First, confirming the positive function and finding some problems of the order-based cultivating mode by the acquaintance with the teaching situation of domestic universities. Then, analyzing the source of the issue and offering advice on it by experience on the order-orientated talents training of East China Jiaotong University.
Basing on Fabry-Perot fiber optic strain gauge integrated with DSP and the accomplished hard system, principle of Fabry-Perot fiber optic strain gauge integrated with DSP was discussed. Data collecting and processing method of real outputting signal were deeply discussed. Discrete gap transform (DGT) is presented based on FFT and used to obtain the gap of Fabry-Perot fiber optic sensor.DGT completes the direct transformation of the signal from wavelength domain to cavity length domain. In addition, the experiments based on equal strength beam system were carried out. Experimental result shows that previous data processing method is effective. The result is primarily in accordance with that of real loading processing, and shows the method developed by this paper is feasible and effective.
In this paper, considering the stability and robustness of the aircraft, the flight control system is designed following the aspect of high flexibility and low cost. Comparing with the flight control system of super-size high-subsonic Unmanned Aerial Vehicle (UAV) in the world, the system presented in this paper has adopted the inimitable control technique of flying-off course、low-cost combinatorial navigation strategy and the advanced safety scheme, which can guarantee the performance, degrade the cost and extend the airspace and groundspace of the aircraft.Through quite a few simulations, the results show that this system can guarantee the attitude and altitude stable. The error between the flight path and programming path is very small. Flight curve is prefect; and the system performances can be achieved completely.
With the widespread use of the Internet, reducing power consumption to extend network lifetime while maintaining the communication connectivity and covering the target region completely has become one of the most important challenges in designing future Internet networks. After the comparison of some existing methods, such as measuring networks state and evaluating flow-jamming attack on network flow, we present a new form of network traffic flows, in which end systems or hosts have three basic states: on, off and asleep. In this paper, we first give a brief review on the existing techniques, and particularly consider ldquoresearch on architecturerdquo as a process rather than an event. Then, we propose a framework for initial exploration of supporting selective connectivity, whereby a host or a router can choose whether to be ldquoconnectedrdquo or ldquodisconnectedrdquo. The proposed approach is formulated as an optimization problem for both selective connectivity and resource exhaustion in Internet. We show that this technique is able to provide a foundation for design of future protocols to improve the actual Internet architecture.
Objective To study the cause of death and mechanism after(TACE)in China during the past 14 years.Methods Related repots in Chinese Medical Current Content(CBM)and National Knowledge lnfrastruc ture(CNKI)from January 1994 to June 2008 were retrieved.The cause of death and mechainsm after TACE wer e analyzed.Results A total of 150 patients who died after TACE were reposed in China during the past 14 ye ar s.84%eases were caused by liver lunction failure,upper gastrointestinal bleeding and rupture of liver cancer. 78.7%cases died one month postoperation.Conclusion Liver function failure.upper gastrointestinal bleeding and rupture of liver cancer are the main complications which Can cause death and the majority cases died early.
Key words:
transcatheter hepatic arterial chemoembolization; cause of death; mechanism
A novel surface roughness optical fiber sensor is presented. It consists of a light emitting diode source, an Y-tap, a probe made up of self-focusing optical fiber, a photo- detector setup, and a fuzzy system. Its principle is based on the intensity-modulated light from an object surface to be measured. The fuzzy algorithm was used to treat the data obtained from photo-detector setup. Since the fuzzy algorithm can map input and output perfectly, the measure accuracy was improved and the measure range was expanded.
Six Sigma quality management takes statistics method as basic method and Six Sigma quality management can not be successful without statistics method.Before China's enterprises advocate Six Sigma quality management,the research and application of statistics method must be attached importance to.The popularizing and disseminating statistics method and technology and quantifying enterprise management objective can rapidly promote domestic enterprise product competence and promote real-time enterprise management ability to lay the concrete foundation for Six Sigma quality management.
The hydrolysis loss of digested alumina from bauxite reentering into the bauxite residue has always been the research focus during the Bayer process. The stability of sodium aluminate solution after digestion with different lime additions during the dilution process from a diasporic bauxite was studied, and the mechanism by which the lime addition affects was also discussed. The molar ratio, silica index and hydrolysis degree of diluted liquor after digestion are highly affected by the lime addition, and the corresponding alumina extraction efficiency of bauxite and the Na2O to SiO2 ratio of bauxite residue are changed. The stability of diluted liquor is firstly increased by the lime addition below 15% of the bauxite, and then decreased as the lime addition increases. The mineral content and proportion of desilication products precipitating during digestion are the main factors affecting the stability of sodium aluminate solution after digestion.
The purpose of this essay is to review empirical literature on internal control weakness over the past seven years. I use an analysis framework consisting of determinants (corporate governance and other affecting factors) and economic consequences (accounting information quality, market reaction, cost of equity, debt contracting) of weakness disclosure and its remediation. Basic findings of prior studies agree that corporate governance and firm characteristics influence the presence of control problems and their remediation. In turn, the effectiveness of internal control impacts the quality of financing reporting, auditor reaction (auditing fees and audit delays), insider trading and leads to capital market consequences (the weakness disclosures affect debt contracting). More internal control studies combine with capital market and provide evidence that SOX are not always effective. Overall, these findings contribute to profession by suggesting that the disclosures of internal control deficiencies generally convey incremental information on the quality of financial reporting to investors. This review integrates and assesses current internal control weakness research and offers some suggestions for future study.
Taking Tai Shan(Hong Tu),a brand line covering middle and high price cigarettes,as experimental objects,the structure of composite cut tobacco,the fine content in finished product and the consumption in processing were determined at different cut tobacco widths set according to modularized drying methods,meanwhile,the effects of cut width combination on cigarette quality were investigated by sensory quality evaluation.The results showed that: for flavor grade module with thin plate drying the cut tobacco width set at 0.9 mm,and filling grade module with air drying set at 1.0 mm,the ratio of tobacco breakage,the tobacco fines sieved from the cut tobacco came out of the silo, the dust content in cigarette and rejecting rate of loose end cigarettes decreased by 0.39%,17.1 kg,0.79 mg/cig.,0.83%,respectively;and the cigarette sensory quality score improved by 0.4.
