We derive uniform asymptotic expressions of some Abel sums appearing in some problems in coding theory and indicate the usefulness of these sums in other fields, like empirical processes, machine maintenance, analysis of algorithms, probabilistic number theory, queuing models, etc.

Dünya ekonomisi içerisinde deniz ulaşımının büyük etkisi olduğu yadsınamaz bir gerçektir. Deniz ulaşımı için gemiler ve limanlar kadar dar su yolları da önem arz etmektedir. Bu bağlamda yollarının dünya etkili olduğunu söylemek mümkündür. İstanbul Boğazı etken rol oynayan en önemlilerindendir. Her yolunda gibi Boğazı’nda beklemeler oluşabilmekte, meydana gelen ekonomisini etkilemektedir. çalışm...

Mobile ad-hoc networks pose real difficulty in finding the multihop shortest paths because of continuous changing positions of the nodes. Traditional ad-hoc routing protocols are proposed to find multi-hop routes based on shortest path routing algorithms, which cannot effectively adapt to time-varying radio links and network topologies of Ad-hoc networks. In this paper we proposed an enhanced r...

In this paper, we proposed a new multistage virtual shared memory model for cluster based parallel systems. This model can be expanded in hierarchical manner and covered many of the previous clusters of parallel system designs. Queuing theory and Jackson queuing networks are applied for constructing an analytical model. This model gives a closed-form solution for the system performance metrics,...

In this paper, we use both fuzzy optimization and normal simulation methods to solve fuzzy web planning model problems, which are queuing system problems for designing web servers. We apply fuzzy probabilities to the queuing system models with customers arrival rate λ and servers’ service rate μ, and then compute fuzzy system performance variables, including Utilization, Number (of requests) in...

To model the percentage change of blood oxygenation leveldependent (BOLD) signal and reaction time in a dual task, we propose a new mathematical modeling approach—a queuing network approach based on queuing network theory of human performance (Liu, 1996, 1997) and current discoveries in neuroimage studies. This approach includes a queuing network architecture representing the information proces...

ISSN 0085-7130 ©Telenor ASA 2007 Background Humans have practised gambling at all times. The archaeologists have made excavations in prehistoric sites and found large numbers of roughly dice-shaped bones. Different types of games, sports events, other types of events and gambling are connected because it has always been challenging to make bets on different outcomes of a game. Experiences and s...
