Gaoya dianqi, 2017 以高压开关柜为研究对象,提出了一种基于正态云模型和D-S证据理论的分层评估算法。通过对影响开关柜运行状态的指标进行聚类分层,运用正态云模型确定各指标与各评价等级的关联度,并利用改进的模糊算法进行第1层评估,在此基础上运用D-S证据理论对开关柜整体运行状态进行评估。采用KYN28A-12型号某开关柜的一次检测数据为例,通过实例验证证明了评估算法的有效性。该评估模型结构清晰,评价指标易于得到,为开关柜状态评估提供了一种新思路。

International Journal of Applied Linguistics, EarlyView.ABSTRACT Many existing rubrics for L2 argumentative writing prioritize form‐based linguistic accuracy and complexity while insufficiently addressing substantive argumentative rigor and effectiveness. This limitation is further complicated by cross‐cultural variation in rhetorical conventions and educational practices, which challenge the direct ...

Haiyang gongcheng zhuangbei yu jishu, 2017 近年来海底管道由于腐蚀缺陷造成失效的事件有增多的趋势。为了评估在管道发生腐蚀后失效的风险性，对DNV-RP-F101的腐蚀管道强度评估方法进行研究，通过算例对影响强度评估的关键因素进行了敏感性分析，并对DNV-RP-F101和DNV-OS-F101的关系进行了探讨。结果表明，影响强度评估结果的三个主要因素中，缺陷检测数据误差对评估结果影响最大。当满足一定条件时，屈强比对评估结果的影响可忽略。

Dianci bileiqi, 2015 在雷击风险评估中,考虑到周围建筑物对评估对象截收面积的影响而引入了位置因子,但是由于周围建筑物的高低、远近等的不同,对评估对象截收面积的影响差别很大,根据现行雷击风险评估标准中给出的位置因子的取值,为典型经验值,导致了计算结果缺乏针对性,误差较大。针对以上问题,本文通过公式推导得出了位置因子的精细化计算模型,并通过对常见建筑物进行参数取样分析,探索式的引出了位置因子和评估对象高度的关系。发现当评估对象周边环境一定时,位置因子跟评估对象自身的尺寸参数息息相关,其中与评估对象的高度呈指数函数关系。

L2 Chinese Grammatical Acquisition and Processing: A Substantive and Methodological Review
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study presents a systematic review of 92 empirical studies on Chinese as a second language (CSL) in grammatical processing and development, synthesizing their substantive foci and methodological characteristics. The results reveal consistent scholarly attention to cross‐linguistic topics, with less focus on features that are distinctively

Finetuning Pre‐Trained Language Models for Automatic Assessment of English‐Chinese Interpreting
International Journal of Applied Linguistics, EarlyView.ABSTRACT Recent years have seen growing interest in leveraging pre‐trained language models (PLMs) for automatic assessment of spoken‐language performance. Contributing to this emerging line of work, the present study offers the first attempt to finetune two PLMs, GTE‐multilingual and mmBERT, for assessing English‐Chinese interpreting, using over 1700 ...

野生动物学报, 2015 动物福利科学一直强调关注个体动物的主观感受,科学评估动物的主观感受在有效提升动物福利状态、改进动物管理方面均具有重要意义。与通过行为数据及生理数据评估动物感受的定量方法相比,定性评估法具有耗时短、实时评估、便于多机构同步收集数据等多项优势,在动物园等圈养野生动物机构中具有重要的应用价值。用于定性评估圈养野生动物主观感受的现有方法包括:1)以动物的情绪状态特征和(或)行为特征为评估项的定性评估法; 2)基于动物自身的行为选择评估其主观感受的新方法——认知偏差法。本文也讨论了农场动物 ...

AI foundation models in plant biology
New Phytologist, EarlyView.Foundation models decode genomes, engineer proteins, phenotype crops, and drive AI agents across plant biology. This figure was created in BioRender (BioRender.com/xcmmkel). Summary Rapid technological progress has enabled plant biologists to accumulate unprecedented volumes of multi‐scale, multi‐modal data, yet this abundance of data has intensified ...

Gaoya dianqi, 2016 为了对断路器操动机构的分、合闸弹簧（简称弹簧）储能状态进行评估,将模糊综合评判应用到高压断路器的弹簧状态评估中。选取反映断路器弹簧储能状态的典型特征参量,建立评判因素集;根据断路器弹簧的实际状态情况,建立评判等级集;采用专家估计法与层次分析法,建立评判的权重集;构建隶属函数描述评估因素与状态等级间的模糊关系,确定模糊算子及结果处理方法,进而完成整个模型用以对断路器弹簧状态进行综合评估。LW25-126型断路器上的实例验证表明,该模型可以客观有效地评估高压断路器弹簧的储能状态。
