Energy Policy, 2014
Abstract Energy lies at the backbone of any advanced society and constitutes an essential prerequisite for economic growth, social order and national defense. However there is an Achilles heel to today׳s energy and technology relationship; namely a precarious intimacy between energy and the fiscal, social, and technical systems it supports. Recently,

Green Metrics for Energy-aware IT Systems
2011 International Conference on Complex, Intelligent, and Software Intensive Systems, 2011This paper presents a novel approach to characterise applications with respect to their energy consumption by using a set of energy-related metrics, called Green Metrics. These indicators are based on energy consumption measurements, such as indexes of computing resource usage, of environmental impact, and even of development costs required to (re ...

Energy Proportionality and the Future: Metrics and Directions
2010 39th International Conference on Parallel Processing Workshops, 2010This paper proposes a pair of quantitative metrics, namely the idle-to-power ratio (IPR) and the linear deviation ratio (LDR), to be used together for measuring the energy proportionality of computing systems. The metrics are applied to the publicly available SPECPower_ssj2008 benchmark results, yielding a partly grim trend of energy proportionality ...

A Survey of Internet Energy Efficiency Metrics
Proceedings of the 5th International Conference on Smart Cities and Green ICT Systems, 2016Several metrics have been widely applied to quantify the “energy efficiency” of the Internet and ICT. In this paper we analyse and compare these metrics when applied to telecommunication network equipment, networks and services. We show that different metrics can imply different, and possibly conflicting, strategies for improving energy efficiency ...

Energy metrics of fuel juxtaposed with mass yield metrics
Renewable Energy, 2020Abstract Without oxygen, there would be no combustion. Yet the crucial role of oxygen in energy systems has been largely underrepresented. The oxygen-dependence of fuel caloricity is used to derive energy-based metrics that challenge the prime facie objective of maximising biofuel mass yields—an objective that currently dominates the biofuel industry.

A new energy aware performance metric
Computer Science - Research and Development, 2010Energy aware algorithms are the wave of the future. The development of exascale systems made it clear that extrapolations of current technologies, algorithmic practices and performance metrics are simply inadequate. The community reacted by introducing the FLOPS/WATT metric in order to promote energy awareness.

Performance metrics for energy spectrum estimation
2017 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2017Nuclear spectroscopy frequently involves estimating the distribution of photon energies (energy spectrum). The evaluation of spectral estimates within the literature are often subjective. Efforts to quantify the quality of the estimation generally utilize a measure based on the integrated square of error.

Tracing and Visualization of Energy-Related Metrics
2012 IEEE 26th International Parallel and Distributed Processing Symposium Workshops & PhD Forum, 2012In an effort to reduce the energy consumption of high-performance computing centers, a number of new approaches have been developed in the last few years. One of these approaches is to switch hardware to lower power states in phases of device idleness or low utilization.

A Psychovisual Quality Metric in Free-Energy Principle
IEEE Transactions on Image Processing, 2012In this paper, we propose a new psychovisual quality metric of images based on recent developments in brain theory and neuroscience, particularly the free-energy principle. The perception and understanding of an image is modeled as an active inference process, in which the brain tries to explain the scene using an internal generative model.
