A product limit estimator is suggested for the transition probabilities of a non-homogeneous Markov chain with finitely many states. The estimator is expressed as a product integral and its properties ...
q-analogue non-homogeneous wave equations are solved by a Duhamel solution strategy using constructions with q-analogue Fourier multipliers to compensate for the dependence of the analogue ...
Quantitative Micro-XRF analysis incorporates data across the whole irradiated and detected sample area. The quantification method requires a homogeneous sample to properly determine its composition.
