综述了光纤光栅传感器近年来在工程结构健康监测、石油产业、电力行业、岩土工程、航空航天、采矿、爆破、交通及 医学等各个领域的应用情况。文章认为，限制光纤光栅传感器产业化和大规模应用的主要因素是缺乏统一的设计理论 和制作方法，这使得不同厂家生产的传感器规格存在差异。另外，由于复杂的生产技术和精细的生产过程使传感器生产 成本较高，而且能实际应用的光纤光栅传感器的解调产品并不多，且价格很高。根据上述分析，文中对该项技术未来的 发展方向提出了展望。(Overview of FBG sensors in recent years in various fields of engineering structural health monitoring, oil industry, power industry, geotechnical engineering, aerospace, mining, blasting, transportation and medical and other applications. Article that the main factor limiting FBG sensors and large-scale industrial applications is the lack of a unified design theory and production methods, which makes the sensors from different manufacturers specifications differ. In addition, due to the complexity of the production technology and sophisticated production process so that the sensor higher production costs, but also the practical application of fiber grating sensor product is not much, and the price is very high. Based on the above analysis, the article on the future direction of the technology raised the prospect.)

张量分解提取生物学特征，NFEA: Tensor Toolbox for Feature Extraction and Applications( Data in modern applications such as BCI based on EEG signals often contain multi-modes due to mechanism of data recording, e.g. signals recorded by multiple-sensors (electrodes), in multiple trials, epochs, for multiple subjects and with different tasks, conditions. Moreover, during processing and analysis, dimensionality of the data could be augmented due to expression of the data into sparse domain (time-frequency representation) by different transforms such as STFT, wavelets. That means data itself is naturally a tensor, and has multilinear structures. Standard approaches which analyze such data by considering them as vectors or matrices might be not suitable due to risk of losing the covariance information among various modes. To discover hidden multilinear structures, features within the data, the analysis tools should reflect the multi-dimensional structure of the data)
