It has been experimentally found that when amphiphilic surfactants are added to polyethylene (PE), water tree initiation, especially that of bow-tie trees (BTTs), is suppressed. In this study, we analyze the intermolecular interactions among PE, amphiphilic surfactants, and water molecules by molecular dynamics (MD) simulation and quantum chemical calculation. Moreover, we confirm that the surfactants and water molecules form a reverse micelle, and investigate the effect of the presence or absence of an electric field.

Prior to the deep learning era, shape was commonly used to describe the objects. Nowadays, state-of-the-art (SOTA) algorithms in medical imaging are predominantly diverging from computer vision, where voxel grids, meshes, point clouds, and implicit surface models are used. This is seen from numerous shape-related publications in premier vision conferences as well as the growing popularity of ShapeNet (about 51,300 models) and Princeton ModelNet (127,915 models). For the medical domain, we present a large collection of anatomical shapes (e.g., bones, organs, vessels) and 3D models of surgical instrument, called MedShapeNet, created to facilitate the translation of data-driven vision algorithms to medical applications and to adapt SOTA vision algorithms to medical problems. As a unique feature, we directly model the majority of shapes on the imaging data of real patients. As of today, MedShapeNet includes 23 datasets with more than 100,000 shapes that are paired with annotations (ground truth). Our data is freely accessible via a web interface and a Python application programming interface (API) and can be used for discriminative, reconstructive, and variational benchmarks as well as various applications in virtual, augmented, or mixed reality, and 3D printing. Exemplary, we present use cases in the fields of classification of brain tumors, skull reconstructions, multi-class anatomy completion, education, and 3D printing. In future, we will extend the data and improve the interfaces. The project pages are: https://***/ and https://***/Jianningli/*** Codes 68T01 © 2023, CC BY.

Memristive crossbar arrays are finding application in a wide range of operations such as memory, in-memory-computing, analog computing, etc. The crossbar performance is limited by a sneak path current, which limits the array size and negatively affects power and noise margin. In this paper, we present a synthesis of one selector and one Memristor device (1S1R) unit based on nonlinear resistive selector connected in series with bipolar Memristor (MR) element. The selector provides a gating function to the MR to reduce the sneak path current. The operation and performance of the MR and the selector devices have been verified individually and when serially connected. The MR cell measurements show good repeatability over multiple SET-RESET cycles with Von ~ 2.5 to 3 V, Roff/Ron ~ 10 4 and Voff ~ -0.6 to -1.5 V. The electrical parameters of the memristor cell have been extracted and correlated mathematically using the Voltage-Threshold Adaptive Model (VTEAM). Various array sizes ranging from 2 ×2 to 4,000×4,000 have been investigated using spice circuit simulator. The results show that the proposed configuration reduces the sneak path by 200 times when compared with a similar size array that does not use a selector device. Also, using the selector increases the crossbar read margin, device selectivity, and enables high memory array density up to 4k×\pmb4k compared to 512 x512 state of the art. The device allows relatively low voltage operation of 4V/1V (write/read) compared to 5V/2V reported in literature, which makes it attractive for low power applications.

The strain on a single FBG sensor, integrated into a single layer of Kevlar mounted behind a Kevlar soft body armor coupon, is measured throughout a ballistic impact event. The strain is collected through high-speed, full-spectral interrogation of the FBG during the event. The use of the wavelength shift and spectral distortion of the FBG provides a description of the strain profile and interaction between the optical fiber and Kevlar fabric. The measurements are correlated to high-speed camera images taken from the rear and side of the armor coupon. In future testing, this information can be applied to identify the sequence of energy dissipation mechanisms enacted within the armor to resist the ballistic impact. © OSA 2018 © 2018 The Author(s)

Plates vibrate when load moves on them. In this paper, the dynamic response of Mindlin plate analytical model was converted to its numerical form using finite difference algorithm. The numerical model was analysed to ascertain the critical parameters contributing to the deflection of Mindlin plate under a moving load. The examination was more reasonable as in the likelihood of the plate laying on a Pasternak foundation was put into thought. Likewise the impact of damping was not dismissed. The plate considered in this paper was an inclined Mindlin plate, where the impacts of shear deformation and rotatory inertia were considered. The numerical equations were solved with the help of a developed computer program and Matlab. The results were consistent with what we have in the literature. The effects of the Pasternak foundation, damping, angle of inclination, and the moving load to the dynamic response of the elastic plate were exceptionally self-evident.

The conventional PID controller cannot have a satisfactory performance when it has been applied in the nonlinear system. In this paper, GCAQBP algorithm for complex-valued neural networks is proposed in control system. The approach based on an artificial neural network (ANN) is presented for control system. The ANN model is based on GCAQBP (Globally Convergent Adaptive Quick Back Propagation) algorithm. The method adopts the advanced algorithm of BPNN for nonlinear system to estimate the parameters of PID, increase the control signal and reduce the error results. Simulations show it has high robustness, simulation results are also presented to exhibit the effectiveness of the proposed GCAQBP algorithm. © 2018 Indian Pulp and Paper Technical Association.

Bound states in the continuum (BICs) have attracted much attention in recent years due to the infinite quality factor (Q-factor) resonance and extremely localized field. In this study, BICs have been demonstrated by dielectric metasurfaces with hybrid surface lattice resonance (SLR) in the experiment. By breaking the symmetry of geometry, SLR can be easily switched between BICs and quasi-BICs. Comparing with literature, switching between BICs and quasi-BICs is usually accompanied by wavelength shift. Here, a design rule is proposed to prevent the wavelength shift when the Q-factor is changing. Also, such a design also makes subsequent identification of the laser threshold more credible. Due to the high Q-factor, low threshold laser is one of the intuitive applications of BICs. Utilize the high localized ability of BICs, low threshold BICs laser can be achieved by the dielectric metasurface immersed with Rhodamine 6G. Interestingly, due to the high Q-factor resonance of BICs, the laser signals and images can be observed in almost transparent samples. Not only the BICs laser is demonstrated in the experiment, but also the mechanism of BICs is deeply analyzed. This study can help readers better understand this novel feature of BICs, and provide the way for engineer BICs metasurfaces. The device can provide various applications, including laser, optical sensing, non-linear optics enhancement, and single-photon source. Copyright © 2020, The Authors. All rights reserved.

Gas leakage commonly happens in daily life. The leakage can cause many losses and even cause the death. Implementing human and animals in monitoring, checking, and finding the source of leakage can harm their life. The usage of the robot can give many advantages, i.e., it can be programmed easily, it does not feel tired, it does not need much time to be trained, etc. However, to control the robot in navigating to the leakage source is not so Haeasy. In this research, an enhancement of navigation system using two parameters inputs, i.e., distance and concentration of the gas is proposed. A distance fuzzy algorithm and gas fuzzy algorithm is implemented to the robot. The robot can use each parameter depends on the environment and situation that it meets. Both of the algorithms were successful in guiding the robot to move in the correct path. The robot could avoid the obstacles and find the location of the gas leakage.

The present study experimentally proposes separation control around a pitching airfoil with burst (duty cycle) actuation of a wide range of the burst frequency using a dielectric barrier discharge plasma actuator. Experiments are conducted using a two dimensional NACA0015 (c = 100 mm) airfoil with the chord based Reynolds number of 63,000. The airfoil pitches from 5 deg to 25 deg with fluctuation frequency of 2 Hz corresponding to reduced frequency of 0.02π. A plasma actuator are installed at the leading edge and driven in continuous and burst modes with F+ = 0.5 - 60. Flow field is evaluated with unsteady pressure measurement. From the results, three control effects 1) delay of dynamic stall, 2) CL increase in the pitch-down phase, and 3) promotion of reattachment in the pitch-down stage are observed in burst actuation for a pitching airfoil. © 2018, AIAA Aerospace Sciences Meeting.
