Customary roller conveyors as a part of intralogistic facilities are designed, so that there occurs only a state of steady stiction between the belt and the rollers even in transient sequences. However, wear-out effects can lead to a change in the material characteristics and belt-tension and thus to a change of the performance characteristics of the conveyor system. In order to investigate the influence of such effects on the system behaviour, an analytical electromechanical model presented in a previous publication has been enhanced by considering possible slip between drive belt and rollers. Simulation results are compared with measurements, giving a good overview on how different operating states of static and kinetic friction influence the transient behaviour of the system.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116193936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finally experiments are simulated by MATLAB, and experimental results demonstrate that the improved moments are invariant to the translation, rotating and scaling of objects, the recognition rate is relatively high and the proposed algorithm has some practical value.

Motion parameters are derived from the principle of kinemics. Constraint equations are deduced by means of recursion based on the assumption of rolling wheels without slipping. Computer simulations are carried out on a virtual prototype. The results show that there are seven generalized coordinates in the bicycle system mentioned in the paper. Among them there are only four independent speeds. They are the rotational speed of the roll angle of the frame, the two rotational speeds of the two wheel forks, and the rotational speeds of either wheel. The rotational speed of yaw angle of frame, the rotational speed of the pitch angle of frame, and the rotational speeds of the other wheel both are the function of the four independent speeds. The simulation results based on virtual prototype are consistent with the theoretical analysis. Then the validity of the theoretical analysis of nonholonomic constraints is verified accordingly.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129936487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On one hand, it helps the consumer to find the suitable products in a much easier way. On the other, it explores the potential need of the consumer therefore steps up the deal. In order to make improvement on user stickiness, the recommendation system is now recognized as a vital role in intensive competition. However, it has an obvious weakness when helping consumers choose high-tech products where it requires much strict technical knowledge and it is not effective to recommend new products due to the lack of ratings. This research provides a new recommendation method related to high-tech products based on consumer's preference with less complexity and more effectiveness. It aims to make the new products equivalent to the old ones during the computing process therefore improve the effectiveness of new product recommendation.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130955954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A more practical and general model of actuator gain faults is adopted. The stochastic packet dropouts are considered existing not only between sensor and controller but also between controller and actuator. Thus, the NCS is modeled as Markovian jump linear system with four operation modes. Sufficient conditions to ensure that the NCS is stochastically stable and satisfies the guaranteed cost performance are developed. The corresponding guaranteed cost fault-tolerant controller is also designed.

The coordinates of space vector are integeres by a simple coordinate transformation, and the basic vectors are achieved by the reference vector coordinate upward and rounded down respectively, whose effective time is calculated by the principle of Volt-seconds balance. The switching state equation is introduced to control the neutral-point voltage balance and the appropriate degrees of freedom are choosed.
