Drought is one of the most important weather-induced phenomena which may have severe impacts on different areas such as agriculture, economy, energy production, and society. A number of drought indices have been introduced and used in various countries to date. In the current study, four meteorological drought indices including Percent of Normal Precipitation Index (PNPI), Standard Index of Ann...

A primary challenge to implementing structural health monitoring techniques on civil infrastructure is the differentiation of effects of environmental variables on the behaviour of structures from other causes of structural change. Data from the Z24 Bridge recorded over the course of nearly a year are analysed in this paper. Covariance-driven Stochastic Subspace Identification is applied to the...

We show that surface normal information allows to significantly improve the accuracy of a spatio-temporal multi-view reconstruction. On one hand, normal information can improve the quality of photometric matching scores. On the other hand, the same normal information can be employed to drive an adaptive anisotropic surface regularization process which better preserves fine details and elongated...

Abstract. A binary code is said to be a disjunctive list-decoding sL-code, s ≥ 1, L ≥ 1, (briefly, LD sL-code) if the code is identified by the incidence matrix of a family of finite sets in which the union of any s sets can cover not more than L− 1 other sets of the family. In this paper, we introduce a natural probabilistic generalization of LD sL-code when the code is said to be an almost di...

Abstract. Simulating numerically the sound radiation of a rolling tire requires the solution of a very large and sparse gyroscopic eigenvalue problem. Taking advantage of the automated multi– level substructuring (AMLS) method it can be projected to a much smaller gyroscopic problem, the solution of which however is still quite costly since the eigenmodes are non–real and complex arithmetic is ...

The parametrization of linear one-dimensional optical systems using the so-called Twiss parameters, b, a, and f, has been well established for some time [1]. The extension to two dimensions involves identifying the normal modes by transforming the full turn 4 3 4 transfer matrix to block diagonal form [2]. The system is then parametrized using the six Twiss parameters for both normal modes and ...

We compute the Weyl anomaly for an abelian Wilson surface by using a regularization that respects the gauge invariance. We then study the loop space on which lives a one-form connection. We restrict ourselves to the subsector consisting of only concentrical circular loops, and derive a Maxwell type action on this restricted loop space.
