Feedback control for providing QoS in NoC based multicores

In this paper, we employ formal feedback control theory to achieve desired communication throughput across a network-on-chip (NoC) based multicore. When the output of the system needs to follow a certain reference input over time, our controller regulates the system to obtain the desired effect on t

A directional global sparse model for single image rain removal

Rain removal from a single image is an important issue in the fields of outdoor vision. Rain, a kind of bad weather that is often seen, usually causes complex local intensity changes in images and has negative impact on vision performance. Many existing rain removal approaches have been proposed rec

略论建设工程转包与合同转让、劳务分包的区别

所谓建设工程的转包是指承包人承包建设工程后,不履行合同约定的责任和义务,将其承包的全部建设工程转给第三人或者将其承包的全部工程肢解以后以分包的名义分别转给第三人承包的行为.其本质属性就是,承包人不履行原合同中全部的建设工程任务,在不退出原合同关系的前提下,由转承包人与发包人间建立新的事实合同关系.一、建设工程转包与合同转让的界定合同转让指的是合同法意义上的建设工程合同权利义务概括转让,即指建设工程合同的当事人将其在建设工程合同中的权利义务一并转让给第三人,由第三人概括地继受这些债权债务的法律行为.建设工程合同转让与建设工程合同转包有许多相似之处:(1)转包与转让均是将建没工程合同权利义务交由第

运用微博开展大学生思想政治教育研究

作为一种得到大学生青睐的新兴网络生活方式,微博已在当前大学生思想政治教育工作中发挥越来越重要的作用。本文对微博在上海政法学院大学生思想政治教育中的认知和使用现状进行实证调研的基础上,指出微博使思想政治教育既面临困境,也带来机遇。进而提出要正确树立微博语境下“疏而不堵”、“标本兼治”和“就虚击实”的大学生思想政治教育新理念,科学定位微博在大学生思想政治教育中“四大平台”的功能,并通过在高校构建全员育人的“微博集群”,使思想政治教育工作者成为引领学生的“微博达人”,建立网上网下“虚实结合”的教育机制,从而创新大学生思想政治教育。

非圆齿轮多齿轮泵原理及其流量特性

本文提出了一种基于非圆齿轮的多齿轮泵,并讨论了其流量特性.非圆齿轮的径向尺寸是连续变化的,依靠这种径向尺寸的变化并结合齿轮的连续转动,就可以造成泵体与齿轮之间的容积变化,从而达到输送液体的目的.2齿轮的非圆齿轮泵虽然结构简单,但是流量波动非常大,难以产生实用价值.在2齿轮的非圆齿轮泵基础上,增加1个齿轮就可以得到3齿轮非圆齿轮泵.当3齿轮非贺齿轮泵的中心轮满足一定条件时,其两侧产生的流量能够相互补偿,极大地降低了流量波动,获得了具有实用价值的多齿轮泵.这里比较详细地讨论了3个三阶椭圆齿轮作为工作齿轮(称为3-3-3组合)时的流量特性.

陶景洲 一张口就计时

在西方国家,有关医生和律师的笑话最多,而两者相比之下,又以律师最为突出。如果要究其原因,也许与近几年来日益低落的律师社会形象有关。在越来越多的人眼里,律师跟生意人似乎找不出大的区别,有钱就可买到律师的“服务”,这也就难怪有人拿律师“开涮”了。中国改革开放以后,允许外资律师行进入内地法律服务领域的政策使这些笑话中的主角陆续来到了中国,不过他们可不是来制造笑话的,而是为了在庞大的法律服务市场中分一杯羹。而事实上,外资律师行在中国的业务目前已经从中国法律服务市场上切走了一大块蛋糕。这也没什么值得紧张的,律师业的竞争并没有想像中那么残酷。毕竟,各个国家都有自己的传统文化,社会制度和法律渊源,一个真正的

商业贿赂犯罪研究%On the Crime of Commercial Bribery

在我国,商业贿赂是随着改革开放、商品经济的发展而产生发展起来的一种经济现象.商业贿赂犯罪是一种新型经济犯罪,主要表现为在经济活动中,经济参与一方主要依靠贿赂行为去引诱对方与之发生交易,而不是在正常的价格、质量、服务等方面的竞争,此种行为妨害了市场的公平竞争,直接导致了其他经营者失去了交易的机会.商业贿赂行为的滋生蔓延,必然会扰乱社会主义市场经济秩序的健康发展,破坏公平竞争原则,影响我国的投资环境和日益增长的国际形象.鉴于此,研究商业贿赂犯罪的概念、特征等基本问题,探讨立法的完善工作,对于严密法网、开展专项工作有着重要的意义.

面向需求侧响应的基于负荷预测三相负载调度算法

针对需求侧响应下的三相负载动态不平衡及电能资源浪费问题,提出了基于负荷预测的三相负载调度算法.该算法使用基于滑动窗口的组合预测模型进行高精度的负荷预测,在此基础上,根据限电指标与预测三相负荷之间的相对大小关系,构建最小化不平衡度及最大化用电效率的多目标优化调度模型,并采用主要目标法、变尺度法和可行方向法求解三相负载的注入及削减量,最终给出相应的三相DR命令,从而降低三相负载不平衡度,提高用电效率.仿真实验结果表明,使用基于负荷预测技术的三相负载调度算法,与不使用调度策略的数据相比三相负载不平衡度平均减少5%,而用电效率平均增加20%.
