This paper presents the development of wavelet neural network (WNN) with an improved fruit fly optimization algorithm (IFOA) for the melt index prediction in the industrial propylene polymerization process. The structure, calculation, and prediction process of WNN are proposed, and the improved details of IFOA are introduced, which can enhance the searching efficiency and improve the searching quality over the traditional fruit fly optimization algorithm. Finally, the WNN-IFOA model can obtain the least predicting errors compared with other existing models and shows better generality for the online melt index prediction from the experimental results.

This article traces the development of the field of mutagenesis and its metamorphosis into the research area we now call genetic toxicology. In 1969, this transitional event led to the founding of the Environmental Mutagen Society (EMS). The charter of this new Society was to "encourage interest in and study of mutagens in the human environment, particularly as these may be of concern to public health." As the mutagenesis field unfolded and expanded, new wording appeared to better describe this evolving area of research. The term "genetic toxicology" was coined and became an important subspecialty of the broad area of toxicology. Genetic toxicology is now set for a thorough reappraisal of its methods, goals, and priorities to meet the challenges of the 21st Century. To better understand these challenges, we have revisited the primary goal that the EMS founders had in mind for the Society's main mission and objective, namely, the quantitative assessment of genetic (hereditary) risks to human populations exposed to environmental agents. We also have reflected upon some of the seminal events over the last 40 years that have influenced the advancement of the genetic toxicology discipline and the extent to which the Society's major goal and allied objectives have been achieved. Additionally, we have provided suggestions on how EMS can further advance the science of genetic toxicology in the postgenome era. Any oversight or failure to make proper acknowledgment of individuals, events, or the citation of relevant references in this article is unintentional.

“…Therefore if general analysis method is used, this will greatly depend on the experience [4,5]. The wavelet transform is being used in chemistry and its related domain in recent years [6][7][8][9][10][11]. Ehrentreich, F. pointed out that the wavelet transform has been established with the Fourier transform as a data-processing method in analytical chemistry [6].…”

Horizontal attenuation total reflection-Fourier transform infrared spectroscopy (HATR-FTIR) is usedto measure the FTIR of coat of good orange and rotten orange. Continuous wavelet transform (CWT) is used to decompose the FTIR of theirs. Three main scales are selected as the feature extracting space in the CWT domain. Three feature regions are determined at every spectra band at selected three scales in the CWT domain. Thus nine feature parameters form the feature vector. The feature vector is input to support vector machine (SVM) to train so as to accurately classify the good orange and rotten orange. 80 couples of FTIR are used to train and test the proposed method, where 60 couples of data are used as training samples and 20 couples of data are used as testing samples. Experimental results show that the accurate recognition rate between good orange and rotten orange is respectively 98.8% and 97.6% by using the proposed method.
