Studies of Thermally Unstable Accretion Disks around Black Holes with Adaptive Pseudo-Spectral Domain Decomposition Method I. Limit-Cycle Behavior in the Case of Moderate Viscosity

open access: yes, 2007
We present a numerical method for spatially 1.5-dimensional and time-dependent studies of accretion disks around black holes, that is originated from a combination of the standard pseudo-spectral method and the adaptive domain decomposition method ...

Design of Multi-Band Filters Using Parallel Connected Topology [PDF]

open access: yesRadioengineering, 2018
This paper presents the design of multi-band filters using parallel connected topology. The resonator in each branch is the dual-mode resonator which provides two resonant modes per passband for miniaturization.

Deep neural networks on graph signals for brain imaging analysis

open access: yes, 2017
Brain imaging data such as EEG or MEG are high-dimensional spatiotemporal data often degraded by complex, non-Gaussian noise. For reliable analysis of brain imaging data, it is important to extract discriminative, low-dimensional intrinsic representation

Synthesis of Phase-Correcting Elements Based on Band-Pass Filter and Their Application in Transmitarray Antenna

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника
Introduction. This paper presents a procedure for synthesis of phase-correcting elements (PCE) based on band-pass filter using specialized software developed for these purposes. The amplitude response of the synthesized PCE and LC-filters based on lumped

Solving, Estimating and Selecting Nonlinear Dynamic Economic Models without the Curse of Dimensionality [PDF]

open access: yes
A welfare analysis of a risky policy is impossible within a linear or linearized model and its certainty equivalence property. The presented algorithms are designed as a toolbox for a general model class. The computational challenges are considerable and
