Rational Arithmetic Mathematica Functions to Evaluate the Two-Sided One Sample K-S Cumulative Sampling Distribution [PDF]

open access: yesJournal of Statistical Software, 2007
One of the most widely used goodness-of-fit tests is the two-sided one sample Kolmogorov-Smirnov (K-S) test which has been implemented by many computer statistical software packages.

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 ...

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

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.

Probing Reactivity with External Forces: The Case of Nitroacetamides in Water

open access: yesMolecules, 2023
Many computational methods have been applied to interpret and predict changes in reactivity by slight modifications of a given molecular scaffold. We describe a novel and simple method based on approximate density-functional theory of valence electrons ...

Fiber integration on the Demailly tower [PDF]

open access: yes, 2015
The goal of this work is to provide a fiber integration formula on the Demailly tower, that avoids step-by-step elimination of horizontal cohomology classes, and that yields computational effectivity.
