齐鲁文化创意产业发展和品牌打造刍论

当代齐鲁地域文化资源保护开发和文化品牌建设应积极顺应文化创意产业发展的大潮流,实现从单纯依赖物质、地理、名胜、生物资源的传统文化产业模式向偏重精神资源开发、文化创意、高科技的数字化文化创意产业模式转变。目前,不合理的人才结构、根深蒂固的传统文化观念、政府主导型的文化产业发展模式等因素正制约着山东文化创意产业的发展。所以,山东文化创意产业的发展必须首先解决文化自身的瓶颈问题,而充分利用网络传媒技术加大地域文化资源创意产业开发不仅是必要的,也是可行的。     

无线传感器网络节点的物理层设计

比较和分析了无线传感器网络节点物理层设计的各种无线通信技术、现有的成熟标准、重要的射频参数以及不同的处理器方案,对节点物理层设计的各个主要方面进行了较为全面的研究.介绍了无线传感器网络节点的一种实现,给出了相关的测试数据以及一种“单处理器双工作频率”的新节能策略.分析了符合传感器网络MAC算法中节点周期性侦听要求的节点寿命估算问题.指出无线传感器网络节点物理层设计的关键考虑因素为:RF启动时间(决定MAC协议可以实现的最佳节点睡眠时间比例和最小的退避时间颗粒)、RF载波频率和调制方式(决定射频收发功耗)以及处理器工作在2个频率的片上系统的总体功耗.     

Evaluating a technology supported interactive response system during the laboratory section of a histology course

Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper‐level histology course, the interactive application Learning Catalytics^TM, a cloud‐based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions “on‐the‐go,” engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five‐point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.

基于VB6.0的液压支架模型智能设计系统

传统液压支架产品的设计和应用随着液压支架应用范围的持续扩展,逐渐出现了滞后现象。因此,有必要结合液压支架的现实使用需求,开发一种新型液压支架设计平台。借助蓝光数字矿山地理信息平台,采用VB6.0编程语言实现了液压支架设计系统的参数化与标准化。在液压支架模型建立过程中,现有Delauany三角剖分方法可用于任意多边形的三角剖分。该软件缩短了开发周期,简化了设计流程,降低了设计成本,并提高了设计效率,从而有效增强了产品的市场竞争力。
