"算法与程序设计"和"智能机器人" 课程整合初探

作为高中信息技术选修课中的一门基础课,"算法与程序设计"课程体现了对学生信息素养提升的更新要求,而"智能机器人"则是高中通用技术学科里学生非常感兴趣的一门选修课.本文概述了这两门课程的教学中凸显的问题,进一步分析两门课程的区别和联系,总结出两门课程进行学科整合的可行性,并从几方面进行了优化整合实践,突破了这两门课程的教学瓶颈,改进教学效果,从而为提升学生信息素养起到推动作用.     

高职院校英语精读教师的综合素质

教师素质是加快教学改革,提高教学质量的关键。要提高高职院校英语精读教师的综合素质,需从政治,业务以及技能三方面入手。     

只不过是错觉——评《婚姻保卫战》

随着《婚姻保卫战》的热播,女权意识与男权传统这一经典的话题引起了社会的广泛关注和讨论,该剧对传统的女性和男性形象进行了时代新演绎,弘扬了女性追求自由、反叛夫权的独立意识。表面上看是女权突围男权的成功典范,实则在故事讲述中流露出对男权话语的心悦诚服,男女平等的虚浮美丽背后却只是错觉。     

平等对话：凸显主体地位的语文阅读教学策略

在语文阅读教学中,学生与文本（作者）、学生与学生、教师与学生、教师与文本几种类型的对话是交互进行的。为此,“对话式”的阅读教学,必须处理好以下三组关系：对对话的问题,必须兼顾文本内容与形式;对对话的生命,必须确保对话主体的平等;对对话的难点,必须正确处理文本的价值取向与学生独特体验的关系。要在语文阅读教学过程中,更加凸显学生在阅读教学中的主体地位,促进学生个性的发展。     

小学语文教学的人文精神

人文精神的缺失是我国基础教育存在的严重弊端。本文列举了小学语文教学人文教育缺失状况,提出在小学语文教学中进行人文精神的渗透,必须立足课堂、拓展课外;植根教材、走向生活;重视朗读、紧扣情感;尊重个性、注重体验。     

A highly alkaline-stable metal oxide@metal–organic framework composite for high-performance electrochemical energy storage

Most metal–organic frameworks (MOFs) hardly maintain their physical and chemical properties after exposure to alkaline aqueous solutions, thus precluding their use as potential electrode materials for electrochemical energy storage devices. Here, we present the design and synthesis of a highly alkaline-stable metal oxide@MOF composite, Co₃O₄ nanocube@Co-MOF (Co₃O₄@Co-MOF), via a controllable and facile one-pot hydrothermal method under highly alkaline conditions. The obtained composite possesses exceptional alkaline stability, retaining its original structure in 3.0 M KOH for at least 15 days. Benefitting from the exceptional alkaline stability, unique structure, and larger surface area, the Co₃O₄@Co-MOF composite shows a specific capacitance as high as 1020 F g⁻¹ at 0.5 A  g⁻¹ and a high cycling stability with only 3.3% decay after 5000 cycles at 5 A g⁻¹. The as-constructed solid-state flexible device exhibits a maximum energy density of 21.6 mWh cm⁻³.     

Challenges and opportunities facing game theory and control: an interview with Tamer Başar

The Control community has recently witnessed an almost exponentially growing interest in the application of game-theoretic concepts and tools in research on control, multi-agent systems, and networks. In an interview with NSR, Professor Tamer Başar, a member of the US National Academy of Engineering, Swanlund Endowed Chair and CAS Professor of Electrical and Computer Engineering, and Director of the Center for Advanced Study at the University of Illinois at Urbana-Champaign in the USA, former president of both the IEEE Control Systems Society and the American Automatic Control Council, and the founding president of the International Society of Dynamic Games, talked about the recently emerging role of game theory in control and networking research, how it broadens the territorial boundaries of control into disciplines outside engineering, and opportunities and challenges that lie ahead.     

Electro-mechanically controlled assembly of reconfigurable 3D mesostructures and electronic devices based on dielectric elastomer platforms

The manufacture of 3D mesostructures is receiving rapidly increasing attention, because of the fundamental significance and practical applications across wide-ranging areas. The recently developed approach of buckling-guided assembly allows deterministic formation of complex 3D mesostructures in a broad set of functional materials, with feature sizes spanning nanoscale to centimeter-scale. Previous studies mostly exploited mechanically controlled assembly platforms using elastomer substrates, which limits the capabilities to achieve on-demand local assembly, and to reshape assembled mesostructures into distinct 3D configurations. This work introduces a set of design concepts and assembly strategies to utilize dielectric elastomer actuators as powerful platforms for the electro-mechanically controlled 3D assembly. Capabilities of sequential, local loading with desired strain distributions allow access to precisely tailored 3D mesostructures that can be reshaped into distinct geometries, as demonstrated by experimental and theoretical studies of ∼30 examples. A reconfigurable inductive–capacitive radio-frequency circuit consisting of morphable 3D capacitors serves as an application example.
