The method of determination of optimum parameters of connecting curves on marshalling tracks, which insure the minimum distance from the first bunch switch to the seating of park car retarders is developed. This method can be applied in designing the plan... see more

The solution for a problem of determination of reducing the idle time wagon-hours for wagons in marshalling tracks, using the possible variants of work technology with the double-block train at a station of exchange groups, is proposed. The formulas for d... see more

For modeling of the trains accumulation process on marshalling tracks the special simulation model is designed. The model is used for study of the influence of specialization of marshalling tracks on duration of the operations for liquidation of «windows»... see more

The use of systems of the quasi–continuous adjusting the wagon speed on the marshalling tracks contributes to the improvement of indices of occupation quality of marshalling tracks with wagons. These indices characterize different sides of the occupation ... see more

AbstractThe 2019 Association for the Study of Australian Literature Conference took as its theme the subject of ‘dirt’, and inspired this paper which examines the ‘journeys into dirt’ by explorer figures in Patrick White’s 1957 novel Voss and Robyn Davids... see more

The Cape south coast of South Africa contains a wealth of Pleistocene vertebrate trace fossil sites in aeolianites and cemented foreshore deposits. Published studies have described mammal and avian tracksites identified along this coastline. We report her... see more

In Selective Laser Melting, the initial units produced are single tracks that overlap to create a single layer; from the sequence of layers, a 3D object is manufactured. The properties of the parts produced by SLM depend heavily on the properties of each ... see more

The stack pre-marshalling (SPM) problem is a complex combinatorial optimization problem which arises mainly within the rapidly growing field of container logistics. This paper proposes a heuristic-guided branch-and-bound (HGB&B) algorithm which can effect... see more
