Meaningful quantification of data and structural uncertainties in conceptual rainfall-runoff modeling is a major scientific and engineering challenge. This paper focuses on the total predictive uncertainty and its decomposition into input and structural components under different inference scenarios. Several Bayesian inference schemes are investigated, differing in the treatment of rainfall and...

integration and coherence within a city’s physical structure have become an issue for towns and cities as theyrapidly expand, incorporate new elements, and undergo incessant changes. at present, we are facing an extensive accumulation of signs and traits in modern urban patterns; many unaccustomed to and incongruous are affecting the socio-cultural and physical characters of cities. here, we wi...

We first consider the following inverse eigenvalue problem: givenX ∈ Cn×m and a diagonal matrix Λ ∈ Cm×m, find n×nHermite-HamiltonmatricesK andM such thatKX MXΛ. We then consider an optimal approximation problem: given n × n Hermitian matrices Ka and Ma, find a solution K,M of the above inverse problem such that ‖K−Ka‖ ‖M−Ma‖ min. By using the MoorePenrose generalized inverse and the singular v...

Contact problems are frequent in structural analysis. They are characterized by inequality constraints such as non-interpenetration conditions, sign condition on the normal constraints, and an active contact, an area that is a priori unknown. Several approaches exist for solving the non linear equations issued from the finite element discretization of frictionless contact problems. In this work...

This paper presents a study on active detection of internal damage based on numerical analysis of vibration dynamics in composites. Damageinduced variations of dynamic parameters are investigated both numerically and experimentally. Finite element method (FEM) is used to compute the modal parameters of composites with or without damages. Natural frequency, modal displacement, modal strain and s...

Many combinatorial problems coming from the real world may not have a clear and well defined structure, typically being dirtied by side constraints, or being composed of two or more sub-problems, usually not disjoint. Such problems are not suitable to be solved with pure approaches based on a single programming paradigm, because a paradigm that can effectively face a problem characteristic may ...

Proteins usually consist of several structural domains which play an important role in the classification and analysis of them. As the number of known protein structures grows at an exponential rate, a computer-aided domain decomposition of proteins becomes desirable. We present three different decomposition methods in this report. They are based on a graph representation of the proteins. These...
