Development of Sewage Pumps with Numerical and Experimental Support

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2023
Especially in the field of sewage pumps, the design of radial impellers focuses not only on maximum efficiency but also on functionality in terms of susceptibility to clogging by fibrous media.

Directed transport in a classical lattice with a high-frequency driving [PDF]

open access: yes, 2007
We analyze the dynamics of a classical particle in a spatially periodic potential under the influence of a periodic in time uniform force. It was shown in [S.Flach, O.Yevtushenko, Y. Zolotaryuk, Phys. Rev. Lett. 84, 2358 (2000)] that despite zero average

Quantum and Classical Superballistic Transport in a Relativistic Kicked-Rotor System

open access: yes, 2014
As an unusual type of anomalous diffusion behavior, superballistic transport is not well known but has been experimentally simulated recently. Quantum superballistic transport models to date are mainly based on connected sublattices which are constructed

Neuronal network approach to study the operation of shuttle-service trains

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2023
Introduction. The authors study the section of the shuttle-service trains. Based on a detailed description and characterisation of the site, it is categorised as a man-machine and difficult-to-formalise system.

Analysis of Public Transport System, Hatay Example: Detection of Existing System [PDF]

open access: yes, 2018
Today, with the development of our cities, the population density has increased and therefore many problems have arisen due to the increase of the traffic density in the city and the existing transportation systems which were previously not planned with ...

Integrating Bayesian network and generalized raking for population synthesis in Greater Jakarta

open access: yesRegional Studies, Regional Science, 2019
Constructing agent data with detailed information on their sociodemographics is substantially important for agent-based modelling. However, to collect data about the whole population is not efficient, since it requires an expensive and time-consuming ...

Optimal transport over a linear dynamical system [PDF]

open access: yes, 2017
We consider the problem of steering an initial probability density for the state vector of a linear system to a final one, in finite time, using minimum energy control.

Mathematical modeling of fastening conditions in piggyback transport: ensuring safety and stability across different transport modes

open access: yesDiscover Applied Sciences
Ensuring cargo stability during piggyback transportation is crucial for maintaining safety and efficiency, especially in intermodal transport systems. This study focuses on developing a mathematical model to optimise the fastening methods for vehicles ...

SIMMAG3D as a tool for designing of storage facilities in 3D [PDF]

open access: yesArchives of Transport, 2017
Designing of storage facilities is an interdisciplinary process that requires consideration of technical, economic, social or environmental issues. Storage facilities, as a part of supply chain are designed to provide customers availability of goods at a
