Catalytic oxidation is an effective way to eliminate soot pollution emitted from diesel engines. However, the origination and specific location of active oxygen species are still unclear over noble metal catalysts because complex gas (oxygen)–solid (catalyst)–solid (reactant) reaction systems. Herein, we report high catalytic performance nanoflower-like hydrotalcite-derived CoAlO-supported Ag catalyst synthesized by a facile hydrothermal method for combustion. Our characterization results...
Deep face recognition has achieved great success due to large-scale training databases and rapidly developing loss functions. The existing algorithms devote realizing an ideal idea: minimizing the intra-class distance maximizing inter-class distance. However, they may neglect that there are also low quality images which should not be optimized in this strict way. Considering imperfection of databases, we propose objectives can a moderate way mitigate overfitting problem, further novel...

The macroporous nanostructures created by the improve soot-catalyst contact efficiency external surface catalysts. superficial Mn–Ce interaction can produce Mn4+ and oxygen vacancies Ce/Mn-NF catalysts through redox process Ce4+ + Mn3+ ↔ Ce3+, simultaneously generating active species. Moreover, our results demonstrate that adsorbed species...
In the field of face recognition, large-scale web-collected datasets are essential for learning discriminative representations, but they suffer from noisy identity labels, such as outliers and label flips. It is beneficial to automatically cleanse their noise improving recognition accuracy. Unfortunately, existing cleansing methods cannot accurately identify in wild. To solve this problem, we propose an effective automatic framework datasets, FaceGraph. Using two cascaded graph convolutional...

Reducing computational costs is an important issue for development of embedded systems. Binary-weight Neural Networks (BNNs), in which weights are binarized and activations quantized, employed to reduce various kinds applications. In this paper, a design methodology hardware architecture inference engines proposed handle modern BNNs with two operation modes. Multiply-Accumulate (MAC) operations can be simplified by replacing multiply bitwise operations. The method effectively the gate count...

Trajectory data uploaded by mobile devices is growing quickly. It represents the movement of an individual or a device based on longitude and latitude coordinates collected GPS. The location service has broad application prospect in real world. As traditional prediction models which are discrete state sequence cannot predict locations time, we propose Continuous Time Series Markov Model (CTS-MM) to solve this problem. method takes Gaussian Mixed (GMM) simulate posterior probability...
This paper proposed Air Entrainment Model (AEM) and Mass Transfer-Volumetric Heating Source model (MT-VHS). Then different physical models of tunnel, gas description combustion were used. CFD results compared with reduced scale experiments previous theories. The show that traditional numerical simulation on tunnel may cause asymmetrical temperature profile, because the pressure portal is always set to be constant. Expanded computational domain can avoid this unreasonable setting. Boussinesq...
