and triboelectric effects among a separated triboelectric object, a polytetrafluoroethylene (PTFE) film and interdigital electrodes. Under an acceleration of 1 m s<SUP>−2</SUP>, we found that the corona charged PTFE film with a sliding motion reached ∼3 times more short-circuit current (<I>I</I>sc) and ∼6 times more open-circuit voltage (<I>V</I>oc) than the PTFE film without corona charges, respectively. The device can be a good self-powered acceleration tracking sensor, where the reasons were a stability voltage out during the process of separated components frictions and a numerical relationship of <I>I</I>sc with increased accelerations. Moreover, potential applications using several different separated materials such as a bulk of carbon microfibers, a finger sliding with a nylon glove, and water microdrops were used to show the energy harvesting of various friction materials and their effective contact area. It was found that a much larger contact area “finger” sliding showed a <I>V</I>oc of ∼45 V, whereas a smaller contact area “microdrop” sliding on the prototype presented a maximum peak <I>V</I>oc of ∼1.8 V.</P>

Theflow patterns and corresponding breakup dynamics of solid in water in oil compound droplets underperpendicular shear force were experimentally investigated in a microfluidic device. Three typicalflowpatterns, namely double-encapsulation, plugs, and cobbles, were found and be quantitativelydistinguished by the capillary number (Cac) of continuous phase and theflow rate ratio (R) ofcontinuous phase to dispersed phase. It is found that, under all offlow regimes, the consecutive entry ofsolid particles leads d1 (the neck thickness along the center of the side channel) varying periodically. Inthe double-encapsulation regime, the neck thickness (d2) between thefirst and second particle increasesas the interface deformation recovers driven by the interfacial tension force, whereas the neck thickness(d3) between the second and third particle decreases to break off because the neck has been stretchedlong to become thin enough. As for the cobbles regime, hydrostatic pressure difference still remainsdominant, but not a shearing force. Specially, different from the W/O droplet formation, it suggests thatvarious breakup dynamics are always caused by a non-free deformation of S/W interface and the largediameter of solid particle. Finally, theflow pattern diagrams dependent on Cac and R are obtained.
