The problem discussed in this paper is the effect of latency time on the OGY chaos control methodology in multi chaotic systems. The Smith predictor, rhythmic and memory strategies are embedded in the OGY chaos control method to encounter loop latency. A comparison study is provided and the advantages of the Smith predictor approach are clearly evident from the closed loop responses. The comple...

In this paper, the problem of predicting times to failure of units censored in multiple stages of progressively hybrid censoring for the proportional hazards family is considered. We discuss different classical predictors. The best unbiased predictor ($BUP$), the maximum likelihood predictor ($MLP$) and conditional median predictor ($CMP$) are all derived. As an example, the obtained results ar...

Automated inspection of Printed Circuit Boards(PCB's) is essential if 100% repeatible inspection is to be carried out. The cost of most commercially available systems for automatic visual inspection of PCB's are beyond the reach of many small to medium manufacturers. The principle objectives of our research is to develop and integrate a micro-computer based image analysis system specifically fo...

in this paper, behavior of teleoperation systems with modeling error and delay time error in smith predictor is discussed. in teleoperation systems, modeling error is inevitable. this paper discusses stability of teleoperation systems with modeling error. first, error of delay time in teleoperation systems by using of internet as communication channel is considered and the performance of smith ...

The aim of this research is to create and to normalize the marital infidelity predictor test. The method used in this study is post-event and it uses the survey technique. The statistical population consists of women residents in Tehran and for investigating the subject and determining the technical characteristics of the questionnaire, 200 individuals are selected, through cluster sampling, wh...

aim and background: some of obsessive-compulsive disorder (ocd) patients believe that their unpleasant thoughts can influence the external events. the aim of this study was to investigate the correlation between the contents of thought-action fusion and obsessive-compulsive symptoms in patients with ocd. methods and materials: in this cross-sectional correlative study 60 ocd patients selected b...

Astrom et al. have proposed a new Smith predictor to control the process with an integrator and a long time delay. Though the method provides significant performance improvement, it fails to give effective tuning rules even when the integral constant is equal to 1. In this paper the method is extended to the general integrator/time delay process. A clearer and more logical design procedure is f...
