In this study, an investigation of long-term forecasts relating to the development of the transport sector in Poland is performed, including the ones by 2030 and 2050. Selected transport development forecasts from the perspective of the membership of Poland in the European Union are presented and most of all, from the perspective of national studies. The basement for the review was the prognosi...

Analytical solutions have been obtained for both conservative and non-conservative forms of one-dimensional transport and transport-dispersion equations applicable for pollution as a result of a non-conservative pollutant-disposal in an open channel with linear spatially varying transport velocity and nonlinear spatially varying dispersion coefficient on account of a steady unpolluted lateral i...

This paper describes the optimization of dimensions individual injection mold runner system plastic part used as frame for various devices in transport means. Nowadays, great emphasis is placed on production time and finances associated with design production. As a result, simulations are being employed increasingly. aims to describe optimum size shape sprues runners required proper filling sim...
