Design and Implementation of Piano Playing Automatic Scoring System Based on BP Algorithm [PDF]
随着人们物质生活水平的不断提高,人们对精神生活的质量要求越来越高,钢琴学习也受到越来越多人的追捧。采用计算机技术对钢琴演奏技术进行自动评价,可以减轻钢琴学习负担,提高钢琴学习效果。 钢琴音乐的评价特征因素众多,评价方法模糊。根据钢琴音乐和计算机处理的特点,以及钢琴乐音自动评价的需求,选取短时平均幅度、短时平均过零率和短时平均幅度差三个钢琴乐音特征来对钢琴音乐进行评价。基于BP算法信息处理能力强,不确定性信息处理能力强等特点,采用BP算法来实现对钢琴音乐的自动评价 ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Using incentive payments to promote human–carnivore coexistence
Abstract For many large carnivores, minimizing the financial burden they impose on local people is critical to their conservation. Incentive‐based programs that provide people with financial benefits for taking pro‐conservation actions or achieving conservation goals are a promising tool for promoting human–carnivore coexistence. Although the number of

变压器油中溶解气体在线监测是对油浸式变压器绝缘状况进行实时监测的有效技术手段。对油中溶解气体在线监测装置进行运行质量评价,对装置选型、供应商评价和保障变压器运行可靠性具有重要意义。现有的变电在线监测装置运行质量评价研究存在数据规模小和评价指标有限等问题。为提高评价水平,文中统计分析了大型数据集中在线监测装置的厂家分布、运行年限分布、数据质量等重要信息,然后建立了油中溶解气体在线监测装置运行质量的模糊层次综合评价模型;最后对数据集进行评价结果分析统计,证明了该评价体系反映各厂家监测装置实际应用情况的准确性。

On the Evaluation Mechanism of EU Risk Decision-making [PDF]
风险规制是21世纪行政法学较为前沿的研究课题。风险规制一般包括风险评估、风险管理以及风险交流三方面内容。本文所研究的欧盟风险决策的评价机制,属于风险评估事后层面的范畴。鉴于欧盟在2015年5月19日颁布的《更好规制指引》,该指引开创性的将评价机制作为风险决策过程中独立的分析工具,正式建立其统一、规范的评价机制。本文通过对欧盟委员会相关文件报告的梳理分析,从评价机制的演变过程、法律框架、组织架构、运行程序以及委员会下属各司具体评价实践情况等方面,加深对欧盟风险决策评价机制的认识 ...

How Do I Measure up? Social Influence and L2 Motivation in the Algorithmic Age
ABSTRACT Comparative thinking is a fundamental human drive and a hallmark of contemporary life. For social action, such as the learning and use of additional languages, a target for appraisal (an L2 attribute) is evaluated in relation to a comparison standard (an appraiser's standpoint).
