Fuzzy risk analysis of a modern γ-ray industrial irradiator.
Fuzzy fault tree analyses were used to investigate accident scenarios that involve radiological exposure to operators working in industrial γ-ray irradiation facilities. The HEART method, a first generation human reliability analysis method, was used to evaluate the probability of a...

Improved automatic tuning of PID controller for stable processes
This paper presents an improved automatic tuning method for stable processes using a modified relay in the presence of static load disturbances and measurement noise. The modified relay consists of a standard relay in series with a PI controller of unity proportional gain. The integral time constant...
Ecological risks of an old wood impregnation mill: application of the Triad approach.
Although many studies deal with the distribution and mobility of chromated copper arsenate (CCA) metals in soil, the ecotoxicity of CCA-contaminated soils is rarely studied. The Triad approach was applied to determine the ecological risks posed by a CCA mixture at a decommissioned wood impregnation...
Open innovation networks between academia and industry: an imperative for breakthrough therapies.
Optimization of biobleaching of paper pulp in an expanded bed bioreactor with immobilized alkali stable xylanase by using response surface m...
Purified alkali stable xylanase from Aspergillus fischeri was immobilized on polystyrene beads using diazotization method. An expanded bed bioreactor was developed with these immobilized beads to biobleach the paper pulp in continuous mode. Response surface methodology was applied to optimize the bi...
Impact of species uncertainty perturbation on the solution stability of positive matrix factorization of atmospheric particulate matter data...
Statistical measures for evaluating the similarity of different source apportionment solutions are proposed. The sensitivity of positive matrix factorization to small perturbations in species measurement uncertainty estimates is examined using fine particulate matter measurements on organic carbon,...
Evidence and the industrialization of medicine.
We can see the twin changes of specialization, and the desire to codify practice such that those with different educational backgrounds can undertake a clinical role. Key to such change is the role played by evidence. Whereas once natural science was seen to determine clinical practice, this view is...
