Hydrogen has been attracting attention as a fuel in the transportation sector to achieve carbon neutrality. storage liquid form is preferred locomotives, ships, drones, and aircraft, because these require high power but have limited space. However, hydrogen must be cryogenic state, wherein thermal insulation core problem. Inner materials, including glass bubbles, multi-layer (MLI), vacuum, vapo...

Nitrogen dioxide (NO2) is a gaseous air pollutant which primarily gets in the when fossil fuels such as coal, oil, gas or diesel are burned at high temperatures through industries, power plant, automobiles and locomotive. Continuous exposure to elevated concentration of NO2 may impose development asthma potentially increase susceptibility respiratory infections humans. The present study examine...

Purpose: The purpose of the present work is to test experimentally equalization method for outputs multi-cylinder diesel engine cylinders basing on energy minimization amplitude spectrum low-frequency band crankshaft instantaneous angular speed signal. Methods: uses methods digital signal processing, spectral analysis, differential calculus, multidimensional undifferentiated function optimizati...

Locomotive emissions from railroads can particularly impact air pollution, making it crucial to understand their impacts on human health and the environment develop strategies reduce them. The potential of drone technology equipped with a “sniffing” system for detecting pollution is promising be valuable tool assessing dynamic emissions. This research utilized sensor-equipped drones measure gas...

Five hundred and sixty British coalminers with relatively high or relatively low exposures to oxides of nitrogen, based on measurements of concentrations of these gases at nine collieries over four years, and records of the men's places of work and colliery mining conditions over a total of eight years have been studied. Data on these men's respiratory symptoms and ventilatory capacity (FEV1), ...

An autonomous control methodology is proposed for locomotive agents to have lifelike personified behaviors. The control introduces a pattern generator that is constructed by connecting oscillators composed of mutually inhibited neurons. The rhythmic signal of the pattern generator drives a proportional derivative controller that determines the legs joint angles of a locomotive agent, and the si...

Fuel spillage during locomotive refueling is expensive, as is maintaining spill collection and containment systems, and waste treatment costs. The Association of American Railroads has developed the first standard for a locomotive refueling system for North American railroads. The locomotive fueling interface standard is an open, non-proprietary standard designed to prevent fuel spillage. Proto...
