Abstract: Abstract Full waveform inversion is a highly nonlinear inverse problem . Without an accurate initial model, it is difficult to obtain a global optimal solution because of cycle-skipping. In this paper we combine the Nth-order… read more here.

Abstract: Affect is integral to most decisions involving temptation. For instance, people may have difficulty saving for a house because they keep spending money on enjoyable, but more immediate items and events (e.g., fancy dinners). Little… read more here.

DOI: 10.1049/el.2018.6630
Abstract: A graphical control system design approach is proposed in this Letter considering time delay margin and time-integral performance criterion. For two free design parameters, time delay margin boundaries are plotted into 2D parameter plane by… read more here.

DOI: 10.1080/00207721.2020.1815893
Abstract: This manuscript introduces the design of a controller that ensures predefined-time convergence for a class of second-order systems. In contrast to finite- and fixed-time controllers, predefined-time schemes allow to prescribe a bound for the convergence… read more here.

DOI: 10.36660/abc.20190243
Abstract: Background Echocardiography is essential for the diagnosis and quantification of aortic regurgitation (AR). Velocity-time integral (VTI) of AR flow could be related to AR severity. Objective This study aims to assess whether VTI is an… read more here.
