Building extraction based on remote sensing images has been widely used in many industries. However, state-of-the-art methods produce an incomplete segmentation of buildings owing to unstable multi-scale context aggregation and a lack consideration semantic boundaries, ultimately resulting large uncertainties predictions at building boundaries. In this study, efficient fine were explored, which demonstrated that the rational use edge features can significantly improve recognition...

To improve electromagnetic wave (EMW) absorption performance, a novel nano-laminated Dy3Si2C2 coating was successfully in situ coated on the surface of SiC whisker (SiCw/Dy3Si2C2) using molten salt approach. A labyrinthine three-dimensional (3D) net constructed by one-dimensional (1D) SiCw with two-dimensional (2D) layer thickness ~100 nm, which significantly improved EMW properties SiCw. Compared to pure minimum reflection loss (RLmin) value -10.64 dB and effective bandwidth (EAB) 1.04 GHz...

A novel nano-laminated GdB2C2 material was successfully synthesized using GdH2, B4C, and C via an in-situ solid state reaction approach for the first time. The formation mechanism of revealed based on microstructure phase evolution investigation. purity 96.4 wt. % obtained at a low temperature 1500 ℃, while near full pure can be over 1700 ℃. as-obtained presented excellent thermal stability high 2100 ℃ in Ar atmosphere due to stable frame work formed by covalent four-members eight-members...

Offshore aquaculture promotes the development of industry and brings huge economic benefits to fishermen, while seriously affecting near-coast environment. Accurate access range offshore farms at home abroad is great significance for marine disaster warning coastal management. Remote sensing a very effective means observing farms. segmentation technology more mature in high-resolution optical images. SAR images have advantage being available all day night. Using extract has become recent...

Extracting buildings from remote sensing imagery can serve many industries. Single-category building extraction, however, has been unable to meet the actual needs of sectors, such as disaster prevention and mitigation. In this study, we create a large-scale high-quality multispectral dataset (BFE-Set) for fine-grained extraction buildings. BFE-Set uses GaoFen-2 satellite data source divides into three categories according their structure types: steel reinforced concrete structure, masonry...

Earthquake disasters are marked by their unpredictability and potential for extreme destructiveness. Accurate information on building damage, captured in post-earthquake remote sensing images, is critical an effective post-disaster emergency response. The foundational features within these images essential the accurate extraction of damage data following seismic events. Presently, availability publicly accessible datasets tailored specifically to earthquake-damaged buildings limited,...

Flood disasters are frequent, sudden, and have significant chain effects, seriously damaging infrastructure. Remote sensing images provide a means for timely flood emergency monitoring. When floods occur, management agencies need to respond quickly assess the damage. However, manual evaluation takes amount of time; in current, commercial applications, post-disaster vector range is used directly overlay land cover data. On one hand, data not updated time, resulting misjudgment disaster...

The undulating terrain in mountainous and hilly regions results a greater variety complexity of shadows. Efficient methods for shadow detection reconstruction high-resolution remote sensing images are particularly important such areas. accurate masks is prerequisite reconstruction. By utilizing the features high hue low intensity areas, an initial spectral ratio constructed based on CIELCh color space model. Simple linear iterative clustering employed to perform superpixel segmentation...

Abstract. Landslide dams are caused when landslide materials block rivers. After the occurrence of large-scale landslides, it is necessary to conduct a investigation barrier lakes and rapid risk assessment. Remote sensing an important means achieve this goal. However, at present, remote only used for monitoring extraction hydrological parameters, without predicting potential hazard dam. The key parameters dam, such as dam height maximum volume, still need be obtained based on field...

The high-speed communication service in future mass transportation systems is a challenging target for the design of next generation protocols. Especially bullet trains are promising, but details real environments little known to us. In this paper, we address estimation quality (QoS) mobile environments, assuming radio link proprietor and using only commercially available network devices. Firstly, make definition invariant qualities trains, which not dependent on each measurement. Then...

Legacy applications are the huge existing IPv4-based network applications. It is a critical subject to maintain them availability during IPv6 transition period. However they could run properly neither in IPv6-only networks nor between IPv6/IPv4 heterogeneous networks. That has resulted limitation of widespread adoption IPv6. To deal with this problem, we propose novel framework called 4644 two new mechanisms (i.e. API Adapter and Address Control Protocol). In 4644, end users able seamlessly...

Qinghai Lake National Nature Reserve plays an important role in maintaining the ecological balance of Tibet Plateau. It is place for biodiversity protection. Several Institutes Chinese Academy Sciences, collaborated with Reserve, have carried out joint research area. With video cameras installed this region, a lot precious data rare animals been accumulated. Mobile Internet provides users ability to visit Network anywhere and anytime. necessary provide public way access these valuable...

Nature reserve is very important for natural environment and resources protection, scientific research, education advocacy, biodiversity, etc. A huge number of multimedia data, including digital pictures videos, are accumulated in nature reserves. With the rapid rise mobile Internet devices, it necessary reserves to provide public way access these valuable attractive data through Internet. In this paper, we implement such a system. We detail system architecture implementation. At end look...

Nowadays, Internet has become an indispensable part of our life.Smartphone important device to access Internet.Hundreds millions smartphones need a large number IP addresses.IPv6 instead IPv4 can meet the address requirement.IPv6 also many advantages compared IPv4.In China, IPv6 research and construction been carried out for years have yielded great deal fruits.While application is far from sufficient.Smartphone may be killer field IPv6.In this paper, we test functions on mainstream which...

With the rapid development of Internet, current Internet Protocol IPv4 cannot meet new requirements. Compared with IPv4, IPv6 has more advantages. Fruitful results have been borne in aspects protocol study and network construction China. On other hand, application popularization is far from sufficient. In recent years, mobile devices popularized very rapidly. More people use devices, including smartphones tablets, to surf online everywhere. If such a gigantic amount can access IPv6, it will...
