Deep convolutional neural networks (CNNs) have been successfully applied to a wide variety of problems in computer vision, including salient object detection. To detect and segment salient objects accurately, it is necessary to extract and combine high-level semantic features with low-levelfine details simultaneously. This happens to be a challenge for CNNs as repeated subsampling operations such...
Deep convolutional neural networks (CNNs) have delivered superior performance in many computer vision tasks. In this paper, we propose a novel deep fully convolutional network model for accurate salient object detection. The key contribution of this work is to learn deep uncertain convolutional features (UCF), which encourage the robustness and accuracy of saliency detection. We achieve this via introducing...
Fully convolutional neural networks (FCNs) have shown outstanding performance in many dense labeling problems. One key pillar of these successes is mining relevant information from features in convolutional layers. However, how to better aggregate multi-level convolutional feature maps for salient object detection is underexplored. In this work, we present Amulet, a generic aggregating multi-level...
In the study of controllability of complex networks, there are two core issues: the minimal number of inputs and the minimal number of controlled nodes needed to achieve full control. In this paper, we pay attention to find the optimal minimum driver nodes set with more stronger control ability by using the methods arising from graph theory and matrix theory. Firstly, we determine the minimum number...
Highly mono-disperse carbon spheres (CSs) with a tunable diameter of 300–4000 nm are shown to be successfully synthesised using sugar-rich wastewater as carbon sources and polyacrylamide (PAM) as a size-controlling agent. The effects of PAM and pH on the morphology and size were also investigated. Experimental results showed that PAM acted as a size-directing agent which directs the self-assembly...
In this paper, a new tri-band antenna with characteristic of miniaturization and low profile is proposed. The size is less than 45mm∗45mm∗9mm. This compact antenna is working at B3 L and S frequencies of Compass Navigation Satellite System (CNSS). The tri-band antenna is obtained with two microstrip patch antennas and a quadruple inverted-F antenna (QIFA) which is inserted in the two layers of substrates...
Periodic nanostructures spaced by half of the wavelength applied for nanometrology can be obtained by laser-focused atomic deposition. Experimental result with standing wave light mask is presented, showing a periodicity of 213 ± 0.1nm, a height of 4nm and a feature width of 64 ± 6nm. To further minimize the feature width and enhance the peak-to-valley contrast of the deposited lines, the effects...
A pair of degenerate primers was designed according to the conservative regions at the 3' terminus of the floral meristem identity genes (LEAFY). A 361 bp cDNA fragment of LEAFY homologous gene (PcBLFY) coding for 120 amino acid residues was amplified via RT-PCR from flower buds of male, female and hermaphrodite plant of Pistacia chinensis Bunge respectively. Furthermore, 989 bp genomic fragment of...
According to the land use data of urban areas of coal cities in China, 35 coal cities were selected and evaluated on intensive land use level through Analytic Hierarchy Process. By comparison of sub-item data and total data of evaluation result, the conclusion were drawn as follows: intensive land use level of the coal city is roughly positively correlated with its economic development. Besides, it...
Jining City is one typical overlapped area of coal mining and agricultural production in China. As a result, many prime farmland has been destroyed by mining subsidence. This paper adopted location entropy method to evaluate agricultural production status of Jining city in Shandong province and the whole country. On the basis of mining subsidence prediction to the end of Year 2020 and Year 2050, mathematic...
The threshold of a Brillouin fiber ring laser is investigated theoretically and experimentally. It is revealed that the resonance threshold is four times larger than the threshold of stimulated Brillouin scattering for the ring laser. The experimental results are well agreed with the theoretical emulation.
A novel scheme for tunable optical pulse generation based on fiber sagnac loop was proposed and studied. The key parameters of the optical pulse were analyzed and testified by experiments. The repetition rate of optical pulse is twice the frequency of external square wave modulation signal and can be tuned directly by varying modulation frequency. The maximal peak value can be achieved when the peak-peak...
