Robust bootstrap procedures for the chain-ladder method [PDF]

, 2017
Insurers are faced with the challenge of estimating the future reserves needed to handle historic and outstanding claims that are not fully settled. A well-known and widely used technique is the chain-ladder method, which is a deterministic algorithm. To

Parametric Compact Thermal Models of Power LEDs

Energies, 2019
Light-emitting diodes are nowadays the most dynamically developing type of light sources. Considering that temperature is the main factor affecting the electrical and lighting parameters of these devices, thermal models are essential subcomponents of the

Quantum Monte Carlo diagonalization for many-fermion systems [PDF]

, 2007
In this study we present an optimization method based on the quantum Monte Carlo diagonalization for many-fermion systems. Using the Hubbard-Stratonovich transformation, employed to decompose the interactions in terms of auxiliary fields, we expand the ...

Quantum magnetism in the stripe phase: bond- versus site order [PDF]

, 1998
It is argued that the spin dynamics in the charge-ordered stripe phase might be revealing with regards to the nature of the anomalous spin dynamics in cuprate superconductors.

Superlight small bipolarons from realistic long-range Coulomb and Fr\"ohlich interactions [PDF]

, 2012
We report analytical and numerical results on the two-particle states of the polaronic t-Jp model derived recently with realistic Coulomb and electron-phonon (Frohlich) interactions in doped polar insulators.

Optimal Method for Catastrophic Faults Diagnosis in RC Ladder Network [PDF]

Advances in Power Electronics, 2016
The RC ladder network has been analyzed for various catastrophic fault detection using minimal number of measurements. Generally, electronic circuit testing procedure is very exhaustive and includes higher cost; the presented approach will save fault diagnosis time. It is not possible to analyze the big RC ladder network to give the good fault coverage,

Photoemission Spectra in t-J Ladders with Two Legs

, 1996
Photoemission spectra for the isotropic two-leg t-J ladder are calculated at various hole-doping levels using exact diagonalization techniques. Low-energy sharp features caused by short-range antiferromagnetic correlations are observed at finite doping ...

On the confinement of spinons in the $CP^{M-1}$ model

, 1995
We use the $1/M$ expansion for the $CP^{M-1}$ model to study the long-distance behaviour of the staggered spin susceptibility in the commensurate, two-dimensional quantum antiferromagnet at finite temperature.
