Investigation of texture effect on visual colour difference evaluation

The texture effect on visual colour difference evaluation was investigated in this study. Five colour centers were selected and textured colour pairs were generated using scanned textile woven fabrics and colour‐mapping technique. The textured and solid colour pairs were then displayed on a characterized cathode ray tube (CRT) monitor for colour difference evaluation. The colour difference values for the pairs with texture patterns are equal to 5.0 CIELAB units in lightness direction. The texture level was represented by the half‐width of histogram, which is called texture strength in this study. High correlation was found between texture strength and visual colour difference for textured colour pairs, which indicates that an increasing of 10 units of texture strength in luminance would cause a decreasing of 0.25 units visual difference for the five colour centers. The ratio of visual difference between textured and solid colour pairs also indicates a high parametric effect of texture. © 2005 Wiley Periodicals, Inc.

Wideband miniature G-shaped antenna for dual-band WLAN applications

A wideband miniature G-shaped coplanar waveguide fed dual-band antenna for a wireless local area network (WLAN) is proposed. The proposed antenna has good radiation pattern and can provide two separate measured impedance bandwidths of 0.55 GHz (about 22.9% centred at 2.42 GHz) and 2.85 GHz (about 50.9% centred at 5.60 GHz), so that it easily covers the required bandwidths for WLAN operation. This design results in a small antenna size of 22 times 18.5 mm with the ground plane regarded as part of the antenna structure.     

在传统中探寻当代海报的本土设计

在设计国际化的影响下,中国现代视觉设计中充满了受西方影响的视觉语言,“国际化”视觉符号的泛滥与“本土化”视觉语言的失语视觉现象非常突出。作为当今社会人与人交流载体的海报设计,要走出一条“民族个性”的道路,就必须根植于民族文化土壤中,向传统学习,并进行具有创造性的转化,使传统文化符号在当代海报设计中既具有“民族个性”又有“时代性”,这样,我们海报设计才能真正走“国际化”。

中国炼铁系统的节能与环境保护

回顾了20世纪90年代以来,中国炼铁系统的节能和环境保护的进展.指出由于高炉喷煤技术的开发和推广,大大减少了焦炉的建设投资,真正从源头减少了铁前系统的能耗和污染.基于对炼铁系统二次能源的分析,从节能和减排温室气体来看,淘汰落后的小烧结、小高炉, 大力推广高炉TRT、高效干式除尘和利用高炉煤气发电及烧结余热回收利用等,将是今后工作的重点.
