We introduce a platform for the rapid prototyping of proactive locationbased service discovery, proactive location-based services are conceptualised along three broad categories: location-triggered services chain-triggered services, proximity-triggered services, and illustrated through a number of usage scenarios. We report on a workshop with designers and researchers in the area of location-ba...

Background Although proven feasible, rapid response services (RRSs) to support urgent decision and policymaking are still a fairly new and innovative strategy in several health systems, more especially in low-income countries. There are several information gaps about these RRSs that exist including the factors that make them work in different contexts and in addition what affects their uptake b...

background: identification of the effective factors in reducing response time in prehospital emergency medical service (ems) can assist in improving its services. this study aimed at reviewing the effect of applying global positioning system (gps) on response time of tehran ems ambulances. materials and methods: of 132 tehran ems stations, 24 ones were randomly selected, and relevant data, incl...

In this paper we describe how the contentionbased medium access mechanism of 802.11e, EDCA, can be enhanced in order to allow stations to reserve medium access for their real-time applications with QoS requirements. We present our proposed scheme, which is called EDCA with resource reservation (EDCA/RR), and describe how it can be extended in order to be used in wireless multi-hop networks. EDC...

Location based services (LBS) and applications have recently emerged as a significant application area. However, location based services and application could also benefit of the dimensions of the contextual data. MultiUser Publishing Environment (MUPE) has a built-in context mediation capability that allows the application developer to concentrate on using contextual data and thus enabling rap...
