Of seekers and nonseekers: Characteristics of Covid‐19‐related information‐seeking behaviors
World Medical &Health Policy, Volume 14, Issue 2, Page 276-294, June 2022., 2022 Abstract During health crises like the coronavirus disease 2019 (Covid‐19) pandemic, it is crucial that individuals are able and willing to adequately respond to information. Individuals who deliberately seek information have an enhanced capacity to act on it and are capable of informed assessments of risks and self‐protective behaviors.

Generalized Predictive Controller of a Water Hydraulic Variable Ballast System with Solenoid Valve Model-based Compensation [PDF]
, 2017 海水液压是目前最具竞争力的可调压载系统实现方式之一，因其诸多优点，可调压载系统（WHVBS）被公认为是大深度载人潜水器浮力调节的理想方式。为提高现有WHVBS在较高采样频率下的流量控制精度，提出一种基于电磁阀特性补偿（SVC）的广义模型预测控制方法（GPC），并进行仿真验证。结果表明，较GPC所提出的GPCSVC方法能实现较高频率下的小流量精确跟踪，并能避免流量控制元件非线性带来的辨识参数振荡问题。The water hydraulics is a competitive mechanism to ...

Gaoya dianqi, 2023 温度分布是直流电缆运维检修的重要参数之一。由于高压直流输电起步较晚，高压直流电缆的研究不如交流电缆丰富、深入，因此对其温度分布影响因素的研究具有重要意义。通过Comsol有限元软件建立二维对称模型，计算±500 kV高压直流XLPE电缆稳态运行时的温度分布，求出适合电缆长期运行的载流量，并从载流量和环境温度两方面研究温度分布变化。仿真结果表明：载流量对温度分布变化具有较大的影响，当环境温度高于15℃时，导体温度约束载流量大小，环境温度低于15℃时，绝缘层最大允许温差约束载流量大小 ...
