The aims of our study were to examine whether a gravity-removal physical activity classification algorithm (GRPACA) is applicable for discrimination between nonlocomotive and locomotive activities for various physical activities (PAs) of children and to prove that this approach improves the estimation accuracy of a prediction model for children using an accelerometer. Japanese children (42 boys...

Hybrid electric propulsion, using batteries for energy storage, is making significant inroads into railway transportation because of its potential notable fuel savings and the related reductions in greenhouse gases emissions hybrid traction over non-electrified lines. Due to inherent complexity hybridized powertrains, combining different power conversions storage capabilities, corresponding ope...

Genetic screens have been widely applied to uncover genetic mechanisms of movement disorders. However, most screens rely on human observations of qualitative differences. Here we demonstrate the application of an automatic imaging system to conduct a quantitative screen for genes regulating the locomotive behavior in Caenorhabditis elegans. Two hundred twenty-seven neuronal signaling genes with...

The study is aimed at replacing outdated approaches in the organization of maintenance locomotive fleet. article presents a comparative analysis strategies for traction rolling stock. necessity introducing control over technical condition locomotives to ensure transition preventive system substantiated. Directions research - adjustment existing volumes and frequency repairs, introduction indivi...

Purpose: To develop methodology for determining the actual resistance of traction electric drive (TED) circuits a locomotive with power transmission and refined calculation voltage losses collector-brush apparatus according to microprocessor control system data. These data are necessary calculating characteristics as well its braking in modes. Methods: Methods machine theory, statistical proces...

Time-lapse videotape recordings of polymorphonuclear leukocytes (PMNs) from clot preparations were used to quantify the locomotive behavior of individual PMNs from normal subjects. Tracings derived from the videotapes allow one to quantify multiple parameters of the locomotive behavior of PMNs--direction, distance, rate, and angle of turn. The results obtained are reproducible from subject-to-s...

In today's design, system complexity and increasing demand for safer, more efficient and less costly systems have created new challenges in science and engineering. Locomotives are products which are designed according to market order and technical needs of customers. Accordingly, targets of companies, especially designers and manufacturers of locomotives, have always been on the path of progre...
