polylactic acid based biodegradable nanocomposites reinforced with acetylated nanocellulose were fabricated with solution casting procedure. the nanocomposites were prepared by adding 1, 3 and 5% nanofiber loadings. the microstructure, physical, mechanical and thermal properties of the prepared nanocomposites were investigated. scanning electronic microscope (sem) analysis of the composites con...

This note presents the explicit form of the Laplace transform of the state transition matrix in the case of a system matrix being a companion matrix. Starting from this special case, we show how to compute the Laplace transform of the state transition matrix for any system matrix.1
