We propose a new class of mappings, called Dynamic Limit Growth Indices, that are designed to measure the long-run performance of a nancial portfolio in discrete time setup. We study various important properties for this new class of measures, and in particular, we provide necessary and su cient condition for a Dynamic Limit Growth Index to be a dynamic assessment index. We also establish their...

Moving objects database (MOD) contains the information (locations and times) of moving objects, e.g., taxicabs, trucks, airplanes, polar bears, etc. This information continuously changes and thus needs to be updated frequently in order to maintain the accuracy and usefulness of the information. This paper presents a fuzzy-timing Petri net model for updating a MOD and a method for estimating the...

The immediate advantages of digital broadcast are the improvement in transmission quality and the increase in transmission capacity. But the major change for users will come from the future capacity of the video delivery chain to process this digital information to bu...

future increase of mobile communication subscribers will require a great capacity expansion of the cellular systems. in order to accommodate the increasing number of subscribers, the cell size will have to be much smaller than current size. therefore, it is predictable that the location updating and paging procedures will produce a major part of signaling traffic in these networks. this pape...
