Polarization Phase-Based Method For Material Classification In Computer Vision

A robust and accurate polarization phase-based technique for material classification is presented. The novelty of this technique is three-fold in (i) its theoretical development, (ii) application, and, (iii) experimental implementation. The concept of phase of polarization of a light wave is introduced to computer vision for discrimination between materials according to their intrinsic electrical conductivity, such as distinguishing conducting metals, and poorly conducting dielectrics. Previous work has used intensity, color and polarization component ratios. This new method is based on the physical principle that metals retard orthogonal components of light upon reflection while dielectrics do not. This method has significant complementary advantages with respect to existing techniques, is computationally efficient, and can be easily implemented with existing imaging technology. Experiments for real circuit board inspection, nonconductive and conductive glass, and, outdoor object recognition have been performed to demonstrate its accuracy and potential capabilities.

平凉电厂300MW机组机炉协调控制系统及设备的优化改进

火电机组热控自动化水平的高低,直接反映着企业的安全生产和技术经济水平;同时为满足电网资源优化配置的需要,机组AGC功能的投运也势在必行。作为AGC投运基础的CCS能长期稳定的运行不但能够实现机组的最优控制,提高机组的发电效率而且可以降低运行人员的劳动强度。因此对新投产的机组在运行期间不断对CCS系统及各子系统逻辑组态进行优化完善,对CCS系统测量装置和执行机构进行调整改进,对各系统反复进行扰动试验完全可以使CCS系统长周期稳定投运,同时提高机组运行的可靠性和稳定性。重点介绍平凉电厂300MW机组CCS系统及设备的优化改进。

Capturing Attention When Attention "Blinks".

Four experiments addressed the question of whether attention may be captured when the visual system is in the midst of an attentional blink (AB). Participants identified 2 target letters embedded among distractor letters in a rapid serial visual presentation sequence. In some trials, a square frame was inserted between the targets; as the only geometric object in the sequence, it constituted a singleton. Capture effects obtained when the AB was most severe and when it was over were compared. There were 3 main results. First, capture occurred even when the AB was crippling, suggesting that a singleton exogenously engaged attention even when processing of a previous target was continuing apace. Second, when the singleton contained the key target feature, capture effects were clearly manifest. Third, even when the singleton did not possess the key target feature, it still succeeded in capturing attention, although the effects were both feeble and fleeting.
