In this paper we consider a generalized class of location-allocation problems, in which N new facilities are to be located in the plane with respect to M objects. We assume each object to be associated with a non-negative convex cost function, specifying the expenses for serving the object from any location in the plane. For the resulting multi-dimensional mixed-integer optimization problem two...

Location-Dependent Information Services is an emerging class of application that allows new types of queries such as location-dependent queries and continuous queries. In these systems, data caching plays an important role in data management due to its ability to improve system performance and availability in case of disconnection. In mobile environment, cache management requires more than trad...

Effective location management is critical for future personal communication service (PCS) networks, which envision smaller cells comprising a vast number of mobile terminals. In this paper we present a dynamic location management scheme with personalized location areas. The proposed technology takes into account the mobility patterns of the individual users in the system. The continuous time Ma...

This paper proposes using data broadcasting to build urban intelligent information infrastructures. It presents a conceptual framework for integrating cellular network location management into geographical data broadcast to provide efficient location dependent services. Within the context of the proposed framework, the paper then discusses the four major research issues: generic and geographic ...

this paper illustrates the application of s-transform and continuous wavelet transform (cwt) for fault location in combined overhead line and cable distribution networks. the high frequency transient signals originated by faults are analyzed using s-transform and cwt. the s-transform is found to be applicable in transient based fault location in distribution networks. this technique is an expan...

In the past few years, continuous monitoring of spatial queries has received significant attention from the database research community. In this paper, we study the problem of continuous monitoring of reverse k nearest neighbor queries. Existing continuous reverse nearest neighbor monitoring techniques are sensitive towards objects and queries movement. For example, the results of a query are t...
