Eiji Sensei, as he is affectionately known in Japan, is a simple and very charismatic man. I consider him a fatigueless scientist and a talented supporter who encourages others to devel...

the theoretical and experimental investigation on the thermo-mechanical properties of carbon nanotube (cnt) as reinforcer for oil and gas pipes has increasingly become a hot research area for many engineers and material scientists in recent years. this is mainly due to the advent of the new composite material systems that exhibit exotic material and mechanical properties as compared to the trad...

We present Tanaka’s prolongation procedure for filtered structures on manifolds discovered in [Tanaka N., J. Math. Kyoto. Univ. 10 (1970), 1–82] in a spirit of Singer– Sternberg’s description of the prolongation of usual G-structures [Singer I.M., Sternberg S., J. Analyse Math. 15 (1965), 1–114; Sternberg S., Prentice-Hall, Inc., Englewood Cliffs, N.J., 1964]. This approach gives a transparent ...
