With the increasing popularity of mobile computing devices, the need to access information in mobile environments has also grown rapidly. In order to support such mobile information accesses, location-based services and mobile information systems often rely on location-aware data management mechanisms like location-aware caching, data dissemination or prefetching. As we explain in this paper, t...

This chapter provides a discussion of the importance of the wider organisational context that the network administrator needs to deal with by describing how the organisational culture can impact on the degree to which security can be successfully maintained. It starts with an acknowledgement of the general clusters of factors that affect security (technology, processes, organisational, and huma...

we present a case report of acute spontaneous knee hemarthosis due to erosion of the nail through the knee joint capsule in a boy, seven months following retrograde flexible nailing for fractured femur. careful positioning of the location of the insertion site of flexible nails and proper nail tip management are important to avoid this rare late complication.

Location areas is a popular location management scheme in cellular networks. In the location areas scheme, a mobile terminal updates its location whenever it moves into a cell that belongs to a new location area. However, no matter how the location areas are designed, the ping-pong location update effect exists when a mobile terminal moves back and forth between two location areas. The paper de...

OBJECTIVE To find out the outcome of a cohort of women with pregnancy of unknown location presenting to a tertiary care hospital. METHODS The prospective study was conducted from January to December, 2011, at Early Pregnancy Assessment Unit, King Faisal Military Hospital, Khamis Mushait, Saudi Arabia. Data was collected for women with early pregnancy or with history of amenorrhoea, bleeding o...

Vehicular ad-hoc networks (VANETs) have been gained importance for the inter-vehicle communication that supports local communication between vehicles without any expensive infrastructure and considerable configuration efforts. How to provide light-weight and scalable location management service which facilitates geographic routing in VANETs remains a fundamental issue. In this paper we will pre...

Human resources development by means of training, education at universities and schools, and skill development within industry projects will be essential to foster product innovation within the African industry. It is expected that investments in Industrial Design Engineering (IDE) through educating engineering students and companies can contribute to the innovation capacity of African industry...

In this paper, we develop a uniform framework to provide a cost analysis of location update and search operations for a class of degradable location management algorithms in personal communication service (PCS) networks for tracking mobile users in the two-tier HLR (Home Location Register)–VLR (Visitor Location Register) structure. Depending on the algorithm employed, the PCS may be in a degrad...
