Virtual sensors, or soft sensors, have greatly contributed to the evolution of the sensing
systems in industry. The soft sensors are process models having three fundamental …

State estimators, including observers and Bayesian filters, are a class of model-based
algorithms for estimating variables in a dynamical system given the sensor measurements of …

Polymer extrusion, in which a polymer is melted and conveyed to a mould or die, forms the
basis of most polymer processing techniques. Extruders frequently run at non-optimised …

Melt viscosity is regarded as a key quality indicator of the polymer melt in polymer extrusion
processes. However, limitations such as disturbances to the melt flow and measurement …

Since the early 2010s, after decades of premature excitement and disillusionment, the field
of artificial intelligence (AI) is experiencing exponential growth, with massive real-world …

In this study, the experiments of gas‐assisted extrusion (GAE) for molten polypropylene
were carried out under different gas pressures, the different extrudate deformations and …
