Construction D-optimal designs of experiments for linear multiple regression with heteroscedastic observations

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In article the problem of construction exact D-optimal designs of experiments for linear multiple regression in a case when variance of errors of observations depend on a point in which is made is investigated.

Humidity Sensing by Chitosan-Coated Fibre Bragg Gratings (FBG)

open access: yesSensors, 2021
In this work, we report novel relative humidity sensors realized by functionalising fibre Bragg gratings with chitosan, a moisture-sensitive biopolymer never used before for this kind of fibre optic sensor.

Saturated buffer design flow and performance in Illinois

open access: yesJournal of Environmental Quality, 2022
AbstractThere are few peer‐reviewed studies documenting saturated buffer annual nitrate (NO3) removal or that have assessed the federal practice standard design criteria. Drainage flow, NO3, and dissolved reactive phosphorus (DRP) were monitored at three saturated buffers in Illinois, USA, for a combined 10 site‐years.

Numerical prediction of a flashing flow of saturated water at high pressure

open access: yesNuclear Engineering and Technology, 2018
Transient fluid velocity and pressure fields in a pressurized water reactor (PWR) steam generator (SG) secondary side during the blowdown period of a feedwater line break (FWLB) accident were numerically simulated employing the saturated water flashing ...

Dynamic Relative Output-Feedback Consensus for Multi-Agent Systems Subject to Actuator Saturation

open access: yesIEEE Access, 2020
This paper deals with the problem of leaderless consensus control for a class of non-introspective linear multi-agent systems (MASs) subject to input saturation and external disturbances.

Highly efficient libraries design for saturation mutagenesis

open access: yesSynthetic Biology, 2022
Abstract Saturation mutagenesis is a semi-rational approach for protein engineering where sites are saturated either entirely or partially to include amino acids of interest. We previously reported on a codon compression algorithm, where a set of minimal degenerate codons are selected according to user-defined parameters such as the ...
