摘要：论文分析了目前传统的灯饰设计所存在的不足,提出了客户与设计师协同设计的可行方案,详细介绍了基于Web3D的灯饰协同设计关键技术,包括灯饰模型交互设计和同步互斥技术,开发出了一个以客户为主,以设计师为辅并基于Web3D技术的网上协同设计系统,并通过实验验证了系统的可行性。

摘要：针对传统特征提取主观性强、识别率不高,而现有卷积神经网络层数较多、规模过大、结构不够轻量化等问题,提出一种结合主成分分析(PCA)和卷积神经网络的人脸表情识别方法。使用主成分分析对数据集原始图片进行降维重构,去除与面部表情无关的冗余信息,将图像进行数据增强之后作为输入图像输入到改进神经网络模型进行识别。该网络在输入层加入一层非线性表示层,并在全连接层前采用全局平均池化保留局部信息,结构较为轻量,参数量少。在公开的数据集FER2013、JAFFE中进行实验,并且对实验结果进行分析。实验结果表明,该方法在FER2013和JAFFE数据集的准确率达到了69.07%和98.23%。所提方法有效地提高人脸识别的性能,为人脸表情识别领域改进识别率方向提供了一个思路。

摘要：Key techniques to improve the quality of developing Web-based engineering drawing CAI software are discussed and some experience in applying commercial tools for generating vector drawing, concise representation of 3D solids, real-time interactive animation, data management etc. is illustrated. A Web-based Engineering Drawing CAI software 'Solid Projection' has been implemented by using these techniques.

摘要：信息类专业的课程相对于高职高专生、成教生来说困难较大,特别是逻辑性强的课程如计算机电路、程序设计、网络技术等课程。极易造成学生厌课。模糊分级教学法则是分解课程难度,将整个一门课程分成模糊教学和进阶教学两个阶段。前一阶段进行概括式教学,构建内容主线;后一阶段进行强化式教学,深入内容细节。

摘要：针对目前智能窗户发展不够成熟以及产品成本过高的问题,在国内光纤以太网和云计算技术迅猛发展、无线局域网普及的背景下,开发了物联网智能窗户系统。设计采用arduino控制芯片以及各种传感器芯片组建智能窗户,并通过ESP8266WIFI芯片接入互联网;利用伪造序列号的方式完成TCP协议的NAT穿越,实现手机终端到智能窗户的点对点连接;通过云虚拟主机平台,实现对智能窗户的管理。该智能窗户系统具备实时监测,远程控制,智能安防等功能,满足了用户对智能生活的要求。

摘要：Techniques of Viewpoint-binding, interactive Viewpoint-animation interaction and their realization with VRML2 are illustrated

摘要：VRML offers powerful tool for generating 3D scene and realizing real time interactive animation on Web. This paper briefly introduces the related techniques of implementing interactive animation in Web 3D, focusing on how to use JavaScript to create Script node for extending VRML functions. This is very useful for virtual product design, product performance simulation, virtual assembly and remote education.

摘要：To avoid the shortcomings of many Web education systems that look like Web books, a true Web multimedia Engineering Graphics courseware is developed to explore the method and techniques of 2D animation with text, buttons, sounds and graphics merged together. For speeding up the transmission and download, data compression and interactive approach are introduced.

摘要：The way of reform and development of Engineering Drawing education is explored. Such activities have been carried out for 5 years, and great progress in the update of course contents, teaching methods and other related aspects is achieved. A series of textbooks, multimedia CD and established a Web site for Engineering Drawing course have been published. The efforts to realize an advanced contemporary teaching mode are being made. With the support of multimedia software and resources over Internet, students become the real main body of study, the teaching qualities are supervised and controlled throughout, and the students?imagination and ability of design and drawing are greatly enhanced. All reform is built on digital technology.
