Growing muscle tissue in culture from animal stem cells to produce meat theoretically eliminates the need to sacrifice animals. So-called ＂cultured＂ or ＂synthetic＂ or ＂in vitro＂ meat could in theory be constructed with different characteristics and be produced faster and more efficiently than traditional meat. The technique to generate cultured muscle tissues from stem cells was described long ago, but has not yet been developed for the commercial production of cultured meat products. The technology is at an early stage and prerequisites of implementation include a reasonably high level of consumer acceptance, and the development of commercially-viable means of large scale production. Recent advancements in tissue culture techniques suggest that production may be economically feasible, provided it has physical properties in terms of colour, flavour, aroma, texture and palatability that are comparable to conventional meat. Although considerable progress has been made during recent years, important issues remain to be resolved, including the characterization of social and ethical constraints, the fine-tuning of culture conditions, and the development of culture media that are cost-effective and free of animal products. Consumer acceptance and confidence in in vitro produced cultured meat might be a significant impediment that hinders the marketing process.

合理地分析并准确计算台区可开放容量,能够优化配电系统的运行,提高线路利用率,保证台区配电变压器安全、经济、稳定运行。传统的可开放容量计算方法主要基于线路输电能力经验公式进行计算,未考虑高负荷运行台区的短时性及季节性,存在计算准确率和普适性低的问题。因此,提出一种基于局部加权周期趋势分解算法(STL)和季节性自回归滑动平均模型(SARIMA)与动态同时率(DSR)的台区可开放容量计算方法。该方法首先利用STL将历史台区负荷数据分解为趋势项、季节项和余项;其次,根据调整的历史台区负荷数据建立SARIMA台区负荷预测模型,预测未来台区负荷的变化及负荷峰值;同时,根据台区历史负荷数据建立台区DSR准则;最后,构建SARIMA‐DSR模型,合理调整可开放容量计算方法中的配置系数,实现台区的可开放容量的准确计算。

An acoustic emission （AE） linear location system was proposed, which employed fiber Bragg gratings （FBGs） as AE sensors. It was demonstrated that the FBG wavelength could be modulated as the static case when the grating length was much shorter than the AE wavelength. In addition, an improved AE location method based on the Gabor wavelet transform （WT） and threshold analysis was represented. The method was testified through AE linear location experiments based on a tunable narrow-band laser interrogation system using ultra-short FBG sensors as AE sensors. Results of the experiments showed that 86% of the linear location errors were less than 10mm.
