Finite element models of electromagnetic scattering/radiation problems involve absorbing boundaries for the computational domain truncation. Model order reduction based on eigenspace projection for such systems, invariably, has to deal with nonlinear eigenvalue problems. For small systems, the eigenspaces can be extracted using linearization techniques. However, the linearized system is atleast double...
Model order reduction (MOR) based on Krylov subspaces generated by matching Taylor series coefficients (moment matching) can not be applied to the finite element models of plane wave scattering problems. This paper proposes an extension of the Krylov subspaces to rectify the problem. The proposed technique displays good accuracy in a band of interest. The reduction in the computational cost and its...
Intermittent hardware faults are bursts of errors that last from a few CPU cycles to a few seconds. Recent studies have shown that intermittent fault rates are increasing due to technology scaling and are likely to be a significant concern in future systems. We study the impact of intermittent hardware faults in programs. A simulation-based fault-injection campaign shows that the majority of the intermittent...
Intermittent hardware faults are bursts of errors that last from a few CPU cycles to a few seconds. They are caused by process variations, circuit wear-out, and temperature, clock or voltage fluctuations. Recent studies show that intermittent fault rates are increasing due to technology scaling and are likely to be a significant concern in future systems. We study the propagation of intermittent faults...
A state-feedback controller was designed to simulate the Starling response of the heart in a mock circulatory system (MCS). The controller drives a voice coil actuator (VCA) to follow a reference volume, and thus generate the desired chamber pressure, by using position and speed feedbacks. The reference volume was adjusted according to the maximum ventricular elastance (Emax), end-systolic ventricular...
This paper addresses the problem of solving finite word-length (bit-vector) arithmetic with applications to equivalence verification of arithmetic datapaths. Arithmetic datapath designs perform a sequence of add, mult, shift, compare, concatenate, extract, etc., operations over bit-vectors. We show that such arithmetic operations can be modeled, as constraints, using a system of polynomial functions...
