Analysis of a class of distributed queues with application [PDF]
, 1988 Recently we have developed a class of media access control algorithms for different types of Local Area Networks. A common feature of these LAN algorithms is that they represent various strategies by which the processors in the LAN can simulate the ...

Overhead Line Mechanics Taking the Influence of Wind into Account [PDF]
, 2017 This paper deals with problems of overhead line motion. The line model is based on a dynamic description of a catenary curve. The benefits of dynamic modeling in this field are decrypted, and there is an explanation of one of the models that is used. The
