Mining Explosions

Mining explosions and railway transportation generally result repeated intermission vibrations (RIV). These vibrations, with relatively shorter duration and larger peak acceleration, often repeat several times in a day. A proper evaluation method of human response should consider both the non-stationary nature and the occurrence frequency of RIV. This result the evaluation process has some differences compared with that for ordinary stationary vibration. Current evaluation method for human vibration comfort is first reviewed in this paper. Then the vibration dose value (VDV) and frequency of vibration events are introduced to evaluate vibration comfort under RIV. At last part of the paper, two vibration cases, one for blasting and one for railway transportation, are analyzed to explain above evaluation process.

Heuristic evaluation is one of the most used techniques to evaluate the level of usability of a software product. In this research, we performed a comprehensive analysis of the recent studies which report the use of this method in the context of a software development process. The purpose was to identify the specific way in which each author performs this usability evaluation method, in order to propose a formal protocol. After an indeed examination of these studies, we have determined there are several differences in the way this technique is conducted according to the literature. There is no agreement about the number of inspectors that should participate, the usability principles that should be used, the profile of the specialists who must be part of the assessment team, or the evaluation process that should be followed. This work highlights the available settings and a detailed procedure to perform a heuristic evaluation in the domain of software products.
