Predictive models for geometric shape deformation constitute an important component in geometric fidelity control for three-dimensional (3D) printing. However, model building is made difficult by the wide variety of possible process conditions and shapes. A methodology that can make full use of data collected on different shapes and conditions, and reduce the haphazard aspect of traditional statistical...
During construction of high buildings, subsidence increases as load increase, and safe or not and development trend are need to be known, so the method for predicating the deformation of high building is presented through the optimized method of grey system theory. The GM(1, 1) model establishing, the raw sequence's transformation and model optimized method are discussed, and the parameter optimized...
This paper continues to build the gray system model to analyze building deformation, based on the analysis of traditional model of gray system theory, making comparison between the original observation data series and the predicted progression which are concluded by the built model, then to put the residuals into system. Facts have proved that to use the residual gray combination model in building...
