This paper introduces a simple diesel train energy consumption model that calculates the instantaneous using vehicle operational input variables, including speed, acceleration, and roadway grade, which can be easily obtained from global positioning system (GPS) loggers. The was tested against real-world data produced an error of −1.33% for all errors ranging −12.4% to +8.0% four datasets amount...

q uality of working life (qowl) is the attitudes of employees towards their job, especially their work outcomes including job satisfaction, mental health, and safety which directly influence organizational outcomes. therefore, the aim of the present study was to evaluate train drivers' qowl and determine its influencing factors. in this descriptive-analytical and cross-sectional study, qowl was...

background and purpose: social accountability, a concept which is in the focal attention more than ever, is to provide service in the field of medical sciences. we aimed to identify the educational challenges to train accountable graduates in the medical education system to meet social needs. methods: this study was conducted by qualitative content analysis using in-depth semi-structured interv...

Recently, the SPIKE-distance has been proposed as a parameter-free and timescale-independent measure of spike train synchrony. This measure is time resolved since it relies on instantaneous estimates of spike train dissimilarity. However, its original definition led to spuriously high instantaneous values for eventlike firing patterns. Here we present a substantial improvement of this measure t...

The research described in this paper was motivated by the idea to process purposefully given spike-trains using a cellular automaton (CA). CAs have three attractive features, namely massive parallelism, locality of cellular interactions, and simplicity of basic components (cells). However, the difficulty of designing a CA for a specific behavior causes limited interest in this computational par...

The paper discusses the development of an IBM PC based tool, for calculating train braking distances for various train classes on a rail network. There is discussion on current industry practice and the limitations of that practice, the concept of the tool itself, including the assumptions made, the strategy adopted to minimise the risk of incorrect calculations, and the results of adopting tha...
