Queue, queue, queue for care.

The cyclic queue and the tandem queue

We consider a closed queueing network, consisting of two FCFS single server queues in series: a queue with general service times and a queue with exponential service times. A fixed number N of customers cycles through this network. We determine the joint sojourn time distribution of a tagged customer in, first, the general queue and, then, the exponential queue. Subsequently, we indicate how th...

The Queue - Read Queue - WriteAsynchronous PRAM

This paper presents results for the queue-read, queue-write asynchronous parallel random access machine (qrqw asynchronous pram) model, which is the asynchronous variant of the qrqw pram model. The qrqw pram family of models, which was introduced earlier by the authors, permit concurrent reading and writing to shared memory locations, but each memory location is viewed as having a queue which c...

Roll the Dice

In the 2014 annual meeting of the Korean Society of Mathematical Biology, the managing editor proposed an interesting idea: viewing problematic gambling as a contagious disease [1]. One article was then submitted and enlisted in the June issue of this journal [2]. As part of our efforts to imprint a unique feature to the readers of biomedical journals by publishing at least one mathematical mod...

Investigation of the mechanical properties of cold roll welded Brass and IF steelproduced by cold roll bonding process

Cold roll bonding (CRB) is a solid state welding process, where the bonding is established by compressive plastic deformation of the metals. This process is applicable for a large number of materials. In addition, materials that cannot be bonded by traditional fusion-based processesmight be bonded by CRB process. In this research, cold roll welding of brass and IF steel was studied .The effects...
