Energy: Quality and Efficiency

Exploring Energy Efficiency and Service Quality of Airlines with Cruise Speed Control

In the past decade, fuel consumption and CO2 emission have increased in the airline industry. Large CO2 footprint has a damaging effect on the environment. Global concerns over this issue has made the airline industry to be greener. Most efforts of the green airline industry are improving the fuel consumption to reduce the CO2 emission and its environmental damage. Here, we use cruise speed con...

Collaborative Smart Environments for energy-efficiency and quality of life

In line with the goals of Europe 2020 strategy, energy resource saving represent a key issue for smart, sustainable and inclusive growth. Recent developments in ICTs offer home devices featuring local intelligence and connectivity services. So, basing on such technologies, a house becomes Collaborative Smart Environment (CSE), a place where multimedia services are provided to users, while heter...

Energy Efficiency and Indoor Air Quality in Schools

Overview In the 1998-99 school year, U.S. K-12 public schools provided instruction to over 46 million students. An estimated 70% of all school buildings have indoor air quality (IAQ) problems, leading to an unhealthy environment. Because children breathe a greater volume of air relative to their body weight compared to adults, they may be more sensitive to indoor air pollution. Additionally, oc...

Energy Efficiency and Delay Quality-of-Service in Wireless Networks

The energy-delay tradeoffs in wireless networks are studied using a game-theoretic framework. A multi-class multipleaccess network is considered in which users choose their transmit powers, and possibly transmission rates, in a distributed manner to maximize their own utilities while satisfying their delay quality-ofservice (QoS) requirements. The utility function considered here measures the n...
