Kullback–Leibler Divergence as a Forecast Skill Score with Classic Reliability–Resolution–Uncertainty Decomposition

Steven Vincent Weijs, Nicolaas Cornelis van de Giesen

This paper presents a score that can be used for evaluating probabilistic forecasts of multicategory events. The score is a reinterpretation of the logarithmic score or ignorance score, now formulated as the relative entropy or Kullback–Leibler divergence ...

Transmission electron microscopy of Ca oxide nano- and microcrystals in alpha-tricalcium phosphate prepared by sintering of beta-tricalcium phosphate

Philippe Buffat, Elena Suvorova Buffat

Transmission electron microscopy (TEM) and X-ray diffraction (XRD) were used to study the porous and non-porous alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2), alpha-TCP) prepared through a sintering procedure at 1200-1400 degrees C of beta-tricalcium phos ...

An iterative domain decomposition algorithm for the grad(div) operator

Michel Deville, Etienne Ahusborde

This paper describes an iterative solution technique for partial differential equations involving the grad(div) operator, based on a domain decomposition. Iterations are performed to solve the solution on the interface. We identify the transmission relatio ...

Selective Formic Acid Decomposition for High-Pressure Hydrogen Generation: A Mechanistic Study

Paul Joseph Dyson, Gabor Laurenczy, Ning Yan, Céline Fellay

A homogenous catalytic system has been developed that efficiently and selectively decomposes formic acid into hydrogen and carbon dioxide. [Ru(H2O)6]2+, [Ru(H2O)6]3+ and RuCl3·xH2O are all excellent precatalysts in presence of TPPTS (TPPTS=meta-trisulfonat ...

Higher Order SVD Analysis for Dynamic Texture Synthesis

Sabine Süsstrunk, Luciano Sbaiz, Roberto Costantini

Videos representing flames, water, smoke, etc. are often defined as dynamic textures: "textures" because they are characterized by redundant repetition of a pattern and "dynamic" because this repetition is also in time and not only in space. Dynamic textur ...

Nitrous Oxide Decomposition on the Binuclear $\left$ Center in Fe-ZSM-5 Zeolite

The reaction mechanism for nitrous oxide (

{N}_{2}O

) direct decomposition into molecular nitrogen and oxygen was studied on binuclear iron sites in Fe-ZSM-5 zeolite using the density functional theory (DFT). Starting from the hydroxylated bi-iron complex ...

Carbon diffusion in CVD growth of carbon nanotubes on metal nanoparticles

Alfredo Pasquarello, Oleg Yazyev

Diffusion of carbon is the crucial step in chemical vapor deposition (CVD) growth of carbon nanotubes (CNTs) On metal nanoparticles. Using first principles techniques we model the binding and diffusion of carbon atoms and dimers on late transition (Ni, Pd, ...

Decomposition of copper concentrates at high-temperatures: An efficient method to remove volatile impurities

Christian Ludwig

The thermal decomposition of three synthetic copper sulfides (chalcocite (Cu2S), chalcopyrite (CuFeS2), and enargite (Cu3AsS4)) and two commercial copper concentrates has been studied on a thermobalance (T = 1173-1773 K) and an imaging furnace (T approxima ...

An analytic finite capacity queueing network model capturing blocking, congestion and spillbacks

Michel Bierlaire, Carolina Osorio Pizano

Analytic queueing network models often assume infinite capacity for all queues. For real systems this infinite capacity assumption does not hold, but is often maintained due to the difficulty of grasping the between-queue correlation structure present in f ...
