Geografiske forskjeller i uføres dødelighet: Levekår, seleksjon, sosial avstand?
Geografiske forskjeller i uføres dødelighet: Levekår, seleksjon, sosial avstand? De uføretrygdedes overdødelighet er et sosialpolitisk problem, og helsesvikten som grunnga trygdingen forklarer ikke fullt ut den høye dødeligheten.

An Overview of Interrater Agreement on Likert Scales for Researchers and Practitioners
Applications of interrater agreement (IRA) statistics for Likert scales are plentiful in research and practice. IRA may be implicated in job analysis, performance appraisal, panel interviews, and any other approach to gathering systematic observations ...

Optimization Methods to Reduce Capacitor Stress in Modular Multilevel Converters
Modular multilevel converters consist of many capacitor half-bridge or full-bridge converter cells. Stresses on the capacitors result from peak capacitor voltage, capacitor voltage ripple and current ripple.

Multilevel Monte Carlo methods for ensemble variational data assimilation [PDF]
Ensemble variational data assimilation relies on ensembles of forecasts to estimate the background error covariance matrix B. The ensemble can be provided by an ensemble of data assimilations (EDA), which runs independent perturbed data assimilation and ...

Multilevel Monte Carlo methods [PDF]
Monte Carlo methods are a very general and useful approach for the estimation of expectations arising from stochastic simulation. However, they can be computationally expensive, particularly when the cost of generating individual stochastic samples is very high, as in the case of stochastic PDEs.

A multilevel discontinuous Galerkin method [PDF]
With extended references to the major papers on the subject, this work analyzes mathematically multigrid techniques for two discontinuous Galerkin methods: one for elliptic problems and a second one for singular perturbed advection-diffusion problems. In the former case, the analysis predicts convergence rates of the multigrid method independent of the

Segmentation is one of the important steps for image analysis. Multilevel thresholding image segmentation was more popular in image segmentation. Otsu and Kapur based methods are most popular for multilevel threshold image segmentation.
