布袋除尘器在锰铁高炉上的使用情况

我厂于1971年建成投产,有13米~3小高炉一座,自1972年以来改炼锰铁。高炉锰铁生产的特点之一是煤气含尘多而细,温度高,灰尘易凝结硬化,并含有较高的氰化物等有毒物质,因此煤气净化困

MooseFS中chunkserver负载均衡算法研究

作为云存储的核心基础平台,分布式文件系统的重要性日益凸显.分布式文件系统中数据存储在多台计算机节点上,必然会出现负载均衡问题.首先,对MooseFS的系统架构进行了研究,然后分析了MooseFS分布式文件系统中chunkserver选择算法,研究了chunkserver算法的负载均衡性能,最后对其进行了改进.经过实验测试对比,实验结果显示改进算法能显著提高chunkserver的负载均衡性能.     

Who Blocks Who: Simultaneous Segmentation of Occluded Objects

In this paper, we present a simultaneous segmentation algorithm for multiple highly-occluded objects, which combines high-level knowledge and low-level information in a unified framework.The high-level knowledge provides sophisticated shape priors with the consideration of blocking relationship between nearby objects.Different from conventional layered model which attempts to solve the full ordering problem, we decompose the problem into a series of pairwise ones and this makes our algorithm scalable to a large number of objects.Objects are segmented in pixel level with higher-order soft constraints from superpixels, by a dual-level conditional random field.The model is optimized alternately by object layout and pixel-wise segmentation.We evaluate our system on different objects, i.e., clothing and pedestrian, and show impressive segmentation results and significant improvement over state-of-the-art segmentation algorithms.     

品牌扩张是一碗迷魂药

当出现问题时,管理者总是喜欢将之归咎于执行,在他们看来,一个合乎逻辑、经过细致研究的战略,怎么会有错呢？到最后,他们也不知失败的原因所在     

数字网络系统对人类社会的影响

在繁忙的日常事务中,身不由己的我们是否可以使用计算机来摆脱百务缠身的窘境?每一个家庭是否都有能力购置计算机?每一企业或每一家庭是否都能与因特网联网并形成高速网络交流?无论是工作岗位还是家庭,能否使自己会像使用普通电话和邮件那样方便地掌握电子邮件,并作为日常通信交流的快捷手段?既然大家都拥有个人电脑并将其用于日常工作生
