A Message Broadcast Model for Train-to-Train Communication Network

2014
The railway safety requires that the communication network provides a sufficiently reliable transmission of control message. Though the Communication Based Train Control (CBTC) system is applied, there are still some railway accidents. This paper concentrates on a novel train-to-train communication network, proposes the scheme of message-broadcasting ...

Efficient Communications in Training Large Scale Neural Networks

Proceedings of the on Thematic Workshops of ACM Multimedia 2017, 2017
We consider the problem of how to reduce the cost of communication that is required for the parallel training of a neural network. The state-of-the-art method, Bulk Synchronous Parallel Stochastic Gradient Descent (BSP-SGD), requires many collective communication operations, like broadcasts of parameters or reductions for partial gradient aggregations,

Training Community Members for Action: Washington's Action Training Network

Journal of Health and Human Services Administration, 2002
The Children's Alliance in Washington State has established an ambi-tious goal of building the “Children's Action Network” (Network), a statewide network of children's advocates who regularly take action to inform public policy related to children and families. There are cur-rently about 3,000 members in the Network.

A bandwidth allocation strategy for train-to-ground communication networks

2014 IEEE 25th Annual International Symposium on Personal, Indoor, and Mobile Radio Communication (PIMRC), 2014
This paper formulates the bandwidth allocation problem in train-to-ground wireless communication networks in operational process of trains. It is shown that the Nash Bargaining game provides an Asymmetric Nash Bargaining Solution which is fair to bandwidth allocation problems in different services.

Ethernet Extensions for Train Communication Network

2014
The Train Communication Network (TCN) represents a fieldbus, which is used in railway vehicles. This established fieldbus has been standardized as an IEC standard by an international alliance of railway manufacturers. Ethernet protocols are structured in a layered and modular way.

Slave node architecture for train communications networks

2000 26th Annual Conference of the IEEE Industrial Electronics Society. IECON 2000. 2000 IEEE International Conference on Industrial Electronics, Control and Instrumentation. 21st Century Technologies and Industrial Opportunities (Cat. No.00CH37141), 2002
In this paper we present a new architecture for slave node of a train communication system based on the standard TCN (train communication network). This node is used to interconnect different electronic equipment based on the MVB (multifunction vehicle bus).

A top-down design for the train communication network

IEEE International Conference on Industrial Technology, 2003, 2004
A new electronic design for a TCN (train communication network) bus is presented in this paper. Based on top-down philosophy and focused on system on a chip strategies, various of its modules are expected to be reused in some other designs for complex communication circuits.

The Train Communication Network: Standardization goes aboard

2010 IEEE International Conference on Industrial Technology, 2010
Trains have evolved from being the first practical forms of mechanized land transport to the extremely complex and sophisticated transportation systems we currently use. Modern trains systematically incorporate more and more electronic equipment and consequently, nowadays multiple manufacturers and suppliers provide electronic systems for this well ...

Implementation of Train Communication Network for Korean High Speed Train (KHST)

IFAC Proceedings Volumes, 1999
Abstract This paper describes the efforts to implement TCN(train communication network) standardized by IEC for the Korean high speed train. The performance is measured and the problem of worst case communication latency not in data link layer but application layer is showed.
