a Matlab Program for 1d strain rate inversion
Computers & Geosciences, 2010Co-Authors: Haibin Song, Lin Chen, Jiong Zhang, Changyu Zhao, Chongzhi DongAbstract:This paper presents a Matlab Program designed to invert 1D strain rate from subsidence data. In forward modeling, we use an implicit finite difference scheme to solve the heat conduction equation with an advective term. In the inversion, we adopt the Powell algorithm to continually search for the optimal values of strain rate until the fit, defined by the difference between the calculated subsidence and the observed subsidence, is satisfactory. Synthetic datasets are generated, and one of them is used to test the inversion algorithm. The results show that the calculated subsidence fit the theoretical subsidence quite well, and the inverted strain rate oscillates around the true value and is a good approximation to the original strain rate variation. The Program is applied to the northern continental margin of the South China Sea, and the inverted strain rate from WC1411 well reveals the multiple rifting events that occurred in this region. The inverted strain rate can be used to evaluate the stretching factor and provides constraints for dynamic modeling of lithospheric deformation.

APCCAS - A Matlab Program for Volterra distortion analysis in CMOS switched source follower
2012 IEEE Asia Pacific Conference on Circuits and Systems, 2012Co-Authors: Hailang Liang, Jin He, Cheng Wang, Mansun ChanAbstract:A Matlab Program for Volterra distortion analysis of ultra high speed weakly nonlinear circuit is presented. A Volterra series method and a nodal formulation are used in this Program. Approximate expressions for the transfer function, the harmonic equations and third-order intermodulation distortion equation are given respectively. Simulations based on a commercially available 65 nm CMOS process technology are performed with both the Matlab Program and the SpectreRF circuit simulator. It is shown that results obtained by the Matlab Program have a consistent match with those derived from SpectreRF simulator, whereas the overall computational efficiency has been improved.

ex stream a Matlab Program for calculating fluid flux through sediment water interfaces based on steady and transient temperature profiles
Computers & Geosciences, 2011Co-Authors: Travis Swanson, Bayani M CardenasAbstract:Temperature is a useful environmental tracer for quantifying movement and exchange of water and heat through and near sediment-water interfaces (SWI). Heat tracing involves analyzing temperature time series or profiles from temperature probes deployed in sediments. Ex-Stream is a Matlab Program that brings together two transient and two steady one-dimensional coupled heat and fluid flux analytical models. The Program includes a graphical user interface, a detailed user manual, and postprocessing capabilities that enable users to extract fluid fluxes from time-series temperature observations. Program output is written to comma-separated values files, displayed within the Matlab command window, and may be optionally plotted. The models that are integrated into Ex-Stream can be run collectively, allowing for direct comparison, or individually.
