PhD
Mining questions about software energy consumption- [Pinto et al., 2014]
Mining energy-greedy API usage patterns in android apps: An empirical study- [Linares-Vasquez et al., 2014]
Seeds: A software engineer’s energy-optimization decision support framework- [Manotas et al., 2014]
Calculating source line level energy information for android applications- [Li et al., 2013]
Initial explorations on design pattern energy usage- [Sahin et al., 2012]
How does code obfuscation impact energy usage?- [Sahin et al., 2014]
Pre-Thesis
PhD Research Questions
6
1. Is it possible to accurately detect and identify energy faults? 2. Can these energy faults be optimized without the expense of
program functionality?3. Can we show this information in a manner allowing programmers to
become energy-aware while programming?
