Numerical solution method for multi-term variable order fractional differential equations by shifted Chebyshev polynomials of the third kind

Multi-term variable-order fractional differential equations (VO-FDEs) are considered to be one E-stim Toys of the tools to illustrate the behavior of transient-regime real-life phenomena precisely.The analytical solutions of VO-FDEs are generally very hard to obtain.Therefore, in this study, an approximation method for the solution of multi-term VO

THE EFFECTS OF WATER CONTENT AND GRAIN SIZE ON THE CLOGGING AND ABRASIVITY OF FINE-GRAINED SOILS IN MECHANIZED EXCAVATION

Clogging during excavation is one of the common problems in mechanized excavation.Among the influential factors in clogging of the cutter head, we can mention the percentage of fine soil particles (under 200 mesh sieve), soil moisture, and soil type.In this study, to investigate the mechanism of tunnel excavation in the laboratory, a tunnel excavat
