Digital filtering of band-limited signals using Periodic Nonuniform Sampling [PDF]

, 2008
We examine the problem of digital filtering of band-limited signals by means of a linear digital filter with one or more stopbands. The main target of the study is to filter the signals using lower than Landau sampling rates, where the Landau rate is ...

Noniterative DOA Estimation Algorithms of Noncircular Signals in Nonuniform Noise Environment

IEEE Access, 2020
In this paper, two noniterative direction-of-arrival (DOA) estimation algorithms of noncircular signals in nonuniform noise environment are proposed. Different from the mainstream nonuniform iterative algorithm, the algorithms we proposed in this paper ...

Finite Element Analysis on Stress of L80-1 Grade Casing under Complex Load

Shiyou jixie, 2021
In order to study the collapsing strength of oil casing under the condition of nonuniform distributed ground stress, taking the L80-1 grade casing as the research object, this paper built a casing-cement sheath-formation system model, then, applied ...

Adaptive Nonparametric Density Estimation with B-Spline Bases

Mathematics, 2023
Learning density estimation is important in probabilistic modeling and reasoning with uncertainty. Since B-spline basis functions are piecewise polynomials with local support, density estimation with B-splines shows its advantages when intensive ...

Experimental characterization of emittance growth induced by the nonuniform transverse laser distribution in a photoinjector

Physical Review Special Topics. Accelerators and Beams, 2002
The emittance of a high-brightness electron beam from a photoinjector is affected by the transverse and longitudinal distributions of the laser beam illuminating the cathode.

Acoustic Improvement of Stator–Rotor Interaction with Nonuniform Trailing Edge Blowing

Applied Sciences, 2018
The results of unsteady-flow simulations and experiments are discussed to investigate active noise-reduction effects on the stator–rotor interaction in a single-stage low-speed compressor with nonuniform trailing edge blowing.

Nonuniform bribery

International Joint Conference on Autonomous Agents and Multiagent Systems, 2008
We study the concept of bribery in the situation where voters are willing to change their votes as we ask them, but where their prices depend on the nature of the change we request. Our model is an extension of the one of Faliszewski et al. [9], where each voter has a single price for any change we may ask for.
