✦ Synopsis

A personal computer program has been developed for use in the interactive analysis of positron lifetime spectra with the aid of a graphic display. The multi-exponential function model is used to fit a spectrum by the linear least-squares method. The spectrum displayed on the screen is altered simultaneously as the lifetime components are stripped one by one from the longest=lived to the shortest. The merit of this code is that it provides the user with a visual feedback at any stage of the analysis. Moreover, the obtained model parameters of the spectrum can be used as initial estimates for the POSITRONFIT program used for final analysis.

Generally speaking, the small car is less safe than the standard car, so more study of the conditions for safety in a small car is needed. We use a scale model, because the experiment is simple and inexpensive. Deceleration of the car and occupant in the small car were obtained by the scale model du
