Interaction between freshwater and seawater can significantly influence marine life and create important productive and dynamic natural habitats, such as estuaries. We study such processes and for this purpose we develop a new mathematical model with the system of coupled nonlinear conservation equations that govern the interaction of the two incompressible fluids with different properties.…

This paper deals with intermodal transportation of goods from Europe to the United States. The main objective is the development of a mathematical model called Transatlantic multi-mode container routing problem. It provides a tool for network optimization in transportation science. The developed model enables users to determine the optimal collaborative routing in a network system…

Market globalization has posed the problem of finding economical routes of product delivery one of which is via a system of intermodal motor traction. Currently, the automotive manufacturing plant KAMAZ supplies its products and accompanying servicing to countries in Europe, Asia, Africa and Latin America, and intends to extend the market. This study deals with…

The world is considering various solutions to reduce exhaust emissions, the use of alternative fuels and the development of more efficient marine engines. IMO the company gave guidance for future borders of individual exhaust components, taking into account a variety of applications and conditions for the operation of marine engines. Engine manufacturers have been forced…

The transport sector is the fastest growing consumer of energy and producer of greenhouse gases in the European Union. With new emission regulation these days the potential application for LNG are expanding. LNG provides a greener alternative to other fossil fuels, which can significantly contribute to improve European air quality and to reduce the existing…
