Deep-sea Mining: An Emerging Marine Industry

Deep-sea mining is an emerging marine industry that presents particularly complex challenges due to its multi-faceted technological, scientific, environmental, social, industrial, political, economic and legal aspects, all of which must be addressed to achieve commercially viable results. These aspects are governed by the burgeoning regulatory regime promulgated by the International Seabed Auth...

Deep sea in deep trouble?

Ahead of the imminent start of the industrial exploitation of deep sea resources, an EU report finds that scientific knowledge and understanding of this environment and its ecosystems still fall short of what would be needed for a sustainable use.

An Improved Ganglia-like Clusters Monitoring System1

Ganglia [1] is a scalable distributed monitoring system for high performance computing systems such as clusters and Grids. We propose an improved Ganglia-like clusters monitoring system, which has more reliability with federation node and associated link failures; some monitoring data is accessed by permission; adding control functions such as restart or shutdown confusion processes; send email...

An inexpensive blackbody model

A blackbody is a fundamental concept in thermography. A perfect model of blackbody is characterized by emissivity =1 which is difficult to be obtained. There are black body simulators which are being used for calibration of infrared devices. Commercial solutions of blackbody simulators are based on mathematical models of cavity or surface blackbodies and their emissivity is closer to unity e.g....
