Author:Fedotov, I; Fedotova, T; Shatalov, M; Tenkam, HMDate:Jul 2009The modelling of vibration problems is of great importance in engineering. A popular method of analysing such problems is the variational method. The simplest vibration model is represented using the example of a long rod. Two kinds of ...Read more
Author:Lebelo, RS; Fedotov, I; Shatalov, MDate:Sep 2008In this paper, the method of approximating solutions of partial differential equations with variable coefficients is studied. This is done by considering heat flow through a one-dimensional model with variable cross-sections. Two cases are ...Read more
