基于“微平台”的高校思想政治理论课程开放式教学模式探究

长期以来,存在高校思想政治理论课教学效果差的问题,根本原因在于传统课堂教学具有局限性。以"微平台"为基础,构建思想政治理论课互动教学模式,能够有效促进师生互动和提高学生自主学习的积极性,强化学生自主学习意识,提高学习效果。在"微平台"上构建教学系统,整合教学内容,灵活运用教学手段,改革考核体系,是构建高校思想政治理论课开放教学模式的基本策略。     

智能点阵电子显示屏控制系统设计

该智能型点阵电子显示屏基于串并转换动态扫描技术,以微控制器为核心,辅以必要外围电路设计而成。系统主要由单片机控制、电子屏驱动显示、亮度调节、时钟定时、语音提示和键控液晶输出更新等模块组成。用字模软件生成字符代码存入单片机系统,通过相应的程序控制,利用串行输出方式将数据送入显示屏。显示电路进行串并转换后将数据送给各列,同时译码电路进行行扫描驱动,如此逐行扫描循环实现字符显示。通过控制LED点亮时间,实现亮度连续可调,通过时钟和温度模块实现实时温度时间显示。它实现了多机通信,主从机同时工作,实现主站控制多个地方的点阵显示。     

乙醇酸络合剂电镀Ni-W合金工艺探究

电镀Ni-W合金常使用柠檬酸或其盐为络合剂.文中采用极少应用的乙醇酸络合剂制备了Ni-W合金镀层,研究了镀液组成和操作条件对镀层组成及显微硬度的影响.结果表明：钨含量对镀层显微硬度起决定作用,而镀液中Na2WO4浓度和电流密度会显著影响镀层中的钨含量,进而影响镀层的显微硬度,镀层的显微硬度最高可达615HV.通过正交实验得出适宜工艺条件为：NiSO4.6H2O12g/L,Na2WO4.2H2O 48g/L,C2H4O3.2 H2O 60g/L,pH6.5,镀液温度70℃,电流密度1.8A/dm2.     

高职院校《审计实务》课程建设的构建与实施

《审计实务》是会计专业的核心课程,如何突破传统学科体系下的教学模式,体现高职教育所倡导的职业能力的培养与工作岗位的无缝对接,这是高职院校专业教师进行教改的目的。但前瞻性的研究专业和课程的发展趋向,则是教改的实质所在。     

Fair and Explainable Depression Detection in Social Media

Detection at an early stage is vital for the diagnosis of the majority of critical illnesses and is the same for identifying people suffering from depression. Nowadays, a number of researches have been done successfully to identify depressed persons based on their social media postings. However, an unexpected bias has been observed in these studies, which can be due to various factors like unequal data distribution. In this paper, the imbalance found in terms of participation in the various age groups and demographics is normalized using the one-shot decision approach. Further, we present an ensemble model combining SVM and KNN with the intrinsic explainability in conjunction with noisy label correction approaches, offering an innovative solution to the problem of distinguishing between depression symptoms and suicidal ideas. We achieved a final classification accuracy of 98.05%, with the proposed ensemble model ensuring that the data classification is not biased in any manner.
