We have developed a parser which takes as input a file containing the analytical expression of one or more formulas and ranges for each unknown in the formula and returns an interval evaluation of the formula. We describe the use of this parser for solving robotics problems and, in a more general co

โฆ Synopsis
In recent years, ground vibrations have become an important issue due to the growing awareness of the society about environmental living conditions. In this way, vibrations caused by trains running near houses or workplaces are considered disturbing for residents. Within this framework, this paper presents a procedure to estimate the vibration path caused by the passing of a train. In order to achieve this, the equations which describe the physical phenomenon are set in the frequency and wavenumber domain and solved by using the Fourier Transform. The obtained analytical solution is transformed back into the time and space domain by means of the Fourier series. The obtained theoretical results are compared with experimental measurements carried out in the Madrid-Barcelona High Speed Line in order to analyse the performance of this procedure.
