Broader perspectives for comparing different greenhouse gases.
Over the last 20 years, different greenhouse gases have been compared, in the context of climate change, primarily through the concept of global warming potentials (GWPs). This considers the climate forcing caused by pulse emissions and integrated over a fixed time horizon. Recent studies have shown that uncertainties in GWP values are significantly larger than previously thought and, while pas...
متن کاملVisible light communications: demand factors, benefits and opportunities [Guest Editorial]
isible light communications (VLC) is an emerging field of optical communications that focuses on the part of the electromagnetic spectrum that humans can see. Much existing work in optical communications exists, mainly optimized for capacity and transmission performance in fiber and free-space with biases toward spectrum that minimizes attenuation in the medium. However, the use of the visible ...
متن کاملEnergy harvesting communications: Part III [Guest Editorial]
as a promising approach to enable self-sufficient and self-sustaining operation for devices in energy-constrained networks by scavenging energy from the ambient environment to power up devices. In particular, for wireless sensor networks, if the sensors, which spread throughout homes or factories, in buildings or even outdoors, are powered by energy harvesting, there are no batteries to replace...
متن کاملGuest Editorial Energy-Efficiency in Optical Networks
THE increasing concern for environmental and cost issues has made energy efficiency in telecom networks an important theme. According to a recent report [1], today’s networks are wasting a lot of energy by consuming 10,000 times more energy than what is really needed. The Internet currently consumes about 0.4% of the total electricity in broadband-enabled countries and is foreseen to quickly re...
متن کاملGuest Editorial on Metadata
This is a special issue on the topic of metadata. An often-cited de®nition of metadata is `data about data'. In most cases, this means data that describe documents, for example, the author of a document, the date that a photograph was taken, or the Universal Resource Locator (URL) of a Web site. The World-Wide Web Consortium de®nes metadata as `machine understandable information for the Web' <h...
