Simulation plays an important r^ ole in stochastic geometry and related elds, because all but the simplest random set models tend to be intractable to analysis. Many simulation algorithms deliver (approximate) samples of such random set models, for example by simulating the equilibrium distribution of a Markov chain such as a spatial birth-and-death process. The samples usually fail to be exact...

by entering the era of information and communication and moving from manufacturing and industrial economy towards knowledge-based service economy; the competitive bases of businesses have changed from capital budgeting and tangible assets towards intangible assets and intellectual capital, including social and relational capitals. hence, over the past ages, organizations emphasize more on infor...

The utilization of VoIP (Voice over IP) in UMTS networks requires the establishment of adequated rules in order to maximize the efficiency of transmission over the air interface. Here we will describe a technique, based on the reduction of voice packet overhead, with the objective of minimizing the power expended during a typical conversation.

Existing microstructure literature cannot explain the empirical evidence that bid-ask spreads can decrease with information asymmetry and ignores either information asymmetry or inventory risks. We develop a market making model that highlights the asset pricing impact of market makers’ capability of making offsetting trades in markets where both information asymmetry and inventory risk are sign...

In this paper, a multicast scheme for UMTS which only requires insignificant modifications in the current UMTS network infrastructure is analyzed. We analytically present the multicast routing mechanism behind our scheme as well as the multicast group management functionality of it. Furthermore, we present an evaluation of our scheme in terms of its performance. The critical parameters for the ...

Sea surface reservoir ages must be known to establish a common chronological framework for marine, continental, and cryospheric paleoproxies, and are crucial for understanding ocean-continent climatic relationships and the paleoventilation of the ocean. Radiocarbon dates of planktonic foraminifera and tephra contemporaneously deposited over Mediterranean marine and terrestrial regions reveal th...
