We find that telephone use has a positive and significant impact on income growth in African countries, all things equal. We also find that the demand for telep...
The demands to an IN database make it a distributed real-time heterogeneous database, where each of the nodes can be a parallel database. We will discuss the problems that the IN structure and its demands create, and how the current database research can fullll them. Our interests are in general solution level, logical data model, query languages, speed, and transaction handling and recovery. 1...
The traffic in telephone networks is analyzed in this paper. Unlike the classical traffic analysis where call blockings are due to the limited channel capacity, we consider here a more realistic cause for call blockings which is due to the way in which users are networked in a real-life human society. Furthermore, two kinds of user network, namely, the fully connected user network and the scale...

Each user has a fixed set of acquaintances with whom the user may communicate, and the number of acquaintances follows a power-law distribution. We sh...
