从设计符号学的角度看现代戒指设计     

李全恒  李燕明 《广东轻工职业技术学院学报》2011,(4):65-68

在信息化、全球经济一体化时代,设计符号语言得到越来越多的重视。本文运用设计符号学的一些原理来分析现代戒指设计,从消费者对戒指的体验传达出整体感官的符号信息,展开了全方位探索性的研究。希望设计师在对不同感受的调动中,能把它们放在一起考虑,挖掘出原本不很明显的设计源泉,设计出更为理想的作品。  相似文献   

终端滑模控制器设计在永磁同步电动机中的应用     

马新  平静水 《通化师范学院学报》2011,32(10):11-13

文中考虑了一类永磁同步电动机的终端滑模控制器设计问题.在控制器设计中利用中继切换控制使系统在给定的当前控制律的作用下运行到某一特定状态（或某一特定区域）后,控制律被切换到有限时间收敛的终端滑模控制器,使得系统在有限时间内达到平衡状态.终端滑模控制器的设计保证了闭环系统所有信号的有界性和平衡点的全局稳定性,以及系统在有限时间内精确地跟踪给定的参考信号.最后,通过一个数值仿真验证了所提算法的正确有效性.  相似文献   

论合唱指挥手势之视觉艺术     

房思钊 《山东教育学院学报》2011,26(2):120-123

指挥的职责是带领合唱队去完成合唱作品所赋予的使命。合唱指挥与队员的交流主要是通过视觉信息传递的,指挥把内心的语言和情感转化为视觉信息传达给队员,从而形成了指挥的视觉行为,即指挥手势。指挥手势的优劣不仅直接影响到作品的质量,还对听众在艺术鉴赏与艺术评价上形成导向,重视指挥的手势并视其为合唱整体中不可分割的重要部分,对于合唱指挥爱好者来说至关重要。本文从指挥的任务、指挥的功能、指挥的意识和表现形态为前提,结合力学原理和美学原理,浅论构成指挥手势的要素——点和线以及获点位置、获点角度、线的差异等对合唱指挥视觉艺术的影响。  相似文献

The integration of information in a digital,multi-modal learning environment     

《Learning and Instruction》2019

The aim of the reported eye-tracking study was to investigate whether learners integrate information presented on several pages within a digital learning environment and whether the underlying processes differ between a purely text-based and a multi-modal digital learning environment. Participants (N = 97) learned about the development of tornados. Picture presentation (yes vs. no) and presentation of inconsistent information between pages (yes vs. no) was varied between-subjects. Results showed that inconsistent information led to more intense gaze behavior. This indicates that learners re-activated information presented on previous pages to integrate it with the actual information, enabling them to detect the inconsistencies. Furthermore, the data pattern for text-related gaze behavior was not influenced by picture presentation, indicating that cognitive processes in purely text based or multi-modal learning environments are much the same. Comprehension outcomes did not differ between groups. The implications of these results are discussed.  相似文献   

Tensiomyographical responses to accelerometer loads in female collegiate basketball players     

Kyle D. Peterson  Gabriela T. Quiggle 《Journal of sports sciences》2017,35(23):2334-2341

The purpose of the present study was to characterise the relationship between relative versus absolute internal and external loads in collegiate basketball players throughout the course of a season. Five Division I basketball players wore triaxial accelerometers throughout the 2015–2016 season and were tensiomyographically assessed weekly. One-way repeated-measure analysis of variance (RM ANOVA) with least-significant-difference (LSD) pairwise comparisons was used to determine which absolute weekly loads were different across the season. Cohen’s d was used to supplement the determination of meaningful relative load changes. Overall RM ANOVA models suggest absolute external load differences occurred (PlayerLoad? F = 17.63; IMA? F = 31.63). Two-way RM ANOVA models revealed main effect differences were revealed between muscle groups for Tc (F = 9.11) and Dm (F = 3.25). Meaningful relative load changes between weeks were observed for both external and internal. The present study observed that tensiomyography utilised as a tool to monitor internal load may be more suitable for detecting fatigue from relative external load changes versus absolute load attained. Limiting weekly training volume changes to ≤10% may maintain appropriate adaptation. Mediolateral plane IMA? and adductor longus muscle group may be pertinent metrics when monitoring female collegiate basketball athletes.  相似文献
