The results of the analysis quality indicators proposed control systems for electric drive DMZ ore yard with rheostatic tilt speed control, using alternative system "thyristor converter - DC motor" and "frequency induction motor", by studying transients these software product Matlab. It is established that parameters are not inferior to even slightly exceed it, in particular, range technologica...

Purpose: To determine resource rational allocation in the management of technique that specializes intra-terminal moving, to develop dispatching method for container flow. Methods: The work applies materials from open sources. Systematic approach is applied designing system terminal technique. Results: Method flow at has been developed, features combining conversion processes on basis prioritiz...

We investigate a question initiated in the work of Sibley and Wagon, who proved that 3 colors suffice to color any collection of 2D parallelograms glued edge-to-edge. Their proof relied on the existence of an “elbow” parallelogram. We explore the existence of analogous “corner” parallelepipeds in 3D objects, which would lead to 4-coloring. Our results are threefold. First, we refine the 2D proo...

Road rage and road traffic accidents increase the burden of morbidity and mortality in a population. A cross-sectional survey with convenience sampling was conducted among commercial vehicle drivers in Lahore, Pakistan (n = 901) to record their behaviours/experiences regarding road rage and road traffic accidents. Respondents were asked about incidents of shouting/cursing/rude gestures or threa...

This study investigates how shape optimisation affects the ultimate fatigue strength of a mechanical part. The mechanical part chosen for this investigation is an axle guard of running gear elements of the Hccrrs 2x2 axle car-carrying wagon. The static and fatigue strength analysis procedure according to the UIC 517 standard and numerical methods have been applied. Material properties were dete...

This paper succeeded in utilizing cellular automata (CA) model to simulate the process of the train operation under the four-aspect color light system and getting the nonperiodic diagram of the mixed passenger and freight tracks. Generally speaking, the concerned models could simulate well the situation of wagon in preventing trains from colliding when parking and restarting and of the real-tim...
