Abstract To enhance the sensitivity of graphene aerogel‐based piezoresistive sensors by weakening their compressive strength while keeping elasticity, lightweight and lamellar aerogels (LGAs) with high elasticity satisfactory electrical conductance networks are fabricated bidirectional‐freezing aqueous suspensions oxide in presence small amounts organic solvents, followed lyophilizing thermal annealing. Because structure LGA, its along direction perpendicular to surface is much lower than...
Abstract To alleviate resource shortage and environmental pollution, solar energy can be converted into thermal stored in phase change materials turn generate electrical energy. enhance the utilization efficiency of solar‐thermal‐electrical conversion devices prevent heat loss to environment at night, an intelligent solar‐responsive phase‐change system is innovatively designed consisting a graphene aerogel film/paraffin wax stamen with ultra‐high conductivity 46.7 W m −1 K , thermally...
Abstract Thermally conductive polymer composites hold great potential for thermal management applications in the electronics industry, but achieving metal‐like conductivity (>200 W m −1 K ) remains challenging due to inevitable phonon scattering and resistance at filler‐filler filler‐matrix interfaces. Herein, an efficient approach is presented overcome this long‐standing barrier by designing a densified interconnecting filler framework, featuring macro‐level carbon fiber (CF) array...
The nonlinear transmission line is a structure where short-duration pulses called electrical solitons can be created and propagated. By combining, in closed-loop topology, the special amplifier that provides not only gain but also mechanisms to tame inherently unruly soliton dynamics, we recently constructed first oscillator self-generates stable, periodic train of (Ricketts , IEEE Trans. MTT, 2006). This paper starts with review this introduced circuit concept, then reports on new...
Abstract The mechanical defects (scratches/cracks) originated from grinding processing need to be dislodged so that improving the optical performance of fused silica. In this paper, HF‐based (HF represents hydrofluoride acid) etchant was used as a subsequent fabrication for loose‐abrasive ground silica, and surface morphology characteristics samples were evaluated, meanwhile, electric/light field distribution around treated cracks simulated using finite difference time domain (FDTD) method....
Visual measurement technology has been widely used in fields such as industrial production or and monitoring. Camera calibration is a very important link of visual measurement, because it directly determines the accuracy precision measurement. It often does not need extremely high-precision but simple, rapid, effective many engineering surveys. Therefore, camera self-calibration technique really needed. The advantages are that any target complex mechanical structure to control camera's...
AbstractThis paper examines the impact of information communication technology (ICT), human capital, and resource management on labour productivity growth in Canadian tourism/hospitality industries using Workplace Employee Survey from 1999 to 2005. Feasible generalized least squares method moments estimations are applied model. The empirical results show that Solow paradox does exist these industries. Adoption ICT not significantly improve productivity. evidence shows capital is a...
While the use of sinusoidal electromagnetic waves as information carriers is taken one principal axioms today's wireless system design, certain nonsinusoidal may further enrich scope and capacity modern engineering. Two notable nonsinusoid examples are impulses chaotic signals. The short temporal width has enabled applications such ranging radars ultra wideband (UWB). complex nature signals offers a new means encrypted communication. Here we review circuit paradigm, electrical soliton...
Accurate and robust classification methods of sea ice open water are significant for many applications. Synthetic Aperture Radar (SAR) imaging capability is independent weather conditions widely used in classification. U-Net, a deep learning framework, has achieved great success the field biomedical image In this study, we construct U-Net-based "end-to-end" model to classify pixels SAR imagery. Five images acquired Gulf Alaska near Bering Strait case study. We manually label as water. The...
The next generation of all-optical computation platforms prefers the light-guiding-light (LGL) scheme inside a medium that envisions circuitry-free and rapidly reconfigurable systems powered by dynamic interactions between light beams. Currently, suitable LGL materials corresponding mechanisms are in urgent need. In this work, we proposed ubiquitous air as restorable signal manipulation with transient air-plasma waveguide circuits. Briefly, focusing femtosecond laser beams free space,...

A multiscale Lucas-Kanade (LK) approach presented build correspondence between map points robustly efficiently. Thereafter, system put forward long-distance localization ground vehicle. The main...
Abstract In China, large commercial complex is a new type of building with complicated business and high energy consumption. The performance significantly depends on the ventilation, which affected by air infiltration through uncontrolled leakage across envelope. It important for improving reducing conditioning load to learn rate in complex. Currently, testing method commonly used some cases fails measure continuously period time. this paper, using principle mass balance relationship between...

This paper introduces a robust self-sustained electrical soliton oscillator that combines nonlinear transmission line (NLTL) and unique amplifier. The amplifier uses non-linear transfer function an adaptive bias control to work in cooperation with the dynamics of NLTL. system reproducibly self-generates stable pulse trains. Experimental results are presented together description stability mechanisms.
Over the past three hundred to four years, Taiwan has lived through a unique historical experience: (1) it been frequently subjected outside rulers; (2) given its geographic location, cultural characteristic is oceanic rather than continental; (3) began as an immigrant society only be gradually localized time went on.
