Factor Analysis for Spectral Estimation
Factor Analysis for Spectral Estimation
收藏 引用
International Conference on Sampling Theory and Applications
作者: Joakim Anden Amit Singer Program in Applied and Computational Mathematics Princeton University Department of Mathematics and Program in Applied and Computational Mathematics Princeton University
Power spectrum estimation is an important tool in many applications, such as the whitening of noise. The popular multitaper method enjoys significant success, but fails for short signals with few samples. We propose a... 详细信息

7th International Conference on Mathematical Methods for Curves and Surfaces
作者: Bela, Szilvia Juettler, Bert Doctoral Program in Computational Mathematics Austria Institute of Applied Geometry Johannes Kepler University Linz 4040 Altenberger Str. 69 Austria
We present an algorithm generating a collection of fat arcs which bound the zero set of a given bivariate polynomial in Bernstein-Bezier representation. We demonstrate the performance of the algorithm (in particular t... 详细信息

Can nonlinear dynamics elucidate mechanisms in ecology and epidemiology?
收藏 引用
Mathematical Medicine and Biology 1985年 第4期2卷 221-252页
作者: Schaffer, W.M. Department of Ecology and Evolutionary Biology University of Arizona United States Program in Applied Mathematics University of Arizona Tucson AZ 85721 United States
Using recently developed methods in nonlinear dynamics, two hypotheses often advanced to account for recurrent outbreaks of childhood diseases such as measles are investigated. The first, maintenance of otherwise damp...

Coarse-grained spectral projection: A deep learning assisted approach to quantum unitary dynamics
收藏 引用
Physical Review B 2021年 第2期103卷 024304-024304页
作者: Pinchen Xie Weinan E Department of Mathematics and Program in Applied and Computational Mathematics Princeton University New Jersey 08544 USA
We propose the coarse-grained spectral projection method (CGSP), a deep learning assisted approach for tackling quantum unitary dynamic problems with an emphasis on quench dynamics. We show that CGSP can extract spect... 详细信息

ISING-MODEL SIMULATIONS ON THE MANIFOLDS OF 2-DIMENSIONAL QUANTUM-GRAVITY
收藏 引用
MODERN PHYSICS LETTERS A 1991年 第17期6卷 1615-1628页
作者: AGISHTEIN, ME BAILLIE, CF Program in Applied and Computational Mathematics Princeton University Fine Hall Princeton NJ 08544-1000 USA Physics Department University of Colorado Boulder CO 80309 USA
The Ising model is stimulated on the manifolds of 2-dimensional quantum gravity, which are represented by fixed random triangulations (so-called quenched Ising model). Unlike the case of the Ising model on a dynamical...

Renormalization theory for eddy diffusivity in turbulent transport
收藏 引用
Physical Review Letters 1992年 第20期68卷 3028-3028页
作者: Marco Avellaneda Andrew J. Majda Department of Mathematics Program in Applied and Computational Mathematics Princeton University Princeton New Jersey 08544
We examine the derivation of eddy-diffusivity equations for transport of passive scalars in a turbulent velocity field. Our main contention is that, in the long-time–large-distance limit, the eddy-diffusivity equatio...

Master of Applied Science in Midwifery Program Poltekkes Kemenkes Semarang Indonesia Postgraduate Applied Science Midwifery Program Poltekkes Kemenkes Semarang Indonesia Departement of Physics Faculty of Science and Mathematics Universitas Diponegoro semarang Indonesia
Neonatal jaundice often occurs in newborns characterized by a yellow discoloration of the sclera and baby's skin due to high levels of bilirubin in the blood. The occurrence of jaundice needs done identified to th... 详细信息

作者: Deng, Y. Hu, Q. Chung, U.J. Chitu, A.M. Limanov, A.B. Im, James S. Program in Materials Science and Engineering Department of Applied Physics and Applied Mathematics Columbia University New York NY 10027 United States
We have investigated the solid nucleation mechanism in laser-quenched Si films on SiO2. Previously neglected experimental steps, consisting of BHF-etching and irradiation in vacuum, were implemented to reduce potentia... 详细信息
