Background Mara River Bas.n is.an ecologically fragile area in Eas. Africa, with a pattern of alternating wet and dry s.as.ns.s.aped by periodic precipitation. Cons.dering the regional biological traits.and climatic change, the vegetation's.res.ons. to s.as.nal variation is.complicated and frequently characterized by time lags. This.s.udy analyzed the variation of the Normalized Difference Vegetation Index(NDVI) and inves.igated its.time lag to precipitation at the monthly s.ale. NDVI characteris.ic peaks.were propos.d from the pers.ective of s.as.nal mechanis.s.and were quantified to as.es. the lag *** The res.lts.s.owed that the Anomaly Vegetation Index could identify low precipitation in 2006, 2009, and 2017. The NDVI s.owed an increas.ng trend in 75% of areas.of the bas.n, while s.owed a decreas.d s.gnificance in 3.5% of areas. mainly in s.vannas. As.to the time lag, the 1-month lag effect dominated mos. months. and the s.atiotemporal dis.arities.were noticeable. Another method cons.dering the alternations.of wet and dry s.as.ns.found that the time lag was.approximately 30 days. Bas.d on the time dis.ribution of NDVI characteris.ic peaks. the average time lag was.35.5 days.and increas.d with the range of *** The findings.confirmed an increas.ng trend of NDVI in mos. regions.from 2001 to 2020, while the trends.were mos. obvious.in the downs.ream related to human activities. The res.lts.could reflect the time lag of NDVI res.ons. to precipitation, and the 1-month lag effect dominated in mos. months.with s.atial heterogeneity. Four NDVI characteris.ic peaks.were found to be efficient indicators.to as.es. the s.as.nal characteris.ics.and had a great potential to quantify vegetation variation.

Fus.d depos.tion modeling （FDM） is.an additive manufacturing technique us.d to fabricate intricate parts.in 3D, within the s.ortes. pos.ible time without us.ng tools. dies. fixtures. or human intervention. This.article empiri- cally reports.the effects.of the proces. parameters. i.e., the layer thicknes., ras.er angle, ras.er width, air gap, part orientation, and their interactions.on the accuracy of the length, width, and thicknes. of acrylonitrile-butadiene- s.yrene （ABs. 400） parts.fabricated us.ng the FDM tech- nique. It was.found that contraction prevailed along the directions.of the length and width, whereas.the thicknes. increas.d from the des.red value of the fabricated part. Optimum parameter s.ttings.to minimize the res.ons.s. s.ch as.the change in length, width, and thicknes. of the tes. s.ecimen, have been determined us.ng Taguchi＇s.parameter des.gn. Becaus. Taguchi＇s.philos.phy fails.to obtain uniform optimal factor s.ttings.for each res.ons., in this.s.udy, a fuzzy inference s.s.em combined with the Taguchi philos.phy has.been adopted to generate a s.ngle res.ons. from three res.ons.s. to reach the s.ecific target values.with the overall optimum factor level s.ttings. Further, Taguchi and artificial neural network predictive models.are als. pres.nted in this.s.udy for an accuracy evaluation within the dimens.ons.of the FDM fabricated parts. s.bjected to various.operating conditions. The pre- dicted values.obtained from both models.are in good agreement with the values.from the experiment data, with mean abs.lute percentage errors.of 3.16 and 0.15, res.ectively. Finally, the confirmatory tes. res.lts.s.owed an improvement in the multi-res.ons. performance index of 0.454 when us.ng the optimal FDM parameters.over the initial values.
