Suburban areas are the transitional zone between urban and rural areas, serving as key for addressing issues related to regional sustainable development. In this study, 294 prefecture-level cities in China were selected research objects. The spatial heterogeneity of social, economic, natural characteristics, well vitality realization suburbs China, was quantitatively analyzed at a national scale, impact socio-economic factors on suburban discussed. results show that has large with 431 km2...
Nature-based Solutions (NbS) is a concept aims to address challenges related human well-being, including health, socio-economic development, and ecological security on both national global scales. This was proposed against the backdrop of climate change, crises affecting humanity, threats sustainable development it has been increasingly recognized applied internationally over past decade. The principle NbS reciprocity between humans ecosystems, which completely in line with goals, systems,...
For long reach passive optical networks, double-sideband intensity modulation and direct detection can offer the advantages of low cost complexity. In this paper, we investigate a joint chromatic dispersion (CD) nonlinearity compensation technique using super-Nyquist image-induced aliasing Volterra series-based simplified nonlinear equalizer (SNE) in decision feedback manner. The SNE employed our experiments offers signal-to-noise ratio (SNR) performance comparable to conventional equalizers...
Lumen segmentation in intravascular optical coherence tomography (IVOCT) images is a fundamental work for more advanced plaque analysis, stent recognition, fractional flow reserve (FFR) assessment, and so on. However, the catheter, guide-wire, inadequate blood clearance, other factors will impact on accuracy of lumen segmentation. We present simple effective method automatic IVOCT based morphological features. use image enhancement, median filtering, binarization, closing operation to reduce...
We investigate temperature-dependent carrier transfer and efficiency droop on AlGaN-based deep ultraviolet light-emitting diodes. The Shockley-Read-Hall (SRH) recombination leakage are highly associated with the poor thermal stability. existence of Auger is identified by m-power method. A modified ABC model an additional term f(n) related to employed analyze evolution multiple mechanisms. SRH process strongly suppresses both at low currents. At high currents, latter two processes responsible...
Urban green infrastructure (GI) addresses human social development issues and challenges through urban space ecosystem services. However, the service functions of suburban cropland, especially regulating services cultural services, have been seriously underestimated. The distribution spaces cropland varies in different regions China, as well their potential methods. This article examines integrating into infrastructure, offering a perspective on nature-based solutions China. We divided China...
Cloud computing is currently becoming a popular topic in recent years. The innovative application of cloud emerges endlessly. In this paper, the platform architected by virtualization tool Proxmox VE and open source search engine Elasticsearch under concept virtualization. Based on platform, we explore feasibility advancement for storing searching spatio-temporal data. time period index imported as data records both location. experiment conducted using AIS data, which contains vessel motion...
We demonstrate the generation and detection of 170.49-Gb/s single-wavelength single-polarization IM/DD optical OFDM signals using Volterra-based two-step nonlinear equalization. A line rate 164.35-Gb/s is achieved after 2-km fiber transmission.
The recent research on individual identification of Internet Things (IoT) communication devices based radio frequency feature have promoted autonomous deployments wireless communication. But the signals is faced with defect high complexity, low degree integration and cost calculation. We propose a lightweight model. Convolutional neural memory network (CNMN), which reduces complexity model accelerates calculation speed, has been installed small computing to meet needs different scenarios. In...
Given the current radio frequency(RF) fingerprint identification methods based on deep learning, there is a problem of poor recognition performance in scene RF offset. This paper designs an Internet Things (IoT) devices system software defined radio(SDR) and transfer learning (TL) technology. The main advantage this to use universal peripheral (USRP) collect signals IoT identify preprocessed by SDR learning. can reduce data redundancy model complexity, has characteristics lightweight high...
As urbanization in China progresses, urban spatial development is transitioning from rapid expansion to more intensive and compact growth. This study examined the role of physical geography environmental factors shaping Guangdong-Hong Kong-Macao Greater Bay Area (GBA). Based on current natural conditions, we selected evaluation indices topography, hydrogeology, climatic disasters. These were used create a carrying capacity suitability system for land under constraints. Finally, potential...
A new inter-block precoding-based channel estimation (CE) scheme is proposed and experimentally demonstrated in an optical OFDM system with a superimposed pilot (SP). The precoding targets on eliminating the statistical mean of unknown data symbols, thereby improves performance SP-aided CE. We investigate impact that both matrix SP have performance, from which we obtain optimum value signal-to-pilot power ratio (SPR) as well block length. show through simulations experiments CE scheme,...
