A Systematic Scoping Review of Self‐Regulated Learning With AI in Language Education
International Journal of Applied Linguistics, EarlyView.ABSTRACT The rapid development of artificial intelligence (AI) technology has brought new opportunities for second/foreign language (L2) education while also raising concerns about the use of AI tools. This systematic scoping review provides a snapshot of the current state of research situated at the intersection of self‐regulated learning (SRL) and AI

Gaoya dianqi, 2015 文中针对直流断路器与柔性直流系统的保护配合进行分析,理论分析了保护配合可行的策略和方式,进而针对不同电压等级下的直流系统实例,结合断路器样机测试结果,利用PSCAD/EMTDC仿真软件分析了极间短路故障时保护配合对系统参数和断路器参数的要求。仿真结果表明,不同保护策略下对系统耐受能力和直流断路器开断性能要求不同,需要根据系统特点选择不同的保护策略。

Guangtongxin yanjiu, 2020 随着国家电网公司电力物联网战略的提出,电力物联网越来越引起人们的关注。文章针对电力物联网中的基站部署策略进行研究。不同于传统的不考虑用户行为的基站部署策略,文章提出了一种新的表征网络空间和业务聚集的聚集系数定义,并在此基础上对高能效基站部署策略进行研究。仿真结果表明,泊松簇叠加策略更适用于用户聚集程度较高的场景,其能效比其他方案低。泊松点过程策略网络能效高但只适用于聚集程度低的场景。

Gaoya dianqi, 2016 根据直流微电网的结构以及运行特点,分析了直流微电网中分布式发电单元和混合储能单元的控制策略。针对直流微电网中由于分布式发电单元输出功率的不稳定以及负载突变造成的直流母线电压波动问题,提出了一种基于直流微电源模块和混合储能模块的协同能量管理策略。该控制策略以直流母线电压为信号对混合储能模块的充放电模式进行控制。同时也搭建了含光伏微源单元和混合储能单元的仿真模型,通过MATLAB/Simulik仿真软件对混合储能的能流切换模式进行仿真 ...

大数据压缩策略是影响IoT时序数据存储系统性能的重要因素，而现有压缩策略缺乏针对NVM与IoT时序数据特性的优化机制。因此，提出了面向NVM的IoT时序数据多态协作压缩策略。首先，给出了IoT时序数据的组织结构。然后，针对IoT时序数据在一段时间内较稳定以及在用户态与内核态读写NVM适合的粒度差异较大的情况，设计了分层压缩策略。在用户态接收数据时，采用轻量级的数据压缩算法减少需存储的数据量，也减小了对IoT时序数据的存储效率的影响；针对IoT系统以查询和分析异常时序数据为主的特性，设计了深度压缩算法 ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how foreign language teachers’ beliefs about the medium of instruction and translanguaging evolve over time by revisiting three in‐service teachers twelve years after their initial interviews. Using a qualitative longitudinal design, the study traces how translanguaging was initially framed as pedagogically deficient but ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT While English‐medium instruction (EMI) and English for Academic Purposes (EAP) courses are designed to promote language and content learning, their prevailing English‐only approaches often undermine students’ learning motivation. Against this backdrop, translanguaging has gained recognition as an effective pedagogical practice to support ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Collaborative writing has attracted increasing attention in English as a Foreign Language (EFL) instruction due to its potential to enhance learners’ writing competence. However, few studies have examined the comparative effects of collaborative versus independent writing on EFL learners’ individual performance, especially in higher‐order ...

International Journal of Applied Linguistics, EarlyView.ABSTRACT Oral interaction plays a facilitative role in second language acquisition. While numerous studies have explored adult learners’ interactions, research that has examined young learners’ interactions, especially among Chinese as a second language learners (CSLs), is lacking. This study focused on CSLs and Chinese‐speaking students (CSSs) in Hong
