Traction Force Microscopy in 3‐Dimensional Extracellular Matrix Networks

Current Protocols in Cell Biology, 2017
AbstractCell migration through a three‐dimensional (3‐D) matrix depends strongly on the ability of cells to generate traction forces. To overcome the steric hindrance of the matrix, cells need to generate sufficiently high traction forces but also need to distribute these forces spatially in a migration‐promoting way.

Traction Network Current Rate Changing Analysis

2018 19th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices (EDM), 2018
The parameters of transition processes characteristics could be defined on oscillogram data obtained by means of remote monitors access received from a power section. Also this data helps to analyze protection operation and adjust setpoints. The article is focused on current rate changing analysis at different traction network operation modes.

Traction control using artificial neural networks

2023
Modern traction control techniques manage driven wheel speed from data obtained through a small number of sensors from around an automobile. This data is then fed into an on-board computer that has been specially programmed to attempt to maximise driven wheel traction from its information base.

The Unbalanced Modes Analyze Of Traction Loads Network

2020 Ural Symposium on Biomedical Engineering, Radioelectronics and Information Technology (USBEREIT), 2020
Presently, it has been recognized that unbalanced modes of high-voltage networks occur quit often and adversely affect the electrical consumers and the technical-economic indicators of electric power systems. The adverse effect lies in the fact that under unbalance current, the transmission capacity of three-phase supply systems decreases, the ...

Diagnostics of Electrical Connections of Electric Traction Network

2020
Full-scale structural measurements of new and existing electric traction networks are becoming increasingly important because of the ever-increasing train speeds and associated effects. Higher speeds lead to increased loads and greater structural dynamic responses, increasing mechanical and electrical loads.

Mass transit power traction networks as communication channels

IEEE Journal on Selected Areas in Communications, 2006
The rapid progress of power line communications (PLC) for data transmission over electric power supply systems is now opening ways for special applications such as train automation in local transportation and mass transit (MT) systems. These DC-powered traction networks can be used as communication links between wayside equipment and the moving trains.

Power Quality Improvement in Traction Power Supply Networks

2013
AC railway traction loads are usually huge single phase loads. As a result, a significant amount of Negative Sequence Current (NSC) is injected into utility grid. Moreover, harmonics and consumption of reactive power are further power quality problems that the supply network is encountering.

Effects of the traction network voltage fluctuation on the permanent magnet synchronous traction drive system

2014 International Power Electronics and Application Conference and Exposition, 2014
In this paper, the mathematical model of the PMSM (permanent magnet synchronous motor) traction drive system is established. After the linearization of the model, the equation of state which takes the fluctuations of the DC traction voltage as input is deduced.
