The influence of external field on the lubricity of mineral oil for railway transport

MATEC Web of Conferences, 2017
The use of mineral oil is associated with its gradual operational degradation caused by its natural aging and contamination with various impurities. As the concentration of impurities increases, the number of active surface molecules which determine the ...

Optimal Union-Find in Constraint Handling Rules

, 2004
Constraint Handling Rules (CHR) is a committed-choice rule-based language that was originally intended for writing constraint solvers. In this paper we show that it is also possible to write the classic union-find algorithm and variants in CHR.

Research of the strength of the bearing structure of the flat wagon body from round pipes during transportation on the railway ferry

MATEC Web of Conferences, 2018
The dynamic loading of the bearing structure of the flat wagon from round pipes was investigated during transportation on the railway ferry. The main types of movements of the railway ferry with wagons located on its decks are taken into account.

Handling congestion in crowd motion modeling [PDF]

, 2010
We address here the issue of congestion in the modeling of crowd motion, in the non-smooth framework: contacts between people are not anticipated and avoided, they actually occur, and they are explicitly taken into account in the model.
