A hybrid time-delay prediction method for networked control system

This paper presents an Ethernet based hybrid method for predicting random time-delay in the networked control system.First,db3 wavelet is used to decompose and reconstruct time-delay sequence,and the approximation component and detail components of time-delay sequences are fgured out.Next,one step prediction of time-delay is obtained through echo state network(ESN)model and auto-regressive integrated moving average model(ARIMA)according to the diferent characteristics of approximate component and detail components.Then,the fnal predictive value of time-delay is obtained by summation.Meanwhile,the parameters of echo state network is optimized by genetic algorithm.The simulation results indicate that higher accuracy can be achieved through this prediction method.

知识资本:中国参与全球创新网络的关键

对于当前世界发达经济实体中的领袖而言,中国到底是威胁还是机遇?在全球商业、工业、政府和学术观察人士中间,这一争论仍在延续.中国在全球工业中的显著作用已经无庸讳言.今天,中国制造了世界上50%的照相机、30%的空调和电视机、25%的洗衣机及接近23%的冰箱.制造业占中国GDP的53%,出口额的90%,进口额的85%以及吸引投资额的70%.中国是世界上(继美国、日本和德国之后)的第四大生产国,并正以惊人的增长速度向前发展.     

整合江湖谁称霸 AMD 780G对决NVIDIA MCP78

AMD 780G 作为超威派7系列整合芯片组掌门人,AMD 780G算得上乱世英雄,因为它是首款正式上市的DirectX 10整合主板,引领着整合江湖进入到另一个新"视"界.这款芯片组全面支持新一代K10处理器,支持Hyper Transport 3.0总线与PCI-E2.0显卡插槽,并且内建了性能等效于Radeon HD2400 PRO的显示核心,从而全面支持UVD高清解码引擎.另外,这款整合芯片组还特别对混合交火技术提供支持,从而让AMD 780G这位独行侠行走江湖一段时间后,便获得了众多派别的鼎立相助,江湖地位日渐攀升.

Study of the response of the area of the palm to impact: Relationship between the physical characteristic of the palm impact and the subject perception of the severity of the palm impact

Even though using the hand as a hammer causes injury, the practice continues, and may be increasing, in industry and in jobs that require intensive manual labor. This was an exploratory study aimed at measuring the relationships between the forces of strikes, the relative angles of strikes, and/or the number of strikes (up to 3) with the perception of severity of strikes when using the base of the palm of the hand. Eight subjects struck a metal force plate with the base of the palm of the hand at three levels of force, three levels of angle with respect to the surface of a force plate, and with three different numbers of times in a trial. Subjects were then asked to give a psychophysical rating after each trial. The subjective perception of the severity of each impact and force-time curves were recorded. From each force-time curve, peak force, maximum acceleration of force application, and the area of the force curve from initiation to peak were determined. Sixteen ANOVA models were analyzed.

Reconstruction of the corrective component of the transfer function of the interpolator in the process of calibration of the precision event timer

The peculiarities of the interpolation method based on digital signal processing are considered. It is shown that the transfer function of the interpolator may be represented by the composition of two functional components. A nonstatistical method of reconstruction of the form of the corrective component of the transfer function based on processing of the scatter diagram of the ordered pairs of the experimental and predicted data is investigated. It is shown that such pairs may be obtained in the process of periodic event flow timing with estimations of the time positions of the signal and the predetermined instants of the event occurrence being elements of the ordered pairs. The efficiency of the reconstruction method is illustrated by the experimental results.     

Convergence,the university of the future and the future of the university

 The paper questions the ability of current university systems to respond appropriately to the complex demands of an Information Economy. It argues that new relationships between creative subjects and technology require new thinking about the nature and purpose of universities per se. In particular, attention is drawn to the growing involvement of the private sector in higher education. It is argued that it may not be appropriate to think of the `university of the future' in terms of current public sector and quasi public sector institutions, but rather in terms of an emporium, based on an international trade in educational services, and with the `University' as we now understand it occupying the functions of licensing, quality assurance and cultural custodianship.
