This paper describes a comparative study of two feedback control methods for a microfluidic electroporation (EP) system. The regulation of the transmembrane voltage (Vm) and nano-electropore radius (r) of HeLa cells on a micro EP chip was achieved using a linear Proportional-Integral-Derivative (PID) Controller and also Model Predictive Controller (MPC) based on the critical electric field for single-cell...
When solving radiation and/or scattering problems, the Method of Moments can give wideband information by using a Model Based Parameter Estimation technique for the expansion coefficients. The parameters are obtained by computing the values of expansion coefficients and their frequency derivatives at a fixed center frequency. This requires computing the moment matrix and its frequency derivatives...
A set of general purpose two-dimensional single-field finite-difference time-domain updating equations for solving oblique incidence electromagnetic problems is derived. The traditional FDTD updating equations are based on Maxwell's curl equations whereas the single-field FDTD updating equations are based on the vector wave equation. Performance analyses of the single-field formulation in terms of...
The problem of wave reflection and transmission at the interface between an isotropic (air) medium and biaxially anisotropic medium is solved and analyzed. We observe behavior that differs from the typical behavior at an isotropic-isotropic interface. It is seen that rotating the permittivity tensor of the biaxial medium with respect to the reference coordinate system significantly affects the reflection...
A new method for finding all fractional-order (FO) proportional-integral-derivative (PID) controllers that stabilize a given system of integer or non-integer order is proposed. The stability boundaries of such FO PID controllers are calculated in the frequency domain and are given in terms of the proportional gain Kp, integral gain Ki, and derivative gain Kd. In this paper, they will be plotted on...
Petascale simulations are needed to understand the rupture and wave dynamics of the largest earthquakes at shaking frequencies required to engineer safe structures (> 1 Hz). Toward this goal, we have developed a highly scalable, parallel application (AWP-ODC) that has achieved “M8”: a full dynamical simulation of a magnitude-8 earthquake on the southern San Andreas fault up to 2 Hz. M8 was calculated...
Almost Regular Permutation (ARP) and Quadratic Permutation Polynomials (QPP) are two common types of inter-leavers for parallel turbo decoding. However, for a turbo decoder using such an interleaver, previous memory-mapping schemes are applicable only if, P, the number of processors used, divides L, the interleaver length, and P satisfies various other constraints. In this paper, we introduce a novel...
