this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...

In this paper, we investigate a residual-based posteriori error estimates for the hp finite element approximation of general optimal control problems governed by bilinear elliptic equations. By using the hp discontinuous Galerkin finite element approximation for the control and the hp finite element approximation for both the state and the co-state, we derive a posteriori upper error bounds for...

The paper is devoted to the study of an approximation process of time optimal control for fractional evolution systems in Banach spaces. We firstly convert time optimal control problem into Meyer problem. By virtue of the properties of the family of solution operators given by us, the existence of optimal controls for Meyer problem is proved. Secondly, we construct a sequence of Meyer problems ...

Principal component analysis (PCA) has been widely used in analyzing high-dimensional data. It converts a set of observed data points possibly correlated variables into linearly uncorrelated via an orthogonal transformation. To handle streaming and reduce the complexities PCA, (subspace) online PCA iterations were proposed to iteratively update transformation by taking one point at time. Existi...

The paper is devoted to an emerging trend in control—a machine learning control. Despite the popularity of idea learning, there are various interpretations this concept, and urgent need for its strict mathematical formalization. An attempt formalize concept presented paper. concepts unknown function, work area, training set introduced, a formulation problem presented. Based on formulation, cont...
