Description
Summary:We, the editors and publishers of Mathematical and Computer Modelling of Dynamical Systems (Taylor & Francis) and Journal of Vibration & Control (SAGE) are retracting the following articles: A. Cargo pendulation suppression of ship cranes with elastic booms, Authors: D. Soeffker, Y.M Al- Sweiti*, Mathematical and Computer Modelling of Dynamical Systems, published by Taylor & Francis. Volume 13, Issue 6, 2007, pages 503–529 DOI: 10.1080/13873950701214424 B. Modelling and control of an elastic ship-mounted crane using variable-gain model-based controller, Yousef Al-Sweiti and Dirk Soeffker, Journal of Vibration & Control, published by SAGE. Volume 13, Issue 5, 2007, pages 657–685 DOI: 10.1177/1077546307074246 We are now aware that these articles contain sections that substantially overlap with each other and with the following published papers: 1. Yousef Al-Sweiti and Dirk Soeffker, "‘Modelling and control of an elastic ship-mounted crane using variable- gain model-based controller," Proceedings of the Institution of Mechanical Engineers, Part K: Journal of Multi-body Dynamics, December 1, 2006; vol. 220, 4: pp. 239–255. 2. Yousef Al-Sweiti and Dirk Soeffker, ‘"Planar cargo control of elastic ship cranes with the ‘‘Maryland Rigging’’ system,’’ Journal of Vibration and Control, March 2007, vol. 13, no. 3, pp. 241–267. It is noted that Article (1) has already been retracted by SAGE. We have conducted a detailed investigation with regards to the originality of Articles A and B, and have consulted with each other on the appropriate course of action. Taylor & Francis and SAGE are in agreement that Articles (A) and (B) bear substantial overlap to each other and Article (2), particularly in the Mathematical Modeling and Observer and Controller Design sections. The Publishers are thus retracting Articles A and B from publication in Mathematical and Computer Modelling of Dynamical Systems and Journal of Vibration and Control. The authors failed to cite, reference, or properly acknowledge their previous work nor properly identify or quote extracts from that work which subsequently appeared in, and appeared original to the articles (now retracted) in, Mathematical and Computer Modelling of Dynamical Systems and Journal of Vibration and Control. The authors were therefore in breach of the rules of submission for Mathematical and Computer Modelling of Dynamical Systems and Journal of Vibration and Control, and of the warranties made to both Taylor & Francis and SAGE rega
