This paper introduces a new technique for location management in cellular networks. It avoids the recording of moving tracks of mobile subscribers. The described procedures are derived from the well known untraceable MIX network and the distributed storage of location information according to GSM networks. 1 Terminology The served area of a cellular radio network is usually divided into locatio...

Location management is an essential service in mobile networks. It provides mechanisms for recording and querying location of mobile units in the network. This is needed for establishing calls to mobile units. In PCS networks, location management protocols such as IS-41 and GSM use statically defined Registration Areas (RAs) with two-level hierarchy of location databases. In this paper, we prop...

The benefits of customer relationship strategies are well known and somewhat established nowadays. Customer loyalty emerges as the crucial glue in developing a relational approach. However, relational bonds, which relate to customer loyalty, have not yet been fully explored. Also, there is little research that takes into account the effect of service types on customer relationships and bonding....

Field normalized citation rates are well-established indicators for research performance from the broadest aggregation levels such as countries, down to institutes and research teams. When applied to still more specialized publication sets at the level of individual scientists, also a more accurate delimitation is required of the reference domain that provides the expectations to which a perfor...

blood supply chain management is one of the mainchallenges in healthcare system. optimal locationof blood donation camps is one of the key factors in optimizing the bloodsupply chain. disruption in location of blood donation camps because ofdisasters will have a negative impact on the entire supply chain. thispaper develops a generalized network optimization model for the complex supplychain of...

Distraction is a common method of pain control that is often found to be effective. However, it is still largely unexplored which components of distraction are responsible for its effects. This study investigated the role of the spatial location of task-relevant stimuli on the effectiveness of distraction. Two experiments were performed in which the spatial location of visual stimuli during noc...

Change point detection in sequences of functional data is examined where the functional observations are dependent. Of particular interest is the case where the change point is an epidemic change (a change occurs and then the observations return to baseline at a later time). The theoretical properties for various tests for at most one change and epidemic changes are derived with a special focus...
