abstract: ballasted railway track are of the most common types of railway in our country. the aim of this paper is study of three-dimensional suitable model for railway ballasted track and dynamic analysis of that using numerical runge-kutta 4th order method. after the dynamic analysis is performed the responses related to railway components are determined. to analyze the effect of passing rail...

The Australian and New Zealand Collaborative Perfusion Registry (ANZCPR) tracks perfusion practices from the nine centers contributing to the collaborative dataset. It is unique in that data from the heart–lung machine, monitors, and the electronic perfusion records are able to be imported into the dataset. This allows many physiological parameters to be reported, including oxygen delivery. Fig...

This paper presents a novel procedure for solving the equations system of the rotating crack model used for reinforced concrete. It is implemented in the programme NonOPt where it is used to optimise the reinforcement design of D regions. The procedure is based on solving explicit closed-form relations without the need to incrementally increase the applied loads. The solution procedure is based...

A scale-up design procedure, based on a new physical mass transfer (PMT) model, whichdescribes the performance, for aerobic rotating biological contactors (RBC’s) is developed. This scale-up procedure can be used to determine the disc surface area needed to prevent an oxygen limitation or to obtain a specific degree of treatment. In contrast to the empirical, and most previous RBC performance m...

The paper estimates the effects of a simpler and faster criminal procedure on the duration of criminal cases and the probabilities that the defendant is charged and convicted. I exploit a criminal procedure reform in the Czech Republic as a quasi-natural experiment. The reform allowed petty offenses to be prosecuted via a simplified (fast-track) procedure. The share of cases actually prosecuted...

Ride comfort and safety of vehicles can be increased by active suspension systems. A problem is the detection of disturbances which can generally not be measured until they impact the chassis. Provided guidance and disturbance are known in advance, a controller can use this information to achieve considerably improved behavior. This paper presents an approach in which railway vehicles coupled i...

The possibility of a three-dimensional visualisation/reconstruction of tracks in nuclear emulsion films using X-ray imaging is described in this paper. The feasibility of the technique is established with experimental results.
