This book presents the essential role of Mathematical Modeling and Computational Methods in representing physical phenomena mathematically, focusing on the significance of the I-function.

Prof. Vinod Prasad Saxena completed his M.Sc. in 1966 with distinction from Jiwaji University Gwalior, Madhya Pradesh. Four years afterwards he earned a Ph.D. for his research contribution entitled "Integral Transforms and Their Technical Application". At the postdoctoral level, he worked as CSIR senior Research Fellow and postdoctoral research fellow at SATI, Vidisha and M.A. College of Technology Bhopal from May 1969 to July 1971. Besides, Dr. V. P. Saxena was a visiting scientist at the University of Cambridge, England. He was also a visiting scientist in 1978 under the British Council UGC (INDIA) Exchange of Young Scientists Programme and worked under Sri James Hill, Professor of LUC Asian University. Besides being a professor, he was Dean, Faculty of Science, Jiwaji University, Gwalior from 1980 to 1986 and again from 1990 to 1992. Dr. V. P. Saxena took over as emergency Vice Chancellor, Jiwaji University on August 9, 2000. Dr. V. P. Saxena visited England, China, Singapore, Argentina, Turkey, Cyprus, Germany where he had delivered a series of lectures and presented scores of research papers on Mathematics and Engineering.
