Bioresource Technology, 2012
The effect of ratio between autoflocculating and target microalgae in bio-flocculation was studied with emphasis on the recovery, sedimentation rate and energy demand for harvesting the target microalgae. When the autoflocculating microalgae Ettlia texensis, Ankistrodesmus falcatus and Scenedesmus obliquus were added to Chlorella vulgaris at a ratio of

Energy storage variation ratio and power efficiency of Cuk converter in continuous mode
2015 6th International Conference on Power Electronics Systems and Applications (PESA), 2015The amount of storage energy in comparison to the output energy for basic topologies deserves deep research which was proposed over ten years ago. It has been analyzed and demonstrated that the larger is the energy variation ratio of power devices including inductors and capacitors, the larger is power loss, thus lower efficiency.

Performance-to-Power Ratio Aware Virtual Machine (VM) Allocation in Energy-Efficient Clouds
2015 IEEE International Conference on Cluster Computing, 2015The last decade witnesses a dramatic advance of cloud computing research and techniques. One of the key faced challenges in this field is how to reduce the massive amount of energy consumption in cloud computing data centers. To address this issue, many power-aware virtual machine (VM) allocation and consolidation approaches are proposed to reduce ...

In cooperative communication, different ratio combining approaches can be utilized at the receiver based on the channel state information (CSI) available to the destination. In this paper, we focus on optimal energy allocation under amplify-and-forward (AF) cooperative communications when various ratio combining methods are utilized. More specifically,
