On a duality principle in processes of servicing machines with double control
This paper examines a doubly controlled process of servicing machines. The classical system treated by Takács is equipped with m+1 unreliable machines served by one repairman. In the present modification of this model, the ...
On a multi-channel queue with state dependent input flow and interruptions
This paper deals with a multi-channel queueing system with a finite waiting room but without losses. The latter is achieved by a temporary interruption of the input flow activity until the waiting room is ready to place a ...
On a multi-channel transportation loss system with controlled input and controlled service
A multi-channel loss queueing system is investigated. The input stream is a controlled point process. The service in each of m parallel channels depends on the state of the system at certain moments of time when input and ...
ON FINITE ELEMENT METHODS FOR THE EULER-POISSON-DARBOUX EQUATION.
We deal primarily with the derivation of various convergence estimates for some semidiscrete and fully discrete procedures which might be used in the approximation of exact solutions of initial-boundary value problems with ...
Activity coefficient and the Einstein relation
A connection between the activity coefficient of current carriers and the Einstein relations is established by two methods, one based on normal semiconductor concepts and one based on irreversible thermodynamics. The ...
