一种新的Web数据模型-EOEM

随着XML的普及，开发具有同时查询XML文档和HTML文档能力的新一代Web查询语言已是当务之急．但现有的Web数据模型存在种种局限．本文提出了一种新的Web数据模型，能够同时支持HTML和XML等半结构化文档的查询．

Periodic event‐triggered observation and control for nonlinear Lipschitz systems using impulsive observers

In this paper, we investigate the observation and stabilization problems for a class of nonlinear Lipschitz systems, subject to network constraints, and partial state knowledge. In order to address these problems, an impulsive observer is designed, making use of the event‐triggered technique in order to diminish the network communications. Sufficient conditions are given to ensure a milder version of the separation principle for these systems, controlled via an event‐triggered controller. The proposed observer ensures practical state estimation, while the corresponding dynamic controller ensures practical stabilization. The sampling and the data transmission are carried out asynchronously. The dynamic controller is tested in simulation on a flexible joint. Copyright © 2017 John Wiley & Sons, Ltd.     

Measurements of the behavioral effects of albino mutation in mice (Mus musculus): Comparisons of coisogenic inbred and hybrid lines.

The effects of the albino gene on mouse behavior were examined, particularly its possible interactions with nonallelic genes (epistasis). More generally, the possible effects of genetic background (inbreeding depression or hybrid vigor) on the effects of the mutation were also considered. Tasks requiring either predominantly motor or predominantly cognitive capacity were studied for coisogenic albino and pigmented mice from either an inbred strain (C57BL/6 c/c vs C57BL/6 +/c) or an F? heterozygous generation (F? c/c vs F? +/c) from a BALB/c?×?C57BL/6 +/c cross. Results show a clear albino gene effect in the 2 lines and provide further evidence that the gene is the effective factor. There was no significant interaction between the mutation and the genotypic group (C57BL/6 or F?), which indicates that the effects of the mutation act approximately in an additive fashion between loci in these groups.

基于深度残差网络和GRU的SqueezeNet模型的交通路标识别

Existing traffic road sign recognition methods are all based on convolutional neural networks. As the number of the model network layers increases, the recognition accuracy will also be improved, but there are still some problems such as the reduction of efficiency and the increase of the number of parameters. Therefore, an improved SqueezeNet model combining deep residual network with GRU neural network (SqueezeNet IR GRU) is proposed. In order to enhance the learning efficiency, ELU function is used as the activation function. To avoid the disappearance of gradients when the network layer is too deep, a deep residual network is introduced to guarantee the stability of the model, GRU neural network that can memorize the important past features is utilized. Experiments were performed on the Cafir 10 and GTSRB datasets, and their recognition accuracy rates are above 99.13% and 88.25%respectively. The experimental results show that the SqueezeNet IR GRU model not only reduces the parameter amount greatly, but also its convergence, stability and recall rate are all much better than others.
