Thinning and conditioning of the Circular Unitary Ensemble [PDF]
, 2016 We apply the operation of random independent thinning on the eigenvalues of $n\times n$ Haar distributed unitary random matrices. We study gap probabilities for the thinned eigenvalues, and we study the statistics of the eigenvalues of random unitary ...

Application of an RBF blending interpolation method to problems with shocks
Computer Assisted Methods in Engineering and Science, 2017 Radial basis functions (RBF) have become an area of research in recent years, especially in the use of solving partial differential equations (PDE). Radial basis functions have an impressive capability in interpolating scattered data, even for data with

Mathematics, 2022 The temperature of indoor spaces is at the core of highly relevant topics such as comfort, productivity and health. In conditioned spaces, this temperature is determined by thermostat preferences, but there is a lack of understanding of this phenomenon ...

Condition Numbers of Gaussian Random Matrices [PDF]
SIAM Journal on Matrix Analysis and Applications, 2005 Let $G_{m \times n}$ be an $m \times n$ real random matrix whose elements are independent and identically distributed standard normal random variables, and let $κ_2(G_{m \times n})$ be the 2-norm condition number of $G_{m \times n}$. We prove that, for any $m \geq 2$, $n \geq 2$ and $x \geq |n-m|+1$, $κ_2(G_{m \times n})$ satisfies $ \frac{1}{\sqrt{2π}}

Predisposal conditioning, treatment, and performance assessment of radioactive waste streams
EPJ Nuclear Sciences & Technologies, 2022 Before the final disposal of radioactive wastes, various processes can be implemented to optimise the waste form. This can include different chemical and physical treatments, such as thermal treatment for waste reduction, waste conditioning for ...

Condition Numbers of Random Triangular Matrices [PDF]
SIAM Journal on Matrix Analysis and Applications, 1998 It is shown that the 2-norm condition number of a lower triangular matrix of dimension \(n\), whose entries come from an independent normal variable of mean 0 and variance 1, grows exponentially with \(n\). This is in striking contrast to the linear growth of the condition number of random dense matrices.

The impact of using reconditioned correlated observation‐error covariance matrices in the Met Office 1D‐Var system [PDF]
Quarterly Journal of the Royal Meteorological Society, 2019 Recent developments in numerical weather prediction have led to the use of correlated observation‐error covariance (OEC) information in data assimilation and forecasting systems.

Path-Wise Attention Memory Network for Visual Question Answering
Mathematics, 2022 Visual question answering (VQA) is regarded as a multi-modal fine-grained feature fusion task, which requires the construction of multi-level and omnidirectional relations between nodes.
