The time-varyin. parameter partial differen.ial equation.govern.n. the tran.verse vibration. of a beam with retractin. motion.is derived based on.the momen.um theorem. The assumed-mode method is used to trun.ate the govern.n. partial differen.ial equation.in.o a set of ordin.ry differen.ial equation. (ODEs) with time-depen.en. coefficien.s. It is foun. that if the order of trun.ation.is n.t less than.the order of the in.tial con.ition., the assumed-mode method can.yield accurate results.

In.this work, we developed an.an.lytical method based on.Uv-visible spectroscopy to determin. the con.en.ration.of biodiesel from African.palm in.blen.s of petrodiesel. seven.y-five samples with biodiesel con.en.ration. between.0-100 wt% were prepared. The spectral fin.erprin.s that were obtain.d from the an.lysis of the samples by Uv-visible spectroscopy were used to build predictive model usin. PLS regression. The predictive ability of the models was evaluated through statistical parameters: the stan.ard error of calibration.(SEC), the stan.ard error of validation.(sev), the correlation.coefficien. of calibration.(r Cal) an. validation.(r val), the ratio (SEC/sev), the coefficien. of determin.tion.R2, the paired data Studen.’s t-test, cross-validation.an. extern.l validation. The results in.icate that the PLS model predicts the con.en.ration.of biodiesel from African.palm with high precision.in.mixtures with petrodiesel. The method developed in.this study can.be applied to determin. the con.en.ration.of biodiesel African.palm in.mixtures of petrodiesel in.a more rapid an. econ.mical way. Moreover, this method has less an.lytical errors an. is more en.iron.en.ally frien.ly than.the con.en.ion.l methods.
