Prediction of interface dielectric relaxations in bimodal brush functionalized epoxy nanodielectrics by finite element analysis method

2022 IEEE Conference on Electrical Insulation and Dielectric Phenomena (CEIDP) (2014)

Yanhui Huang Timothy Krentz J. K. Nelson Linda S. Schadler Yang Li

Finite element 2-D analysis was implemented to simulate the dielectric spectra of nanodielectrics. As a test case, silica modified with a high graft density of short molecules and a low graft density of epoxy compatible chains were incorporated into epoxy. TEM images of the composites filler distribution were used to construct the model geometry with the interfacial area specifically included. The interfacial area was found to have dielectric relaxation behavior different from that of the matrix, as described by additional fitting parameters. This modeling method has the potential to improve our understanding of the impact of interface properties on the dielectric properties of composites.

Luminance stepped decreasing ratio of the tunnel entrance enhanced lighting based on visual performance

Applied Optics (2022)

Cheng Kang Zhigang Du Guojun Lin Chi Zhang Zhiyi Huang

To achieve a safe and comfortable entrance enhanced lighting environment of tunnels, visual performance experiments under the dynamic and static luminance environments were carried out to investigate the influence of the luminance variation forms and stepped decreasing ratio k' of the tunnel entrance enhanced lighting on the driver's comprehensive visual performance. The application effect was further verified by real vehicle experiments and field luminance measurements. The results of the dynamic and static experiments show that compared with the continuous and smooth decrease of the luminance according to the International Commission on Illumination (CIE), when facing the stepped decrease of luminance, drivers tend to withstand greater visual operation stress and a more tense psychological state. After the stepped decrease of the luminance, the driver's average and instantaneous reaction both slow down, while the amplitude of the slowdown decreases with the increase of k' and increases with the increase of the luminance level. The results of the real vehicle experiments show that increasing k' of Threshold Zones 1 and 2 and Transition Zones 1 and 2 to 0.7, 0.6, 0.5, and 0.5, respectively, can effectively relieve driver's psychological tension and enhance the visual performance. For practical engineering applications, it should be combined with daylight reduction facilities, thus avoiding the increase of energy consumption of the tunnel entrance enhance lighting.

Falconer

Gang Wu Mengdong Yang Ke Wu Guilin Qi Yuzhong Qu

Falconer is a semantic Web search engine enhanced SIOC (Semantically-Interlinked Online Communities) application, which is designed to demonstrate the ability of accelerating the creation and reuse process of semantic Web data with easy-to-use user interfaces. In this process, semantic Web search engines feed existing semantic data into the SIOC framework, where new semantic data are composed by the community and indexed again by those search engines. Compared to existing social (semantic) Web applications, Falconer inherently conforms to SIOC specification. It provides semantic search engine based user registration suggestion, friends auto-discovery, and semantic annotation for forum post content. Another distinctive feature is that it enables users to subscribe any resource having a URI as the topic they are interested in. The relationships among users, topics, and posts are further visualized for analyzing the topic trends in the community. As all semantic data are formatted in RDF and RDFa, they can be queried with SPARQL query language.

A Biomimetic Adhesive Disc for Robotic Adhesion Sliding Inspired by the Net-Winged Midge Larva

Soft Robotics (2024)

Haoyuan Xu Jianhai Zhi Bohan Chen Shuyong Zhao Jie Huang

Net-winged midge larvae (Blephariceridae) are known for their remarkable ability to adhere to and crawl on the slippery surfaces of rocks in fast-flowing and turbulent alpine streams, waterfalls, and rivers. This remarkable performance can be attributed to the larvae's powerful ventral suckers. In this article, we first develop a theoretical model of the piston-driven sucker that considers the lubricated state of the contact area. We then implement a piston-driven robotic sucker featuring a V-shaped notch to explore the adhesion-sliding mechanism. Each biomimetic larval sucker has the unique feature of an anterior-facing V-shaped notch on its soft disc rim; it slides along the shear direction while the entire disc surface maintains powerful adhesion on the benthic substrate, just like the biological counterpart. We found that this biomimetic sucker can reversibly transit between "high friction" (4.26 ± 0.34 kPa) and "low friction" (0.41 ± 0.02 kPa) states due to the piston movement, resulting in a frictional enhancement of up to 93.9%. We also elucidate the frictional anisotropy (forward/backward force ratio: 0.81) caused by the V-shaped notch. To demonstrate the robotic application of this adhesion-sliding mechanism, we designed an underwater crawling robot Adhesion Sliding Robot-1 (ASR-1) equipped with two biomimetic ventral suckers. This robot can successfully crawl on a variety of substrates such as curved surfaces, sidewalls, and overhangs and against turbulent water currents with a flow speed of 2.4 m/s. In addition, we implemented a fixed-wing aircraft Adhesion Sliding Robot-2 (ASR-2) featuring midge larva-inspired suckers, enabling transit from rapid water surface gliding to adhesion sliding in an aquatic environment. This adhesion-sliding mechanism inspired by net-winged midge larvae may pave the way for future robots with long-term observation, monitoring, and tracking capabilities in a wide variety of aerial and aquatic environments.

Optimization Strategy for Sheath Circulation Inhibition of Parallel Laying Cable Lines

Advances in transdisciplinary engineering (2024)

Ke Wu Yu Xu Lin Cheng Shi Yan Wu Jian

With the development of cities, the application of high-voltage cables in cities is becoming more and more extensive. The induced voltage generated during the operation of the cable will affect the normal operation of the cable line, and when the cable sheath takes grounding measures, it will form a loop with the earth, and at this time, a current will be formed in the sheath, which will make the cable temperature rise, and in serious cases, it will lead to cable failure and affect the stability of the power system. Based on the ATP-EMPT platform, this paper carries out the simulation analysis of two grounding modes of single-end grounding and medium-indirect grounding of parallel laying cable lines. The simulation results show that when the resistance of the ground resistance is approximately equal to the equivalent resistance of the cable sheath, the circulation current can be effectively suppressed. The recommended laying length of the two laying methods is not more than 6km for single-end grounding and 12km for intermediate direct grounding.

Home Country Institutions and Legitimacy on Chinese High-Tech MNEs’ Entry Mode Choices: A Conceptual Framework

International Journal of Advanced Research in Economics and Finance (2023)

Ningxin Cao Shankar Chelliah Ke Wu

The institutional factors of the home country play an increasingly important role in the process of the rise of MNEs in developing countries. A Through studies in literature, this paper finds that domestic institutional support and institutional restrictions can effect the entry mode of Chinese high-tech enterprises into the target country's market, and the legitimacy of enterprises in the target country plays an intermediary role between the two. The hypothesized effect of variables and entry mode choice of Chinese high-tech MNEs needs to be tested in future research based on survey data drawn from official sources and questionnaires. This study expanded the theoretical tools that determine the decisions of the FDI entry mode.
