"A particularly interesting finding of this study is that the vaccine achieved fairly good control of blood pressure in the early morning hours," said Juerg Nussberger, M.D., Division of Angiology and Hypertension, Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland, who presented the study in a Tuesday media briefing.
Juerg Nussberger博士认为与降压药物相比,高血压疫苗具有以下优势:(1)降压药物半衰期短,无法稳定控制清晨血压,而这正是高血压疫苗所擅长的;(2)高血压疫苗只需每四周注射一次,依从性明显好于降压药物;(3)高血压疫苗可有效控制血压,而降压药物只能使四分之一的患者血压得到成功控制。

Servo controller is key part of antenna control system.In some servo controller,classic PID control algorithm is adopted. In order to improve precision of control system,the integral parameter has been turned too big to use because it will cause integral saturation which depress system performance.On the other hand,ISA bus is used to communicate between servo controller and main computer.ISA is low speed interface protocol,it cannot provide more data for complicated real time position control in servo controller.
伺服控制器是天线伺服控制系统的核心环节,经典的PID控制算法在整定时整定出的积分环节参数较大,很容易出现积分饱和,造成控制精度的降低;另一方面伺服系统中伺服控制器与主控计算机通过低速的ISA总线进行通信,无法满足控制器进行复杂的位置控制运算所要求的实时大信息量的数据传输。

It can also refer to someone with a limited number of things that they want done a specific way; professor of clinical psychology Les Parrott wrote that "Control Freaks are people who care more than you do about something and won't stop at being pushy to get their way."
这种心态可能是一种优越感作祟,相信他人无法自己处理好事情,或者是害怕他们一旦不去控制所有细节,事情会失控。有时候,有些控制狂只是希望控制一切,而产生一种权力在握的良好感觉。

Therefore, a design scheme via LMI approach is presented in order to improve the system robustness. By using the LMI approach, the attitude controller design is reduced to a convex optimization problem based on the polytopic system. Since there are some degrees of freedom when solving the LMI, it is available to use this kind of freedom to achieve multi-objective control within this framework.
通过仿真发现采用经典控制方法设计的姿态控制系统在飞艇模型参数以及工作条件变化较大时,无法保证良好的控制效果,因此,为了提高系统的鲁棒性,本文采用基于LMI的方法对姿态控制系统进行了设计,并对所设计系统进行了有约束的多目标优化。

this paper makes the gas remote monitor network as background to do some research on the qos guarantee of the network.qos is a synthesis guide line which can be used to estimate the degree to satisfy with some server,which is a technology to solve the problem of delay and congestion in network.it must integrate multi-qos mechanism to get good qos guarantee in the practical application.three qos models in the ip net application and homologized affective factors are demonstrated.meanwhile,the field of qos protection strategy arrangement in shaanxi coal mine gas network has been picked up as the example.for this situation,the comparison to the different qos models is doing strictly.by combining the tcp congestion control arithmetic with ip congestion control arithmetic,the paper also emphatically describes the corresponded arithmetic model for that.stimulatingly,it is promoted the qos characteristic over-area effectively,which it is based on the original single congestion control.

In view of these shortcomings this frequency meter has made the radical innovation in the design its merit is: Uses the core component is the advanced monolithic special-purpose frequency measurement component -- monolithic frequency meter the integration rate is high the volume is small consumes the electricity province function has realized the frequency meter high integration and the microminiaturization; So long as the monolithic frequency meter adds on the crystal oscillator the measuring range choice the frequency demonstrated and so on the very few components then constitute DC to the 10MHz miniature basic frequency measurement electric circuit; But the biggest merit was this frequency meter has realized monolithic frequency meter frequency sampling electric circuit and the monolithic microcomputer three between hardware and the software connection completely caused the frequency measurement measuring range the choice the frequency data survey the sampling as well as the code frontier transformation and the data dump possible monolithic microcomputer software programming automatically to carry on thus has realized the frequency measurement and the sampling work intellectualizes completely causes this system already to be possible to constitute a miniature intelligence to measure rate the instrument core electric circuit independently also might take in the large-scale automatic control or a test system intelligent subsystem.
摘要传统的测频仪器体积很大,耗能量大,主要靠手工操作,而最大的缺点是不可编程,其量程转换、数据测量、采样控制和处理等均不能通过程序指令来进行控制,无法作为一个微型智能子系统与某一大型自动控制或测试系统进行接口。针对这些缺点,本频率计再设计上作了根本的革新,其优点是:所用核心器件是先进的单片专用测频器件——单片频率计,集成度高,体积小,耗电省,功能强,实现了频率计的高度集成化和微型化;单片频率计只要加上晶振、量程选择、频率显示等很晌慰的器件即可构成一个DC至10MHz的微型基本测频电路;而最大的优点则是本频率计完全实现了单片频率计、频率采样与单片微机三者之间的硬件与软件接口,使得测频量程的选择、频率数据的测量、采样以及编码的边境转换和数据的转储均可能过单片微机的软件编程自动进行,从而实现了测频与采样工作的完全智能化,使得本系统既可独立构成一个微型智能测率仪器的核心电路,也可作为大型自动控制或测试系统中的一个智能子系统。关键词高度集成化,单片机,频率计,电路
