CONSTRUCTION METHOD OF A-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2015
Here, we study the design in that we determine unknown measurements of p objects by used of n measurement operations. For that reason we consider the chemical balance weighing design under assumption that the measurement errors are uncorrelated and they ...

ON D-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2015
The paper deals with the problem of determining the chemical balance weighing designs satisfying the criterion of D-optimality under assumption that the measurement errors are equal correlated and they have the same variances.

Experimental Characterization and Population Balance Modelling of the Dense Silica Suspensions Aggregation Process. [PDF]

open access: yes, 2008
Concentrated suspensions of nanoparticles subjected to transport or shear forces are commonly encountered in many processes where particles are likely to undergo processes of aggregation and fragmentation under physico-chemical interactions and ...

The Michaelis-Menten-Stueckelberg Theorem

open access: yesEntropy, 2011
We study chemical reactions with complex mechanisms under two assumptions: (i) intermediates are present in small amounts (this is the quasi-steady-state hypothesis or QSS) and (ii) they are in equilibrium relations with substrates (this is the ...

Use of chemical totalizer of radiation in energy balance measurements

open access: yesSilva Fennica, 1978
The investigation is concerned with testing chemical totalizer of radiation (Frankfurt radiometer) for use in measuring the components of a simple energy balance (latent heat = net radiation – sensible heat) so as to gain an estimate for evaporation ...
