In spite of great improvements in early diagnosis and interventions, most children diagnosed with autism spectrum disorders
(ASD) are unlikely to live independently when they reach adulthood. We have been conducting research on novel computer-based
interventions with the goal of promoting social skills. Working with 26 children with ASD, their teachers, and other stakeholders,
we have iteratively developed a set of activities based on applications that run on multitouch tablets. Our observations suggest
these activities increased pro-social behaviors such as collaboration and coordination, augmented appreciation for social
activities, and provided children with novel forms of expression. 相似文献

双目视觉系统在风洞伞摆角测量中的研究与应用 总被引:1,自引:0,他引:1
伞系统是飞行器的重要组成部分,其摆角参数是系统安全性的重要指标之一;针对目前风洞试验中伞摆角难以测量的问题,提出了一种基于双目视觉系统的试验方法,该系统主要由两部CCD相机、图像采集卡和控制计算机组成,通过立体视觉标定和数字图像处理技术解算出空间特征标记的三维坐标,根据坐标的空间几何关系计算出伞摆角参数;试验结果表明该方法应用成功,能够同时获取伞运动过程中投影在正交平面上的竖直和水平摆角,且具有系统组成简单、通用性强的优点,有较高的应用价值。 相似文献

We present a process to automatically generate three-dimensional mesh representations of the complex, arborized cell membrane surface of cortical neurons (the principal information processing cells of the brain) from nonuniform morphological measurements. Starting from manually sampled morphological points (3D points and diameters) from neurons in a brain slice preparation, we construct a polygonal mesh representation that realistically represents the continuous membrane surface, closely matching the original experimental data. A mapping between the original morphological points and the newly generated mesh enables simulations of electrophysiolgical activity to be visualized on this new membrane representation. We compare the new mesh representation with the state of the art and present a series of use cases and applications of this technique to visualize simulations of single neurons and networks of multiple neurons. 相似文献

The purpose of this article is to present an evolutionary model of the enablers and inhibitors affecting the implementation and sustainability of continuous improvement. With this aim, a qualitative study using the grounded theory was carried out. Interviews were conducted with managers responsible for continuous improvement in first‐tier suppliers in the automotive sector. As a result, two existing lines of research in the continuous improvement literature are synthesized: on one hand, the literature concerning the enablers and barriers associated with continuous improvement sustainability; and on the other, the literature concerning the evolutionary model. © 2011 Wiley Periodicals, Inc. 相似文献

In this paper, a new approximation to off-line signature verification is proposed based on two-class classifiers using an
expert decisions ensemble. Different methods to extract sets of local and a global features from the target sample are detailed.
Also a normalization by confidence voting method is used in order to decrease the final equal error rate (EER). Each set of
features is processed by a single expert, and on the other approach proposed, the decisions of the individual classifiers
are combined using weighted votes. Experimental results are given using a subcorpus of the large MCYT signature database for
random and skilled forgeries. The results show that the weighted combination outperforms the individual classifiers significantly.
The best EER obtained were 6.3 % in the case of skilled forgeries and 2.31 % in the case of random forgeries. 相似文献

This paper is concerned with the neutral‐delay‐dependent and discrete‐delay‐dependent stability for uncertain neutral systems with mixed delays and norm‐bounded uncertainties. Through constructing a new augmented Lyapunov‐Krasovskii functional and proving its positive definiteness, introducing some slack matrices and using integral inequality, the improved delay‐dependent stability criteria are derived in terms of linear matrix inequalities. Numerical examples are given to illustrate the significant improvement on the conservatism of the delay bound over some existing results.
