Genetic evaluation of daily gains of dual-purpose bulls using a random regression model
Czech Journal of Animal Science, 2008 Daily gains of 8 243 dual-purpose bulls from 100 to 400 days of age during the years 1971 to 2007 were analyzed by random regression models. Orthogonal Legendre polynomials (LP) of degree 4 were applied to daily gains calculated at 30-day intervals over ...

Assessment of collision-induced derailment of single wheelset on curved tracks by rail removing and lateral impact [PDF]
International Journal of Railway Research, 2022 Significant lateral and vertical impact forces can cause a derailment on the curved tracks. In this work, we try to indicate the similarities and differences between derailment modes on the curved track due to the lateral impact, considering the position

Influence of gauge width on rail side wear on track curves
Journal of Civil Engineering and Management, 2006 The main property of the railway system is infrastructure objects and rollingâ€stock. Holding any kind of a property requires huge expenses and renovation investments. Intensive wearing of the rails on the track curves is observed.
