A formula for computation of the real stability radius [PDF]

open access: greenAutomatica, 1995
The authors present a method for approximation of the maximal perturbations of a real matrix. Its eigenvalues have to stay in a prescribed area in the complex plane. Such a measure of robustness of the eigenvalue clustering property is called a real stability radius.

Quantum computing of semiclassical formulas [PDF]

open access: yesPhysical Review E, 2008
We show that semiclassical formulas such as the Gutzwiller trace formula can be implemented on a quantum computer more efficiently than on a classical device. We give explicit quantum algorithms which yield quantum observables from classical trajectories, and which alternatively test the semiclassical approximation by computing classical actions from ...

Efficient computation of the Zassenhaus formula [PDF]

open access: yesComputer Physics Communications, 2012
A new recursive procedure to compute the Zassenhaus formula up to high order is presented, providing each exponent in the factorization directly as a linear combination of independent commutators and thus containing the minimum number of terms. The recursion can be easily implemented in a symbolic algebra package and requires much less computational ...

Optimizing 3D Convolution Kernels on Stereo Matching for Resource Efficient Computations

open access: yesSensors, 2021
Despite recent stereo matching algorithms achieving significant results on public benchmarks, the problem of requiring heavy computation remains unsolved. Most works focus on designing an architecture to reduce the computational complexity, while we take

Log BPS numbers of log Calabi-Yau surfaces [PDF]

open access: yes, 2020
Let $(S,E)$ be a log Calabi-Yau surface pair with $E$ a smooth divisor. We define new conjecturally integer-valued counts of $\mathbb{A}^1$-curves in $(S,E)$. These log BPS numbers are derived from genus 0 log Gromov-Witten invariants of maximal tangency

Carrier Dynamics in High-Efficiency Blue GaN Light-Emitting Diodes Under Different Bias Currents and Temperatures

open access: yesIEEE Photonics Journal, 2012
Distinct temperature-dependent dynamic behaviors of GaN-based blue light-emitting diodes (LEDs) are observed by use of the very-fast electrical-optical pump-probe technique.
