Research on Stochastic Resonance Based on RLGA and its Application to Underwater Acoustic Signal Detection [PDF]
, 2017 我国在水下通信领域方面正在持续地投入研究，其中一个方面是通信中信号的检测。信号经过水声信道后往往都会被来自船舶、海洋生物或者人为的大量噪声和海面折射反射、频率选择性衰弱引起的干扰淹没，变为微弱信号。而水声信号的检测技术不论在理论钻研还是实际工程甚至国防建设中都具有重要的意义和应用价值。因此，研究微弱信号的检测方法对水声通信的进步和发展很有必要。 一些传统的信号检测方法如匹配滤波、相干检测、时频分析等都采用抑制噪声的方法，往往都是在抑制噪声的同时，在频率结构或者时域幅值上也不同程度地损害了有用信号 ...

PBL教学法结合标准化病例教学模式在儿科临床实习教学中的应用效果研究
Zhongguo shiyan zhenduanxue, 2023 儿科临床实习教学是《儿科学》整个教学过程中的重要环节，是完成教学知识、能力、情感目标的重要阶段，是培养学生独立临床诊疗思维和增强医患沟通能力的重要途径。但是，由于儿科患者群体及疾病的特殊性，导致儿科临床实习常缺少典型病例及临床实践机会，带教老师多以传统的灌输式、观摩式教学为主，已实施的教学改革也多缺少标准统一化示教病例，并且少有结合学生互动教学模式，导致造成儿科临床实习课程教学目标达成度不高。

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, EarlyView.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.
