捣固焦炉消烟除尘车的改造技术研究

焦炉是焦化生产的主要设备,也是焦化厂生产过程中的最大污染源。原焦炉装煤过程产生的大量烟尘,采用炉顶消烟除尘车除尘;出焦烟尘,采用拦焦车集尘罩导入消烟除尘车二者配合除尘;装煤过程中消烟除尘车处理效果不理想,还释放大量烟尘。经过改造试验对比,第二次改造后的方案即采用间距为500mm,互相垂直的两组折流板结构,两组折流板底部各增加一组旋向相反的螺旋喷淋器,洗涤折流板,再次起到除尘作用。现烟气排放已达到并优于环保标准,烟尘排放量远远低于国家标准,减排显著。

颜色管理中的白场适应问题（英文）

在某种媒介上再现源自于另一种媒介的颜色时（比如印刷再现显示图像）,最常用的方法是将源媒介的白场与目标媒介的白场相匹配。但是这种方法仔在一定的局限。本研究通过一系列的实验,获取了一些心理物理学的数据,以便更清楚地认识颜色管理中的白场适应问题,开发更有效的颜色管理解决方案。在此基础上,评价了在采用白场补偿的条件下,不同承印物上印刷输出匹配的可接受性,并测定了承印物色差对此匹配的影响程度。     

How to design good experiments in marketing: Types,examples, and methods

In this article, we present key tenets of good experimental design and provide some practical considerations for industrial marketing researchers. We first discuss how experiments have the ability to assess causal claims. Next, we provide an experimental taxonomy table, which brings out the value and limitations of different types of experiments and maps the various goals of business marketing research within each category. Here, we pay particular attention to field experiments since they provide experimental realism by measuring respondents' actual behavior. We also provide a thorough discussion on important practical issues such as questions on experimental design, sample size, and how to involve business organizations in the implementing steps. The paper concludes by stressing the importance of combining data types (e.g., field plus laboratory experiments) and by offering methodological advice on how to analyze experimental data in marketing.     

两步法快速复原噪声模糊图像

本文提出了一种两步复原法,以用于复原被脉冲噪声干扰的模糊图像。第一步,对离群点进行识别,即那些疑似被脉冲噪声损坏的像素,并将剩余的像素视为基本非离群点。第二步,基于非离群像素,利用变分法对图像进行去模糊和去噪声。实验结果显示,使用该方法复原后图像的峰值信噪比dB值较采用典型变分法有所提高。

Online content match-making in B2B markets: Application of neural content modeling

Business-to-business (B2B) sellers need to enhance content marketing and analytics in an online environment. The challenge is that sellers have data but do not know how to utilize it. In this study, we develop a neural content model to match the content that B2B sellers are providing with the type of content that buyers are seeking. The model was tested with two experiments using a dataset that combines cookie-based browsing data from 74 B2B seller companies over a period of fourteen months. In total, the data comprises 180 million browsing sessions tracked via 11.44 million cookies from 34,170 buyer companies. In the first experiment, we study the content in the sellers' own channels, and in the second experiment we study paid channels. With these experiments, we illustrate that browsing data can be combined with marketing content data to evaluate and improve the content-marketing efforts of B2B seller firms. Since the development of digital information technologies (DITs) has made the B2B buying process more buyer driven, our neural content modeling approach can be used to create B2B analytics that re-empower the sellers.     

运用子带域条纹实现彩色转灰度图的可逆映射

在近年来提出的彩色图像转灰度图的可逆映射概念中指出，彩色图像被映射成条纹后，接收者可用这些条纹通过小波变换、降低采样彩度宽度和重置高频区域的方法来实现彩色图像再现。主要思路是使用黑白打印机打印出带有彩色的图像，然后扫描文件并再现彩色。本文提出了一个更为有效地抗打印、扫描噪声的方法，即使用冗余再现彩度，将其嵌入总子带区域转换中的多重子带中，即将彩度分散到不同的子带中。从理论角度证实了为了减小由白色噪声引起的误差方差，彩度应该置于许多子带中，而不是形成线性组合。此外，本文还介绍了寻找最佳线性转换的方法，该方法可以在更普遍的彩色噪声下将彩度嵌入子带中。通过对噪声进行分析确定上限，以指导彩度嵌入子带时所需子带的数量。实验结果均在真实打印和扫描条件下进行，并使用了模拟的打印、扫描路径。

Comparison of a new bootstrapping method with parametric approaches for safety stock determination in service parts inventory systems

In this paper, we address the problem of forecasting and managing the inventory of service parts where the demand patterns are highly intermittent. Currently, there are two classes of methods for determining the safety stock for the intermittent item: the parametric and bootstrapping approaches. Viswanathan and Zhou (2008) developed an improved bootstrapping based method and showed through computational experiments that this is superior to the method by Willemain et al. (2004). In this paper, we compare this new bootstrapping method with the parametric methods of Babai and Syntetos (2007). Our computational results show that the bootstrapping method performs better with randomly generated data sets, where there is a large amount of (simulated) historical data to generate the distribution. On the other hand, with real industry data sets, the parametric method seems to perform better than the bootstrapping method.     

Jobs Lost, Jobs Regained: An Analysis of Black/White Differences in Job Displacement in the 1980s

Over the period 1982–1991, black men were considerably more likely to experience job displacement than were white men, and following displacement, the likelihood of reemployment was substantially lower for black men. Using data from the 1984–1992 Displaced Worker Surveys, we find that black men experienced rates of job displacement that were 30 percent higher, and reemployment rates that were 30 percent lower than the corresponding rates for white men. We find that racial differences in education levels and occupational distributions explain part of these racial gaps in job displacement and reemployment, whereas racial differences in industry distributions worked to narrow these gaps.
