A colour‐naming model was developed to categorize volumes for each of the 11 basic names in CIELAB colour space. This was tested with three different sets of data for two languages (English and Mandarin), derived from extensive colour categorization experiments. The performance of the model in predicting colour names was satisfactory, with an average prediction error of 8.3%. © 2001 John Wiley & Sons, Inc. Col Res Appl, 26, 270–277, 2001 相似文献

This tutorial examines how people of various cultures classify different colors as belonging together under common color names. This is addressed by examining Berlin and Kay's (1969) hierarchical classification scheme. Special attention is paid to the additional five (derived) color terms (i.e., brown, purple, pink, orange, and gray) that must be added to Herings' six primaries (i.e., white, black, red, green, yellow, blue) to constitute Berlin and Kay's basic color terms. © 2001 John Wiley & Sons, Inc.

Gamma Ray Array Detector(GRAD) is one of external target facility subsystems in the Cooling Storage Ring on the Heavy Ion Research Facility at Lanzhou(HIRFL-CSR).The trigger subsystem of GRAD is required to make a fast L1 trigger decision with a fixed latency for the data acquisition.Because the hit signals from the detector are asynchronous with the local clock of the trigger system,a nondeterministic latency(the value changes between zero and one clock period) is generated when the synchronous receivers of the conventional trigger system process the hit signals.In this paper,an improved trigger logic based on a field-programmable gate array is developed,and comprised of zero-delay broadening circuits as receivers and an improved adding circuit designed for the new receivers.Software simulation and experimental measurement have been conducted.Comparison with the conventional trigger logic,the improved trigger logic has the advantage of eliminating the nondeterministic latency and reducing the total processing latency. 相似文献

The naming of manipulable objects in older and younger adults was evaluated across auditory, visual, and multisensory conditions. Older adults were less accurate and slower in naming across conditions, and all subjects were more impaired and slower to name action sounds than pictures or audiovisual combinations. Moreover, there was a sensory by age group interaction, revealing lower accuracy and increased latencies in auditory naming for older adults unrelated to hearing insensitivity but modest improvement to multisensory cues. These findings support age-related deficits in object action naming and suggest that auditory confrontation naming may be more sensitive than visual naming.

In wireless sensor networks, sensor nodes are usually battery-operated computing and sensing devices, hence operations are limited by the initially equipped batteries, which are hard to be recharged or replaced. In this sense, saving energy consumption becomes significant. As most energy waste is from the always-on wireless interface, S-MAC is suggested to reduce energy consumption by introducing periodic listen/sleep scheme. However, when designing the listening time, S-MAC fails to consider the traffic distribution factor. In this article, an optimization for this scheme is proposed based on the distribution model. Evaluations show that the optimized S-MAC achieves considerable improvement in energy and latency. 相似文献

在已优选出来的最佳条件下,进行不同工艺路线下制取红麻全秆ASCMP的研究。结果表明料片水洗再汽蒸,然后预处理,再经常压二道磨浆,所得浆料在实验室抄造出的新闻纸,各项指标均达到或超过国家A级标准。通过PFI磨研究表明红麻ASCMP的适宜磨浆程度为磨至55~60°SR。采用SEM观察到了浆料中潜态的存在。消潜可在60℃下进行。用差热分析仪测定了磨木本素的玻璃化转变温度(Tg),由于木素被磺化,Tg下降了3.67℃。 相似文献
