The limitations of limitations
IEEE Intelligent Systems, 2003The authors consider human-centered computing, and argue that human factors and applied cognitive psychologists have not just been selective in regarding certain human characteristics as limitations, but have also selected the wrong things and for the wrong reasons.

Global Biogeochemical Cycles, 2017
AbstractPhosphorus is believed to be the globally limiting nutrient in the modern ocean, but a number of nutrients have been invoked as limiting the Proterozoic biosphere. Mass balance calculations suggest that Proterozoic net primary productivity must have been 1 to 2 orders of magnitude less than today in order to maintain low oxygen levels despite ...

The Limits of the Nonlinear Shannon Limit
Optical Fiber Communication Conference, 2016Recent results about information theoretical limits in optical fibers are reviewed and the significance of what is commonly known as the nonlinear Shannon limit discussed. It is shown that this limit can be improved, while the actual channel capacity at high powers still remains substantially unknown.

Today, traffic noise due to cars, trains, and airplanes is the main noise source in urban areas. In accordance with the European Commission’s Green paper on Future Noise Policy, 22% of the European population are exposed to outdoor A-weighted noise levels higher than 65 dB and more than 45% are exposed to levels between 55 and 65 dB.

The Limitations of “Limitations”
The American Journal of Bioethics, 2004It is heartening to see the authors of “Limitations” (Levine et al. 2004) lamenting that, as a salient concept in research ethics, vulnerability has been a mess.

Barriers, Limits and Limitations to Resilience
Journal of Extreme Events, 2015Enhancing resilience has become a key element of preparedness for extreme events and climate change. While much progress has been made in defining components of resilience, many questions remain about identification of appropriate strategies for building resilience, barriers to implementation of these strategies, and limits to the potential ...
