Loan behavior modeling is crucial in financial engineering. In particular, predicting loan prepayment based on large-scale historical time series data of massive customers challenging. Existing approaches, such as logistic regression or nonparametric regression, could only model the direct relationship between features and prepayments. Motivated by extracting hidden states behavior, we propose smoothing spline state space (QuadS) a Markov with varying transition emission matrices modeled...
To attenuate ultra-low frequency waves in a rod, this study proposes new meta-rod with negative-stiffness springs attached to an external fixed supporting. We analytically derive the dispersion relation of and reveal its bandgap properties using transfer matrix method. Then we numerically develop finite-length model investigate wave attenuation behavior by finite element In particular, essential problem concerns how boundary spring influences is explored. By attaching supporting, can be...
The atmospheric fluorocarbon plasma is widely used in surface modification of polymers. Recently, the pulsed microwave Ar/CF4 jet proved to be a promising source with good performance. In this paper, discharge characteristics are studied systematically. morphologies, ionization processes, optical emission spectra, and electron densities obtained by digital camera, an intensified charge coupled device, fiber spectrometer, home-made Rayleigh scattering respectively. influences operation...
