Numerical simulations of a three-dimensional model of impingement and film cooling on a flat plate are presented and validated with the available experimental data. Four different turbulence models were utilized for simulation, in which SST  had the highest precision, resulting in less than 4% maximum error in temperature estimation. A simplified geometry with periodic boundary conditions is de...

State-of-the-art baggage handling systems transport luggage in an automated way using destination coded vehicles (DCVs). These vehicles transport the bags at high speeds on a “mini” railway network. In this paper we consider the problem of controlling the route of each DCV in the system. This is a nonlinear, nonconvex, mixed integer optimization problem. Nonlinear model predictive control (MPC)...

Time-Sensitive Networking (TSN) and Deterministic (DetNet) technologies are increasingly recognized as key levers of the future 5G transport networks (TNs) due to their capabilities for providing deterministic Quality-ofService enabling coexistence critical best-effort services. Additionally, they rely on programmable costeffective Ethernet-based forwarding planes. In this article, we address f...

The solutions used to solve bi-level congestion pricing problems are usually based on heuristic network optimization methods which may not be able to find the best solution for these type of problems. The application of meta-heuristic methods can be seen as viable alternative solutions but so far, it has not received enough attention by researchers in this field. Therefore, the objective of thi...

The paper describes two mathematical models of trade flows among the territories of a region or country. First model uses the approach of modeling the complex communication system to determine the most probable values of trade flows in a case of incomplete information about the system. Second one is based on multi-commodity network flow equilibrium approach. Transport costs between the territor...

In this paper, we consider a wideband CDMA network with arbitrary layout and variable MAC-rate assignments, which is connected to a traditional wired IP network. We show that by using an optimization framework, it is possible to construct an overlay system at the MAC and transport layers which regulates rates separately based on the congestion and interference constraints. These rates are coord...

This paper presents a novel method to partition urban space with respect to its mobility network rather than abstract administrative boundaries or simple grids. The main goal of our method is to support mobility infrastructure planning and optimization in an urban environment. To this end, our tessellation, which is based on constrained Voronoi tessellation, generates cells that are compact and...
