Study design News reports were crawled obtain scenario elements categorized into spreading stage or derivation stage. Finally, key nodes evolution process analyzed in combination with a corresponding emergency response assessment...

From a holistic view, this paper addresses perspective of coordinated development economy, society, and environment for regional sustainability assessment. Firstly, comprehensive indicator system co-evaluating the level economic, social, environmental subsystems is presented based on understanding sustainability. Then, index model focusing coordination among as well their established. Furthermore, an empirical study all provinces municipalities conducted by collecting panel data from 2004 to...

A combined in-mold decoration and microcellular injection molding (IMD/MIM) method by integrating (IMD) with (MIM) was proposed in this paper. To verify the effectiveness of IMD/MIM method, comparisons (IMD), conventional (CIM), simulations experiments were performed. The results show that compared MIM, film flattens bubbles have not been cooled turned to surface, thus improving surface quality parts. existence an asymmetrical temperature distribution along thickness sample, higher on side...

Microstructure evolution during the hot isostatic pressing (HIP) of continuous silicon carbide fiber-reinforced Ti (SiCf/Ti) composites has not been investigated. In this study, SiCf/Ti60 were prepared via HIP solidification method Ti60 precursor wires. The microstructure wires and was characterized using electron backscatter diffraction microscopy transmission techniques. results showed that deformation α-Ti mainly accomplished by basal <a> dislocations prismatic slip process. After...

Forecasting short-term traffic flow is a key issue in the field of Intelligent Traffic System (ITS). Most existing researches are oriented to urban road network, development forecasting technology provides good reference for port. However, complexity and uncertainty port determine that it necessary study methods pertinently. Based on K- Nearest Neighbor (KNN) algorithm, this paper forecasted flow, defined factors affecting port, such as working status operation instruction characteristics,...

Environmental conflicts have been a top global focus and issue for human’s sustainable development. China is confronted with serious situation rigid demand of ecological governance, in which the “Not In My Back Yard” (NIMBY) crisis outbreaks frequently. NIMBY has great impact on government management social stability. This study aims to analyze transformation path municipal solid waste incineration (MSWI) China. Considering environmental, economic influences, this seeks find methods...

As the impact factors of waste Not-In-My-Back Yard (NIMBY) crisis are complex, and scenario evolution path it is diverse. Once not handled properly, will bring adverse effects on construction NIMBY facilities, economic development social stability. Consequently, based ground theory, this paper takes in China from 2006 to 2019 as typical cases, through coding analysis, established. Furtherly, three key scenarios were obtained, namely, external situation (E), state (S), emergency management...

Nanochannel structures with a feature size deeply under the diffraction limit and high aspect ratio hold huge biomedical significance, which is especially challenging to be realized on hard brittle materials, such as silica, diamond, sapphire. By simultaneously depositing pulse energy surface inside sample, nanochannels smallest of 18 nm (∼1 / 30λ) more than 200 ratios are achieved mechanism can concluded assisting material ejection effect. Both experimental theoretical results prove that...

Speaker recognition is a kind of biometrics technology, which very popular and widely applied. To improve the effectiveness feature parameter, weighted extraction method proposed in this paper. It analyses each component LPCC finds out an average contribution sequence. Based on sequence, weighed by dimension to generate parameter. Finally, based VQ, speaker system characterized carried under MATLAB Environment. By experiments, shows better performance than traditional model.
