As countries move towards malaria elimination, methods to identify infections among populations who do not seek treatment are required. Reactive case detection, whereby individuals living in close proximity to passively detected cases are screened and treated, is one approach being used by a number of countries including Swaziland. An outstanding issue is establishing the epidemiologically and ...

In this paper, a model is presented to locate ambulances, considering backup facility (to increase reliability) and the restriction of ambulance capacity. This model is designed for emergencies. In this model the covered demand for each demand point depends on the number of coverage times and the amount of demand. The demand amount and ambulance coverage radius are considered...

The blood supply chain as a part of healthcare systems play a substantial role in health improvement within societies, and blood supply for daily needs and especially in disasters is the challenges requiring more attention. This paper presents a fuzzy-stochastic mixed integer linear programming model to design blood supply chain network for disaster relief. To deal with the uncertainty in model...

The UGPL (unmanned Air Vehicle to ground path loss), a Matlab application, is used for Unmanned (UAV) communication channel calculations. It developed consider the different environment types and antenna loss. In addition, it considers effect of elevation angle on loss coverage application consists two sub-applications. first sub-application makes calculations under certain max allowable find o...

Wireless sensor networks are presently a growing area as they form a platform for many applications associated to surroundings monitoring, fitness and wellbeing, supervision and military surveillance. One of the major design aspects of Wireless Sensor Network (WSN) is the sensor node deployment strategy. The deployment strategy is vital because it can affect the performance of the network. A Gr...

Decentralized motion coordination for coverage optimization purposes in mobile sensor networks is the scope of this paper. Coordination is performed based on spatial Voronoi tessellation, while taking into consideration the limited sensing capabilities of the agents. Each node performs an independent optimization in order to increase network’s area coverage via its motion, while it attains info...

BACKGROUND AND PURPOSE The current self-initiated approach by which hospitals acquire Primary Stroke Center (PSC) certification provides insufficient coverage for large areas of the United States. An alternative, directed, algorithmic approach to determine near optimal locations of PSCs would be justified if it significantly improves coverage. METHODS Using geographic location-allocation mode...
