in the field of health losses resulting from failure to establish the facilities in a suitable location and the required number, beyond the cost and quality of service will result in an increase in mortality and the spread of diseases. so the facility location models have special importance in this area. in this paper, a successively inclusive hierarchical model for location of health centers i...

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...

Location-based social networks have attracted increasing users in recent years. Human movements and mobility patterns have a high degree of freedom and provide us with a lot of trajectory to understand the activity of users. In this paper, we present a user preferences and time sensitive recommender systems that offer an appropriate venue for a user when he appears in a special time at a partic...

Previous research has shown spontaneous location processing when location is not a task relevant feature and when a target is presented together with distractors. The present study investigates whether such processing can occur in the absence of distractor inhibition, and whether there is a processing asymmetry between location and an object feature. The results show that not all features are c...

Mobile device location information based services are one of the key drivers in Telecommunication market today. The current development of mobile device location based service solutions is focusing on a development of a particular services, but there is nearly no effort to build a framework that does not focus on a particular location information based service, but instead, provides developers ...

Location-aware services are a promising way of exploiting the special possibilities created by ubiquitous mobile devices and wireless communication. Advanced location-aware applications will require highly accurate information about the geographic location of mobile objects and functionality that goes beyond simply querying the user's position, for example determining all mobile objects inside ...

The new EU Directive 2002/58/EC has introduced with its Art. 9 special protection for location data other than traffic data. In this paper, we argue that also location data within traffic data can contain sensitive information about the ”relative positioning” and ”co-located displacements” of mobile nodes and thus also requires special protection. After a brief introduction to how mobility is s...

Location Based Services are a key driver in today's telecom market, even if the power of Location Based Services is not nearly exhausted in nowadays telecom systems. To build intuitive Location Based Services for mobile handsets one success factor is to cover a broad range of mobile handsets available on the market and to make the services context aware. Within the EUREKA project MyMobileWeb we...
