摘要： This paper presents a new paradigm of explicitly modeling and harnessing the data structure to address the inverse problems in structural dynamics, identification, and data-driven health monitoring. In particular, it is shown that the structural dynamic features and damage information, intrinsic within the structural vibration response measurement data, possesses sparse and low-rank structure, which can be effectively modeled and processed by emerging mathematical tools such as sparse representation and compressed sensing, low-rank matrix decomposition and completion, as well as the unsupervised multivariate blind source separation. It is also discussed that explicitly modeling and harnessing the sparse and low-rank data structure could benefit future work in developing data-driven approaches toward rapid, unsupervised, and effective system identification, damage detection, as well as massive SHM data sensing and management.

摘要： Bio-inspired design was introduced as an alternative method to encourage breakthrough innovations during design projects by stimulating analogical reasoning and thinking of designers. However, the method did not perform as well as researchers expected because most designers, who are novices in the fields of biology and ecology, cannot infer the proper analogue (i.e. biological system) from nature. To resolve this fundamental problem, a causal model based representation framework for ‘analogical reasoning’ - searching and selecting the biological systems to apply - have been developed. In addition, ontology based repository structures and retrieval systems have been proposed to support ‘analogical thinking’ of designers. Nevertheless, these systematic approaches still restrict the candidates and inevitably lose potential biological systems relevant to the design project, due to the ‘physical relation’ biased problem and the ambiguity of the indexing mechanism of both current representation frameworks and retrieval systems. For example, the causality based support system known as a robust representation framework for a single biological system, stores information of a biological system only by its internal ‘physical relations’ and retrieves biological systetabms only by the physical relevance. However, from the perspective of ecological thinking, the further relatedness of ‘physical, biological, and ecological relations’ composes the holistic concept used to identify an organism in the flow of evolution because the ‘biological and ecological relations’ are also involved in the traits that designers may be interested in. Therefore, the supplementary information for ‘biological and ecological relations’ must be added to index the biological and environmental interactions, and to use the connectivity among entire organisms in the retrieval process. In this research, a causality based holistic representation framework for biological systems and an ‘all-connected’ ontology

关键词： Dynamic data structures   Hausdorff distance   Approximation algorithms  

摘要： We give a fully dynamic data structure for maintaining an approximation of the Hausdorff distance between two point sets in a constant dimension d, a standard problem in computational geometry. Our solution has an approximation factor of 1+epsilon for any constant epsilon > 0 and expected update time O (logU/loglogn), where U is the universe size, and n is the number of the points. The result of the paper greatly improves over the previous exact method, which required O (n(5/6)polylogn) time and worked only in a semi-online setting. The model of computation is the word RAM model. (C) 2016 Elsevier B.V. All rights reserved.
