对输出特性文件不同再现意图色域的分析

设备的特性文件中记录了设备的颜色特性和介质、观察颜色的条件等信息,是进行设备间颜色转换的依据,是色彩管理的要素之一。正确理解不同设备的色域特点以及设备在不同再现意图条件下的色域特点,对正确使用设备的特性文件和正确选择再现意图十分重要,对理解色彩管理的原理也很有帮助。利用Argyll软件对典型输出设备的特性文件以及4种不同再现意图下的色域进行了分析,讨论了不同再现意图下色域改变的特点。对实验结果的分析表明,目前的ICC色彩管理系统存在某些隐含的缺陷。

Six unique load shapes: A segmentation analysis of Illinois residential electricity consumers

Many electricity policies have disparate impacts on consumers with different load shapes. This study applies k-means clustering to 2.5 million Illinois customers, and matches six resulting clusters with demographics. Flatter load shapes were more likely in urban and low-income areas, with high-volume, peak usage more likely in high-income/suburban areas. This highlights potential for grid cost reduction through DR programs targeting suburban areas, and illustrates potential cross-subsidization intrinsic to common electric rate designs.     

Experimental evaluation of underride analysis techniques and empirical validation of a new analytical technique

Accident reconstructionists are often faced with damage patterns and locations on vehicles that are not well defined by available barrier impact data. One such example is a frontal underride collision. Underride impacts occur when there is a height mismatch between the primary structural components of the impacting vehicles, and the vehicle with the lower height is forced beneath the structure of the other vehicle. The lack of structural engagement typically allows for significantly different damage patterns due to the inherently lower stiffness of the underriding vehicle's contacting surfaces coupled with complex interactions between varying surfaces. In this study, a series of two-vehicle impact tests between a small pickup (bullet vehicle) and a large dump truck (target vehicle) were performed and studied. These tests involved a severe underride configuration in which the dump truck bed's vertical alignment was above the base of the windshield of the pickup. Coupled with these impacting surfaces was a single vertical support, a remnant of a commonly referred to ICC (Interstate Commerce Commission) bumper, which caused a narrow object-type impact, but did not extend down to the pickup's bumper. Multiple prior authors’ analytical and empirical relationships to predict impact speed based on crush damage were evaluated using the results of these tests as well as other published underride tests. No single model was sufficient at predicting the mixed mode of impact present in these impact scenarios. However, a system of equations was developed to predict the impact parameters utilizing a combination of previously reported methods and a new empirical relationship presented in this study. This new method shows high correlation and supports the authors’ hypothesis that separate crush models can be applied to multiple discrete areas of a vehicle and then combined to form a more complete predictive systematic model.     

印前设备的色彩管理

伴随着数字印刷科技的发展，先进的色彩管理技术得到了广泛应用。鉴于不同的设备有各自表现颜色的方法，国际色彩联盟提出了基于ICC Profi1e（设备特征文件）的色彩管理解决方案。 ICC Profile是用于记录每个设备如何表现颜色的跨平台文件格式，每一种设备都有各自再现颜色的ICC Profile。在相同的颜色设备和转换引擎的条件下，色彩管理的精度取决于ICC设备特征文件的精度。
