New Aggregation Algorithm for Tandem queue with Finite Buffers
김종환,Hur, Sung Kwan,徐承祿 大邱大學校附設 基礎科學硏究所 1991 基礎科學硏究 Vol.8 No.-
We consider a two-stage fmite tandem queueing system with Poisson arrivals and negative exponential service times. The customer who has completed his service at the first station has to go directlty to the second station. If the queue of the second station is full at the moment of the service completion of the customer at the first station, then the customer receives, another service at the first station. This is repeated until the customer completes a service at the first station at the moment that the second station is not fulL The problem of calculating the steady-state probabilities of this queueing system by the ordinary balance equations is time consuming. We develop an efficient algorithm to obtain the steady-state probabilities that utilize the two-way state aggregation techniques.

Of more than 30 varieties of zeolite group minerals, 7 varieties, mordenite, clinoptilolite, natrolite laumontite, stilbite, stellerite and chabazite are identified in Korea, whereas mordenite and clinoptilolite occur in Miocene sediments of small Yonil tertiary basin, east coast of Korea. The basin consists of three separate groups of sediments called Janggi, Gampo and Haseo, which are not correlated stratigraphyically yet. Zeolite occurs alternating with montmorillonite layers in Nuldaeri, Yongdongri and Haseori tuffs of Jahanggi, Gampo and Haseo Groups respectively. Zeolite was formed by diagenesis. of acidic volcanic tuffs.

Electrophoretic analysis has been used frequently to quantify genetic variability in many organisms. Isozyme variation between species of Pleuroceridae was analyzed by an electrophoretic technique. Pleuroceridae is consisted of two genus (Semisulcospira and Koreanomelania) and each genus is consisted of six species and three species, respectively. Among the Pleuroceridae, two genus and six species were analyzed. Each species of Pleuroceridae was collected in Nam-hangang and Kumgang. In SDS-PAGE patterns there are no distinctive differences among species. But in isozyme analysis using 7 isozymes (Esterase, Acid phosphatase, Alkaline phosphatase, Malate dehydrogenase, Alcohol dehydrogenase, Catalase, Peroxidase) of them. Semisulcospira libertina and S. coreana are the most highly related (0.86). S. gottschei is the least lowly related (0.44). Koreanomelania globus (0.62) is more related than S. tegulata (0.52) but less related than S. forticosta (0.67). The order of similarity relationship from S. libertina is S. coreana, S. forticosta, K. globus, S. tegulata and S. gottschei.
