Modern machine learning techniques have encouraged interest in the development of vehicle health monitoring systems that ensure secure and reliable operations of rail vehicles. In an earlier study, an energy-efficient data acquisition method was investigated to develop a monitoring system for railway applications using modern machine learning techniques, more specific classification algorithms. A suitable classifier was proposed for railway monitoring based on relative weighted performance metrics. To improve the performance of the existing approach, a rule-based learning method using statistical analysis has been proposed in this paper to select a unique classifier for the same application. This selected algorithm works more efficiently and improves the overall performance of the railway monitoring systems. This study has been conducted using six classifiers, namely REPTree, J48, Decision Stump, IBK, PART and OneR, with twenty-five datasets. The Waikato Environment for Knowledge Analysis (WEKA) learning tool has been used in this study to develop the prediction models.

Mobile technology is becoming increasingly widespread in museums and cultural heritage sites, and many institutions have already developed applications that can be downloaded on mobile phones. Amongst these, iPhone Applications are certainly the most popular. The research briefly presented here describes the phases of the development of an iPhone application to interactively present the story of the people and places depicted on the Summer War of Osaka byo̅bu (traditional Japanese wooden folding screens) currently displayed at Osaka Castle Museum, Osaka City, Japan. The iPhone application will also be integrated with the Tiled Display Wall system of the Knowledge Creating Communication Research Center of NICT (Kyoto) to test various interaction functionalities.

The calculation of short-circuit currents in DC auxiliary systems of power plants and substations is essential for design and application of distribution and protective devices used in these systems. Because of differences between DC and AC auxiliary systems, DC system protection designers should be take into account that important fact in calculation and dimensioning of DC auxiliary system. There are several mathematical models that are usually used for calculation of short-circuit currents in DC auxiliary system. In this paper, the authors performed short-circuit currents calculation for one real DC auxiliary system of power plant using three different, well-known, mathematical models. The results of calculations were compared with results given by testing of selectivity of DC auxiliary system on the site. Based on comparison results of different calculations and testing on the site conclusion related to choice one of three the most often used mathematical models as the most suitable has deduced.
