入湖三角洲形成过程与淤积形态变化的实验研究

入湖三角洲的形成和发展过程是冲积河流演变的重要组成部分，三角洲尾闾水道生成、地貌演变机理更是河流动力学研究中的重点问题。利用自然模型法对入湖三角洲形成与形态发展过程进行模型试验，通过改变上游来沙和下游水位探究不同边界条件对三角洲平面形态、纵向推进、横向展宽及垂向抬高的影响。三角洲堆积体先呈舌状推进，随后随朵体的生长而变化，其长宽比先迅速增大后逐渐减小。上游来沙量越大，三角洲长宽比越小，下游水位越高对三角洲尺寸抑制越明显。三角洲纵向推进和横向展宽都呈现先迅速增长，后进入相对平稳期，并出现“台阶式”增长的趋势。来沙越多，横纵推进速度越快，越早出现突变式的增长。水位越高，三角洲越早以较小尺寸进入平稳期，突变周期越长，增长值越小。泥沙主要落淤在三角洲中下游，但较多来沙量会促使泥沙淤积在上游，并使上游河槽深度减小，中下游横截面坡度增大，三角洲整体纵向坡度也增大。     

A CTI System to Support the Seamless Workplace and Its Implementation

This paper proposes a CTI client/server coordination system exclusively for use with a smart phone. The system makes use of a CTI client, performing combined functions of a SIP phone and a Web browser. The proposed CTI client/server coordination system comprises SIP servers and Web servers, both of which are installed in enterprises, and CTI clients that run on smart phones in a mobile environment. Furthermore, the CTI clients perform the function of SIP phone by communicating with SIP servers. In addition, CTI clients can display telephone directories and logging of phone calls stored in Web servers. They can display screens of ordinary Web browsers. Here, one might switch between a SIP phone function and a Web communication screen with merely a single touch of the tab key. Consequently, smart phones in the mobile environment make it possible to conduct telephone meetings while browsing with a Web screen.     

Threshold computation for fault detection in linear discrete‐time Markov jump systems

This paper proposes a threshold computation scheme for an observer‐based fault detection (FD) in linear discrete‐time Markovian jump systems. An observer‐based FD scheme typically consists of two stages known as residual generation and residual evaluation. Even information of faults is contained inside a residual signal, a decision of faults occurrence is consequently made by a residual evaluation stage, which consists of residual evaluation function and threshold setting. For this reason, a successful FD strongly depends on a threshold setting for a given residual evaluation function. In this paper, Kalman filter (KF) is used as a residual generator. Based on an accessibility of Markov chain to KF, two types of residual generations are considered, namely mode‐dependent and mode‐independent residual generation. After that threshold is computed in a residual evaluation stage such that a maximum fault detection rate is achieved, for a given false alarm rate. Without any knowledge of a probability density function of residual signal before and after fault occurrence, a threshold is computed by using an estimation of residual evaluation function variance in a fault‐free case. Finally, a detection performance is demonstrated by a numerical example. Copyright © 2013 John Wiley & Sons, Ltd.

Robust ℋ︁∞ filtering for uncertain differential linear repetitive processes

The unique characteristic of a repetitive process is a series of sweeps or passes through a set of dynamics defined over a finite duration known as the pass length. At the end of each pass, the process is reset and the next time through the output, or pass profile, produced on the previous pass acts as a forcing function on, and hence contributes to, the dynamics of the new pass profile. They are hence a class of systems where a variable must be expressed in terms of two directions of information propagation (from pass‐to‐pass and along a pass, respectively) where the dynamics over the finite pass length are described by a matrix linear differential equation and from pass to pass by a discrete updating structure. This means that filtering/estimation theory/algorithms for, in particular, 2D discrete linear systems is not applicable. In this paper, we solve a general robust filtering problem with a view towards use in many applications where such an action will be required. Copyright © 2007 John Wiley & Sons, Ltd.

构造发电公司最优报价策略的机会约束规划方法

在采用暗标拍卖的电力市场环境中,发电公司在构造报价策略时需要对竞争对手的报价行为或市场电价进行估计,即报价决策是在不完全的信息基础上作出的,这样就不可避免地会带来一定的风险,因而需要进行风险管理.为避免现有的用方差度量风险时所存在的问题,作者借用了金融理论中的风险价值的思想,提出了与发电公司报价策略相关的风险的新的度量方法.在此基础上,构造了发电公司最优报价策略的机会约束规划模型,提出了将遗传算法嵌入蒙特卡罗随机模拟的求解方法.最后,用算例对所提出的模型和方法进行了验证.

Realization of 3-degree-of-freedom control using fine-grain parallel processing

The article reports a sprout of 3-degree-of-freedom (DOF) control. The limitation of feedback control, including 2-DOF control, has been raised for a long time; however, a suitable control theory for overcoming those limitations has still not been formulated. An underlying reason is that the disturbance-suppression performance and noise sensitivity cannot be decoupled. Several researches have tried to tackle this problem using a hardware approach, as a noise level depends on a hardware configuration. It should be noted that the hardware design expands spatiotemporal resolution of a system. This approach helps in reducing noise, namely, it works as the 3rd-DOF for a control system. Therefore, an improvement in the hardware design could be a new angle for solving a mixed-sensitivity problem. This article quantitatively presents the relation between noise-reduction performance and the spatiotemporal resolution, and provides a foothold for the 3-DOF control.
