Membrane systems (P systems) are computational devices inspired from cell functioning, [8]. For this reason, it is important to introduce, in the P systems area, instruments to handle the imprecision that arises from (our) partial knowledge of many cellular phenomena. We present two possible ways to tackle imprecision in P systems. A first way consists in handling imprecision by using known mat...

This paper proposes a method to generate trajectories that are optimal with respect multiple objectives and robust against epistemic uncertainty. Epistemic uncertainty is modelled probability boxes optimised the lower expectations on cost functions constraint satisfaction. The an approach calculation of expectation using Bernstein polynomials, efficient many-objective optimisation trajectories....

OBJECTIVES To evaluate the performance of automated leucocyte (white blood cell; WBC) counting by comparison with manual counting. METHODS The number of WBC was determined in heparinized synovial fluid samples by the use of (i) a standard urine cytometer (Kova) and a microscope (reference method) and (ii) a haematology analyser (Sysmex XE-2100; WBC/BASO and DIFF channels). Imprecision within ...

An evaluation of the Technicon Axon analyser was carried out following the guidelines of the 'Sociedad Española de Química Clínica' and the European Committee for Clinical Laboratory Standards.A photometric study revealed acceptable results at both 340 nm and 404 nm. Inaccuracy and imprecision were lower at 404 nm than at 340 nm, although poor dispersion was found at both wavelengths, even at l...
