Systems that can track and intelligently adapt to changes in users’ cognitive capacities may help to improve human performance. The experiment reported here was designed to assess the benefit of placing neuro-physiological sensors on users to provide data about their cognitive states that can drive performance mitigations. A test group of 16 participants performed a primary task while monitorin...

Shallow water marine seismic surveys are necessary to understand a range of Earth processes in coastal environments, including those that represent major hazards to society such as earthquakes, tsunamis, and sea-level rise. Predicting the acoustic radiation of seismic sources in shallow water, which is required for compliance with regulations designed to limit impacts on protected marine specie...

Triple Modulo Redundancy (TMR) is one of the most common techniques for fault mitigation in digital systems. TMR-based computing has a natural application to mission critical systems for military and aerospace applications which are exposed to cosmic radiation and are susceptible to Single Event Upsets (SEUs). TMR’s increased immunity to SEUs comes at the expense of increased power consumption ...

Risk perceptions are the basis for radon risk decisions by both scientists and the general public. Since radon cannot be detected by any of our five senses, which most people rely upon to warn them of danger, much of the general public does not perceive radon as a significant risk. Likewise, many health physicists, with many years of training and experience in dealing with significant radiation...

Adaptation to climate change and mitigation of climate change are policy substitutes, as both reduce the impacts of climate change. Adaptation and mitigation should therefore be analysed together, as they indeed are, albeit in a rudimentary way, in cost-benefit analyses of emission abatement. However, adaptation and mitigation are done by different people operating at different spatial and temp...

Encouraging individuals to take action is important for the overall success of climate change mitigation. Campaigns promoting climate change mitigation could address particular groups of the population on the basis of what kind of mitigation actions the group is already taking. To increase the knowledge of such groups performing similar mitigation actions we conducted a population-based cross-s...

During the year 200 1 there were severe electrical energy problems in California. There were several instances when localized electricity blackouts were imposed due insufficient power generation capabilities. In response some citizens simply disconnected their radon system, and several inquired as to the advisability of using a timer to interrupt the fan operation. In this paper I will present ...

SRAM-based FPGAs are increasingly popular in the aerospace industry due to their field programmability and low cost. However, they suffer from cosmic radiation induced Single Event Upsets (SEUs). In safety-critical applications, the dependability of the design is a prime concern since failures may have catastrophic consequences. An early analysis of the relationship between dependability metric...
