Paper-like materials have found widespread applications in various fields, especially recently emerging applications in biomedicine as paper-based devices, where liquid wicking behavior plays a significant role. Although tremendous experimental evidence has indicated that fluid control is a key technology to improve the performance of these paper-based devices, the underlying mechanisms of liquid...
In practice, unlabeled data can be cheaply and easily collected from target domain, but it is quite difficult and expensive to obtain a large amount of labeled data. Therefore how to use both of labeled and unlabeled data to improve the learning performance becomes critical issue for many real-world applications. Active Learning and Semi-supervised Learning are right solutions to such problem, and...
Considering the strong uncertainties of aerodynamic parameters and atmospheric environment and the large dynamic variation during the Reusable Launch Vehicle (RLV) reentry process, this paper introduces an attitude controller design method which combines Linear Quadratic Regulator (LQR) with Fuzzy Gain-Scheduling (FGS). The whole operating envelope is divided into several design points firstly. And...
The writer discusses the three main strategies for entrepreneurs: innovation in advanced technology, high-tech introduction, keeping traditional procedure, theoretically. The writer also compares which strategy could be the best under different cases, and points out that these 3 fundamental strategies is a “basis” of the “strategy space”, as the best strategy may be a linear combination of these 3...
Tidal bore is a peculiar nature phenomenon which is caused by the lunar and solar gravitation. Based on the physical characters of tidal bores, in this paper we propose a novel method to model and render this phenomenon, especially the tidal waves in Qiantang estuary. According to Boltzmann equation for tidal waves, we solve it with the novel triangle mesh of kinectic flux vector splitting (KFVS)...
