Adaptive control of a flexible continuous structure is investigated. The application is directed toward large sensor count and several actuator systems,(multiple input / multiple output (MIMO) control. Conventional large channel count control applications involve complicated techniques to determine the proper order of the model and the dominant modes to be controlled. Using spatial filtering to...

Nonlinear static analysis is a validated tool for the seismic evaluation of existing and new structures, specifically reinforced concrete buildings. In order to assess performance frames designed according Venezuelan code, configurations low-, medium-, high-rise buildings are subjected 20 different load patterns considering nonlinear behavior FEMA P695. A total 140 frame models were analyzed us...

The paper presents a numerical study for the seismic assessment of the St James Church in Christchurch, New Zealand affected by the recent 2011 earthquake and subsequent aftershocks. The structural behavior of the Church has been evaluated using the finite element modelling technique, in which the nonlinear behavior of masonry has been taken into account by proper constitutive assumptions. Two ...

Assessing the structural capacity of an irregular structure requires appropriate and robust representation analytical model. Conventional procedures are flawed because they lack reversal effects higher modes. Therefore, more have been tested to accurately capture building-type structures. Some these may be classified as adaptive pushover techniques in which lateral load vector is revised instan...

Modal parameter extraction of high speed shafts is of critical importance in mechanical design of turbo-pumps. Due to the complex geometry and peripheral components of turbo-pumps, difficulties can arise in determination of modal parameters. In this study, modal properties of a turbo-pump shaft, was studied by experimental modal analysis, and using different excitation techniques. An innovative...

This paper introduces a novel, computationally efficient, and practical atmospheric tomography wavefront control architecture with separate minimum variance laser and natural guide star mode estimation. The architecture is applicable to all laser tomography systems, including multi conjugate adaptive optics (MCAO), laser tomography adaptive optics (LTAO), and multi object adaptive optics (MOAO)...

Supervised cross-modal hashing aims to embed the semantic correlations of heterogeneous modality data into binary hash codes with discriminative labels. It can support efficient large-scale retrieval due fast speed and low storage cost. However, existing methods equally handle tasks, simply learn same couple functions in a symmetric way. Under such circumstances, characteristics different tasks...
