abstract: aqueous enzymatic extraction of oil from pistacia khinjuk was performed using cellulase. the central composite design was used to optimize the parameters that are significant to the process. the influence of three regressors on the percentage of oil recovery from seed was evaluated using second-order polynomial multiple regression model. analysis of variance showed a high coefficient ...

Abstract This paper proposes a data processing scheme for laser spot thermography (LST) applied nondestructive testing (NDT) of composite laminates. The LST involves recording multiple thermographic sequences, resulting in large amounts that have to be processed cumulatively evaluate the diagnostic information. demonstrates new based on parameterization and machine learning. approach allows ove...

Certain results of numerical simulations obtained by the use of the spectral finite element method in time domain are presented by the authors. They were selected in order to show the effectiveness of the spectral finite element method for investigation of problems associated with propagation of guided elastic waves in a wind turbine laminated composite blade. Results of these simulations were ...

The Thermographic Signal Reconstruction (TSR) technique, based on the logarithmic polynomial fitting of the temperature time-evolution, improves the efficiency of pulse-stimulated thermography. However, the non-destructive evaluation of the inspected structure requires the analysis of the full temperature-time sequence. This drawback impacts all transient thermal NDE method whatsoever. A new po...
