Pyroelectric and dielectric properties of calcium-barium niobate single crystals

Autor: Malyshkina, O. V., Lisitsin, V. S., Dec, J., Łukasiewicz, T.

Influence of the calcium concentration on the pyroelectric and dielectric properties of CaxBa1-xNb2O6 (CBN) crystals in a wide temperature range was studied. It is shown that calcium content (x) has an influence on the Curie point position but has no

Report

Ferroelectric and dielectric characterization studies on relaxor- and ferroelectric-like strontium-barium niobates

Autor: Matyjasek, K., Dec, J., Miga, S., Lukasiewicz, T.

Publikováno v: Condens. Matter Phys., 2013, vol. 16, No. 3, 31701

Ferroelectric domain structure evolution induced by an external electric field was investigated by means of nematic liquid crystal (NLC) method in two strontium-barium niobate single crystals of nominal composition: Sr_{0.70}Ba_{0.30}Nb_{2}O_{6} (SBN

Probabilistic Deduction with Conditional Constraints over Basic Events

Autor: Lukasiewicz, T.

Publikováno v: Journal Of Artificial Intelligence Research, Volume 10, pages 199-241, 1999

We study the problem of probabilistic deduction with conditional constraints over basic events. We show that globally complete probabilistic deduction with conditional constraints over basic events is NP-hard. We then concentrate on the special case
