The biggest part of the energy consumption buildings is for thermal comfort. Awareness on climate change and concerns about depletion natural resources made necessity to use renewable sources in evident. In this context, microalgae have high surface efficiency consume inorganic carbon, thus enabling carbon-neutral operation. They can be integrated into building façades with photobioreactors red...

Energy-efficient machining strategies are required to be implemented in daily practice to advance the competitiveness of the enterprises on global scale. Energy information, which currently not considered as an integral part of production data, is studied. A need is identified to integrate energy information into production program and solidify the knowledge for extensive reference. To effectiv...

Distillation is responsible for a significant amount of the energy consumption of the world’s process industry and also in the natural gas processing. There is a significant energy saving potential that can be obtained by applying new energy saving distillation technology that has appeared in the last two decades. The fully thermally coupled dividing wall columns have the attractive feature of ...

Energy considerations are important for Internet datacenters operators, and MapReduce is a common Internet datacenter application. In this work, we use the energy efficiency of MapReduce as a new perspective for increasing Internet datacenter productivity. We offer a framework to analyze software energy efficiency in general, and MapReduce energy efficiency in particular. We characterize the pe...

It is now critical to reduce the consumption of natural resources, especially petroleum to resolve air pollutions. Even in information systems, we have to reduce the total electrical power consumption. A cloud computing system is composed of a huge number of server computers like Google file systems. There are many discussions on how to reduce the total power consumption of servers, e.g. by tur...

A challenging aspect of mobile communications consists in exploring ways in which the available run time of the terminals can be maximized. In this paper we investigate battery management techniques that can dramatically improve the energy efficiency of radio communication devices. We consider an array of electrochemical cells connected in parallel. Through simple scheduling algorithms the disc...

Rapidly, the world is getting more and more connected. Internet plays a prominent role in this trend. Furthermore, people are becoming increasingly mobile. The combination of both trends results in a huge demand for wireless communication. This thesis addresses the problem of energy-efficient wireless communication with an adequate quality of service. The scarce energy resources of a mobile req...

In this chapter we present an energy-efficient highly adaptive network interface architecture and a novel data link layer protocol for wireless networks that provides Quality of Service (QoS) support for diverse traffic types. Due to the dynamic nature of wireless networks, adaptations in bandwidth scheduling and error control are necessary to achieve energy efficiency and an acceptable quality...
