Scientists mapped the seismic time series into networks by considering geographical location of events as nodes and establishing links between with different rules. Applying successive defined laws to construct data, a variety features earthquake are detected (scale-free small-world structures). Network construction models had changed in detail optimize performance verification minimum size for...

one of the main challenges in wireless sensor network is energy problem and life cycle of nodes in networks. several methods can be used for increasing life cycle of nodes. one of these methods is load balancing in nodes while transmitting data from source to destination. directed diffusion algorithm is one of declared methods in wireless sensor networks which is data-oriented algorithm. direct...

The health sector, a foremost service sector in Nigeria, faces a number of challenges; primarily, the persistent under-funding of the health sector by the Nigerian government as evidence reveals low allocations to the health sector and poor health system performance which are reflected in key health indices of the country.Notwithstanding, there is evidence that the private sector could be a key...
