Blockchain based uniform price double auctions for energy markets
(2019)The energy sector is undergoing a massive transformation that greatly affects and is being affected by its market mechanisms. This paper presents the design, the prototype implementation and the analysis of a decentralized, ... -
A converged network architecture for energy efficient mobile cloud computing
(2014)Mobile computation offloading has been identified as a key enabling technology to overcome the inherent processing power and storage constraints of mobile end devices. To satisfy the low-latency requirements of content-rich ... -
Cross-layer design for power efficiency and QoS provisioning in multi-hop wireless networks
(2006)In recent years, it has become common consensus that independent consideration of communication layers often turns out to be inadequate in terms of providing the desired quality of service (QoS) and power efficiency in ... -
Electrocatalytic production of hydrogen over highly efficient ultrathin carbon encapsulated S, P co-existence copper nanorods composite
(2020)Electrocatalysis plays a key role in energy conversion processes (such as hydrogen evolution reaction-HER) to several renewable energy technologies developed to reduce our dependence on fossil fuels. It is of great importance ... -
Energy and CO2 emissions as the determinants of countries' productivity with different levels of economic development
(2017)In the present study, Data Envelopment Analysis (DEA) is used for the period spanning from 1980 to 2012 and for a total of 32 countries which are classified into four groups, according to their level of development ... -
Energy aware buffer aided cooperative relay selection
(2014)In this paper we evaluate an energy-aware relay selection mechanism which exploits channel state information and the availability of buffers at relays to perform flexible relaying based on a backpressure-driven optimization ... -
Impact of technical and efficiency changes on productivity
(2018)Better management of natural capital, an efficient allocation of resources and technological progress can contribute to productivity change. The present study uses data envelopment analysis to determine the total factor ... -
The Impact of Transmit Rate Control on Energy-Efficient Estimation in Wireless Sensor Networks
(2012)We study the impact of physical layer (PHY) transmit rate control on energy efficient estimation in wireless sensor networks. A sensor network collects measurements about an unknown evolving process. Each sensor controls ... -
Influence of growth and urbanization on CO2 emissions: The moderating effect of foreign direct investment on energy use in BRICS
(2022)This study analyses the relationship between foreign direct investment, economic growth, urbanization, energy use, and carbon emissions in Brazil, Russia, India, China, and South Africa (BRICS countries) between 1990 and ... -
Joint Task Migration and Power Management in Wireless Computing
(2009)We investigate a wireless computing architecture, where mobile terminals can execute their computation tasks either 1) locally, at the terminal's processor, or 2) remotely, assisted by the network infrastructure, or even ... -
Performance analysis of a grid-connected photovoltaic park after 6 years of operation
(2019)The growth of renewable energy and especially photovoltaic energy in Greece is remarkable. There exist many grid-connected systems in Greek territory which have completed ten years operation. A challenging task for these ... -
Seeking for convergence in the agricultural sector performance under the changes of Uruguay round and 1992 CAP reform
(2019)This paper builds on the knowledge generated by the past studies on agricultural convergence and extends it in order to provide a more holistic analysis in geographical terms, and a more detailed analysis of the aspects ... -
Urban energy efficiency assessment models from an AI and big data perspective: Tools for policy makers
(2022)Although energy efficiency is quite a cliché term, it is a topic that attracts an increasing attention the last decade, especially in the context of cities and as a means to address emerging challenges like sustainability ...
