On numerical methods for highly oscillatory problems in circuit simulation [PDF]
, 2009 We propose in this paper a novel technique for an efficient numerical approximation of systems of highly oscillatory ordinary differential equations. In particular, we consider electronic systems subject to modulated signals.

International Journal for Numerical Methods in Engineering, 2008 AbstractNowadays, most of the ordinary differential equations (ODEs) can be solved by modelica‐based approaches, such as Matlab/Simulink, Dymola and LabView, which use simulation technique (ST). However, these kinds of approaches restrict the users in the enforcement of conditions at any instant of the time domain.

IGA-based Multi-Index Stochastic Collocation for random PDEs on arbitrary domains
, 2019 This paper proposes an extension of the Multi-Index Stochastic Collocation (MISC) method for forward uncertainty quantification (UQ) problems in computational domains of shape other than a square or cube, by exploiting isogeometric analysis (IGA ...

Optimizing Detection Schemes for Broadband Pump-Probe Microscopy. [PDF]
Microsc Res TechSmall spot sizes and broadband spectral coverage create unusual noise challenges for broadband pump‐probe microscopy. Analysis of probe and detector noise characteristics can provide strategies for mitigating these challenges. ABSTRACT Although similar to more commonly implemented single wavelength approaches, broadband pump‐probe or transient ...

Real‐Time 3D Ultrasound Imaging with an Ultra‐Sparse, Low Power Architecture
Advanced Healthcare Materials, EarlyView.This article presents a novel, ultra‐sparse ultrasound architecture that paves the way for wearable real‐time 3D imaging. By integrating a unique convolutional array with chirped data acquisition, the system achieves high‐resolution volumetric scans at a fraction of the power and hardware complexity.

Design and Performance Analysis of Differential Chaos Shift Keying System With Dual-Index Modulation
IEEE Access, 2019 In order to sufficiently utilize the time slot resources of the recently proposed pulse-position-modulation differential chaos shift keying (PPM-DCSK), we apply dual-index modulation to differential chaos shift keying and then present two differential ...
