The current growth in Internet services, mobile devices, and machine-to-machine (M2M) technologies is providing the building blocks for the Internet of Things (IoT) as it is being applied across all industry sectors. With ongoing proliferation of IoT applications, a new platform called Fog/edge computing, in addition to Cloud computing, is being developed to address requirements such as bandwidth,...
The Internet of things (IoT) is hailed as the next big phase in the evolution of the Internet. IoT devices are rapidly proliferating, owing to widespread adoption by industries in various sectors. Unlike security and privacy concerns, the energy consumption of the IoT and its applications has received little attention by the research community. This paper explores different options for deploying energy-efficient...
In this study, observations from a high-frequency radar (HFR) deployment are combined with numerical model simulations to investigate the relative contributions of surface current forcing. A tidal decomposition of the relevant datasets was applied by fitting the flow profile to a finite set of sinusoids at specific frequencies related to astronomical parameters. The resultant time-series pair comprised...
In this work we present a technique for the assimilation of ocean surface current measurements into a numerical ocean model using data from High Frequency Radar (HFR) systems. Optimal interpolation of the model-predicted velocity and HFR observations is computed in order to derive a supplementary forcing applied at the surface boundary. This work is the first stage in the development of an HFR data...
This paper provides an overview of the Blue Matter application development effort within the Blue Gene project that supports our scientific simulation efforts in the areas of protein folding and membrane-protein systems. The design philosophy of the Blue Gene/L architecture relies on large numbers of power efficient nodes (whose technology is derived from the world of embedded microprocessors) to...
