Evaluating impact of storage on smartphone energy efficiency

Proceedings of the 2013 ACM conference on Pervasive and ubiquitous computing adjunct publication, 2013
We present an experimental study of how storage techniques impact energy consumption in smartphones. We design and implement a system that tracks I/O activities of smartphones in real-time and dynamically changes storage configuration by matching I/O patterns in order to reduce energy consumption.

Optimal sizing of energy storage for efficient integration of renewable energy

IEEE Conference on Decision and Control and European Control Conference, 2011
In this paper, we study the optimal storage investment problem faced by an owner of renewable generator the purpose of which is to support a portion of a local demand. The goal is to minimize the long-term average cost of electric bills in the presence of dynamic pricing as well as investment in storage, if any.
